Philonthus decorus
(Gravenhorst)
(
Figs 16–18
,
36–40
, 50–51, 57, 67)
Body length: 6.60–8.00 mm (mean
7.40 mm
), female
6.60–7.98 mm
(mean
7.50 mm
), male
6.90–7.40 mm
(mean
7.20 mm
); body width:
3.25–3.74 mm
(mean
3.4 mm
); female
3.25–3.74 mm
(mean
3.4 mm
); male
3.25–3.36 mm
(mean
3.31 mm
); head width:
1.77–1.95 mm
(mean
1.85 mm
), female
1.80–1.95 mm
(mean
1.89 mm
), female
1.77–1.89 mm
(mean
1.82 mm
); pronotum width:
2.08–2.21 mm
(mean
2.14 mm
), female
2.13–2.5 mm
(mean
2.32 mm
), male
2.08–2.21 mm
(male
2.20 mm
), about as broad as long; body stocky and strongly sclerotized. Head 1.1 x as long as wide (
Figs 16, 17
). Antennae distinctly protruding beyond middle of elytra (
Fig. 17
). Anterior margin of pronotum with 15–23 projections (females–9/8, 9/7,
10/9
, 12/11, 9/9, 9/10, 9/9, 10/10, 9/10, 10/10, male–8/ 8,
10/9
,
10/8
, 11/9, 8/7, 9/10 projections on sides in individuals). Wings reaching the posterior margin of 1st (morphologically 3rd) clearly visible abdominal segment (
Figs 16, 17
). Each fore, middle, and hind tibiae with 5, 9, and 5 protuberances respectively. Tarsi of hind legs reaching to, or slightly protruding beyond, posterior margin of 4th (morphologically 6th) clearly visible, abdominal segment (
Figs 16, 17
). Abdominal segments II and III almost equal in width, then abdomen gradually narrowed to the terminal segment of the body (
Fig. 18
). Abdominal segments III–VIII each with a pair of setiform projections (6 pairs in total) on sides (
Figs 16–18
). Segments III–VI with short, straight projection, segments more than 4 (4.1–4.3) x longer than projections (
Fig. 37
); segment VII with long, slightly curved projections, segment about 1.3 x as long as projections (
Fig. 36
); segment VIII with longest, moderately curved projections, almost as long as segment (
Fig. 39
). All abdominal projections on sides bearing cuticular processes (
Figs 38, 40
). Abdominal segments with microstructure as in
Fig. 39
A. Female pupa with two ventral prolongations (Fig. 50); each prolongation with tiny denticle inside near apex (Fig. 50A); terminal prolongation with tiny numerous cuticular processes in apical region (Fig. 50B). The first pair of functional spiracles relatively small, similar to second, moderately elongated, without microstructure (
Figs 17, 18
,
57
); atrophied spiracles as in
Fig. 67
.
