Diagnosis

Neolindus volkeri Guzman, Tokareva & Żyła sp. nov. resembles N. schubarti and N. irmleri in aedeagus morphology. However, in N. volkeri , the median invagination on the parameral side of the median lobe is wider than in the other two species ( Herman 1991: fig. 210; Asenjo 2011: fig. 2; Fig. 23F–G View Fig ). Unlike the two similar species, N. volkeri has a deep midline emargination with a convex median part on the posterior margin of sternite VII, with acute protruding processes on both sides (emargination shallow and without processes in both N. schubarti and N. irmleri ) ( Herman 1991; fig. 208; Asenjo 2011: fig. 4; Fig. 23C View Fig ). Additionally, the posterior margin of tergite VIII has deeper pair of emarginations surrounded by invaginated areas (shallower and without invagination in N. schubarti and N. irmleri ) ( Fig. 23D View Fig ; Herman 1991: fig. 206; Asenjo 2011: fig. 6).

Etymology

This species is dedicated to the great taxonomist, Volker Assing, who passed away prematurely. He was a renowned specialist in Palaearctic and Oriental Paederinae and described two species of Neolindus .

Neck with foramen magnum occupying ½ of occiput. Antenna thin and elongate, longer than head and pronotum combined, all antennomeres longer than wide, tomentose pubescence starting from antennomere 3, antennomere 1 as long as antennomere 2 and 3 combined, antennomere 3 longer than 2. Labrum tetralobed, central lobes well-developed, central emargination shallow, V-shaped, with 2 dark thick seta in median line of labrum lobes ( Fig. 23A View Fig ; Supp. file 2).

THORAX. Pronotum nearly quadrate, with umbilicate micropunctures and 2 distinct paramedial and lateral rows of setae. Basisternum of prosternum with 4 anterior setae and 1 posterior pair of setae. Metasternal intercoxal process with 1 pair of acute processes. Elytron longer than wide, surface of elytra with umbilicate micropunctures in 8–9 moderately dense longitudinal rows ( Fig. 23A View Fig ; Supp. file 2).

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

ABDOMEN. Tergites with low density, randomly placed micropunctures. Posterior margin of tergite VII straight ( Fig. 23B View Fig ).

Posterior margin of sternite VIII with shallow midlongitudinal emargination and rounded lateral angles ( Fig. 23E View Fig ). Posterior margin of tergite IX with midlongitudinal deep emargination about ¾ of segment length; aedeagus, median lobe robust, strongly sclerotised, medially widened, apex with 2 sclerotised processes, deep midpoint emargination reaching middle of lobe, edges of emargination with brush of 5–7 short, dark setae; pLS small, oval, hidden under APS; APS oval, spoon-shape, covering pLS and pPMS. pPMS of complicated form, with several lamellas and arms, anchored with sclerotised ring under membrane ( Fig. 23F–I View Fig ). Female: lack of emargination on posterior margin of sternite VII; posterior margion of tergite VIII slightly sinuated.

Distribution

The species is only known from the type locality in French Guiana, (Cayenne, Roura). It was collected at a low altitude using a flight interception trap.
