Diagnosis. The reduced wings ( Figs 40e , 96 ), the shape of the metascutellum, which is wide and visible in dorsal view with a small metanotal spine and the sculpture of T1 and T2 ( Fig. 96 ) distinguishes this species from D. antananarivensis , D. madagascarensis , D. sulawensis and D. tanzaniensis ; the presence of a preoccipital lunula separates this species from D. comitans and D. ndokii . Dyscritobaeus kilimajarensis Tortorici et Caleca sp. nov. differs from D. tanzaniensis by the presence of the metascutellum and sculpture of T1. The species differs from D. bicolor , D. flavus and D. parvipennis by the sculpture of T1 and its brachypterous wings.

Description. Male. Length of the body: 1.01 mm.

Head. Color dark brown. Coriaceous; head covered by hairs, mandibles yellow. Frontal depression not completely smooth; central keel absent ( Fig. 94 ). Fan-like striation in malar area from oral foramen to eye margin, fan-like striation present in genal area but not reaching half-length of malar sulcus. Malar sulcus length: 0.14 mm. Preoccipital lunula present and sculptured ( Fig. 96 ). Head measures width: height: length= 0.45: 0.37: 0.21 mm. Eye measures width: length = 0.13: 0.17 mm. OOL: LOL: POL= 0.12: 0.08: 0.12 mm. Mandibles bidentate with a small odontoid process ( Fig. 95 ).

Antenna. Radicles and scape light brown; A 3 – A 12 brown ; A 1 length: 0.22 mm ; A 2 longer as A 3 ; A 11 : A 12 ratio= 1: 2.

Mesosoma. In dorsal view, mesoscutum brown; mesoscutellum brown with posterior margin yellow; propodeum brown to yellow in lateral margin; metascutellum and metanotal spine brown ( Fig. 96 ); in lateral view brown ( Fig. 97 ).

In dorsal view mesoscutum and mesoscutellum imbricate ( Fig. 96 ); in lateral view speculum with furrow; femoral depression smooth with fan-like striation starting by post-ventral angle; posterior mesepimeral area not well delimitate anteriorly; dorsal and ventral metapleural area with crenulate depression with rugae ( Fig. 97 ); metapleural carina with one posterior pointed. Metascutellum visible in dorsal view, wide with margins parallel to mesoscutellum ones, small metanotal spine ( Fig. 96 ).

Mesonotum length 0.24 mm, width 0.42 mm; mesoscutellum length 0.15 mm, width 0.31 mm.

Wings. Fore wing hyaline, brachypterous, length not sourpassing T1; sm: 0.27 mm; wing width 0.11 mm, length 0.36 mm. as in Fig. 40e .

Legs yellow except hind coxe light brown.

Metasoma. In dorsal view metasoma brown. On T1 pair of longitudinal submedial carinae are oblique and separate lateral coriaceous microscupture and internal smooth and shiny area ( Fig. 96 ). T2 not foveolate in anterior margin, coriaceous in the rest of tergite.

Female: unknown

Comment and variability. Seven specimens were examined from Africa.

Size of the body homogenous in all this species.

All specimens were collected at high altitude (more than 1800 m a.s.l.).
