Redescription. Male. Length: body, 8.0–10.0 mm; wing, 6.5–8.5 mm. Head ( Figs 13, 15View FIGURES 13–24). Upper frons slightly narrower than widest margin of frontal callus. Frontal callus margin slightly divergent towards face. Aristalike terminal flagellomere with four thin setae basally. Thorax. Legs mostly yellow, except mid and hind coxae, apical half of mid and hind femora, and at least all apical tarsomeres dark brown. Wing ( Figs 25–26View FIGURES 25–28). R 2+3 originating beyond r–m, at a distance as long as r–m ( Fig. 33View FIGURES 33–38). Proximal branch of M 1+2 slightly shorter than distal branch of M 1+2. Alula with microtrichia along anterior half, rarely few sparse microtrichia apically ( Fig. 39View FIGURES 39–44). Abdomen ( Fig. 45View FIGURES 45–55). Elongate, at least twice as long as wide, widest at about third to fourth segments; distinctly metallic green on tergites, dark brown with green to coppery reflections on sternites; long yellow pilosity laterally on tergites 1–2; shorter golden pilosity densely covering most of tergites 3–5 and sternites. Terminalia ( Figs 56– 58View FIGURES 56–58, 86–89View FIGURES 86–95). Genital capsule as wide as high, its posterior margin rounded dorsally; medial process of synsternite weakly developed ( Fig. 89View FIGURES 86–95); anterior end of gonocoxal apodeme and anterior end of phallus at same level as anterior margin of genitalia. Epandrium slightly wider than long ( Fig. 56View FIGURES 56–58).

Female. As for males, except as follows. Length: body 7.0–10.0, wing 6.5–9.0. Head ( Figs 14, 16View FIGURES 13–24). Upper frons nearly as wide as frontal callus. Lateral area of upper frons as wide as medial area. Thorax. Distal half of all femora dark brown (rarely basal two-thirds darker). Terminalia ( Figs 62–63View FIGURES 62–65). Genital fork widest medially ( Fig. 63View FIGURES 62–65), anterior arm clearly triangular; long projections of posterior bridge widely spaced; posterolateral process very slender dorsally.

Biology. Male post-coupling courtship of this species was described by Eberhard (1988).

Geographic distribution. Mexico (Chiapas, Durango, Guerrero, Jalisco, Michoacán, Morelos, Nayarit, Oaxaca, Puebla, Sinaloa, Sonora, Zacatecas)  , Guatemala ( Guatemala, Chimaltenango, Sacatepéquez, Sololá)  , El Salvador (La Libertad, San Salvador)  , Costa Rica (Cartago, Heredia, Puntarenas, San José) ( Fig. 130View FIGURE 130)  .

As commented by James & McFadden (1982), this species seems to occur at higher elevations, often above 1000 meters.

Comments. Some male and female specimens, mainly from Costa Rica (see Figs 107View FIGURES 106–111, 113View FIGURES 112–117, 121View FIGURES 120–125), El Salvador and Guatemala, differ in having darker legs, exemplified in the femora and in the distal half of all tibiae antero-dorsally that are dark brown. Females may also have the last two tarsomeres (not just the apical segment) of the legs dark brown instead, and paler males ( Mexico, Figs 106View FIGURES 106–111, 112View FIGURES 112–117) may be without dark brown spots on the fore femur.

One female specimen from Mexico (Tuxtepec, Oaxaca) deposited in WSU was identified as H. silvestris  (determination label by James 1981), but this same specimen was included in James & McFadden’s (1982) revision as H. nigrifemorata  . It is here considered to be H. nigrifemorata  since all terminal tarsomeres are black.
