Copepods of the genus Colobomatus (Poecilostomatoida: Philichthyidae) from fishes of the family Sillaginidae (Teleostei: Perciformes)

Six species of Colobomatus, five of which are new to science, were found in a survey of 26 species of sillaginid fishes in the Indo-west Pacific. Three of the species are closely related and occur in the head cavities of various species of their hosts. Colobomatus sillaginis West, 1983 is recorded in Sillaginodes punctata and 12 species of Sillago, from around the coast of Australia and in the Gulf of Thailand, representing many new host and locality records. Female C. asiaticus sp. nov. are described from southeast Asia and the Persian Gulf, in three species of Sillago. Female C. arabicus sp. nov. are described from two species of Sillago occurring only in the Persian Gulf. A second intrageneric grouping of three species of Colobomatus inhabits a different microhabitat: tubes of the lateral line scales. Each of these species infects several sillaginid fishes, and in contrast to members of the first species-group they are entirely allopatric with each other. In Australia, female C. fulloonae sp. nov. are described from three species of Sillago in northern waters, and female C. charleah sp. nov. are described from two species of Sillago and Sillaginodes punctata in southern waters. Female C. westi sp. nov. are described from three species of Sillago in the waters of eastern Asia (Japan, Korea and China). Only one male specimen of each of C. arabicus sp. nov., C. charleah sp. nov. and C. westi sp. nov. was found.     

Recent species of the Family Candonidae (Ostracoda,Crustacea) from the ancient Lake Biwa,Central Japan

Sampling of Lake Biwa between November 1997 and February 2007 has revealed a diverse Candonidae fauna consisting of 18 species. Eleven are previously undescribed species, belonging to the genera Fabaeformiscandona (nine species), Pseudocandona (one species) and Cypria (one species), and 10 of these are potentially endemic to the lake. In total there are 12 Fabaeformiscandona species in the lake belonging to two sub‐groups based on the number of setae on the mandible palp, the fabaeformis‐group (10 species) and the acuminata‐group (two species). Including the new Fabaeformiscandona species described herein, Lake Biwa is home to 19% of the approximately 62 described living species of this genus known globally. Although, the new Fabaeformiscandona species are potentially endemic, they do not show a microevolutionary pattern similar to that suggested for the Tanganyikan Cyprideis species flock.     

LXXXI.—Notes on the classification of the African monkeys in the genus Cercopithecus,erxleben

Summary

The Ethiopian species of the genus Agrypon Foerster (Anomaloninae) are revised and a key is given to the eight species. Four species, A. zebrinum, A. omum, A. seyrigi and A. hancocki, are described as new and three new synonymies are proposed. A. leucostomum (Cameron) is newly transferred to Agrypon. Notes on the phylogeny of the species are included.     

Seed-feeding beetles of the weevil tribe Mecysolobini (Insecta: Coleoptera: Curculionidae) developing in seeds of trees in the Dipterocarpaceae

Species comprising two monophyletic groups of Alcidodes sensu lato (crassus group and dipterocarpi group) feed on fruits of the ecologically and economically important tropical timber family Dipterocarpaceae. Fifteen Alcidodes species are newly described from several thousand specimens of seed-feeding beetles reared from south-east Asian dipterocarp hosts (Dipterocarpoidae) and four other species are revised. Morphological keys are provided for identifying these 19 taxa. Weevil associations are provided for 70 species of Dipterocarpaceae in five genera (16 Dipterocarpus spp., four Dryobalanops spp., six Hopea spp., 39 Shorea spp. and five Vatica spp.). These records relate primarily to specimens reared from seeds in Borneo and in Peninsular Malaysia, but all known previous host records are also included (from India, Andaman Islands, Thailand, Laos, Vietnam and the Philippines) and assessed. These validated and documented host associations refute general assertions that (1) seed-eating beetles are host-specific in the tropics and (2) seed-eating beetles found on dipterocarp hosts are broad generalists across species in several genera of mast-fruiting Dipterocarpaceae. Most Alcidodes species exploit seeds from several dipterocarp species. Some Alcidodes species occur across broad geographic regions with several host species from a dipterocarp genus, other species have been found only on Bornean Hopea or Dipterocarpus species. Others, such as the two previously undescribed species feeding on Vatica species, may be restricted to separate sections of the host genus. Within an extensively sampled and diverse interspecific mast-fruiting dipterocarp community, no Alcidodes species was observed to feed on sympatric species across genera within the Dipterocarpaceae. Additional host records and specimens of Alcidodes spp. throughout the range of the Dipterocarpaceae in south and southeast Asia are required to further define these clades and the tribe Mecysolobini in general as well as to resolve the complex host associations and distributions documented.     

