Diagnosis. Recognised by the following combination of characters: body subovate to elongate oval ( Yasunaga & Miyamoto, 2006: figs. 1C, D; Wolski & Gorczyca, 2012: figs. 1–4), relatively large (usually over 5.5 mm); dorsum usually moderately shining, covered with dense, semierect or erect setae; head rugose ( Wolski & Gorczyca, 2012: figs. 42–43); antennal segment I constricted at basal one fourth ( Wolski & Gorczyca, 2012: figs. 3–4, 28); segment II thin, covered with moderately dense setae ( Wolski & Gorczyca, 2012: fig. 29); metepisternum covered with densely distributed punctures ( Wolski & Gorczyca, 2012: fig. 26); scutellum almost flattened or weakly arched ( Wolski & Gorczyca, 2012: 2–4; Yasunaga & Miyamoto, 2006: 1 C, D); ostiolar peritreme obtuse, matte, covered with minute, fine setae ( Wolski & Gorczyca, 2012: 27); endosoma simple; DSS thin, nearly parallel-sided along entire length or tapering; endosomal sclerites absent or very weakly developed ( Figs. 7, 10 ; Yasunaga, 2000: fig. 85; Wolski & Gorczyca, 2012: fig. 36).

Key to species of Bothriomiris

1. Pronotum with a triangular, ochraceous patch from anterior margin reaching medial portion............... B. ornatus Bergroth

– Pronotum entirely dark brown to black, rarely reddish ( Yasunaga & Miyamoto, 2006: figs. 1C, D; Wolski & Gorczyca, 2012: figs. 3–4), sometimes with an anterior lobe yellow and with a yellow swelling from anterior lobe to posterior margin ( Wolski & Gorczyca, 2012: figs. 1, 2), but never with a triangular, ochraceous patch anteriorly ....................................................2

2. Dorsal surface entirely reddish ................. B. testaceus Distant

– Dorsal surface usually dark brown or blackish brown, sometimes with yellow, reddish or ochraceous areas, never entirely reddish ( Yasunaga & Miyamoto, 2006: figs. 1C, D; Wolski & Gorczyca, 2012: figs. 1–4) .......................................................................3

3. Vertex with two distinct, broad tubercles, each situated laterally and contiguous with an inner margin of eye and occipital carina; antennal segment I longer than width of vertex ( Wolski & Gorczyca, 2012: fig. 4); left paramere with sensory lobe strongly convex, without sharply pointed process ( Gorczyca, 2005; Fig. 3 )..................................... B. sulawesicus Gorczyca

– Tubercles on vertex weakly developed; antennal segment I nearly as long or shorter than width of vertex ( Figs. 1–3 ); left paramere with sensory lobe not convex ( Wolski & Gorczyca, 2012: fig. 37), or if convex, furnished with sharply pointed process ( Gorczyca, 2005: fig. 6).............................................4

4. Dorsum varying from pale brown with reddish and yellowish areas to dark brown or blackish with yellowish stripes and/or patches ( Wolski & Gorczyca, 2012: figs. 1, 2); pronotal calli impunctate; posterior lobe of pronotum with a distinct, pale, median, longitudinal stripe ( Figs. 1, 2 ); endosoma with relatively weakly developed AES and MES ( Wolski & Gorczyca, 2012: fig. 36) ............................................... B. dissimulans (Walker)
