New species of Copidognathinae (Acari: Halacaridae) from southern Africa

Three new species of Copidognathinae (Acari: Halacaridae) are described from the eastern coast of southern Africa (Mozambique; South Africa: Eastern Cape and KwaZulu-Natal). Copidognathus caloglossae sp. nov. and Acarothrix umgenica sp. nov. were collected in mangrove habitats, whereas Copidognathus xaixaiensis sp. nov. was collected on a rocky shore. Acarothrix umgenica represents the first record of the genus Acarothrix Bartsch, 1990 from the African continent.     

African Derbidae (Homoptera,Fulgoroidea): taxonomic notes with descriptions of new species collected mainly from coconut

An annotated list of the African Derbidae described since Synave's 1973 monograph is given, with some corrections and additions to that work together with a revision of the genus Robigus from Africa. The following new species are described: Diostrombus schuilingi sp. nov., D. mkurangai sp. nov., Zorabana vipaku sp. nov., Patara minazi sp. nov., P. chambeziensis sp. nov., Paraphenice mawai, sp. nov., Phenice pongwei sp. nov., Robigus magawai sp. nov., Robigus synavei sp. nov. (= R. tortrinotatus sensu Synave, 1973), Kamendaka ukutu sp. nov. All of these new species with the exception of R. synavei were collected from coconut. The following new synonomies are made: Proutista fritillaris (Boheman) = P. tesselata (Westwood) syn. nov., Diostrombus abdominalis (Distant) = D. moerensis Synave syn. nov., Paraphenice dissimilis Synave = Pamendanga fuscinervis Van Stalle syn. nov., Zoraida fuligipennis Muir = Z. nigeriensis Synave syn. nov., Platocera africana Muir, omitted in error from Synave (1973), is described and figured. Proutista moesta (Westwood) is recorded from Africa for the first time.     

New earthworm species of the genus Pheretima (Clitellata: Megascolecidae) from Mountain Province,Philippines

Six new species of the genus Pheretima are described from Mt. Amuyao and Mt. Lamagan, near Barlig, Mountain Province, the Philippines: Pheretima tanudanensis sp. nov., Pheretima amuyaoensis sp. nov., Pheretima salcedoi sp. nov., Pheretima lamaganensis sp. nov., Pheretima julkai sp. nov., and Pheretima barligensis sp. nov. Pheretima tanudanensis sp. nov. has spermathecal pores in 6/7, 0.18–0.22 circumference ventrally apart, copulatory bursae openings 0.21–0.22 circumference apart, intestinal origin in XVI, and non-muscular spermathecal ducts. Pheretima amuyaoensis sp. nov. and Pheretima salcedoi sp. nov. have spermathecal pores in 5/6–6/7, a condition not previously known in the genus. Pheretima amuyaoensis sp. nov. has ventral spermathecal pores 0.23–0.24 circumference apart, copulatory bursae openings 0.23 circumference apart, and the intestinal origin in XVI. Pheretima salcedoi sp. nov. has ventral spermathecal pores 0.21–0.29 circumference apart, copulatory bursae openings 0.18–0.20 circumference apart, and the intestinal origin in XV. Pheretima lamaganensis sp. nov. and Pheretima julkai sp. nov. belong to the dubia group in Sims and Easton with three pairs of spermathecal pores in 6/7–8/9. Pheretima lamaganensis sp. nov. is a small-bodied worm with more setae in VII than in XX, two pairs of spermathecae in VII, one pair of spermathecae in VIII, ventral spermathecal pores 0.27–0.28 circumference apart and copulatory bursae openings 0.21–0.22 circumference apart. Pheretima julkai sp. nov. has two pairs of spermathecae in VII, one pair of spermathecae in VIII, ventral spermathecal pores 0.20–0.23 circumference apart and copulatory bursae openings 0.18–0.20 circumference apart, typhlosole lacking. One new earthworm, Pheretima barligensis sp. nov. belongs to the darnleiensis group with four pairs of spermathecal pores in 5/6–8/9, and has ventral spermathecal pores 0.16–0.22 circumference apart, copulatory bursae openings 0.19–0.22 circumference apart, an intestinal origin in XVI, and septa 8/9–9/10 present.     

