Diagnosis

Neolindus longithorax Guzman, Tokareva & Żyła sp. nov. resembles N. bidens in the structure of tergite VIII as well as the broader median lobe of the aedeagus. However, the posterior margin of tergite VIII in N. longithorax differs from that of N. bidens with a more prominent central lobe and less developed lateral lobes ( Herman 1991: fig. 221; Fig. 6D View Fig ). Additionally, the aedeagus of N. longithorax has narrower and more elongate median lobe without median hole, contrasting with robust and medially widened median lobe with distinct median hole on parameral side of aedeagus in N. bidens ( Herman 1991: fig. 222; Fig. 6F–G View Fig ).

Etymology

The specific epithet is a combination of Latin words ‘ longus ’ meaning ‘long’ and ‘ thorax ’ as an anatomical part of an insect and refers to relatively long thorax of this species. An adjective.

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. Epicranium with umbilicate, low-density micropunctuation, setation with 1 pair of FS and 1 pair of PFS, without OS. Gena with irregular surface, with depression from mandibular base to middle of eye, setation with 1 OT, MS, POS, and PTOS; sockets of all setae umbilicate. Postgena with row of 2 setae in line from eye to gular suture; gular sutures reaching posterior margin of head joining neck pits; anterior part of gula with 2 setae; posterior margin of head with 2 setae near gular sutures. Neck with foramen magnum occupying ¾ of occiput. Antenna moniliform from antennomere 4, longer than head and pronotum combined ( Fig. 6A View Fig ); antennomeres longer than wide, tomentose pubescence starting from antennomere 4; antennomere 1 as long as antennomeres 2 and 3 combined, antennomere 3 longer than 2. Labrum bilobed, with V-shaped emargination ( Fig. 6A View Fig ; Supp. file 2).

THORAX. Pronotum quadrate, with umbilicate randomly distributed micropunctures absent in medial longitudinal line. Metasternal intercoxal process with 1 pair of minute rounded processes. Elytron longer than wide, surface of elytra with moderately dense umbilicate punctures in 8–10 longitudinal rows ( Fig. 6A View Fig ; Supp. file 2).

LEGS. Protibia with 4 well-developed combs of setae; apical comb longitudinal, composed of widely separated, thick setae; mesotibial apical ctenidium on both sides, inner longer than outer; mesotarsomere 1 longer than 2, mesotarsomeres 3 and 4 as long as 2, mesotarsomere 5 longer than 1; inner ctenidium of metatibia longer than outer; metatarsomere 1 longer than metatarsomere 2, metatarsomeres 3 and 4 as long as metatarsomere 2, metatarsomere 5 longer than metatarsomere 1.

ABDOMEN. Male: tergites with low-density randomly distributed micropunctuation. Posterior margin of tergite and sternite VII straight ( Fig. 6B–C View Fig ). Posterior margin of tergite VIII trilobed, with slightly triangular central lobe, lateral lobes less developed ( Fig. 6D View Fig ). Posterior margin of sternite VIII with midlongitudinal U-shape emargination; 2 lobes delimiting emargination with row of 5 dark setae; lateral angles slightly elevated ( Fig. 6E View Fig ). Posterior margin of tergite IX with midlongitudinal deep emargination in ½ of segment length; aedeagus, in parameral view, median lobe of uniform width along sides, slightly narrowing at base; apex with median emargination with elevated thinner disrupted edges laterally. pPMS of complex form, quadrate, flattened, shorter than APS. pLS not visible. APS spoon-like, flat, protruding upwards, with apex divided into 2 oval lobes ( Fig. 6F–I View Fig ). Female: unknown.

Distribution

This species is known only from the type locality in French Guiana (Saint-Laurent-du-Maroni, Saül, Mont Galbao). It was collected at a higher altitude, 740 m a.s.l., by a flight interception trap.
