Macrobrachium malayanum (Roux, 1934) stat. nov. (Decapoda,Palaemonidae) as a synonym of M. geron Holthuis, 1950, with notes on its distribution

Macrobrachium pilimanus malayanus (Roux, 1934) is synonymized with M. geron Holthuis, 1950 and accorded full species status as M. Malayanum (Roux, 1934) stat. nov. A lectotype is also designated. Variation within M. malayanum and differences between this species and M. pilimanus (De Man, 1879) are discussed, and the taxonomy of the species clarified. New records of M. malayanum are presented for Sarawak and Sumatra.     

Two new Oriental genera of Doryctinae (Hymenoptera,Braconidae) from termite nests

Two new genera of the subfamily Doryctinae collected in termite nests are described and illustrated: Termitospathius gen. n. from Sumatra (type species T. sumatranus sp. n.) and Ceylonspathius gen. n. from Sri Lanka (type species C. nixoni sp. n.). It is the first record of the braconids from termite nests in the Old World. The biological features of the Doryctinae species and phylogenetic positions of the new genera are discussed.     

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 Tho's (1982, 1992) unpublished new genus (Genus A) is considered to be a new species of Ceylonitermes.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.     

Cornutorogas,a new genus with four new species of the subfamily Rogadinae (Hymenoptera: Braconidae) from the Oriental region

A new genus, Cornutorogas gen. nov., and four new species, Cornutorogas orientalis Chen and Belokobyskij, sp. nov. (China, Vietnam), C. maetoi van Achterberg, sp. nov. (Thailand), C. javensis van Achterberg, sp. nov. (Java) and C. sumatrensis van Achterberg, sp. nov. (Sumatra), of the subfamily Rogadinae (Hymenoptera: Braconidae) from the Oriental Region are described and illustrated. The placement of this genus in the Rogadini is discussed.     

A remarkable new cave-dwelling Stylocellus (Opiliones,Cyphophthalmi) from peninsular Malaysia,with a discussion on taxonomic characters in the family Stylocellidae

A new opilionid species, Stylocellus globosus, is described from limestone caves near Ipoh (peninsular Malaysia). This is the third cave-dwelling species known in the genus Stylocellus; it shows various degrees of eye reduction and, due to the presence of anal glands in males, occupies a systematic position between the genera Stylocellus Westwood and Fangensis Rambla. Other characters, such as the presence of a smooth anal crest and details of gonopore complex of the penis, suggest relationship to Stylocellus sumatranus Westwood from Sumatra and to S. gryllospecus Shear from Borneo, respectively.     

Five new species of Monocelis Ehrenberg, 1831 (Platyhelminthes: Proseriata) from eastern Australia

Six species of the genus Monocelis Ehrenberg, 1831 have been found in eastern Australia. All are new to science. Five of them are formally described here. Three species (M. rupisrubrae sp. nov., M. nexilis sp. nov., and M. corallicola sp. nov.) have two clearly set pigmented eyespots lateral to the statocyst. They differ in details of the copulatory organ and karyotype. No clear synapomorphies among them or with other species of the genus could be detected. Monocelis beata sp. nov. and M. macrobulbus sp. nov. present extremely elongate, longitudinally oriented copulatory organs. They are sister species, and phylogenetic relationships with M. galapagoensis Ax and Ax, 1977 and M. hopkinsi Karling, 1966 are proposed. Australian Monocelis have distributions limited to recognized biogeographical provinces in eastern Australia: M. corallicola, M. beata and M. macrobulbus in the northern Australian Zone, M. rupisrubrae and M. nexilis in the ‘Overlap Zone’ of the central east coast and Monocelis sp. A in the southern Australian Region.     

