Ischnodemus pilcomayo, a New Species from Argentina, and Description of the Male of I. pullus Slater and Wilcox (Hemiptera: Heteroptera: Blissidae)

PABLO M. DELLAPÉ — 2025-10-31

A new species of the cosmopolitan genus Ischnodemus, I. pilcomayo, new species from the Rio Pilcomayo National Park, Formosa Province, Argentina, and the male of Ischnodemus pullus Slater and Wilcox, 1969 are described, including dorsal and lateral habitus and male genitalia images. Photographs of the female holotype of I. pullus and the macropterous male holotype of Reticulatodemus nitidus Slater and Wilcox, 1966 are given, together with dorsal and lateral habitus images of the brachypterous form of the latter species.

**An Apterous Specimen of Guithera feana Distant (Reduviidae: Emesinae: Leistarchini) from Karnataka, India**

HEMANT V. GHATE — 2025-10-31

A relatively poorly known emesine bug, Guithera feana (Distant, 1903), was recently discovered in Karnataka, India. The original description of this species is based on a macropterous specimen collected from Burma (=Myanmar) and subsequently macropterous specimens were also collected from Siam (=Thailand) and from South India. This study presents the first illustrated description of an apterous male collected from Karnataka State, India.

Corrections to Some Recently Published Papers on Heteroptera (Hemiptera) II

PETR KMENT — 2025-10-31

We provide corrections to 19 recent papers (published since 2007) as well as one older paper from 1973. Two new subjective synonyms are proposed: Picromerus orientalis Rishi and Abbasi, 1973, new synonymy = P. griseus (Dallas, 1851) and Piezodorus brevis Hassan, Shree and Kumar, 2025, new synonymy = Piezodorus hybneri (Gmelin, 1790). The following species must be excluded from the faunal lists of the particular countries due to obvious misidentifications: Neottiglossa lineolata (Herrich-Schäffer, 1830), Podops inunctus (Fabricius, 1775) and Tarisa pallescens Jakovlev, 1871 (all Pentatomidae) from Greece; Astacops occidentalis Distant, 1903 and Graptostethus nigriceps Stål, 1874 (both Lygaeidae) and Halyomorpha halys (Stål, 1855) (Pentatomidae) from India; Macrovelia hornii (Uhler, 1872) (Macroveliidae), Deraeocoris ruber (Linnaeus, 1758) and Orthotylus caprai Wagner, 1955 (both Miridae) from Iraq; Gminatus australis (Erichson, 1842) (Reduviidae), Arocatus longiceps Stål, 1872 (Lygaeidae), Geocoris punctipes (Say, 1832) (Geocoridae), Hypselonotus punctiventris Stål, 1862 (Coreidae), Neottiglossa undata (Say, 1832) and Piezodorus lituratus (Fabricius, 1794) (both Pentatomidae) from Pakistan. The record of Arhaphe deviatica Brailovsky, 1981 (Largidae) from Saudi Arabia is rejected due to lack of evidence. The records of Physopelta gutta gutta (Burmeister, 1834) (Largidae) from Iran and Geocoris amabilis Stål, 1855 from the Canary Islands are problematic and require confirmation. The following new records are provided here: Graptostethus nigriceps from the Solomon Islands, Gyndes pallicornis (Dallas, 1852) from Thailand, and Psacasta neglecta (Herrich-Schäffer, 1837) (Scutelleridae) from Greece. The distribution of Stephanitis oschanini Vasiliev, 1935 and Stephanitis pyri (Fabricius, 1775) (Tingidae) is discussed and their identification characters are illustrated.

**Redescription of Spartocera granulata Stål, 1870 (Hemiptera: Heteroptera: Coreidae) and Notes on Its Natural History in Costa Rica**

ANDREY J. PERAZA-SÁNCHEZ — 2025-10-31

The coreid Spartocera granulata Stål, 1870, is redescribed, providing detailed photographs of adults and genitalia of both sexes for the first time. Images of the type specimen are also provided. Furthermore, the life cycle of this leaf-footed bug, closely associated with plants in the family Convolvulaceae—specifically the genus Ipomoea Linnaeus, 1753—is documented. The eggs and all nymphal stages are described for the first time, accompanied by detailed figures and data on behavior, distribution, seasonality, and host plants.

A New Genus and Species of the Mirid Subfamily Isometopinae (Hemiptera: Heteroptera: Miridae) from Japan, with a Key, Checklist, and New Synonymy for the Japanese Fauna

TOMOHIDE YASUNAGA — 2025-10-31

A unique isometopine plant bug species representing a new genus, Reometopus kijimura new genus and new species (provisionally belonging to the tribe Myiommini), is described from Okinawa Island, Japan. Paloniella parallela Yasunaga and Hayashi, 2002, is proposed to be synonymized with Isometopus hasegawai Miyamoto, 1965. The Japanese fauna of the subfamily Isometopinae is accordingly updated, and an annotated checklist and a key to genera and species are provided.
