Venezolanoconnus andinus Franz

( Figs. 59–61 , 65–66, 68–70 )

Venezolanoconnus andinus Franz, 1988: 81 ; Fig. 25 .

Material studied. Holotype: 3: four labels: "Bosque de la Carbonera / 2000 m, Umg. Merida / Venezuela, lg. Franz"" with "SA273" on the reverse side [white, printed; reverse handwritten], " Venezolanoconnus / andinus m. / det. H. Franz" [white, handwritten and printed], "3" [white, printed], " Holotypus " [red, handwritten] ( NHMW).

Diagnosis. This species can be identified on the basis of the pronotum only slightly broader than long and strongly narrowing anterad.

Redescription. Body of male ( Fig. 59 ) strongly convex, elongate but moderately slender, with moderately long appendages, BL 1.58 mm; glossy, uniformly light brown with slightly lighter palps; vestiture slightly lighter than cuticle.

Head ( Figs. 60–61 , 66 ) rhomboidal in shape, broadest at eyes, HL 0.25 mm, HW 0.35 mm; occipital constriction distinctly narrower than half HL; tempora much shorter than eyes, strongly convergent caudad; vertex strongly transverse, convex; frons confluent with vertex, slightly convex, subtrapezoidal and steeply, abruptly declining towards strongly transverse clypeus; supraantennal tubercles barely marked; eyes large and strongly convex, kidney-shaped and transverse in relation to the long axis of the head, each composed of ca. 50 small and smooth ommatidia. Dorsal punctures on head fine and sparse, inconspicuous; setae long, moderately dense, erect, those on vertex and tempora directed caudad. Antennae ( Fig. 59 ) slender, gradually thickening towards apices, AnL 0.63 mm; antennomeres I–II elongate; III–V each about as long as broad; VI–X each slightly transverse; XI 1.6× as long as broad, nearly symmetrical, with blunt subconical apex.

Pronotum ( Fig. 59 ) in dorsal view approximately subtrapezoidal, broadest in posterior third, PL 0.40 mm, PW 0.45 mm; anterior margin short and slightly arcuate; lateral margins strongly rounded, especially in posterior third, so that hind pronotal corners are not marked and sides form a regular arch with rounded posterior pronotal margin; base of pronotum without foveae. Punctures on pronotal disc very fine, inconspicuous; setae long, moderately dense and strongly erect, those on sides of pronotum bristle-like, distinctly thicker than those in middle.

Elytra ( Fig. 59 ) broadly oval and much more convex than pronotum, broadest distinctly behind middle, EL 0.93 mm, EW 0.78 mm, EI 1.19; base of elytra distinctly arcuate; humeral calli prominent, each sharply delimited mesally by subhumeral line as long as 0.4× EL; elytral apices separately rounded. Punctures on elytral disc more distinct and denser than those on pronotum but only superficial and with diffused margins; setae moderately long, moderately sparse and suberect, about as thin as those on vertex and distinctly thinner than those on sides of pronotum. Hind wings well-developed, twice as long as elytra.

Legs ( Fig. 59 ) moderately long and slender; all tibiae straight.

Aedeagus ( Figs. 68–70 ) moderately stout, AeL 0.15 mm, with indistinctly delimited, subtriangular apical part (possibly slightly distorted during the previous preparation in the only known male); internal structures strongly asymmetrical, with long and curved sclerite projecting apically; parameres very broad, with subapical groups of several setae.

Female. Unknown.

Distribution. Western Venezuela, Mérida State.
