Key to species of Jaliscoa

1 Propodeal callus with oblique carina extending posterolaterally from spiracle (Fig. 103: arrow 2); anterior, carinate margin of femoral depression continuous ventrally as transverse carina anterior to mesocoxae (Figs 101, 102: mpc), hence setal line on anterior margin not extending to anterodorsal angle of mesocoxae (Fig. 102); antenna, legs, and usually gaster in part yellowish-orange (Figs 97, 99); propodeum with complete, sinuate plica extending to nucha, the sinuation forming variably developed but complete costula extending to median carina (Fig. 103); female with fore wing dorsally almost bare at least to apex of stigmal vein (Fig. 104)................................................................ J. nudipennis Bou č ek

- Propodeal callus uniformly convex and sculptured adjacent to spiracle (Figs 71, 84, 96); anterior margin of femoral depression and setal line extending to anterodorsal angle of mesocoxae, without transverse carina delimiting ventral region anterior to mesocoxae (Figs 66, 82, 92); antenna with at least flagellum brown, and often legs in part and gaster of female often at least dorsally dark (Figs 65, 70, 91); propodeum with plica often distinct only anteriorly and/or with costula incomplete or developed as only angulate or rounded margin (Figs 71, 84, 96); female with fore wing dorsally sometimes extensively setose beyond speculum (Figs 80, 93, 110)....................................................................... 2

2(1) Pronotal collar with anterior margin sublaterally (anterior of notaulus) almost right-angled emarginate (Fig. 81: arrow) and variably distinctly reflexed above level of dorsal surface of collar as transverse, sculptured margin or ridge (Fig. 82: arrow); legs more or less light coloured beyond coxae, though femora usually variably darker orange compared to yellowish-white tibiae and tarsi (Figs 73–76); propodeum without plical carina (Figs 83, 84)........................... J. grandis (Burks)

- Pronotal collar with anterior margin sublaterally more smoothly sinuate (Fig. 90) and usually without evident anterior margin; legs usually with at least femora extensively dark brown to almost black similar to mesosoma (Fig. 91), though sometimes similar to above; propodeum sometimes with plical carina, at least posteriorly within nuchal furrow (Figs 95, 96)......... 3

3(2) Propodeum without any indication of plical carina posterior of anterolateral plical depression, including absence from nuchal furrow (Fig. 71); tibiae yellowish-white to white (Figs 65, 70) and fore wing of female, excluding admarginal setae, essentially glabrous to level at least about equal with apex of stigmal vein (Fig. 72); malar space with at least fine, though sometimes obscure malar sulcus (Fig. 69: arrows), and comparatively short (Figs 67–69), in lateral view at most 0.6× width of eye............................................................................................ J. bouceki n. sp.

- Propodeum usually with at least a short carina within nuchal furrow and sometimes with variably distinct plical carina extending posterior of anterolateral plical depression (Figs 95, 96, 109), but if not then one or more of above features different, usually with at least meso- and/or metatibia quite obviously bicolored (with darker orange to brown region subbasally to medially) (Fig. 91) and/or female with fore wing extensively setose behind marginal vein, posterobasally in oblique line toward medial fold from about middle of stigmal vein or marginal vein (Figs 93, 110), and malar space either without malar sulcus (Figs 88, 107) or greater than 0.6× width of eye (Figs 85, 86)...........................................4 [ hunteri -complex]

4(3) United States through Central America and South America; body length variable, but malar space greater than 0.6× width of eye............................................................................... J. hunteri (Crawford)

- Caribbean islands (St. Vincent and Grenada); body length only about 3.2 mm and malar space at most 0.6× width of eye....................................................................................... J. vulgaris (Ashmead)