The genus Monacha in the Western Caucasus (Gastropoda: Hygromiidae)

Seven Monacha species have been found in the Western Caucasus region. Six of these species are endemic there. They all belong to the subgenera Paratheba and Metatheba. Three species are new to science. M. (Paratheba) claussi, sp. n. and M. (Metatheba) subcarthusiana (Lindholm) are the only Monacha species, in which the right ommatophoral retractor sometimes crosses with the penis. This might be due to an ancestral polymorphism, atavism or a basal position of the two species within Monacha, which would mean that Paratheba is paraphyletic and Metatheba is polyphyletic. Monacha (Monacha) cartusiana (O. F. Muller), the only Monacha sensu stricto species in the Caucasus region, has probably been introduced by man. The shell and the genitalia of every species are described and illustrated. The synonyms and all Caucasian locality records are listed. The distributions of the species are illustrated on UTM-grid maps.     

A report on the cheilostome Bryozoa of the Sudanese Red Sea

Summary

Eighty-six species of bryozoa are listed from collections from reefs in the Sudanese Red Sea, increasing the known fauna list by 30 species. The abundance, in terms of numbers of colonies, and the distribution of nineteen species has been analysed over a range of 30 metres depth. The character of the genera Calyptotheca Harmer and Emballotheca Levinsen are briefly discussed. C. thornelyae is introduced for Lepralia subimmersa Thornely not MacGillivray, and E. harmeri for E. acutirostris Harmer not Canu and Bassler. In addition, three new species of Calyptotheca, C. heteroavicularia, C. nigra and C. sudanensis, and one of Escharoides, E. longirostris, are described.     

Taxonomy of the Cecropia-inhabiting Azteca ants

Cecropia trees and several species of the ant genus Azteca form the most conspicuous ant-plant association in the Neotropics. The taxonomy and biology of the Cecropia-associated Azteca are reviewed. A key to queens is provided for the 13 species known to be obligate inhabitants of Cecropia trees, and a key to workers for the five species known from Costa Rica. Taxonomic changes include four new species and extensive synonymy. Individual species accounts contain taxonomic, behavioural, and ecological information. Evolutionary relationships among the species, and the community ecology of the Cecropia-Azteca association, are discussed.     

Distribution of bisexual and unisexual species in the aphid genus Colopha Monell (Aphididae: Eriosomatinae), with the description of a new species in Japan

Aphids of the genus Colopha are represented by three bisexual and three unisexual species. The bisexual species are associated with two Ulmus species that are most closely related, being distributed disjunctively in Europe and eastern North America on the host plants. A new unisexual species of Colopha, collected from Setaria chondrachne (Poaceae) in Japan, is described under the name Colopha setaricola sp. nov. The distribution of the three unisexual species is discussed in relation to aphid‐plant associations and historical changes in the distribution of the host plants. It is suggested that these unisexual species have persisted on the secondary hosts through parthenogenetic reproduction since the extinction of the primary host plants, Ulmus species section Blepharocarpus. Therefore, the unisexual species in Colopha exemplify Mordvilko's hypothesis that unisexual species on the secondary host plants have remained as relics in the region where the primary host was once distributed but then became extinct.     

Revision of the Trogidae of South America (Coleoptera: Scarabaeoidea)

The South American Trogidae are revised. Three genera, Trox Fabricius, Omorgus Erichson (with two subgenera, Omorgus and Haroldomorgus Scholtz), and Polynoncus Burmeister, and 47 species are recorded from the continent and its islands. Trox is represented by the ubiquitous introduced species T. scaber (L.), Omorgus is represented by 13 species and Polynoncus by 33 species. Five new species are described and all others are re-described. A key to all taxa is provided. Adults of all species and their male genitalia are illustrated and their distributions mapped. Observations are presented on phylogeny, zoogeography and biology. The new species are O. capillaceus, O. indigenus, O. nocheles, P. erugatus and P. gibberosus. Four new synonymies are proposed (synonyms listed first): O. triestinae Pittino = P. suberosus (Fabricius); P. furcifer Pittino = P. bifurcatus (Vaurie); P. parafurcatus occidentalis Pittino and P. furcillifer Pittino = P. parafurcatus Pittino. Omorgus badeni (Harold) is reinstated as a valid species. Lectotypes are designated for O. batesi (Harold) and O. badeni (Harold).     

