Diagnosis

Neolindus parahermani sp. nov. resembles N. hermani in habitus and genitalia morphology. However, they can be distinguished by the structure of pPMS of aedeagus. Antiparameral apical arms of pPMS in N. parahermani are bifid with two acute processes, while in N. hermani , they end with a rounded tip ( Asenjo 2011: figs 9–10; Fig. 13F–I ).

Etymology

The specific epithet is the combination of ‘ para ’, a Latin prefix that means ‘similar’ or ‘equal’, and ‘ hermani ’ as the name of the species described by Asenjo (2011), N. hermani . It indicates the similarity of morphology between aedeagi of the two species. An adjective.

Epicranium with umbilicate, high density micropunctuation, setation with 2 pairs of FS and 1 pair of PFS, without OS. Gena with irregular surface, with depression from mandibular base to posterior margin of head, setation with 1 OT, MS, and POS; sockets of MS and POS umbilicate. Postgena with row of 3–5 setae in line from eye to gular suture; gular sutures not reaching posterior margin of head; anterior part of gula with 6–8 setae. Neck with foramen magnum occupying ¾ of occiput. Antenna thin, longer than head and pronotum combined ( Fig. 13A ); antennomeres longer than wide, tomentose pubescence starting from antennomere 4; antennomere 1 as long as 2 and 3 combined, antennomere 3 longer than 2. Labrum bilobed, with U-shaped emargination ( Fig. 13A ; Supp. file 2).

THORAX. Pronotum wider than long, with umbilicate micropunctures, 2 paramedial and 2 lateral rows of setae. Metasternal intercoxal process with pair of acute processes light brown at tips. Elytron longer than wide, surface of elytra with moderately dense umbilicate micropunctures in 8–10 longitudinal rows ( Fig. 13A ; Supp. file 2).

LEGS. Protibia with 5–6 well-developed combs of setae; mesotibial apical ctenidium on both sides, inner longer than outer; mesotarsomere 1 as long as 2, mesotarsomere 3 shorter than 1 and as long as 4, mesotarsomere 5 as long as mesotarsomere 1; inner ctenidium of metatibia longer than outer; metatarsomere 1 longer than metatarsomere 2, metatarsomere 3 shorter than metatarsomere 2, metatarsomere 4 as long metatarsomere 3, metatarsomere 5 as long as metatarsome 1.

ABDOMEN. Male: tergites with low-density random micropunctuation. Posterior margin of tergite VII straight ( Fig. 13B ). Posterior margin of sternite VII with wide midline emargination delimited with 2 long teeth-like processes with acute ends ( Fig. 13C ). Posterior margin of tergite VIII trilobed, with rounded middle lobe and triangle acute lateral lobes ( Fig. 13D ). Posterior margin of sternite VIII with broad midline emargination about ½ of segment length and 1 pair of longitudinal depressions on sides of midline emargination ( Fig. 13E ). Posterior margin of tergite IX with midlongitudinal deep emargination in ½ of segment length; aedeagus, in parameral view, median lobe slightly widened at apical part, apex with deep V-shaped emargination and with narrow flattened lateral processes adjacent to pair of lateral elongated ‘windows’ in membrane. pPMS elongated, complex, curved around longitudinal axis, with 2 apical arms almost fully fused and pointing distad and 1 apical arm short and bent laterad; bases of pPMS triangular, anchored in median foramen with internal sclerotised ring. pLS thin, slightly longer than pPMS and APS, with net-like microsculpture, forming elongate flat processes with lateral rounded lobes. APS spoon-shaped, with slightly emarginate top, shorter than pPMS ( Fig. 13F–I ). Female: unknown.

Distribution

This species is only known from the type locality in French Guiana (Roura, Réserve Naturelle Régionale Trésor). It was collected at a low altitude of 225 m a.s.l. using window trap.
