The male of Lecane bulla (Gosse, 1851): new support for the synonymy of Lecane Nitzsch,Monostyla Ehrenberg and Hemimonostyla Bartos

The hitherto unknown male of Lecane bulla (Gosse, 1851) is described and figured. It is generally similar to the few known males of other Lecane species. However, whereas the degree of fusion of the toes accords between male and female in other species, this is not the case here: the male of L. bulla has two separate and movable toes, these are completely fused into a single toe in the female. This observation further questions the validity of the taxonomic separation of Lecane in three taxa of generic rank, based on the degree of fusion of the toes. The behaviour and reproduction of Lecane is commented upon.     

A revision of the Fabriciin genus Augeneriella Banse, 1957 (Polychaeta: Sabellidae)

The Sabellidae polychaete genus Augeneriella Banse is revised based on a reexamination of the type material of most species. Augeneriella hummelincki hummelincki Banse is shown to have vascularized, ventral filamentous appendages which can display up to four branches in a pectinate arrangement, as opposed to only a single dichotomy as originally described. The status of A. hummelincki indica Banse is discussed. The species A. bansei Hartmann-Schröder is based on a single, probably aberrant, specimen in which ventral filamentous appendages are unbranched. Additional material will likely show that this species displays the typical branched condition for ventral filaments. Augeneriella dubia Hartmann-Schröder can be ascribed to an undescribed genus which has been found in Atlantic, Indian, and Pacific Oceans. Two new species of Augeneriella from the Aldabra Atoll, Indian Ocean, are described.     

A review of the genus Parapenaeon Richardson, 1904 (Crustacea: Isopoda: Bopyridae: Orbioninae), with description of three new species from China

Five species of the bopyrid genus Parapenaeon are reported from China, of which three are new to science, and one, Parapenaeon expansa Bourdon, 1979, is a new record. New species are Parapenaeon calculosa, sp. nov., Parapenaeon diatropa, sp. nov. and Parapenaeon sicyoniae, sp. nov., from the East and South China Seas. The female of each new species has six pleomeres, no lateral plates on the sixth pleomere, and biramous uropods, characters that place them in the genus Parapenaeon Richardson, 1904. Each can be distinguished from previously described species of the genus Parapenaeon in body shape, by the characters of oostegite 1, the barbula, brood pouch, pleopods and uropods of the females. A table including all of the currently recognized species of Parapenaeon with type localities, known geographical distribution and reported hosts, is given. A key to the recorded species of Parapenaeon Richardson, 1904 is provided, as is a new diagnosis of the genus.

On some aradid bugs described by Francis Walker (Insecta: Hemiptera)

Brachyrhynchus fulvicornis Walker is synonymized with Arictus tagalicus Stål; Mezira humilis Walker is transferred to the genus Neuroctenus and luteomaculatus Kormilev & Heiss is synonymized with it; a new species Carventus dollingi is described from New Guinea, based upon a specimen misidentified by Distant as the type of Mezira ferrea Walker.     

Taxonomic notes on the Asian frogs of the tribe Paini (Ranidae,Dicroglossinae): 1. Morphology and synonymy of Chaparana aenea (Smith, 1922), with proposal of a new statistical method for testing homogeneity of small samples

The species from northern Vietnam described as Rana fansipani Bourret, is shown to be a synonym of the species from northern Thailand described as Rana aenea Smith, . The male secondary sex characters of this species are described in detail for the first time. Combined with a few other characters, they allow this species to be distinguished from the closely related Rana unculuanus Liu, Hu and Yang, 1960 from southern China. Both species should be placed in a subgenus Chaparana (Chaparana), a member of the tribe Paini of the subfamily Dicroglossinae of the Ranidae. In this study, we propose a new statistical method for testing homogeneity of small samples: this consists of considering the values obtained for each specimen and for each regression factor score as morphometric characteristics of this specimen within the frame of this analysis; these values, or some of them, can be used to compare subgroups of specimens by non‐parametric tests such as the Mann–Whitney U test.     

