Differential diagnosis

Nyctonympha antonkozlovi sp. nov. differs from N. boyacana Martins & Galileo, 2008 (see photograph of the holotype in Bezark 2016) by: the scape, pronotum and elytra distinctly less punctate (mainly scape); femora without punctures surrounded by glabrous area; mesepisternum impunctate. In N. boyacana the scape, pronotum and elytra are distinctly more densely punctate, the femora have punctures surrounded by glabrous areas, and the mesepisternum is punctate. The new species differs from N. howdenarum Martins & Galileo, 1992 by the wider body, by the distance between upper eye lobes distinctly wider than width of one lobe, by the prothorax wider than long, and by the pronotum with gibbosities. In N. howdenarum the body is slender, the distance between upper eye lobes is about equal to width of one lobe, the prothorax is about as long as wide (including lateral tubercles), and the pronotum has no gibbosities.

Etymology

The specific epithet refers to Anton Olegovich Kozlov, who sent and donated the holotype.

Type material

Holotype

COLOMBIA: ♂, Quindio, Calarcá (border to Tolima Department), 04º28′28″ N, 75º33′30″ W, 3290 m, 23–24 Mar. 2015, V. Sinjaev leg. ( MZSP).

Description

Dimensions (mm). Total length: 15.10; prothoracic length: 2.10; anterior prothoracic width: 2.05; posterior prothoracic width: 2.40; widest prothoracic width (between apices of lateral tubercles): 2.65; humeral width: 3.50; elytral length: 11.80.

Male

Integument dark-brown; mouthparts reddish-brown except palpi brown with only basal and distal areas reddish-brown; antennomeres V–XI yellowish ringed on base; antennomeres gradually lighter toward distal segments, mainly after VIII; gula yellowish-brown on base, gradually dark-brown toward submentum; distal area of ventrites I–IV narrowly, transversely reddish-brown.

HEAD. Frons finely, sparsely punctate ( Fig. 5 ), mainly toward clypeus; with short, decumbent, ochraceous setae, distinctly not obscuring integument, sparser toward clypeus, mainly laterally; with some long, erect, yellowish setae close to eyes. With narrow band of yellowish setae surrounding eyes.Area between antennal tubercles finely, sparsely punctate, mainly toward center; with short, decumbent, moderately sparse, ochraceous setae. Remaining surface of vertex finely, abundantly punctate; with short, abundant, yellowish setae, partially obscuring integument (distinctly longer than on frons); with some long, erect, yellowish setae close to eyes. Tempora with short, abundant, yellowish setae, interspersed with some long, erect, yellowish setae near lower eye lobes (area closer to prothorax glabrous behind lower eye lobes). Genae with short, decumbent, ochraceous setae toward apex (distinctly shorter and finer than yellowish band), sparser toward dorsal side. Antennal tubercles finely, sparsely punctate on base; with ochraceous pubescence on base, gradually yellowish toward apex. Coronal suture slightly distinct from clypeus to middle of frons, distinct from this area to prothoracic margin. Postclypeus with short, sparse, ochraceous setae except glabrous lateral area. Labrum concave, coplanar with anteclypeus on basal half, sloped on distal half; finely, sparsely punctate on base of coplanar area, denser about middle, sparser toward apex; with moderately sparse, ochraceous setae, interspersed with long, erect, yellowish setae mainly laterally after middle. Mandibles with triangular depression on basal half; with short, abundant, yellowish setae inside depression, glabrous on remaining surface. Distance between upper eye lobes 0.45 times length of scape; distance between lower eye lobes in frontal view 0.90 times length of scape. Antennae 1.6 times elytral length, reaching elytral apex at basal quarter of antennomere IX; antennal segments with ochraceous pubescence, not obscuring integument; scape gradually enlarged toward base of distal third, then slightly narrowed toward apex, with long, erect, yellowish setae ventrally near apex; antennomeres III–XI with moderately long, erect, yellowish setae ventrally, gradually shorter and sparser toward distal segments; antennal formula (ratio) based on antennomere III: scape = 1.15; pedicel = 0.22; IV = 2.70; V = 2.00; VI = 1.74; VII = 1.59; VIII = 1.29; IX = 1.27; X = 1.18; XI = 1.18.

THORAX. Prothorax wider than long (1.2 times); sides concave between base and lateral tubercle and slightly concave between lateral tubercle and distal margin; finely, sparsely punctate below lateral tubercle, gradually sparser centrally toward ventral side, densely basally toward prosternal process; with ochraceous pubescence, partially obscuring integument, distinctly sparser basally. Pronotum transversely sulcate near base and apex (less so centrally); sides with conical, moderately acute tubercle placed about middle; with three distinct gibbosities: one at each side of anterior half, close to middle of pronotum, transverse, slightly oblique, and one centrally, elongate, more elevated than lateral gibbosities, narrowed toward distal area of pronotum; surface finely, moderately abundantly punctate (punctures slightly coarser than on sides of prothorax), smooth on part of central gibbosity; with ochraceous pubescence, partially obscuring integument, except glabrous top of central gibbosity. Prosternum finely, moderately abundantly punctate (punctures as on sides of prothorax); with ochraceous pubescence, partially obscuring integument. Prosternal process without distinct punctures; with ochraceous pubescence obscuring part of integument. Mesosternum depressed on wider central area; finely, sparsely punctate on depressed region, smooth laterally; with ochraceous pubescence not obscuring integument, more distinct laterally. Mesepisternum and mesepimeron impunctate; with ochraceous pubescence, partially obscuring integument. Mesosternal process deeply emarginate at apex, laterally forming acute lobe at each side. Metepisternum finely, sparsely punctate; with ochraceous pubescence partially obscuring integument. Metasternum coarsely, moderately abundantly punctate laterally; with ochraceous pubescence not obscuring integument (obscuring integument on area near metacoxae); with long, erect, sparse, yellowish setae. Scutellum slightly depressed centrally on basal ⅔, truncate at apex; with ochraceous pubescence not obscuring integument.

ELYTRA. Surface somewhat irregular; finely, moderately abundantly punctate on basal half, gradually sparser toward apex, interspersed with coarse punctures; with ochraceous, dense pubescence interspersed with several irregular areas with sparser pubescence; with erect, sparse, yellowish setae on distal quarter (longer, more abundant laterally and toward apex); apex obliquely truncate, with outer angle distinctly spined and sutural angle rounded.

LEGS. Femora with ochraceous pubescence, not obscuring integument; without punctures surrounded by glabrous areas.

ABDOMEN. Ventrites finely, moderately abundantly punctate laterally, gradually finer, sparser toward center; with ochraceous pubescence not obscuring integument, interspersed with long, erect, yellowish setae; apex of ventrite V rounded, centrally emarginate.
