In this contribution, we provide diagnoses, redescriptions, and habitus images of the type species of the 23 known genera of New World Blissidae (Hemiptera: Heteroptera: Lygaeoidea); and describe three new genera: Brailovskyodemus, new genus to accommodate four species transferred from Extarademus [B. bifida (Slater and Brailovsky, 1990), new combination, and B. indomita (Slater and Brailovsksy, 1995), new combination] and Patritiodemus [B. clavatus (Slater and Ahmad, 1971), new combination (type species); and B. nigellus (Slater and Ahmad, 1971), new combination]; Metafemorademus, new genus, for two species transferred from Extarademus [M. mundus (Slater and Wilcox, 1966), new combination (type species); and E. prunimundus (Slater and Brailovsky, 1990), new combination]; and Prosternademus, new genus, for one species transferred from Extarademus [P. humerus (Slater and Wilcox, 1966), new combination (type species)]. In addition, we synonymize Patritiodemus Slater and Ahmad, new synonymy, with Ischnodemus Fieber, transferring the species with mutic fore femora to Ischnodemus [I. brusai (Dellapé and Montemayor, 2009), revised combination; I. dilutipes Stål, 1860, revised combination; I. minutus (Slater and Ahmad), new combination; I. singularis (Slater and Ahmad, 1971), new combination; and I. unicoloris (Slater and Ahmad, 1971), new combination] and the species with spined fore femora to Extarademus [E. albomaculatus (Slater and Ahmad, 1971), new combination; and E. delicatus (Slater and Wilcox, 1968), new combination]; and transfer five species of Patritius Distant to Riggiella Kormilev [R. alternatus (Slater and Wilcox, 1966), new combination; R. colombianus (Slater and Wilcox, 1966), new combination; R. cubensis (Barber, 1947), new combination; R. englemanni (Slater, 1979b), new combination; and R. osuna (Slater and Brailovsky, 1995), new combination]. Finally, we provide a phylogenetic analysis of the 11 New World genera having closed fore coxal cavities, based on 52 taxa (including outgroup) and 44 characters, resulting in six trees supporting the monophyly of most of the genera, and a revised key to facilitate recognition of the genera.

The Saucer Bugs (Hemiptera: Heteroptera: Naucoridae) of French Guiana

Northeastern South America has been historically undersampled across most biota. Surveys conducted for aquatic insects in French Guiana during the past 14 years have resulted in the collection of 16 species of Naucoridae, of which 10 are new country records. Of these 16 species, 10 are in the subfamily Ambrysinae, one in Ilyocorinae, and five in Limnocorinae. At least six of these species are considered rare, as very few specimens are known. A checklist, annotated list, distribution maps, and an illustrated key to identify adults of these species are presented.

**Two New Species of Tagalis Stål (Heteroptera: Reduviidae: Emesinae: Saicini) from Panama and Brazil, with an Analysis of the Male Genitalia Morphology**

Valentina Castro-Huertas, María Cecilia Melo — Wed, 31 Jan 2024 00:00:00 +1300

Tagalis matamorosae n. species and Tagalis pagu n. species are described from specimens collected in Barro Colorado (Panama) and Rio Grande do Sul (Brazil), respectively. Among the species of Tagalis, both new species have coloration patterns and genital structure particularly different. Tagalis matamorosae n. species is the unique species with a gonoplac composed by a pair of sclerites, and T. pagu n. species shows the posteromedial process of pygophore with a curvature exclusive within the genus. Digital images of external morphological characters and of the genitalia are provided. To facilitate the identification of the new species, an updated key to the species of Tagalis is presented. Male genital structures along the genus and its taxonomic and phylogenetic implications are discussed.

**Life Cycle of the Phyline Plant Bug Conostethus americanus Knight, 1939 (Hemiptera: Heteroptera: Miridae) in Native Mixed-Grass Prairie in Wyoming, USA**

The life cycle of the phyline plant bug Conostethus americanus Knight 1939 (Hemiptera: Heteroptera: Miridae: Phylinae) is described from native mixed-grass prairie in southeast Wyoming. The bug is monophagous, univoltine, and overwinters as eggs in tufts of its host, Sandberg bluegrass (Poa secunda J. Presl, Poaceae). Eggs are laid in the host’s leaf sheaths and occasionally along the rib of wilted leaves. The eggs hatch in April, coinciding with the host’s first spring leaf growth. During the daytime, older nymphs (instars III–V) and recently molted adults are typically found on bare ground, adjacent to the host tuft crowns. After dark, the nymphs and recently molted adults climb onto the leaves to feed. The first adults appear in early May. Males outnumber females 1.5:1. Mating and oviposition occur during the latter half of May and early June. The distribution of C. americanus and its host are mapped. Seasonality is described. Host specificity and habitat affinity, which prevent competition with the ubiquitous Labops hesperius (Hemiptera: Heteroptera: Miridae), are discussed. Photographs of adults, eggs, nymphs, host feeding damage, and habitat are provided.
