Poecilostomatoid Copepods from an Intertidal Mud Flat in the Yellow Sea

Thirteen new species and one new genus of poecilostomatoid copepods are described from intertidal mud flats in the central west coast of the Korean Peninsula facing the Yellow Sea. Nine species are found in association with invertebrates: Hemicyclops ventriplanus n. sp. from the decapod crustacean Upogebia major (De Haan); Clausia lobata n. sp. from the polychaete Marphysa sanguinea (Montagu); Presynaptiphilus minutus n. sp. from the ophiuroid Amphiura sinicola (Matsumoto); Synaptiphilus longicaudus n. sp. and Enterophilus cercomegalus n. gen. et n. sp. from the holothurian Protankyra bidentata (Woodward and Barrett); Goidelia pelliviva n. sp. from an echiuroid Thalassema sp.; Lichomolgus bullatus n. sp. from the bivalve Striarca (Didimacar) tenebrica (Reeve); Critomolgus nudus n. sp. from the pennatulacean Virgularia gustaviana (Herklots); and Notoxynus tertius n. sp. from the sea anemone Cerianthus filiformis Carlgren. The other four species are found in stagnant water on the mud flat: Kelleria vaga n. sp., Macrochiron anormalum n. sp., Pseudomacrochiron urostenum n. sp. and Pseudanthessius dentatus n. sp.     

Haematozoa of British birds. V. Redescription of Haemoproteus majoris (Laveran) from the great tit Parus major

Summary

Haemoproteus majoris, originally described by Laveran from Parus major in France but hitherto denied specific status, is redescribed from P. major in Great Britain and designated a valid species. H machlolophi de Mello (1935) of P. xanthogenys in India is considered to be a synonym of H. majoris. The occurrence and distribution of haemoproteids in other Paridae is briefly discussed.     

Life cycles of Phialella zappai n. sp., Phialella fragilis and Phialella sp. (Cnidaria,Leptomedusae, Phialellidae) from central California

The life cycles of three species of Philadella from central California (Phialella zappai n. sp., P. fragilis and P. sp.) are described. The three species have similar hydroids, with similar ecology. The medusae are very distinctive in both morphology and biology. Phialella sp. is delicate and difficult to rear; P. fragilis has a limited growth; and P. zappai shows precocious gonad maturation and continuous growth, with the possibility of becoming sexually mature more than once in its life. An interpretation of these phenomena suggests that the hydroids are basic, less varied, larval stages, as the medusae are the adults.     

New taxa of Rhagidiidae (Acari: Prostigmata) from North America. Part V. Genus Robustocheles Zacharda,with a key to world species of the genus

Six new species of rhagidiid mites from the Nearctic region, Robustocheles (R.) pascuaria n.sp., R. (R.) similis n.sp., R. (Mexia) longichelae n.subgen, n.sp., R. (Lewia) lacustris n. sp., R. (L.) obscuritata n. sp. and R. (L.) spinaea n. sp., are described. Additional morphological data are given for R. infernalis Zacharda and Elliott which is placed in the new subgenus Mexia. A key to adults of the known four subgenera and 15 species of the genus Robustocheles Zacharda of the world is presented.     

Jumping plant‐lice of the family Phacopteronidae (Hemiptera: Psylloidea) from Cameroon

Nine species of the family Phacopteronidae are recorded from Cameroon. All are assigned to the large pan‐tropical genus Pseudophacopteron. Eight species are described as new, and P. electum Capener is redescribed. The species are diagnosed and illustrated, and keys for the identification of adults and fifth instar larvae are provided. Information is given on distribution, host plants, and biology. Eight species are associated with plants of the order Rutales/Sapindales (three Sapindaceae, one Burseraceae, one Burseraceae or Anacardiaceae, one Meliaceae, one Rutaceae, and one Anacardiaceae/Simaroubaceae); host plants of one species remain unknown. Four species, namely P. electum, P. fuscivenosum sp. n., P. lecaniodisci sp. n., and P. morion sp. n., induce nut or pit galls on the leaves.     

