**Review of the Newly Established amictus-Subgroup of the Genus Leptocoris (Hemiptera: Heteroptera: Rhopalidae), with the Description of a New Species from the Arabian Peninsula**

2024-04-30T14:46:37+12:00

Leptocoris arabicus new species (Hemiptera: Heteroptera: Rhopalidae: Serinethinae) is described based on 55 specimens of both sexes collected in various localities of southern Oman and southeastern Yemen; a hypothesis is proposed as to its host plant. The new species is close to Leptocoris amictus Germar, 1838 and to Leptocoris ruber Göllner-Scheiding, 1980, new status, due to the presence of a produced horned process along the posterior ventral margin of the genital capsule. It is distinguished from both by differences in colour pattern and morphology. An informal L. amictus species-subgroup is proposed to accommodate these three species within the Leptocoris hexophthalmus species-group sensu Göllner-Scheiding (1980). The following new faunistic records are also provided: L. amictus from Ethiopia, Mozambique and Zambia; L. ruber from Central African Republic. The occurrence of L. chevreuxi (Noualhier, 1893) in Oman is confirmed. The list of all available species-group names assigned to Leptocoris Hahn, 1833 (gender masculine) and their synonyms is compiled and the gender agreement is corrected in the species names when appropriate. The nomenclatural problem concerning Leptocoris living on Marshall Islands discovered by Kerzhner (2003) is discussed and the following corrections are provided: Leptocoris rufus rufus Hahn, 1833, new status = Leptocoris lariversi Usinger, 1952, new synonymy, and Leptocoris rufus isolatus (Distant, 1914) new status.

Descriptions of Four New Western Hemisphere Palm Bugs (Heteroptera: Thaumastocoridae: Xylastodorinae): A New Species of Xylastodoris from Haiti and Two Remarkable New Genera, One with Two New Species from Ecuador, and One with A New Species from Peru

2024-04-30T14:48:22+12:00

Four new Western Hemisphere xylastodorine palm bugs (Thaumastocoridae: Xylastodorinae) are recognized. Neolatebracoris new genus is described to accommodate Neolatebracoris erwini new species from Peru; Xylastodoris cornutus new species is described from specimens intercepted at Miami, Florida, from Haiti; and Xylastotylus new genus is described to accommodate Xylastotylus emarginatus new species (as the type species) and X. minutus new species from Ecuador. Dorsal and lateral habitus and available genital capsule images, diagnoses, and descriptions are provided for each new genus and species. Relationships and biogeography of the new taxa are discussed, and revised keys to the New World genera of the subfamily and the species of Xylastodoris and Xylastotylus are provided.

**Taxonomic Review of the Genus Eurypharsa Stål (Hemiptera: Heteroptera: Tingidae)**

2024-04-30T14:46:34+12:00

The genus Eurypharsa Stål 1873 is reviewed. Tingis circumdata Blanchard 1842 [not 1847] has priority over Tingis nobilis Guérin-Méneville 1844 and is transferred to Eurypharsa. Eurypharsa phyllophila Drake 1922 is subjectively synonymized with Eurypharsa circumdata [new combination, revised status]. Herein we designate lectotypes for Tingis circumdata and Eurypharsa quadrifenestrata Bergroth 1898, present the first identification key to the species of Eurypharsa, and provide differential diagnoses for all known species. We also report Eurypharsa championi Bergroth 1922, from Bolivia, E. circumdata from Costa Rica and Trinidad, and E. fenestrata Champion 1898a, from Costa Rica and Ecuador for the first time.
