Genus Alloblackburneus Bordat, 2009 sensulato

Alloblackburneus Bordat, 2009: 124

Type species. Alloblackburneusacutulus Bordat, 2009 byoriginal designation.

Diagnosis. Small size species (length 2.5-5.0 mm), oblong, convex, more or less shiny, glabrous or with elytra more or less diffusely pubescent, rarely also pronotum laterally pubescent. Reddish, brownish-red or rarely piceous. Head withepistome moreor less coarsely punctured; clypeus sinuate atmiddle, angulate or roundat sides; genaenot or feebly protruding fromthe eyes; frontalsuture without tubercles. Pronotum transverse, simply ordually punctured; borderedat base, rarelyedge shortly interruptedmedially. Scutellum small, triangular. Elytraregularly oval ortapered toward apex; rarely epipleuralcarina subdenticulate at shoulder and shortly bristled; striae fine, subcrenulate; interstriae flat, feebly or strongly convex, sometimes roof-shaped, minutely sparsely punctured or with punctures serially arranged near striae. Fore tibiae distally tridentate and proximally not or feebly serrulate on outer margin; upper side distinctly punctured. Middle and hind tibiae withfeeble but distincttransverse carinae on outer face; apically fimbriate with spinules more or less elongateand irregularly or progressively unequal. Pygidium densely and coarsely or sparsely and superficially punctured; each puncture with a rather elongate recumbent hair; apical margin with several setae rather short and sparse. Sexual dimorphism shown in males mainly by more deeply excavate metasternal plate; sometimes by the shape of the protibial spur and by more transverse and less densely punctured pronotum. Aedeagus with parameres more or less abruptly curved and acuminate apically; therein usually with a clump of dense hairs. Epipharynx moderately transverse, widely roundat sides, with anterior margin distinctly sinuate at middle; epitorma conical; corypha not protruding beyond front margin and with two strong apical spiculae; pedia rather densely pubescent toward epitorma and with many stout chaetae irregularly scattered; chaetopariae short and dense.

Distribution. Afrotropical, Nearctic and Neotropical regions.

Remarks. Afew additional Afrotropical speciesprobably belong to Alloblackburneus as herein diagnosed. At present they are placed in several genus group taxa (e.g. Blackburneus, Pleuraphodius Schmidt , Trichaphodius Schmidt , etc.). To resolve their taxonomy requires systematic revisions with studies of type materials. Unfortunately, types seem to be lost for most of them.
