Diagnosis

Neolindus tropicalis Guzman, Tokareva & Żyła sp. nov. has a very close structure of aedeagus to those of N. lodhii , but can be distinguished by the combination of the following characters: posterior margin of sternite VII with acute processes on each side of emargination (absent in N. lodhii ), lobes of posterior margin of sternite VIII without longitudinal straight rows of short black setae (present in N. lodhii ) and without short median carina between the lobes of sternite VIII (present in N. lodhii ) ( Herman 1991: figs 182, 187; Fig. 21C, E ).

Etymology

The name is derived from the Latin word ‘ tropicus ’, which refers to the tropics. It indicates that the species type locality is in tropical Brazil. An adjective.

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

HEAD. Head capsule wider than long; anterior margin sinuate, bent dorsoventrally, slightly elevated; posterior margin rounded with emargination in front of neck; posterior angles straight; setation with 1 pair of PCS and 1 row of PMS. Epicranium shiny and smooth, without micropunctuation, setation with 1 pair of OS, and 1 pair of PFS, without FS. Gena with irregular surface, with depression from mandibular base to middle of eye, setation with 1 OT, MS, and POS; sockets of MS and POS umbilicate. Postgena with row of 3 setae in line from eye to gular suture; gular sutures not reaching posterior margin of head; anterior part of gula with 2 setae; posterior margin of head with 2 setae close to gular sutures. Neck with foramen magnum occupying ¾ of occiput. Antenna moniliform from antennomere 5, shorter than head and pronotum combined ( Fig. 21A ); 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 V-shaped emargination ( Fig. 21A ; Supp. file 2).

THORAX. Pronotum slightly wider than long, with umbilicate micropunctures and 3 longitudinal rows of seta, 1 median and 2 lateral. Metasternal intercoxal process with 1 pair of acute processes with light brown tips. Elytron longer than wide; surface of elytra with umbilicate micropunctures in 6–8 moderately dense longitudinal rows ( Fig. 21A ; Supp. file 2).

LEGS. Protibia with 4 well-developed combs of setae, apical comb with wider spaced and thicker longitudinal 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 1; inner ctenidium of metatibia longer than outer.

ABDOMEN. Male: tergites with low density of micropunctuation. Posterior margin of tergite VII straight ( Fig. 21B ). Posterior margin of sternite VII with moderate deep emargination flanked by acute processes on each side ( Fig. 21C ). Posterior margin of tergite VIII with single broad, triangular lobe with rounded tip ( Fig. 21D ). Posterior margin of sternite VIII with midline broad emargination, of about ¼ of segment length, lateral angles obtuse ( Fig. 21E ). Posterior margin of tergite IX with midlongitudinal deep emargination in ¾ of segment length ( Fig. 21A ); aedeagus, in parameral view, median lobe with consistent width throughout, apex emarginate with rounded sclerotised processes on each side; pPMS conical, sclerotised, slightly bent towards each other, shorter than pLS and APS. pLS partially sclerotised, narrow, flattened; APS longer than pLS and pPMS, apically divided in 2 partially membranous arrowlike processes ( Fig. 21F–I ). Female: unknown.

Distribution

The species is known only from the type locality in Brazil (Amazonas, Manaus, Reserva Florestal Adolpho Ducke). It was collected at a low altitude.
