Diagnosis

Neolindus paraplectrus Guzman, Tokareva & Żyła sp. nov. is most similar to N. plectrus by the morphology. However, N. paraplectrus can be distinguished by the straight posterior margin of abdominal sternite VII, which is widely emarginate in N. plectrus ( Fig. 14C ; Herman 1991: fig. 83) and the median lobe of aedeagus with tapering triangular apex with additional ridge outlining the triangle, absent in N. plectrus ( Herman 1991: fig. 81; Fig. 14F–G ).

Etymology

The specific epithet is the combination of ‘ para ’, a Latin prefix that means ‘similar’ or ‘equal’, and ‘ plectrus ’ as the name of the species described by Herman (1991), N. plectrus . It indicates the similarity of morphology between the aedeagi of these species. An adjective.

COLOURATION. Head and pronotum dark brown; legs brown; abdomen dark brown.

HEAD. Head capsule wider than long; anterior margin sinuate, dorsoventrally deflexed, slightly elevated; posterior margin rounded with emargination in front of neck; posterior angles rounded; setation with 1 pair of PCS and 1 row of PMS clustered in middle. Epicranium convex, elevated above gena, with low-density micropunctuation in first part of head, setation with 1 pair of OS, without FS and PFS. Gena with smooth surface, with depression from mandibular base to posterior margin of head, setation with 2 trichobothria, MS close to antennal incisions, sockets of POS and PTOS umbilicate. Postgena with row of 3 setae in line from eye to gular suture; gular sutures reaching posterior margin of head joining neck pits; anterior part of gula without setae, with lateral invaginations; midlength of gula with 2 setae; posterior margin of head with 2 setae close to gular sutures. Antenna moniliform from antennomere 5, shorter than head and pronotum combined ( Fig. 14A ); antennomeres 1–4 longer than wide, antennomeres 5–11 wider than long, tomentose pubescence starting from antennomere 4; antennomere 1 as long as antennomeres 2 and 3 combined, antennomere 2 longer than 3. Labrum with multiple lobes and 1 wide quadrate emargination, marginal clypeal setae of equal lengths ( Fig. 14A ; Supp. file 2).

THORAX. Pronotum slightly longer than wide, with umbilicate randomly distributed micropunctures and irregular setation. Prosternal basisternum with longitudinal carina and smooth surface. Mesosternum with scutiform basisternum with scarce tuberculate micropunctuation. Mesanepisternum smooth, transversely convex. Metasternal intercoxal process with 1 pair of rounded processes. Elytron wider than long, shorter than pronotum; surface of elytra with umbilicate micropunctures in 8–9 moderately dense longitudinal rows ( Fig. 14A ; Supp. file 2).

LEGS. Protibia with 3 well-developed combs of setae, one of combs with thickened spines-like setae; mesotibial apical ctenidium on both sides, spines-like; mesotarsomeres 1, 2 and 3 as long as mesotarsomere 4, mesotarsomere 5 as long as mesotarsomeres 1–4 combined; inner ctenidium of metatibia longer than outer; metatarsomeres 1 to 4 subequal, metatarsomere 5 as long as metatarsomeres 1–4 combined.

ABDOMEN. Male: abdomen gradually widened towards segment VII. Tergites with low density of micropunctuation. Posterior margin of tergite and sternite VII straight ( Fig. 14B, C ). Posterior margin of tergite VIII elongate, rounded ( Fig. 14D ). Posterior margin of sternite VIII with midlongitudinal V-shaped emargination, and longitudinal glabrous invagination with carinated margin in middle part of emargination, lateral angles rounded ( Fig. 14E ). Posterior margin of tergite IX with midlongitudinal deep emargination in ¾ of segment length, fused; aedeagus, in parameral view, median lobe elongated, gradually narrowed towards apex; apex of lobe with triangular tapering process with additional ridge outlining triangular area. pPMS and pLS absent. APS long, spoon-like, flattened, shorter than median lobe, partially covering median foramen ( Fig. 14F–I ). Female: unknown.

Distribution

This species is known only from the type locality in Venezuela (Merida, Tabay). It was collected in a cloud forest in Sierra Nevada National Park at a high altitude between 2300–2700 m a.s.l.
