Two new species of Phylactella (Bryozoa Cheilostomatida) from the Mediterranean area belonging to the P. labrosa (Busk) complex of species

Examination of fossil and Recent specimens from the Sicilian area belonging to the Phylactella labrosa ‘complex’ revealed two new species: P. mediterranea sp. nov., a Pleistocene-to-Recent taxon and P. megarensis sp. nov., from Pleistocene sediments from eastern Sicily. Ecological, geographical and stratigraphical distribution of both new species are discussed also in comparison with P. labrosa.     

Some new African Ulopini (Homoptera,Cicadellidae, Ulopinae)

Summary

Two new genera and two new species of Ulopini are described from Africa; the distribution, and some aspects of the evolution, of genera in this tribe are discussed. It is suggested that Ulopa damaspina Dlabola belongs to the genus Moonia Distant and a new synonmy is suggested. In an Appendix the genera and species of the Ulopini are listed according to their geographical distribution.     

Red Sea Phyllidiidae (Mollusca,Nudibranchia), with descriptions of new species

All the known Red Sea nudibranchs of the family Phyllidiidae are described and their taxonomic positions discussed. The genus Fryeria Gray, 1853, is regarded as a junior subjective synonym of Phyllidia Cuvier, 1797, and Reyfria gen. nov. is introduced to describe those species differing from Phyllidia primarily in the position of the anus. Of 12 species described here from the Red Sea, four are new to science. Phyllidia arabica Ehrenberg, 1831, is distinguished from Phyllidia varicosa Lamarck, 1801, and Phyllidia sp. is described as the third species confused with this group. A subspecies of P. ocellata Cuvier, 1804, is described and illustrated, as are three new species: P. melanocera, P. monacha and P. multifaria.     

Two new species of Rhizorhina (Copepoda: Siphonostomatoida) from leptostracan and tanaidacean hosts

Summary

Two new species of parasitic copepods from the North Atlantic, Rhizorhina leptostracae associated with Nebaliella caboti, and Rhizorhina tanaidaceae from Leviapseudes hanseni, are described. Leptostracans and tanaids are new host groups for this genus. The systematic position of Rhizorhina is discussed.     

Two new taxa from the Lesser Sundas in the genus Onthophagus (Coleoptera: Scarabaeidae: Scarabaeinae)

Two new Indonesian taxa are proposed in Onthophagus Latreille, 1802, illustrating the composite faunal spectrum of the Lesser Sundas (Indonesia): O. montishannoniae, a new species from Flores, and O. accedens nusatenggaricus, a new subspecies from Lombok and Flores. O. accedens Lansberge, 1883 is, with O. dux Sharp, 1875, placed in what is here defined as the dux subgroup within the subgenus Parascatonomus Paulian, 1932. The three included species‐group taxa are keyed, their status is discussed, and new records are given. The position of O. montishannoniae seems taxonomically and geographically isolated: this species has no known close relatives in the region, neither in the Lesser Sundas, nor anywhere else in Wallacea.     

Two new species of Metharpinia Schellenberg (Amphipoda: Phoxocephalidae) from the south-west Atlantic

Two new species, Metharpinia dentiurosoma and Metharpinia grandirama, belonging to the family Phoxocephalidae are described and illustrated from the Argentine Sea. Both taxa were collected dredging at different depths and the grain size of the sediment was determined for each sampling station. The new species share character states with Metharpinia Schellenberg, 1931 and Microphoxus Barnard, 1960, and their assignation to the first genus is discussed. Metharpinia dentiurosoma and Metharpinia grandirama are distinguished from the other known species of the genus by the dorsal hook on urosomite 3; in addition, the first species is characterized by its epimeron 3 and the second species by its uropod 2.     

A revision of the genus Ophiambix (Echinodermata: Ophiuroidea) including the description of a new species

The genus Ophiambix is revised and problems at higher taxonomic levels are discussed. The species Ophiambix aculeatus, O. meteoris and O. devaneyi are redescribed (based on new characters), and a new species O. epicopus is described from the Kermadec Islands, South Pacific. A pictorial key is presented to aid identification.     

Two new phoxocephalids (Crustacea: Amphipoda: Phoxocephalidae) from the south-west Atlantic

A new genus and species, Parafoxiphalus longicarpus, and a new species, Metharpinia protuberantis belonging to the family Phoxocephalidae, are described from the Argentine Sea. Both taxa were collected from sandy substrata in the intertidal and subtidal regions. Parafoxiphalus longicarpus is related to Foxiphalus Barnard, 1979 and they share many characters, most of them in plesiomorphic condition. Metharpinia protuberantis is an intermediate species between Metharpinia Schellenberg, 1931 and Microphoxus Barnard, 1960, and its assignation to the first genus is discussed.     

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.     

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.

Pseudonemesia tabiskey,a new species of Pseudonemesia Caporiacco 1955 and new ultramorphological data for the Microstigmatinae (Araneae: Microstigmatidae)

Pseudonemesia tabiskey sp. nov. is described from an Andean Forest in Trujillo, Venezuela. The new species is the third for the genus and differs from the other two species by the presence of one short and apically rounded modified seta on the retrolateral distal portion of the male tibia I and clavate setae on the dorsal and lateral sides of abdomen in both sexes. A new diagnosis is given to Pseudonemesia and new morphological data based on scanning electron microscopy for the Microstigmatinae are presented. The presence of posterior median spinnerets in Pseudonemesia is discussed.     

Two new genera of Bryozoa (Calloporidae) from New Zealand

Two new genera of the bryozoan family Calloporidae are described from New Zealand. The first, Leptinatella, is introduced for L. gordoni n. sp., specimens of which have been referred in the past to Watersia militaris (Waters) but are distinct from this species, which is a phase of the cribrimorph Corbulipora tubulifera (Hincks). The second genus, Bryocalyx, is introduced for B. cinnameus n. sp., which has small, conical colonies anchored by rhizoids. Another species of Bryocalyx is known from a few fragments only: and has also been referred in the past to Watersia sp. It is briefly discussed, but left unnamed here.

A key is given for the separation of the four Afrotropical species of Aenasius and the male of A. comperei is described for the first time. Incisencyrtus gen. n. is described for the following three new Afrotropical species: secus (the type-species), sirus and afer. Cladiscodes incisius sp. n. is described from South Africa and it represents the first species of this genus from Africa. New distribution records are given for three Alfrotropical species of Metaphaenodiscus.
