brown; postpedicel black in distal half, subtriangular, inconspicuously longer than high, rightangular apicodorsally, with short hairs; arista-like stylus middorsal, yellow-brown, sparsely pubescent, with hairs 2 times longer than basal diameter of stylus; length ratio of scape to pedicel to postpedicel to stylus, 12/11/19/6/41; palpus and proboscis brownish, with short black hairs; palpus with 1 black short seta.

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

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

Legs mostly dirty yellow; fore coxa brownish yellow, mid and hind coxae black with orange apex; fore and mid tarsi black from tip of basitarsus; hind tibia at apex and hind tarsus black; hind femora without long hairs; fore coxa with black hairs and several long apical setae; fore tibia with 2 strong anв 2 fine dorsal, 2 posterior seta, about as long as diameter of tibia, 3-4 apical setae; fore tarsus simple, fore basitarsus with short basoventral seta; mid femur with 1 subapical anterior seta; 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, 3-4 posterodorsal, 1 row of short ventral, 2-3 apical setae;

hind basitarsus with 1 basoventral, 1 apical short setae, 1 strong dorsal seta, nearly half as long as basitarsus. Tibia and tarsomere (from first to fifth) length ratio: fore leg: 95/39/19/

17/12/15, mid leg: 129/58/35/27/20/14, hind leg: 150/56/61/40/30/23.

Wing evenly brownish, 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, 38/30; 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, 81/14/52/25/28; anal vein distinct, almost reaching to wing margin; anal lobe well developed; anal angle obtuse;

lower calypter orange, with black setae; halters yellow.

Abdomen metallic black, grey pollinose, with black hairs and marginal setae; 8th segment black, with sparse black hairs; epandrium black, enlarged, nearly as long as 3rd-6th tergites combined, 2 times longer than high, swollen basally, narrowed distad, rounded distally,

asymmetrically projected ventrally, with semi-circular right lobe and subtriangular left lobe;

hypandrium basoventral, as long as epandrium, broad, with large dorsal tooth at base; phallus swollen and serrate dorsally at base of hypandrium, pointed at apex, with dorsal tooth far before apex; one small epandrial seta at base of hypandrium; 3 strong pedunculate epandrial setae distodorsally; epandrial lobe undeveloped; surstylus yellow, bilobate; ventral lobe broad,

longer than wide, with 2 thick spines and 3 simple setae; dorsal lobe of surstylus broad, longer than ventral, 2/3 as long as cercus, with few short setae; postgonite short, narrow, shorter than surstylus; cercus dirty yellow, black in distal half, rounded, slightly longer than wide, with angular apex distodorsally, with short curved setae distally, half as long as width of cercus.

MEASUREMENTS (in mm). Body length 3.3; antenna length 0.8; wing length 3.3; wing width 1.0; hypopygium length 1.3.

Female unknown.

DISTRIBUTION. Ethiopia.

ETYMOLOGY. The name of the new species belongs to the Oromia Province of Ethiopia.

DIAGNOSIS. The new species is remarkable in having mostly matt brown-black face.

Only L. nigrifacies Grichanov was previously known with mostly mat-black male face,

differing from L. oromiaensis sp. n. in postocular setae entirely black, all tibiae partly blackish on dorsal side, and in characters of hypopygium ( Fig. 12 ).
