1. Elytra with orange longitudinal band on humeral region( Figs.2-3 , 7 )...2

— Elytra without orange longitudinal band ( Figs.6 , 8 )..........................3

2(1). Surface of body with fine, sparse setae; head with fine punctation; pronotum with fine and alveolate punctation, anterior pronotal tubercles glabrous; longitudinal band of elytra starting at humeri; body size smaller (average total length from type series= 10.9 mm) ( Figs.1 A-B,2-5). Colombia (Caquetá, Cundinamarca, Huila, Nariño) , Ecuador.............................................. Hovorestenia cleideae sp.nov.

— Surface of body with coarse and dense setae; head with coarse and dense punctation;pronotum with coarse and confluent punctation, pronotal tubercles punctate; longitudinal band of elytra starting beyond humeri;body size larger (average total length = 13.9 mm) ( Fig.7 ). Ecuador............ Hovorestenia humeralis ( Waterhouse,1880)

3(1). Elytra with oblique grayish pubescent band on midlength, without spot of grayish pubescence; apices of coxae and trochanters, base and ventral face of femora, and tibiae reddish brown. ( Figs. 1C , 6 ). Colombia (Cauca)................................. Hovorestenia espilota sp.nov.

— Elytra with oblique pubescent band on posterior fourth and with a pair of grayish pubescent spots at midlength; reddish-brown areas of legs restricted to trochanters and bases of femora and tibiae.( Fig.8 ). Ecuador........... Hovorestenia thalassina Santos-Silva & Hovore,2007
