Description
Male (Fig. 4a, b, c), 9 mm. Head (Fig. 4b): frontal vitta dark black, slightly tapered apically to twice the width of the ocellar triangle, parafrontal 1/2 as wide as frontal vitta; frontal bristles arise no lower than level of first antennal segment; antennae black; frontoorbital plate silvery-gold turning to black apically; parafacial silvery to slightly gold tinged; palpi black gray; gena 1/8 height of head. Thorax (Fig. 4a): yellow when viewed dorsally with four longitudinal black vittae, these appear fused throughout their length with only slight separation apparent; appearing as two indistinct blotches covering 2/3rds of thorax postsuturally; three postsutural dorsocentral bristles; scutellum bearing white or yellowish pruinosity only at apex (occupying less than 1/5th of total area); 3 pairs of scutellar marginal bristles; subapical scutellars widely divergent, lateral scutellars reduced, almost half the length of the subapicals, these closer to apex, than to basal scutellars; legs black. Wings: pale smoky grayish in color, with one bristle arising at the joint between R1 and R2+3. Abdomen (Figs 1a, 4a): abdominal tergites dark velvety black, with bright, yellow bands covering less than 1/3rd of tergal surface arising at the margins of between the abdominal tergites, these bands not wrapping around to the underside; bright yellow bands straddling the margin between tergites ST1+2, T3, and the anterior margin of T4; tergal bands not possessing a sharp mid-dorsal peak rather appearing flat.
Female (Fig. 4d, e, f), 4 mm. Head (Fig. 4e): frontal vitta dark tawny, parallel sided apically equal to twice the width of the ocellar triangle, parafrontal 1.5 times as wide as frontal vitta; frontal bristles arise no lower than level of first antennal segment; proclinate orbital bristles present; antennae light black with orange present at base of first flagellomere; frontoorbital plate entirely gold; parafacial narrow, silvery to slightly gold tinged; palpi light gray at base, with orange tips, slightly haired along upper surface; gena 1/10 height of head. Thorax (Fig. 3d): yellow when viewed dorsally with four longitudinal black vittae, these becoming remaining separate postsuturally, appearing as four distinct lines covering just over 1/2 of thorax postsuturally; three postsutural dorsocentral bristles; scutellum bearing white or yellowish pruinosity over half of its area; scutellar bristles similar to males. Wings: pale smoky grayish in color, with one bristle arising at the joint between R1 and R2+3. Abdomen (Figs 2a, 4d): pointed downward apically so as to appear strongly curved; abdominal tergites dark velvety black, with dull, grayish bands covering at least 1/2 of tergal surface; bands flat and with no distinctive mid-dorsal peaks (Fig. 2a); abdominal bands wrapping around to the underside; bright yellow bands straddling the margin between tergites ST1+2, and T3 with yellow-gray color extending up to and beyond insertion point of median marginal bristles on ST1+2; T3 and T4 possessing 1 pair of medial discal bristles, insertion point of abdominal bristles punctuated by a black outline appearing as black spots.
Diagnosis
Small black and yellow fly, with 4 prominent black stripes on the thorax, these smudging together so that it appears as 2 large thoracic vittae. Males have a black scutellum, straight conical, and apically pointed abdomen, with 3 narrow gold bands interspersed with black wrapping the abdomen, terminating in a black tip. Female abdomen with a strong down-pointing curve abdominal, 3 grayish abdominal bands lacking mid-dorsal point.
Etymology
From the Latin
"uniformis"
, for not changing in form or character, in reference to the uniform nature of the pruinose bands on the abdomen.
Distribution
Costa Rica, ACG, Prov. Alajuela, rain forest, 109-135 m elevation.
Ecology
Reared from,
Elachistidae
,
Stenoma
Janzen44 and
Antaeotricha spurca
(2 records). One fly larva per caterpillar.
