Eniclases Waterhouse, 1879

Eniclases Waterhouse, 1879: 66.

Type species.

Lycus luteolus Waterhouse, 1878 by monotypy.

Diagnosis.

Eniclases is similar to Trichalus Waterhouse, 1877 and they share a small to medium sized, dorso-ventrally flattened body; a characteristic shape of a pronotum with acutely projecting posterior angles and a hump in a posterior third of a pronotal margin; nine elytral costae in the humeral part of elytra (four robust primary costae and five weak secondary costae) and a shortened primary costa 1 (Figs 6-50). Unlike Trichalus , the median pronotal areola is absent in Eniclases and only two divergent longitudinal keels are present in the pronotum (Figs 6-29). Additionally, all Eniclases have a characteristic cap-shaped apex of the phallus (Figs 43-50) similar to those of Schizotrichalus Kleine, 1926 ( Bocak 2002). The detailed redescription of Eniclases was published by Bocak and Bocakova (1991).

Phylogenetic relationships.

The shape of the pronotum, shortened elytral costa one, and shape of male genitalia (Figs 6-50) support close relationships of Eniclases and other trichaline genera. At present, the trichaline lineages form a subordinate clade within Metriorrhynchina and consist of Eniclases , Flabellotrichalus Pic, 1921, Microtrichalus Pic, 1921, Schizotrichalus Kleine, 1926, and Trichalus Waterhouse, 1877 ( Bocak 2002, Sklenarova et al. 2014).
