(Figs. 1–4)
Description. Female (♀). Head black dorsally; sides and part of ventral side dark- brown; gula yellowish; submentum reddish-brown. Mouthparts light reddish-brown, except yellowish last segment of maxillary and labial palpi. Anteclypeus and labrum reddish-brown laterally, yellowish centrally. Scape with condyle reddish-brown, basal 3/4 yellow, distal 1/4 brown. Pedicel and antennomere III light reddish-brown on basal 1/4, dark-brown on remaining surface; antennomeres IV–V and VII yellow on base (this area larger on IV), becoming gradually reddish-brown toward apex of basal 3/4, dark-brown on distal 1/4; antennomere VI and VIII yellowish-white on basal 4/5, dark-brown on distal 1/5; antennomere IX reddish-brown on basal 1/4, dark-brown on remaining surface; antennomere X yellowish-white on basal 2/3, dark-brown on distal third (missing antennomere XI). Pronotum black, except reddish-brown anterior margin. Sides of prothorax black, gradually dark-brown toward ventral side. Ventral side of thorax and abdomen dark-brown. Elytra black, marmorated with orange-brown areas (Fig. 1). Femora dark-brown from base to about basal third of club, yellowish-brown on remaining surface. Tibiae light reddish-brown on about basal quarter and distal fifth, yellow between these areas, except for dark-brown ring close to distal fifth. Tarsi brown, except yellowish-brown segment V.
Head. Frons rectangular, moderately coarsely, abundantly punctate (Fig. 4); central area with sparse, ochraceous setae; sides with dense, ochraceous setae, except for white setae close to lower eye lobes, and macula with white pubescence centrally, close to base of antennal tubercles; with one long, erect, dark seta close to lower eye lobes. Vertex moderately abundantly punctate (punctures finer than on frons); with ochraceous pubescence, except for white pubescence close to upper eye lobes. Area behind eyes with ochraceous pubescence from behind upper eye lobes to about middle of lower eye lobes, then with white pubescence close to eye, glabrous, toward prothorax; coarsely, densely punctate on area close to pubescence (not obliterated by pubescence on distal region of lower eye lobes). Submentum with yellowish pubescence interspersed with some long, erect setae. Genae with white pubescence. Distance between lower eye lobes 0.55 times length of scape; distance between lower eye lobes in frontal view 1.05 times length of scape. Antennae (from base of scape to apex of antennomere X) 1.45 times elytral length, reaching elytral apex at distal quarter of antennomere IX; light area of antennal segments with white pubescence; dark area of antennal segments with brown pubescence; ventral side of antennomeres III–IV with thick, dark, sparse setae (more abundant on III); antennal formula (ratio) based on antennomere III: scape = 1.35; pedicel = 0.43; IV = 1.48; V = 1.00; VI = 1.22; VII = 0.95; VIII = 0.95; IX = 0.82; X = 0.74.
Thorax. Prothorax subcylindrical, wider than long (1.2 times wider than long); sides without gibbosity, but rounded on basal half, convergent toward base. Pronotum coarsely, densely punctate (Fig. 1); center of anterior region sub-flat; with slightly distinct carina from base to base of sub-flat area; center with hourglass-shaped region with dark pubescence, distinctly exposing punctures; sides with ochraceous pubescence, interspersed with white pubescence close to narrowest area of hourglass-shaped region; base with band with ochraceous pubescence laterally, white centrally; anterior margin with yellowish-brown pubescence interspersed with white pubescence. Sides of prothorax with ochraceous pubescence, except for two subrounded with dark pubescence distinctly exposing punctures; punctation as on pronotum. Prosternum, prosternal process, mesosternum, mesosternal process, metepisterna, and metasternum coarsely, abundantly punctate; with yellowish-white pubescence (more ochraceous depending on angle of light), not obscuring integument. Anterior margin of mesosternal process abruptly inclined toward mesosternum. Mesepimera and mesepisterna with ochraceous pubescence. Scutellum with white pubescence. Elytra. Coarsely, abundantly punctate throughout, except for finer, sparser punctures on distal area; pubescence ochraceous, absent or sparser on some areas, marmorated with white pubescence, mainly centrally (Fig. 1); with thick, dark, suberect, sparse setae. Legs. Femora with yellowish-white pubescence, not obscuring integument. Tibiae with yellowish-white setae, interspersed with dark, thick, erect setae dorsally on dark-brown ring.
Abdomen. Ventrites coarsely, abundantly punctate; with yellowish-white (more ochraceous depending on angle of light) pubescence, not obscuring integument. Apex of ventrite V rounded.
Dimensions (mm), holotype. Total length (including mandibles), 5.15; prothoracic length, 1.05; anterior prothoracic width, 1.15; basal prothoracic width, 1.10; largest prothoracic width, 1.25; humeral width, 1.65; elytral length, 3.60.
Type material. Holotype female (♀) from ECUADOR, Napo: 2 km N Ahuano, 13–14.IX.2000, F. T. Hovore col. (CASC).
Etymology. The specific epithet refers to the country where the type was collected.
Remarks. Inermestoloides ecuadorensis sp. nov. can be separated from the other species of the genus as pointed out in the key to species.
