Antennae reaching elytral apex at antennomere VII; scape with short whitish setae, with darker longer setae interspersed; antennomeres finely punctate; III with basal ring of whitish pubescence; IV-XI with whitish pubescence on basal fourth (less evident toward apical antennomeres) and dark pubescence on remaining surface; scape slightly curved basally, subcylindrical; antennal formula (ratio) based on length of antennomere III (only holotype measured): scape = 0.99; pedicel = 0.06; IV = 0.88; V = 0.88; VI = 0.79; VII = 0.72;VIII = 0.65; IX = 0.61; X = 0.54; XI = 0.64.

Thorax: Prothorax transverse, 1.2 times as wide as long (including lateral tubercles); with anterior and posterior constriction;lateral tubercles acute. Surface of pronotum densely and coarsely alveolate, with short, moderately dense dark setae and interspersed sparser longer setae; margins of pronotum and complete median longitudinal band with dense, coarse whitish setae; pronotum with two pairs of weakly elevated gibbosities,anterior pair glabrous. Prosternum with deep transverse sulcus and fine transverse wrinkles; with long, sparse whitish setae on anterior and posterior margins, and short, dense whitish setae laterally;prosternal process subparallel-sided,apex rounded; width at narrowest point equal to ⅛ of procoxal cavity width. Mesoventrite anteriorly impressed, smooth, posteriorly and on mesoventral process with long, sparse whitish setae; mesoventral process emarginate at posterior margin, with apex about ¾ of mesocoxal cavity width.

Metaventrite sparsely, finely punctate; on central area, each puncture with long, erect whitish seta; with short dense whitish setae laterally. Scutellum with short, dense whitish pubescence; apex rounded. Elytra subparallel-sided, almost four times as long as prothorax; with coarse deep punctation from humeri to posterior third, with very fine, dense punctation on posterior third; lateral and sutural margins covered with short and dense grayish pubescence; with oblique band of dense grayish pubescence separating regions of coarse and fine punctation, starting at epipleura and reaching suture; apex of elytra truncate. Femora with short, moderately sparse whitish setae, longer ventrally; tibiae with short whitish setae, with longer setae interspersed.

Abdomen: Ventrites finely, sparsely punctate; with long, sparse whitish setae on central region and short, dense setae laterally, obscuring integument; ventrites gradually decreasing in width toward last ventrite; apex of ventrite V truncate.

Terminalia: Tergite VIII ( Fig. 4A ) with distal margin truncate and lined with both, long and short yellow setae. Variation: In some specimens the orange fascia of elytra can be longer than in the holotype, reaching the apical fourth ( Fig. 3 ). This variation was observed only in females, but it is probably an intraspecific variation, not associated to sexual dimorphism.

Total length, 10.5; prothoracic length, 1.8; anterior prothoracic width, 1.3; posterior prothoracic width, 1.4; widest prothoracic Type material: Holotype ♀ ( IAVH): Colombia, Cauca (PNN Munchique Sector La Romelia , 02°38 ′ N, 73°52 ′ W, 2,650m), 24.V-09.VI.2004, Fino E. col. Malaise, IAvH-E-203768 .

Description (Female): Integument dark brown with metallic-blue reflections. Mouthparts, apex of scape and antennomeres, gradually to the apex of antenna, light- er; coxae, trochanters and femora laterally and ventrally, and basal ¾ of metatibiae reddish-brown.

Head: Vertex with dense, coarse, shallow punctures, and dense, erect, short setae, denser and longer around margin of upper eye lobes and base of antennal tubercles; frons and antennal tubercles smooth except for a few punctures, with short, dense setae laterally; basal ¾ of clypeus with long yellowish setae; labrum with long,erect whitish setae; genae short, apex truncate, with dense whitish setae. Distance between upper eye lobes about 2.5 times width of one upper lobe. Gulamentum smooth, strongly impressed anteriorly, with long, sparse whitish setae.

Thorax: Prothorax transverse, 1.22 times as wide as long (including lateral tubercles); with anterior and posterior constriction; lateral tubercles rounded. Surface of pronotum densely, coarsely, confluently punctate; with short, dense yellowish setae, denser laterally and medially, forming median longitudinal band from anterior to posterior margin; with two pairs of weakly elevated gibbosities. Prosternum with deep, transverse sulcus, smooth, with long, sparse whitish setae on anterior margin and short and dense whitish setae laterally; prosternal process gradually narrowed toward truncate apex; width at narrowest point equal to ⅙ of procoxal cavity width. Mesoventrite with long, sparse whitish setae, and short, dense whitish setae laterally; mesoventral process emarginate at posterior margin, with apex equal to ¾ of mesocoxal cavity width. Mesanepisternum, mesepimeron and metanepisternum with short, dense whitish setae obscuring integument. Metaventrite finely punctate, at central area each puncture with long, erect whitish seta; with short dense whitish setae laterally. Scutellum with short, dense pubescence; apex rounded. Elytra gradu- ally narrowed toward apex, almost five times as long as prothorax; with coarse, deep punctation from humeri to midlength and with fine, dense punctation on posterior half; margins covered with short, dense grayish pubescence; with oblique band of dense grayish pubescence separating anterior and posterior half, starting at epipleura and almost reaching suture; apex of elytra obliquely truncate, with small dentiform projection at sutural angle. Femora with short, dense whitish setae, longer, sparser ventrally; tibiae with short whitish setae, denser, darker toward apex. Femora more linear toward metafemora; length of metatarsomere V twice length of metatarsomere II.

Abdomen: Ventrites finely, sparsely punctate; with both, short and long, sparse setae on central region, and short, dense setae laterally obscuring integument; ventrites gradually decreasing in width toward last ventrite; apex of ventrite V truncate.

Dimensions (mm): Holotype female. Total length, 12.4; prothoracic length, 1.8; anterior prothoracic width, 1.4; posterior prothoracic width, 1.6; widest prothoracic width (between apices of lateral tubercles), 2.2; humeral width, 2.7; elytral length, 8.8.

Etymology: A compound of the Latin “ex” (without;denoting privation) and the Greek “spilotos” (spotted), referring to the absence of a spot of grayish pubescence on elytra.

Remarks: Hovorestenia espilota sp. nov., resembles H.thalassina ( Fig.8 ), but differs by the absence of a spot of grayish pubescence on each elytron, area of finer punctation of the elytra covering almost entire posterior half,and femora dark dorsally and reddish-brown laterally and ventrally. In H. thalassina , each elytron has a spot of grayish pubescence,area of finer punctation of the elytra is placed on posterior fourth, and the femora are reddish-brown on basal third and the remaining surface is dark.
