Nyssodrysternum vanini sp. nov.

( Fig. 6 )

Etymology: The epithet is an acknowledgment to the colleague Dr. Sergio A. Vanin, ( MZSP), who collect one of the specimens.

Male: Integument dark brown. Pubescence predominantly dark brown. Pubescence gray-yellowish: head with a narrow line surrounding the eyes; pronotum with seven longitudinal stripes, the median one very narrow, the external broader. Elytron with a neat patch in the basal half, and four longitudinal lines, three of them visible from above and the external one in the epipleuron; distal half with five or six longitudinal stripes. Ventral face of the body and femora covered with grayish pubescence. Tibiae and tarsi dark brown.

Antennae two times the length of the body; attaining the apices of the elytra in the apex of antennomere V. Prothorax with a subconical lateral tubercle in the beginning of the posterior third. Pronotum with a single line of punctures parallel to the posterior margin. Elytra obliquely truncate, the external angle projected in acute spine. Punctures restricted to a few longitudinal lines in the basal half near the suture. Metatarsomere I slightly longer than II+III. Fifth urotergite subtruncate in the apex; fifth urosternite semicircularly emarginate, angles projected in acute spines.

Female: Antennae reaching the apices of the elytra in the base of antennomere VI. Ovipositor projected 1.0 mm beyond the elytral apices. Fifth urotergite acute in the apex; fifth urosternite subtruncate and densely pilose in the distal extremity.

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

Type material: Holotype male, BRAZIL, Rondônia: Ouro Preto do Oeste , X.1986, O. Roppa, P. Magno & J. Becker col. ( MNRJ) . Paratypes: same data of the holotype, female ( MNRJ) , female, VIII.1980, B. Silva col., female, XI.1983, O. Roppa, J. Becker & B. Silva col. ( MNRJ) . Guajará Mirim (36 km da Foz com o Rio Guaporé ), female, 16.IV.1976, S.A. Vanin col. ( MZSP) . Pará: Jacareacanga , female, IV.1969, F.R. Barbosa col. ( MNRJ) .

Comments: N. vanini sp. nov. is similar to N. rodens (Bates, 1864) , by the pattern of the elytral patches, but differs by the seven narrow longitudinal grayish lines in the pronotum and by the elytra acutely spinose in the apices. In N. rodens the lines of the pronotum are broadest and most part of them yellow, and the apices of the elytra are less produced in the external angle.
