| Abstrakt: | Abstract: The larvae of 15 species from 7 genera are described, including the first larval descriptions of representatives of Aniara Hope, 1838 (Megacephalini), Cheilonycha Lacordaire, 1843, and Cenothyla Rivalier, 1969 (Cicindelini). Larval characters of Aniara are very similar to those of Megacephala Latreille 1802, the gular suture is Y-shaped and the ventral double sclerite on the prementum is lacking. The bicolored pronotum and the absence of a spine on maxillary palpomere I distinguish the larva of Aniara from those of Megacephala. Cheilonycha and Cenothyla both have larval characters typical of the Cicindelini subtribe Prothymina. The gular suture is T-shaped and two pairs of hooks are present on tergite V. Larvae of Cheilonycha are distinguished from those of the similar genera Odontocheila Castelnau, 1834, Cenothyla and Pentacomia Bates, 1872 by less sclerotized, indistinct abdominal sclerites, indistinct abdominal sclerites and by a pronotum with more than 40 setae and a setiferous posterolateral keel. It is possible to distinguish all described species of Odontocheila, Cenothyla and Pentacomia in the larval stage, but impossible to separate the larvae of these three genera at the generic level. Cenothyla varians (Gory, 1833) is different from the known larvae of Odontocheila and Pentacomia by the following character combination: yellow head capsule+pronotum with conspicuous long and dark setae anteriorly+flattened setae lacking. Short ecological notes on the species are given. A larval key is presented at the generic level, containing 12 of the 16 Brazilian cicindelid genera. |
