L.—Notes on Cecidomyidæ

Resumé

This paper is mostly concerned with records of mites new to the British Isles. Odd notes on the biology of some species previously recorded from these islands deal with various aspects of the general biology of the different species. The following species are described as new to science:—Parasitus hibernicus, Phaulodiaspis euris, Ettmulleria dipterorum, and Schwiebea boletophagi. The newly discovered male of Polyaspinus cylindricus Berl. is described fro the first time and its importance in the study of the comparative parative morphology of the Mesostigmata is discussed. The division of the genus Pergamasus by Hull in 1918 is treated in some detail and his subgenera, Plesiogamasus, Paragamasus are promoted to generic status. Some remarks are made on the generic divisions of the Hypoaspis complex of the Laelaptidae and two new genera of Dr. Hull, Chamolaelaps and Halbertia, are brought forward and the types of all the above genera of Dr. Hull designated. New records of Leptus porcinus Hull, 1918 are given and the species is figured in detail.     

Systematics and biology of the Rhinocolinae (Homoptera: Psylloidea)

Based on a cladistic analysis, the subfamily Rhinocolinae is redefined to comprise 13 genera and 39 species, of which two genera and eight species remain unnamed. Four new genera and 14 new species are described; one subfamily and one genus are synonymized, and two species are recombined; one lectotype is designated. The subfamily is divided into two groups, one with a Gondwanan distribution comprising four genera in Australia, New Zealand, South America and Africa, and another with Laurasian distribution in the Palaeotropics, the Western Palaerctic and North America comprising nine genera. Twenty-one species develop on host plants in the Rutales, three on Asteraceae, three on Cistaceae and one on Zygophyllaceae. The genus Pistacia (Anacardiaceae) in particular hosts six species whose biology is discussed.     

A re-examination of Periclimenes (Hamiger) novae-zealandiae Borradaile, 1916, and recognition of the pontoniine shrimp genus Hamiger,Borradaile

The syntypes of Periclimenes (Hamiger) novae-zealandiae Borradaile, 1916, the only known specimens, from off North Cape, New Zealand, are redescribed and illustrated. Placed by Kemp (1922) in the genus Periclimenaeus Borradaile, 1915, the species is now removed from that genus and Borradaile's subgenus Hamiger is raised to generic status for its reception. The male specimen is designated as lectotype. The specimens are held in the collection of the British Museum (Natural History).

The genus Hamiger is most closely related to the genera Thaumastocaris Kemp, 1922, and Orthopontonia Bruce, 1982, both monospecific genera, known to associate with sponges. It is considered that H. novae-zealandiae is probably also a sponge associate and that Palaemonetes natalensis Stebbing, 1915 may be closely related.     

XLI.—Note on a Megalosaurian tibia from the lower Lias of Wilmcote,Warwickshire

Summary

A new species of Dolichomiris Reuter from India and another from South Africa are described, while costicollis Berg is excluded, bringing the total number of species in the genus to seven. All species are figured and keyed. D. linearis Reuter is recorded from Australia, New Guinea, Indonesia and the New Hebrides. Lectotypes are designated where necessary. A revised key to the genera of Stenodemini is presented.     

Review of the genus Bolbonaso Emeljanov with checklist and key to Indian Caliscelidae (Hemiptera: Fulgoroidea)

A list of species of the family Caliscelidae Amyot et Serville known from India with data on distribution and sources for identification and a key to genera are given. The genus Bolbonaso Emeljanov, 2007 is revised. A new species, Bolbonaso chandri sp. nov., is described from Eastern India (Assam and Meghalaya States). Bolbonaso tapirifacies (Parshad, 1981) is redescribed and recorded for the first time from Southern India (Karnataka State). The lectotype is designated for Chirodisca eximia (Stål, 1859) which is recorded for the first time from Pakistan. New faunistic data in Nepal are listed for Delhina eurybrachydoides Distant, 1912.     

