Nyssodrysternum flavoguttatum sp. nov.

( Fig. 15 )

Etymology: Latin, flavo = yellow plus guttatum = speckled, spotted, in reference to the dorsal pubescence.

Male: Integument black. Pubescence predominantly dark brown to black. Yellow pubescence as follows: head, pronotum with two longitudinal stripes each side of the middle the inner with irregular borders, a dark brown area with two or four rounded spots, limited by the longitudinal stripes, and scutellum. Elytra densely covered with rounded yellow spots, more or less agglomerate and surrounding irregular dark brown spots. Basal fourth of the antennomeres III-VII, a median ring in the tibiae and the first two tarsomeres covered with grayish white pubescence.

Antennae attaining the apices of the elytra in the distal apex of the antennomere V. Sides of the prothorax with subacute tubercle in the beginning of the posterior fourth. Pronotum with a single row of punctures parallel to the posterior border. Apices of the elytra obliquely truncate, external angle acute, but not projected. Punctures scattered in the basal half. Fifth urotergite and urosternite subrounded in the apex. Metatarsome I one and a half longer than II+III.

Female: Antennae attaining the apices of the elytra in the middle of antennomere VI; fifth urotergite rounded in the apex; fifth urosternite subtruncate in the distal extremity.

Measurements (mm), male/female: Total length, 5,5-6,0/6,7-7,7; prothorax length, 1,0-1,1/1,2-1,5; prothorax width, 1,5-1,6/2,0-2,2; elytral length, 3,8-4,1/4,6-5,5; humeral width, 1,7-1,9/2,3-2,7.

Comments: The almost uniform yellow pubescence of N. flavoguttatum sp. nov. is exclusive of the new species, and allow us to identify.
