( Figures 1 a-d) Description . Female . Length 10.2-11.8 mm (measured from vertex to elytral apices), width 4.3-5.3 mm (measured across humeri). Habitus as in Fig. 1a . General form elongate-oblong, moderate-sized. Integument ferrugineous, with portions of scutellum, apical 1/3 of elytra, and tibial apices with dark brown or black pubescence; portions of pronotum and elytra with ochraceous, dark brown, black, and white pubescence. Head with frons roughly subquadrate, about 5 times width of lower eye lobe (as in Fig. 1c ). Eyes with lower lobes small, ovate-oblong; narrowest area connecting upper and lower eye lobes about 1-2 ommatidia wide. Genae elongate, a little taller than lower eye lobes. Antennae slightly longer than body; antennal tubercles prominent, moderately separated; tubercles armed at apex with short blunt tooth; scape robust, clavate, a little shorter than antennomere III, about as long as IV; antennomere III strongly sinuate; antennomeres IV-XI becoming progressively shorter; basal 1/2 of III-X with distinctly lighter pubescence. Figure 1. Hesycha tavakiliani , sp. nov. a) Dorsal habitus, holotype female. b) Lateral habitus, holotype female. c) Close-up of head, paratype female. d) Close-up of pronotum, holotype female. Pronotum slightly conical, slightly wider at base, transverse, about 1.3 times as wide as long, sides irregular, with a small, acute protuberance each side behind middle ( Fig. 1d ); disk with three moderately elevated tubercles, median tubercle oval, lateral tubercles reniform and more prominent; disk with 4 coarse punctures at basal transverse sulcus. Scutellum transverse, apex rounded. Elytra about 1.75 times as long as width at humeri ( Fig. 1a ), about 4 times as long as pronotal length, about 1.5 times broader basally than pronotum at widest (at base); lateral margins nearly straight, distinctly attenuate to apices, elytral apices obliquely truncate; base of each elytron with a feeble, broad gibbosity; basal 1/3 of elytra with moderate punctation, surface coarsely punctate; humeri prominent, anterior margin arcuate, angle with an obtuse tubercle. Venter with procoxae large, globose, not uncate; narrowest area of prosternal process between procoxae about 1/4 as wide as procoxal cavity; apex of prosternal process subtriangular. Mesosternal process about as wide as mesocoxal cavity; mesosternal process subtruncate-rounded. Fifth sternite about 1.5 times as long as IV, with a median triangular impression. Legs moderate in length; profemora robust; meso- and metafemora clavate apically; tibiae expanded apically; metafemora about 1/3 as long as elytra. Male . Unknown. Type Material . Holotype , female ( Fig. 1 a-b, d), “Pedra Azul, 700 m , M. Gerais , Brasil , XI .972, Seabra & Oliveira; Coleção Fragoso” ( MNRJ ). One paratype , female, same data as holotype ( MNRJ ). Etymology . We are pleased to name this species in honor of Gérard L. Tavakilian, for his collaboration and many contributions to the study of Neotropical Cerambycidae . The epithet is a noun in the genitive case. Diagnosis and Remarks . This species is distinguished from its congeners by the following characters: pronotum with a small, acute protuberance each side behind middle; scutellum with dark brown pubescence and longitudinal, ochraceous line at center; and apical 1/3 of elytra with distinct dark brown and white pubescence. This species is described from two female specimens, males are unknown. Nothing is known about the habitat and behavior of this species; however, both known specimens were collected at 700 m elevation.
