( Figs 1–6 ) Type material. Holotype : KENYA : ♂ , four labels: " KENYA : Tana River / Lac Shakababo , / près Ngao , 28.X.77 / Mahnert, Perret" [white, printed], " ♀ " [white with black margins, printed], "Parastenichnaphes / cf. sumatrensis m." / det. H.Franz " [white, handwritten and printed], " STENICHNODES (s. str.) / error m. / P. Jałoszyński , 2019 / HOLOTYPUS " [red, printed] ( NHMW ). Diagnosis. Aedeagus in ventral view with its distal half parallel-sided; antennomere X about as long as broad. Description. Body of male ( Fig. 1 ) elongate and slender, strongly convex, yellowish brown, covered with yellowish vestiture; BL 0.78 mm . Head broadest at large, strongly convex and relatively coarsely faceted eyes, HL 0.13 mm , HW 0.18 mm ; tempora vestigial; vertex weakly convex and anteriorly confluent with frons; frons flattened, its anterior portion in front of eyes subtriangular; supraantennal tubercles indistinct. Each eye bean-shaped, transverse in relation to the long body axis, with narrow posteromedian emargination. Vertex and frons with shallow, diffuse, inconspicuous punctures; setae fine, nearly recumbent. Antennae slender, AnL 0.35 mm ; antennomeres I–II strongly elongate, III slightly transverse, IV–X each about as long as broad, XI about 1.3 × as long as broad, much shorter than IX and X combined, with rounded apex. Pronotum bell-shaped, with sides parallel between base and anterior third; PL 0.20 mm , PW 0.20 mm . Anterior margin and sides in anterior third rounded; lateral margins in posterior 2/3 nearly straight; posterior margin weakly arcuate; posterior pronotal corners obtuse-angled and blunt; base with a shallow but distinct transverse groove, at each side deepened to form one pair of small and diffuse lateral pits. Punctures on pronotal disc inconspicuous, fine and sparse; setae sparse, short and recumbent to suberect. Elytra more convex than pronotum, oval, broadest distinctly in front of middle; EL 0.45 mm , EW 0.33 mm , EI 1.38; humeral calli distinct, elongate, basal impression on each elytron indistinct; apices separately rounded. Punctures on elytra slightly more distinct than those on pronotum, fine, shallow and inconspicuous; setae sparse, short, suberect. Hind wings well developed. Legs long and slender; unmodified. Aedeagus ( Figs 2–5 ) elongate and with thick ventral and dorsal walls, in ventral view median lobe parallel-sided in distal half, with narrow base, apex truncate and asymmetrically emarginate; AeL 0.25 mm . Female. Unknown. Distribution. South-eastern Kenya , eastern part of Tana River County ( Fig 6 ). Etymology. The new species is named error because the male holotype specimen has been identified by Herbert Franz, the author of Stenichnodes , not only as Parastenichnaphes cf. sumatrensis , but also as a female. FIGURES 1–6. Stenichnodes s. str. Dorsal habitus (1) and aedeagus in ventral (2, 4) and lateral (3, 5) views of Stenichnodes error sp. n. ; distribution of Stenichnodes s. str. species (6). Remarks. Stenichnodes error is externally similar to S. saheliensis ; only the antennae are slightly longer in relation to the body, distal antennomeres longer, and the pronotum has slightly different proportions. However, the aedeagi differ markedly; that of S. saheliensis (illustrated by Jałoszyński 2015a ) being much stouter, in ventral view fusiform, broadest near middle, whereas that of S. error has the distal half of the median lobe parallel-sided.
