Differential diagnosis
Cryptolarynx pilipes sp. nov. can be distinguished from other species of the genus by the combination of the inner fringe of elongate setae on the metatibiae and the suberect scales on the epifrons.
Etymology
The species name pilipes is derived from the Latin nouns ‘ pilus ’ (‘hair’) and ‘ pes ’ (‘foot’) and refers to the fringe of long setae on the metatibiae of the species. The specific epithet is a noun in apposition.

Description (♂)
MEASUREMENTS. Body length 3.4–3.7 mm.
COLOUR AND VESTITURE. Body integument black, antennae and tarsi reddish. Dorsal vestiture (pronotum + elytra) consisting of overlapping, recumbent, parallel-sided clothing scales, at least 2 × as long as wide, truncate or rounded at apex; colour of scales varying from white to pale brown to dark brown, white scales concentrated laterally on pronotum and at base of elytral interstriae 4 and forming a pair of subcontiguous white spots surrounded by dark scales at apical ⅔ of interstriae 1–4; scales of striae recumbent, in lateral view not distinct from rest of vestiture.
HEAD. Forehead wide, 1.5× wider than epifrons near antennal insertions, 1.25 × as wide as width of an eye, scales suberect. Eyes convex, in dorsal view slightly exceeding outline of head, surrounded by a ring of short pale scales, on the forehead directed towards occiput; distance between eye and scrobe as large as width of antennal club. Epifrons with distance between antennal insertions 0.5× length of scape, scales at least 2 × as long as wide, suberect, contiguous. Frons with single pair of erect lateral setae. Epistome without median seta. Antennae with funicle segment 1 elongate; 2 slightly shorter, at most 2× as long as wide; 3–5 longer than wide, compressed; 6–7 globular, isodiametric.
PRONOTUM. Transverse (W:L ratio 1.5), widest near midlength, sides arcuate; width of apex ⅔× width of base.
ELYTRA. Globular, slightly wider than long (W:L ratio 1.1), sides convex, widest near midlength.
LEGS. Protibiae with both outer and inner margins straight; pro- and mesotibiae with small apical mucro, metatibiae amucronate; metatibiae with inner fringe of setae as long as segment 5 of metatarsus. Tarsi with segment 2 wider than long.
ABDOMEN. Ventrite 1 medially with broad, semicircular concavity with deeply divided, plumose scales; ventrites 2–4 with creamy-white plumose scales, partly concealing integument, intermixed with long suberect scales; ventrite 5 with erect setae.
TERMINALIA. Body of penis elongate (W:L ratio 0.3), slightly shorter than temones, sides subparallel, converging strongly near apex; curvature in profile weak and regular, dorsoventrally narrowed at apex. Copulatory sclerite weakly sclerotised or not discerned in examined specimens. Parameroid lobes separate, divided by deep median notch, each lobe broad, rounded at apex, bearing a series of long setae directed apicad, setae as long as depth of median notch. Spiculum gastrale with basal arms short, regularly and moderately curved, laterally slightly angulate.
Sexual dimorphism
Female unknown.
Life history
Adults of C. pilipes sp. nov. were collected in October, from Arctotheca calendula (L.) (Asteraceae).
Distribution
The species was found only at the type locality, Clanwilliam in the Western Cape province (Fig. 13).
