Comparing the larva of  Coleoxestia waterhouseiwith the description of  Sphallotrichus setosusit was observed that both species present epistomal margin prominent medially into a small subconical tubercle, antennae with three antennomeres and supplementary sensorial process minute, labrum fringed, one pair of stemmata, tibiotarsi imbricately spinose, and thorax and abdomen with sub-circular or spineshaped asperites. The larval differences observed are (  Coleoxestia waterhouseiparenthesized): labrum oval (rounded); pronotum with four orange plates (four yellow plates); pronotum densely covered with sub-circular asperites (partially covered with sub-circular asperites); prosternum asperate posterolaterally (asperate basal and laterally); gular sutures feebly raised (indistinct); legs 3-segmented (4-segmented). According to Duffy (1960), the larvae of  SphallenumBates, 1870[actually  SphallotrichusFragoso, 1982] “are not at all typical of the Cerambycini, particularly as only a single pair of ocelli [stemmata] is present and the transverse furrows of the ampullae are feebly defined”. 1455889600 2008-11-17 Jorge Yooki Ito Brazil Carlopolis Material 7 247 7 1 5 1 Parana
