Speocirolana hardeni, newspecies, is described from Bexar and Val Verde Counties; it issimilar to S. thennydronis, but has longer and more slenderpereopods and uropods.In this paper I add 2 species, one new, to theknown isopod fauna of Texas, and bring up to datethe records of Cirolanides texensis, which nownumber 24.STENASELLIDAE DUDICH, 1924Mexistenasellus Cole & Minckley, 1972Until now North American isopods of the familyStenasellidae have been reported only from Mexico,where 6 species of Mexistenasellus and 2 species ofEtlastenasellus are known to occur (summarized inBowman, 1982b). The northernmost of thesestenasellids has been found recently in southernTexas, as documented below.Mexistenasellus coahuila Cole and Minckley, 1972Figs. 1, 5aMexistenasellus coahuila Cole and Minckley, 1972: 315-320,figs. 1-31; Cole, 1984:8-9.Mexistenasellus sp.: Henry, Lewis, and Magniez, 1986:460.Material.-TEXAS: Bexar County: spring on Ebank of San Antonio River, 23 Oct. 1985 (Scott J.Harden), 2 males, 4 females (USNM 242471); 26Oct. 1985 (Scott J.
