Abstract
The Asian neriid fly genus Telostylus Bigot (Diptera: Neriidae) is revised, including a key and illustrations of its species. Lectotype designations are proposed for four species: Telostylus babiensis de Meijere, T. decemnotatus Hendel, T. remipes (Walker) and T. trilineatus de Meijere. Two new species are described: Telostylus marshalli Sepulveda & de Carvalho, sp. n., from Sarawak, Malaysia, and T. whitmorei Sepulveda & de Carvalho, sp. n., from Masbate, Philippines. The morphology of Telostylus binotatus Bigot and T. remipes (Walker) is discussed in order to support their synonymy. Additionally, new country records are provided for four species: Telostylus babiensis de Meijere for Philippines, T. binotatus Bigot for Papua New Guinea, T. inversus Hennig for Malaysia and Indonesia, and T. trilineatus de Meijere for Malaysia and Philippines.
Highlights
The genus Telostylus was proposed by Bigot (1859) for Telostylus binotatus Bigot, 1859, a species from Indonesia characterized by having an elongate conical first flagellomere, a tomentose arista placed apically and an elongate pedicel
Almost concurrently with Bigot’s (1859) work, Walker (1860) proposed the genus Coenurgia to contain a new species from Makassar (Sulawesi, Indonesia), Coenurgia remipes Walker, 1860, using the same set of characters as used by Bigot (1859) to diagnose Telostylus
A few years later, in a short publication seeking to address some inaccuracies in previous studies, Bigot (1881) synonymized Coenurgia under Telostylus, declaring: “Mon Telostylus bimaculatus, Leptopodidae? = Coenurgia remipes (Walker), à qui appartient la priorité”
Summary
The genus Telostylus was proposed by Bigot (1859) for Telostylus binotatus Bigot, 1859, a species from Indonesia characterized by having an elongate conical first flagellomere, a tomentose arista placed apically and an elongate pedicel.
