Materials Examined
Material studied. Holotype (TANZANIA) ♂: five original labels (Fig. 24): "Kilimanjaro / Tanganyika" [white, printed, "♂" [white, printed], "Wald ob.Machame / 2000-2500m / lg.H.Franz" [white, printed], " Pseudoeudesis / lindneri m. / det.H.Franz" [white, handwritten and printed], " Holotypus " [red, handwritten] (NHMW). Paratypes (2 specimens): 2 ♀♀ (one dry-mounted, one disarticulated and embedded in Canada balsam), same collecting data as holotype (NHMW).
Diagnosis
Diagnosis. Eyes present, rudimentary; aedeagus in ventral view with sides in subapical region rounded, endophallus with bell-shaped structure located in subapical region, with two lateral elongated and pointed sclerites of strongly unequal length.
Description
Description. Body of male (Fig. 2) elongate and slender, convex, with moderately long appendages, BL 0.68 mm; pigmentation light brown; vestiture of setae slightly lighter than cuticle. Head (Fig. 2) in dorsal view round, strongly convex, broadest near middle, behind eyes, HL 0.13 mm, HW 0.14 mm; tempora much longer than eyes; vertex short and broad, strongly convex, anteriorly confluent with frons; frons subtrapezoidal, strongly convex between eyes and rapidly declining anteriorly; supraantennal tubercles indistinct; eyes rudimentary, barely noticeable, each composed of two tiny ommatidia pigmented as lightly as surrounding cuticle. Vertex and frons with inconspicuous fine punctures and short, sparse, suberect setae. Antennae (Fig. 2) moderately long, slender, with three terminal antennomeres enlarged, AnL 0.28 mm; antennomeres I and II strongly elongate, III–VIII each slightly transverse, IX–X distinctly broader than long, XI much shorter than IX and X together, about as long as broad, with blunt apex. Pronotum (Fig. 2) in dorsal view oval, broadest near anterior third, PL 0.20 mm, PW 0.18 mm; anterior and posterior margins weakly rounded, lateral margins strongly and nearly evenly rounded; base lacking pits. Pronotal disc with fine and inconspicuous punctures; setae on dorsal part short, sparse and suberect, sides with dense bristles. Elytra oval, broadest anterior to middle, strongly narrowing both anteriorly and posteriorly; EL 0.35 mm, EW 0.25 mm, EI 1.40; basal impressions, subhumeral lines and humeral calli absent. Punctures and setae similar to those on pronotal disc. Hind wings absent. Legs (Fig. 2) moderately long and slender, unmodified. Aedeagus (Figs 17–18) thin-walled, elongate, in ventral view drop-shaped, with broadly subtriangular apical portion of median lobe and rounded sides in subapical region; AeL 0.13 mm; endophallus with subapical bellshaped structure and two elongate sclerites of strongly unequal lengths, the longer sclerite (in ventral view located to the left of the long axis of the median lobe) projecting through ostium; parameres long and slender, each with one apical seta. Female (Fig. 3). Similar to male; BL 0.75 mm; HL 0.14 mm, HW 0.15 mm, AnL 0.28 mm; PL 0.21 mm, PW 0.19 mm; EL 0.40 mm, EW 0.29 mm, EI 1.39.
Distribution
Distribution. Eastern Tanzania.
Discussion
Remarks. In the original description Franz (1963) stated that the type series was composed of five specimens, all from Machame (the south-western slope of Kilimanjaro), 20.07. 1962, three of them (including the holotype) collected at 2200–2300 m, and two at about 2600 m. In the Franz Collection at NHMW there are four specimens labeled as types (holotype and three paratypes) and one additional specimen without identification label but with the same locality labels as the holotype. However, only three specimens belong to Oreoeudesis, and these are certainly the three collected at 2200–2300 m (holotype male and two paratype females). The two remaining specimens are females and therefore they were not studied in detail, but they look different enough from the holotype to suggest that they do not belong in the same genus.
