Diagnosis. The reduced wings ( Figs 40eView FIGURES 40 a – f, 96View FIGURES 94 – 97), 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. 96View FIGURES 94 – 97) 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. 94View FIGURES 94 – 97). 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. 96View FIGURES 94 – 97). 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. 95View FIGURES 94 – 97).

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. 96View FIGURES 94 – 97); in lateral view brown ( Fig. 97View FIGURES 94 – 97).

In dorsal view mesoscutum and mesoscutellum imbricate ( Fig. 96View FIGURES 94 – 97); 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. 97View FIGURES 94 – 97); metapleural carina with one posterior pointed. Metascutellum visible in dorsal view, wide with margins parallel to mesoscutellum ones, small metanotal spine ( Fig. 96View FIGURES 94 – 97).

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. 40eView FIGURES 40 a – f.

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. 96View FIGURES 94 – 97). T2 not foveolate in anterior margin, coriaceous in the rest of tergite.

Female: unknown
