Nyssodrysternum proximum sp. nov.

( Fig. 9 )

Etymology: Latin, proximus mean nearest, by the similar pattern of coloration with N. serpentinum (Erichson, 1847) .

Male: Integument dark brown. Pubescence predominantly clear brown. Pubescence dark brown as follows: a lateral patch each side of the posterior margin of the pronotum; sides of the scutellum; in the elytra, a large oblique stripe from the umeri to the anterior border of a median white patch, a triangular patch in the posterior margin of the same white patch and a minute mark in the apical fourth of the elytra. The white pubescence covers the center of the scutellum, and in the elytra a large median lateral and punctured patch and a minute inverted “u” dot in the anterior margin of the apical brown patch. Ventral face of the body and legs covered with dense clear-brown pubescence.

Antennae reaching the apices of the elytra in the distal extremity of antennomere V. Prothorax with a minute lateral tubercle in the beginning of the posterior third. Pronotum with a line of punctures parallel to the anterior and posterior margins. Apices of the elytra obliquely truncate, each angle with a minute spine. Elytral surface with dense punctures in the basal half, the distal half without punctures. Fifth urotergite and urosternite semicircularly emarginate in the distal extremity. Metatarsome I as long as II+III.

Female: Antennae reaching the apices of the elytra in the apex of antennomere VI; fifth urotergite subrounded in the distal extremity, fifth urosternite transversely truncate at apex.

Measurements (mm), male/female: Total length, 6,5/7,7-8,8; prothorax length, 1,3/1,5-1,9; prothorax width, 1,8/2,1-2,5; elytral length, 4,5/5,5-6,5; humeral width, 2,2/2,6-3,1.

Comments: Very similar in pattern of coloration with N. serpentinum (Erichson, 1847) ; differs mainly by the median lateral white patch of the elytra, bordered anterior and posteriorly by dark brown pubescence, also the apex of the fifth urotergite in the female of N. proximum sp. nov. is clearly subrounded. In N. serpentinum the median lateral white patch of the elytra is not bordered by dark brown pubescence and the distal extremity of the fifth urotergite in the female is acute.
