Type material. Holotype: REPUBLIC OF CHAD: ♂, three labels (Fig. 2): "Douguia am Chari / Tschadrepublik / lg.H.Franz 1962" [white, printed], " Stenichnodes / saheliensis m." [red, handwritten], " Holotypus " [red, handwritten] (NHMW).
Revised diagnosis. This is the only known species of the nominotypical subgenus and can be identified using subgeneric characters and the unique aedeagus.
Redescription. Body of male (Fig. 1) elongate and slender, strongly convex, yellowish brown, covered with yellowish vestiture; BL 0.79 mm.
Head broadest at large, strongly convex and moderately coarsely faceted bean-shaped eyes, HL 0.10 mm, HW 0.15; tempora in dorsal view barely discernible; vertex weakly convex and anteriorly confluent with frons; frons flattened, its anterior portion in front of eyes subtriangular; supraantennal tubercles indistinct. Vertex and frons with shallow, superficial and diffused sparse punctures; setae fine, nearly recumbent. Antennae slender, AnL 0.30 mm; antennomeres I–II distinctly elongate, III slightly transverse, IV–VII each about as long as broad, VIII slightly transverse, IX–X distinctly transverse, XI about 1.2× as long as broad, with rounded apex.
Alloraphes Stenichnaphes Stenichnodes s. str. Stenichnodes (Parastenichnaphes)
notosternal sutures complete internalized anteriorly internalized anteriorly complete Pronotum (Fig. 1) bell-shaped, broadest near anterior third; PL 0.21 mm, PW 0.23 mm. Anterior margin and lateral margins in anterior half rounded; sides slightly concave behind middle; posterior margin weakly arcuate; posterior pronotal corners obtuse-angled and blunt; base with shallow but distinct transverse groove at each side deepened to form small and indistinct lateral pits and with external pair of indistinct pits not connected to groove. Punctures on pronotal disc inconspicuous, fine and sparse; setae sparse, short and recumbent to suberect.
Elytra (Fig. 1) more convex than pronotum, oval, broadest slightly anterior to middle; EL 0.48 mm, EW 0.35, EI 1.36; humeral calli weakly marked, elongate, basal impression on each elytron indistinct; apices separately rounded. Punctures on elytra slightly more distinct than those on pronotum but still fine, shallow and unremarkable; setae sparse, short, recumbent to suberect. Hind wings well developed.
Legs (Fig. 1) long and slender; all tibiae nearly straight.
Aedeagus (Figs. 6–7) elongate and thin-walled, with asymmetrical assemblage of short apical projections and truncate base with circular diaphragm internally connected to long apophysis; parameres absent; AeL 0.20.
Female. Unknown.
Distribution. Afrotropical: Chad Republic.
