Key to the species of Hybreoleptops

1. Mandibular scar at apex of a cylindrical and tall pedicel; rostral median carina inconspicuous; prothoracic median sulcus starting from anterior margin of prothorax; elytra with one rounded and short declivital tubercle on interval 3; declivital tubercle on interval 5 absent; central area of ventrite 5 lacking scales; lenticular area of metatibial enclosed corbel setose......... 2

– Mandibular scar at apex of a cylindrical and short pedicel; rostral median carina absent, or present and strongly developed (never inconspicuous); prothoracic median sulcus starting at level of coxa 1 or represented by discontinuous incisions; elytra with short conical declivital tubercle on interval 3; conical declivital tubercle on interval 5; ventrite 5 completely covered by subcircular scales; lenticular area of metatibial enclosed corbel lacking setae............. 3

2. Mandibular scar with conical protuberance; rostrum with strongly developed lateral convexities which delimit a median sulcus; scape reaching middle line of eye when resting in scrobe; prothorax with anterior impression; prothoracic median sulcus not reaching base; protruding humeri constituted by basal convexities on interval 7; ventrite 5 with white seta-like scales; prothorax vestiture lacking stripes................ H. santiagensis n. sp.

– Mandibular scar flat; rostrum with slightly developed lateral convexities; scape reaching posterior margin of eye when resting in scrobe; prothorax lacking anterior impression; prothoracic median sulcus ending at base; protruding humeri constituted by basal convexities on intervals 5–7; ventrite 5 with white subcircular scales; prothoracic vestiture showing a white stripe at both sides of median sulcus, followed by an iridescent pink stripe, followed by a new white stripe........................... H. juanjosei n. sp.

3. Rostral central carina strongly developed; prothoracic vestiture with medio-dorsal white stripes................ H. xanthomelas

– Rostral central carina absent; prothoracic vestiture lacking medio-dorsal white stripes...................... 4

4. Scape reaching posterior margin of eye when resting in scrobe; prothoracic median sulcus absent (if present, discontinuous); base of intervals 3 and 4 with iridescent pink stripe which ends at the fourth or fifth puncture of the corresponding striae; base of interval 9 with a similar stripe; both declivital tubercle and the area between them coloured equal to basal area of intervals 3 and 4; basal area of interval 3 showing abundant costate seta-like scales.... H. aureosignatus

5. Prothoracic median sulcus not reaching base; prothorax with anterior impression; femora integument completely covered by subcircular scales; vestiture uniform gold; elytra and prothorax lacking lateral white stripes; interval 5 with slightly developed tubercle behind declivital tubercle........ H. vestitus

– Prothoracic median sulcus reaching base; prothorax lacking anterior impression; femora integument reddish and lacking scales; elytra and prothorax with lateral white stripes; remaining areas of prothorax and elytra black; interval 5 without slightly developed tubercle behind declivital tubercle.....
