A re-examination of 11 species of Otostigmus from the Indo-Australian region described by R. V. Chamberlin based on type specimens in the collection of the Museum of Comparative Zoology,Harvard (Chilopoda; Scolopendromorpha; Scolopendridae)

As a contribution to a revision of the scolopendromorph centipede subgenus Otostigmus of the genus Otostigmus, the type specimens of 11 species described by R. V. Chamberlin from the Indo-Australian region and in the collection of the Museum of Comparative Zoology at Harvard have been redescribed. Of these 11, six are junior synonyms of other Otostigmus species, one is a junior synonym of Rhysida longipes longipes (Newport, 1845) and one a nomen dubium. Only three, namely, Otostigmus amballae Chamberlin, 1913, Otostigmus proponens Chamberlin, 1920 and Otostigmus pamuanus Chamberlin, 1920 are valid.     

On some maerid and melitid material (Crustacea: Amphipoda) collected by the Hourglass Cruises (Florida). Part 2: Genera Dulichiella and Elasmopus,with a key to world Elasmopus

This paper deals with some of the Amphipoda Maeridae and Melitidae, i.e. one species in the genus Dulichiella and two in Elasmopus, collected during the Hourglass cruises, a 28-month sampling programme at 10 stations (5–73 m depth) on the central West Florida shelf. A key to world Elasmopus species is provided.     

New fanworm species (Polychaeta: Sabellidae: Fabriciinae) in the genus Pseudofabriciola Fitzhugh

Three new species are described: Pseudofabriciola quasiincisura from Belize, P. peduncula from Papua New Guinea, and P. sofla from the Gulf of Mexico off Florida. The total number of species in the genus is increased to 11. Pseudofabriciola quasiincisura and P. peduncula are intertidal, whereas P. sofla is from 26 m depth. An additional species from the Gulf of Mexico off Florida (88m depth), known only from a single specimen lacking the branchial crown, is described briefly but not named. Pseudofabriciola sofla and the unnamed species were originally described by Uebelacker (1984) as Fabricia sp. A. An emended definition for Pseudofabriciola is provided. Cladistic relationships of the species described herein are evaluated relative to others in the genus. The depth distribution of Pseudofabriciola, which displays the greatest known range within the Fabriciinae, is also re-examined.     

Distribution of the milliped Tylobolus utahensis Chamberlin, with remarks on T. fredericksoni (Causey) (Spirobolida: Spirobolidae)

Tylobolus utahensis Chamberlin, the only representative of the genus occurring in the southwestern deserts, ranges from central Inyo County, California, to the western periphery of Kane County, Utah. This distribution roughly corresponds to the northern limit of the Mojave Desert ecosystem and is also shown by the millipede Piedolus utus Chamberlin. (Spirobolida: Atopetholidae) and the centipede Theatops posticus (Say) (Scolopendromorpha: Cryptopidae). Tylobolus fredericksoni Causey, ostensibly from Douglas County, Kansas, is designated "" nomen dubium "" and disregarded pending collection of fresh material; Narceus gordanus (Chamberlin) is deleted from South Carolina and Tennessee. Tyobolus uncigerus (Wood) occurs north of the Columbia River in Klickitat County, Washington, and Hiltonius thebanus Chamberlin is referable to Onychelus Cook in the family Atopetholidae.     

A revision of the genus Pandalus (Crustacea: Decapoda: Caridea: Pandalidae)

The genus Pandalus Leach, 1814, is revised based upon the abundant material from collections in various museums or institutions in the world. Altogether 20 species are recognized which appear to form five groups. Nineteen species are recognized in Pandalus, three of which are described as new: P. curvatus from southern Japan, and P. chani and P. formosanus from Taiwan. Four informal species groups are also recognized within the genus: P. montagui group (P. montagui Leach, 1814; P. borealis Krøyer, 1838; P. goniuruStimpson, 1860; P. jordani Rathbun, 1902; P. tridens Rathbun, 1902; and P. eous Makarov, 1935); P. stenolepis group (P. stenolepis Rathbun, 1902; P. curvatus sp. nov.); P. hypsinotus group (P. hypsinotus Brandt, 1851; P. danae Stimpson, 1857; P. prensor Stimpson, 1860; P. gracilis Stimpson, 1860; P. gurneyi Stimpson, 1871; P. nipponensis Yokoya, 1933; P. teraoi Kubo, 1937; P. chani sp. nov.; and P. formosanus sp. nov.); and P. platyceros group (P. platyceros Brandt, 1851; and P. latirostris Rathbun, 1902). The P. platyceros group appears to be most closely related to the genus Pandalopsis Bate, 1888, but Pandalus is retained as a possible paraphyletic group. Protandrous hermaphroditism is known in all but two species of the genus (P. curvatus and P. formosanus), for which only specimens of either male or female have been available. Pandalus propinqvus G. O. Sars, 1870, is transferred to a new monotypic genus Atlantopandalus, because of its lack of hermaphroditism and possession of some unique morphological characters, including one indicating a close relationsip to Dichelopandalus Caullery, 1896. All species are fully described and illustrated. The affinities and important morphological variations of the species are discussed. A key for adults is presented for the identification of the species. Biogeography of the genus is briefly discussed.     