On the systematics,distribution and conservation status of Ichthyophis longicephalus Pillai, 1986 (Amphibia: Gymnophiona: Ichthyophiidae)

The caecilian Ichthyophis longicephalus was described in 1986 based on a single specimen. Only one specimen has been referred subsequently to this species, and the validity of that referral has been questioned. Seven specimens discovered in 2009–2010 at two new localities and two specimens collected in 1990 from a third locality are referred here to I. longicephalus. These specimens are described and compared with the poorly preserved holotype. Mitochondrial DNA data are consistent with the interpretation that the new specimens represent a single species distinct from (and most closely related to I. tricolor among) sampled congeners. The previously referred specimen, from c. 320 km south of the type locality, is not I. longicephalus and probably represents an undescribed species. The “rediscovery” of I. longicephalus in forests and disturbed habitats indicates that the species probably could be transferred from the Data Deficient to the Least Concern category of the IUCN Red List.     

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.     

Systematics of the Protohermes parcus species group (Megaloptera: Corydalidae), with notes on its phylogeny and biogeography

A species group, the Protohermes parcus group of the dobsonfly genus Protohermes, is proposed by the unique male genitalic structures. Five species belonging to the proposed species group from China and Nepal are described and illustrated, including three species new to science. A cladistic analysis is conducted to reconstruct the interspecific phylogeny within the proposed species group based on the morphological data. The biogeography of the proposed species group is also discussed.     

Two new species of Calima Moreno-González and Villarreal, 2012 (Arachnida: Schizomida: Hubbardiidae) from the Colombian Andes,with a discussion on the male flagellar microsetae of Hubbardiinae

Two new species of short-tailed whip-scorpions (schizomids), Calima embera sp. nov. and Calima nutabe sp. nov. are described based upon collected material from the Natural Park Planes de San Rafael, Risaralda department, and the Natural Reserve El Romeral, Antioquia department, Colombia, increasing the number of known species for the genus to four; an identification key and a distribution map for Calima species, are provided. The voluminous spermathecal lobes in females and the presence of a small dorsal eminence basal to Dm4 in the male flagellum of some species, could represent diagnostic characters for Calima and are therefore included in its diagnosis. The microsetae of the male flagellum of Hubbardiinae, continues be excluded from the setal homologies; we suggest that they must be taken into consideration in a future homology proposal. www.zoobank.org/urn:lsid:zoobank.org:pub:1D3A97A4-29A6-46E2-AD78-EE6C7036D251     

Mating behaviour in the bees,Dieunomia heteropoda and Nomia tetrazonata,with a review of courtship in Nomiinae (Hymenoptera: Halictidae)

Males of many bees in the subfamily Nomiinae (Halictidae) have numerous secondary sexual characters, which provide much systematic information. Similarly, the use of these structures by males during sexual behaviour may provide useful characters, but the courtship and copulatory behaviour of most of these bees is not known. Structures and behaviour used for courtship and mating are described for two species of nomiine bees, Dieunomia heteropoda and Nomia tetrazonata, along with brief observations of mating in a parasitic bee, Triepeolus verbesinae (Apidae: Nomadinae). A review of mating behaviour within the Nomiinae shows no obvious phyletic patterns, based upon present limited knowledge. The species-specific nature of the male secondary sexual characters suggests they may have evolved in the context of sexual selection, but behavioural data from populations of additional species are needed to evaluate the hypothesis adequately.     

Indirect and direct acoustic aggression in cicadas: first observations in the Palaearctic genus Tibicina Amyot (Hemiptera: Cicadomorpha: Cicadidae)

Tibicina Amyot is a cicada genus of the Palaearctic biogeographical region with seven taxa (species and subspecies) distributed in France. As in other cicadas, the sound production by tymbal vibration is restricted to males. In Tibicina, males are attracted by conspecific calling songs and tend to form groups of several individuals which maintain a minimal distance between each other. Observations based upon male–male interactions in such aggregations and on some preliminary experiments conducted with males kept in captivity revealed for the first time both indirect and direct aggression. Spacing and chorusing are interpreted as a by-product of indirect aggression mediated through the calling song. Direct aggression occurred when spacing is not respected. It is achieved through a ritualistic sequence that involves mainly the production of the rivalry song, an acoustic signal previously reported in the literature for two cicada species only. In addition, satellite males and male–male courting are reported. These preliminary results suggest that the sound social organization in the genus Tibicina is more elaborate than first suspected and should be reconsidered in terms of lek behaviour and sexual selection.     

