Smith, Sarah M. & Cognato, Anthony I., 2010, A taxonomic revision of Camptocerus Dejean (Coleoptera: Curculionidae: Scolytinae), Insecta Mundi 2010 (148), pp. 1-88 : 78

Hosts. Protium amazonicum Swart (Burseraceae) , Protium sp.

Biology. Camptocerus pseudoangustior infest 2 - 5 cm diameter branches. The maternal gallery extends transversely through the stem to near the opposite side. Females create a vertical maternal gallery extending above and below the entrance tunnel in the pith of small branches and twigs. Two short radial maternal galleries are created in larger stem. Females lay single eggs along the maternal gallery in wide niches cut at right angles to the gallery and plugged with boring dust. Larvae enlarge their cradles parallel to the maternal gallery and parallel to the grain of wood. Galleries strongly resemble those of C. aterrimus . Beetles aggregate in leaves around host trees and perform maturation feeding on leaves ( Smith 2009).

Discussion. Specimens of this species have been commonly identified as C. angustior in collections and keys (ex. Wood 2007).

Etymology. Pseudo - (G) = false, - angustior = a Camptocerus species.
