Philonthus carbonarius (Gravenhorst)

(Figs 10–12, 26–32, 47–48A, 55, 66)

Body length: 4.29–4.95 mm (mean 4.7 mm), female 4.57–4.95 mm (mean 4.81 mm), male 4.29–4.73 mm (mean 4.60 mm); body width: 1.93–2.20 mm (mean 2.00 mm), female 2.00– 2.22 mm (mean 2.1 mm), male 1.91–2.10 mm (mean 2.00 mm); head width: 1.06–1.19 mm (mean 1.13 mm); pronotum width: 1.39–1.65 mm (mean 1.53 mm), 1.1 x as broad as long; body rather stocky and weakly sclerotized. Head about 1.2 x as long as wide (Figs 10, 11). Antennae protruding middle of elytra length (Fig. 11). Anterior margin of pronotum with 10–13 projections (females–5/5, 7/6, 6/6, 7/6, 5/6 projections, males–6/6, 6/6, 5/6, 6/6, 6/6, 6/6, 6/6 projections on sides in individuals). The wing length as in G. osseticus and P. atratus (Figs 4, 5, 7, 8, 10, 11). Each fore, middle, and hind tibiae with 1, 9, and 4 protuberances respectively. The length of hind legs as in P. a t r a t u s (Figs 7, 8, 10, 11). Abdominal segments II–IV almost equal in width, than narrowed to the terminal segment of the body (Fig. 12). Abdominal segments III–VIII each with a pair of setiform projections (6 pairs in total) on sides (Figs 10–12). Segments III–VI more than four (4.3–4.5 x) as long as projections (Figs 28, 31); projections on segments VII and VIII, 3– 4 x longer than on the other segments; projections on segment VII only about 1.5x shorter than segment, projection on segment VIII curved, slightly longer than segment (Figs 26, 30). All abdominal projections on sides bearing cuticular processes (Figs 27, 29, 32). Abdominal segments with microstructure as in Fig. 26 A. Female pupa with two well-developed ventral, elongated, straight prolongations (Fig. 47); sternite IX of male pupa as in Fig. 48; ventral and terminal prolongation with tiny cuticular processes (Figs 47A, 48A). The first pair of functional spiracles slightly narrowed to the apex, with strongly-marked reticulate microstructure (Figs 11, 12, 55); atrophied spiracles as in Fig. 66.
