Key to species of Procas Stephens, 1831
1 Antennal funicle segment 3 less than half as long as segment 1; elytra usually with 1–3 white spots at top of declivity; setae on female sternite 8 small (c. 0.03 mm long). NonEuropean ............................................................................................................... 2
Antennal funicle segment 3 at least half as long as segment 1; elytral declivity never with white spots; setae on female sternite 8 large (<0.1 mm long). Europe, North Africa, Middle East ....................................................................................................... 3
2 Antennal funicle segment 7 transverse; male sternite 8 with processes parallel or weakly diverging, merging with broad median column and often fused together in basal half or more of their lengths ( Figs 96–99 View FIGURES 86–99 ); female sternite 8 with pigmented area expanded apically (posteriorly)( Figs 41–43 View FIGURES 39–43 ); spematheca with glandlobe variable in shape, gland variable in size ( Figs 68–73 View FIGURES 65–73 ). North America ............................... lecontei
Antennal funicle segment 7 quadrate; male sternite 8 with processes elongate, strongly diverging, distinct from slender tapering median column ( Figs 92–95 View FIGURES 86–99 ); female sternite 8 with pigmented area expanded basally (anteriorly)( Figs 39, 40 View FIGURES 39–43 ); spermatheca with glandlobe usually tapering and weakly expanded at apex, gland small (c. 0.2 mm long)( Figs 65–67 View FIGURES 65–73 ). Russian Far East, Japan, NE China, Korea..................... biguttatus
3 Pronotum, on either side of midline, with a variable and ill defined area of low, setiferous granules, often obscured by their setae ( Figs 13, 14 View FIGURES 9–14 ); head usually with small frontal pit; antennal funicle segment 2 usually only slightly longer than 3; male sternite 8 with processes more or less curved ( Figs 83–85 View FIGURES 74–85 ); female sternite 8 with pigmented areas distinctly separate ( Figs 21–23 View FIGURES 21–26 ); spermatheca with glandlobe more or less cylindrical and slightly expanded at apex ( Figs 44–47 View FIGURES 44–50 ). (Scutellum often covered with white setae (appearing white); clothing setae rather coarse (sometimes markedly so).) United Kingdom, NW Spain ........................................................................ granulicollis
Pronotum more or less uniformly punctate on disc (sometimes with setiferous granules near sides)( Figs 11, 12 View FIGURES 9–14 ); head usually without a frontal pit; antennal funicle segment 2 usually distinctly longer than 3; male sternite 8 with processes more or less straight ( Figs 74–82 View FIGURES 74–85 ); female sternite 8 with pigmented areas fused or narrowly separated ( Figs 24–38 View FIGURES 21–26 View FIGURES 27–34 View FIGURES 35–38 ); spermatheca with glandlobe variable but not expanded at apex ........... 4
4 Rostrum finely and evenly punctate, seldom with any trace of a median carina but usually with a very fine linear carinula near apex ( Fig. 9 View FIGURES 9–14 ); sides of rostrum widening smoothly at antennal insertions (in dorsal view); elytral setae mostly very small and recumbent, with a few (sometimes very few) much larger scattered semierect white setae, especially on declivity; punctures on sides of prothorax (above fore coxae) and on metepisterna containing simple linear setae; male sternite 8 with short processes (<0.1 mm long)( Figs 88–91 View FIGURES 86–99 ); female sternite 8 broad, somewhat straightsided and angular anteriorly, spiculum broad ( Figs 35–38 View FIGURES 35–38 ). (Tibiae 2 and 3 with prominent circlet of white setae at base; spermatheca with glandlobe small, strongly reflexed ( Figs 59–64 View FIGURES 59–64 ).) North Africa, Atlantic and Mediterranean islands, Greece (?). ...................... ........................................................................................................................ armillatus
Rostrum with coarser, ovate punctures, their interspaces tending to form longitudinal rugulae, with a partial median carina but no preapical carinula ( Fig. 10 View FIGURES 9–14 ), sides widening somewhat abruptly at antennal insertions; elytral setae larger and more nearly uniform in size; setae in punctures on sides of prothorax and on metepisterna, in part, bifid or multifid; male sternite 8 with long processes (0.1–0.2 mm)( Figs 74–82 View FIGURES 74–85 , 86, 87 View FIGURES 86–99 ); female sternite 8 ovate, spiculum slender ( Figs 24–34 View FIGURES 21–26 View FIGURES 27–34 ) ........................................ 5
5 Male sternite 8 with processes strongly divergent (sometimes almost in a line), their pigmented elements close together at narrow apex of median column, which they enter ( Figs 86, 87 View FIGURES 86–99 ); spermatheca with glandlobe very strongly reflexed ( Fig. 48 View FIGURES 44–50 ). (Tibiae 2 and 3 with indistinct circlet of white setae at base.). Spain............................. michaelis
Male sternite 8 with processes usually less strongly divergent, their pigmented elements clearly separate at broad apex of median column, which they seldom enter ( Figs 74–82 View FIGURES 74–85 ); spermatheca with glandlobe only weakly reflexed ( Figs 51–58 View FIGURES 51–58 )....
