Adult male. Mounted material small, total body length 0.75–0.83 mm (Conchaspis capensis) to about 1.11 mm (Conchaspis angraeci). Head oval in dorsal view, broadest posterior to dorsal eyes, attached to thorax by a rather broad neck. Dorsal eyes subequal in width to ventral eyes, each 25–28 μm wide; ventral eyes placed anterior to dorsal eyes near scape. Preocular ridge rather short, extending dorsally from outer margin of each antenna to anterior margin of dorsal simple eyes. Dorsal ocular setae with 1–2 hair-like setae posterior to each dorsal simple eye. Antennae 7-segmented, segments III–VI quite elongate, each 20–24 μm wide; surface of each segment faintly reticulated; fleshy setae each 11–16 μm long. Mesothorax: prescutum almost oval to rectangular, 87–110 μm long, 124–140 μm wide. Tibia and tarsus fused; combined lengths: leg I 174–260 μm. Tarsal digitules each with a small apical knob, longer than claw. Abdomen: segments I–VII tergites and sternites probably unsclerotised; dorsal setae on each side of segments I–VII each with 2 pairs of small hair-like setae; ventral setae on segments II–VII each with 1–2 pairs of small hair-like setae. Segment VIII: tergite and sternite forming a sclerotised ring; tergite with 2–4 small hair-like dorsal abdominal setae on each side. Genital segment: segment IX fused to style, distinctly sclerotised; broad anteriorly (width 45–70 μm), abruptly narrowing into a long needle-like posterior part; aedeagus very long, of approximately equal width throughout.
