Description (holotype, female). Length, 8 mm. Eyes bare. Front a little taller than broad, slightly convergent above, index 1 :1.3 (based on median height), buff-gray pollinose in a band across the vertex, the remainder filled with the blackish, confluent frontal spots and the deep brown, protuberant, broadly heart-shaped, bare basal callosity; the small, upper black spot is almost surrounded by the more brownish, upper margin of the confluent paired spots; a peculiar, narrow, contrasting yellow-red, shiny band margins the callosity below, surrounding the antennal fossae. Face gray pollinose with sparse white pile, no prominent spots. Antennae very long, equal to length of notum minus scutellum, cylindrical and slender, scape red with no constrictions, equal to the plate in length, the latter subcylindrical and but little thickened basally, red on the extreme base grading to black distad of the apical two thirds. Palpi robust, dull brownish, with sparse black hairs but little shorter than the stylets, proboscis brownish black. Notum, including scutellum and antealar tubercles, chocolate brown, unlined except for an abbreviated narrow yellow pollinose line anteriorly; around the pre- scutellum an irregular but bilaterally symmetrical, yellow pollinose figure consisting of an inverted half moon on the disc of the scutellum, above which are two tilted triangles with a short, diagonal lobe extending outwardly on the hind margin of the notum on each side. Pronotal lobes with brownish-yellow tinge. Pleura dull brown with yellow hairs. Fore coxae and tibiae sharply divided in color in the middle, bright yellow basally and chocolate brown distally, hairs concolorous; two hind pairs of coxae and all femora unicolorous brown. Two hind pairs of tibiae brown with two yellow bands, the basal one broadest, and a similar one on first respective tarsal (metatarsal) segments. Fore tarsi black. Wings brown, the rosettes and spots reduced; costal cell and R basad of the stigma entirely yellow, the first basal cell predominantly yellow in the outer half, the apical cross band double but both branches discontinuous behind their junction at tip of vein R2+3 , the outer one represented by a large spot just below the apex in cell R 4 ; a round spot without dark center at tip of stigma, and all marginal cells with yellow triangles at the outer corners. Spur-veins present. Subepaulets small, scale-like, with only two to three bristles. Halteres orange yellow. Abdomen chocolate brown, no pattern except for narrow yellow incisures above. First tergite laterally without gray expansion of incisure.