The Indo-Australian and E. Palaearctic braconine wasp genus Euurobracon (Hymenoptera: Braconidae)

An illustrated key to the females of Euurobracon is provided. Three new species and two new subspecies are described: E. interstitialis sp. nov. from Malaysia; E. denticephalus sp. nov. from Dutch New Guinea; E. latitempus sp. nov. from New Guinea; E. cephalotes sumatranus ssp. nov. from Sumatra; impossibilis curticaudis ssp. nov. from Papua New Guinea. E. quadriceps var. apicalis Roman is raised to specific status. The following new synonyms are proposed: Euurobracon maculipennis (Cameron, 1910) (= E. triplagiata (Cameron, 1900)); E. melanospilus (Cameron, 1910) (= E. yokahamae (Dalla Torre, 1898)); E. merinotoides (Enderlein, 1920) (= E. forticornis (Cameron, 1905)); E. montivagus (Cameron, 1910) (= E. cephalotes cephalotes (Smith, 1858); stat. nov.); Collastes nigropectus (Cameron, 1911) (= E. yokahamae (Dalla Torre, 1898)). Two species are excluded from Euurobracon for the first time: E. nitidulus Brues, 1922 and E. mandibularis Brues, 1924. Each species of Euurobracon is fully described.     

African species of the mealybug genus Antonina Signoret (Hemiptera: Coccoidea: Pseudococcidae)

Four species of the legless mealybug genus Antonina have been recorded from Africa and are discussed here. These are A. graminis (Maskell), A. indica var. panica Hall, A. natalensis Brain and A. transvaalensis Brain. All are grass feeding species and live mainly at the base of the plants, between the leaf sheath or at the roots. The names A. indica var. panica and A. transvaalensis have been synonymized previously with A. natalensis but the three species are regarded here as distinct. A. indica var. panica is here raised to specific rank as A. panica. A. graminis is known world-wide, A. panica occurs in North Africa and extends into Israel and possibly Jordan, and A. natalensis and A. transvaalensis are known from the Afrotropical Region. All four species are redescribed and illustrated and a key is provided to aid identification.     

XVIII.—The Coleoptera of the Falkland Islands

Summary

A brief review of literature on central Indian Ocean Pseudochromidae is provided, followed by a key to central Indian Ocean species. Two new species, Chlidichthys inornatus and Pseudochromis dilectus, are described.     

The fifth element: reconnection of the disjunct distribution of the members of Siphonocryptida (Diplopoda) with the description of a new species from Nepal

The fifth species of the millipede order Siphonocryptida, Hirudicryptus quintumelementum sp. nov., is described from Nepal. With this, the surprisingly disjunct distribution of the order with its four former species from Sumatra, the Macaronesian Islands, Malaya and Taiwan, has become connected through the relatively young mountain chains of the Himalayas. The new species shows the typical morphology of the order, with very little variation in external characters (in lack of male specimens). This may be the result of the conservative evolutionary history of the surviving small, widely separated, remnant populations of a once coherent, ancient range. The female vulva of the new species is described, and illustrated for the first time in the order.     

First host records for the rogadine genera Rogasodes Chen and He and Canalirogas van Achterberg and Chen (Hymenoptera: Braconidae) with description of a new species and survey of mummy types within Rogadinae s. str.

The parasitic wasp genus Rogasodes is recorded for the first time outside mainland China, based on a new species, R. scytaloptericola Quicke and Shaw sp. nov., from Java. Rearing data and host remains associated with the type specimen show that it is a parasitoid of the palm‐feeding drepanid moth, Scytalopteryx elongata (Snellen). Canalirogas sp. aff. balgooyi van Achterberg and Chen is recorded from an unidentified lymantriid on clove trees in Indonesia (Sumatra) and illustrated. Both of these are the first host records for the genera. Rogas spilonotus Cameron is transferred to Canalirogas. A survey of mummy sclerotization and adult emergence holes in the subfamily Rogadinae sensu stricto is presented. The data suggest an early shift to a posterior emergence position, with a strictly dorsal position being largely characteristic of the common genus Aleiodes. Only Aleiodes and a few apparently closely related taxa, including Hemigyroneuron, typically form heavily sclerotized mummies.     

I.—Notes on the Natural History of East Finmark

Synopsis

A new species of Argyrophylax, parasitic on the Banana Scab-Moth Nacoleia octasema Meyrick, is described and the Oriental and Australasian species of this genus are reviewed; a key is given for their identification. Six species and a subspecies hitherto placed in other genera are here assigned to Argyrophylax, and seven new combinations are established; two specific names are newly placed in synonymy.     

