XXIII.—The genera of Stephanoceras and allies

Summary

An illustrated key is given to the 6 species of Enicospilus found on the Galápagos Islands. Five, E. stylus, E. katanus, E. vidus, E. donor and E. ditor, are described as new and one Neotropical species, E. trilineatus (Brullé), is recorded for the first time from these islands. The relationships between the Galápagos and continental South American species are briefly discussed.     

First described fossil representatives of the parasitoid wasp taxa Asaphesinae n. n. and Eunotinae (Hymenoptera: Chalcidoidea: Pteromalidae sensu lato) from Eocene Baltic amber

ABSTRACT

New Baltic amber species of Pteromalidae sensu lato are described, from two different subfamilies, Asaphesinae n. n. and Eunotinae. Asaphesinae is provided as a replacement name for Asaphinae Ashmead 1904, which is a junior homonym of the trilobite family Asaphidae Burmeister 1843. Coriotela lasallei gen. n., sp. n.. and Butiokeras costae gen. n., sp. n.. are described as the first known fossil species of Asaphesinae and Eunotinae, respectively. These species establish the minimum known age of both groups in the Eocene. Taxonomic changes are also proposed for some extant species. The genus Desantisiana Neder de Román syn. n.. is found to be a junior synonym of Notoglyptus, and its only described species is transferred as Notoglyptus jujuyensis (Neder de Román) comb. n.. The tribe Calyconotiscini, previously classified in Eunotinae, is abolished and Calyconotiscus Narendran & Saleem is transferred to Pireninae.

A new genus of dung beetles (Coleoptera: Scarabaeidae: Scarabaeinae) endemic to the Brazilian Atlantic Forest

ABSTRACT

A new genus of the tribe Deltochilini, Atlantemolanum new genus, endemic to the Atlantic Forest of Brazil, is proposed here to include two species formerly described in the genus Deltochilum based on the unique morphologic characters shared by Deltochilum riehli = Atlantemolanum riehli (Harold 1868) new combination and Deltochilum costalimai = Atlantemolanum costalimai (Pereira and D’Andretta 1955) new combination.

A report on the cheilostome Bryozoa of the Sudanese Red Sea

Summary

Eighty-six species of bryozoa are listed from collections from reefs in the Sudanese Red Sea, increasing the known fauna list by 30 species. The abundance, in terms of numbers of colonies, and the distribution of nineteen species has been analysed over a range of 30 metres depth. The character of the genera Calyptotheca Harmer and Emballotheca Levinsen are briefly discussed. C. thornelyae is introduced for Lepralia subimmersa Thornely not MacGillivray, and E. harmeri for E. acutirostris Harmer not Canu and Bassler. In addition, three new species of Calyptotheca, C. heteroavicularia, C. nigra and C. sudanensis, and one of Escharoides, E. longirostris, are described.     

Two new Andean species of Anolis lizard (Iguanidae: Dactyloinae) from southern Ecuador

ABSTRACT

We describe two new species of Anolis lizard that are sympatric on the Amazonian slopes of the Andes of southern Ecuador at elevations between 1440 and 1970 m. The new species may be distinguished from other Anolis by external anatomy, mitochondrial divergence and dewlap colour. We estimate the phylogenetic positions of the new species using Bayesian analysis of DNA sequence data including all species of Dactyloa-clade Anolis for which DNA data are available. Anolis hyacintogularis sp. nov. is sister to Anolis calimae, whereas Anolis lososi sp. nov. is sister to Anolis williamsmittermeierorum, herein reported for Ecuador for the first time. Individuals of both new species were collected within a protected area in southern Ecuador, Podocarpus National Park, which suggests that at least some populations of these species are well protected.