A revision of the south Asian sisorid catfish genus Sisor (Teleostei: Siluriformes)

The south Asian sisorid catfish genus Sisor is revised. Three new species are described in this study: S. chennuah from the Brahmaputra River drainage, and S. rheophilus and S. torosus from the Ganges River drainage. The body depth, snout length, eye size, shape of the nuchal plate and the numbers of pectoral spine serrations and lateral line ossicles are found to be diagnostic characters for the species. Sisor rabdophorus is redescribed and a neotype designated.     

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.     

New species of cheilostomate Bryozoa collected by the US Antarctic Research Program

Four new species of cheilostomate Bryozoa are described in the genera Chartella, Ogivalia, Melicerita and Cellarinella. The circumArctic genus Chartella is recorded for the first time from the subAntarctic. Alloeoflustra gen. nov. is introduced for three endemic Antarctic Flustridae.     

Taxonomic status of Pseudosiphonops ptychodermis Taylor and Mimosiphonops vermiculatus Taylor (Amphibia: Gymnophiona: Caeciliaidae) with description of a new species

Pseudosiphonops ptychodermis Taylor is designated a junior synonym of Mimisiphonops vermiculatus Taylor, and Pseudosiphonops Taylor is designated a junior synonym of Mimosiphonops Taylor. A new species of Mimosiphonops is described and taxonomy of the genus reviewed. Relationships between Mimosiphonops and the closely related caecilian genera Siphonops and Lutkenotyphlus are discussed.     

Genus Baseodiscus (Nemertea: Heteronemertea): Molecular identification of a new species in a phylogenetic context

A new heteronemertean, Baseodiscus jonasii sp. nov., is described from Guadalcanal, Solomon Islands. It resembles B. delineatus in inner morphology but can be distinguished from this species by its different colour pattern and differences in the nucleotide sequence of the mitochondrial 16S rRNA gene. The monophyletic status of the genus is investigated by reconstructing the phylogeny of six specimens from four species assigned to this genus, together with 22 specimens from nine other heteronemertean genera, using parsimony and Bayesian analysis. The results imply that Baseodiscus is a monophyletic group while several other heteronemertean genera are non‐monophyletic.     

Species of genus Schizotheca Hincks (Bryozoa,Cheilostomata) described in the Atlantic‐Mediterranean region,with notes on some species of Parasmittina Osburn

Material held in collections, originally ascribed to the genus Schizotheca and originating from the NE Atlantic and Mediterranean, is revised. Two new species are described: Schizotheca carmenae sp. nov. from Azores and Portugal, originally cited as Strophiella tubigera [sic], and Schizotheca buski sp. nov. from Cape Verde and Brazil, originally cited as Schizotheca fissa. Schizotheca talismani, also from Cape Verde, is redescribed from original material and transferred to the genus Parasmittina. The Atlantic species Schizotheca tuberigera is redescribed and a new synonymy is established. Schizotheca aviculifera, from Morocco, is also redescribed and a lectotype designated. A lectotype is also chosen for Schizotheca fissa, type species of the genus. Schizotheca lepida, from north France, is considered to be an unrecognizable species.     

A survey of the genus Geometra Linnaeus (Lepidoptera,Geometridae, Geometrinae)

The type genus of the family Geometridae, Geometra Linnaeus, is reviewed. In addition to the 16 species known worldwide, two new species are described: Geometra neovalida sp. nov. from China, and Geometra burmensis sp. nov. from Burma (Myanmar). All the known species are redescribed. Genitalia of all species are described and illustrated, most for the first time. Generic characters based on all species are summarized. The monophyly of the genus and its relationship with allied genera are reviewed and discussed in detail. Most species fall into two species groups, named the papilionaria and smaragdus groups, on the basis of the morphology of the male genitalia. Biological information is provided where available. Illustrations of moths and genitalia are presented.     

