Type material

Holotype male. COLOMBIA, Bolívar : Santuario de Fauna y Flora Los Colorados (Villa Roca, 180 m, 9°54'N 75°9'W, 180 m), 22.iv–7.v.2001, E. Deulufeut, “Malaise,” IAvH-E-209972 ( IAVH).

Diagnosis

This species can be distinguished from other species in the genus by the pronotal tubercles; prothorax rounded, anteriorly and basally constricted; elytra light brown, coarsely punctate, sutural margin with toothed projection; femora slightly clavate.

Description

Male. Integument mostly brown; pronotum and head with dark brown areas; elytra and legs lighter brown.

Head. Frons and vertex coarsely, densely alveolate. Antennal tubercles distinctly elevated, acute at apex. Mandibles with long, sparse, golden setae on outer surface. Distance between upper eye lobes three times width of one upper eye lobe. Antennae reaching elytral apex at base of antennomere XI. Scape coarsely, densely, shallowly alveolate throughout; with long, sparse, golden setae. Antennal formula (ratio) based on length of antennomere III: scape = 0.97; pedicel = 0.23; IV = 1; V = 1; VI = 1; VII = 0.9; VIII = 0.74; IX = 0.77; X = 0.73; XI = 1.1.

Thorax. Prothorax about 1.2 times longer than largest width; anteriorly slightly constricted before margin; posteriorly distinctly constricted at posterior fifth. Pronotum coarsely alveolate, with median longitudinal sulcus, wider anteriorly; with long, randomly oriented, sparse, pale yellow setae at sides; with two small, barely evident, rounded tubercles on anterior half; and two prominent gibbosities in posterior half. Anterior half of prosternum with sparse punctures. Prosternal process flattened and expanded laterally at apex, width at narrowest point half of procoxal cavity width. Mesoventrite microsculptured, with coarse punctation laterally. Mesoventral process microsculptured, narrower than mesocoxal cavities, apex emarginate. Metanepisternum with sparse long setae. Metaventrite microsculptured; densely pubescent laterally; coarsely, shallowly punctate near mesocoxal cavities, with sparse fine punctures on remaining surface, except for smooth central area. Scutellum rounded at apex. Elytra coarsely, deeply, abundantly punctate; with five longitudinal rows of long setae on each elytron; apices emarginate with small, acute spine on outer margin and slightly dentate projection on sutural margin. Legs with tibiae distinctly carinate and flattened.

Abdomen. Ventrites with long and short setae; ventrite I about as long as ventrites II–III together; apex of ventrite V transverse and subrounded.

Measurements. Holotype, male, total length: 6.1 mm, prothorax length: 1.4 mm, prothorax width at widest point: 1.2 mm, elytral length: 4.1 mm, humeral width: 1.5 mm.

Etymology

The specific name is in honour of Claudia Martínez in recognition of her contributions to the knowledge of Colombian Cerambycidae and for her kind assistance to the second author when he first started his research on Cerambycidea.

Remarks

Hemilissa claudiae belongs to the group of species of the genera characterised by the tuberculate pronotum. These species are H. fabulosa Martins, 1985 , H. gummosa , and H. emblema Martins, 1976 . Hemilissa claudiae differs from H. fabulosa by the unicolorous elytra (in H. fabulosa the elytra have dark and white areas). The new species differs from H. gummosa by the prothorax rounded at sides, with anterior and basal constrictions, and the elytra without microsculpturing (in H. gummosa , the prothorax is subcylindrical, wider anteriorly, and the anterior half of the elytra is microsculptured). Hemilissa claudiae differs from H. emblema ( Figs. 23–25 ) by the lighter integument, smaller size (total length = 6.1 mm), elytra without microsculpture, and femora slightly clavate. In H. emblema , the integument is dark brown, the size is larger (total length = 10.3 mm – holotype measured), and the femora are strongly clavate.
