Cryptolarynx endroedyi Haran sp. nov. urn:lsid:zoobank.org:act: 76B9D666-207A-4BC2-A344-844400B78F98 Figs 1T , 2T , 3T , 4T , 5T Differential diagnosis Cryptolarynx endroedyi sp. nov. differs from all other known species of the genus by its distinctly elongate body and by the following two features (in the male): the presence of depressions on the pronotum and elytra and the temones of the penis being almost twice as long as the penis body. Etymology We dedicate this species to the late Sebastian Endrödy-Younga, coleopterist at the Ditsong National Museum of Natural History (formerly the Transvaal Museum) from 1973 to 1999. The extent of his field collecting in South Africa and Namibia exceeds imagination with respect to the large numbers of species and of specimens he collected and the significant number of localities he surveyed. He also collected many of the specimens of Cryptolarynx and Hadrocryptolarynx gen. nov. reported in this study. The specific epithet is a noun in the genitive case.

Paratypes REPUBLIC OF SOUTH AFRICA – Western Cape • 2 ♀♀ ; same collection data as for holotype; TMSA • 1 ♀ ; same collection data as for holotype; CBGP . Description ( ♂ ) MEASUREMENTS . Body length 3.6 mm . COLOUR AND VESTITURE . Body integument black, antennae, tibiae and tarsi reddish. Dorsal vestiture (pronotum + elytra) consisting of overlapping, recumbent, parallel-sided clothing scales, 3–4× as long as wide, mostly truncate at apex; colour of scales mostly brown; whitish scales interspersed with pale brown scales concentrated laterally on pronotum and on elytra laterally from interstriae 4, white scales forming a pair of pale spots surrounded by dark scales at apical ⅔ of elytral interstriae 2–3; scales of striae recumbent, in lateral view not distinct from rest of vestiture. HEAD . Forehead slightly wider than epifrons near antennal insertions, scales suberect. Eyes convex, in dorsal view distinctly exceeding outline of head, surrounded by a ring of short pale scales, on forehead directed towards occiput; distance between eye and scrobe slightly smaller than width of antennal club. Epifrons with distance between antennal insertions 0.33 × length of scape, scales at least 2× as long as wide, recumbent, subcontiguous. Frons with 3 pairs of long erect lateral setae. Epistome without median seta. Antennal funicles with segments 1–2 elongate, subequal in length; 3–4 longer than wide; 5–6 globular; 7 wider than long. PRONOTUM . Transverse (W:L ratio 1.35), widest near midlength, sides arcuate; apex and base subequal in width; with a depression at midlength on either side of dark median longitudinal stripe. ELYTRA . Broadly ovate, longer than wide (W:L ratio 0.9), sides convex, widest anteriorly of midlength; with a slight depression on basal half of interstriae 1–2. LEGS . Slender. Tibiae with apical mucro; protibiae with outer margin straight, inner margin slightly bisinuate; metatibiae with inner setal fringe, the setae shorter than segment 5 of metatarsus. Tarsi with segment 2 isodiametric. ABDOMEN . Ventrites with creamy-white plumose scales not concealing integument; scales on ventrites 2–5 medially intermixed with long suberect setae, bifid or not at the apex; ventrite 1 slightly concave medially, impression covered with long setae deeply divided from their bases; ventrite 5 with scales concentrated in basal quarter. TERMINALIA . Body of penis moderately elongate (W:L ratio 0.5), 2× as short as temones, sides convex; in profile straight, downcurved near apex, dorsoventrally narrowed at apex. Copulatory sclerite weakly sclerotised or not discerned in examined specimen. Parameroid lobes separate, divided by modest median notch, each lobe broad, bearing a series of setae directed apicad. Spiculum gastrale with basal arms long, regularly curved. Sexual dimorphism The sexes can be distinguished by the shape of the elytra (shorter in the male) and by ventrite 1 lacking the long and deeply divided setae in the female. Life history Specimens of Cryptolarynx endroedyi sp. nov. were collected in a flowering meadow. No data about any host plant association of the species are available. Distribution The species was only found at the type locality, the Clanwilliam area in the Western Cape province ( Fig. 13 ).
