Afrothaumalea stuckenbergi Sinclair 2015, sp. n.

Afrothaumalea stuckenbergi sp. n. Figs 1, 3–10 Etymology: The specific name is a patronym in honoUr of Dr Brian StUckenberg, who collected the first African specimens of ThaUmaleidae. Recognition:This species is distinguished from the other two species of Afrothaumalea by the stout, blunt setae on the gonostyli, R 4+5 and M 1 running parallel, and female terminalia with elongate cerci and stout setae on the apex of the hypogynium. Description: Adult. Coloration (Fig. 1): Head dull, dark brown. Mesonotum dark reddish brown, abdomen dark brown and dull; katepisternum, coxae, femora and tibiae pale brown, tarsi darker; halter knob dark brown; terminalia dark reddish brown. Thorax: Scutum above wing base not developed into ridge. All legs with deeply bilobed tarsomere 4 in dorsal view; ventral face with dense whitish pubescence. Tarsal claw very long, nearly subequal in length to tarsomere 5. Wing (Fig. 5): Length 2.5–2.8 mm; infuscate, darker on basal third; R with macrotrichia in two scattered rows, R 1 and R 1 (+R 2+3) with sparse row of microtrichia along entire length, remaining veins bare; R flexed into cell br, flexUre sclerotised and dividing bm cell into two separate cells; R 2+3 crossvein apparently absent; distinct bend in R 4+5 lacking; R 4+5 and M 1 running parallel to wing margin. Abdomen: Male sternites 2–7 rectangular with anterior margin well sclerotised, bearing microtrichia and nUmeroUs setUlae. Sternite 8 Unmodified, bearing setUlae; anterior margin straight, transverse; posterior margin attenuated medially, parallel with hypandrium. Male terminalia (Figs 8, 9): Epandrium subtriangular, wider than long; posterior margin pointed medially; lacking posterolateral epandrial processes. Hypandrium very narrow and slender. Gonocoxite quadrate, slightly longer than wide with short triangUlar process on posterolateral margin medially. Gonocoxal blade finger­like, half-length of gonocoxite, arched medially, cruciate with opposite blade tip; tapered with rounded tip. Gonostylus very broad, paw-like, expanded somewhat apically; shorter than gonocoxite; arched medially with inner margin bearing long peg-like setae; tips of pegs trUncate. Parameres paired, straight, flattened; angled medially; apex trUncate; extending to apex of gonostylus. Cercus apparently greatly reduced, not setose or padlike; proctiger comprises 3 pairs of sclerotised rods. Female terminalia (Fig. 10): Sclerites of segment 8 connected anterolaterally by internal sclerotised apodeme. Hypogynial valve elongate, bearing dense spine-like setae, projecting beyond tergite 9. Tergite 9 quadrate in lateral view, longer than tergite 8. Cercus prolonged posteriorly, longer than wide, projecting posterodorsally. Pupa. Length 3.0– 3.2 mm (Figs 3, 6, 7). Dorsoventrally flattened, rectangUlar in cross­section with distinct lateral sclerite on abdominal segments, broadest at abdominal segment 4; maxillary sheath short, posteromedially-directed, apices of palpi separated medially; fore and mid leg sheaths projecting straight and slightly beyond wing sheaths; hind leg S-shaped beneath wing, projecting along posterior margin of wing sheath. Respiratory organ short, cylindrical, truncate apically, with spiracular openings encircling apex; abdomen with lateral open spiracles on segments 5–7, spiracles directly dorsally. Caudal segment truncate, lacking hook-like process. Chaetotaxy lost during preservation. Larva. Length 6–7.5 mm (Fig. 4). See Sinclair and Stuckenberg (1995) for description. Key generic features include: cone-like protuberances on head capsule absent; mesonotum and metanotum with blade-like macrosetae; conical lobes on either side of posterior spiracular plate absent. Holotype: ♂ “ RSA: Western Cape / Cederberg Wilderness / DUiwelsgat near at:/ 32°24.086'S 19°05.268'E / 16.ix. 2013, 693 m/ leg. A.H. Kirk­Spriggs / ex. rock seepage”; “HOLOTYPE/ AfrothaUmalea / stUckenbergi/ Sinclair [red label]” (BMSA). Paratypes: Same data as holotype (11 ♂, 8 ♀, BMSA, CNC, NMSA). Distribution: Known only from the type locality (Fig. 2). The Cederberg range lies 200 km north of Cape Town and is part of the Cape Fold Belt, consisting mainly of Table Mountain sandstone. Most rains fall between May and September, and vegetation is predominantly mountain fynbos.The Cederberg Wilderness received World Heritage status in 2004. Key to males of Afrothaumalea (Females are not included in the key because they are generally poorly known, although A. stuckenbergi possesses what appears to be distinctly shaped terminalia). 1 R 4+5 and M 1 running parallel to wing margin (Fig. 5).