A review of the South-East Asian Nasutitermitinae (Isoptera: Termidae), with descriptions of one new genus and a new species and including a key to the genera

This paper describes Snootitermes leuserensis, gen. et sp. nov. (collected from the Leuser Ecosystem, Sumatra), Hirtitermes brabazoni sp. nov. (collected from north Sulawesi) and the major soldier of Ceylonitermes indicola. It also includes a revised generic key to the Nasutitermitinae of Peninsular Malaysia, Java, Sumatra and Borneo and reassigns the South-East Asian Subulitermes-group of termites to the Nasutitermes-group. Aciculioiditermes denticulatus and A. sarawakensis are considered to be junior synonyms of Aciculioiditermes holmgreni. The genera Aciculioiditermes and Proaciculitermes are considered to be junior synonyms of Malaysiotermes. Therefore Aciculioiditermes holmgreni, Proaciculitermes orientalis, P. sabahensis, P. malayanus and P. lowi are all Malaysiotermes species. Tho's (1982, 1992) unpublished new genus (Genus A) is considered to be a new species of Ceylonitermes. Oriensubulitermes borneensis is shown to be a Subulioiditermes species, S. borneensis. Nasutitermes matangensiformis is shown to be a junior synonym of N. matangensis. Havilanditermes is shown to be a junior synonym of Nasutitermes.     

Generic status and redescription of the Mediterranean fish Gobius liechtensteini Kolombatovic, 1891 (Teleostei: Gobioidea), and its affinities with certain American and Indo-Pacific gobies

Summary

A new monotypic genus, Corcyrogobius, is proposed for the gobiid fish, Gobius liechtensteini Kolombatovic 1891, known only from its Adriatic typelocality of Kor?ula, Yugoslavia. The species is redescribed and a lectotype designated from probable syntype material, which also includes examples of Odondebuenia balearica (Pellegrin & Fage, 1907), supposed by Kolombatovic to be adults of G. liechtensteini. The affinities of C. liechtensteini and the related genus Odondebuenia are discussed with reference to American seven-spined gobies, the Indo-Pacific Gladiogobius, and the subfamily Lioterinae, currently placed in the Eleotridae. Overall similarities between these gobies are described, their possible phylogeny outlined, and the Lioterinae transferred to the family Gobiidae.     

A revision and phylogenetic re-evaluation of the family Schizopodidae (Coleoptera,Buprestoidea)

The Schizopodidae (formerly subfamily Schizopodinae, family Buprestidae) is elevated to family status, based on a review of its morphology including wing venation, male and female genitalia, larvae, and also a cladistic analysis of in-group and out-group comparisions. Two tribes are recognized: Schizopodini LeConte with one genus, Schizopus LeConte and Dystaxiini Théry with two genera: Dystaxia LeConte and Glyptoscelimorpha Horn. The genus Schizopus contains two species: S. laetus LeConte and S. sallei Horn with one new subspecies, S. sallei nigricans Nelson. The genus Dystaxia includes two species: D. murrayi LeConte, and D. elegans Fall. The genus Glyptoscelimorpha is separated into two subgenera: G. (s. str.) with two species, G. marmorata Horn, and G. viridis Chamberlin; and G. (Dystaxiella) Knull, new status, with one species, G. (D.) juniperae (Knull), new combination, with a new subspecies, G. (D.) juniperae viridiceps Nelson. All taxa are described and information on variation, type localities, distribution, biology, and comparisons are given for each species. Keys to taxa for tribes to subspecies are provided. Illustrations for all species, including habitus, male and female genitalia and other parts, as well as cladograms of relationships are presented. Lectotypes are designated for the following: Yermoella helferi Obenberger, Dystaxia elegans Fall and Glyptoscelimorpha marmorata Horn. Tables of taxa, characters and character states used in the cladistic analysis 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.     

A new genus with three new species of copepods from the family Diaixidae (Crustacea: Calanoida), and a redefinition of the family

Plankton samples taken in the Gulf of Carpentaria, Australia, yielded material of a new genus containing 3 new species: Anawekia spinosa gen. nov. et sp. nov., A. robusta sp. nov. and A. bilobata sp. nov., which are described herein. The family Diaixidae now contains 12 described species in 2 genera, 9 being in the genus Diaixis. It is noted that 3 of the Diaixis species (including the type species) share some features which are not shared with the remaining 6 species, and that these latter species should probably be placed into a third genus. An amplified redefinition of the family is given.
