VIII.—Notes on the Silurian Brachiopod genera Delthyris,Uncinulina, and Meristina

Summary

In this paper the different interpretations of the genus Delthyris are discussed, and that given by Schuchert in 1913 is adopted with slight amendment. The species Delthyris elevata, D. crispa, D. elegans (nom. nov. for D. crispa, Hisinger, non Linnæus), and D. tenuilamellata, sp. n., from the British Silurian, are all described and figured.

The distinguishing characters of the genera Uncinulus and Uncinulina are pointed out, and Uncinulina is retained with U. fallaciosa as genotype. Rhynchonella stricklandi and Terebratula lewisi are transferred to the genus Uncinulina. Meristina tumida (Dalman) is shown to be a synonym of Meristina obtusa (Sowerby).

The British Silurian Spirifers can be separated into two groups:—(1) those with longitudinal folds and a transverse ornament of imbricating lamellæ (=Delthyris of Dalman) and (2) those with longitudinal folds bearing fine continuous longitudinal striæ (=Eospirifer of Schuchert).

The species referable to both these genera have as a rule been assigned to the genus Spirifer, from which, however, they differ in internal characters.     

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.     

On the new goby,Ctenogobius veliensis (Teleostei: Gobiidae) from the South-West coast of India

Summary

Ctenogobius veliensis, a new species of gobiid fish is described from the South-West coast of India. The characters of the fish conform to those of the genus Ctenogobius Gill but differ markedly from those of other recorded species of the genus. Apart from the usual, external morphological, morphometric and metistic characters, several other features such as the cephalic-lateralis system, skeletal features and morphology of the alimentary canal are also studied and have been found to be of significance for identifying the species. The fish shows distinct sexual dimorphism in many features.     

Lasalleistichus a new genus of Tetrastichinae (Hymenoptera: Eulophidae) from the Neotropical region,including four new species

ABSTRACT

A new genus, Lasalleistichus, is described based on material from the Neotropical region (Brazil, Costa Rica, Peru). This new genus includes four species: L. albiclava, L. albifasciatus, L. fuscicoxa, L. longicaulis, all spp. n. and described here. The group is mainly female based, males are known only for L. albiclava. There is no biological information available for this group.

Larvae of Homola (Crustacea; Dromiacea) from South Africa

Summary

Five zoeal stages of probably a single Homola species from the S.E. Atlantic are described. There are six zoeal stages in this species, of which the first is lacking from the present series. The zoeae probably belong to Homola barbata Fabr., linking the stages previously described by Pike and Williamson (1960) and by Rice (1964), giving a good idea of the complete larval development of this genus. Anomalies in the published work, however, point to the existence of taxonomic problems not previously apparent from studies on the adults alone.

The absence of exopods from the legs of these larvae adds further support to the contention that the grouping of the Dromiidae and Homolidae together in the Dromiacea is artificial.     

Pherbina mediterranea: immature stages,biology, phenology and distribution (Diptera: Sciomyzidae)

The egg, three larval instars, and puparium of Pherbina mediterranea are described. The duration of the various immature stages indicates that this specis is univoltine and spends the winter as quiescent larvae. The biology, phenology and geographical distribution are presented. The main features of the larvae are illustrated with scanning electron micrographs. A key to the adults of genus Pherbina is given.     

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.     

Natural history and ecological niche modelling of coastal Atyphella Olliff Larvae (Lampyridae: Luciolinae) in Vanuatu

ABSTRACT

The genus Atyphella Olliff includes several coastal species with larvae that were collected on coastal rock within the intertidal zone. Recent fieldwork in Vanuatu has expanded the distribution of these insects and begun to provide insight into how they are able to survive in such a unique environment. An ecological niche model is produced using Maxent to predict additional locations of coastal Atyphella in the South Pacific. Larval instars for the two species of Atyphella in Vanuatu are estimated using protergum shield width measurements. Additionally, submersion tests were performed on larvae to determine survivability in saltwater and freshwater environments. These data provide evidence for previously unknown aspects of their natural history that strongly suggest the species are multivoltine and spend a large portion of their larval stage in the intertidal zone.     

