Diagnosis. Ogyges cavei is a large species that resembles O. nahuali Schuster, Cano, & Boucher , by the indistinct elytral punctures and the metasternal disc delimited by strong punctures, but is easily separated by the presence of internal tubercles and the tip of central horn directed upward.

Description. Holotype female, black adult. Total length 40.78, elytral length 22.18, pronotal length 11.12, pronotal width 14.41, humeral width 13.64. Head: anterior border of labrum slightly concave. Clypeus inclined, anterior border straight, with two setae on lateral borders, with a weak platform separating it from the smooth mediofrontal area. Mediofrontal tubercles small and rounded; internal tubercles and posterofrontal ridges present. Laterofrontal areas smooth, with sparse, large setae on lateroclypeal pits. A small, bare, smooth fossa present in front of junction of mediopostfrontal structure and posterofrontal ridges. Lateropostfrontal areas glabrous and smooth. Central horn moderately long, with apex directed upward and slightly forward, without median longitudinal groove posteriorly; lateroposterior tubercles long, rounded, curved backward and almost reaching the supraorbital tumosity and not separated from central horn. Postfrontal groove smooth and shallow, barely deeper at sides. Supraorbital ridge with equal anterior tubercles; supraorbital fossae present and small, posterior 1/2 not bifurcate; external ridge not marked. Ocular canthus with apex slightly swollen, covering more than half of eye. Eyes reduced. Eye width = 0.42 mm. Interocular width = 7.85 mm. Head (measured between tips of canthi) = 9.37 mm; ratio width of both eyes/head = 0.09. Postorbital pits shallow, with minute, punctate setations. Ligula slightly protuberant basally with apical central tooth small with anterior ventral transversal carina present and complete; setose punctures on the median area. Lateral lobes of mentum with abundant setose punctures, except on the moderately protuberant rounded apex; medial basal mentum glabrous; lateral basal scars elongate to sides, punctate-setose and opaque. Hypostomal process elongate, without lateral depression, wide medially and narrow in the apical third. Infraocular ridge present, short and smooth, proximal area declivous and setose, distal area punctate-setose. Mandible with dorsal tooth occupying 1/2 of his length; internal face in dorsal view slightly opaque, not granular. Antennal club ( Figs. 2–3 ) concave with all three antennomeres very wide and subequal; penultimate antennomere slightly wider than the antepenultimate.

Thorax: Lateral fossa of pronotum without punctures except minute, striate punctures ahead and behind, visible at high magnification. Pronotum with marginal groove narrow and smooth, anterior angles rounded, disc brilliant with numerous, minute, opaque punctures visible at moderate magnification. Prosternellum brilliant at center and posteriorly, opaque at anterior 1/3 and sides. Mesosternum with lateral depressions elongate and rugose (shagreened). Mesepisternum with elongate rugose area (shagreened), more marked and oval apically. Metasternum anterior angles with sparse, minute setae; disc delimited by 31–32 well-marked punctures on each side (some partially fused); marginal groove glabrous, narrow, rugose, posteriorly two times wider than medially.

Elytra: Striations marked; with minute, weakly-defined, superficial punctures, deeper and wider between striae 6–10; junctions of striations 1 and 10 with sparse extra punctures. Anterior border of elytra vertical, with minute setae on interstriae 2 (or 1) to 9.

Legs: Profemur with anterioventral groove marked; metafemur moderately elongate; mesotibia with one spine.

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

Variation in paratype: Total length 38.91, elytral length 20.8, pronotal length 10.75, pronotal width 13.64, humeral width 11.63. Disc of metasternum delimited by 35–38 well-marked punctures on each side and with 14–16 small punctures directly on sides of disc.

Material examined. 2 specimens.

Holotype and paratype deposited at UVGC .

Etymology. Named after the notable entomologist Ronald D. Cave, in honor of his studies on the entomological diversity of Honduras.

Distribution. The species is known only from two widely separated cloud forests between 1800–2100 m, from Olancho and Comayagua in Honduras ( Fig. 4 ).