Two new species of Microprosthema from the Western Atlantic (Crustacea: Decapoda: Stenopodidea)

Two new species of shrimp in the genus Microprosthema are described and figured on the basis of materials collected recently from the tropical western Atlantic. Specimens of one, Microprosthema manningi, have been collected from Florida, Mexico, Belize and Old Providence Island. The other new species, Microprosthema looensis, was taken from a single site in the Florida Keys. Microprosthema manningi is closely related to the western Atlantic M. semilaeve, while M. looensis is closely related to the Indo-Pacific M. scabricaudatum. However, both new species can be distinguished by numerous morphological differences, as well as by coloration.     

New records for hermatypic corals (Anthozoa: Scleractinia) in the Gulf of California,Mexico, with an historical and biogeographical discussion

This paper reports range extensions for seven hermatypic coral species in the Gulf of California. An analysis of the distribution and fossil record of the 12 hermatypic species of the Gulf shows that the coral communities of the Gulf are the oldest ones in the eastern Pacific. Two species have been recorded in the Gulf (or nearby) since the Pliocene and several other species since the Pleistocene. The uninterrupted fossil record falsifies the hypothesis of a total extinction of reef corals in the eastern Pacific during the Pleistocene. The fossil evidence and temperature calculations support the conjecture that the Gulf of California was a refuge zone for corals and other warm-water biotas during the same epoch. Also it is suggested that some species of the genera Porites may have an Atlantic origin, contrary to the accepted idea of an exclusive Indo-Pacific origin of the eastern Pacific coral fauna.     

On the fly fauna of the central region of the Kingdom of Saudi Arabia: new country records from Riyadh Region,with a list of associated fly species and zoogeographical remarks (Insecta: Diptera)

This study presents three genera and 10 species of flies (order: Diptera) as new country records from the Kingdom of Saudi Arabia (KSA). The flies were identified from Rawdhat Khorim National Park in Riyadh Region, the central region of KSA. The newly recorded genera are Glabellula (Mythicomyiidae), Phora (Phoridae) and Ceroptera (Sphaeroceridae), and the newly recorded species are Dilophus lingens (Bibionidae), Stichopogon deserti (Asilidae), Glabellula sp. (Mythicomyiidae), Phora sp. (Phoridae), Liriomyza lutea (Agromyzidae), Ceroptera aharonii (Sphaeroceridae), Trixoscelis deemingi, Trixoscelis migueli and Trixoscelis puncticornis (Trixoscelididae), and Physiphora leucotricha (Ulidiidae). Glabellula sp. and Phora sp. have been identified only to the genus level and are listed herein only because this is the first time they have been recorded in KSA, and additional specimens are required for their accurate identification to the species level. Also, this is the first record of Trixoscelis deemingi Wo?nica and Trixoscelis migueli Wo?nica from the Palaearctic Region. Distribution, diagnoses, remarks on biology and coloured photos are given for the recorded taxa. A list of associated fly species that were previously recorded in KSA and are identified from the study area in the present study is also presented. Zoogeographically, 33% of the identified fly species showed both Afrotropical and Palaearctic affinities, while 17% were of only Palaearctic affinity, and 8% were of only Afrotropical affinity. Elements from other regions were apparently nil. The results support the idea that the central Arabian Desert, which includes the present study area, is a transitional zone between the Palaearctic and Afrotropical regions.     

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.     

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.     

