Description. Body length 11–14 mm. Surface of body and all appendages unicoloured reddish brown, finely chagreened. Head with fine sparse punctation, with distinct transverse impression along clypeal suture, with a few long tactile setae between eyes; epistoma not trilobate, epistoma shovel-like with carinate anterior margin; labroclypeal membrane not exposed; last palpomere broadly triangular; antennae long filiform, reaching middle of elytra in males and anterior third of elytra in females, antenomere 3 1.3x longer than antennomere 4, terminal antennomeres 9–11 long oval; eyes reniform. Pronotum flat broad, without impressions, trapezoid, widest before posterior angles, posterior angles completely rounded, anterior corners feebly protruced; all margins finely bordered; with fine separated punctures as on head, without setation; propleura with the same smooth surface also without setation. Scutellum distinct visible. Elytra in males long, oval, in females distinctly broader; each elytron with 9 distinct punctural rows, internal rows in feeble striae, external rows without striae diminishing towards lateral margin, row 3 with approximately 36 punctures, punctures large and deep, lacking setae, scutellar striola not regular; elytral intervals in males narrow and slightly convex, in females wider and flat; humeral region without bump, humeral angle rounded, elytra minutely caudate, epipleura complete, impunctate. Wingless. Prosternum slightly prominent; metaventrite along anterior margin with impression, which bears rough, confluent punctation; anterior projection of first ventrite between hind coxae with impression, which bears strong longitudinal wrinkles, ventrites with fine punctures lacking setae, surface feebly wrinkled, last ventrite unmargined, without modification in both sexes; intersegmental membranes between ventrites not exposed. Legs very long; all femora long, clavate; anterior tibiae regularly widened toward apex, externally with distinct keel, fringed with a regular row of small dense spines, internal side with longer hairs; middle and posterior tibiae with longer hairs on inner side and irregularly set short spines on the external side with; all tibial spurs minute; anterior tarsomeres not widened in males, both sexes with dense yellow setation ventrally, basal protarsomere shorter than apical; basal metatarsomere longer than apical. Aedeagus as in Fig. 5. External sexual dimorphism expressed only in the shape of elytra, and in the convexity and width of the elytral intervals.
Etymology. Named in honour of Mrs. Robin Lyle, arachnologist at the Ditsong Museum Pretoria, and main collector of the type series.
