LXV.—On an Encyrtid (Leefmansia bicolor,gen. et sp. n.) reared from eggs of Sexava (Orth.) in the Dutch East Indies

Summary

Eleven species of marine mites (Halacaroidea) are recorded from intertidal and subtidal collections made along the coast of California. Four new species Copidognathus spinifer sp. nov., Copidognathus ilsebartschi sp. nov., Agaue variabilis sp. nov., and Halacarus newelli sp. nov. are described. Agaue californica (Hall) is completely redescribed. Agauopsis newelli Krantz and Halacarus magniporus Krantz, new records for California, are diagnozed and described. Agauopsis curvata Krantz is diagnozed and further described. The juvenile stages of Copidognathus curtus Hall are described. The range of Agauopsis filirostris MacQuitty is extended within California. A tabular key to the Californian species of Copidognathus is given. The distribution of the halacaroids in California is compared to that of other fauna.     

“Typhloplanoida” (Platyhelminthes: Rhabdocoela) from the Indian Ocean,with the description of six new taxa

Seven typhloplanoids from the Indian Ocean are discussed; six of them are new to science. We place four of the new species within the Trigonostomidae. Gandalfia bilunata gen. nov. sp. nov. is characterized by a tubiform stylet and two semilunar structures in the afferent duct. Mahurubia clava gen. nov. sp. nov. has a gutter‐shaped stylet and a club‐shaped mouthpiece on the bursa. Parapharyngiella involucrum gen. nov. sp. nov. is characterized by a stylet in the form of a question mark and a bursal mouthpiece with a club‐shaped and a barrel‐shaped part. Poseidoplanella halleti gen. nov. sp. nov. is characterized by an unpaired ovary, a funnel‐shaped stylet connected with a plate, and a small, tubular bursal mouthpiece. Furthermore, new data are given on Ceratopera axi. The two other new species belong to the Typhloplanidae. Aegira annabellae gen. nov. sp. nov., a marine species, is characterized by a box‐shaped stylet and a long, pseudocuticularized ejaculatory duct. Castrada trispina sp., a freshwater species, has a copulatory bursa with three spines. Mahurubia clava gen. nov. sp. nov. and Parapharyngiella involucrum gen. nov. sp. nov. occur at Zanzibar, Tanzania. The other five species have been found on Kerguelen.     

Chinese psyllids in the genus Cacopsylla (Hemiptera: Sternorrhyncha: Psylloidea) associated with Spiraea (Rosaceae)

The Chinese Cacopsylla species associated with Spiraea are revised. Three new species (Cacopsylla falcata sp. nov., C. nocturna sp. nov. and C. qilianensis sp. nov.) are described, and two [C. hyalinonemae Li and Yang, 1989 and C. spiraeicola (Li, 2011) comb. nov.] are redescribed. A new combination is also proposed for Cacopsylla tetrotaenialis (Li and Yang, 1989) comb. nov. Among the five species, C. falcata and C. qilianensis are affirmed to develop on Spiraea, as fifth instar immatures were found. The host plants of the other species remain uncertain. Based on morphological grounds, it is suggested that C. falcata and C. nocturna are closely related, but that the five species associated with Spiraea do not constitute a monophyletic group.     

Synopsis of copepods associated with asteroid echinoderms,including new species from the Moluccas

Copepods associated with Asteroidea are listed, with their hosts and localities where found. Five new species and one new genus are included: Astericola carens sp. nov., Stellicola astrivagus sp. nov., Astroxynus choriasteris sp. nov., Chorioxynus moluccensis gen. nov., sp. nov., and Stellicomes bisphaerulifer sp. nov. New hosts and localities are recorded.     

Psocoptera of the Togo-Benin Gap,West Africa

Summary

The first major collection of Psocoptera from the Togo-Benin Gap containing 28 species, in 16 genera is described. Twelve of the species are new (Rhyopsocus plesiafer sp. nov., Caecilius propinquifallax sp. nov., C. fuscolineus sp. nov., Lachesilla mutabilis sp. nov., L. nigripalpa sp. nov., Ectopsocus maculosus sp. nov., Peripsocus marginatus sp. nov., P. acuminatus sp. nov., P. togoensis sp. nov., Pseudoscottiella forcipiforma sp. nov., Blaste togoensis sp. nov., and Trichadenotecnum colesae sp. nov.). Blaste muiri Smithers is synonymized with B. medleri New. The previously described psocid species, together with affinities which the new species have with the psocid fauna of other countries, are discussed in the light of the zoogeographical interest in this area.     

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.     

