Figs. 6–10  
Body length 10–11mm. Wing length 9–10 mm. General colour: Most of head orange-brown but with extensive pollinose areas on parafacial and subantennal area; face yellowish white, palest on ventral half; paracephalon paler than epicephalon. Thorax almost uniformly dull yellowish brown, proepisternum with a transverse black band just above the proepisternal setae. Abdominal tergites dark brown to black with a bluish luster.  
 Head: Frons longitudinally ridged, lower half elevated above eye with sides vertical; uniformly dull orange except for dark ocellar triangle, frontal vitta not differentiated; frontal setae very small, inner vertical seta large (orbital and outer vertical setae minute or absent; Fig. 6). Clypeus uniformly pale orange, middle part with two small stout setae and a few small setulae, clypeus covered with fine white setulae (denser on lateral portions). Lunule narrow with a few scattered black setulae, face weakly sclerotized and pale, densely microsetulose. Palpus parallel-sided, ¾ as long as clypeus, with evenly spaced small black setae. Mentum strongly setose.   
 Thorax: Notum uniformly dull yellowish brown. Both sexes with an irregular row of minute acrostichal and dorsocentral setae, 1–3 anterior dorsocentral setae usually enlarged, longer than other setae but not conspicuous. Katepisternum with a prominent vertical row of black setae and a much weaker anterior row made up of only 3–5 small black setae just above the coxa; ventral apex of katepisternum with two long thick setae and one thin seta.   
 Legs: Fore coxa with an indistinct pollinose appearance on lateral surface (created by fine white microsetulae), bare and yellowish elsewhere. Fore femur and tibia dark brown to black, tibia with a diffuse preapical yellow ring; tarsomere one of foreleg white with white setulae except for a few black preapical and apical setulae, other fore tarsomeres black; mid and hind femora grading from yellowish brown at base to dark brown at apex, with one yellow preapical band. Mid and hind tibiae brown, tarsomeres dark brown to black but tarsomere one of hind leg with dense white microsetulae ventrally.   
 Wing: Basal band restricted to anterior third of the wing, discal and preapical bands irregular and partly coalesced with each other and the apical infuscation to make a large infuscated area punctuated by about 10 more or less circular clear spots (Fig. 7). Abdomen: Tergites dark brown to black, tergites 1 and 2 fused but delineated by a band of silvery microsetulae. Tergite 1 with long pale lateral and dorsolateral setae, other tergites with small black setulae only. R 2+3 ending half as far beyond plane of dm-cu as length of dm-cu.   
 Female abdomen: Pleuron black at base, and with a dorsolateral black area starting near anterolateral margin and evenly expanding to cover entire pleuron by segment 7, ventral margin of dark area angled but straight (Fig. 9). Oviscape setulose laterally on basal half, otherwise shining blackish brown with sparse small setae (Fig. 9). Single spermatheca small, elongate, with body not distinctly differentiated from stem, with duct about 3X longer than spermatheca; paired spermathecae on a very long duct; stems long and coiled; bodies much larger, spherical with a distinct invagination (Fig. 10).   
 Male abdomen: Pleuron of segment 2 with a large, round bulge (pleural sac), densely covered with dark microtrichia. Posterolateral corner of tergite 2 with a dark, tab-like process (especially conspicuous on cleared specimens). Epandrium brown and shining basally, paler and microsetulose distally. Genital fork prominent, longer than epandrium, base of fork longer than arms. Phallus broad basally, distally tapered to a whip-like apex. Anterior spatulate part of hypandrium (hypandrial bridge) half as long as posterior hypandrial arms (Fig. 8).

 Comments. This species keys to H. perforatum in Hennig (1935), but H. perforatum has banded wings and does not have the dark part of the wing perforated by clear spots as in this species. Species with similarly patterned wings occur in the genera Cardiacephala Macquart and Planipeza Marshall, but do not appear elsewhere in Hoplocheiloma.
