Tabanus rondoniensis Henriques, Krolow, Zamarchi & Camargo 2022

Tabanus rondoniensis Henriques, Krolow, Zamarchi & Camargo (Figs 50 A–D, 51) Tabanus rondoniensis Henriques et al., 2022: 3, fig. 1, A–E (description); Henriques et al., 2023: Supplemental table (Amazon biogeography); Zamarchi et al. 2023: 3, table 1 (list of species). Distribution: Brazil (Rondônia, Acre (Augusto Loureiro Henriques, Personal Communication)). Type-locality: Brazil, Rondônia, Monte Negro. Diagnosis: Relatively large specimens(15–17mm), brownish integument.Frons narrow (FI:5.5–6.0), convergent at base (DI: 1.5–1.8). Scutum and scutellum brown with mixed yellowish and black setulose, prescutellum black surrounded by white setulae that are also distributed throughout the scutellum. Wing with light brown infuscation at the anterior half. Abdomen with a single row of well-defined and connected dorsomedial light setulose triangles (tergite 2 to 5), reduced to a narrow strip on tergite 6, posterolateral margin of the tergite pale yellowish setulose (Henriques et al. 2022). Remarks: We had no specimens of T. rondoniensis available for this study and the diagnosis here was made based on the original description and illustrations (Henriques et al. 2022). The species can be easily distinguished from other species in the T. nebulosus group based on the evident and continuous dorsomedial row of triangles on the abdomen. T. guyanensis and T. comosus also have a noticeable dorsomedial row of triangles, but both species also have dorsolateral rows of triangles, which are absent in T. rondoniensis. The male is unknown.
