Tachytatus Bergroth, 1918

Tachytatus Bergroth, 1918: 75 . Type species: Tachytatus prolixicornis Bergroth, 1918 , by original designation. Tachytatus: SCUDDER (1957) : 153 (in Stygnocorini ); SLATER (1964): 1056 (bibliography, in Ozophorini ).

Redescription. Body elongate, integument with slightly shining greyish pruinosity. A broad transverse fascia along basal margin of pronotum medially extending to transverse furrow; central part of scutellum, clavus at apex of scutellum, a broad fascia on corium at apex of clavus, and apex of corium dull, not pruinose; median part of mesosternum and hind margin of metasternum the same, only with inconspicuous hairs.

Head exerted, more or less rhomboid in dorsal view, as long as wide. Eyes rather large, moderately prominent, not pedunculate, not reaching anterior margin of pronotum. Ocelli situated posteriad of hind margin of eyes, as far from eyes as from each other. Antenniferous tubercle close to eye, well developed. Antenna very slender, about as long as or a little longer than body, segments cylindrical (only very slightly widened towards apex), with short, hardly visible hairs. Labium reaching or surpassing middle of mesosternum. Neck narrow and relatively short, about half as wide as head.

Thorax. Pronotum distinctly divided into anterior and posterior lobe by well developed transverse impression, lateral margin distinctly emarginate between anterior and posterior lobes, anterior lobe relatively narrow, posterior lobe longer, sloped more strongly than anterior lobe. Pronotal collar slightly convex, lateral margin of pronotum very ¿ne, almost invisible, posterior margin straight. Posterior lobe of pronotum and whole of scutellum with strong, anterior lobe of pronotum with weak and scattered punctures. Scutellum triangular, longer than wide, only slightly protuberant, without Y-shaped elevation. Clavus with four rows of punctures, second row not always reaching base, often with an incomplete ¿fth row distally. Endocorium with two divergent rows of punctures, another row near apical margin; mesocorium irregularly punctate. Costal margin of corium slightly concave, apical margin hardly convex. Membrane with four veins, not forming cells. Prosternum with decumbent short hairs. Metathoracic scent gland ostiole provided with auriculate peritreme strongly curved posteriorly, situated close to coxae. Evaporatorium relatively small, occupying only medial half of metapleuron. Legs slender and very long, anterior femur very slightly thickened, more slender than vertex, on inner surface with a few short spines and some long hairs, other femora and tibiae straight, unarmed. First tarsal segment much longer than other two segments together.

Abdomen. Suture between abdominal sterna four and ¿ve oriented anteriorly, not reaching lateral margin of abdomen. Abdominal trichobothria situated as typical in Ozophorini , all spiracles ventral. Abdomen densely pubescent, and with sparse long hairs (longer than width of femur).