Noyesaphytis (Chalcidoidea: Aphelinidae) – an unusual new genus from Madagascar,and a reassessment of Aphelininae classification based on morphology

ABSTRACT

Noyesaphytis Polaszek & Woolley gen. nov. (type species Noyesaphytis lasallei Polaszek & Woolley sp. n. ) is described from Berenty, Tuléar, Madagascar. The genus differs from its closest relatives primarily in the structure of the female antenna, which has a single, elongate flagellum preceded by four anelli, the largest of which could be interpreted as a single anelliform funicle. This type of antenna is unknown in other Aphytini, but approaches the condition found in many Signiphoridae. Noyesaphytis possesses a character state that was until now thought to be an autapomorphy of Azotidae (sole genus Ablerus), being the groove in front of the propodeal spiracle. A second putative autapomorphy shared by Azotidae and Signiphoridae, and also Noyesaphytis, is the presence of anterior projections on the metasomal sterna. However, in Azotidae and Signiphoridae these are narrow, whereas as they are broader in Noyesaphytis. The form of the wing is consistent with Aphytini, although lacking a linea calva. The presumed male of Noyesaphytis lasallei has an antennal structure completely unknown in Aphelinidae, with a 1-segmented clava preceded by an extremely elongate single funicle, and four anelli. Differences between the female and male are discussed, some of which could indicate that the male might eventually be shown to belong to a different species, although the species are undoubtedly congeneric, despite the striking difference in antennal structure which is common in Aphelinidae. The male genitalia also suggest Aphytini. Based on a phylogenetic analysis of 50 morphological characters, we provisionally place Noyesaphytis in Aphytini pending the results of a forthcoming phylogenomic analysis. The new genus is named for its collector, John Noyes (NHM, London), and the new species is named after the late John La Salle.

Miscellanea Nematodologica. VI. Echinonema australis sp. nov. from Sminthopsis crassicaudata in South Australia

Summary

Echinonema australis sp. nov. is described from Sminthopsis crassicaudata, and differs most markedly from the only other species of the genus, E. cinctum, in lacking a swollen region with intermediate sized spines immediately posterior to the three circles of large spines which occur on the extreme anterior end of the body.     

A comparative study of the larval development of Monodaeus couchi (Couch), Xantho incisus Leach and Pilumnus hirtellus (Linnaeus) (Crustacea: Brachyura: Xanthidae)

Summary

Comparative accounts are given of the larval and first crab stages of three crab species belonging to the family Xanthidae: Monodaeus couchi (Couch), Xantho incisus Leach and Pilumnus hirtellus (Linnaeus). Features are discussed that distinguish the larvae of these species from those of other N.E. Atlantic brachyrhynch crabs.

Phylogenetic taxonomy of Hemiphyllodactylus Bleeker, 1860 (Squamata: Gekkonidae) with descriptions of three new species from Myanmar

ABSTRACT

A phylogenetic taxonomy of the gekkonid genus Hemiphyllodactylus based on molecular, morphological, and ecological data recovered 28 species, including three new species from the upland regions of the Shan Plateau in eastern Myanmar. Hemiphyllodactylus linnwayensis sp. nov. is a forest-adapted species that may also be a human commensal and H. montawaensis sp. nov. and H. tonywhitteni sp. nov. are karst forest-adapted species. The discovery of three new species from montane regions in eastern Myanmar extends the distribution of a larger monophyletic group of Hemiphyllodactylus westward to the eastern edge of the Ayeyrawady Basin through a series of semi-contiguous, parallel mountain ranges originating in western China and northern Thailand. The discovery of the karst forest-adapted H. montawaensis sp. nov. and H. tonywhitteni sp. nov. further emphasizes the unrealized herpetological diversity endemic to karst ecosystems and the need for increased field work throughout such habitats in South-East Asia.

Lanayrella,a new Acteonidae genus (Gastropoda,Heterobranchia) from Tierra del Fuego

ABSTRACT

We introduce herein Lanayrella gen. nov. to accommodate two Acteonidae species that have proven resistant to stable classification: Tornatella vagabunda Mabille, 1885 and Acteon ringei Strebel, 1905. The new genus is diagnosed by a protoconch fully immersed within the shell and a platform-like columellar region of the aperture, which bears a strong and sharp adapical fold. Both species are restricted to Tierra del Fuego: Lanayrella vagabunda comb. nov. on the Chilean part and Lanayrella ringei comb. nov. on the Argentinean side.

