Taxonomie čeledi Enicocephalidae (Heteroptera: Enicocephalomorpha) Orientální oblasti a nové objevy v morfologii nových taxonů
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...Infrařád Enicocephalomorpha je bazální skupinou ploštic, sesterskou skupinou všech zbývajících Heteroptera (= Euheteroptera) (ŠTYS 1989). Infrařád, jehož unikátní fylogenetické zařazení bylo rozpoznáno většinou moderních autorů (ŠTYS & KERZHNER 1975), je v současné době členěn na dvě čeledi - Aenictopecheidae a Enicocephalidae. V předložené dizertační práci jsou popsány některé nové taxony infrařádu Enicocephalomorpha (Výsledky: Části A-H), přičemž byla zvláštní pozornost věnována nově objeveným, nebo dosud přehlíženým morfologickým znakům této málo známé skupiny, případně znakům, důležitým pro celý řád Heteroptera. V Části A je popsán první zástupce široce rozšířeného rodu Systelloderes z Orientální oblasti, S. loebli Štys & Baňař, 2007 a byl stanoven termín neopatella pro sklerity mezi přední holení a stehnem. Xenicocephalus josifovi Štys & Baňař, 2008, který je popsán v Části B, reprezentuje první známý kompletní exemplář tohoto zvláštního rodu. Byl u něho popsán nový typ loupeživé přední nohy, unikátní v rámci celého infrařádu Enicocephalomorpha. V práci je diskutována potenciální potravní specializace tohoto druhu. Nový rod Phaenicocleus Štys & Baňař, 2009, stanovený pro tři druhy, všechny známé pouze podle jednoho samce, je popsán ze severního Bornea v Části C.

The first unique-headed bug (Hemiptera, Enicocephalomorpha) from Cretaceous Iberian amber, and the Gondwanan connections of its palaeoentomological fauna
Enicocephalomorpha, also known as unique-headed bugs, are a seldom-collected infraorder of heteropteran insects whose evolutionary relationships have puzzled entomologists for more than a century. Unique-headed bugs are exceptionally rare in the fossil record, which hinders our understanding of the morphological transformations of the lineage across time and also affects the calibration of molecular clock estimates used to date the origins of the infraorder. Here, we report the discovery of Enicocephalinus ibericus sp. nov. from Iberian amber in the Ariño deposit in Spain, early Albian (Early Cretaceous) in age. The new species represents the second oldest fossil enicocephalomorphan to date, and the second record of this infraorder from European deposits. Remarkably, the closest relative of E. ibericus is the congeneric E. acragrimaldii Azar from Lebanese amber that is c. 20 myr older (Barremian), indicating a long-term persistence of the Enicocephalinus lineage across geological time. A review of the existing literature enabled us to record a total of 20 congeneric insect species that have been found in both Lebanese and Iberian ambers, suggesting the existence of previously underappreciated entomofaunal connections between southern Laurasia (the European archipelago) and northern Gondwana during the Cretaceous. We show that the palaeoentomological record holds remarkable potential for elucidating the faunistic exchanges and palaeobiogeographical patterns in the peri-Tethyan region during the Cretaceous

A new Xenicocephalus species from Ecuador (Heteroptera, Enicocephalomorpha, Enicocephalidae)
Xenicocephalus tomhenryi sp. n. (Insecta: Hemiptera: Heteroptera: Enicocephalomorpha: Enicocephalidae) is established for a single macropterous female from Ecuador. The enigmatic genus now includes three species known from only two Neotropical adults and an incomplete female specimen. The new species is described and illustrated, extensive comparative diagnoses for Xenicocephalus species are provided, and nomenclature, distribution, and biology of the genus are reviewed. The architecture of the raptorial forelegs of Xenicocephalus is unique among Enicocephalomorpha, and the genus is classified as subfamily incertae sedis

The latter kind of setae occurring all over tarsus. Mid - and hindtibiae with a long diagonal vestiture all over, setae longer than tibial diameters; the same true for mid - and hindtarsi. The setae of dorsal and ventral tibial faces thin, trichobothrium-like (?). Abdomen. Margin without specialized setae, uniformly covered with uniformly curved setae becoming gradually longer posteriad, longest all along edge of segments 7 and particularly 8; the latter posteriorly with 3 + 3 very long setae, the longest exceeding apex of pygophore.

Longitudinal (anterior) tibial depression starting at the points of tibial dilatation and running up to the cleaning comb. (Foretarsus pressed to the distal edge of tibia on both forelegs - consequently, apicitibial and tarsal armatures could not have been studied). Inner (anterior) claw large, posterior one represented by a short rounded hump only. Mid - and hindtibiae with two apical bristle combs each; claws nearly isomorphic (the inner (anterior one) slightly longer. Abdomen.