A revision of Eumedonus H. Milne Edwards, 1834 and Gonatonotus White, 1847 (Crustacea: Decapoda: Brachyura: Eumedonidae), two genera of crabs symbiotic with sea urchins

The eumedonid genera Eumedonus H. Milne Edwards, 1834 and Gonatonotus White, 1847, are revised. Members of both genera are obligate symbionts with sea urchins. Eumedonus is separated from Gonatonotus mainly by the presence or absence of crests on the merus of the ambulatory legs. Eumedonus, as here defined, contains five species, viz. E. niger H. Milne Edwards, 1834 (type species), E. vicinus Rathbun, 1918, E. zebra Alcock, 1895, E. brevirhynchus n. sp., and E. intermedius n. sp. Gonatonotus, as here re-diagnosed, includes three species, viz. G. pentagonus White, 1847 (type species), G. granulosus (MacGilchrist, 1905), n. comb. and G. nasutus n. sp.     

On the genus Penthesilenula Rossetti and Martens, 1998 (Crustacea,Ostracoda, Darwinulidae) from (semi-) terrestrial habitats in São Paulo State (Brazil), with the description of a new species

Three species of darwinulid ostracods, belonging to the genus Penthesilenula, are reported from terrestrial and semi-terrestrial habitats in São Paulo State (Brazil). Penthesilenula reidae n. sp. is here described as new to science. It belongs to the africana-group in the genus and was found exclusively in bromeliad pouches. Penthesilenula aotearoa (in the incae-group) was previously known from New Zealand only and is here reported for the first time from South America. The third species, Penthesilenula brasiliensis, is here described from leaf litter in forests, constituting the first darwinulid taxon to be found in fully terrestrial habitats. The morphological diversity within P. brasiliensis s. l. is discussed and various lineages on different continents are retained within this species. The evolutionary significance of the high incidence of teratologies in the Darwinulidae is discussed. A tentative homology for the apical chaetotaxy of A2 between Darwinulidae and Cyprididae is offered.     

Genetic diversity of freshwater crabs (Brachyura: Sesarmidae) from central Jamaica with description of a new species

Jamaica is the only island of the Greater Antilles where freshwater streams are not populated by representatives of the old lineage of freshwater crabs, the Pseudothelphusidae. Instead, a very diverse fauna of endemic sesarmid crabs inhabits freshwater and terrestrial habitats throughout the island, thereby showing complete independence from the sea. They have been reported thriving in bromeliad leaf axils, rock rubble, empty snail shells, caves and mountain streams. Otherwise, the Sesarmidae are typical inhabitants of soft‐sediment littoral habitats like marshes and mangroves. For many years, crabs from Jamaican mountains streams had been considered to belong to a single species, Sesarma bidentatum Benedict . However, recent morphological and molecular studies have shown that crabs from mountain streams of different regions of the island belong to different species. Consequently, four new crab species have been described over the last 10 years. In this study, we give evidence that freshwater streams in central Jamaica also host two different species of crabs. In streams draining to the north we exclusively found the species S. windsor Türkay and Diesel, , while streams draining to the south were inhabited by a closely related but undescribed species of crab. The southern species is here described as new and is referred to as Sesarma meridies sp. n. Morphological and molecular (12S and 16S mtDNA) evidence is provided that allows these two species of freshwater crabs from central Jamaica to be distinguished. The species richness of Jamaican endemic sesarmids thereby increases to 10, which makes the island unique in terms of its diversity of land‐dwelling crabs.     

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.     

Report on the Raphitomidae Bellardi, 1875 (Mollusca: Gastropoda: Conoidea) from the China Seas

Twenty-seven Raphitomidae species belonging to nine genera, are recorded from the China Seas, including two new species, which are described here: Asperdaphne paramoretonica sp. nov., Daphnella inangulata sp. nov. Eight species are recorded for the first time from the China Seas.     

Revision of the type species of Metroperiella (Bryozoa,Cheilostomatida), with the description of two new species

We here fix the types of Schizoporella lepralioides Calvet in Jullien and Calvet, type species of the genus Metroperiella Canu & Bassler, and redescribe the species based on scanning electron microscope examination. Metroperiella populations from the Mediterranean Sea, which have hitherto been regarded as conspecific with Metroperiella lepralioides, are introduced as a new species, Metroperiella mesogeia sp. nov. Accordingly, the geographic distribution of M. lepralioides is restricted to its type locality, the Azores Archipelago (central North Atlantic). Another species, Metroperiella porellidesia sp. nov., which occurs sympatrically with M. lepralioides, is also newly described.
