**Three Morphological Groups of South American Geocoris Fallén, Five New Species and Key to Species Belonging to the “flavilineus” Group (Hemiptera: Heteroptera: Lygaeoidea: Geocoridae)**

2025-01-31T20:32:57+13:00

The known South American species of the genus Geocoris Fallén are here divided into three morphological groups: “flavilineus” group with 7 species, “punctipes” group with 9 species, and “thoracicus” group with 3 species. Each group is characterized and the species belonging to each one listed. The “flavilineus” group is revised, including the description of five new species, and a key to included species provided.

**Life Cycle of Hadronema militare Uhler (Hemiptera: Heteroptera: Miridae)**

2025-01-31T20:32:47+13:00

Lupine (Lupinus L.) and goldenbanner (Thermopsis R. Br.), herbaceous legumes (Fabaceae) in the subfamily Faboideae, are plants that support the nymphal development of the orthotyline plant bug Hadronema militare Uhler. In Wyoming, H. militare is univoltine, overwinters as eggs, and completes nymphal development, reproduction, and oviposition before mid-summer host senescence. At a mid-elevation (1675 m amsl) study site in 2024, overwintering eggs hatched in late April, coincident with initiation of active growth of the host Thermopsis rhombifolia (Nutt. ex Pursh) Nutt. ex Richardson. Nymphs developed in the litter under the host throughout May. In mid-May, the first adults were observed in the litter feeding on host plants. Mating began in early June, and oviposition occurred in the host’s stems a few days after mating. Adults persisted at the site until host senescence in early July. The eggs and nymphs are described, and a new state record for Nebraska is provided. Other legume hosts at a low-elevation site in Nebraska (Lupinus argenteus Pursh) and a higher-elevation site in Wyoming (L. argenteus and T. divaricarpa A. Nelson) are noted.

A Catalogue of the Subfamily Mirinae (Insecta: Hemiptera: Heteroptera: Miridae) of Vietnam

2025-01-31T20:32:50+13:00

This paper provides the first annotated catalogue of the plant bug subfamily Mirinae (Heteroptera: Miridae) from Vietnam. A total of four tribes, 30 genera, and 39 species are recognized and catalogued. For each species, brief information is provided on its distribution, host plant and dorsal habitus.

Review of the Fungal-Inhabiting Plant Bugs of the Subfamily Cylapinae in Japan (Heteroptera: Miridae), with Descriptions of a New Genus and Three New Species

2025-01-31T20:32:53+13:00

The Japanese fauna of the plant bug subfamily Cylapinae is reviewed and updated. Based on recently accumulated cylapine specimens from southwestern Japan including the Ryukyus, the following new genus and new species have been established and are herein described: Wolskicoris Yasunaga, new genus; Fulvius reoi Yasunaga and Wolski, new species; Peritropis akitai Yasunaga and Wolski, new species; and Wolskicoris quadrinotatus Yasunaga and Wolski, new species. Two known species, Fulvius niveonotatus Yasunaga, 2000 and Yamatofulvius sinuicornis Yasunaga, 2000, are herein transferred to Wolskicoris new genus and Rhinocylapidius Poppius, 1915, respectively. Two new combinations, W. niveonotatus (Yasunaga), new combination and R. sinuicornis (Yasunaga), new combination are accordingly proposed. An updated checklist and key to tribes, genera, and species are provided to aid in the identification of the Japanese Cylapinae. A teratological antennomere found in a new species, Peritropis akitai, is also documented.
