Description
Medium-sized species, body length 15 – 22 mm, body completely black to dark brown, antennal club yellow. Head: male with clypeus wide, clypeal margin strongly reflexed and plate-like at middle, central margin very weakly to distinctly concave, with two obtuse and close teeth, lateral margins of clypeus always clearly sinuate, female with clypeus triangular shaped and elongated forward, weakly reflexed and slightly sinuate at middle, head margin obtusely angulate at the clypeo-genal junction. Both sexes with a fronto-clypeal horn, conical and flanked by two small humps tubercle-like located slightly backward, cephalic horn of female smaller, frons always with a strong and medial depression. Clypeal and genal surface completely and shallowly wrinkled, frons with coarse and transverse punctures. Thorax: pronotum simply convex, anteromedial region without humps, anterior margin of pronotum with a thin bead, pronotal punctuation dense, very shallow and evenly distributed, punctures separated by at most two diameters. Elytra convex and swollen, striae well impressed, interstriae weakly convex, elytral punctures very similar to those on the pronotum. Prosternum smooth, with a fine microsculpture, sometimes with few short setae, mesosternum granulose, with coarse and shallow punctures associated to short setae, metasternum finely microsculptured on the superior side and along inner margins of mesocoxae, superior side with evanescent and shallow punctures. Abdomen: pygidium entirely bordered, pygidial surface with very fine punctures. Legs: anterior margin of fore tibiae obliquely truncated, inner and apical angle finely acuminated, with few straight setae at the apex. Apical spur with superior margin bifid, apex of the spur directed inward, apical spur of hind tibiae apically bifurcated. Male genitalia: parameres and endophallic lamellae as shown in Figure 3 View Figure 3 (e – g).
Distribution
Brazil: Mato Grosso, Rondônia, Pará; French Guiana: Cayenne ( Figure 8 View Figure 8 (b)) .
Species mostly associated to Amazon forests, also a few specimens known from the Brazilian cerrado.
Remarks
The morphological features observed in Dichotomius (D.) imitator ( Felsche, 1901) lead us to assign this species to the genus Isocopris . Therefore, Isocopris imitator is proposed as a new combination (ICZN 1999, art. 48). Furthermore, on examining the type specimens of Dichotomius (D.) latistriatus ( Luederwaldt 1935) , we conclude that both I. imitator and D. (D.) latistriatus actually refer to the same species. Thus, according to the Art. 23 of the ICZN (1999), D. (D.) latistriatus is here considered to be a new synonym under I. imitator .
