Taxonomy of Oriental Enicocephalidae (Heteroptera: Enicocephalomorpha) and morphological novelties of new taxa.

The infraorder Enicocephalomorpha represents the basalmost group of Heteroptera, the sister group of all remaining Heteroptera (= Euheteroptera) (ŠTYS 1989). The infraorder, whose unique phylogenetic position was recognized by most modern authors (ŠTYS & KERZHNER 1975), is currently divided into two families, Aenictopecheidae and Enicocephalidae. Some new taxa are described (Results: Parts A-H) and special attention is paid to newly discovered or overlooked morphological characters of the group, some of them important for all the Heteroptera. In Part A is described first member of worldwide distributed genus Systelloderes from the Oriental region, S. loebli Štys & Baňař, 2007 and the term neopatella is established for for sclerites within the femoro-tibial intersegmental membrane. Xenicocephalus josifovi Štys & Baňař, 2008 is described in Part B, representing first known complete adult of this peculiar genus. Unique type of raptorial foreleg among all Enicocephalomorpha is described and illustrated and its function by predation is assumed. In Part C is described new genus Phaenicocleus Štys & Baňař, 2009 from northern Borneo, based on males of three species. New diagnostic characters in Enicocephalomorpha are used. Phaenicocleus granulosus Baňař & Štys, 2011 is described in Part D, based on the..