Phorbas posidoni n.sp. (Porifera: Poecilosclerida) from the Aegean Sea,with a discussion of the family Anchinoidae

A new species of the genus Phorbas Duchassaing and Michelotti, 1864 (junior synonym Anchinoe Gray, 1867) is described from the Aegean Sea (Eastern Mediterranean). Phorbas posidoni n.sp. is distinguished from the known Mediterranean species of Phorbas primarily by its elaborate repent-ramose habit combined with an extensive, spongin-enforced, plumoreticulate skeleton of oxea-like tornotes and the usual echinating acanthostyles and arcuate chelae. As in most Phorbas the surface bears characteristic areolae. The only other elaborate Mediterranean species, P. mercator (Schmidt) differs clearly in spiculation, since it lacks microscleres and has strongyles as the main skeletal elements. Phorbas fictitius (Bowerbank), P. tenacior (Topsent) and P. paupertas sensu Topsent are all incrusting and differ in spicule form and sizes as well. Likewise, Phorbas species from the neighbouring East Atlantic each show clear differences with P. posidoni n.sp. The genus Phorbas is discussed and compared with Pronax Gray (1867) sensu Lévi (1973). It is proposed to unite the two genera because the alleged sharp difference between the two (only oxea-like tornotes in the skeletal tracts in Phorbas, only acanthostyles in the skeletal tracts in Pronax) is compromised by a range of intermediate conditions in various species.     

Three new species of Pseudohaliotrema Yamaguti, 1953 (Monogenea: Ancyrocephalidae) from Siganus species (Siganidae) and the description of a mechanism for cross-insemination

Three new species of Pseudohaliotrema Yamaguti, 1953 were collected from two Siganus species caught off Singapore. They are Pseudohaliotrema virgata n. sp. and P. molnari n. sp. from Siganus virgatus and P. falcata n. sp. from S. guttatus. They differ in the shape and size of both the body and haptoral sclerites and in the morphology of the male organ (modified copulatory organ). Pseudohaliotrema species from siganids are characterized by having a large prominent vaginal pouch, an eversible spermatophore transfer tube associated with the vaginal pouch, ovoid spermatophores (in mature worms), a male organ adapted for spermatophore formation, a large prostatic reservoir, and a testis and ovary arranged side by side. Pseudohaliotrema plectocirra Paperna, 1972 is re-assigned as Tetrancistrum plectocirra (Paperna, 1972) n. comb. Pseudohaliotrema species from non-siganid fish do not possess these characteristics and belong elsewhere. The generic diagnosis of Pseudohaliotrema is amended. Pseudohaliotrema species use a spermatophore for sperm transfer, which is documented in detail for P. virgata n. sp. The same reproductive strategy is used by P. molnari n. sp. and P. falcata n. sp., as indicated by the presence of spermatophores on the spermatophore transfer tube and inside the vaginal pouch. The presence of individuals exchanging spermatophores indicates that P. sphincteroporus Yamaguti, 1953 and P. sigani Yamaguti, 1953 also employ the same mechanism. The spermatophore, assembled in the sclerotized male organ and stored in the spermatophore chamber, is retrieved by the eversible spermatophore transfer tube (housed within the vaginal pouch) and drawn into the vaginal pouch as the spermatophore transfer tube invaginates. Within the vaginal pouch, the wall of the spermatophore disintegrates releasing spermatozoa.     

The Agromyzid genus Paraphytomyza Enderlein: new to the Oriental Region (Diptera)

Paraphytomyza jasmini sp. n. from India and P. loniceroides sp. n. from N.W. Pakistan are described, representing the first reared species in this genus known in the Oriental Region. P. kraussi (Sasakawa, 1963) from Papua New Guinea is formally transferred to Paraphytomyza as a new combination. The nomenclature, distribution and host range of Paraphytomyza are discussed.     

