Philonthus debilis (Gravenhorst)

((Figs 13–15, 33–35, 49–49B, 56, 60, 68–70)

Body length: 3.20–3.30 mm; body width: 1.35–1.38 mm; head width: 0.66–0.77 mm; pronotum width: 0.90–0.98 mm; 1.1 x as broad as long; body rather slender and relatively weakly sclerotized. Head almost as long as wide (Figs 13, 14). Antennae reaching to middle of elytra length as in B. fimetarius (Figs 2, 14). Margin of pronotum with 8 or 10 projections (5/5, 4/4, projections on sides in individuals). Wings slightly protruding on the posterior margin of 1st (morphologically 3rd) clearly visible, abdominal segment (Figs 13, 14). Each fore, middle, and hind tibiae with 4–5, 9, and 4 protuberances respectively. Tarsi of hind legs reaching or protruding the middle of 4th (morphologically 6th) clearly visible abdominal segment length (Figs 13, 14). Abdominal segments II–IV almost equal in width, then narrowed to the terminal segment of the body (Fig. 15). Abdominal segments III–VIII each with a pair of setiform projections (6 pairs in total) on sides (Figs 13–15). Segments III–VII 1.2–1.4 x as long as projections (Figs 13–15); projections of segment VIII usually curved, at least as long as segment (Figs 33, 34). All abdominal projections on sides bearing sparse cuticular processes (Fig. 35). Abdominal segments with microstructure as in Fig. 34 A. Female pupa with two well-developed ventral, elongated, straight prolongations (Fig. 49); ventral and terminal prolongation with tiny cuticular processes (Figs 49A, 49B). The first pair of functional spiracles distinctly narrowed apically (Figs 56, 60) with reticulate microstructure; atrophied spiracles as in Figs 68–70.
