Key to Nearctic Nephrocerus View in CoL View at ENA

External characters work well to separate the species groups of Nephrocerus and species of the slossonae group. Males of the daeckei group must be dissected for specific identification; females of this group are very difficult to distinguish and are unknown for N. woodi sp. nov.

1. Coxae with yellow to pale brownish hairs contrasting little with yellow legs; abdomen with hairs all yellow ..................................................................... slossonae View in CoL group … 2

— Coxae with black hairs contrasting sharply with yellow legs; abdomen with hairs mostly dark brown to black ................................................................ daeckei View in CoL group ... 4

2. Scutellum View in CoL shining black medially with yellow around posterior and lateral margins ( Fig. 1 View FIGURE 1 A); proepisternum entirely bright yellow ( Fig. 1 View FIGURE 1 C); abdominal tergite 1 entirely yellow laterally ( Fig. 1 View FIGURE 1 C); male hind tibia with ventral patch of specialized bristles ( Fig. 2 View FIGURE 2 A); left surstylus of male with distinctive hook ( Fig. 3 View FIGURE 3 A, C, D); right surstylus with upper lobe short, quadrate ( Fig. 3 View FIGURE 3 B); female ovipositor short, stubby ( Fig. 4 View FIGURE 4 A) ... ................................................................................ Nephrocerus acanthostylus View in CoL sp. nov.

— Scutellum completely yellow, rarely slightly darkened basally or entirely brown (never black with yellow margins) (cf. Fig. 1 View FIGURE 1 B); at least anterior edge of proepisternum brown to black (cf. Fig. 1 View FIGURE 1 D, E); abdominal tergite 1 always at least partly brown laterally (cf. Fig. 1 View FIGURE 1 E); male hind tibia with circlet of bristles ( Fig. 2 View FIGURE 2 C) or elongate apical bristles on outer edge ( Fig. 2 View FIGURE 2 B), but without ventral specialized bristles; left surstylus of male simple ( Figs 7 View FIGURE 7 A, C, D or 11A, C, D); right surstylus with upper lobe projecting and deflected ventrally at 90 degrees ( Figs 7 View FIGURE 7 B or 11B); female ovipositor short and stubby ( Fig. 4 View FIGURE 4 E) or long and narrow ( Fig. 4 View FIGURE 4 C) ........................................................... 3

3. Hind tibial apex with circlet of stiff yellow bristles all about the same length ( Fig. 2 View FIGURE 2 C); epandrium narrow (ratio of width to length 1.1–1.4 (JSS#11412 = 1.6):1) ( Fig. 11 View FIGURE 11 C, D); right surstylus with upper lobe uniformly tapering ( Fig. 11 View FIGURE 11 B); middle lobe stubby, with rounded tip and curving medial edge, with no similar structure on left surstylus ( Fig. 11 View FIGURE 11 C, D); ovipositor short, stubby, 0.9 to 1.1 mm long ( Fig. 4 View FIGURE 4 E) ........................... ...................................................................................... Nephrocerus slossonae Johnson View in CoL

— Hind tibial apex with long, stiff yellow bristles restricted to outer edge of tibia, these bristles over twice length of adjacent bristles ( Fig. 2 View FIGURE 2 B); epandrium very broad (ratio of width to length 1.60–2.00:1) ( Fig. 7 View FIGURE 7 C, D); right surstylus with upper lobe broad basally, abruptly narrowing ( Fig. 7 View FIGURE 7 B); middle lobe broad, straightsided, sharply pointed, with a similar structure on left surstylus ( Fig. 7 View FIGURE 7 C, D); ovipositor long, narrow, sharply upcurved, 1.1–1.3 mm long ( Fig. 4 View FIGURE 4 C) .........
