Pseudatelus Linnavuori

Type Species: Pentatoma spinulosa Palisot de Beauvois, 1807, by original designation.

Tribal Placement: Linnavuori (1982) originally included this genus in the Halyini.

Comments: When Linnavuori (1982) described this genus, he effectively transferred all but three species into. On p. 62, he states: "Except for Atelocera armata Lap., A. darfurensis Lv. and A. serrata (F.), apparently all other "Atelocera" species belong, in fact, to Pseudatelus." Linnavuori (1982) provided a key to the West and Central African species, which accounted for about one-third of the species.

Key to West & Central African Species of Pseudatelus (modified from Linnavuori, 1982)

1 Anterolateral margins of pronotum nearly straight	2
- Anterlolateral margins of pronotum distinctly insinuated	3

2(1) Length 14-15 mm; head 0.9-1.0 times as long as broad; upper surface with distinct pale mottling; paratergites with broad pale spot in middle; venter sulcate only basally	spinulosus (Palisot de Beauvois)
- Length 17.5-18.5 mm; head acutely triangular, 1.16-1.20 times as long as broad; dark, upper surface with scanty pale mottling; paratergites with small pale lateral spot; venter deeply sulcate to fifth visible sternite	obscurus (Dallas)

3(1) Very large, length 18-19.5 mm; head very acute, 1.16-1.30 times as long as broad; posterior part of pronotum with deep, strongly shiny, smooth sublateral depressions	latus (Westwood)
- Smaller species; head shorter and broader, fairly blunt apically as in spinulosus; sublateral depressions on pronotum shallower, rugose and distinctly punctate	4

4(3) Numerous conspicuous pale callosities on pronotum, scutellum, and elytra; membrane (of male) roundedly truncate apically	sticticus (Westwood)
- Upper surface with small and sparse pale callosities; membrand (of male) insinuated apically	limatus (Germar)