In search of the true Tydeus (Acari,Tydeidae)

The early history of the genus Tydeus, the type genus of the family Tydeidae, is complex and convoluted and, subsequently, even the identity of the type species of the family remains unclear. First, the literature is thoroughly analysed and morphological characters of some species are reappraised. After studying Oudemans' types, two species inquirendae, Tydeus croceus and T. cruciatus, are redescribed and a third, T. spathulatus, removed from synonymy and reinstated as a valid species. A fourth species, confused with T. spathulatus, is described. A lectotype is designated for T. spathulatus and a neotype for T. croceus. After discussion, the genus Lorryia Oudemans, is re‐established in its pristine state. As the redescribed species were designated as type species by Oudemans, the following new generic synonymies are proposed: Raphitydeus Thor, and Lorryia Oudemans, sensu Ka?mierski (, ) are junior synonyms of Brachytydeus Thor, ; Homeotydeus André, (partim) and Pseudolorryia Ka?mierski, are junior synonyms of Calotydeus Oudemans, ; Brachytydeus Thor, (partim), Calotydeus Oudemans, (partim), Tydeus Koch, sensu Oudemans, (partim), Orthotydeus André, , and Tydeus Koch, sensu Ka?mierski, are junior synonyms of Tydeus Koch, . To stabilize the usage of the names, especially that of the genus type of the family Tydeidae, the International Commission of Zoological Nomenclature will be asked to set aside all previous type species designations for Tydeus and to designate Tydeus spathulatus as the type species, with Oudemans' specimens from Italy as primary type material.     

Systematic study on the barracudas (Pisces: Sphyraenidae) from a northern sector of the South China Sea

Summary

The paper here provides an effective key for separation of species of the genus Sphyraena Röse from the northern part of the South China Sea for both taxonomic and field identifications. Six species, namely S. barracuda (Walbaum, 1792), S. jello Cuvier, 1829, S. novaehollandiae Günther, 1860, S. pinguis Günther, 1874, S. toxeuma Fowler, 1904, and S. africana Gilchrist and Thompson, 1909, are listed in the key. All except S. barracuda were found during this study. Generic and species problems are discussed and comparisons of each species are made with closely related forms. The species names adopted in this paper are also explained. The first record of S. novaehollandiae from this area is reported.     

Australian thrips of the Haplothrips lineage (Insecta: Thysanoptera)

Keys are presented to the 11 genera and 50 species, including 21 new species, of Thysanoptera in Australia that are related to the worldwide genus Haplothrips Amyot and Serville. These taxa belong to what, in recent literature, has been called the “Haplothrips‐lineage”, that is, one of the three major radiations among the 2700 species and 350 genera of Thysanoptera Phlaeothripinae. The group is redefined, and the available tribal name Haplothripini shown to be appropriate. The character states on which the definition is based are discussed, and a list given of the 34 genera worldwide that can be included. The Australian species in these genera exhibit a diversity of biologies. Three genera involve species that invade galls induced by other thrips: Androthrips monsterae (Moulton) from New Guinea is newly recorded from Australia; Mesothrips jordani Zimmermann from South‐East Asia is newly recorded from Australia, with two new synonyms; the Asia‐Pacific genus, Euoplothrips Hood, includes two species in northern Australia. Three haplothripine genera are associated with grasses: one widespread genus, Apterygothrips Priesner, considered polyphyletic, includes only one Australian species; the only known species of Dyothrips Kudo is Oriental but extends into tropical Australia; Podothrips Hood, a circum‐tropical genus of thrips predatory on grass‐living coccoids, has 11 Australian species, six newly described. One grass‐associated genus, Bamboosiella Ananthakrishnan, is excluded from the Haplothripini. An Oriental genus of leaf‐ and flower‐living species, Dolichothrips Karny, includes one species in northern Australia, D. reuteri (Karny); Membrothrips Bhatti in which this species has been placed is considered a synonym. Karnyothrips Watson includes two species introduced to Australia, both predators of coccoids. Priesneria Bagnall includes three species from Australia, of which one fungus‐feeding species is newly described. Xylaplothrips Priesner is a widespread but ill‐defined, polyphyletic genus that currently includes three little‐known Australian species. Haplothrips is the main focus of this study, and character state variation among the Australian species is discussed. In total 24 species of Haplothrips from Australia are recognised, 14 being new species. Also included are the following, one new generic synonym, four new species synonyms, and one new combination. The 250 species worldwide in the genus are usually associated with the flowers of Asteraceae and Poaceae. In Australia, several of the species are specific to flowers, particularly of Poaceae and Cyperaceae but not Asteraceae. Almost half of these Australian species are presumed to be predatory on other small arthropods, and two have unusual host associations—with salt marsh Chenopodiaceae, and with the sori of Dicksonia tree ferns.     

Poecilostome copepods (Lichomolgidae) associated with the scleractinian coral Galaxea in the Moluccas

Summary

Nine species of Scirtothrips are here recorded from the Australasian region, eight from Australia and two including one endemic species from New Zealand. A key is provided for their identification, and diagnostic details and collection notes are given for each species. Two new species, S. casuarinae and S. helenae are described from Australia and one new synonym, S. gladiiseta Girault = Dendrothripoides ipomeae Bagnall, is recorded.     

