Diagnosis. See Hoebeke (1988 (as Th. lira   ), and 1994 (as Th. paralira   )).

Discussion. According to Hoebeke (1994), Th. paralira   differs from Th. lira   only in having a smaller body size, shorter teeth at the posterior margin of the male abdominal tergum 8, and a weaker medial swelling in the posterior half of the tergum. My examination of the types of both species confirmed that they are identical in the shape of the aedeagus. In one paratype of Th. paralira   and in several specimens fitting the description of Th. lira   (in details of the male tergum 8) the internal sac was everted, and rather elaborate sclerites of the internal sac ( Figs. 133–134 View FIGURES 133–134 ) were examined. No difference between the specimens was found. Within species, the shape of the aedeagus and the sclerites of internal sac are usually less variable than the shape of the male tergum 8. It is a common phenomenon in many groups of aleocharines for smaller male specimens to have less prominent secondary sexual features (e. g., in Stethusa dichroa ( Gravenhorst, 1802)   (cf. Figs. 24–26 View FIGURES 23–30 in Gusarov 2003d); in Tropimenelytron americanum Gusarov, 2002e   and Tr. californicum Gusarov, 2002e   ( Gusarov 2002e)). Considering that 1) the types of Th. lira   and Th. paralira   are identical in the shape of the aedeagus; 2) there is no gap between the male specimens with the sexual features fitting Th. lira   on one side, and Th. paralira   on the other ( Figs. 127–132 View FIGURES 127–132 ); 3) it is the smaller male specimens of Thamiaraea   that have less pronounced sexual features on the tergum 8; 4) both morphs are sympatric and even were collected in the same samples ( Hoebeke 1994); I synonymize Th. lira   and Th. paralira   .

My examination of the lectotype of Sableta brittoni   revealed that it in fact belongs to Thamiaraea   and is conspecific with both Th. lira   and Th. paralira   . Thamiaraea brittoni   is the valid name for this species. Unfortunately, Casey (1911a) misplaced this species in Sableta Casey, 1910a   , a genus unrelated to Thamiaraea   , and when Hoebeke (1988) published his review of Thamiaraea   , he had no means of knowing that one species of Thamiaraea   had already been described by Casey.

Distribution. Thamiaraea brittoni   is widely distributed in the eastern United States and Canada. It is known from Ontario, Québec, Connecticut, New York, New Jersey, Pennsylvania, Ohio, Wisconsin ( Hoebeke 1994), Kansas, North Carolina ( Hoebeke 1994) and Mississippi.
