Differential diagnosis

Nyctonympha birai sp. nov. differs from N. annulata Aurivillius, 1990 by: the wider body; prothorax without lateral tubercles, as wide as long; elytral apex slightly projected at outer angle, and slightly obliquely truncate. In N. annulata ( Fig. 16 ), the body is slender, the prothorax is longer than wide, and the elytral apex has a long spine at outer angle and is strongly obliquely truncate.

Etymology

The specific epithet refers to the late Ubirajara Ribeiro Martins de Souza (Bira).

Description

Dimensions (mm). Holotype female/ paratypes male / paratypes female. Total length: 10.55/ 7.6– 8.4/7.90–9.65; prothoracic length: 1.85 /1.3–1.4/ 1.35–1.65; anterior prothoracic width: 1.65 /1.2– 1.3/1.20–1.50; posterior prothoracic width: 1.80 /1.1–1.2/1.25–1.60; widest prothoracic width (between apices of lateral tubercles): 2.10 /1.3–1.4/1.55–1.85; humeral width: 2.45 /1.7–1.8/ 1.75–2.15; elytral length: 7.90 / 5.7–6.3/5.95–7.40.

Female

Head dark-brown, reddish-brown on some areas; mouthparts reddish-brown; scape dark-brown, maculate with reddish-brown on some areas; antennomere III reddish-brown on base, gradually darkbrown toward apex; antennomeres IV–VII yellowish on basal half, gradually dark-brown toward apex; antennomeres VIII–XI yellowish on basal ⅔, dark-brown on distal third; prothorax dark reddish-brown, slightly lighter on some areas; ventral side of meso- and metathorax and abdomen dark-brown (reddishbrown on ventrite V); elytra pale reddish-brown, slightly darkened close to apex; femora reddish-brown, more brownish on some areas; tibiae dark reddish-brown on basal half, dark-brown on distal half. Pubescence grayish-white, not obscuring integument.

HEAD. Frons moderately coarsely, sparsely punctate (punctures slightly denser toward antennal tubercles); with some long, erect, yellowish setae close to lower eye lobes. Area between antennal tubercles with punctures as on frons, more abundant laterally. Area between upper eye lobes coarsely, abundantly punctate (punctures coarser than on frons). Remaining surface of vertex moderately coarsely (punctures slightly finer than on area between upper eye lobes), sparsely punctate (sparser centrally toward prothorax). Tempora moderately coarsely, sparsely punctate behind upper eye lobes (punctures as on area of vertex closer to prothorax); area behind lower eye lobe tumid close to eye, with row of moderately coarse punctures. Genae impunctate, with some long, erect, yellowish setae ventrally. Antennal tubercles impunctate. Coronal suture distinct from clypeus to prothoracic margin. Postclypeus glabrous laterally, with one long, erect, yellowish seta near glabrous area. Labrum concave, coplanar with anteclypeus on basal half, sloped on distal half; finely, abundantly punctate, mainly on coplanar region; with long, yellowish setae directed forward, mainly on sloped area. Mandibles with triangular depression on basal third; with long, sparse, erect, yellowish setae on basal half, glabrous on distal half. Distance between upper eye lobes 0.5 times length of scape; distance between lower eye lobes in frontal view equal to length of scape. Antennae 1.65 times elytral length, reaching elytral apex at basal quarter of antennomere IX; scape gradually enlarged on basal half (mainly at inner side), slightly narrowed toward apex on inner side of distal half; 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 = 0.78; pedicel = 0.14; IV = 1.72; V = 1.33; VI = 1.10; VII = 0.91; VIII = 0.76; IX = 0.71; X = 0.62; XI = 0.58.

THORAX. Prothorax, excluding lateral tubercles, as long as wide; sides with small, conical tubercle slightly before middle, with blunt apex; surface coarsely, moderately sparsely punctate. Pronotum centrally with gibbosity slightly elevated on base, followed by slightly elevated carina; surface coarsely, abundantly punctate. Prosternum coarsely, sparsely punctate. Mesosternum, mesepisternum and metepisternum impunctate. Metasternum coarsely, moderately sparsely punctate, mainly toward center. Scutellum centrally depressed and glabrous.

ELYTRA. Coarsely, abundantly punctate on basal half (punctures aligned in rows), distinctly sparser on distal half, mainly toward suture; apex slightly obliquely truncate (slightly concave), with outer angle forming short tooth.

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

ABDOMEN. Ventrites impunctate.

Variability

Antennomere III dark reddish-brown on basal ⅔, dark-brown on distal third; antennomeres IV–XI yellowish, abruptly dark-brown near apex; prothorax brown, dark-reddish brown on some areas.
