DESCRIPTION: Size: Length 4.8; width 1.5 mm. Form (fig. 26): Elongate, elytra somewhat ovate and considerably tapered posteriorly, about two times longer than wide; pron­

otum (fig. 38) moderately transverse; epipleural margin feebly arcuate. Integument: dark­castaneous, intermixture of lighter and darker areas, particularly on elytra. Vestiture: Venter and legs copiously vested with setae that are short and decumbent or long and suberect; dorsum copiously vested with stout, bristlelike setae. Head: Cranium subrugosely punctated; eyes prominently bulging, finely faceted, deeply incised along frontal margin (fig. 27), incision half width of eyes when eye viewed from front; antenna (fig. 29) inserted at lower angle of eye incision, comprised of 10 antennomeres, loosely clubbed, vested with few lengthy setae, setae not longer than length of club articles; scape as long as combined length of funicular antennomeres, pedicel particularly large, subglobose, antennomeres four and six slightly expanded, antennomeres five and seven cylindric, club­antennomeres eight and nine subtrigonal, equal in length, tenth antennomere ovoid, only slightly longer than antennomeres eight and nine; labrum deeply incised (fig. 30); mandible not falciform, dentes poorly developed, anterior dens broadly accuminate (fig. 34), medial and posterior dens minute, mandibular penicillus absent; maxilla well developed (fig. 33), terminal palpomeres digitiform, laterolacinia present; labium well developed (fig. 39), terminal palpomere digitiform; gula trigonal (fig. 28). Thorax: Pronotum moderately transverse, anterior margin sinuous, prominently projecting medially, posterior margin broadly sinuous, subapical depression not very prominent, pronotal disc slightly depressed at sides where discal and paralateral trichobothria are prominent; disc with pair of paralateral swellings; epimeral prolongations only feebly extended mesad; procoxal cavities open; elytra distinctly tapered, surface subrugose, punctations small and shallow; epipleural margin feebly explanate; mesoscutellum quadrate­transverse (fig. 31); protibia with stout spines, protibial spur absent, protarsus with three pulvilli; mesotibia with one spur, mesotarsus with three pulvilli; metatibia with one spur, metatarsus with one pulvillus; tibial spurs not particularly elongated; metabasitarsus much longer than metatarsomere two; tarsal claws with small basal dens. Abdomen: Six visible sterna; pygidium broad­scutiform. Male Genitalia: Ae­ deagus (fig. 35) lanceolate; interspicular plate of spicular fork slender (fig. 36), not bifid distally; parameres highly reduced.

DISTRIBUTION: These insects are known only from southern Brazil.

ETYMOLOGY: The generic name Chaetophloeus is a Greek compound name formed from chaete (long hair) and from phloeus (bark of trees). I refer to bristlelike hairs of these tree­dwelling beetles.
