Diagnosis. Species with genae usually longer than antennal segment I. Afropictinus hylas sp. nov. is morphologically very similar to A. castor sp. nov., except for the characters given in the key.

Description. Glabrous and bicoloured, dark brown with yellowish parts of different extension on tergal plate and deltg III–VI. Head slightly longer than wide (15/14); genae longer than clypeus, reaching beyond apex of antennal segment I, bifurcate apex straight; antennae 1.61 times as long as width of head, segments I/II/III/IV = 6.5/3.5/7/5.5; postocular lobes rounded. Thorax with pronotum about 3 times as wide as long (20/7), paranota narrow and reflexed, only slightly produced anterolaterally; lateral margins subparallel at humeri converging anteriorly. Scutellum 2.7 times as wide as long (16/6). Mtg I+II fused, depressed at middle, separated from tergal disk by a distinct suture. Abdomen with tergal plate moderately elevated at middle; lateral margins of deltg V–VII slightly concave. Pygophore narrow, pear shaped. Female larger than male, genae somewhat shorter, yellowish colouration more extended on tergal plate. Measurements: Holotype male: length 3.05 mm; length of antennae 1.12 mm; ratio antennal segment III–II 2.0; width of abdomen 1.35. Female paratype: length 3.6 mm; antennae 1.56 times as long as width of head, length of antennae 1.25 mm, ratio segment III:II = 2.0; width of abdomen 1.7 mm.

Etymology. The species epithet is a Latinized Greek mythical name of Hylas , an Argonaut, abducted by water nymphs thus causing Heracles to search to him and miss departure of Argo; noun in apposition.

Distribution. This species is known from Tanzania: Kaguru Mts., Uluguru Mts. and West Usambara Mts.
