Diagnosis. Among the cluster of species with an anepisternal tuft of hairs and an S-shaped dorsal antennal process, this new species is similar to S. pappi, n. sp. by the black anterior thoracic color, but it can be distinguished from it by the yellow mid femur and tibia (these segments black in S. pappi) and the brown propleuron (yellowish brown in S. punctata).

Hennig’s (1940) original description is extremely vague. A redescription below is based on the only two known verified specimens of this species (the holotype male and paratype female) and follows the format of other descriptions in this paper to allow for easy comparison of characters and character states.

Redescription. Lengths. Ƌ: [holotype missing abdomen; see remarks below]; wing, 3.0 mm. Male. Head (Fig. 3): globular; frons shining black, thin yellow margin at ptilinal suture; face yellow; gena black, gray pollinose, row of short black hairs ventrally; occiput black; clypeus thin, dark brown; palpus (Fig. 16) subtriangular with flared, rounded apex, yellowish with stiff black hairs ventroapically, admixed with short white hairs dorsoapically; proboscis black.

Antenna (Fig. 34) scape and pedicel yellowish brown; flagellomere subrhomboid, dorsal margin concave, rounded apically, longer than wide, lateral surface yellow basomedially, brown apically, mesal surface clothed with white hairs, with long, slender, dark brown S-shaped dorsal process densely clothed with white hairs, 2.5 times length of flagellomere; arista three-fourths length of dorsal process, styliform, bare.

Thorax (Fig. 42): shining; mesonotum and scutellum shining black, sparsely clothed with short hair-like setulae; propleuron brown, remaining pleura black; anepisternum with tuft of silvery white hairs medially, minute white hairs posterodorsally at prealar suture; katepisternum with white hairs ventrally near mid coxa.

Wing (Fig. 49): hyaline; vein R2+3 nearly straight, ending in costa well beyond level of crossvein dm-cu; crossvein r-m just before middle of cell dm; veins R4+5 and M1+2 parallel distally; crossvein dm-cu sloping to CuA1; last section of CuA1 to wing margin slightly shorter than dm-cu; halter white.

WIP (Fig. 48): generally bluish to lavender and purple; radial field with dark blue in distal half, some brassy green color basally; medial field with turquoise blue at apex and along R4+5; anal lobe with thin band of brassy golden color subbasally, then blue, indigo, to purple in succession distally.

Legs: legs yellow with mid coxa brown, mid femur black, mid tibia black, yellow at apex [right mid leg broken off and glued to label]; hind femur black, yellow at extreme base, hind tibia black, yellow at extreme apex [right hind leg broken off and missing]; tarsi white; fore coxa with 3 long black hairs; fore femur (Fig. 74) dorsally with 5 short black thorn-like spicules, scattered stiff brownish hairs laterally and ventrally.

Abdomen: [broken off and missing].

Male genitalia. Not available for study. Hennig’s (1940: fig. 15) illustration is rather simplistic and gives only the general appearance of the male genitalia of this species, which is actually sufficient for any species of the S. punctata subgroup since there are very few notable differences in the male genitalia among its species.

Female (head and fore legs of paratype female broken off and missing): As in male except for lack of leg modifications; abdomen black, tapering to tubular ovipositor.
