Subgenus Parapseudoconnus View in CoL s. str.
The two subgenera were separated by Franz (1980) solely on the basis of differences in genital structures. However, all males of Parapseudoconnus in the Franz Coll. have the aedeagi distorted or damaged to some extent (probably also illustrations in Franz's papers show such distorted or incomplete preparations), and only the internal armature seems intact. In the present study some other characters were found to be different between the type species of Parapseudoconnus s. str. and the subgenus Neuraphomimus . Parapseudoconnus s. str. can be identified on the basis of the prothoracic hypomeral ridges obliterated in their anterior parts; indistinctly marked anterior margins of mesocoxal cavities; mesocoxal sockets located on meso-ventral surface of mesocoxal projections and therefore largely visible in ventral view; presence of small but distinct posterior lobes of mesocoxal projections; and the internal armature of the aedeagus without long and slender flagellum projecting distally beyond the median lobe.
Parapseudoconnus (Parapseudoconnus) aberrans Franz ( Figs. 19–20 View FIGURES 19 – 21 , 22 View FIGURES 22 – 25 , 26–31 View FIGURES 26 – 31 )
Pseudoconnus (Parapseudoconnus) aberrans Franz, 1980: 218 , Fig. 206.
Material studied. Holotype: 3: four labels ( Fig. 22 View FIGURES 22 – 25 ): "Umg. Manau / Amazongebiet / Brasil,lg.L.Beck" with "45" on the reverse side [white, printed; reverse handwritten], " Parapseudocon- / nus aberrans / m. / det. H. Franz" [white, handwritten and printed], "3" [white, printed], " Typus " [red, handwritten] (NHMW). Paratypes (6 exx.: 2 33, 4 ƤƤ): same data as for the holotype, one female laballed "Allotypus" [red, handwritten] (NHMW).
Diagnosis. Vertex in males and females with distinct postero-median impression; aedeagus with three elongate and curved sclerites.
Redescription. Body of male ( Fig. 19 View FIGURES 19 – 21 ) strongly convex and moderately elongate, with moderately long appendages, BL 0.84–0.86 mm (mean 0.85 mm); glossy, uniformly light brown with slightly lighter appendages; vestiture slightly lighter than cuticle.
Head ( Fig. 19 View FIGURES 19 – 21 ) approximately pentagonal and not elongate, broadest at eyes, HL 0.16–0.18 mm (mean 0.17 mm), HW 0.18–0.20 mm (mean 0.19 mm); occipital constriction much broader than half HW; tempora slightly shorter than eyes, rounded and gradually convergent caudad; vertex not projected dorso-caudad; broader than long, convex except for shallow postero-median impression; frons subtriangular and confluent with vertex; supraantennal tubercles weakly developed; eyes large and strongly convex, moderately coarsely faceted, kidneyshaped with deep posterior emargination, nearly transverse in relation to the long axis of head. Punctures on head dorsum fine and sparse, inconspicuous; setae long, sparse, suberect to erect, those on vertex mostly directed caudad, thick bristles absent. Antennae ( Fig. 19 View FIGURES 19 – 21 ) slender, with distinctly delimited club composed of antennomeres IX–XI, AnL 0.30 mm; antennomeres I–II elongate, III–VII each about as broad as long; VIII–X each strongly transverse; XI 1.4x as long as broad, slightly asymmetrical, with subconical, blunt apex.
Pronotum ( Fig. 19 View FIGURES 19 – 21 ) in dorsal view sub-oval, broadest between middle and posterior third; PL 0.23 mm, PW 0.23–0.25 mm (mean 0.24 mm); anterior margin weakly arcuate; front angles rounded and indistinct; sides broadly rounded; hind angles well-marked and obtuse; posterior margin weakly arcuate; base of pronotum with shallow and small but distinct pair of external lateral pits, each adjacent to short longitudinal sub-lateral carina. Punctures on pronotal disc fine and inconspicuous; setae long, moderately dense and suberect, sides of pronotum with dense thick and long bristles, especially in posterior half.
Elytra ( Fig. 19 View FIGURES 19 – 21 ) oval and only slightly more convex than pronotum, broadest slightly anterior to middle, EL 0.45–0.46 mm (mean 0.45 mm), EW 0.38 mm, EI 1.20–1.23 (mean 1.21); 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, suberect. Hind wings well-developed, about twice as long as elytra.
Legs ( Fig. 19 View FIGURES 19 – 21 ) moderately long and slender, without modifications.
Aedeagus ( Figs. 30–31 View FIGURES 26 – 31 ) elongate, AeL 0.13 mm, thin-walled, in two studied and previously dissected males slightly distorted during previous preparations, oval in shape, with internal armature composed of three elongate and curved sclerites.
Female ( Figs. 20 View FIGURES 19 – 21 , 26–29 View FIGURES 26 – 31 ). Similar to male but clearly differing in rudimentary eyes, each composed of a single ommatidium. BL 0.86–0.88 mm (mean 0.87 mm); HL 0.18 mm, HW 0.19 mm, AnL 0.28 mm; PL 0.24 mm, PW 0.24–0.25 mm (mean 0.25 mm); EL 0.45–0.46 mm (mean 0.45 mm), EW 0.38–0.39 mm (mean 0.38 mm), EI 1.16– 1.23 (mean 1.18).
Distribution. North-western Brazil, Amazonas State.
Remarks. Two specimens must be excluded from the type series of Parapseudoconnus aberrans due to misidentifications: one female belongs to the same genus but clearly differs in the general body shape and certainly is not conspecific with the holotype male; another specimen has not only a different body shape but also a distinct transverse groove on the pronotal base and belongs either to Euconnus or Protoconnus Franz. Both females were collected in a different site than P. aberrans , as evident from the numbers handwritten on the reverse side of locality labels (45 for P. aberrans and 32 and 38 for the two misidentified females). In the original description Franz (1980) indeed gave further collecting data that confirm this suspicion: the holotype and six paratypes were collected on the road to Pacaás Novas, 9.5 km from Guayara-Mirim, while two remaining specimens come from Reserve Ducke and Lago Janauaca near Manaus.
