Key to the species of Picromerus Amyot and Serville View in CoL View at ENA from China
1 Pronotal humeral angle sharp angulated, with a subapical prominence or tooth and same color as the pronotal disc......... 2
- Pronotal humeral angle obtuse angulated, without a subapical prominence or tooth, color different from disc............. 5
2 Connexivum entirely black; the apex of humeral angle with an obvious tooth ( Fig. 23 View FIGURES 19–26 ); body dorsum black, hardly with yellow spots; membrane passing the end of abdomen slightly; aedeagus with one pair of basolateral conjunctival lobes, proximal branch small, short, membranous; distal branch long, narrow, with sclerotized apex; apical conjunctival lobe short and bifurcate, stretch out from apical part of theca (Fig. 59).................................................... P. griseus
- Connexivum black and yellow, humeral angle slightly bifurcate, posterior branch only a prominence (e.g. Fig. 24 View FIGURES 19–26 )......... 3
3 The anterolateral margin of pronotum with a broad yellow-white margin, anterior branch of pronotal humeral angle very long and the apex slightly curved ( Fig. 24 View FIGURES 19–26 ); head above and beneath, anterolateral pronotal submargin, incisures of connexivum and ventral surface of pronotal humeral angles, lateral area of sternum more or less marked with metallic-green shades................................................................................................ P. viridipunctatus
- The anterolateral margin of pronotum without such broad yellow-white margin, nearly same color with other part of pronotum .................................................................................................... 4
4 Buccula relatively narrow, outer margin straight, with 2–3 rows of punctures ( Fig. 13 View FIGURES 13–18 , arrow noted); lateral sides of the ventral abdomen evenly scattered with finely black spots, not formed into black belts ( Fig. 15 View FIGURES 13–18 ); paramere slim and long, apex hooked and sharp( Figs. 37 View FIGURES 27–41 , 52 View FIGURES 42–56 ); aedeagus with one pair of basolateral conjunctival lobes, proximal branch small, short, membranous; distal branch long, narrow and with sclerotized apex; apical conjunctival lobe long, bifurcate (Fig. 57)............ P. bidens
- Buccula relatively broad, outer margin curved, with 4–6 rows of punctures ( Fig. 14 View FIGURES 13–18 , as arrow noted); lateral sides of the ventral abdomen with series of black spots, sometimes formed into black belts ( Fig. 16 View FIGURES 13–18 ,); paramere wide in basal part, apex hooked and digitiform ( Fig. 38 View FIGURES 27–41 , 53 View FIGURES 42–56 ); aedeagus with one pair of basolateral conjunctival lobes, proximal branch small, semicircled; distal branch long, narrow and with sclerotized apex; apical conjunctival lobe long and bifurcate, stretch out from apical part of theca obviously (Fig. 58).......................................................................... P. lewisi
5 Head black, center with a broad mesial yellow-brown band, including clypeus and vertex, continuing to base of head; anterolateral pronotal margins thick, with sparse, obtuse tooth; the calli outlined in black, with some black irregular short band radiating backward; dorsal surface of body intumescent, not flat ( Fig. 17 View FIGURES 13–18 ); humeral angles black, shortly porrect ( Fig. 25 View FIGURES 19–26 )................................................................................................ P. fasciaticeps
- Head yellowish uniformly; anterolateral pronotal margins relatively thin and with small obtuse teeth; the back margin of calli outlined in black unclearly; dorsal surface of body flat, not intumescent ( Fig. 18 View FIGURES 13–18 ); humeral angles elevated, pale and long ( Fig. 26 View FIGURES 19–26 ).................................................................................. P. elevatus sp. nov.
