Sepsophis punctatus Beddome 1870, the only species of a monotypic genus, was described based on a single specimen from the Eastern Ghats of India. We rediscovered the species based on specimens from Odisha and Andhra Pradesh state, India, after a gap of 137 years, including four specimens from close to the type locality. The holotype was studied in detail, and we present additional morphologica...

The monotypical orphnine genus Stenosternus Karsch is known from a single specimen of Stenosternus costatus collected on the São Tomé island (Gulf of Guinea). The holotype of Stenosternus costatus Karsch is re-examined and its characters are discussed and illustrated. Although the genus was implicitly placed by Paulian (1984) in the Old World tribe Orphnini Erichson, re-examination of the holot...

A new genus and species of the carcharhiniform family Pseudotriakidae is described based on three specimens caught near the Socotra Islands in the northwestern Indian Ocean. The first specimen and holotype of Planonasus parini g. n. and sp. n. was caught during cruise 17 of RV 'Vityaz' in 1988/89 along the deep western Indian Ocean. Two further specimens of the new genus and species were caught...

Hildoceras bifrons (Bruguière, 1789) is a cosmopolite ammonite species from the Lower Jurassic of Boreal and Mediterranean (Tethys) palaeogeographical provinces. Inter-demic phylogenetic variability are noticeable, also affecting most distinctive morphological trait: spiral groove along whorl flank. Since XIX century, however, number morphotypes assigned to (many which Apennines other Italian l...

In 1887, Mayr described four species of the ant genus Strumigenys collected in Brazilian state Santa Catarina: unidentata, subedentata, denticulata, and crassicornis. All them were based on a series one to several specimens, without designation holotype, as usual at that time. The same can be said about eggersi, by Emery 1890 specimens Saint Thomas (U.S. Virgin Islands), holotype. 1961, Brown d...

A revised diagnosis and description of Thylacinus macknessi Muirhead, 1992 is presented following recovery of the previously unknown anterior half of the holotype. This provides the most completely represented lower dentition of a species of thylacinid other than T. cynocephalus. The new part of the holotype further confirms the thy1acinid nature of this taxon by displaying additional features ...

The enigmatic, cleptoparasitic bee genera Brachymelecta Linsley and Sinomelecta Baker (Apinae: Melectini) are redescribed, each represented by a single species which has not been reencountered since capture of the type series ca. 1878 and 1900, respectively. Both genera are the only melectines to possess two submarginal cells in the forewing but are otherwise wholly dissimilar. Brachymelecta mu...
