Figs 21–24

Differential diagnosis. An unusual species of Camptomyia, distinguished by the construction of the parameres. The dorsolateral portions form a pair of ovoid lobes the surfaces of which are clothed in thick microtrichia (Fig. 23, arrow 1), while the ventral portions, which are much less obvious, form a subrectangular, virtually transparent shield (Fig. 21, arrow 2). Parameres similar to those of C. mostovskii sp. nov. were described for Lobopedosis maritima Fedotova & Sidorenko, 2005, the type species of the monotypic genus Lobopedosis Fedotova & Sidorenko from Far East Russia (Fedotova & Sidorenko 2005, fig. 123). While Lobopedosis is currently recognized as a valid genus of Asynaptini (Gagné & Jaschhof 2021), observations here suggest L. maritima to be another unusual species of Camptomyia . This assumption should be considered carefully in future revisions of Palearctic Asynaptini .

Male description. Body length 1.7 mm. Head. Eye bridge 7 ommatidia long at vertex. Antenna longer than body, with 17 flagellomeres, all with circumfila; apical flagellomere simple. Neck of fourth flagellomere 1.3 × as long as node (Fig. 24). Palpus 4-segmented, shorter than head height. Thorax. With 2 pronotal setae; 10 anepisternal setae; 8 anepimeral setae. Wing. Longer than body, length/width ratio 2.7. A short, faint portion of vein M 1+2 present at wing margin. Both vein M 4 and apical portion of vein CuA weak, although forming a fork and extending to wing margin. Legs. Foreleg with femur 1.2 × as long as tibia, T 2 not retained; midleg with femur 1.3 × as long as tibia, tibia 0.7 × as long as T 2. Claws moderately bent, 1 large basal tooth. Empodia vestigial. Terminalia. Ninth tergite with deeply incised posterior margin, anterior margin weakly contoured (Fig. 22). Gonocoxal synsclerite strongly narrowed anteriorly; anterior margin narrowly rounded, weakly contoured; ventral emargination broadly U-shaped, basal margin weakly contoured; dorsal apodemes thin, almost as long as the distance separating them (Fig. 21). Gonostylus twice as long as high, almost straight, slightly convex posteriorly, slightly tapered towards apex; basolateral apophysis small; apex with small pectinate tooth (Fig. 21). Phallapodeme consisting of a rodshaped portion basally and an elongate-subtriangular extension apically, both approximately same length (Fig. 23). Parameral apodemes moderate size (Fig. 23).

Female unknown.

Etymology. The specific epithet renders honor to the dipterist Mike B. Mostovski, who as the former Chief Curator contributed significantly to the development of the Diptera collection of the KwaZulu-Natal Museum, Pietermaritzburg, South Africa. All the specimens studied here were collected by him.

Type material. Holotype. Male, South Africa, KwaZulu-Natal, Karkloof Nature Reserve (29°19.1′S: 30°15.5′E), 1325 m elevation, mistbelt forest, 28.ix.–24.xi.2005, Malaise trap, M. Mostovski (NMSA-DIP 212004).
