Description. FEMALE (habitus: Figs 64, 65 ). Length = 1.7–3.2 mm. Head. Face ( Fig. 67 ) with clypeus more or less uniformly, longitudinally, finely striate to strigose, and finely, obliquely, coriaceous-alutaceous for at least half distance to eye and then meshlike coriaceous or only very shallowly coriaceous-reticulate adjacent to eye, but with parascrobal region vertically striate-alutaceous, scrobal depression meshlike reticulate, and supraclypeal region meshlike reticulate to partly coriaceous ( Fig. 69 ); malar space with fine, though sometimes obscure malar sulcus extending between lower orbit and oral margin at posterior limit of malar depression ( Fig. 69 : arrows), and 0.32–0.40× eye height ( Fig. 67 ) and 0.44–0.59× eye width. Antenna more or less uniformly yellowish or pedicel and/or flagellum yellowish-brown to light brown ( Fig. 64 ).

Mesosoma. Tegula yellow. Pronotal collar abruptly angled relative to collum ( Fig. 66 ), but not raised or carinate anteriorly, and laterally shallowly sinuate (cf. Fig. 90 ). Mesopectus ( Fig. 66 ) with short, horizontal ridge or at least abrupt angulation at level of base of mesocoxa, but carinate anterior margin of femoral depression not continuous ventrally anterior to mesocoxa and setal line extending ventrally close to anterior angle of mesocoxa. Fore wing ( Fig. 72 ) with 0–3 setae in costal cell ventroapically; disc (excluding admarginal setae) essentially glabrous to about apex of stigmal vein (membrane behind marginal vein usually with variably distinct spots representing remains of setal pores), though dorsally sometimes with a couple of setae proximal to stigmal vein and variably extensively and distinctly setose beyond level of stigmal vein, and ventrally with distinct setae beyond level of stigmal vein posteriorly to medial fold, the medial fold with a line of distinct setae extending further basally; admarginal area with 7–14 setae usually arranged in 1 or 2 irregular rows; marginal fringe usually complete (rare absence in museum specimens likely result of abrasion); smv: mv: pmv: stv about 3.5–4.1: 2.2–2.7: 1.7–2.0: 1.0. Legs ( Fig. 65 ) sometimes with one or more femora quite distinctly brown except basally and apically, more often with femora yellowish-orange to orange, but at least tibiae and tarsi more yellowish-white to white. Propodeum ( Fig.71 ) with callus uniformly convex, without oblique carina lateral of spiracle; without plical carina, even posteriorly within nuchal furrow; plical region usually with distinct, transverse angulation evenly recurved anteromesally from basal plical depression so as to delineate strongly transverse, depressed anterior panel, the median region intersected by median carina that extends to nucha, and medially with anterior panel at most as long as posterior panel and at least slightly shorter than nucha.

Metasoma. Gaster ( Figs 64, 65 ) often not contrasting conspicuously in color with mesosoma, variably dark brown to almost black with metallic lustres dorsobasally on Gt1 and basolaterally on other terga, but sometimes orangey-brown to light brown with limited metallic lustre laterally; lanceolate, length about 1.9–3.4× as long as wide (typically more elongate-slender in air-dried specimens with collapsed gaster); Gt2–Gt4 with posterior margins variably distinctly emarginate, but at most Gt2 and Gt3 with very short, white, mediolongitudinal line posteriorly; syntergum at least about as long as wide and with about apical half setose; cercus conical but short, not distinctly digitiform.

MALE (habitus: Fig. 70 ). Similar to female except as follows: gaster with large, subbasal, yellowish region ( Fig. 70 ); fore wing with up to 6 setae ventroapically in costal cell, disc always extensively setose except for oblique speculum extending to base of stigmal vein, and with up to 21 admarginal setae in 1–3 rows.

Biology. Hosts and plant associates unknown, but undoubtedly a parasitoid of Curculionidae (Coleoptera) based on known host associations of other Jaliscoa species.

Discussion. Individuals of J. bouceki are very similar to those differentiated below as the hunteri -complex ( J. hunteri and J. vulgaris ) except for the features given in the key. Complete absence of any indication of a plical carina ( Fig. 71 ) differentiates J. bouceki from most hunteri -complex individuals ( Figs 95, 96 ). However, some J. hunteri lack a plical carina or have this developed only very slightly such that it can be easily overlooked ( Fig. 109 ) without proper illumination and magnification. In such instances a combination of three features—tibial colour, fore wing setal pattern, and malar space structure distinguish individuals. Females of J. bouceki always have the fore wings essentially glabrous behind the marginal vein ( Fig. 72 ) and both sexes have the tibiae yellowish-white to white ( Figs 65 , 70 ). Females recognized here as J. vulgaris have yellowish-white tibiae similar to J. bouceki as well as a relatively short malar space, but lack a malar sulcus ( Figs 105, 107 ) and have the fore wings extensively setose behind the marginal vein ( Fig. 110 ). Individuals of J. hunteri are more variable, but typically at least the meso- and/ or metatibiae are banded with an obviously darker orange to brown band subbasally to mesally ( Fig. 91 ) and/or the fore wings are extensively setose behind the marginal vein ( Fig. 93 ), but if not then the malar space not only lacks a malar sulcus but is at least 0.6× as long as the width of an eye ( Fig. 88 ). Males of J. bouceki and those of the hunteri -complex have similarly, extensively setose fore wings and thus can be more difficult to differentiate. Based on the above features, I include in the type series one male from Tlanchinol, Mexico that was collected the same time and place as one female and one male I identify is J. hunteri .
