one strong vertical, one short postvertical, a pair of strong ocellar setae present; lower postocular setae white; ventral postcranium with 2 long white setae and several light cilia; eyes with short hairs; face glabrous; face almost parallel-sided; clypeus slightly bulging, not reaching lower margin of eyes; ratio of its minimal width to height 20/42; antenna orange-yellow; postpedicel black in distal half, subtriangular, as long as high, rounded apicodorsally, with short hairs; arista-like stylus middorsal, black, sparsely pubescent, with hairs 2-4 times longer than basal diameter of stylus; length ratio of scape to pedicel to postpedicel to stylus, 15/10/17/

10/51; palpus dirty yellow, with short black hairs and 1 fine black seta; proboscis brown.

Thorax. Mesonotum metallic black-violet, weakly pollinose; pleura blueish-black, grey pollinose; 5 strong dorsocentral setae with several microscopic hairs in front of the 1st pair, 2

rows of acrostichals; proepisternum with 1 strong black seta above fore coxa and several short hairs; scutellum with 2 strong setae and 2 short lateral hairs.

Legs mostly yellow; fore coxa yellow, mid coxa black with yellow apex, hind coxa yellow with black spot; hind tibia blackish at apex; fore and mid tarsi black from tip of basitarsus;

hind tarsus black; femora without long hairs; fore coxa with black hairs and several long apical setae; fore tibia with 2-3 anterodorsal, 2-3 posterodorsal, 2 posterior seta, of which lower seta nearlly 3 times as long as diameter of tibia, 2 strong apical setae; fore tarsus simple,

fore basitarsus with short basoventral seta; mid femur with 1 subapical anterior and 1 subapical posteroventral setae; mid tibia with 3 anterodorsal, 2 posterodorsal, 1 anteroventral and 5

apical setae; hind femur with one anterodorsal prepapical seta; hind tibia simple, with 4 anterodorsal, 4 posterodorsal, 1 strong and 2-3 short ventral, 3 apical setae; hind basitarsus with 1

basoventral, 1 apical short setae; 1 strong dorsal seta, half as long as basitarsus. Tibia and tarsomere (from first to fifth) length ratio: fore leg: 99/48/21/16/14/17, mid leg: 141/64/35/

32/21/21, hind leg: 168/57/66/48/33/25.

Wing evenly greyish, somewhat darker on crossveins; costa simple; R 1 reaching to first third of wing; R 2+3 and R 4+5 straight, slightly divergent at apex; ratio of part of costa between

R 2+3 and R 4+5 to this between R 4+5 and M 1+2, 31/28; M 1+2 broken in middle of distal part,

joining costal vein just before wing tip; R 4+5 and distal part of M 1 parallel; crossveins m-m

and dm-m straight, almost perpendicular to corresponding longitudinal veins; ratio of distal part of M 1 to m-m to distal part of M 1+2 to dm-m to distal part of M 4, 85/16/54/36/36; anal vein distinct, almost reaching to wing margin; anal lobe well developed; anal angle obtuse;

lower calypter yellow, with black setae; halters yellow.

Abdomen metallic bronze-black, whitish pollinose laterally, with black hairs and marginal setae; 8th segment black, with sparse black hairs; epandrium black, about as long as 3rd-

6th tergites combined, 2 times longer than high, swollen basally, narrowed distad, concave ventrally, rounded distally; hypandrium basoventral, nearly as long as epandrium, with wormlike apical process behind small dorsal tooth; phallus thin and long, with small dorsal tooth far from apex; one small epandrial seta at base of hypandrium; 3 strong epandrial setae distoventrally; epandrial lobe undeveloped; surstylus yellow, bilobate; ventral lobe broad, as wide as long, with 1 long and 3 short setae; dorsal lobe of surstylus broad, longer than ventral, 2/3

as long as cercus, with apicoventral and apicodorsal projections and distal emargination, 2

long setae and few short setulae; postgonite broad, spoonlike, as long as surstylus. Cercus yellow, black along distal margin, semi-circular, higher than long, with straight and curved marginal setae not longer than diameter of cercus.

MEASUREMENTS (in mm). Body length 3.3; antenna length 0.8; wing length 3.4; wing width 1.2; hypopygium length 1.0.

Female. Unknown.

DISTRIBUTION. Ethiopia.

ETYMOLOGY. The species is named after the Russian entomologist, Dr. Dmitrii Musolin

(St. Petersburg, Russia).

DIAGNOSIS. The new species is close to L. tikhonovi Grichanov , differing from the latter in hypandrium bearing worm-like apical process behind small dorsal tooth; ventral lobe of surstylus broad. Hypandrium has no tooth, and ventral lobe of surstylus is narrow in L.

tikhonovi. L. musolini sp. n. is distinguished by wing evenly greyish, slightly infumated at crossveins; costa simple; postpedicel as long as high; hind tibia yellow, blackish at apex; fore tibia with one strong and long posterior seta; hind basitarsus with 1 strong dorsal seta; cercus rounded.
