Three closely related species of phyline plant bugs are unique in the diverse family Miridae because of their remarkable antennae; the third (or second and third) flagellomere is enlarged and bears erect, dark, scalelike setae. Host plants for two of the species—Hambletoniola antennata Carvalho and Larinocerus balius Froeschner—have been known, but no host information has been available for L. personatus (Knight). Escobilla butterflybush, Buddleja scordioides Kunth (Scrophulariaceae), is newly recorded as the host of L. personatus in western (Trans-Pecos) Texas, and new Texas records are given for this seldom-collected mirid. New distribution records also are given for H. antennata in western Texas, in addition to its occurrence on ceniza, Leucophyllum frutescens (Berl.) I.M. Johnston (Scrophulariaceae). Scanning electron micrographs of the antennal setae of L. personatus are provided; included for both mirid species are color photographs of their host plants and an adult on host foliage.
