Genus Pseudocoelotrachelus new genus

Type species. Pseudocoelotrachelus tristaobrancoi new species, here designated.

Description. Rather small species (length 5.0- 5.5 mm); oval elongate, moderately convex, shiny, glabrous. Piceous or reddish brown. Head with epistome gibbous, finely and sparsely punctured; clypeus slightly sinuate at middle, distinctly denticulate or subangulate at sides, genae protruding from the eyes; frontal suture not tuberculate. Pronotum transverse, moderately convex, simply or dually, rather coarsely punctured; lateral margins almost straight, S-shaped before hind angles; latter obtusely round; base not bordered. Scutellum small, narrowly triangular. Elytra elongate, strongly denticulate at shoulder, finely striate; striae more or less distinctly punctured, feebly crenulate; interstriae moderately convex or almost flat, sparsely finely punctured. Fore tibiae distally tridentate and proximally serrulate at outer margin; upper side rather densely coarsely punctured. Hind tibiae with very feeble transverse carinae on outer face, apically fimbriate with progressively unequal spinules. Pygidium very densely and coarsely punctured, punctures setose, pubescence recumbent toward apex; latter with few straight and elongate setae. Sexual dimorphism shown in males by more transverse and less convex pronotum and by the metasternal plate relatively more distinctly excavate. Aedeagus with parameres elongate, feebly curved, acuminate and distinctly pubescent apically. Epipharynx inwardly sinuate at middle of anterior margin, round at sides; epitorma drop-shaped or campaniform; corypha with two strong and curved apical celtes protruding from the front margin; pedia pubescent with two lateral subregular series of few elongate spinules; chaetopariae moderately elongate, not very closely arranged.
