Résumé :
The geocorine (Hemiptera: Heteroptera: Lygaeoidea: Geocoridae) true bug genus Umbrageocoris Kóbor, 2019 is redefined based on new morphological information from newly acquired specimens. Two new species are described: U. booneisp. nov. from continental Indomalaya and U. malipatilisp. nov. from Australia; two new combinations are proposed: U. elegantulus (Distant, 1904), comb. nov., and U. woodwardi (Malipatil, 1994), comb. nov. (both transferred from Geocoris Fallén, 1814). Keys, diagnoses, and distribution data to the discussed species are provided. Hypotheses on the origin of Umbrageocoris and its relationship to other geocorine genera in the region are formulated. New country records: U. elegantulus (Papua New Guinea), U. maai maai (Thailand, Laos) and U. woodwardi (Papua New Guinea).

Résumé :
Güneydoğu Anadolu Bölgesi Türkiye’nin en önemli pamuk üretim bölgesi durumunda olup, sulamaya açılan alanların artmasıyla birlikte özellikle son yıllarda bitki koruma sorunlarının çözümü için kimyasal ilaçların bilinçsiz kullanımı zararlı türler ile mücadelede önemli bir yere sahip olan faydalı böcek popülasyonlarını tehlike altına sokmaktadır. Geocoris spp. (Hemiptera: Geocoridae) kırmızıörümcek, thrips, yaprakbiti gibi zararlılar ile beslenebilen etkili bir doğal düşmandır. Diyarbakır, Şanlıurfa ve Mardin illeri pamuk ekim alanlarında 2021 ve 2022 yıllarında toplanan Geocoridae familyasına ait Geocoris türlerinin belirlenmesi amacıyla iki haftalık periyotlarla arazi çıkışları gerçekleştirilerek D-Vac ile örnekleme yapılmıştır. Toplanan örneklerden 2021 yılında 7 tür 2022 yılında ise 6 tür elde edilmiştir. Bu türler Geocoris (Geocoris) megacephalus (Rossi, 1790), Geocoris (Geocoris) punctipes (Say, 1831), Geocoris (Geocoris) pubescens (Jakovlev, 1871), Geocoris (Geocoris) pallidipennis (Costa, 1843), Geocoris (Piocoris) erythrocephalus (Lepeletier & Serville, 1825), Geocoris (Piocoris) putonianus (Bergroth, 1892) ve Geocoris (Geocoris) arenarius (Jakovlev, 1867) olarak tespit edilmiştir.

Résumé :
The validity and necessity of subspecies as a taxonomic category and the implications of the subspecies concept in various taxa of animals is subject of debates since its very existence. In case of the species of the lygaeoid subfamily Geocorinae there are multiple examples of species consisting of up to nine subspecies which were mostly described as varieties or forms before the middle of 20th century, but upgraded to valid subspecies subsequently, usually without providing any arguments. As part of an integrated taxonomic study on the Palaearctic representatives of Geocorinae, the status of the subspecies of Geocoris (Piocoris) erythrocephalus (Lepeletier & Serville, 1825) was revisited. A critical review of the literature available and our studies, involving analysis of COI sequences, morphological examination and distribution data processing with the use of Geographic Information System, concluded that two of the three subspecies, G. e. erythrocephalus and G. e. marginellus Horváth, 1907, can be considered valid, while G. e. litoreus Horváth, 1895, is merely a phenotypically manifested infrasubspecific genetic variety of G. e. erythrocephalus, with no taxonomic value as it was suggested by earlier study of another author. Besides the interpretation of evidence, the applicability of the subspecies concept in Geocorinae is discussed as well.

Résumé :
Geocoris bullatus (Say 1831), (Henriptera: Lygaeidae) has been collected and studied across North America but the present work is the first detailed study of western North American G. discopterus Stål 1874. In fact, it has been claimed that G. discopterus is solely a species of the east. As the two species are taxonomically difficult to separate, when they were apparently discovered together at several localities in the southwestern Yukon, a detailed investigation of their systematics and distribution seemed necessary. Species status of Yukon G. bullatus and G. discopterus was established morphologically using standard taxonomic characters. Biological species status was confirmed through breeding experiments. The life cycles of Yukon G. bullatus and G. discopterus were studied and significant differences were discovered in the generation time and phenology. G. discopterus is univoltine and usually overwinters in the adult stage, while G. bullatus is bivoltine and overwinters in the egg stage. Fat body dissections revealed adult G. discopterus fat body size increased toward the end of summer. No such trend was recognized in adult G. bullatus. Total fatty acid levels were assayed for each species, and adult G. discopterus were found to contain higher quantities than G. bullatus, perhaps correlating with the overwintering strategy in G. discopterus An investigation of the habitats occupied by each species was performed through an in depth vegetation analysis. G. discopterus was found to prefer xeric sites situated on south-facing slopes and outwash plains while G. bullatus occupied disturbed mesic roadsides and wastelands. Habitat preference differences coupled with phenological differences may account for the apparent sympatry of these two Geocoris species at some Yukon localities. Comparison of the xeric habitat of G. discopterus to known glacial relict sites in the interiors of Alaska, Yukon and Siberia reveal striking similarities. Late Pleistocene pollen cores also compare favorably with these G. discopterus habitats. In view of this and the disjunct North American distribution of G. discopterus, this species is hypothesized to be a relict species from the late Pleistocene ice age.
