DIAGNOSIS. Male. Head. Face grey-brown on upper part, whitish grey in middle, white pollinose on clypeus; face almost parallel-sided, narrowest at upper third; ratio of its minimal width to height 12/35; clypeus bulging, slightly convex ventrally, not reaching lower margin of eyes; lower postocular setae white; antenna mostly orange-yellow; postpedicel black in distal half, rounded, as long as high, slightly angular apicodorsally; length ratio of scape to pedicel to postpedicel to stylus (1st and 2nd segments), 14/12/16/11/40; palpus grey-yellow,

with black hairs and setae.

Legs bicolorate; fore coxa brown, mid coxa black with yellow apex, hind coxa brown with black spot in middle; femora mostly black with yellow apices, or all femora mostly yellow, broadly black dorsally; fore and mid tibiae dirty yellow; hind tibia black or dirty yellow with black apex; fore and mid tarsi black from tip of basitarsus; hind tarsus black;

femora without long hairs; fore tibia with 1 strong anterodorsal, 1 strong and 1 short posterodorsal setae, 1 posteroventral seta, about 2 times longer than diameter of tibia, 3 strong apical setae; mid tibia with 3 anterodorsal, 2 posterodorsal, 1 anteroventral and 5 apical setae; hind tibia simple, with 3 anterodorsal, 3 posterodorsal, 3-4 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: 88/40/19/ 16/12/15,

mid leg: 119/59/32/27/17/18, hind leg: 141/51/58/41/26/22.

Wing evenly greyish, inconspicuously darker along veins; costa simple; ratio of part of costa between R 2+3 and R 4+5 to this between R 4+5 and M 1+2, 33/26; 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, 73/11/48/35/44; lower calypter yellow, with black setae; halters grey-yellow.

Abdomen with 8th segment black; epandrium black, as long as 3rd-5th tergites combined, 2

times longer than high, swollen basally, narrowed distad, concave ventrally, projected and rounded distoventrally; hypandrium basoventral, reaching apex of epandrium, without teeth.

Phallus thin and long, simple; one epandrial seta far from base of hypandrium; 3 strong epandrial setae on distoventral projection; epandrial lobe absent; surstylus yellow, bilobate;

ventral lobe narrow, fingerlike, with 2 thick spines and 3 simple setae; dorsal lobe of surstylus broad, longer than ventral lobe, half as long as cercus, with apical projection and shallow distal emargination, with several subapical setulae; postgonite narrow, pointed at apex; cercus dirty yellow, black distally, elongate-ovate, 2 times longer than wide, serrate along distal margin, with straight cilia hooked at apex.

lateral view. 21 – L. aethiopica (Bezzi) ; 22 – L. dianaensis sp. n.; 23 – L. minuscula (Parent) ;

24 – L. musolini sp. n.; 25 – L. nikitai sp. n.; 26, 27 – L. oromiaensis sp. n.

MEASUREMENTS (in mm). Body length 2.9; antenna length 0.8; wing length 3.1; wing width 1.1; hypopygium length 1.2.

DISTRIBUTION. Type locality: Eritrea: "Dintorni di Adi Ugri" (= Mendefera , ~ 2000 m

a.s.l.). DR Congo (?), Eritrea. New for Ethiopia.

NOTES AND DIAGNOSIS. L. aethiopica is remarkable in having femora mostly or partly black. One of the two males examined is somewhat darker than another male, with mainly black femora. Specimens described by Bezzi (1906) have mainly yellow femora, being a little smaller (3 vs. 3.5-4 mm). The other species of the genus have entirely yellow femora,

though I saw a L. angularis phenotype with partly black femora, differing from L. aethiopica in distinctly maculated wing at M 2 and dm-m veins; postpedicel usually 1.5-2 times longer than high, with drawn-out or acute apex; and in morphology of hypopygium.
