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.     

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.     

The taxonomy and biology of the Polystomatidae (Monogenea) in Australian freshwater turtles (Chelidae,Pleurodira)

Polystomoides scottae n. sp. is described from the urinary and accessory bladders of Chelodina expansa. Four species of Neopolystoma are described from the conjunctival sacs of Australian freshwater turtles (Chelidae): Neopolystoma cribbi n. sp. from Emydura signata, E. macquarii, Elseya latisternum and Chelodina expansa; Neopolystoma spratti n. sp. from Chelodina longicollis; Neopolystoma tinsleyi n. sp. from Chelodina expansa; and Neopolystoma queenslandensis n. sp. from Emydura signata and E. macquarii. Polystomoides australiensis, Neopolystoma macleayi and N. chelodinae are redescribed from new individuals. Neopolystoma australis is made a junior synonym of N. kreffti. P. australiensis, N. macleayi and N. cribbi produced on average 5·6, 4·3 and 0·7 eggs per day, respectively. Eggs of P. australiensis take 33–57 days at 18–24°C and 30–33 days at 24–28°C to develop and hatch. Oncomiracidia of P. australiensis and N. macleayi had 64 ciliated cells; the patterns of the ciliated cells are the same for both species. Different sizes of worms in different sites in the hosts suggest strongly that the oncomiracidia of P. australiensis and N. macleayi enter the host, migrate to the ureters, possibly to the kidneys, then to the urinary bladder and finally to either the accessory bladders or cloaca. Successful cross-infection experiments between host genera (Emydura to Elseya) indicated that P. australiensis and N. macleayi have a low degree of host specificity.     

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.     

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.     

The Australian species of Chromotydaeus Berlese and Penthaleus C. L. Koch (Acarina: Penthaleidae)

The Australian species of Chromotydaeus Berlese and Penthaleus C. L. Koch (Acarina: Penthaleidae) are revised. Chromotydaeus quartus n. sp. and Penthaleus falcatus n. sp. are described, and P. major (Dugés) and P. minor (Canestrini) redescribed. P. major is an agricultural pest, but all the other species appear to have no economic importance.

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.     

New species of Pauropodidae (Myriapoda: Pauropoda) from Nanjing,China

Six new species in the family Pauropodidae are described from China: Allopauropus disphaeroides sp. n., A. crassescens sp. n., A. apicalis sp. n., A. nanjingensis sp. n., Pauropus dorsappendix sp. n., and Stylopauropus zijinensis sp. n.     

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.     

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.     

New species of Isometopinae (Hemiptera: Miridae) from the Ivory Coast and Yemen

Myiomma cobbeni n. sp. and Paloniella nodifrons n. sp. are described from the Ivory Coast. Additionally, M. maculata n. sp., Isometopus yemenensis n. sp. and I. quadrivittatus n. sp. are described from the Republic of Yemen. The new species from Yemen represent the first records of Myiomma Puton and the subgenus Jehania Distant of Isometopus Fieber from the Middle East.     

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.     

Two new genera and five new species of the feather mite subfamily Proctophyllodinae (Astigmata: Proctophyllodidae) from suboscine birds in Brazil

Two new genera and five new species of feather mites of the family Proctophyllodidae are described from passerine birds from Brazil: Tyranniphyllodes pitangi gen. n., sp. n. from Pitangus sulphuratus (Tyrannidae); Atrichophyllodes delalandi gen. n., sp. n. from Corythopis delalandi (Tyrannidae); A. mentalis gen. n., sp. n. from Dysithamnus mentalis (Thamnophilidae); Anisophyllodes candango sp. n. from Elaenia chiriquensis (Tyrannidae); and Platyacarus sittasomi sp. n. from Sittasomus griseicapillus (Dendrocolaptidae). The discovery of these taxa might give data for a better understanding of the evolution of the family Proctophyllodidae in general and the dispersion of these mites on passerines in South America in paricular.     

Three new genera of Banchinae (Hymenoptera: Ichneumonidae) from Central and South America

Three new genera and four new species of Banchinae are described from Central and South America: Terrylee gen. n., is described from Peru and Honduras to accommodate Terrylee olearius sp. n. and Terrylee peruensis sp. n. (type species: Terrylee peruensis sp. n.); Valdiviglypta gen. n. and Pristiboea gen. n. are described from Chile (type species: Valdiviglypta nimbus sp. n. and Pristiboea leiomano sp. n.). Terrylee and Pristiboea are placed in the tribe Atrophini, Valdiviglypta tentatively in the tribe Glyptini. All the three new genera are morphologically very distinctive and two have such character suites that they may not immediately be recognizable as banchines. By describing these three Neotropical genera from Chile, Honduras and Peru we aim to draw further attention to the considerable morphological variation within the ichneumonid subfamily Banchinae.     

