The skink Chalcides ocellatus (Forskal) is distributed around the Mediterranean region, Arabian Peninsula, and Horn of Africa. We examined C. ocellatus from Yemen and Somalia to clarify the biogeography of the species in the region of the Red Sea/Gulf of Aden. We examined 3612 bp of partial and complete mtDNA fragments (12S, 16S, ND1, cyt b, ND4, and adjacent tRNA) and 5380 bp of partial nuclear DNA fragments (BDNF, C-MOS, Rag1, PNN, and R35). Bayesian inference and Maximum-likelihood analysis placed the Somalia and Yemen specimens with those from the Eastern Mediterranean. We were unable to resolve a split between East African (Somalia) and Arabian (Yemen) populations with mtDNA, nuclear loci, and combined loci analyses.
We describe a new species of Oedipina (subgenus Oedopinola) from Parque Nacional Pico Bonito in the central portion of the Cordillera Nombre de Dios in north-central Honduras. The new species was previously assigned to O. gephyra, but a combination of molecular analyses and its differences in foot morphology diagnose it from O. gephyra.
Five European species of the genus Tetragoneura Winnertz (Diptera: Mycetophilidae) are reviewed. Male terminalia of all species as well as female terminalia of T. ambigua Grzegorzek, T. sylvatica Curtis and T. ruuhijarvi sp. n. are illustrated on the base of type and newly collected material. Two species: T. ruuhijarvi sp. n. and T. pudogensis sp. n. are described based on specimens collected in Finland and Russian Karelia. T. sibirica Maximova is found to be a junior synonym of T. obirata Plassmann. Key to European species is provided.
Tagalis baenai sp. nov., T. grossii sp. nov. and T. marquesi sp. nov. from Brazil are described. Morphological variations and male genitalia of Tagalis inornata inornata Stål, 1860, are described. A revised key to the species of Tagalis Stål, 1860, is presented.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