Two new species of the genus Sinella Brook, 1882 (Collembola: Entomobryidae) from East China

Two new species, Sinella hexaseta sp. nov. and Sinella pauciseta sp. nov., collected from East China, Anhui and Zhejiang provinces, respectively, were described. Both are easily discriminated from each other and all known Sinella species by their unique dorsocentral chaetotaxic patterns on Abd. IV. In S. pauciseta sp. nov., postlabial setae H_1–4 are ciliate, which are smooth in all other known species of the genus.     

A new species of freshwater crab (Decapoda: Brachyura: Potamidae) from Dongyin Island,Matsu, Taiwan,defined by morphological and molecular characters,with notes on its biogeography

A new species of freshwater crab, Nanhaipotamon dongyinense sp. nov. (Decapoda: Brachyura: Potamidae), is described from Dongyin Island, Matsu, Taiwan. Based on morphological and molecular (mitochondrial 16S rRNA) evidence, it can be distinguished from its congeners. The biogeography of the species, found on an island 50 km from mainland China, is also discussed.     

Scale insects of the families Asterolecaniidae and Eriococcidae (Hemiptera: Coccoidea) in New Caledonia

The scale insect families Asterolecaniidae and Eriococcidae are discussed from New Caledonia. One new genus Oacoccus gen. nov., and a new species Oacoccus nothofagi sp. nov. on Nothofagus sp., are described in the Asterolecaniidae, and a new species Eriococcus millei sp. nov. is described in the Eriococcidae. A new genus Rhopalotococcus gen. nov., and two new species Rhopalotococcus dugdalei sp. nov. and Rhopalotococcus metrosideri sp. nov., are also described in the Eriococcidae. Both species induce leaf galls on Metrosideros sp. Keys are provided for all the New Caledonian genera and species in the families Asterolecaniidae and Eriococcidae.     

Karkata,a new genus of gecarcinucid freshwater crab with two new species,and four new species of Pilarta Bahir and Yeo, 2007 and Cylindrotelphusa Alcock, 1909 (Decapoda: Brachyura) from Kerala,India

A new genus of freshwater crab, Karkata gen. nov., with two species, K. ghanarakta sp. nov. (type species) and K. kusumbha sp. nov., and two new species each of Pilarta Bahir and Yeo, 2007 (P. aroma sp. nov. and P. punctatissima sp. nov.) and Cylindrotelphusa Alcock, 1909 (C. breviphallus sp. nov. and C. longiphallus sp. nov.), are described from Kerala, India. Additionally, C. granulata (Pillai, 1951) comb. et stat. nov. is recognised as a distinct species. Karkata gen. nov. is distinguished from other Indian gecarcinucid genera by a suite of carapace and gonopod characters, including a moderately arched, smooth carapace, the presence of a prominent suture between male thoracic sternites 2, 3 and 3, 4, the absence of a flagellum on the third maxilliped exopod, a very short terminal segment of the male first gonopod (G1), and a short distal segment of the male second gonopod (G2). Karkata ghanarakta sp. nov. is differentiated from K. kusumbha sp. nov. by the shape of the G1 subterminal segment and its live colouration. Pilarta punctatissima sp. nov. is distinct among the congeners mainly by its densely punctate carapace, densely setose anterolateral and posterolateral margins of the carapace, stouter G1 terminal segment, and relatively long G2 distal segment whereas P. aroma sp. nov. can be separated from P. anuka Bahir and Yeo, 2007 by its relatively smooth carapace, deep H-shaped groove, relatively long G1 terminal segment, and almost straight outer margins of the G1 terminal and subterminal segments. Cylindrotelphusa breviphallus sp. nov. is differentiated from C. longiphallus sp. nov. and C. steniops (Alcock, 1909) by its stout G1, with a stout, short terminal segment. Cylindrotelphusa longiphallus sp. nov. is distinguished from the congeners by its shallow, narrow cervical grooves and relatively slender ambulatory legs. An identification key to the species of Karkata, Pilarta and Cylindrotelphusa is provided.

Annelids (Polychaeta and Oligochaeta) from the Sea of Marmara,with descriptions of five new species

This paper deals with annelids (Oligochaeta and Polychaeta) collected in the Sea of Marmara between 2006 and 2010 at depths from 0 to 66 m. A total of five oligochaete and 198 polychaete species were found. Five polychaete species, namely Prosphaerosyllis marmarae sp. nov., Levinsenia demiri sp. nov., Levinsenia kosswigi sp. nov., Levinsenia marmarensis sp. nov. and Levinsenia tribranchiata sp. nov. are new to science, and five oligochaete and 84 polychaete species are new to the fauna of the Sea of Marmara. A list of species found in the region and their maximum densities are presented at depth intervals. The present material includes six alien polychaete species, Paraprionospio coora, Polydora cornuta, Prionospio (Minuspio) pulchra, Pseudopolydora paucibranchiata, Chaetozone corona and Metasychis gotoi, of which the latter four species were new records for the region.     

