Fig. 26 View FIGURES 26–29

Diagnosis: Resembles S. emarginata (Texas) and S. denticulata ( Mexico), in the dense setose vestiture, but is quite distinct in sculpture. The pronotum has sub-parallel ridges along the midline that have weakly divided elevations at the apex and base (not quite as strong as S. emarginata ), the elytral sculpture consists of arcuate rows of small round nodules, with one distinctly larger and teardrop shaped nodule at the start of the apical declivity. The dense mottled tomentose vestiture and banded apex of the parameres are also quite distinct.

DESCRIPTION (male): Length 11–22 mm. Vestiture consisting of dense setae, short and bristle like to tomentose, color mottled darks and light. Anterior clypeal margin concave. Antennomere 2 short and transverse; 3 only slightly longer than 4; antennomeres 1–6 with short dense golden setae on apical margin. Labium with two lateral tufts and few median setae inserted in broad depression; subgenal ridge thickened with median depression or pit. Pronotum with arcuate lateral ridges; lateral margin sinuate with weak notch; hind angles obtusely rounded. Elytral sculpture with arcuate rows of nodules in 3 rd and 5 th elytral intervals; large teardrop shaped nodule in 3 rd interval at start of declivity. Femoral nodules present only on pro and meso femora. Ventrites 1–3 flattened medially.

Parameres strongly narrowed at the tip almost fused, weakly emarginate; near apex with distinct color band, light yellow at the tip.

Distribution: Far southern Mexico through Central America as far south as Nicaragua.

ETYMOLOGY: This species is named in honor of Dr. Charles A. Triplehorn, our academic parent (to MAI) and grandparent (to IAF), whose excellent species level revision of Zopherus was motivation to understand the other genera of the tribe, and in recognition of the considerable unpublished observations on the group which were kindly shared with us.

Notes: Specimen data report individuals collected from the trunk of a rotten tree, another on logs at night, and a handful on “fungusy” logs. Specimens were collected from 10–290 m and apparently inhabit lowland tropical wet forests. A long series of specimens was collected over several days in a rain-forested creek valley with steep sides among large rotten tree trunks covered with a garden of different bracket fungi and mushrooms both on and under the logs (W. Steiner pers. comm.).
