Hesychotypa danileuskyi Nearns and Nascimento , sp. nov.

( Figures 1 a–d)

Description. Male. Length 13.65 mm (measured from vertex to elytral apices), width 4.95 mm (measured across humeri). Habitus as in Fig. 1a . Integument mostly black; distal area of postclypeus yellowishbrown; distal area of labrum reddish-brown; apex of last labial and maxillary palpomeres reddish-brown; antennomeres gradually dark brown toward antennomere XI.

Head. Frons slightly elongate, finely, sparsely punctate (punctures more abundant near clypeus); with abundant yellowish-brown pubescence not obscuring integument. Vertex impunctate; with longitudinal brownish-green pubescent band on each side of median groove, surrounded by light yellowish-brown pubescence; area close to upper eye lobes narrowly glabrous. Area behind eye lobes with yellowishgreen pubescence interspersed with light yellowish-brown pubescence, not obscuring integument, more uniformly yellowish-brown toward apex of lower eye lobes (narrowly denser close to lower eye lobe). Antennal tubercles elevate, not horn-shaped; pubescence as on frons. Median groove distinct from clypeus to prothoracic margin. Genae slightly longer than half of length of lower eye lobe; with yellowish-brown pubescence, very sparse toward dorsal side, denser, not obscuring integument, toward ventral side. Distance between upper eye lobes 0.37 times length of scape; in frontal view, distance between lower eye lobes 0.75 times length of scape. Antennae 2.3 times elytral length, reaching elytral apex at middle of antennomere VI; scape with yellowish-brown pubescence partially obscuring integument; pedicel with grayish-white pubescence interspersed with yellowish-brown pubescence; antennomeres III–IV with grayish-white pubescence basally (this area shorter on III), and yellowish-brown pubescence on remaining surface; remaining antennomeres with grayish-white pubescence covering from basal third to basal half, and yellowish-brown pubescence toward apex; antennomeres III–V with erect, dark setae ventrally (shorter, sparser toward V); antennomere III straight; antennal formula based on antennomere III: scape = 0.56; II = 0.10; IV = 0.83; V = 0.59; VI = 0.49; VII = 0.42; VIII = 0.41; IX = 0.40; X = 0.39; XI = 0.37.

Thorax. Prothorax wider at base, transverse, 1.65 times as wide as long, sides with tubercle from about basal third to near midlength, with apex of tubercle conical and blunt. Pronotum with basal and distal sulci distinct; coarsely punctate on base of lateral gibbosities, smooth on remaining surface; with three wide brownish-green pubescent bands, one longitudinal, irregular on each side, another Y-shaped centrally; remaining surface with light yellowish-brown pubescence, more yellowish-white on sides of basal half. Sides of prothorax coarsely, sparsely punctate in basal half; with pubescence mostly brownish-green centrally, mostly light yellowish-brown on remaining surface. Prosternum and mesoventrite with light yellowish-brown pubescence, denser laterally. Prosternal process triangularly widened from near base to apex; with sparse light yellowish-brown pubescence. Mesepisternum centrally with brownish-green pubescence surrounded with light yellowish-brown pubescence. Mesosternal process with distal margin slightly concave, slightly narrower than mesocoxal cavity. Metepisternum and metasternum with light yellowish-brown pubescence partially obscuring integument. Scutellum with brownish-green pubescence in wide central area, and yellowish-white pubescence laterally.

Elytra. Slightly shorter than twice humeral width, 4.1 times as long as prothoracic length; parallel-sided at basal 2/3, uniformly rounded toward suture at distal third; finely, moderately abundantly punctate in basal third, punctures gradually sparser toward apex; humerus forming obtuse tubercle; pubescence mostly brownish-green except following light yellowish-brown pubescent maculae interspersed with yellowish-white pubescence: three small close to basal curvature; small, sparse, nearly circular in basal third, and another elongate close to suture; four longitudinal, partially fused, about central third, outermost placed close to epipleura, innermost placed about center of dorsal surface, gradually shorter from outermost to innermost, together forming wide, oblique band; irregular, mostly longitudinal, partially fused in distal third (covering most of surface of distal third). Legs. Femora with brownish-green pubescence interspersed with yellowish-brown pubescence (the latter forming irregular distal ring). Tibiae with pubescence mostly as on femora, but with golden pubescence in some areas, especially distally. Metatarsomere I 0.65 times II–III together.

Abdomen. Ventrites with yellowish-brown pubescence partially obscuring integument; apex of ventrite V truncate.

Female. Unknown.

Type material. Holotype ( Fig. 1 a–d) male from PANAMA, Panama: Soberanía National Park (Pipeline road at 2.3 km; beating plants / at Hg/UV lights), 18.V.2013, N. Franz col. ( NMNH).

Etymology. The new species is named in honor of Mikhail Leontievich Danilevsky (Russian Academy of Sciences, Moscow, Russia) for his many contributions to the study of Cerambycidae . The epithet is a noun in the genitive case.

Diagnosis and remarks. This species differs from males of species with similar general appearance as follows (only the most notable characters are used): from H. ableptema Martins and Galileo, 1990 , H. jaspidea (Bates, 1865) and H. subfasciata Dillon and Dillon, 1945 by the antennal tubercles not horn-shaped and antennomere III straight (respectively, horn-shaped, and sinuous in these species); from H. aeropa Dillon and Dillon, 1945 , H. fernandezi Martins and Galileo, 1999 and H. lirissa Dillon and Dillon, 1945 by the antennal tubercles not horn-shaped and lower eye lobes distinctly longer than gena (respectively, horn-shaped, and about as long as gena in these species); from H. liturata (Bates, 1865) by the antennomere III straight and elytral apex rounded (respectively, sinuous, and obliquely truncate in H. liturata ); and from H. heraldica (Bates, 1872) by the antennomere III straight, shorter antennae reaching elytral apex at middle of antennomere VI, and antennomere XI distinctly shorter than IV (respectively, sinuous, reaching elytral apex at about apex of antennomere V, and slightly shorter than IV in H. heraldica ).
