Type material. HOLOTYPE. Republic of South Africa, ♂, pinned. Original label: “ RSA, Western Cape Province, Ceres District, Gydo Pass, 33°13’22.1988”S, 19°19’11.1606”E, 1071 m a.s.l., 08.xii.2016, leg. Vujić (ZA3_197, FSUNS)”. PARATYPE: Republic of South Africa: Eastern Cape Province, Naude’s Neck Pass, ♂, 30°44’54.2436”S, 28°13’1.308”E, 1899 m a.s.l., 30.xi.2017, leg. Vujić, Radenković, Veličković (ZA4_131, FSUNS).
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. 7A). Face with distinct tubercle. Spurious vein extending beyond the meeting point of vein M with the discal cross-vein (Fig. 2A). Medial longitu- dinal protuberance at the boundary between sterna 2 and 3 present (Figs 2 C–D: pr); posterior margin of sternum 4 medially protruded, with two tufts of black pile medially (Figs 2 C–D: t). Surstylus squared with apical protuberance and inner spine (marked with arrow on Fig. 3B); hypandrium as in Figs 3 C–D; paramere broad basally and tapering towards the rounded apex, with a lateral spine (marked with arrow on Figs 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 2 C–D: pr), as well as the posterior margin of sternum 4 medially protruded with two tufts of black pile medially (Figs 2 C–D: t). The aedeagus complex (Figs 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 2 A–B, 7A).

Thorax (Figs 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. 2A); scutellum black with golden sheen, covered with yellow pile, as long as the length of scutellum. Abdomen (Fig. 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. 2B); 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 2 C–D: pr); posterior margin of sternum 4 medially protruded, with two tufts of black pile medially (Figs 2 C–D: t). Terminalia (Figs 3, 4). Surstylus squared with apical protuberance and inner spine (Figs 3 A–B: s); hypandrium as in Figs 3 C−D, paramere broad at the base and tapering to the rounded apex, with lateral spine (marked with arrow on Figs 3 C–D); posterior rim of hypandrium differentiated into a wide lingula (Fig. 3C: l); ejaculatory apodeme on Fig. 3E.
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.

Western and Eastern Cape Provinces (Fig. 1).
