Parapseudoconnus (Neuraphomimus) simulator Franz

( Figs. 21 , 23 , 32–35 )

Pseudoconnus (s. str.) simulator Franz, 1980: 217 , Fig. 203.

Material studied. Holotype: 3: three labels ( Fig. 23 ): "Umg. Tarapoto / Peru, lg. Franz" with "SA137 [or /37]" on the reverse side [white, printed; reverse handwritten], " Pseudoconnus / simulator / 3 m. / det. H. Franz" [white, handwritten and printed], " Typus " [red, handwritten] (NHMW).

Diagnosis. Aedeagus with internal armature as in Fig. 35 .

Redescription. Body of male ( Fig. 21 ) moderately strongly convex and elongate, with moderately long appendages, BL 0.75 mm; glossy, uniformly light brown with slightly lighter appendages; vestiture slightly lighter than cuticle.

Head ( Figs. 21 , 32 ) approximately rhomboidal and slightly transverse, broadest at eyes, HL 0.15 mm, HW 0.18 mm; occipital constriction slightly broader than half HW; tempora slightly shorter than eyes, only slightly rounded and strongly convergent caudad; vertex distinctly broader than long, convex, only slightly (not conically) projected dorso-caudad, without postero-median impression; frons subtriangular, confluent with vertex; supraantennal tubercles weakly developed; eyes large and strongly convex, moderately coarsely faceted, kidney-shaped with deep posterior emargination, nearly transverse in relation to the long axis of head. Punctures on head dorsum fine and sparse, inconspicuous; setae moderately long, sparse, suberect to erect, those on vertex mostly directed caudad, thick bristles absent. Antennae ( Fig. 21 ) slender, with distinctly delimited club composed of antennomeres IX–XI, AnL 0.30 mm; antennomeres I–II elongate, III–VIII about as broad as long or only slightly elongate; VIII–X distinctly transverse; XI 1.7x as long as broad, slightly asymmetrical, with subconical, blunt apex.

Pronotum ( Fig. 21 ) in dorsal view sub-oval, broadest between middle and posterior third; PL 0.20 mm, PW 0.20 mm; anterior margin strongly arcuate; front angles rounded and indistinct; sides broadly rounded; hind angles moderately distinct and obtuse; posterior margin weakly arcuate; base of pronotum with shallow and small but distinct pair of external lateral pits, each adjacent to barely marked longitudinal sub-lateral carina. Punctures on pronotal disc fine and inconspicuous; setae long, sparse and suberect to erect, sides of pronotum with dense thick and very long bristles.

Elytra ( Fig. 21 ) oval and only slightly more convex than pronotum, broadest distinctly anterior to middle, EL 0.40 mm, EW 0.33 mm, EI 1.23; humeral calli distinct, developed as short longitudinal protuberances; basal impressions short but distinct, basal pits well-visible; elytral apices separately rounded. Punctures on elytral disc nearly as fine as those on pronotum; setae short and sparse, only slightly suberect. Hind wings well-developed, about twice as long as elytra.

Legs ( Fig. 21 ) moderately long and slender, without modifications.

Aedeagus elongate, AeL 0.11 mm, as in Fig. 35 .

Female. Unknown (see Remarks).

Distribution. Northern Peru, San Martin Province.

Remarks. The holotype male is accompanied in NHMW by a highly similar, but microphthalmous female labeled as Pseudoconnus ? simulator , and bearing the same collecting data. It is not possible to verify whether these specimens are conspecific or not without collecting a larger series composed of both sexes from the same spot. In the original description, Franz (1980) mentions that the type series is composed of a male holotype and female paratype, but in the Franz Coll. only this provisionally identified female is present, not labeled as paratype. In the original description Franz (1980) gives further collecting details: road Tarapoto-Yurimagua, 80 km from Tarapoto, between Pongo de Caimarachi and Shanussi, in litter of a bog or swamp forest ("Sumpfwald"), 0 1.10.1968.