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 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.     

A new species of marine nemertean from Anglesey,North Wales,with a discussion of the genus Paroerstedia Friedrich, 1955

A new species of marine nemertean, Paroerstedia nigrimaculata sp. nov., is described and illustrated from a single specimen found among Corallina in a lower shore rock pool at Rhosneigr, Anglesey, North Wales. No Paroerstedia species has been recorded previously from the British Isles. The systematics of the genus and its contained species are discussed.     

A revision of the Asian and European species in the subgenus Amiota Loew (Diptera,Drosophilidae) and the establishment of species-groups based on phylogenetic analysis

A total of 53 Amiota (s. str.) species (75% of the world total) from Asia and Europe, including 10 new species, kamui, kimurai and planata from Japan, and aristata, cuii, macai, magniflava, nuerhachii, spinata and watabei from China, are reviewed with designation of two new synonymies and phylogenetic analysis. Based upon the result of cladistic analysis with 31 adult male morphological characters, the following conclusions are deduced: (1) The subgenus Amiota is monophyletic, so far as the Asian and European forms are concerned. (2) Seven monophyletic groups are recognized within this subgenus. Two of them correspond to known species-groups, the apodemata and sinuata groups, and the remaining five are established as new species-groups, the nagatai, basdeni, taurusata, alboguttata and rufescens groups. A key to all the studied species from Asia and Europe is provided.     

On the occurrence of blood flukes (Sanguinicolidae: Trematoda) in British freshwater fish

Summary

A new genus, Cahara, is described, based upon Dalpada brevivitta Walker, as its type species C. brevivitta (Walker) comb. nov., C. confusa (Distant) comb. nov. and C. jugatoria (Lethierry) comb. nov. are redescribed and illustrated. C. murreeana sp. nov., C. montana sp. nov., C. kightleyi sp. nov., C. chaubattia sp. nov., C. bhowaliana sp. nov. and C. metallica sp. nov. are described as new. The genus Cahara occurs in the subhimalayan region of India, Pakistan and Nepal. Its members feed on deciduous trees, apple, walnut, fir, deodar, Bauhinia, etc. Superficially, the species resemble one another, as well as members of Dalpada s. lat. in their coloration and some have been confused with species like Dalpada versicolor in the past, but certain characters, like the shape of the head, the simple second antennal segment and more particularly the male and female genitalia, distinguish the genus Cahara from all others. A key to the species of Cahara is provided.     

Two new South American species of Acrobelus Stål (Hemiptera: Cicadellidae: Cicadellinae) with a key to the species of the genus

Two new leafhopper species of the Neotropical genus Acrobelus Stål, 1869 are described and illustrated: A. nessimiani sp. nov. from Peru (Amazonas Department) and A. rakitovi sp. nov. from Ecuador (Orellana Province). The two new species, distinguished from the other Acrobelus species by their remarkably long male subgenital plates and by the fusiform macrosetae present on these plates, seem to be closely related. A key to male specimens of the five known species of Acrobelus is provided. Taxonomic notes on the genus are included.     

Three noteworthy mirine plant bugs inhabiting subalpine zones of the Nepalese Himalayas (Hemiptera: Heteroptera: Miridae: Mirinae)

Three unique mirine plant bugs inhabiting typical subalpine vegetation in the Nepalese Himalayas are documented, with their confirmed plant associations. A new genus and new species, Khumbumiris schwartzi, is diagnosed and described, based on a male specimen collected from Abies spectabilis; two additional new species, Lygocoris laligurans (associated with Rhododendron shrubs) and Phytocoris sagarmathanus (Abies spectabilis), are also described. Images of the habitats and live individuals are also provided. The tribal placement of Khumbumiris is discussed in detail.