A revision of Tachyphron Brown and description of two new genera within the Ariphron group (Hymenoptera: Tiphiidae)

The Australasian genus Tachyphron Brown is revised, and two new New Guinean genera, Deuterothynnus gen. n. and Heligmothynnus gen. n., described. Fifteen species are included in Tachyphron of which seven are described as new (T. aculeatus sp. n., T. athertonensis sp. n., T. mantonensis sp. n., T. neosubfragilis sp. n., T. nigrisetatus sp. n., T. planus sp. n. and T. townsvillensis sp. n.), and a further two, Aelurus comatus Smith and Aelurus fragilis Smith, transferred from Tachynomyia. Thynnus insularis Smith is transferred from Tachynomyia Guérin to Deuterothynnus and a further three new species, D. fulvicentratus sp. n., D. fulvisetatus sp. n. and D. parallelus sp. n. described. Aelurus atratus Cameron and Takyomyia sabronensis Kimsey are transferred from Tachynomyia and Tachyphron, respectively, to Heligmothynnus and a further two new species, H. microspinus sp. n. and H. neoaratus sp. n. described. T. megacephala (Turner) is synonymized with Tachynoides flavopicta (Ritsema) and, therefore, removed from Tachyphron. A key to the Ariphron group of genera is provided, as well as keys to the males of Tachyphron, Deuterothynnus and Heligmothynnus, although the male of D. insularis is associated tentatively with the female holotype only on the basis of collection records. Only the females of D. insularis, T. armidalensis Brown and T. subtriangularus Brown are known, the latter two being described for the first time. Evidence is presented to suggest that T. subtriangularus may be bivoltine in northern Australia.     

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.     

The pygmaeus-group of Euops Schoenherr (Coleoptera,Curculionoidea, Attelabidae), weevils associated with Nothofagus in New Guinea

A new species group of Euops Schoenherr from the highlands of New Guinea is described and referred to as the ‘pygmaeus-group’. It is comprised of 14 species which, except for E. singularis VOSS, are described as new: E. anggiensis sp. n., E. bicolor sp. n., E. convexus sp. n., E. fraterculus sp. n., E. ibelensis sp. n., E. kurulu sp. n., E. nothofagi sp. n., E. parvus sp. n., E. paraconvexus sp. n., E. platyrostris sp. n., E. porulosus sp. n., E. pygmaeus sp. n., and E. sedlaceki sp. n.. Most of the species are of relatively small body size. They form a monophyletic group characterized by the synapomorphic loss of the ventral suture between the galea and palpifer of the maxilla. Two other groups are recognized, the eucalypti-group and the quadrifasciculatus-group. They are believed to be closely related to the pygmaeus-group and all three species groups together are referred to as the ‘pygmaeus-complex’. A cladistic analysis of the pygmaeus-group is performed. All species with host records are reported to feed on the fresh leaf flush of Nothofagus. This is the first record of a group of leaf-chewing arthropods restricted to the subgenus Brassospora of Nothofagus.     

New species of cryptognathid mites from Israel (Acari: Prostigmata: Cryptognathidae)

Favognathus gersoni n. sp. (from mosses), Favognathus cordylus n. sp. (from pine litter), and Cryptognathus attenuatus n. sp. (from tree bark) are described from Israel.     

Six new feather mite species (Acari: Astigmata) from the carolina parakeet Conuropsis carolinensis (Psittaciformes: Psittacidae), an extinct parrot of North America

We describe six new feather mite species collected from museum skins of the carolina parakeet Conuropsis carolinensis Linnaeus, 1758, which lived in North America and became extinct at the beginning of the 20th century: Genoprotolichus simplex sp. n., Lopharalichus beckeri sp. n., Neorhytidelasma conuropsis sp. n. (Pterolichidae: Pterolichinae), Chiasmalges carolinensis sp. n. (Psoroptoididae: Pandalurinae), Fainalges gracilitarsus sp. n., and Protonyssus proctorae sp. n. (Xolalgidae: Ingrassiinae). Brief comments on the current systematic state and host associations of these feather mite genera are provided.
