Tabanidae (Diptera) of Maranhão state, Brazil. V. Description of Protosilvius gurupi sp. n. (Pangoniinae, Pangoniini) and key to Protosilvius species

“…20 ). According to Chainey and Hall (1996) , female specimens of Protosilvius differ from Boliviamyia Chainey & Hall by a frons without callus, a slender palpus without a dorsal groove and apparently absent mandibles and both sexes have the antennal flagellum with a very short and/or irregular postpedicel and very long and slender apical flagellomeres.…”

Tabanids in South America

“…The species have dark eyes, subulate antennae, frons with a circular-shaped callus, palpi with a short apical segment, sternite 8 of female very wide basally [19]. Chainey and Hall provided a picture of the front view of male head of Fairchildimyia penai Philip and Coscarón, comparing it with Boliviamyia fairchildi Chainey and Hall, the species described in that paper [73].…”

“…They have naked eyes, prominent appendix in fork R4 vein, face not produced conically and proboscis rarely exceeding the length of the head, as frequent in Scionini [19]. With the exception of the species of Esenbeckia, specimens of this tribe are rarely collected and do not seem to be very active bloodsuckers [73]. The tribe has 14 genera in which the majority is in South America.…”

“…The other genera of Pangoniini are all monotypic: Archeomyotes Philip and Coscarón, 1971, Austromyans Philip and Coscarón, 1971 Chaetopalpus Philippi, 1865, each with an endemic species of Chile [20]. The recent genus Boliviamyia Chainey and Hall has only one endemic species from Bolivia, Boliviamyia fairchildi Chainey and Hall [73]. (Bequaert, 1930) It has only the genus Scepsis Walker, 1850 with a single Neotropical species, Scepsis appendiculata Macquart, which appears in catalogs as Scepsis nivalis Walker [20,31,34,82].…”
