Nyssodrysternum gilvolineatum sp. nov.

( Fig. 1 )

Etymology: Latin, gilvus, pale-yellow plus linea, line.

Male: Integument dark brown. Pubescence predominantly dark brown. Pubescence yellowish as follows: head, two longitudinal stripes each side of the middle, in the elytra a comma-like spot each side of the scutellum and in the basal half four longitudinal stripes, partially grayish and other three similar stripes in the apical half. Three longitudinal grayish stripes in the pronotum, one in the middle and other each side of the middle between the yellow stripes. Underside of the body and legs (except tarsi dark brown), covered with grayish pubescence.

Antennae very long, three times the length of the body, extending beyond apices of the elytra by 6 antennomeres, antennomere XI one third longer than X. Lateral tubercle of the prothorax minute; a single line of punctures near the posterior border of the pronotum. Elytral apices obliquely emarginate, external angle projected in a minute spine. Elytral surface with dense punctures restricted to a line parallel to the suture in the basal half and with scattered punctures in the sides.

Metatarsomere I more than twice II+III. Fifth urotergite triangularly emarginate in the apex; fifth urosternite semicircularly emarginate and densely pilose in the distal extremity.

Female: Antennae attaining the apices of the elytra in the middle of antennomere VI; ovipositor projected 2.0 mm beyond the elytral apices; fifith urotergite subrounded in the apex, fifth urosternite shallowly semicircularly emarginate in the distal extremity.

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

Comments. The Amazonian species of Nyssodrysternum with yellow longitudinal lines of pubescence in the elytra are N. flavolineatum Monné, 1985 , N. promeces (Bates, 1864) N. taeniatus Monné, 1985 and N. gilvolineatum sp. nov. The three first species differs from N. gilvolineatum sp. nov. by the elytra with entire longitudinal yellow lines, from base to apex, in the new species the longitudinal lines are interrupted medially by patches of brown pubescence.