Re-evaluation of the fossil Phoridae (Diptera)

I re-evaluated the known fossil phorids after re-examining much of the Baltic amber and Dominican amber fauna. Many extant genera reported from Eocene Chinese and Eocene/Oligocene Baltic amber are actually not present; instead there are representatives of relatively primitive stem-group taxa. A new genus and species of fossil phorid, Limulomyia tyche, based on a male and a limuloid female, is described from Baltic amber. Some changes in the taxonomy of amber phorids are proposed: Pseudometopina Disney is synonymized with Metopina Schmitz (new synonymy), Diplonevra meunieri Brues is transferred to the genus Godavaria Brown (new combination), Protophorites fimbriatus Brues is considered a junior subjective synonym of Protoplatyphora tertiaria Brues (new synonymy) and Phalacrotophora tertiara Statz is transferred to the genus Gymnophora (new combination). The oldest confirmed dates for extant phorid genera are given.     

VI.—Revision of the species of Hyrax,founded on the specimens in the British Museum

Summary

Spirocamallanus olseni, previously known only from Madagascar in lutjanids and a remora, also infects the lutjanid, Lutjanus fulviflamma, in the Gulf of Elat; it becomes the second member of the genus reported from the Red Sea. Procamallanus elatensis sp. nov. from two siganid fishes becomes the second known Red Sea species in that genus, but appears most related to two other species from signaids. It can be characterized by having a distinct ledge in the buccal capsule anterior to the basal ring and an excretory pore anterior to the nerve ring. In the male, a gubernaculum and three pre-cloacal plus five post-cloacal papillae are present and the spicules have blunt tips with a crook and a ratio of 1:2·4 to 3·3. In the female, the vulva occurs 33 to 45% of the body length from the anterior end.     

A survey of the genus Stegana Meigen from southern Japan (Diptera,Drosophilidae), with descriptions of three new species

Nine species of genus Stegana from southern Japan, including three new species, S. (Oxyphortica) nigripennis Hendel, S. (Steganina) ctenaria Nishiharu, S. (Steganina) izu Sidorenko, S. (Steganina) kanmiyai Okada and Sidorenko, S. (Steganina) masanoritodai Okada and Sidorenko, S. (Steganina) ornatipes Wheeler and Takada, S. (Oxyphortica) dendrobium sp. nov., S. (Steganina) biprotrusa sp. nov. and S. (Steganina) bacilla sp. nov. are surveyed and described with designation of a new synonym S. (Steganina) maymyo Sidorenko. A key to all species of genus Stegana from southern Japan is provided.     

Redescription of the genus Noteochordodes,reinterpretation of Noteochordodes dugesi (Camerano, 1898), a new combination of Neochordodes talensis (Camerano, 1897) and a description of a new species

Three species of the freshwater genus Noteochordodes (Nematomorpha) have been reported from Argentina. In this reinvestigation Neochordodes talensis is included into Noteochordodes on the basis of its cuticular structure. The ultrastructural study of the holotype of N. dugesi showed features which are correspondent with the genus Pseudochordodes. Consequently, some specimens formerly assigned to this species have been assigned to a new species, Noteochordoeds cymatium. Another new species, Noteochordodes achosmosus is also described. Therefore, we regard five species to be valid for the genus Noteochordodes: N. achosmosus, N. cymatium, N. desantisi, N. talensis and N. saltae.     

Generic status and redescription of the Mediterranean fish Gobius liechtensteini Kolombatovic, 1891 (Teleostei: Gobioidea), and its affinities with certain American and Indo-Pacific gobies

Summary

A new monotypic genus, Corcyrogobius, is proposed for the gobiid fish, Gobius liechtensteini Kolombatovic 1891, known only from its Adriatic typelocality of Kor?ula, Yugoslavia. The species is redescribed and a lectotype designated from probable syntype material, which also includes examples of Odondebuenia balearica (Pellegrin & Fage, 1907), supposed by Kolombatovic to be adults of G. liechtensteini. The affinities of C. liechtensteini and the related genus Odondebuenia are discussed with reference to American seven-spined gobies, the Indo-Pacific Gladiogobius, and the subfamily Lioterinae, currently placed in the Eleotridae. Overall similarities between these gobies are described, their possible phylogeny outlined, and the Lioterinae transferred to the family Gobiidae.     

The family Platypodidae (Coleoptera) of Nigeria,West Africa—A faunal list

Summary

Three species of Trichomycetes were found in New Zealand Austrosimulium (Austrosimulium) Tonnoir larvae; Harpella melusinae Léger &; Duboscq, Smittium sp. and an unidentified genistellacean. All three are new Southern Hemisphere records. The commonest species, H. melusinae, was found in seven species of Austrosimulium being particularly abundant in A. (A.) tillyardianum Dumbleton. In a sample of A. (A.) tillyardianum examined from the Wainui Valley Stream, Canterbury, it was found that H. melusinae was able to infect and produce trichospores in second instar larvae, and that the number of thalli and trichospores per larva increased in each subsequent instar.
