Le Genre Xylocoris: Subdivision et Espèces Nouvelles [Hem. Anthocoridae]

Le Genre Xylocoris: Subdivision et Espèces Nouvelles [Hem. Anthocoridae] SUMMARY J. Carayon: The genus Xylocoris: subdivision and new species. The characters used until now for the subdivision of the genus Xylocoris are almost worthless. New charcters are pointed out; the most important seem in the position, on the abdomen of the ♀♀, of the « traumatic copulation site », and the presence or absence at this place of an ectospermalege. Use of these caracters leads to the following subdivision, further confirmed by other caracters given, especially by the tibial teeth of the ♂♂. — Copulation site behind { ectospermalege absent.‥ Subg. Stictosynechia right margin { ectospermalege present ‥ nominal subg. Xylocoris — Copulation site in { ectospermalege absent. ‥ ‥ Subg. Arrostelus antero-dorsal area { Ectospermalege present ‥ Subg. Proxylocoris nov. The two sites of traumatic copulation seem to correspond to two large evolutionary lines, where the species with a spermalege arise from species without spermalege. The main taxonomical data brought by the study of each subgenus are: — New subgenus: Proxylocoris; — New species: X. (Proxylocoris) cacti [Mexique]; X. (Proxylocoris) confusus [Afrique tropicale]; X. (Proxylocoris) nigromarginatus [Maroc]; — New subgeneric combinations: X. afer (Reuter), X. clarus (Distant), X. galactinus (Fieber) and X. jeanneli (Popp.) in subg. Proxylocoris; X. congoensis (Bergr.) and X. hirsutus Cara, in subg. Arrostelus. — Exclusion of X. machadoi (Carv.) from Xylocorini and inclusion of this species, which represents a new genus, in Almeidini. — New synonymies: X. congoensis Bergroth [= Piezostethus pallidipes (Poppius), = Xylocoris antaoensis Wagner]. The use of new specific characters allows to correct the confusions which are often done between some already described species of subg.

Abstract

SUMMARY J. Carayon: The genus Xylocoris: subdivision and new species. The characters used until now for the subdivision of the genus Xylocoris are almost worthless. New charcters are pointed out; the most important seem in the position, on the abdomen of the ♀♀, of the « traumatic copulation site », and the presence or absence at this place of an ectospermalege. Use of these caracters leads to the following subdivision, further confirmed by other caracters given, especially by the tibial teeth of the ♂♂. — Copulation site behind { ectospermalege absent.‥ Subg. Stictosynechia right margin { ectospermalege present ‥ nominal subg. Xylocoris — Copulation site in { ectospermalege absent. ‥ ‥ Subg. Arrostelus antero-dorsal area { Ectospermalege present ‥ Subg. Proxylocoris nov. The two sites of traumatic copulation seem to correspond to two large evolutionary lines, where the species with a spermalege arise from species without spermalege. The main taxonomical data brought by the study of each subgenus are: — New subgenus: Proxylocoris; — New species: X. (Proxylocoris) cacti [Mexique]; X. (Proxylocoris) confusus [Afrique tropicale]; X. (Proxylocoris) nigromarginatus [Maroc]; — New subgeneric combinations: X. afer (Reuter), X. clarus (Distant), X. galactinus (Fieber) and X. jeanneli (Popp.) in subg. Proxylocoris; X. congoensis (Bergr.) and X. hirsutus Cara, in subg. Arrostelus. — Exclusion of X. machadoi (Carv.) from Xylocorini and inclusion of this species, which represents a new genus, in Almeidini. — New synonymies: X. congoensis Bergroth [= Piezostethus pallidipes (Poppius), = Xylocoris antaoensis Wagner]. The use of new specific characters allows to correct the confusions which are often done between some already described species of subg. Proxylocoris.
