Diagnosis. Ogyges handali resembles O. adamsi Schuster & Reyes-Castillo , by the absence of internal tubercles, the transversal convex clypeus, and the form of the central horn and lateroposterior tubercles. The new species is easily separated of O. adamsi by the abundant setae on anterior corners of metasternum (sparse or bare in O. adamsi ).

Description. Holotype male, black adult: Total length 33.67, elytral length 18.51, pronotal length 8.45, pronotal width 11.16, humeral width 10.31. Head: anterior border of labrum concave. Clypeus thickened, transversely convex, anterior border straight, with a central notch in form of “v”; with rugose sulcus separating from the inclined mediofrontal area. Mediofrontal tubercles small and rounded; internal tubercles absent. Laterofrontal areas roughened. Posterofrontal ridges absent; instead, a transversal ridge (tumose near the central horn) runs between the mediopostfrontal structure and the epicranial sutures, forming the anterior margin of lateropostfrontal areas. Mediofrontal area with several grooves confluent to the clypeus, with a wide, bare, rough fossae present in front of the mediopostfrontal structure. Lateropostfrontal areas glabrous, deep, with several grooves. Central horn long, with apex short and free; posterior 1/3 tumose and clearly differentiated from the lower lateroposterior tubercles and with a deep median longitudinal groove; lateroposterior tubercles lower than central horn, barely marked, separated from central horn and directed forward. Postfrontal groove shallow at middle and laterally deep. Supraorbital ridge brilliant and rugose, with unequal anterior tubercles; posterior 1/2 barely bifurcate but with supraorbital fossae elongate, well marked; external ridge rounded. Ocular canthus with apex slightly swollen, rounded, ventrally extended just to half of eye. Eyes reduced. Eye width = 0.31 mm. Interocular width = 6.61 mm. Head (measured from tips of canthi) 8.03 mm; ratio width of both eyes/head = 0.08. Postorbital pits punctuate setose. Ligula slightly protuberant basally, with apical central tooth small and anterior transversal carina absent; abundant setose punctures on the median area, basally sparse. Lateral lobes of mentum with moderate setose punctures, more abundant towards the brilliant oval lateral basal scars; medial basal mentum glabrous and smooth. Hypostomal process elongate, without lateral depression, wide medially and narrow in the apical third. Infraocular ridge present, short and smooth, surrounded by setose punctures. Mandible with dorsal tooth occupying 1/2 of the length; internal face of mandible in dorsal view granular. Antennal club ( Fig. 5 ) with all three antennomeres very wide and subequal measuring 1.77 mm long and 2.31 mm wide; antepenultimate antennomere narrower than penultimate.

Thorax: Lateral fossa of pronotum without punctures except sparse, rugose micropunctures ahead and behind, only visible at very great magnification. Pronotum with marginal groove narrow and smooth, anterior angles rounded, disc smooth at moderate magnification. Prosternellum wide and brilliant. Mesosternum bare and shiny, without definite opaque/rugose (shagreened) areas. Mesepisternum brilliant. Metasternum with anterior angles punctate setose; disc not delimited by punctures; marginal groove very narrow and rugose, with disperse setae in the anterior 4/5 of its length, posteriorly four times wider than medially.

Elytra: Brilliant, with well-marked striations; with small, defined, moderately deep punctures; junctions of striations 1 and 10 without extra punctures. Anterior border of elytra vertical, smooth, with minute scattered setae between interstriae 2–8.

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

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

Aedeagus: In ventral view phallus globose; parameres and phallobase partially separated. In dorsal view, ventrodorsal basal sclerotizations of the phallus present ( Fig. 6 ).

Variation in paratypes (n = 19): Total length 30.54–35.58 ( = 33.00), elytral length = 16.06–19.17 ( = 17.97), pronotal length = 7.5–8.76 ( = 8.44), pronotal width = 9.7–11.54 ( = 11.03), humeral width = 9.16–11.27 ( = 10.36).

Material examined. 49 specimens.

Type material. Holotype male: GUATEMALA: Chiquimula, aldea Santa Rosalía, El Duraznal, cerca del Plan de la Arada , 11 VI 2011, 14 o 31'30.4''N, 89 o 22'47.3''W, 1668 m, bosque nuboso, Col. E.B.

Same data except aldea El Duraznal , cerca de La Mesilla, 1630 m, 20 VIII 1998, Cols. E. Cano & J. Monzón (5) .

Holotype deposited at UVGC, paratypes deposited in UVGC, USAC, IEXA, IBUNAM, SNM, and MNHN.

Etymology. Named in honor of Commander Dr. Schafik Handal, officially recognized as “Hijo Meritísimo de la Ciudad de San Salvador ” and “Honor al Mérito Centroamericano”, for his efforts in favor of the peace in Central America.

Distribution. The species is known only from the fragmented cloud forests of Cerro Montecristo between 1640–1900 m in Guatemala ( Fig. 4 ). The new species should be present in the protected forest of the El Salvador portion and the bigger forest of the Honduran portion.
