description: Decaphloeus Opitz, new genus   
 Type Species. Epiphloeus vitticollis Schenkling, 1900: 397. By present designation.   
 Diagnosis. From superficially similar specimens of Epiphloeus Spinola these epiphloeines may be distinguished by their 10 antennomeral antenna. The antennae of Epiphloeus specimens comprise 11 antennomeres.   
 Description. Size: Length 4.0-10.0 mm; width 1.2-3.0 mm. Form: Oblong subrectangulate; elytra a little more than twice length than width, epipleuron laterally positioned, epipleural margin subarcuate, posterolateral margin gradually curved towards elytral apex. Vestiture: Cranium and eyes vested profusely with stout white setae; pronotum loosely matted with stout white setae; elytral disc vested with primary (1 o) setae and secondary (2 o) setae, 1 o setae stout, erect, and dark, particularly conspicuous along epipleural and sutural margins, 2 o setae short, decumbent, and white or black, latter may be matted into fascia-like aggregates; elytral trichobothria prominent near epipleuron. Head: Cranium rugosely punctate; eyes very bulgy, finely faceted, ocular notch angle acute at innermost point; antenna capitate, inserted at lower angle of eye incision, comprised of 10 antennomeres, loosely clubbed, scape not particularly elongated, as long as combined length of pedicel and antennomeres 3-4, scape capitate, funicular antennomeres 3-7 slightly increasing in width, 9 th and 10 th oblong triangular, 10 th antennomere oval; labrum deeply incised; tormal processes horizontal and not conjoined; mandible robust, dentes well developed, mandibular pinicillus very small; maxillary and labial terminal palpomeres digitiform, laterolacinia present; frons not very wide; gular sutures strongly converging; gular processes very small. Thorax: Pronotum transverse, lateral tubercle prominent, disc finely punctate, pronotal arch roughly punctate, anterior margin curvate, posterior margin straight, anterior transverse depression moderately developed, disc of pronotal proper with elevations and depressions, paralateral tumescences prominent, depressed obliquely at sides where discal trichobothria are prominent; pronotal projections slightly extended to middle; lateral carina not extended to anterior margin of pronotum and confluent posteriorly with pronotal hem; procoxal cavities open; prointercoxal process linear, not laterally expanded distally; metendosternite without furcal lamina; elytra oblong subrectangulate, epipleural margins, briefly subparallel then gradually becoming more rounded, then gradually converging towards sutural margin, epipleuron laterally positioned, ends at elytral middle, punctations small, profusely distributed on elytral disc and becoming progressively smaller to distal limit of disc, epipleural margin extended in basal twothirds then considerably narrowed to posterior third, elytral trichobothria present near epipleural margin; mesoscutellum transverse; profemora particularly robust; tibial spur formula 0-1-1, tarsal pulvilli formula 3-2-1, anterior margin of tibia spinous; tarsal claws with large basal denticle. Abdomen: Narrows to posterior, six visible sterna; pygidium transverse, sixth visible sternum incised distally in males, not incised in females. Male Genitalia: Not available for study.   
 Distribution. This New World genus is known from Bolivia and Brazil.   
 Etymology. The generic name Decaphloeus is masculine and stems from the Latin decem (= ten) and the Greek phloeus (= on bark). But, I want to focus on the antenna, which comprise 10 antennomeres.
