Revision of the plant bug genus Cylapocoris Carvalho (Hemiptera: Heteroptera: Miridae: Cylapinae), with descriptions of seven new species from Costa Rica, Brazil, Ecuador, and Venezuela

Revisiting the Taxonomy of Cylapocoris Carvalho, 1954 (Hemiptera: Miridae: Cylapinae) with Descriptions of Five New Species and Morphology-Based Phylogenetic Analysis of the Genus

This paper provides descriptions of five new species of the Neotropical genus Cylapocoris Carvalho, 1954 (C. bimaculatus n. sp., C. brooksi n. sp., C. carvalhoi n. sp., C. scutellatus n. sp., and C. simplexoides n. sp.). Cylapocoris and Cylapocoroides Carvalho, 1989 are redescribed and rediagnosed. Illustrations of male genitalia, scanning electron micrographs of selected structures of certain taxa, and an identification key to species are provided. Female genitalia are described and illustrated for the first time for Cylapocoris in nine out of 19 known species. A cladistic analysis of the genus, based on 62 morphological characters, is presented as a contribution to the understanding of relationships within Cylapocoris and its relationships with other groups of Cylapinae. The analysis comprises 16 ingroup species and 15 outgroup taxa. Both equal and implied weighting parsimony analyses were used in the phylogenetic reconstruction. We confirm the monophyly of Cylapocoris and its sister-group relationship with Cylapocoroides. Additionally, we identify subgroupings within Cylapocoris. Intertribal relationships within Cylapinae are briefly discussed.

Sulawesifulvius thailandicus - a new species of the genus Sulawesifulvius Gorczyca, Chérot & Štys from Thailand (Hemiptera, Heteroptera, Miridae, Cylapinae)

A new species of the genus Sulawesifulvius, Sulawesifulviusthailandicus Wolski, Yasunaga & Gorczyca, sp. n., is described from Thailand. The present finding also represents the first distribution record in Indochina for the genus. Color adult habitus images for Sulawesifulviusthailandicus and Sulawesifulviusschuhi (type species of the genus), male genital drawings of Sulawesifulviusthailandicus, and scanning electron micrographs of selected structures of Sulawesifulviusschuhi and Sulawesifulviusthailandicus are provided.

Revision of the plant bug genus Xenocylapidius (Hemiptera, Heteroptera, Miridae, Cylapinae), with descriptions of five new species from Australia and New Caledonia

The genus Xenocylapidius Gorczyca, 1997 is revised. Five new species: Xenocylapidiusacutipennissp. n., Xenocylapidiusatersp. n., Xenocylapidiusbimaculatussp. n., Xenocylapidiusgemellussp. n., and Xenocylapidiusrolandisp. n. are described from Australia and New Caledonia. Illustrations of the male genitalia, color photographs of dorsal and lateral views of the adults of all species, and key to species of the genus Xenocylapidius are provided.