Description of a new species of Demania Laurie, 1906 (Crustacea,Decapoda, Brachyura,Xanthidae) from the Bay of Bengal,Indian Ocean

A new species of xanthid crab, Demania bangladeshensis sp. nov., is described from the Bay of Bengal, Indian Ocean. Demania bangladeshensis appears to be most closely related to Demania toxica Garth, 1971, a poisonous species from the Philippines, but can easily be separated by the differently sculptured carapace, legs and chelipeds.     

New species of Australian arid zone chelonine wasps from the genera Phanerotoma and Ascogaster (Hymenoptera: Braconidae) informed by the ‘Bush Blitz’ surveys of national reserves

Here we focus on the poorly studied braconid wasp subfamily Cheloninae for the arid zone of the Australian continent, using material, in part, resulting from comprehensive surveys of three arid zone reserves. The Bush Blitz programme is a multi-institutional project with the aim of documenting the diversity of the flora and fauna in Australia’s National Reserve System, with describing new species being a key focus of the programme. In total, 11 species from the genera Ascogaster and Phanerotoma are treated, with species’ delimitation based on both molecular and morphological data. Two species are redescribed (Phanerotoma behriae Zettel, 1988a and P. decticauda Zettel, 1988a) and nine species are described as new (Ascogaster brevivena sp. nov., A. ferruginegaster sp. nov., A. prolixogaster sp. nov., A. rubriscapa sp. nov., Phanerotoma bonbonensis sp. nov., P. bushblitz sp. nov., P. lutea sp. nov., P. nigriscapulata sp. nov. and P. witchelinaensis sp. nov.). Keys to the arid zone species of these two genera are provided, along with a species richness estimation of Australian chelonine wasps.     

First record of the subfamily Coelotinae in Laos,with review of Coelotinae embolus morphology and description of seven new species from Laos and Vietnam (Araneae,Amaurobiidae)

First records of Coelotinae are reported from Laos. Five new species of the genus Draconarius are described from the northern Luang Nam Tha Province: Draconarius bounnami sp. nov. (male), D. latidens sp. nov. (female), D. postremus sp. nov. (male, female), D. songi sp. nov. (male) and D. tabularis sp. nov. (female). In addition, two new Coelotinae species are described from Vietnam: D. hanoiensis sp. nov. (female) and D. huongsonensis sp. nov. (female). Of the 429 currently valid Coelotinae species, 154 of them have only females described (36%). The embolus characteristics of those with males described (275 species, 64%) are reviewed. Two characters have been found that might be informative for the estimation of phylogeny, and their congruence with the current Coelotinae classification system is discussed. One character is the point from which the embolus arises and another is the embolus shape.

Illustrations of major diagnostic characters of the new species are given. A total of 33 species worldwide are placed into seven newly defined groups. A checklist of Sathytes is also provided.     

New taxa of the family Trochometridiidae (Acari: Heterostigmata) associated with insects from Iran

A new genus and two new species of mites of the family Trochometridiidae (Acari: Heterostigmata) are described from Iran: Neotrochometridium sensillum Hajiqanbar and Khaustov gen. nov., sp. nov. associated with two carabid beetles and Trochometridium iranicum Hajiqanbar and Khaustov sp. nov. associated with a halictid bee. We also present the first report of two previously described species. These findings provide the first record of the family Trochometridiidae from Iran. The chaetotaxy of tarsus I of the family is discussed and a key to world genera and species is provided.     

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.     

A new genus and three new species of free‐living marine nematodes from the Yellow Sea,China

One new genus, Paramphimonhystrella gen. nov., and three new species of free‐living marine nematodes in this genus, P. elegans sp. nov., P. minor sp. nov., and P. sinica sp. nov., are described and illustrated from the Yellow Sea, China. Paramphimonhystrella gen. nov. differs from the similar genus Amphimonhystrella by the elongated buccal cavity, cervical setae and large caudal glands. Paramphimonhystrella elegans sp. nov. is characterized by ovoid amphids and spicules with a small hook at distal end and cylindrical part of tail shorter than conical part. Paramphimonhystrella sinica sp. nov. is characterized by circular amphids, wide buccal cavity, spicules with blunt tip, and cylindrical part of tail longer than conical part. Paramphimonhystrella minor sp. nov. differs from the other two species by its smaller body (shorter than 800 µm), circular amphids, and spicules with sharp tip. The type species of this new genus is P. elegans gen. nov. and sp. nov. Types are deposited in the College of Marine Life Sciences, Ocean University of China.     

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.
