Gabrius osseticus (Kolenati)

( Figs 4–6 , 19–20 , 43–44A, 53, 58, 63, 64)

Body length: 3.70–4.0 mm (mean 3.90 mm); body width: 1.40–1.80 mm (mean 1.60 mm); head width: 0.7–0.8 mm (mean 0.8 mm); pronotum width: 1.3–1.6 mm (mean 1.5 mm), about as broad as long; body stocky, moderately and weakly sclerotized. Antennae not extending to middle of elytra length ( Fig. 5 ). Anterior margin of pronotum with 10–12 projections (5/5, 5/5, 5/6, 6/6, 6/6 projections on sides in individuals). Wings protruding on the posterior margin of 1st (morphologically 3rd) clearly visible, abdominal segment as in P. atratus and P. carbonarius ( Figs 4, 5 , 7, 8, 10, 11 ). Each fore, middle and hind tibiae with 5, 9, and 4 protuberances respectively. Tarsi of hind legs almost reaching to half of the length of 4th (morphologically 6th) clearly visible abdominal segment ( Figs 4, 5 ). Abdomen moderately and gradually widened from segment II to IV and narrowed to the terminal segment of the body ( Fig. 6 ). Abdominal tergites with microstructure ( Fig. 19 A). Abdominal segments VII and VIII each bearing a pair of setiform projections on sides ( Figs 4–6 ). Abdominal segments VII about 1.3 x longer than projections ( Fig. 19 ); abdominal segments VIII almost as long as projections ( Fig. 20 ). Terminal sternite of female pupae with two well developed ventral, elongated, and slightly curved inside prolongations (Figs 43, 43A) or short denticles (Figs 44, 44A). Male pupa with sternite IX very similar in structure to B. fimetarius (Fig. 42); ventral and terminal prolongation with sharp cuticular processes apically (Figs 43A, 43B). The first pair of functional spiracles transverse, distinctly wider than long ( Figs 53, 58 ); atrophied spiracles as in Figs 63, 64 .
