Differential diagnosis. This new Camptomyia differs from its congeners in the structure of the gonostylus, which has a bundle of dense, jumbled spines subapically ( Fig. 20 , arrow 1), rather than several spines arranged in a line, forming a pectinate tooth at the apex. The phallapodeme length is 2 × that of the parameres and is unusually thick ( Fig. 18 , arrow 2), apart from constrictions both subapically and subbasally. The parameres, in turn, are peculiar in having their apical portions, i. e., ca one-third of their entire length, turned backward ( Fig. 18 , arrow 3). The basal portions of the parameres are interconnected.

Male description. Body length 2.2 mm. Head. Eye bridge 9 ommatidia long at vertex. Antenna shorter than body, with 20 flagellomeres, all with circumfila; apical flagellomere simple. Neck and node of fourth flagellomere of equal length ( Fig. 19 ). Palpus 4-segmented, shorter than head height. Thorax. Pronotum glabrous; 5 anepisternal setae; 6 anepimeral setae. Wing. As long as body, length/width ratio 2.6. 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 1.1 × 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 narrow, sclerotized ridge inside along median, setae arranged in two lateral clusters, anterior margin weakly contoured ( Fig. 17 ). Gonocoxal synsclerite strongly narrowed anteriorly; anterior margin bluntly pointed; ventral emargination broadly U-shaped basally, with sclerotized margin devoid of vestiture; ventrolateral setae markedly larger than those around the emargination; dorsal apodemes thin, shorter than the distance separating them ( Fig. 16 ). Gonostylus 3 × as long as high, almost straight, slightly convex posteriorly, slightly tapered towards apex; basolateral apophysis small ( Fig. 20 ). Parameral apodemes moderate size ( Fig. 18 ).

Female unknown.

Etymology. The specific epithet kwazulunatalensis is an adjective derived from the name KwaZulu-Natal, type locality of the species.

Type material examined. 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 (NMSADIP 212003).