Weevil (Coleoptera: Curculionoidea) seed-predators of Syzygium and Eugenia spp. (Myrtaceae), with description of the Alcidodes expansitarsis species group (Coleoptera: Curculionidae: Molytinae: Mecysolobini)

The weevils known to develop in Syzygium and Eugenia (Myrtaceae) fruit are reviewed. These weevils belong to the genera Curculio, Alcidodes, Acythopeus, Apotomorhinus (Curculionidae: Curculioninae, Molytinae and (the last two) Baridinae respectively) and Sitophilus (Dryophthoridae) in the Old World, and Atractomerus (Curculionidae: Anthonominae) in the Neotropics; two undescribed baridine species (one in Australia and the other in the USA) are also known to feed on the fruits, and the Omophorine Teleuropus (Curculionidae: Molytinae) has been found associated with them. Particular attention is paid to species of Alcidodes from aseasonal dipterocarp-dominated forests in South-East Asia. Two Bornean species (Alcidodes janetae sp. n. and A. eugeniophilus sp. n.) are the first of their genus to be reared from the fruit of Syzygium or Eugenia. These species, plus two other (A. expansitarsis sp. n. from Assam, Myanmar, Cambodia and Laos, and A. gymnasticus sp. n. from Malaysia) belong to a previously undescribed species group of Alcidodes; all four species are described and keyed.     

First collections of water mites (Acari: Hydrachnidia) from Honduras: descriptions of six new species

First collections of water mites (Acari: Hydrachnidia) from Honduras indicate a rich fauna. Nineteen species from just three sites yielded six species new to science. New species described and discussed are: Hydrodroma moralesi n. sp., Flabellifrontipoda triscutata n. sp., Monatractides angelae n. sp., Pseudotorrenticola espinasseae n. sp., Atractides jenniferae n. sp. and Recifella cusucoensis n. sp.     

New species of Doliodrilus and other Limnodriloidinae (Oligochaeta,Tubificidae) from Hainan and other parts of the north-west Pacific Ocean

Thirteen species of Limnodriloidinae (Tubificidae) are recorded from marine and brackish-water habitats of Hainan Island, southern China, including 11 species of Doliodrilus and two species belonging to Limnodriloides. Eight species are new to science: D. bisaccus sp. n. (types from Japan), D. longidentatus sp. n. (types from Hong Kong), D. ciliatus sp. n., D. adiacens sp. n., D. fibrisaccus sp. n. (also from Fiji), D. brachyductus sp. n., D. bidolium sp. n. and D. chinensis sp. n. In addition, material of D. puertoricensis Erséus and Milligan, 1988, from New Caledonia, is briefly described. This study shows that Doliodrilus is unexpectedly species-rich in Asian seas, in particular, around Hainan. Including an unnamed species from this island, the known members of this genus increase from three to 12.     

Six new species of Microstigmus wasps (Hymenoptera: Sphecidae), with notes on their biology

Six new species of Microstigmus are described and illustrated. Nests and other aspects of their biology, when known, are also described. Microstigmus puncticeps sp. n. (northern Brazil and Peru) and M. xanthosceles sp. n. (Central America and western Colombia) belong to two distinct groups not closely related to previously described species. Microstigmus cooperi sp. n. and M. crucifex sp. n. (both from northern Brazil and Colombia) represent basal lineages within the large group including M. brasiliensis, M. theridii, M. lobifex, etc. Microstigmus flavus sp. n. (southeastern Brazil) is closely related to M. lobifex. Microstigmus simplex sp. n. (northern Brazil) is a basal lineage within the group containing M. guianensis and M. arlei. Reuse of nests of M. nigrophthalmus by M. flavus sp. n. and of M. crucifex sp. n. by a species of the M. theridii complex is reported for the first time for Microstigmus.     

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.     

Nine new species of Braconidae (Hymenoptera) from the Russian Far East

Nine new species of Braconidae from the Russian Far East are described and illustrated: Tebennotoma spasskensis sp. n., Parahormius bikinus sp. n., Colastes (Colastes) ussuricus sp. n., C. (Shawiana) kurilensis sp. n., C. (S.) bohayicus sp. n., Oncophanes makarkini sp. n., Doryctes slavianka sp. n., Brulleia chankaica sp. n., Cardiochiles turga sp. n. The genera Tebennotoma Enderlein and Brulleia Szépligeti are recorded for the Russian fauna for the first time.     

