Eviota santanai is described based on four specimens from Timor-Leste, taken in 5-8 m depth. In general coloration pattern, the species is most similar to E. latifasciata, but differs in the cephalic sensory-pore system pattern, the absence of an occipital spot, and live color including pinkish-mauve bars. Eviota santanai has a dorsal/anal fin-ray formula of 8/8, 5th pelvic-fin ray absent, some...

Three species of the ophidiid genus Neobythites containing ocelli in the dorsal fin are known from the West Atlantic: Neobythites gilli Goode and Bean 1885, N. ocellatus Günther 1887 and N. monocellatus Nielsen 1999. In the year 2000, 18 specimens of Neobythites were caught on the upper continental slope off eastern Brazil. This is the first documented record of a Neobythites specimen off Brazi...

The banded basslet, Lipogramma evides Robins & Colin, 1979, is shown to comprise two species: Lipogramma evides, which inhabits depths of 133-302 m, and a new species described here as Lipogramma levinsoni, which inhabits depths of 108-154 m and previously was considered to represent the juvenile of Lipogramma evides. A second new species of banded basslet, described here as Lipogramma haberi, ...

Five specimens of the non-native three spot gourami (Osphronemidae: Trichogaster trichopterus) were collected from a small pond near the northern coast of Jamaica in June 2009. The collection represents the first documentation of this species in Jamaica. Origin of the introduction is not known. Herein, we discuss the occurrence of this species in Jamaica and possible threats posed to the island...

Tilapia cabrae Boulenger, 1899, a cichlid fish from coastal lowlands of the Republic of Congo (Africa), was examined for gill parasites. Four new species of the Monogenea were found, all belonging to Cichlidogyrus (Ancyrocephalidae): C. berradae sp. n., C. revesati sp. n., C. legendrei sp. n., and C. lemoallei sp. n. A possible relationship between the relative size of haptoral sclerites (i.e.,...

Three new species of Glossogobius are described from New Guinea. Glossogobius multipapillus, n. sp. from northeastern New Guinea has a lobed mental fraenum and a distinctive papilla pattern unlike any other species in the genus. Glossogobius sentaniensis, n. sp. is described from Lake Sentani. The species is similar to Glossogobius aureus and G. koragensis differing in head pores and large dark...

Juvenile growth rate is an important life-history trait that affects the size at maturity, and may influence the development of sexual ornamentation. The sword of several species of the genus Xiphophorus (Teleostei: Poeciliidae) is an elaborate secondary sexual trait that confers an advantage in terms of sexual selection, counterbalanced by locomotive and predatory costs. This study assesses di...

Adipose fins are found on approximately 20% of ray-finned fish species. The apparently rudimentary anatomy of adipose fins inspired a longstanding hypothesis that these fins are vestigial and lack function. However, adipose fins have evolved repeatedly within Teleostei, suggesting adaptive function. Recently, adipose fins were proposed to function as mechanosensors, detecting fluid flow anterio...

Data is presented in support of model-based total evidence (MBTE) phylogenetic reconstructions of the Neotropical clade of Gymnotiformes "Model-based total evidence phylogeny of Neotropical electric knifefishes (Teleostei, Gymnotiformes)" (Tagliacollo et al., 2016) [1]). The MBTE phylogenies were inferred using a comprehensive dataset comprised of six genes (5277 bp) and 223 morphological chara...

The black bullhead is an invasive species that forms dense populations and has a negative impact on the native ichthyofauna. Recent studies indicate it one of most dominant fish in Serbian waters. Feeding habits based stomach contents individuals caught Lake Sava were analyzed as first step towards evaluating its possible fauna lake. following indices for diet analysis applied: vacuity index, f...
