Diagnosis
♂. Ground colour of face and frons orange, of the occiput and the area of ocellarium black. Hind margin of eyes with a narrow stripe of whitish scales; the edge of neck cavity with dense whitish hairs. Frons with a cross-furrow at the middle, and with short, black hairs, but on the lower one-fourth with yellowish adpressed scales. Antennae brownish. Style long, about as long as the first antenna1 segment, and slightly shorter than the third segment. Hairs on first segment dense, black. The ratio between the eyes and vertex viewed from above 16 : 4 : 16. Hairs on face very short, sparse, black towards the centre, yellowish at sides. Proboscis black; palpi yellowish, extremely thin. Occiput, in profile at the bisection line of eyes, about as broad as half the horizontal diameter of eye.
Mesonotum black, covered with short, dense, yellowish, adpressed hairs, and therefore presenting a grey nuance. Scutellum brownish, with similar hairs. "Collar" at anterior margin with very long, dense, erect, yellow hairs. Humeral calli with a tuft of black semi-bristles, and similar semi-bristles and 2 long and strong bristles in the notopleural area. Postalar calli with 5-6 long, black bristles. Scutellum with about 8 pairs of short, black incurved bristles; the apicals decussate. Sides of thorax with very dense, silky hairs, the hairs longer and almost yellow in the upper part, and shorter, almost white in the lower part. Legs black, with black scales and spicules. Halteres brownish; in front of and above the halteres, there are extremely dense, erect, whitish or slightly yellowish hairs.
Wings very long, comparatively narrow, appearing humped in the area of apex of R1. First posterior cell at apex almost closed; 4 submarginal cells. Vein r-m distinctly before the middle of discal cell. Cell M1 almost straight, M2 slightly S-shaped. Most cells, especially the marginal, with strongly corrugated membrane. The extreme base of wing, including the triangular cell, and the area along the anterior margin, rather bright yellow; most of wing regularly darkened, the colour less dense only in the apical area; nowhere very strong, giving an appearance of dark clouding rather than distinct blackness.
Abdomen egg-shaped, distinctly broader than thorax; ground colour of abdomen black. The dorsum has very typical markings: first tergite very short and not easily discernible; second tergite broad, with 2 very contrasting fasciae, the anterior one bearing almost white or slightly yellowish scales, the posterior one with deep black scales, and the separating line curved, not straight; third and fourth tergites deep black, but the lateral anterior corners of the third tergite may sometimes have whitish or yellowish scales; tergites 5-7 mostly snow-white, with black hairs laterally, and a rather broad, black, median separating stripe, i.e. having 3 pairs of snow-white fasciae or spots. Venter, 3 basal sternites snow-white, fourth and fifth deep black, and sixth and seventh with snow-white scales, but without the hairs which are present on the first 3 sternites. Genitalia black, in oblique position.
♀. Very similar to the male, but with slightly broader vertex, and distinguished at once by the presence of only a 1-segmented whitish preapical fascia on the underside of abdomen; in the male there are 2 fasciae.
