Lichtwardtia minuscula Grichanov, 1998: 228 (nec Parent, 1934, misidentification).

TYPE MATERIAL. Holotype – ♂, Ghana: Banda-Nkwanta / VII–VIII 1965, leg.

Endrody-Y. [ HNHM]. Paratypes : 1♂, same label [ ZIN]; Ghana: Kumasi , 1 – 25.VI 1965, 2♂ ,

leg. Endrody-Y. [ HNHM].

DESCRIPTION. Male. Similar to Lichtwardtia minuscula in all respects except as noted.

Head: face distinctly narrowed at upper third; ratio of its minimal width to height 11/35;

antenna yellow; postpedicel darkened distally, as long as high; palpus yellow, with short brown setae.

Legs. Hind basitarsus with 1 reduced dorsal seta, at most 1/4 as long as basitarsus; fore tibia and tarsomere (from first to fifth) length ratio: 69/33/15/12/9/11.

Wing hyaline. Ratio of part of costa between R 2+3 and R 4+5 to this between R 4+5 and

M 1+2, 25/24; 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, 59/10/38/22/32;

Epandrium of moderate size, elongate, swollen basally, narrow distally, twice longer than high, with concave ventral margin (lateral view); hypandrium simple, basoventral, nearly as long as epandrium, without tooth; phallus thin and long, with small dorsal tooth positioned at middle of full length of epandrium; epandrial lobe undeveloped; 3 strong epandrial setae raising from dorsal side of epandrium in apical third; 2 epandrial setae positioned on apicoventral prominence; surstylus bilobate; ventral lobe short, digitiform, rounded at apex, with several short apical and subapical setae; dorsal lobe of surstylus somewhat longer and wider than ventral, broad at base, narrowed at apex, half as long as cercus, with 2 dorsal and 2 subapical short setae; postgonite very narrow, nearly as long as surstylus; cercus 1/3 as long as epandrium, twice longer than wide, elongate-oval, with acute distodorsal apex and long ventral cilia, of which apical cilia equal in length to medial width of cercus.

MEASUREMENTS (in mm). Body length 2.4; wing length 2.4; wing width 0.8; hypopygium length 0.6.

Female. Unknown.

DISTRIBUTION. Ghana.

ETYMOLOGY. The Latin name of the species belongs to the country of origin.

DIAGNOSIS. The new species is a sibling species with L. minuscula , differing reliably from the latter in male cercus apically narrow and pointed rather than broad and subquadrate;

hypandrium simple.

NOTES. Grichanov (1998) mentioned 3 females under the name L. minuscula from

Ghana, but from different localities. They are not included into the type series of L. ghanaensis , because two or more species of the genus can be collected from the same locality with their females being practically indistinguishable.
