Tuberolamia santossilvai sp. nov.

( Figs. 17–21 )

Description. Holotype male. Integument shiny, mostly black with some green metallic reflections on some areas (depending on light source); anteclypeus with small brown area laterally; basal half of femora, basal 3/4 of tibiae, tarsomeres I–II, and most of posterior quarter of elytra reddish brown. Pedicel and antennomeres III–XI orangish brown basally and light brown on the remaining surface.

Head. Frons elongate, finely punctate, except longitudinal row of coarse punctures laterally, each puncture with long, thick, erect black seta; surface with sparse, coarse brown pubescence, gradually more abundant toward antennal tubercles. Genae with sculpturing and pubescence as on frons except glabrous longitudinal band from lower eye lobe to near anteclypeus. Median groove distinctly marked on vertex, slightly marked on frons. Antennal tubercles elevated in frontal view, their inner margins V-shaped. Clypeus smooth, glabrous and impunctate. Labrum with coarse punctures and black pubescence with long, erect setae interspersed. Mandible with coarse punctures. Distance between upper eye lobes 1.65 times distance between an upper lobe. In frontal view, distance between lower eye lobes 2.85 times distance between widest width of a lower lobe. Antennae 1.45 times length of elytra, reaching elytral apex at apex of antennomere XIII. Scape subpiriform, with some coarse punctures; with dark-brown pubescence not obscuring integument, and erect setae interspersed. Pedicel with thick brown pubescence; with erect black setae ventrally. Antennomeres III–XI with sparse white pubescence on anterior quarter; remaining surface with brown pubescence not obscuring integument, pubescence gradually bristly toward apical antennomeres; with long, erect, thick black setae ventrally. Antennal formula based on length of antennomere III: scape = 0.93; pedicel = 0.14; IV = 0.97; V = 0.82; VI = 0.72; VII = 0.57; VIII = 0.48; IX = 0.47; X = 0.55; XI = 0.54.

Thorax. Prothorax 1.2 times wider than long, including lateral protuberances; glabrous, wrinkled transversely, except conspicuous, large, smooth area about middle; with long, thick, erect black setae. Sides of prothorax wrinkled transversely. Prosternum with moderately sparse white pubescence. Prosternal process with moderately abundant white pubescence; distinctly narrowed centrally. Mesoventrite with white pubescence, gradually more abundant toward margins of mesocoxae, pubescence sparser on sides of wide anterior area. Metaventrite with white pubescence. Scutellum 2.74 times longer than wide, broadly rounded apically, with black pubescence not obscuring integument. Elytra. Humeri not protruding; with dense, veined sculpture on basal quarter, asperate on remaining surface; apex individually subacute; with sparse dark-yellow pubescence, thick, denser on some areas centrally and apically; with dense, irregular white pubescent maculae centrally; with long, erect black setae interspersed; with large, raised, blunt-tipped tubercle on anterior third, located closer to side than to suture. Legs. Pro- and mesofemora subfusiform, metafemora more elongated, slightly exceeding elytral apex, with short white pubescence not obscuring integument, gradually more abundant toward base, with a few black erect setae interspersed. Tibiae with short white pubescence from base to apical third; remaining surface with abundant, bristly black pubescence partially obscuring integument; with long, erect black setae interspersed. Metatarsomere I longer than II–III combined.

Abdomen. Ventrites smooth, with sparse, very short white pubescence clearly not obscuring integument; with long, erect setae interspersed. Ventrites gradually shorter from 1 to 4; ventrite 5 with abundant setae on apical margin and slightly longer than ventrite 4.

Dimensions (mm) Holotype male. Total length, 8.00; prothoracic length, 1.60; anterior prothoracic width, 1.90; posterior prothoracic width, 1.65; maximum prothoracic width, 2.10; humeral width, 2.15; elytral length, 5.00.

Type material. Holotype male from PERU. Huanuco: San Marcos , 9°54’11.1”S 76°06’01.7”W, 3115 m, 27.III.2010, W. Cosio leg. ( UNSAAC).

Etymology. This species is named in honor of Antonio Santos-Silva for his constant help, work, and commitment to the taxonomy of Cerambycidae .

Remarks Tuberolamia santossilvai sp. nov. differs from T. andicola Breuning 1940 and T. grilloides Touroult & Demez 2012 by the strongly veined anterior area of elytra (not so in T. andicola and T. grilloides ). It also differs from T. grilloides by the antennae distinctly shorter in male (much longer, about twice elytral length in males of T. grilloides ), and elytra with dense white pubescent maculae (absent in T. grilloides ); and from T. andicola by the black elytra (not black in T. andicola ).
