ABSTRACT. A new species: Peritropis bicolor is described from New Caledonia with illustrations of pictures of aedeagus, parameres, head and pronotum; two new species of Xenocylapidius: X. gressitti and X. australis are described; new data on a male of Xenocylapidius tamasi GORCZYCA and figures of its parameres and aedeagus are presented. The key to the species of Xenocylapidius is provided.
Key words: Heteroptera, Miridae, Cylapinae, new species, taxonomy, entomology, Peritropis, Xenocylapidius.
INTRODUCTIONTwo species of Peritropis UHLER were known so far from New Caledonia and the Loyalty Islands (GORCZYCA 1997a, 1998). The genus Xenocylapidius was described (GORCZYCA 1997b) on the basis of a single female collected in New Caledonia and deposited at the Hungarian Museum of Natural History.
Among the material collected in New Caledonia which I received from the Department of Entomology Collection, Bernice P. Bishop Museum, Honolulu, USA, I found two male specimens which represented a new species of Peritropis.
I also found a few specimens, males and females of a recently described Xenocylapidius tamasi GORCZYCA (GORCZYCA 1997b), which allowed me to complete the description of the species, as well as a female which represented a new species of the genus. I also received a female specimen collected in Australia, 14 JACEK GORCZYCA which represented another new species of Xenocylapidius. The descriptions of the new species, the redescription of the Xenocylapidius tamasi and first data on the male of X. tamasi as well as the key to the species of Xenocylapidius are given below.
ACKNOWLEDGEMENTSI would like to express my sincere thanks to Miss Karin KAMI, Dr. Gordon NISHIDA (Department of Entomology Collection, Bernice P. Bishop Museum, Honolulu, HI USA) and Dr. Tamas VÁSÁRHELYI (Hungarian Museum of Natural History, Budapest, Hungary) for the loan of the representatives of Cylapinae.
I would like also to thank Dr. Yuri POPOV (Paleontological Institute, Russian Academy of Sciences, Moscow, Russia), who kindly put the specimen from Australia at my disposal.
