Description:

The weevil species Listroderes abditus Enderlein belongs in the subtribe Listroderina. This species had been previously transferred to Antarctobius, based on characters from the adult morphology. However, larval characters suggest that it was placed correctly in Listroderes. A cladistic analysis of this species and nine other rhytirrhinines for which larvae are known was performed, based on 56 morphological characters (32 from larvae and 24 from adults). According to the single cladogram obtained (78 steps, CI = 0.65, and RI = 0.72), L. abditus should be included in Listroderes rather than in Antarctobius. Larval and adult characters were also analysed separately, leading to poorer resolution in comparison with the simultaneous analysis, and suggesting that a stable classification requires the analysis of data from both life stages.
