Interpretive Summary: The true bug family Miridae, commonly referred to as plant bugs, is one of the most important groups of insects. The family contains such notorious crop pests as the tarnished plant bug and the cotton fleahopper. Many other plant bugs, however, are predaceous and may be beneficial in biological control programs. The plant bugs belonging in the genus Hyalochloria seem to be in large part predatory. One South American species is known to prey on cotton leafworm and cotton aphids and another species occurring in Florida is found on a wide variety of plants, suggesting that it is also an opportunistic predator tracking its prey across various unrelated hosts. Presented in this paper is a revision of this plant bug genus, with the description of four species new to science; clarification of two confused species, one of which is found in the United States; the descriptions of previously unknown males for two species; and a akey to the 20 known species of the genus. Illustrations of the male antenn and dorsal photographs are provided for each species. This paper will be of interest to scientists, APHIS, state agricultural workers, and all other researchers working on the biological control of agricultural pests.
The four new species H. apicata, H. bispina, and H. marginatus from Brazil, and H. baranowskii Panama and Trinidad, are described; H. rondoniensis Carvalho is synonymized under H. scutellata Henry; males of H. antilleana Carvalho and H. araripensis Carvalho are described for the first time; confusion pertaining to the identity of H. caviceps and H. unicolor is clarified; a lectotype for H. caviceps Reuter is redesignated; new distribution records are given; and photographs of adults, illustrations of male antennae, and a revised identification key to the 20 known species are provided to facilitate recognition.
