Diagnosis. By the elytra with wide, deep dorsal punctures, O. llama is similar to the “ O. crassulus ” lineage (as suggested by Schuster et al. (2005)). It is easily separated from O. monzoni and O. aluxi by the smaller size, the central horn not free or scarcely free and by the medial central mentum weakly rugopunctate. It can be separated from O. laurae by the mesotibia with two spines (instead of one) and the tumose posterior portion of central horn. From the sympatric or almost sympatric O. crassulus it is separated by the form of aedeagus, with lateral lobes separated from basal piece, and the widest punctures on posterior striae 6–9.

Description. Holotype male, black (dorsum) to dark brown (venter) teneral, with blue iridescence. Total length 22.61, elytral length 11.85, pronotal length 6.23, pronotal width 8.16, humeral width 7.56. Head: anterior border of labrum slightly concave. Clypeus inclined (> 90 o); anterior border straight, lacking a central invagination, with a scabrose (to almost granular) sulcus separating it from the smooth (almost shagreened at great magnification) mediofrontal area. Mediofrontal tubercles rounded and defined; internal tubercles and posterofrontal ridges absent. Laterofrontal areas smooth. Lateropostfrontal areas wide, glabrous, and smooth; a marked or weakly marked keel runs laterally from the mediopostfrontal structure, forming the anterior border of lateropostfrontal areas. A wide, bare, smooth fossa present in front of the mediopostfrontal structure. Central horn short, narrow, with apex weakly free (or almost not free), directed upward, without median longitudinal groove posteriorly; lateroposterior tubercles not elongate, forming an angle directed forward and sideways, separated from the central horn by a groove. Postfrontal groove shallow, medially very narrow (constrained by the extended mediopostfrontal structure), gradually enlarged at sides and almost continuous with the lateropostfrontal areas. Supraorbital ridge with equal anterior tubercles; posterior 1/2 bifurcate with the supraorbital fossae deep; external ridge well marked. Ocular canthus with apex straight or slightly swollen, ventrally covering at least the half of eye. Eyes reduced. Eye width = 0.42 mm. Interocular width = 4.61 mm. Head width (measured between tips of ocular canthus) = 5.85 mm; ratio both eye widths/head width = 0.14. Postorbital pits oval, elongate and covered with sparse setae on external border. Ligula slightly protuberant basally, with small central tooth and without a ventral anterior transversal carina (a tumosity is present); medially with setose punctures. Lateral lobes of mentum with moderate setose punctures, lateral basal scars oval and opaque (shagreened); medial basal mentum shiny, with a few scattered small and scabrous setose punctures, setae long and slender. Hypostomal process elongate, without lateral depression, wide medially and narrow in apical third. Infraocular ridge present, short and smooth, surrounded by striate, setose punctures. Mandible with dorsal tooth occupying 1/2 of his length; internal face of mandible in dorsal view smooth, not granular. Antepenultimate antennomere of antennal club subequal in length but less wide than the penultimate ( Figs. 9–10 ); antennal club measures 1.11 mm wide and 1.23 mm long.

Thorax: Lateral fossae and marginal groove of pronotum with abundant striate micropunctures, visible at great magnification; anterior angles rounded; disc smooth except for scattered shallow micropunctures visible at high magnification. Prosternellum opaque, completely shagreened. Mesosternum glabrous; lateral depressions elongate and rugose (shagreened). Mesepisternum with oval, very elongate shagreened area, reaching the posterior border. Metasternum anterior angles glabrous; disc delimited by 12–16 well marked punctures (some partially fused) on each side; marginal groove glabrous, narrow and smooth, posteriorly two times wider than medially.

Elytra: Opaque, with blue iridescence; striations well marked and with defined punctures, slightly deeper and wider between striae 5–10; anterior 1/3 of sixth interstriae of the width of a puncture of striae 6 or 7; junctions of striations 1 and 10 with some extra punctures.

Legs: Profemur with anterioventral groove marked; metafemur moderately widened; mesotibia with two spines.

Abdomen: Marginal groove of sternite VII incomplete, occupies 3/5 of sternite.

Aedeagus: In ventral view phallus globose; parameres and phallobase separated ( Fig. 10 ).

Variation (n = 30): Total length 19.30–24.49 ( = 22.95), elytral length 11.7–13.24 ( = 12.59), pronotal length 5.60–7.18 ( = 6.38); pronotal width 7.55–8.69 ( = 8.19); humeral width 6.8–8.26 ( = 7.71). Disc of metasternum delimited by 12–24 well marked punctures (some striate or partially fused) on each side.
