The genus Teloneria Aczél, 1954 is resurrected from synonymy with Chaetonerius Hendel, 1913 to include four species: Teloneria apicata (Edwards, 1919) comb. nov., Teloneria bimaculata (Edwards, 1919) comb. nov., Teloneria juceliae Sepúlveda & Souza sp. nov. and Teloneria ladyae Sepúlveda & Souza sp. nov. Lectotypes for Telostylus apicatus Edwards, 1919 and its junior synonym, Telostylinus apicalis Enderlein, 1922, and for Telostylinus ornatipennis Enderlein, 1922, junior synonym of Teloneria bimaculata comb. nov., are designated. An identification key to Chaetonerius, Telostylus Bigot, 1859 and Teloneria, with emphasis on the identification of the species of Teloneria, illustrations and distribution data are provided.
Chaetonerius Hendel is the only native genus of Neriidae from the African continent, with 21 species described. Although widely distributed across the Afrotropical region, the species of Chaetonerius are still poorly known and recent efforts are being devoted to clarify the taxonomy of the family and discover its diversity. Here, we describe a new neriid species from Tanzania, Chaetonerius stichodactylus sp. n. Illustrations of the male holotype, including the external and internal genitalia, are presented and a key for the species of Neriidae of Tanzania is provided.
Quichuana Knab, 1913 is a Neotropical genus of flower flies (Diptera: Syrphidae) with 50 valid species. Adults of this genus are flower visitors and their larvae are usually associated with the phytotelmata of bromeliads and heliconias, actively participating in the recycling of nutrients in forest environments. Despite their importance in ecosystem dynamics, Quichuana larvae are poorly known. Herein we describe the immature stages of Quichuana pogonosa Fluke, 1937 from samples collected from the phytotelmata of two terrestrial bromeliad species in the state of Paraná, Brazil. We provide illustrations of the egg, third instar larva and puparium, as well as information on the life cycle of the species. Additionally, we describe and illustrate the male genitalia and present the DNA-barcoding based on larva and adult specimens.
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.