Psocoptera (Insecta) from Bermuda

Seventeen species of Psocoptera are recorded from Bermuda, increasing the known number from three. Four new species are described: Echmepteryx atlantica n. sp., Caecilius bermudensis n. sp., Indiopsocus hilburni n. sp., and I. nebulosus n. sp. The latter two species appear to be closely related and two alternative hypotheses are proposed for their origin. Ectopsocus spilotus Thornton and Wong is recorded outside the central Pacific area for the first time. The species are assigned to four categories according to probable duration of time on Bermuda and probable source of original invaders: (1) endemics (four species); (2) species with wide distributions in the tropics and subtropics, not restricted to islands and sea coasts (four species); (3) species largely restricted to sea coasts and islands, not necessarily tropical (three species); (4) species widely distributed in southeastern United States, not restricted to the sea coast or the subtropical region (five species).     

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.     

Taxonomic review of a new genus,Diathera gen. n., from Southeast Asia (Lepidoptera,Geometridae: Larentiinae)

Diathera gen. n., a new larentiine genus from central and southwestern China, is described. Three new species are named and described: fluctuata sp. n., metacolorata sp. n. and brunneata sp. n. All species and their genitalia are described and illustrated. A key is provided and the monophyly of the genus and its relationships to the allied taxa are briefly discussed.     

A study on amphipods from the superfamily Stegocephaloidea Dana 1852 from the northeastern Pacific region: systematics and distributional ecology

Nine species (including five new to science) of non-lafystiid stegocephaloid amphipods have been recognized within the collections of the Canadian Museum of Nature from the NE Pacific (Alaska to Oregon), viz. Acanthonotozoma rusanovae Bryazgin 1974 (Acanthonotozomatidae), Iphimedia rickettsi Shoemaker 1931 (Iphimediidae), Parandania boecki (Stebbing 1888), Phippsiella cascadiensis n.sp., Stegocephalexia penelope n. gen., n. sp., Stegocephalopsis mamillidacta n. sp. (Stegocephalidae). Odius kelleri Bruggen 1907 is reallocated to Cryptodius n. gen., and C. unguidactylus n. sp. and Imbrexodius oclairi n. gen., n. sp. (Odiidae) are also described. Keys are presented which allow the genera of Odiidae of the world, and of this collection of species, to be distinguished.     

Harpacticoid copepods (Thalestridae) infesting the cultivated Wakame (brown alga,Undaria pinnatifida) in Korea

Two species of thalestrid harpacticoid: Amenophia orientalis n. sp. and Parathalestris infestus n. sp., are described based on specimens collected from Soando Island in Korea. These copepods infest the cultivated brown alga, Wakame, Undaria pinnatifida (Harvey), producing galls with pinholes (0·5–1·1.5 mm in diameter) on the fronds, midribs, and sporophylls. A. orientalis outnumbered P. infestus in all of the observed incidences; however, the fecundity of the latter species is twice that of the former.     

Heterotrophic flagellates (Protista) from marine sediments of Botany Bay,Australia

Heterotrophic flagellates (protozoa) occurring in the marine sediments at Botany Bay, Australia are reported. Among the 87 species from 43 genera encountered in this survey are 13 new taxa: Cercomonas granulatus n. sp., Clautriavia cavus n. sp., Heteronema larseni n. sp., Notosolenus adamas n. sp., Notosolenus brothernis n. sp., Notosolenus hemicircularis n. sp., Notosolenus lashue n. sp., Notosolenus pyriforme n. sp., Petalomonas intortus n. sp., Petalomonas iugosus n. sp., Petalomonas labrum n. sp., Petalomonas planus n. sp. and Petalomonas virgatus n. sp.; and seven new combinations, Carpediemonas bialata n. comb., Dinema platysomum n. comb., Petalomonas calycimonoides nom. nov., Petalomonas christeni nom. nov., Petalomonas physaloides n. comb., Petalomonas quinquecarinata n. comb. and Petalomonas spinifera n. comb. Most flagellates described here appear to be cosmopolitan. We are unable to assess if the new species are endemic because of the lack of intensive studies elsewhere.
