Semanotus undatus Classification Family Cerambycidae > Subfamily Cerambycinae > Tribe Callidiini > Genus Semanotus Diagnostic Features of Larvae Mature larva. Rather similar to that of Hylotrupes bajulus, from which it may be distinguished as follows. Form rather slender, less depressed. Head with front margin broadly piceous. Mouthframe strongly sclerotized beneath antennae. Antenna with second segment Less than twice as long as third. Mandible without a deep longitudinal impression. Ocelli indiscernible. Hypostoma with front margin ferruginous. Maxillary palp with third segment about equal in length to second; dorso-external process of palpifer as long as third segment of maxillary palp. Prothorax with posterior half of pronotum very finely striate; median cleavage line lightly impressed. Pleural discs distinct. Adapted from Duffy (1953). Biology and Economic Importance Members of this tribe are known from various host plant families and several species are considered economically important. Species of this tribe are potentially invasive outside their native range. Selected References to Larvae Specimens Duffy, 1953
