Differential diagnosis.
Asynapta mpofana
sp. nov.
is distinguished by the following combination of male terminalia characters. The gonostylar apex bears a bundle of short, dense spines apically (
Fig. 6
, arrow 1); the posterior margin of the ninth tergite has a reinforced, rectangular notch medially (
Fig. 7
, arrow 2); and the tegmen is peculiar in having a dual-chamber structure (
Fig. 8
, arrow 3), the large, seemingly 2-pointed apex (
Fig. 8
, arrow 4) and a bilobed, roughly V-shaped outgrowth ventrally of the phallapodeme (
Fig. 8
, arrow 5). The basic shape of the tegmen of the Somalian species
A. africana
is similar, although there are obvious differences in the details (
Mamaev & Zaitzev 1997
, fig. 3c).

Male description.
Body length
1.9 mm
.
Head.
Eye bridge 6 ommatidia long at vertex. Antenna as long as body, with 21 flagellomeres, all with circumfila; apical flagellomere simple. Neck and node of fourth flagellomere equally long (
Fig. 10
). Labellum extremely small, glabrous. Palpus 1-segmented, with sparse setae.
Thorax.
Pronotum bare; 8 anepisternal setae; 6 anepimeral setae.
Wing
(
Fig. 9
). Slightly longer than body, length/width ratio 2.9. Basal longitudinal vein markedly bent. Vein

absent. Vein
CuA
fading before wing margin.
Legs.
Foreleg with femur and tibia of equal length, tibia 0.9 × as long as T
2
. Claws moderately bent, 1 large basal tooth. Empodia vestigial.
Terminalia.
Ninth tergite subtrapezoid, evenly setose (
Fig. 7
). Gonocoxal synsclerite strongly narrowed anteriorly, anterior edge narrowly rounded, weakly contoured; ventral emargination large, U-shaped, lateral margins moderately sclerotized, basal margin reinforced by sclerotization laterally, slightly convex, with indistinct, broad margin largely devoid of vestiture; dorsal apodemes long, their lengths equal to distance separating them (
Fig. 6
). Gonostylus 2.5 × as long as high, slightly bent, moderately convex posteriorly, tapered towards apex; basolateral apophysis large; setae near apex clearly smaller than those elsewhere (
Fig. 6
). Phallapodeme simply rod-shaped, clearly shorter than tegmen, well sclerotized, mouths of accessory gland ducts indistinct (
Fig. 8
). Parameral apodemes normal size (
Fig. 8
).
Female unknown.
Etymology.
The specific epithet
mpofana
, a noun in apposition, refers to Mpofana, one of the local municipalities in which Karkloof Nature Reserve is located and
type
locality of the species.
