Philonthus debilis (Gravenhorst)  

(( Figs 13 –15 View FIGURES 13 – 18 , 33–35 View FIGURES 19 – 40 , 49– 49 B, 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 View FIGURES 13 – 18 ). Antennae reaching to middle of elytra length as in B. fimetarius   ( Figs 2 View FIGURES 1 – 6 , 14 View FIGURES 13 – 18 ). 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 1 st (morphologically 3 rd) clearly visible, abdominal segment ( Figs 13, 14 View FIGURES 13 – 18 ). Each fore, middle, and hind tibiae with 4 –5, 9, and 4 protuberances respectively. Tarsi of hind legs reaching or protruding the middle of 4 th (morphologically 6 th) clearly visible abdominal segment length ( Figs 13, 14 View FIGURES 13 – 18 ). Abdominal segments II –IV almost equal in width, then narrowed to the terminal segment of the body ( Fig. 15 View FIGURES 13 – 18 ). Abdominal segments III –VIII each with a pair of setiform projections (6 pairs in total) on sides ( Figs 13–15 View FIGURES 13 – 18 ). Segments III –VII 1.2–1.4 x as long as projections ( Figs 13–15 View FIGURES 13 – 18 ); projections of segment VIII usually curved, at least as long as segment ( Figs 33, 34 View FIGURES 19 – 40 ). All abdominal projections on sides bearing sparse cuticular processes ( Fig. 35 View FIGURES 19 – 40 ). Abdominal segments with microstructure as in Fig. 34 View FIGURES 19 – 40 A. Female pupa with two well-developed ventral, elongated, straight prolongations (Fig. 49); ventral and terminal prolongation with tiny cuticular processes (Figs 49 A, 49 B). The first pair of functional spiracles distinctly narrowed apically ( Figs 56, 60 View FIGURES 52 – 70 ) with reticulate microstructure; atrophied spiracles as in Figs 68–70 View FIGURES 52 – 70 .