XIII.—The recent voles of the Microtus nivalis group

Summary

The study of the flora of the alimentary canal of D. frischii reveals the presence of bacteria E. coli, Staphylococcus, Proteus and unspeciated members of the family Enterobacteriaceae. The presence of the members of Enterobacteriaceae in the flora indicates the possibilities of gastro-intestinal disorders in the human population and its public health importance has been stressed.

Praeschuleridea ventriosa ventriosa (Plumhoff) and Paraschuleridea ornata Bate [Ostracoda] from the Bajocian of N.E. England

Summary

The ostracod Praeschuleridea ventriosa ventriosa (Plumhoff) (Bate 1963 b: 39) described from the Bajocian Basement Beds of Yorkshire, N.E. England is critically reviewed. The placing of Paraschuleridea ornata Bate (1963: 37) into synonymy with this species by Malz (1966: 399) is rejected. The British material first described as Praeschuleridea ventriosa ventriosa (Plumhoff) is recognised as a new species and described as Praeschuleridea decorata sp. nov.     

The world Rhyparochrominae (Hemiptera:Lygaeidae)

Summary

The species of Epitraninae, a subfamily of Chalcididae, parasitic Hymenoptera, are taxonomically revised, from an area including India in the west and New Guinea in the east. Over 500 specimens were studied, including all accessible types. Only one genus, Epitranus Walker, is recognized and its synonymy corrected. A key is given to 29 species of which 17 are described as new and among the earlier names 30 were found to be junior synonyms (and some more are probable synonyms, as suggested in the paper, among the names the types of which were not examined). The treated and illustrated valid species include two from Australia and notes and a figure of another species, E. evanioides, from Mauritius. Two Oriental species were found widely distributed also in Africa: E. observator and E. clavatus. The latter was also recorded in the New World, probably having been inadvertedly introduced. One Oriental species, E. erythrogaster, is not only widely distributed but has an unusual range of variation and may prove to be a composite aggregate when more information is available. Little help could be drawn from the biological data because definite host records are available only for four species.     

Foraging patterns and artificial fragrance choices of male orchid bees in the Brazilian Atlantic Rainforest

ABSTRACT

With the aim of increasing our knowledge concerning fragrance choices by male euglossine bees (Apidae, Euglossini), we investigated: (i) possible foraging patterns and choices of artificial fragrances explored by the most frequent species attracted to scent baits during the same season across consecutive years, sampled invariably in a same study area; (ii) the foraging patterns of populations of orchid bees surveyed in two similar forest habitats (Atlantic rainforest remnants) located 24 km apart, on Superagui Island (SI) and on a private reserve (RNSM), in southern Brazil. Although in both areas males attracted to scent baits were collected with insect nets and odour traps during the warm-wet season, the number of samplings were different in both study sites, totalling 15 samplings on RNSM and five on RNSM. In both areas four euglossine species were the most abundant: Euglossa annectans, E. stellfeldi, E. iopoecila and E. roderici. Overall, we can draw three main conclusions. Firstly, there were conspicuous patterns in regard to the set of fragrances visited by the four most abundant euglossine species over the three consecutive years of surveys on SI, with some shifts in fragrance choices found only for E. annectans and E. stellfeldi. Second, the most attractive fragrances used distinctively by each species were very similar in both study areas, indicating a local intraspecific similarity in the use of some main fragrances. Third, E. annectans showed a clear tendency to occupy a broader niche, which probably resulted in the highest percentages of niche overlap.     

The structure and function of the adhesive organs on the antennae of male Harpocera thoracica (Fallen) (Miridae; Hemiptera)

Summary

S.E.M. micrographs of unusual setae on the male antennae, and of the female pronotum in Harpocera thoracica (Fallen) (Miridae; Hemiptera) are presented. The adhesive function and positioning of the male antennae on the female's pronotum during pairing is discussed.
