Diagnosis. Ogyges toriyamai seems closely related to O. mutenroshii from Cusuco National Park, by the size, the elytral and metasternal punctures and the medially constrained central horn. Is distantly similar to O. nahuali and O. cavei by the small and shallow elytral punctures, and by the strong punctures surrounding the metasternal disc. The new species is easily distinguished by the opaque aspect of elytra.

Description. Holotype male, black adult with blue iridescence. Total length 32.45, elytral length 17.26, pronotal length 9.05, pronotal width 11.58, humeral width 11.36. Head: anterior border of labrum slightly concave. Clypeus inclined; anterior border straight, with very small central invagination, without suture separating it from the mediofrontal area. Mediofrontal tubercles conical and well defined. Mediofrontal area smooth, without internal tubercles and posterofrontal ridges. A wide, bare, smooth fossa present in front of the mediopostfrontal structure. Lateropostfrontal areas wide, glabrous and coarsely rugose, anterior border strongly keeled with keel connected to mediopostfrontal structure. Central horn long, narrow, dorsally excavated on both sides to the level of the lateroposterior tubercles, with apex free and slightly directed upward, without median longitudinal groove posteriorly; lateroposterior tubercles somewhat elongate, joined at center to the posterior keel of the central horn. Postfrontal groove deep laterally. Supraorbital ridge with equal anterior tubercles; posterior 1/2 bifurcate with supraorbital fossa deep; external ridge well marked. Ocular canthus with apex straight or slightly swollen, ventrally covering the half of eye. Eyes reduced. Eye width = 0.5 mm. Interocular width = 6.31 mm. Head width = 8.0 mm; ratio both eye widths/head width = 0.12. Postorbital pits located immediately behind the external ridge oval and punctate. Ligula slightly protuberant basally, with small apical central tooth (eroded in old specimens), without anterior ventral transversal carina and with setaceous punctures medially. Lateral lobes of mentum with abundant setose punctures; basal lateral scars oval, punctate setose and shagreened except on apical border; medial basal mentum bare and shiny, slightly rugose laterally. Hypostomal process elongate, without lateral depression, wide medially and narrow in apical third. Infraocular ridge present, short and smooth, surrounded by striate, setose punctures. Dorsal tooth of mandible occupies 1/2 length; internal dorsal face of mandible smooth. Antepenultimate antennomere of antennal club slightly longer (or subequal) than penultimate, less wide than the penultimate; antennal lamellae slightly concave dorsally ( Figs. 19–20 ), 1.77 mm wide and 1.73 mm long.

Thorax: Lateral fossae of pronotum only with some micropunctures of rugose aspect, visible at great magnification. Pronotum with marginal groove narrow and smooth, laterally with abundant micropunctures of rugose aspect (striate), visible at great magnification; anterior angles rounded; disc smooth. Prosternellum brilliant at center, shagreened at anterior 2/5 and posterior 1/5. Mesosternum glabrous; lateral depressions elongate and rugose (shagreened). Mesepisternum with oval, elongate, shagreened area. Metasternum anterior angles glabrous; disc delimited by 38–40 well-marked punctures (some partially fused) on each side; marginal groove glabrous, narrow and slightly striate, posteriorly two times wider than medially.

Elytra: Opaque, with sparse blue iridiscence under direct light; striations marked and with defined punctures, markedly deeper and wider between striae 5–10; junctions of striations 1 and 10 with some extra punctures. Interstriae with abundant brown micropunctures visible at great magnification, particularly on interstriae 7–10. Scarcely minute setae on interstriae 2–6 on vertical anterior border of elytra.

Legs: Profemur with anterioventral groove marked; metafemur moderately widened; mesotibia with one or, occasionally, two spines (the second smaller).

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

Aedeagus: In ventral view phallus globose; parameres and phallobase partially separated ( Fig. 20 ).

Variation in paratypes (n = 3): Total length 28.29–31.06 (=30.00), elytral length 15.65–17.46 ( = 16.74), pronotal length 7.67–8.69 ( = 8.24), pronotal width 9.69–11.21 ( = 10.68), humeral width 9.26–10.48 ( = 10.09). Disc of metasternum delimited by 15–40 well-marked punctures (some partially fused and/or striated) on each side.

Material examined. 4 specimens.
