Holloway ( 1♀ , AMS ) . Redescription Male ( Figs 1, 2, 6 ). Body length 3.0– 4.5 mm . Anepisternal disc present. First flagellomere recessed dorsally and lobate ventrally. Bristles dark brown. Arista pubescent. Vibrissa short and straight. Ocellar bristle relatively stout and longer than tubercle. Two dorsocentral bristles. Gena high and sharply incurved medially at mid-height. Face and buccal cavity evenly curved and velvety. Frons brown on posterior 2 ⁄ 3 (lateral and posterior margins paler); back of head dark brown; occiput and posteroventral corner of gena dark brown; face lighter dorsally; gena silvery tomentose above genal bristles; anterior 2 ⁄ 3 of frons pilose. Thorax dark brown. Legs yellow except as follows: mid coxa brown dorsally; hind coxa light brown; fore femur with large, dark anterodistal and posterodorsal spots (usually somewhat confluent); fore tarsi brownish on distal two or three segments; hind femur somewhat dusky on outer surface apically; hind tibia brown on basal 1 ⁄ 3 ; mid and hind femora sometimes brownish dorsomedially; mid femur and mid and hind tibiae sometimes with wide central band; fore coxa sometimes with minute brownish spot on dorsal margin, and gena and venter of face dusky. Fore tarsi cylindrical in cross section. Abdomen dark brown. M 1+2 ratio 6.5–7.3. Wing clouded on distal half of anterior margin; veins, excluding costa and R 2+3 , surrounded by light infuscation. Halter white with base and side of stalk infuscated. Female . As described for male except as follows: fore tarsi dark brown, high and laterally flattened (height sharply decreasing past second segment); fore femur with outer-distal spot absent or fused to inner spot; fore tarsi dark brown; mid coxa brown on outer-dorsal half; fore tibia sometimes white with base dark brown; mid tibia sometimes mottled medially; apex of mid and hind femora and base of mid tibia variably infuscated; base of hind tibia brown; frons pilose anteromedially; first flagellomere dark along anterior and dorsal margins, or entirely dark excluding basal margin; gena and venter of face dusky; tergites 2–5 sometimes yellow on anterior 2 ⁄ 3 , or with anterior half of tergite 2 and all of tergites 3–5 yellow; wing without light infuscation around veins. Two non-type females with fore tarsi only slightly modified, fore tibia entirely light yellow, apex of fore femur brown, hind knee brown and face and gena entirely reddish-brown. Male terminalia ( Figs 32–34 ). Epandrium deeply excavated on anterior margin, continuous with posterior margin of large hypandrium+pregonite. Cerci widest subapically and emarginate. Surstylus long and thin (narrowest subapically) with few anterodistal setulae and several innerdistal tubercles. Hypandrium+pregonite with single large basal lobe with anterodistal and medial setulae, two stout medial bristles and stout posterodistal bristle on inner face. Distiphallus with one rib short, thin and tapered, and one rib large and elaborate apically: with thin posteriorly-directed process, one wider anteriorly-directed process and elongate bifid distal process. Female terminalia (Fig. 93). Spermatheca with several shallow basal wrinkles and many minute medial tubercles; apex broadly rounded with apical invagination small and offset. Ventral receptacle and flagellum not visible.
