Tabanus vaseyi Sherman, a new species of tabanid from Vietnam and a redescription of Tabanus flavioculatus Toumanoff (Diptera: Tabanidae)

Abstract

A new species of Tabanidae, Tabanus vaseyi Sherman, n. sp., is described from Vietnam and differentiated from Tabanus cepuricus Surcouf. Tabanus flavioculatus Toumanoff is redescribed; anatomical features and variation not noted in the original description are given, along with a discussion of the taxon. It is recorded for only the second time and is newly recorded from Vietnam. Conflicting reports on the type data and type depository for the paratype of Tabanus sphinx Philip (= T. cepuricus) are clarified. Collection data of the only specimen of Tabanus soubiroui Surcouf known from Vietnam are recorded. Taxa from Southeast Asia related to T. vaseyi and T. flavioculatus are discussed briefly.
