Protoconnus comarapae Franz

( Figs 22 , 30–31 , 93 , 101 )

Protoconnus comarapae Franz, 1980: 196 , fig. 179a, b.

Type material. Holotype: BOLIVIA (Manuel María Caballero Province): ♂, three labels ( Fig. 93 ): "Nebelwald b. / Comarapa, Peru / lg.H.Franz" with "SA143" on the reverse side and "Peru" overwritten with "Boliv." [white, printed], " Protoconnus / comarapae / m. / det.H.Franz" [white, handwritten and printed], "Typus" [red, handwritten] (NHMW). Paratype: 1 ♂, same data as for holotype, and the standard yellow "Paratypus" label (NHMW).

Revised diagnosis. BL 0.93–0.95 mm; body relatively slender, elytra 1.56–1.64 times as broad as transverse pronotum; frons in male slightly impressed between supraantennal tubercles; vertex unmodified; pronotal base with distinct pits and groove; lateral pronotal carinae distinct in posterior third; humeral carinae rounded; aedeagus in ventral view very slender, nearly gradually narrowing from the broadest site of basal capsule to narrow and pointed apex, parameres in subapical region straight.

Redescription. Body of male ( Fig. 22 ) strongly convex, light brown with slightly darkened elytral suture, setae yellowish; BL 0.93–0.95 mm.

Head broadest at relatively small, moderately convex and coarsely faceted eyes, HL 0.18 mm, HW 0.23 mm; tempora in lateral view as long as about 3/4 of the longest diameter of eye; vertex distinctly convex, posterior margin of vertex demarcated from the 'neck' region by weakly elevated and rounded ridge laterally confluent with evenly rounded tempora; frons indistinctly impressed between prominent supraantennal tubercles. Punctures on frons and vertex inconspicuous; setae short, moderately dense and suberect. Antennae slender, AnL 0.43 mm, less than half as long as body, club distinctly delimited; antennomeres I and II each about twice as long as broad; III–X each transverse, XI slightly longer than X, about 1.1 × as long as broad.

Pronotum slightly transverse, subtrapezoidal, parallel-sided in posterior half; PL 0.25 mm, PW 0.28–0.29 mm.

Anterior margin weakly convex, lateral margins in anterior third strongly rounded, in posterior half straight; lateral carinae distinct in posterior third; transverse antebasal groove and pits distinct. Punctures on pronotal disc inconspicuous; setae sparse, short, suberect.

Elytra much more convex than pronotum, oval, broadest in front of middle; EL 0.50–0.53 mm, EW 0.45 mm, EI 1.11–1.17; humeral carinae indistinct, rounded. Punctures and setae similar to those on pronotum.

Legs moderately long and slender, unmodified.

Aedeagus ( Figs 30–31 ) very slender; AeL 0.23 mm; in ventral view basal capsule about as long as 1/3 of distal region, narrowed distad; distal region laterally confluent with sides of basal capsule, slender, subtriangular, with narrow and pointed apex, in lateral view its distal half distinctly recurved; in lateral view area above parameral bases forming a long subtriangular projection; parameres nearly parallel, each with one long apical and one very short subapical seta.

Female unknown.

Distribution. Central Bolivia ( Fig. 101 ).

Remarks. Protoconnus comarapae is most similar to P. bolivianus ; see remarks for the latter species.
