Differential diagnosis

Martins & Galileo (1989) discussed N. flavipes (translated): “Species very close to N. annulipes . The elytral apex in N. flavipes is unarmed or very slightly projected at sutural angle, and the outer spine is wide, relatively short; the femora and tibiae are yellowish with a central brownish ring. That same color was mentioned by Belon (1897) in the description of N. annulipes . The identification of Belon’s species was only possible via the examination of two syntypes (besides 15 other syntypes not examined, MNHN). The designation of the lectotype for N. annulipes would be very desirable because, perhaps, the type series is a composite.” Nyctonympha mariahelenae sp. nov. differs from N. flavipes as follows: body wider; prothorax as wide as long; elytral punctures finer, less dense, mainly on distal half near suture; elytral apex less obliquely truncate, with outer angle shorter. In N. flavipes ( Fig. 20 ) the body is slender, the prothorax (without lateral tubercles) is longer than wide, the elytral punctures are coarse, more abundant, including on distal half near suture, and the elytral apex is distinctly more oblique, with the spine of outer angle distinctly longer.

Etymology

The specific epithet refers to Maria Helena M. Galileo for her contribution to our knowledge of Cerambycidae from the Neotropical region.

Part of grayish-white pubescence more yellowish depending on angle of light.

HEAD. Frons moderately coarsely, abundantly punctate; with grayish-white pubescence not obscuring integument; with one long, erect, yellowish seta close to lower eye lobes. Vertex moderately finely, abundantly punctate (punctures denser than on frons); with grayish pubescence not obscuring integument. Eyes surrounded by narrow band of yellowish pubescence. Tempora with punctures as on vertex on area closer to vertex, impunctate on remaining surface behind upper eye lobe, tumid, finely, sparsely punctate close to lower eye lobe; with grayish-white pubescence behind upper eye lobes and tumid area behind lower eye lobes (except yellowish band close to eye), glabrous on remaining surface behind lower eye lobes. Genae finely striate centrally; with sparse, grayish-white pubescence, gradually sparser toward apex; with some long, erect, yellowish setae ventrally. Antennal tubercles impunctate; with grayishwhite pubescence not obscuring integument. Coronal suture distinct from clypeus to prothoracic margin. Postclypeus very narrow, shiny, with a central longitudinal carina. Labrum concave, coplanar with anteclypeus on basal quarter, distinctly sloped on distal ¾; finely, abundantly punctate; with long, erect, yellowish setae directed forward, mainly laterally. Mandibles with wide, sub-triangular depression from base to slightly after middle; with long, sparse, erect, yellowish setae on sub-triangular depression, glabrous toward apex. Distance between upper eye lobes 0.3 times length of scape; distance between lower eye lobes in frontal view 0.8 times length of scape. Antennae 1.75 times elytral length, reaching elytral apex at distal third of antennomere VIII; scape gradually enlarged on basal third (more abruptly at inner side); ventral side of scape, pedicel and antennomeres with erect, brownish setae ventrally, more abundant on III, gradually shorter, sparser toward distal segments; antennal formula (ratio) based on antennomere III: scape = 0.88; pedicel = 0.15; IV = 1.67; V = 1.49; VI = 1.20; VII = 1.00; VIII = 0.84; IX = 0.75; X = 0.71; XI = 0.82.

THORAX. Prothorax, excluding lateral tubercles, as long as wide; sides with small, conical tubercle at middle; surface moderately fine, abundantly punctate; with grayish-white pubescence not obscuring integument. Pronotum almost impunctate basally, centrally longitudinally carinate; remaining surface coarsely, abundantly, partially confluently punctate; surface with grayish-white pubescence, not obscuring integument, except on center of longitudinal carina with yellowish pubescence. Prosternum moderately finely, sparsely punctate; with grayish-white pubescence not obscuring integument. Mesosternum centrally finely, moderately abundant punctate, smooth laterally; with grayish-white pubescence more distinct and abundant laterally. Mesepisternum moderately coarsely, abundantly punctate; with slightly yellowish pubescence not obscuring integument. Metepisternum with slightly yellowish pubescence not obscuring integument. Metasternum moderately coarsely, sparsely punctate; with yellowish pubescence not obscuring integument. Scutellum with grayish-white pubescence, more yellowish laterally.

ELYTRA. Coarsely, abundantly punctate, distinctly sparser near suture on distal third and laterally on distal quarter; with several irregular, small areas with grayish pubescence distinctly contrasting with the

general pubescence; apex obliquely sinuous, with outer angle forming distinct tooth and sutural angle rounded, slightly projected.

LEGS. Meso- and metatibiae with moderately short, erect, abundant, yellowish setae on distal third.

ABDOMEN. Ventrites impunctate; with grayish-white pubescence interspersed with long, erect, sparse setae (more abundant on distal half of ventrite V); ventrite V slightly sulcate longitudinally at center on basal ¾, with apex truncate.

Male

Antennae longer, reaching elytral apex at base of distal third of antennomere VI. Apex of ventrite V slightly and widely emarginate.

Variability

Antennomere III dark reddish-brown on basal ¾; antennomere X brownish only near apex; antennomere XI yellowish with slightly distinct brownish ring near apex; tarsomeres maculate with brown color; punctures on frons denser, similar to vertex; pronotum punctate basally; pronotal punctures not partially confluent.

Remarks

Nyctonympha flavipes was recorded from Peru and Brazil (Rondônia) by Martins & Galileo (1989) and for Brazil (Maranhão) by Martins et al. (2011). However, as N. flavipes was mistakenly identified, we are formally excluding this species from the Peruvian and Brazilian fauna.