Classification,reconstructed phylogeny and geographic history of the Neotropical phorid flies of the genus Gymnophora (Diptera: Phoridae)

The Neotropical species of Gymnophora are revised to include 28 species, 17 of which are new. Two subgenera, Cerocratia (in a revised sense) and Gymnophora s.s. are recognized. Cerocratia includes Gymnophora triangularis sp. nov., G. acutangula Schmitz, G. latibrachia sp. nov., G. lacertosa sp. nov., G. chilensis Borgmeier, G. parachilensis sp. nov., G. aemula Borgmeier, G. forticornis Schmitz, and doubtfully G. colona Brues. G. adumbrata Borgmeier is considered as a junior synonym of G. aemula (syn. nov.). Within Gymnophora s.s. there are four major lineages, the G. commotria-group, the G. carina-group, the G. cymatoneura-group and the G. quartomollis-group. Of these, the G. carina-group and the G. quartomollis-group are known only from the Holarctic Region. The G. commotria-group consists of the G. forcipis-series, containing G. forcipis sp. nov., subuncata sp. nov. and uncata sp. nov., and G. damula-series, whose species are further organized into the G. strigula-subseries, containing G. strigula sp. nov. and G. unidentata sp. nov., plus the G. falciformis-subseries, containing G. alces sp. nov., damula sp. nov. and falciformis sp. nov. Also included in the G. commotria-group are eight residual species whose relationships cannot be deduced at this time. Three of these species, G. commotria Schmitz, penai sp. nov. and quadrata sp. nov. are more closely related to each other than to G. auricula sp. nov., brasiliensis Borgmeier, heteroneura Schmitz, inusitata sp. nov. and trispina sp. nov. The G. cymatoneura-group contains G. cymatoneura Enderlein and G. spiracularis Borgmeier, and the male of G. spiracularis is described for the first time. A key is given that permits identification of males of most species, but females cannot be identified with certainty. A partially sequenced classification of the genus indicates the relationships of most of the included species. The genus may have originated in the Neotropical Region, although the evidence is tenuous, and shows some similarity of distribution to Andean-centered plant groups.     

A new species of the genus Cytheridella (Crustacea,Ostracoda) from Nigeria,West Africa

Cytheridella tepida sp. nov., a freshwater ostracod, is described from Nigeria, West Africa. It has been compared with five extant species of the genus Cytheridella. Cytheridella tepida was collected from slow-flowing streams characterized by warm water. Some other ecological notes on its habitat are given.     

Species of Oswaldella Stechow, 1919 (Cnidaria: Hydrozoa: Kirchenpaueriidae) from US Antarctic expeditions,with the description of three new species

Seventeen species of the genus Oswaldella Stechow have been studied, three of which are new to science (Oswaldella frigida sp. nov., O. medeae sp. nov. and O. monomammillata sp. nov.). The material studied was collected by several US Antarctic expeditions. Each species is described and figured, the systematic position amongst allied species is discussed and available data concerning autecology and geographical distribution are given. The remaining eight known species of the genus are also considered, regarding synonymy, autecology and geographical distribution. Finally, a general survey of the bathymetrical and biogeographical distribution of the known species of Oswaldella is given.     

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.     

A new genus and three new species of Phoridae (Diptera) parasitizing ants (Hymenoptera) in Sulawesi

Iridophora clarki gen. nov., sp. nov., Megaselia sembeli sp. nov. and M. kodongi sp. nov. are described. The females of I. clarki attack the workers of the ant Iridomyrmex cordatus (Smith). The same ant species is also attacked by M. sembeli, and the morphology of this species indicates that it is close to P. beirne Brues, the typespecies of the genus Plastophora. The loss of the type-material of the latter species prevented synonomy of the genus when it was re-evaluated (Disney, 1978). The detailed examination of M. sembeli now indicates that the genus Plastophora is a synonym of Megaselia (syn. nov.). A consequence is that P. dubitata Brues, 1935 becomes a homonym of M. dubitata (Malloch, 1912) and the replacement name M. bruesi nom. nov. is proposed. The females of M. kodongi attack workers of a species of Pheidologeton which forages on the forest floor. The habit of Iridomyrmex cordatus in using covered ways up trees appears to be related to its extreme vulnerability to attack by these two phorides.     

A new pontoniine shrimp (Crustacea: Decapoda: Palaemonidae) from the Ryukyu Islands,Japan

An unusual new genus and species of pontoniine shrimp, Nippontonia minirostris gen. nov., sp. nov., from a sponge host from the Ryukyu Is., Japan, is described and illustrated. The new genus appears not to be closely related to any of the previously described genera. The genus is particularly remarkable for the morphology of the fixed finger of the minor second pereiopod, which is without parallel in the Palaemonidae.     

Four new species of Platycephala with a key to the Chinese species (Diptera,Chloropidae)

The following four new species of the genus Platycephala from China are described: Platycephala apicinigra sp. nov., P. brevifemura sp. nov., P. lateralis sp. nov. and P. nanlingensis sp. nov. An updated key to the species of the genus Platycephala from China is presented.     

