Inermestoloides drumonti sp. nov.

( Figs. 12–15 )

Inermestoloides praeapicealba ; Martins & Galileo, 2002: 3 (error of identification).

Description. Female. Integument dark- brown, almost black on some regions; scape yellowish-brown on basal 2/ 3, brown on distal third; antennomere III brown; antennomeres IV reddish-brown on basal half, brown on distal half; antennomere V reddish-brown on basal third, gradually dark-brown toward apex; antennomere VI yellowish on basal half, dark-brown on distal half; antennomere VII brown on basal third, gradually dark-brown toward apex; antennomere VIII yellowish on almost entire basal 2/3, dark-brown on remaining surface; antennomere IX reddishbrown on narrow basal region, dark-brown on remaining surface; antennomere X yellowish on basal half, darkbrown on distal half; antennomere XI light reddish-brown on basal and distal fifth, brown on remaining surface; elytra with large, irregular, slightly distinct, dark reddish-brown area on basal half; base of femora dark reddishbrown; tibiae dark-brown on basal third, light reddish-brown on remaining surface, except for wide, brown ring about middle (wider on meso- and metatibiae); tarsomeres I, II and V reddish-brown, tarsomere III brown.

Head. Frons rectangular, finely, abundantly punctate ( Fig. 12 ); with moderately dense, ochraceous pubescence (more yellowish on small area between antennal tubercles) interspersed with white setae; with some long, erect setae close to lower eye lobes. Area between upper eye lobes with sculpture and pubescence as on frons, except for glabrous central area and macula with yellowish pubescence centrally. Area between upper eye lobes and prothoracic margin centrally glabrous, with ochraceous pubescence on each side of glabrous area, yellowish-white on remaining surface. Area behind upper eye lobes with yellowish-white pubescence close to eye, glabrous close to prothorax; area behind connection of ocular lobes with ochraceous pubescence, glabrous close to prothorax; area behind lower eye lobes, finely, abundantly punctate, with yellowish-white pubescence close to eye, interspersed with sparse, erect, long setae, glabrous close to prothorax. Ventral side of head shiny, glabrous, except for submentum with ochraceous pubescence. Distance between lower eye lobes 0.4 times length of scape; distance between lower eye lobes in frontal view 0.6 times length of scape. Antennae 1.5 times elytral length, reaching elytral apex at about middle of antennomere X; scape, pedicel and antennomeres III–X with sparse, erect setae ventrally; antennal formula (ratio) based on antennomere III: scape = 1.40; pedicel = 0.40; IV = 1.36; V = 1.04; VI = 0.92; VII = 0.84; VIII = 0.64; IX = 0.60; X = 0.48; XI = 0.48.

Thorax. Prothorax subcylindrical, slightly wider than long (1.05 times); sides with small, rounded, slightly distinct tubercle about middle. Pronotum coarsely, abundantly punctate; with ochraceous pubescence laterally, interspersed with short white, setae, with whitish setae centrally, mainly on basal half, interspersed with ochraceous pubescence (this central area somewhat hourglass-shaped); with, long, erect, sparse setae throughout. Sides of prothorax with sculpture as on pronotum; with ochraceous pubescence, except for small spot with yellowish-white pubescence around lateral tubercle. Prosternum coarsely, moderately abundantly punctate; with yellowish- white pubescence, not obscuring integument. Prosternal process with long, erect, moderately abundant setae. Ventral side of meso- and metathorax with yellowish-white pubescence, more reddish depending on angle of light; mesosternal process with long, erect, moderately abundant setae; metasternum with long, erect, sparse setae. Scutellum with white pubescence. Elytra. Coarsely, abundantly punctate on basal third, gradually sparser toward apex; area around suture marmorated with white pubescence (this area wider on distal half; side of distal half with dense macula with white pubescence, not reaching apex and lateral margin; with moderately long, sub-erect, thick, moderately abundant setae throughout (dorsally mostly dark, laterally mostly yellowish-white); apex rounded. Legs. Femora with yellowish-white pubescence, not obscuring integument, interspersed with long, sparse setae.

Abdomen. Ventrites with yellowish-white pubescence, not obscuring integument, interspersed with long, erect, sparse setae (small area around each setae glabrous); apex of ventrite V truncate.

Dimensions (mm), holotype female. Total length, 4.95; prothoracic length, 1.10; anterior prothoracic width, 1.20; basal prothoracic width, 1.00; humeral width, 1.50; elytral length, 3.40.

Type material. Holotype female from BRAZIL, Amazonas: Reserva Ducke (26 km NE Manaus; in Licania micrantha Miq. ( Chrysobalanaceae )), 15.XI.1995, Hurtado J. C. G. col. ( INPA)

Etymology. The new species is named after Alain Drumont (IRSNB) for his friendship and constant help.

Remarks. Inermestoloides drumonti sp. nov. can be separated from the other species of the genus by the features pointed in the key to species.

Martins & Galileo (2002), based on a male specimen from Brazil (Amazonas), redescribed I. praeapicealba . Nevertheless, the specimen used by them (holotype of the new species) does not correspond to the true I. praeapicealba (holotype, Figs. 5, 7 ). According to Martins & Galileo (2002), the specimen was a male belonging to INPA. However, the specimen is a female. Unfortunately, the specimen was damaged at some time between 2002 and now, because originally it had both antennae and the wings were not exposed.
