Description

Male: body length 4.5-7.0 mm

Head: Frontal vitta black pruinose, at narrowest point as wide as anterior ocellus. Fronto-orbital plate silvery pruinose, at uppermost fr 0.9x width of anterior ocellus. Thirteen long fr, slightly longer than flagellum. Upper orb present. Eye bare, antero-internal facets larger than remaining; pocl sirregular in length. Face and parafacial covered with thick shining silvery grey pruinescence. Parafacial at base of flagellum 0.6x width of same and bare. Facial carina dark grey. Gena dark grey to black. Scape and pedicel black; flagellum 2x as long as broad and covered with thick grey pruinescence. Arista black and short pubescent. Palpus black, straight, the apex as wide as base. Lower oral margin light grey, slightly concave and groove less.

Thorax: Scutum brown greyish, dark brown vittae visible in full length of acr and dc lines; pleura grey; scutellum light grey at apex; 3+4 acr, 1 strong prescutellar acrs; 2+3 dc; pprn with few short setulae; Two to four short pral near spal: prealar area with few setulae; 2 prepm, lacking surrounding setulae.

Legs: Dark brown to black, light brown to yellow at articulations. In some specimens tibial base is yellow. F1 normal (length/width = 6), with 1 row of pd; 2 rows of p; 1 long basal and 1 row of pv in apical 3/4. T 1 with 1 subapical pd; 1 apical v and pv; 1 row of setulose ad and 1 submedian and 1 apical ad. Fore tarsomere 1 0,5x length of tibia; tarsomeres 4 and 5 short, as wide as long. F2 with 1 complete row of ad; 2 rows of very short a; 1 row of long and fine av at base, shorter and stouter towards apex; 1 row of hair-like pv, as long as femoral width; 1 row of fine p at base and 5 to 6 longer, stouter and ventral p at base. T 2 constricted at base, lacking subbasal protuberance; ventral pubescence short, 0.25x width of tibia; with 1 submedial a; 1 subapical ad; 1 submedial and 1 apical pd; 1 apical pv; 1 apical p. C3 with 3 short and hair-like p at apex of posterior surface. F3 normal (length/ width = 6.25), lacking posteroventral protuberance; with 1 row of ad, longer, stouter and dorsally directed towards apex; 1 row of av interrupted at preapex, and 2 apical av; posterior surface covered with hair-like setulae ( Fig. 5A ). T 3 with 1 submedial and 1 subapical d; 10 medial ad, and 1 stouter submedial and apical ad; 2 to 3 medial av and 1 apical av; apex of ventral and posteroventral surfaces with a short ctenidium.

Wing: Clear; both calypteres rounded, white, yellowish in outer margin. Knob of halter yellowish-white, light brown at base.

Abdomen: Elongated, the width of tergites approximately uniform. Brownish-grey, and yellow at apex of tergite 1 and lateral margins of tergites 2 and 3 and basal half of tergite 4.

Postabdomen: Posterior margin of sternite 5 straight, with setae forming a central longitudinal line ( Fig. 5B ). Hypandrium broad, strongly sclerotized, hypandrial arms directed inwards; postgonite hornshaped, strongly sclerotized surrounding the membranous aedeagus ( Fig. 5C ). Cercal plate small and fused; bacilliform process absent; surstyli near outer margin of epandrium and formed by a flattened, parallel sided, principal process and a ventral, lateral, smaller and depressed process, that bears a group of setulae at apex, each surstylus is directly and broadly connected to the hypandrium ( Fig. 5D ).

Female: body length 4.8-5.2 mm. Differs from male as follows:

Head: Ocellar triangle short, extending up to the fourth fr. Frons and vitta broad, the distance between eye margins is 1/3 of head width. Parafacial with 1 row of short setulae reaching base of flagellum. Seven to eight fr as long as flagellomere and 1 row of orbital setulae.

Thorax: Light grey with thinner brown vittae along acr, dc and ia lines; 3+4-5 acr; 2 short and thin pral near spal, lacking setulae in prealar area.

Legs: Dark brown, yellow in articulations, trochanter yellow and tibiae reddish. F2 with very short and thin row of av in basal fourth; row of pv very short with a long setae at base and setulose towards apex. T 2 narrow at base, broader at apex; ventral pubescence absent.

Abdomen: Heart-shaped, tergite 4 approximately half as wide as tergite 2. Tergite 1 dark grey brownish to grey purplish, tergite 2 completely yellow, tergite 3 yellow at base and tergites 4 and 5 brown-purplish.

Postabdomen: Cerci normal, short; anal plate slightly broader than long, uniformly covered with setae; sternite 8 reduced to an anterior pair of plates covered with setulae and two posterior bare plates slightly larger than anterior; postabdominal spiracles 7 and 8 on tergite 6 ( Fig. 5E ). Two rounded spherical soft surfaced spermathecae, with unsclerotized ducts.

Distribution: Cosmopolitan.
