(36), holotype males. Head in ventral view (32); prothorax in ventral view (33); pterothorax in ventral view (34); aedeagus of holotype (35–36) in ventral or dorsal view (see Material and Methods). Abbreviations: ai, asetose impression; ar, anterior ridge; bs, basisternal part of prosternum; cd, cardo; gal, galea; gen, gena; gp, gular plate; gs, gular suture; fo, foramen occipitale; h, hypostoma; hr, hypostomal ridge; hy, hypomeron; hyr, hypomeral ridge; lac, lacinia; lp, labial palp; lmfa, lateral arm of metafurca; mcp, mesocoxal projection; md, mandible; mn, mentum; mscc, mesocoxal cavity; mscs, mesocoxal socket; mst, mesostipes; msvp, mesoventral intercoxal process; mtvp, metaventral intercoxal process; mxp, maxillary palp; nr, nss, pronotosternal suture; occ, occipital constriction; par, projection of anterior ridge; pc, prosternal intercoxal carina; pcc, procoxal cavity; pcs, procoxal socket; pf, profurca; pff, profurcal fovea; ppf, palpifer; pre, prepectus; ptp, posterior tentorial pit; smn, submentum; vIII, metaventrite; vlf, ventro-lateral fovea.
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
