Type species

Pseudostegopterus melolonthinoides gen. et sp. nov.

Diagnosis

This new genus differs from all other Trichiini genera occurring in South Africa by the following combination of diagnostic characters: 1) The eye-canthus covers about ½ of the ocular hemisphere; 2) the frons and vertex are covered with thick, long, inclined, testaceous setae; 3) the length of the pronotum is <0.5 times that of the elytra; 4) the posterior pronotal margin does not exhibit any ridge centrally; 5) the pronotal surface is generally covered with thick, long, inclined, testaceous setae; 6) the pronotal posterior corners are obtuse; 7) the elytral apex is rounded; 8) the elytral lateral ridge is visible on the entire lateral border; 9) the elytra cover the entire pygidium, except its very apex; 10) the length of protarsal claws is 0.70–0.90 times that of the last tarsomere; 11) the mesotibia are slightly curved outwardly; 12) the metatibia exhibits two spurs; 13) the first metatarsal segment is as long as the second or shorter; 14) the metatibial apex is strongly enlarged; 15) the internal corner of the metatibial apex is deprived of long spines; 16) the mesosternal process is absent; 17) the metafemur width is 0.4–0.45 times its length; 18) the males are fully winged.

Etymology

The name comes from its superficial resemblance to some representatives of the genus Stegopterus Burmeister & Schaum, 1840 .
