Review of present knowledge of the external male and female genitalia in Pyrrhocoroidea (Heteroptera)
Mazáčková, Nikola ; Kment, Petr (advisor) ; Baňař, Petr (referee)
Superfamily Pyrrhocoroidea with its about 670 species in 71 genera is one of the smaller groups within the true bugs (Hemiptera: Heteroptera: Pentatomomorpha). The common characteristics for these bugs are aposematic coloration and absence of ocelli. Most of the species are phytophagous and some are of economic importance as cotton stainers. The superfamily is further subdivided into two families, Pyrrhocoridae and Largidae, whose phylogenetic relatioships have been a subject of only few studies so far. To help resolve this problem, both molecular and morphological phylogenetic studies are needed. Among the morphological characters of importance are external genitalia of both sexes. This thesis gives a short overview of the current phylogeny of Pyrrhocoroidea. Its main focus is on the morphology of external male and female genitalia, which is summarized and characterized for each genus, and points out some essential differences between the taxa. A table uniting terms used for the particular structures of genitalia by different authors is included.
