Aferos (s. str.) youngai sp. n. ( Figs. 29–30 )

Description

Male. Black. Antennomere 1 anteriorly and metacoxal spines brownish; pronotum rufous.

Head with shallow roundish impression behind antennal prominence. Antennal sockets separated by approximately half their transverse diameter. Eyes small (interocular distance nearly 6 times as long as the radius). Labrum transverse, almost straight anteriorly. Labial and maxillary palpi slender, with ultimate joints almost parallel­sided and flattened distally. Antennae widening distally, extending nearly to elytral mid­point, with antennomeres 3–11 flattened and almost parallel­sided; antennomere 3 2.4 times longer than antennomere 2 and 1.25 times shorter than antennomere 4; antennal pubescence sparse and decumbent.

Pronotum slightly (1.1 times) wider than long, with conspicuous median areola and relatively inconspicuous transverse carinae, more prominent near lateral margins; anterior margin convex; lateral margins almost parallel­sided, slightly incised posteriorly, with hind angles slightly produced laterally. Scutellum elongate, narrowing distally, rounded at apex.

Elytra long, 3.2 times longer than wide at humeri and 4.4 times longer than pronotum, slightly widening posteriorly, with 4 equally developed primary costae; interstices with double rows of irregular elongate cells. Minute and sparse pubescence distributed along longitudinal costae.

Legs relatively robust; metacoxae produced posteriorly into acute spines; tibiae curved; tarsomeres 1–4 with plantar pads.

Aedeagus with long, acute distally parameres, narrowed in the middle ( Figs. 29–30 ).

Length: 6.1–7.2 mm. Width (humerally): 1.5–1.9 mm.

Female. Similar to male, but more robust, antennae shorter and eyes smaller.

Type material

Holotype male: S. Afr., Tv., Nelshoogte, Knuckles Rocks For. , 25 º 47 ' S – 30 º 50 ' E, very wet for. litter, 11.II. 1987, Endrödy­Younga leg. ( TMNH); paratype female: S. Afr., Tvl, Uitsoek , Waterfall area , 25 º 16 ' S – 30 º 33 ' E, beating, 7.II. 1987, Endrödy­Younga leg. ( TMNH); paratype male: S. Afr., Tvl, Uitsoek , Grootkloof ind. for. 25 º 15 ' S – 30 º 33 ' E, Cussonia logs, 6.II. 1987, Endrödy­Younga leg. ( ICM).

Diagnosis

A. youngai sp. n. differs from the other species of Aferos by the coloration of antennomere 1 and long, acute distally and narrowed in the middle parameres of its aedeagus (Figs. 29–30).

Etymology

Named after Dr. Endrödy­Younga who collected the type series.
