Etymology. The name is a combination of nolukhanyo–, the Xhosa name for the village of Bathurst, for the type locality and –ensis (L. suffix denoting place).

Ventral thoracic segments ochraceous marked with piceous on basisternum 2, medial anepisternum 2, katepisternum 2, medial katepimeron 2, medial meron 2, basisternum 3, medial half of episternum 3, and medial trochantin 3, markings reduced in some paratypes, covered with long, dense white and silvery pile.
Wings. Fore wings and hind wings hyaline with eight and five apical cells respectively. Venation ferruginous at base becoming testaceous distally, ferruginous replaced with ochraceous in some paratypes, piceous on proximal radius & subcostal vein along basal cell, arculus, proximal anal vein 2 + 3, and spot on node, spot on node reduced or absent in some paratypes. Pterostigma absent. Basal membrane of fore wing white with gray posterior margin. Hind wing venation ochraceous, darkening distally, except piceous cubitus anterior and proximal anal vein 3. Entire anal cell 3 and anal cell 2 along anal vein 3 light gray, anal cell 2 and anal cell 1 light gray along anal vein 2.
Legs. Legs greenish ferruginous, coxae, trochanters, and femora, striped with piceous, fore tibiae castaneous, middle tibiae castaneous near distal terminus. Fore femora with four oblique spines, proximal longest, secondary intermediate in length, secondary spine parallel to the primary spine, more erect in some paratypes, tertiary spine smallest and most angled, with very small apical spine extending from base of tertiary spine, all piceous with castaneous tips. Fore tarsi castaneous, middle tarsi lighter in the middle, hind tarsi greenish with castaneous proximal and distal margins, tibial spurs and comb ground color with darker tips. Pretarsal claws light castaneous. Legs radiating long silvery pile.
Operculum. Male operculum with smoothly curved lateral and posterior margins, domed near base, lateral side bent dorsally at approximate right angle, reaching to middle of sternite II, ochraceous with piceous lateral margin, reddish along margin with meracanthus, long silvery pile radiating from operculum, denser at base. Medial margins reaching to lateral hind trochanter, separated by ventral extension of sternite I, curved with straight anterior margins forming a slightly acute angle. Meracanthus triangular, ochraceous with reddish base and piceous spot on base, extending over anterior margin of operculum.
Abdomen. Abdominal tergites 1 and 2 piceous, tergites 3–8 piceous with transverse ferruginous mark on posterior dorsolateral and lateral areas and ochraceous posteromedial and lateral margins, amount of ferruginous area increasing in posterior tergites so that posterior third of tergite 8 ferruginous, ferruginous replaced with castaneous in some paratypes, tergites covered with long and short silvery pile. Timbal cover absent, timbal completely exposed, timbal with five ribs, extending to wing base. Male sternites and epipleurites ochraceous except piceous sternite I, midline and anterior margin of lateral sternite II, ventrolateral sternite II ferruginous anteriorly, ochraceous posteriorly. transverse piceous fascia on anterior midline of sternite III, sternites III–VI with longitudinal triangular castaneous mark on midline and ferruginous lateral margin, castaneous in some paratypes, ferruginous spot on anteromedial epipleurites, castaneous in some paratypes, sternite VII an elongated triangle, ferruginous spot on posterolateral margin in some paratypes, sternite VIII slightly elongated, ochraceous with ferruginous spot on lateral base, light castaneous tip in some paratypes, radiating castaneous pile, denser posteriorly, U-shaped when viewed from posterior.
Genitalia. Male pygofer piceous dorsally with ferruginous lateral surfaces and ochraceous ventral margins, distal shoulder undeveloped, dorsal beak very small, pointed, bent ventrally when viewed from the side. Upper pygofer lobe lobate triangle, radiating long silvery pile, dense where upper pygofer lobe and distal shoulder meet, connection to dorsal beak straight, pygofer basal lobes elongated, flattened, adpressed to pygofer, curving sharply into upper pygofer lobe with long golden pile radiating medially from margin. Anal styles dark castaneous, anal tube ochraceous dorsally, dark castaneous ventrally. Median uncus lobe piceous, short, flattened, roughly semicircular when viewed from above. Claspers well developed, castaneous, base with parallel sides meeting along midline under median uncus lobe, bent at approximate right angle, tapering and diverging laterally to separate points, recurving anterolaterad towards base at apex when viewed from the side. Aedeagus tubular, castaneous, restrained by claspers.
Female currently unknown.
Measurements (mm). Male. N = 12, mean (range). Length of body: 11.29 (10.1–11.9); length of fore wing: 11.73 (10.7–12.2); width of fore wing: 4.85 (4.7–5.0); length of head: 1.77 (1.6–1.9); width of head including eyes: 3.65 (3.5–3.8); width of pronotum including suprahumeral plates: 3.96 (3.7–4.3); width of mesonotum: 3.56 (3.4–3.8).
Diagnosis. This new species can be distinguished I. irhiniensis n. gen., n. sp. by the medial operculum margin roughly triangular and the pronotum with an elongated triangular mark on midline near anterior margin in that species. Ingcainyenzane umgeniensis n. gen., n. sp. can be distinguished by the timbal extending below the wing base, male sternite VIII is longer than the pygofer, and the short pygofer upper lobe of this new species.
Distribution. The species was collected in the Upper Kowie River catchment, South Africa (Heydon and Grindley 1982) near the town of Bathurst.
Notes on the biology of the species. We collected the species in the Albany valley thicket (AT18) of Dayaram et al. (2019). This species called from grasses and low shrubby plants.