Two new palaemonid shrimps (Crustacea: Decapoda) from the Australian North West Shelf

Two palaemonid shrimps, from about 80 and 50 m on the Australian North West Shelf, are described and illustrated. A new genus, Carinopontonia, is designated for the single incomplete specimen of C. paucipes sp. nov. The new genus is most closely related to the genus Dasycaris Kemp, 1922. A single specimen of a second shrimp can be referred to Apopontonia Bruce, 1977, but to neither of the known species, and it is now described as A. tridentata sp. nov.     

Revision of the Madagascan genus Madecorphnus Paulian (Coleoptera: Scarabaeidae: Orphninae)

A scarab beetle genus, Madecorphnus Paulian, endemic to Madagascar, is revised. Nine new species are described: M. brunneus sp. nov., M. dentatus sp. nov., M. montreuili sp. nov., M. niger sp. nov., M. pauliani sp. nov., M. perinetensis sp. nov., M. peyrierasi sp. nov., M. punctatus sp. nov., M. simplex sp. nov. Diagnosis of the genus is clarified. Distribution map and a diagnostic key to all species are presented.     

The West Palaearctic species of Fidiobia Ashmead, 1894 (Hymenoptera: Platygastroidea)

One new genus Songmachilis and six new species in family Machilidae are described from China: Songmachilis xinxiangensis gen. sp. nov., Coreamachilis songi sp. nov., Pedetontinus jiuzhaiensis sp. nov., Pedetontinus maijiensis sp. nov., Pedetontinus taishanensis sp. nov. and. Pedetontinus wudangensis sp. nov. A key to all Chinese species of Pedetontinus is given. We also examined the relationships among Chinese machilids based on partial sequences of mitochondrial cytochrome c oxidase subunit I (COI). The molecular study further supported the species status of the six new taxa.     

Les espèces atlantiques du genre Eumunida Smith, 1883 (Crustacea: Decapoda: Chirostylidae)

Specimens of the genus Eumunida have been studied from various localities in the Atlantic Ocean. Comparisons of specimens from northwest and southwest Africa with material of E. picta from the western Atlantic Ocean has revealed two new species: E. bella nov. and E. squamifera sp. nov.

E. squamifera from the coast of Namibia, South West Africa, is distinguished from the two other atlantic species by a scaley striation of the carapace.

The northwest African E. bella and the western Atlantic E. picta, type of the genus, are closely related species, but differ from each other by the number and size of carapace marginal spines, shape of the anterior margin of the third thoracic sternum, and the ridges on the second abdominal segment. Their coloration is also different.

One specimen from the Tasman Sea identified by Gordon in 1930 as E. picta represents a further new taxon, E. australis sp. nov. It is readily distinguished from the three Atlantic species by the number of carapace anterio-lateral spines and the long acute projections of the third thoracic sternum.

All these species belong to the group A, as defined by Gordon (1930).     

Species of Staurotheca Allman, 1888 (Cnidaria: Hydrozoa: Sertulariidae) from US Antarctic expeditions,with the description of three new species

Seventeen species of the genus Staurotheca Allman have been studied, three of which are new to science (Staurotheca abyssalis sp. nov., S. densa sp. nov. and S. profunda sp. nov.). The material studied was collected by several US Antarctic expeditions. Each species is described and figured, the systematic position amongst allied species discussed and available data concerning autecology and geographical distribution given. The remaining six known species of the genus are also considered, regarding synonymy, autecology and geographical distribution. The type material of two poorly known species of Staurotheca, S. juncea (Vanhöffen) and S. pachyclada (Jäderholm) has been re-examined, re-described and figured. Finally, a general survey of the bathymetrical and biogeographical distribution of the known species of Staurotheca is given.     

Description of two new species of Guernea (Crustacea,Amphipoda, Dexaminidae) from Japan,with tentative revision of subfamily Prophliantinae

Guernea minor sp. nov. and G. ezoensis sp. nov. are described from Japan. Based on these new species and the literature, a tentative revision of the subfamily Prophliantinae is proposed. The subgenus Prinassus of the genus Guernea is invalidated. The subgenus Haustoriopsis of the genus Guernea is re-elevated to a separate genus from Guernea. Dexaminoculus is transferred from Prophliantinae to Dexamininae.     

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.     

New species of Dolichopus Latreille, 1796 from China (Diptera: Dolichopodidae)

The following three new species of Dolichopus are described from China: Dolichopus (Dolichopus) jilinensis sp. nov., D. (D.) longipilosus sp. nov. and D. (D.) yangi sp. nov. Three new species are reported from China, and a key to the Chinese species of the genus Dolichopus is presented for the first time.
