Osteochilus spilurus is one of the native fish in Indonesia. This species from North Lampung has variations body shape with populations Bangka and Belitung. Morphological plasticity genetic variation are potential causes these differences. To confirm this, it necessary to identify molecular using mitochondrial cytochrome b (cyt b) gene. Fish samples had morphological characters that matched des...
Parachiloglanis bhutanensis is a newly discovered species of torrent catfish from eastern Bhutan. With its discovery, the genus Parachiloglanis is no longer monotypic. The species differs from Parachiloglanis hodgarti in meristic, mensural, and coloration characters. Parachiloglanis bhutanensis is confirmed as a member of the genus by the absence of a post-labial grove on the lower lip, which i...
The systematic status and the evolutionary biology of chub mackerel (Scomber japonicus) in the South West Atlantic Ocean is confusing with an unknown degree of genetic differentiation and reproductive isolation between units. Simultaneous genetic and morphologic analyses were made on 227 fish collected from two areas of the South West Atlantic Ocean and one from the Mediterranean Sea. The genet...
A new species of slender skink is described from the Philippines. The species is endemic to Lubang Island, and is assigned to the Brachymeles bonitae Complex based on phenotypic and genetic data. Specimens were collected from Lubang Island between 1991 and 2012, and were examined based on morphological data (qualitative traits, meristic counts, and mensural measurements). Published genetic sequ...
The genus Caecidotea is represented by 2 species in Massachusetts, C. communis and C. r. racovitzai. Caecidotea r. racovitzai is restricted to western portions of the state while C. communis occurs throughout the state. Collections of Caecidotea sp. are demonstratively unispecific in drainages where both species are found. Subsequent collecting in 2 localities that formerly produced both specie...
Phalotris labiomaculatus Lema, 2002 was described based on a single specimen from Porto Franco, south of the Brazilian state of Maranhão, being rediscovered three years later in Mateiros, a municipality in the north of the state of Tocantins, attesting to its occurrence in the cerrado of both banks of the Tocantins River. The discovery of 28 new specimens from other localities during field expe...
