Stratiomys approximata Brunetti, 1923 View in CoL
Stratiomyia approximata Brunetti, 1923: 115 .
Diagnosis
Stratiomys approximata is diagnosed by having eye distinctly hairy, scutellar spines straight or slightly incurved, wing slightly brownish towards middle region, yellow angled spots at edges of abdomen on tergite II, III and IV not joining at middle, mostly black tibiae; black femur, and mostly yellow tarsi with apical 2 segments blackish brown. The species is somewhat similar to S. barca , which can be separated by having yellow spots on tergites joining at middle forming a narrow continuous band, and femur brown and tarsi black.

Redescription
MEASUREMENTS. Male ( Fig. 2 View Fig ): body length, 11.7–12.2 mm; wing length, 9.8–9.9 mm; female ( Fig. 3 View Fig ): body length, 11.9–12.5 mm; wing length, 9.6–10.6 mm.
HEAD. Elliptical in anterior view, eyes distinctly hairy, antenna with 5 flagellomeres, black except for brownish pedicel and yellowish-brown base of 1 st flagellomere, flagellum longer than scape and pedicel combined; area around antenna black ( Fig. 2D–E View Fig ); face black with two small yellow spots in male, near eye margin below base of antenna ( Fig. 2C–E View Fig ), much wider spots in female starting above antennal base and extending almost to lower margin of eye, leaving black pattern extending along frontal depression and continuing as broad medial stripe on face ( Fig. 3D–G View Fig ).
THORAX. Black with yellowish white dense and long pilosity ( Fig. 2H–I View Fig ); scutellum mostly black except for narrow yellow band along apical margin with two prominent spines ( Fig. 2J View Fig ); wing generally hyaline but slightly brownish towards middle region with brownish veins; veins M 1, M 2, M 3 and M 4 curved, ending before wing margin; vein r-m <M 2 ( Figs 2K View Fig , 3K View Fig ); legs mostly black with tarsus, base and apex of tibia yellow.
ABDOMEN. Black, broader than thorax with whitish yellow angled spots at edges of abdomen on tergite II, III and IV; spots on 2 nd tergite wider ( Fig. 2L–M View Fig ); abdomen banded ventrally, sternites black with yellow margins, joined in middle forming a continuous yellow band from 2 nd –4 th sternite.
MALE TERMINALIA ( Fig. 2N–P View Fig ). Epandrium convex and semioval with emarginate anterior margin, transverse posteriorly, with short fine setae, denser towards lower and lateral margins and sparsely distributed towards centre; proctiger subtriangular with suboval cercus having posterior margin obliquely transverse, margins with large and small setae ( Fig. 2N View Fig ); in lateral view, cercus covering terminalia up to base of distal portion where aedeagal lobes are joined; synsternite triangular, with short and thick setae on middle portion and longer setae on lower middle and lateral margins; distal margin of synsternite arcuate medially, laterally produced into oval processes with round margin; gonostylus longer than wide, placed on distal third of synsternite, ending in short pointed edge; gonocoxal apodemes reaching up to anterior margin of genital capsule ( Fig. 2O View Fig ); phallus smooth, distinctly longer than genital capsule, tripartite distally, medial lobe distinctly shorter and wider than outwardly divergent lateral lobes ( Fig. 2P View Fig ); medial lobe arcuate terminally, lateral lobes pointed.
FEMALE TERMINALIA ( Fig. 3N–O View Fig ). Tergite 9 nearly rectangular, anterior margin sub-medially emarginate, creating nearly triangular process medially; tergite 10 strongly triangular, distal apex rounded; cerci ovate, narrow at base and wider towards apex ( Fig. 3N View Fig ); genital fork wide, anterior third more or less semicircular, narrower than posterior two-thirds; posterolateral process wider basally, narrower and strongly convergent towards apex; posterior bridge with shorter projections ( Fig. 3O View Fig ).
