Description. Holotype male ( Fig. 1a ). Coleoptera : Scarabaeoidea: Ochodaeidae . Length: 9.9 mm . Width: 4.1 mm . Color: Everywhere uniformly dark reddish brown; surface nitid. Head: Surface lacking tubercles, irregularly punctate; punctures moderately large, setose, separated by ~ 4 puncture diameters. Eyes large, globose; lacking ventral projection of canthus. Antennal club subequal to eye in size. Mandibles broadly scooped, basal angle prominent, apices falcate; left mandible with large rectangular internal tooth; right mandible with complimenting tooth reduced, second tooth large, obtuse. Frons weakly convex. Clypeus flat with disc short (at most 1/5 as long as wide), anterior margin strongly beaded; bead thick, rounded, almost as long as disc. Mentum ( Fig. 4 ) slightly wider than long, tumid (not flat); most strongly tumid near base, decreasing anteriorly; surface with 2 lateral and 1 median depression near base, median depression contiguous with oval fovea on disc; fovea continuing anteriorly. Pronotum: Form convex. Surface densely punctate, appearing smooth between punctures, lacking distinct tubercles (at 40× minute tubercle anterior to seta); punctation mixed, with large setose punctures and smaller naked punctures interspersed. Elytra: Form convex, relatively elongate, elytra together longer than wide. Surface with striae moderately impressed, punctate, surface smooth between punctures (except sutural stria with connecting groove); strial punctures separated by> 5 diameters, lacking setae. Intervals irregularly punctate; punctures small, setose, with minute tubercle anteriorly. Legs: Protibia tridentate externally, with short, acute pollex directed anteriorly ( Fig. 1b ). Profemur and mesofemur with apical tooth reduced to rounded lobe. Metafemur with apical fin-like projection with weak tooth in distal fourth. Venter/Abdomen: Metasternum and abdomen sparsely punctate; punctures large with long, erect, golden setae. Pygidium punctate, setose. Stridulatory peg with narrow neck and rounded apex ( Fig. 10 ). Male genitalia: Sclerotized patch on internal sac between parameres broadly oblong with bifurcate end ( Fig. 7 ). Paratype variation. The paratypes show little variation from the holotype , and negligible sexual dimorphism. The clypeus may appear more trapezoidal (truncate medially), and although this is a common sexual dimorphism in ochodaeids this does not appear to be sexually diagnostic in O. modopunctatus . The subapical tooth on the metafemur is present in the holotype and the three largest males but is obsolete in all smaller males and females.
