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) 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 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); 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.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; both teacher heads agree on what is shown here.
