The Raffles Bulletin of Zoology is a journal of Southeast Asian Zoology published by the Lee Kong Chian Natural History Museum. The journal bore three different names in its history, mirroring the changing (and almost disastrous) fate of the zoological collection. The history of the zoological collection can be read here.

Revision of Ngirhaphium (Insecta: Diptera: Dolichopodidae), with the description of two new species from Singapore's mangroves.

Patrick Grootaert and Jayanthi Puniamoorthy

The type-species of Ngirhaphium Evenhuis & Grootaert, N. murphyi is re-described. Two new species are described from mangroves in Singapore: N. sivasothii, new species, and N. caeruleum, new species. A key to the three known species of the genus is given and male genitalia are illustrated. read more

Molecular phylogeny and classification of Lyropaeini (Coleoptera: Lycidae) with description of larvae and new species of Lyropaeus

Michal Masek, Michael A. Ivie, Vaclav Palata and Ladislav Bocak

The generic classifi cation of Lyropaeini is revised on the basis of molecular phylogeny. Two lineages mark the basal split of Lyropaeus Waterhouse, 1878: the Indian-Sri Lankan-Vietnamese clade (subgenus Lyropaeus s. str.) and the East Oriental clade (subgenus Lyroneces Kazantsev, 1998). Lyroneces is demoted to a subgenus of
Lyropaeus due to the absence of reliable morphological characters. read more

Tridacna noae (Röding, 1798) – a valid giant clam species separated from T. maxima (Röding, 1798) by morphological and genetic data.

Y. Su, J.-H. Hung, H. Kubo and L.-L. Liu

The taxonomic status of a giant clam species Tridacna noae (Röding, 1798) in relation to its congener T.maxima (Röding, 1798) was examined by a combination of molecular and morphological analyses. Until recently, T. noae was considered conspecifi c with T.maxima. However, in this study, among the four genes (COI, 16S rRNA, 18S rRNA, 28S rRNA) examined, two (i.e., 16S rRNA and COI) genes grouped T. maxima into two distinct clades, suggesting that a cryptic species was involved. read more

On the land snail Rhagada Albers, 1860 (Gastropoda: Camaenidae) from across the Lesser Sunda Islands

Frank Köhler

Six land snail species from across the Lesser Sunda Islands have so far been assigned to the camaenid genus Rhagada Albers, 1860. Previous taxonomic treatments have emphasised shell features, which were usually inferred from small series of specimens. Based on the study of newly collected, ethanol preserved material from various islands, I compared the penial anatomy of four species and analysed the mitochondrial differentiation of three. In addition, I completely review the previous literature on the Lesser Sunda species.. read more
