Diagnosis. Eyes uniformly pilose (typical of subgenus Pandasyopthalmus  ), covered with dense, white pile as long as pedicel, and narrowly separated by a length of about two ommatidia ( Fig. 7AView FIGURE 7). Face with distinct tubercle. Spurious vein extending beyond the meeting point of vein M with the discal cross-vein ( Fig. 2AView FIGURE 2). Medial longitu- dinal protuberance at the boundary between sterna 2 and 3 present ( Figs 2View FIGURE 2 C–D: pr); posterior margin of sternum 4 medially protruded, with two tufts of black pile medially ( Figs 2View FIGURE 2 C–D: t). Surstylus squared with apical protuberance and inner spine (marked with arrow on Fig. 3BView FIGURE 3); hypandrium as in Figs 3View FIGURE 3 C–D; paramere broad basally and tapering towards the rounded apex, with a lateral spine (marked with arrow on Figs 3View FIGURE 3 C–D).

Based on its external morphological characters, Paragus longipilus  sp. nov. belongs to the subgenus Pandasyopthalmus  . Paragus longipilus  sp. nov. differs from other described species of the genus by having much lon- ger and denser body pile. Additionally, the medial longitudinal protuberance at the boundary between sterna 2 and 3 is present ( Figs 2View FIGURE 2 C–D: pr), as well as the posterior margin of sternum 4 medially protruded with two tufts of black pile medially ( Figs 2View FIGURE 2 C–D: t). The aedeagus complex ( Figs 4View FIGURE 4 A–C) is similar to that of the species Paragus jozanus Matsumura in Matsumura & Adachi 1916  (see Fig. 66 in Vujić et al. 2008).

Description. MALE. Body length 5.1 mm, wing length 3.7 mm. Head ( Figs 2View FIGURE 2 A–B, 7A). Eyes with dense, white, uniformly distributed pile, as long as pedicel, and narrowly separated by a length of about two ommatidia; antenna dark brown to blackish; basoflagellomere 1.75 times longer than wide, with rounded apex; arista dark brown; face yellow except black medial vitta extending from the oral margin to the tubercle, densely covered with long white pile and with distinct tubercle; frontal triangle yellow with yellow pile, except for a few black pile around the lunule; vertical triangle black, with golden sheen, covered with black pile anterior to anterior ocellus and yellow pile on the area posterior to the ocellar triangle; ocellar triangle equilateral, with black pile; occiput narrow, whitish pollinose, covered with dense yellow pile. Thorax ( Figs 2View FIGURE 2 A–B). Scutum black, with golden sheen, covered with yellow pile; pleuron black, whitish pollinose, except ventral part of katepisternum; anepisternum, anepimeron and dorsal part of katepisternum with patch of long white pile; calypter whitish; pedicel of halter dark brown, capitu- lum yellow; wing hyaline, covered with microtrichia except bare costal cell (C), basal part of subcostal cell (SC), first basal cell (R) and second basal cell (BM); spurious vein extending beyond the meeting point of vein M with discal cross-vein; stigma brownish-yellow; coxae and trochanters black; pro- and mesofemora black on basal 1/2, metafemur black on basal 3/4; tibiae and tarsi yellow; metatibia yellow with slightly darker ring in the submedial part ( Fig. 2AView FIGURE 2); scutellum black with golden sheen, covered with yellow pile, as long as the length of scutellum. Abdomen ( Fig. 2View FIGURE 2). Terga black with golden sheen, with white erected pile on anterior half and black adpressed pile on posterior half; tergum 2 with long white pile on lateral margins ( Fig. 2BView FIGURE 2); sterna 1 and 2 with long white pile, sterna 3–5 with short white pile, sterna 6–8 with black pile; boundary between sterna 2 and 3 with medial longitu- dinal protuberance ( Figs 2View FIGURE 2 C–D: pr); posterior margin of sternum 4 medially protruded, with two tufts of black pile medially ( Figs 2View FIGURE 2 C–D: t). Terminalia ( Figs 3View FIGURE 3, 4View FIGURE 4). Surstylus squared with apical protuberance and inner spine ( Figs 3View FIGURE 3 A–B: s); hypandrium as in Figs 3View FIGURE 3 C−D, paramere broad at the base and tapering to the rounded apex, with lateral spine (marked with arrow on Figs 3View FIGURE 3 C–D); posterior rim of hypandrium differentiated into a wide lingula ( Fig. 3CView FIGURE 3: l); ejaculatory apodeme on Fig. 3EView FIGURE 3.

FEMALE. Unknown.

Etymology. The word ʻ longipilus  ʼ derives from the Latin adjective ʻ longus ʼ meaning long and ʻ pilus ʼ as nomi- native of the noun pile, referring to the long pile uniformly distributed on the eyes and other body parts.

Distribution. Paragus longipilus  sp. nov. is distributed in southern parts of the Republic of South Africa, in the

Western and Eastern Cape Provinces ( Fig. 1View FIGURE 1).