A new genus and species of Conchaspididae (Hemiptera: Coccoidea) from Florida,remarkable in lacking legs

A new genus of Conchaspididae, Asceloconchaspis gen. nov., is described for Asceloconchaspis milleri sp. nov., a new species from Florida, USA. Unlike other conchaspidids, the adult female and second instar of the genus lack legs. The presence of legs is one of the important, distinguishing characters at present separating the Conchaspididae from the Diaspididae. However, the new genus also possesses well-developed antennae and has multilocular disc pores on the abdomen in the adult female; these distinctly conchaspidid characters are never found in the Diaspididae. Asceloconchaspis is closely related to Fagisuga Lindinger, a monotypic genus with primitive characters described from South America on Nothofagus. A key to the four known genera of Conchaspididae is provided, and the morphology and distribution of the Conchaspididae are discussed.     

Notes on the classification of some little-known Australian paradoxosomatid genera (Diplopoda,Polydesmida)

Summary

The type species of six hitherto poorly described genera of Paradoxosomatidae from Australia have been re-examined. The name Cladethosoma Chamberlin, 1920, should replace Leucotessara Verhoeff, 1928; its type-species Australiosoma (C.) clarum Chamberlin, 1920, being conspecific with Leucotessara verhoeffi (Attems, 1931). The allocation of Somethus Chamberlin, 1920, and Paraustraliosoma Verhoeff, 1924, to the tribe Australiosomatini is confirmed. Australodesmus Chamberlin, 1920, formerly tentatively referred to the Australiosomatini, belongs to the Antichiropodini. The reference to the same tribe of Notodesmus Chamberlin, 1920, and Mjoebergodesmus Verhoeff, 1924, is substantiated.     

First record of the genus Koreanurina Najt and Weiner (Collembola: Neanuridae: Pseudachorutinae) from China,with description of two new species from Changbai mountain

The genus Koreanurina Najt and Weiner, 1992 is recorded for the first time from China. It is redefined and its similarity with the subfamily Caputanurininae is stressed. Two species are described from Changbai Mountain in North-East China: Koreanurina weinerae sp. nov. and K. alba sp. nov. The first species differs from the other species of the genus, mostly by its post-antennal organ located on the lateral edge of head (versus dorsolaterally), its central plate on head wider and the presence of only 1 + 1 chaetae on Th I (versus 2–3 + 2–3). K. alba sp. nov. differs from the other species of the genus mostly by the absence of body pigment, and the presence of only 1 + 1 chaetae posteriorly to the furcal rest (versus 2 + 2).

The generic affiliation of Japanese species of the subfamily Psyllinae (Hemiptera: Psyllidae) with a revised checklist

The generic affiliations of all the Japanese species of the psyllid subfamily Psyllinae are re-examined under the current generic recognition of the subfamily based mainly on adult morphological characters. Twenty-two species of the genus Psylla Geoffroy are newly combined with the genus Cacopsylla Ossiannilsson. Psylla wulinensis Yang and Aphalara akebiae Shinji are newly synonymized with Psylla multipunctata Miyatake and Cacopsylla hakonensis (Kuwayama), respectively. In addition, Cacopsylla toddaliae (Yang) is newly recorded from Japan. In all, 62 species of the Japanese Psyllinae are recognized and classified into three genera Psylla, Cacopsylla and Chamaepsylla Ossiannilsson, which include 11, 50 and one species, respectively. A key to Japanese psylline genera and a revised checklist of all the Japanese species of Psyllinae are presented with their distribution and host plant information and also with their synonymies.     

Aquatic Coleoptera from Pakistan: faunistic and zoogeographical contribution (Coleoptera: Gyrinidae: Dytiscidae: Hydrophilidae)

Records of 19 species and one subspecies of water beetles of four families: Gyrinidae (two species), Dytiscidae (seven species), Hydrophilidae (10 species), and Spercheidae (one subspecies) from Pakistan are listed, based on collected material. Four genera and 10 species are recorded from Pakistan for the first time. The newly recorded genera are: Patrus, Helochares, Sternolophus and Coelostoma. The newly recorded species are: Dineutus spinosus (Fabricius, 1781), Patrus haemorrhous (Régimbart, 1891), Copelatus freudei Guignot, 1955, Copelatus sp1, Copelatus sp2, Enochrus ater (Kuwert, 1888), Helochares anchoralis Sharp, 1890, Sternolophus rufipes (Fabricius, 1792), Paracymus aeneus (Germar, 1824) and Coelostoma stultum (Walker, 1858). Zoogeographic affinities of the recorded species are discussed. According to their current distribution, the 18 species known from Pakistan can be classified into five zoogeographical categories.
