Nyssodrysternum insulorum sp. nov.

( Fig. 12 )

Etymology: The epiteth is a reference to Barro Colorado Island, where most part of the specimens were collected.

Male: Integument dark brown to black, Pubescence predominantly dark brown. Pubescence grayish-brown: head (except a brown line behind the superior lobes of the eyes), basal fifth of the antennomeres III-VII. Pronotum with a large patch each side of the middle that encircle a longitudinal dark brown stripe, in the anterior and posterior border of the middle of the pronotum a spot of grayish-brown pubescence. The whole surface of the elytra covered with rounded and subrounded grayish brown spots, more os less disposed in transversal strpes in the base, the middle and the apical fourth.

Antennae attaining the apices of the elytra in the distal extremity of antennomere V. Prothorax with a subacute lateral tubercle in the beginning of the posterior third. Pronotum with a single row of punctures parallel to the posterior border. Elitral apices semicircularly emarginate, sutural angle projected in obtuse tooth, the marginal angle projected in a short acute spine. Large punctures disposed in a few longitudinal lines in the anterior half of the elytra Fifth urotergite and urosternite shallowly emarginate in the apex. Procoxae, mesocoxae, metacoxae, center of the mesosternum, metasternum and median region of the urosternites covered with dense appressed golden pubescence. Protarsi with long and dense hairs in the lateral margins. Metatarsomere I a little shorter than II+III.

Female: Ovipositor projected near 1,0 mm beyond the elytral apices; fifth urotergite subtruncate, fifth urosternite acute in the distal extremity, ventral surface without golden pubescence, protarsi without dense lateral hairs.

Measurements (mm), male/female: Total length, 9,0-10,0/8,3-9,0; prothorax length, 1,8-2,1/1,4/1,5; prothorax width, 2,7-2,8/2,3-2,3; elytral length, 6,4-7,0/5,8-6,3; humeral width, 3,1-3,2/2,8-3,0.

Type material: Holotype male, PANAMA, Canal Zone : Barro Colorado Island, 28.II.1997, Pickering-Windsor col. ( ACMT) . Paratypes, same locality and collector of the holotype, male, 16-23.X.1996 ( ACMT) , female, 27-XII.1996 ( ACMT), female, 05.II.1997 ( ACMT) , female, 12.II.1997 ( ACMT), 2 males, 30.IV.1997 ( MNRJ),. 2 females, 14.V.1997 ( MNRJ) , female, 21.V.1997 ( ACMT) , female, 28.V.1997 ( ACMT) . Bocas del Toro: 40 km W Chiriquí Grande , female, 13.V.1999, Wappes & Morris col. ( ACMT) . Colón: 4. 5 km El Palenque , male, 25.IV.1992, J. Wappes col. ( ACMT) .

Comments: N. insulorum sp. nov. has a similar pattern of patches as N. univittis (Bates, 1885) , but the stripes of the pronotum are different, N. insulorum has a large patch each side of the middle that encircle a longitudinal dark brown stripe, in N. univittis the lateral patch is almost uniformly grayish, with only a minute round spot dark brown.
