Comments. The specimens examined in this study are from a site near the type locality and an additional site in Dallas County near the site where paratypes were collected ( Poulton & Stewart 1991). The major difference in males of this species and L. szczytkoi is in the tergal lobes of segment 8 ( Figs. 50 , 56 ).
