Psyrassa castanea Bates. First larval host record.

This species was formerly known as Psyrassa texana Schaeffer before being synonymized by Toledo (2006). DJH reared one specimen from dead Leucaena pulverulenta (Schltdl.) Benth. (Fabaceae) from TX: Cameron Co., Sabal Palm Sanctuary. Linsley and Chemsak (1997) list Celtis texana Scheele , Fraxinus , and L. pulverulenta as host plants, whereas Hovore et al. (1987) did not list any larval host plants in their comprehensive paper on Cerambycidae from southern Texas. Apparently, Linsley and Chemsak (1997) listed records of plants from which P. castanea was beaten from as cited in Hovore et al. (1987). To the best of our knowledge, our specimen from L. pulverulenta is the first confirmed rearing record of this species. DJH collected numerous specimens at lights and by beating flowering Condalia in early June at Cameron Co., Laguna Atascosa National Wildlife Refuge.