The genus Platypalpus Macquart (Diptera: Hybotidae) from Northeast Thailand with comments on the species groups in the Oriental region

The first records on the genus Platypalpus Macquart from Thailand are presented including 10 species new to science: P. fai sp. nov., P. gaemluang sp. nov., P. hualuang sp. nov., P. isaanensis sp. nov., P. nuadkhao sp. nov., P. phomyaaw sp. nov., P. seedam sp. nov., P. seeluang sp. nov., P. siamensis sp. nov., and P. thaicus sp. nov.. A key to these species is provided. All species of Platypalpus known from the Oriental Region (totally 54) are arranged into the species groups currently established for the genus. Eight species groups are recognized from the Oriental Realm and the distribution of each group is briefly discussed. The P. albiseta‐group is most diverse in the Orient with 16 species recorded. Two species of this group possess a modified structure and vestiture of certain abdominal segments that is the first record of this phenomenon in Platypalpus. Also, within the P. albiseta‐group a complex of closely related species sharing an apomorphous condition of the hypoproct has been recognized. In these species the structure of the hypoproct is likely to deal with clasping during copulation instead of the cerci and epandrial lamellae.     

Deep-sea asellote isopods (Crustacea,Eumalacostraca) of the north-west Atlantic: the family Haploniscidae

The deep-sea asellote isopod species belonging to the family Haploniscidae were studied from three study sites off the North Carolina coast and one off Bermuda. The following five new species, belonging to the new genus Chandraniscus, are described: C. kussakini from Alpha-A off Bermuda (1300 m), C. eastwardae, C. costlowi and C. chardyi from the Carolina lower slope site Beta and C. negoescuae at site Sigma on the Carolina continental rise (4910 m). Three new species of Haploniscus are described: H. kensleyi from the Carolina upper continental slope at Alpha-B, H. gnanamuthi from site Alpha-A off Bermuda, H. harrietae from site Beta. A new species Chauliodoniscus wilsoni from site Sigma is also described. Three new species of the genus Hydroniscus, found in this alpha-taxonomic study, include H. buzwilsoni and H. malyutinae from site Beta and H. watlingi from both Beta and Sigma. Two new species of the genus Antennuloniscus, A. menziesi and A. lincolni, are described from site Beta over the Carolina lower continental slope.     

A taxonomic review of the Rhinotermitidae (Isoptera) of Thailand

Ninety series of rhinotermitid termites were collected from 19 localities distributed across much of Thailand, and compared with specimens deposited in the NHML. Eleven species belonging to five genera of Rhinotermitidae are recorded from Thailand. Three species of two genera, Reticulitermes (Reticulitermes assamensis) and Parrhinotermes (Parrhinotermes microdentiformisoides and Parrhinotermes buttelreepeni), are new records from Thailand. Keys to the genera and species based on the soldier caste are given. Soldiers of all species are illustrated and morphological measurements are given.     

Demosponges of the red coral bottoms from the Alboran Sea

This paper deals with a study of demosponge fauna inhabiting the red coral facies on the circalitoral bottoms surrounding the Alboran Island (Western Mediterranean, Alboran Sea). A total of 58 species were recognized, after examining a total of 107 sponges. Two of these species are new to science (Plakinastrella mixta sp. nov. and Leptolabis megachela sp. nov.) and another one (Rhaphidectyon spinosum Topsent) is recorded for the first time in the Mediterranean. Some other specimens collected belonging to poorly known species, such as Erylus papulifer Pulitzer-Finali, Isops anceps (Vosmaer), Spongosorites flavens Pulitzer-Finali and Timea cumana Pulitzer-Finali, are described briefly. Two controversial specimens, assigned to Microciona spinarcus and Plocamilla cf. novizelanica, are also described and discussed. A high degree of epibiosis and abundance of rare species were the major features characterizing the material studied.     

Key to the Holarctic species of Anagrus Haliday (Hymenoptera: Mymaridae) with a review of the Nearctic and Palaearctic (other than European) species and descriptions of new taxa

The Holarctic species of the genus Anagrus Haliday are keyed. The Palaearctic species, other than the European ones revised earlier by Chiappini (1989), and 10 out of 11 valid species described from the Nearctic region are reviewed, based on a study of their type material. Two new species, A. rilensis Donev sp. n. and A. longitibialis Donev sp. n., are described from Bulgaria. A new specific synonymy is proposed: A. giraulti Crawford, 1913 with A. nigriventris Girault, 1911 (described as A. armatus var. nigriventris). New replacement name: A. oregonensis S. Triapitsyn nom. n. pro A. nigriceps Girault, 1915 (A. armatus var. nigriceps) nec Smits van Burgst, 1914. A. spiritus Girault, 1911 and A. columbi Perkins, 1905 are reinstated as valid species. A checklist of 68 presently recognized species of Anagrus is given in accordance with their distribution in different biogeographic regions.
