( Fig. 13 )

Description. Male. Form subelongated, moderate-sized, integument piceous, clothed with dark brown, yellow, and gray pubescence. Head with a pair of yellowish, posteriorly divergent vittae on vertex between eyes. Antennae mostly covered with black pubescence, antennomeres III, IV, VI, VIII, and X with the basal third to half covered with white pubescence. Pronotum with three longitudinal parallel yellowish lines, the two outer lines connected behind. Scutellum piceous, with a minute patch of yellowish pubescence in the middle of the base. Elytra with three large patches of dark-brown pubescence, the anterior lateral, elongated, from the humeri almost reaching the middle; the second one rounded and post-median, equidistant from the outer margin and suture; and the third subquadrate in the apical fourth. Areas between the dark patches covered with sparse yellowish pubescence, denser on the margins of the obscure patches. The extreme apex with a transverse nitid white line. Legs with a ring of white pubescence in the middle of the meso- and metatibiae; the basal metarsomere covered with dense white pubescence. Sides of the metasternum and of the five basal ventrites covered with white pubescence.

Antennae exceeding elytral apices by 6 segments, segments 3 – 10 gradually decreasing in length, segment 11 longer than segment 10. Sides of the prothorax slightly divergent posteriorlybackwards, without tubercles or callosities on the posterior margin. Pronotum with a line of punctures on the posterior border. Prosternum with intercoxal process broad, as wide as one coxa; mesosternal process as wide as one coxa. Elytra with humeri sharply oblique and a minute shiny black tubercle on the posterior border. Apices slightly emarginatetruncate, inner angle dentate, outer angle produced in an acute spine, punctures sparse on the entire surface, denser in the basal third. Urotergite 5 with apex emarginate-truncate; urosternite 5 black and shiny, apex deeply emarginate. Protarsi fringed on the sides with long sparse hairs.

Female. Antennae exceeding elytral apices by 5 segments. Urotergite 5 slightly projected beyond the elytral apices, apex emarginate. Urosternite 5 black and shiny, apex semicircularly emarginate. Protarsi without hairs on lateral margins.

Measurements (mm), male/female. Total length, 9.5 – 13.3/9.3 – 11.5; prothorax length, 2.,0 – 2.5/1.7 – 2.0; prothorax width, 2.3 – 3.5/2.3 – 3.0; elytral length, 6.7 – 9.5/6.5 – 8.,5; humeral width, 3.,0 – 3.8/2.8 – 34.

Etymology. The species is named after Dr. Amy Berkov (AMNH), in recognition of her valuable research on the Cerambycidae of Lecythidaceae .

Comments. C. berkovi Monné & Monné sp. nov. has a similar pattern of coloration to C. meleagrina , but differs by the sides of the prothorax diverging posteriorly. In C. meleagrina the sides of the prothorax are rounded.
