Among the Oriental species, T. brunnea is distinguished by the slightly extended posterior region of sternum IX and its shallow mesal excavation. The inferior appendage is subrectangular in lateral view, perhaps most similar to that of T. udagama , new species, but in the later species the posterior extension of sternum IX is more prominent.

Adult. Length of forewing: male 6.5 mm (n=1), female 6.5 mm (n=1). Color brown.

Male. Abdominal segment IX annular, setose, especially ventrally; in lateral view anterior and posterior margins parallel, shortest at insertion of preanal appendage; tergum IX short, not produced posteriorly; posterior extension of sternum IX short, less than 1/3 length of sternum, in ventral view base narrow, apex excised, overall shape subtriangular, apical margin with shallow, U-shaped excision, apicolateral corners smooth, setose, in lateral view rounded; posterior process of segment IX extended dorsad to form heavily sclerotized projection, surface rugose apicodorsally, in caudal view projection triangular, in lateral view rounded, in ventral view rounded, entire. Preanal appendage oblong, heavily setose, slightly shorter than segment X. Inferior appendage spatulate, setose, apex strongly curved mesad, in lateral view subrectangular, dorsal edge straight, ventral edge shallowly excavated, apicoventral edge slightly irregular, mesolateral surface with small triangular setose process, basoventrally with short, quadrate process bearing apical setae, mesobasally with small, broad, flat process bearing apical setae. Tergum X saddle-shaped, broad, about 1/2 width of segment IX, in lateral view triangular, apex acute, dorsolaterally with pair of short, digitate protuberances, in dorsal view apex rounded. Phallic apparatus short, compact; phallobase tubular, apparently fused with phallicata, basoventrally with short sclerotized flange apparently articulating with base of fused inferior appendages; phallicata strongly down turned apically at nearly 90 degrees to phallobase, apex of phallicata with straight lateral sclerotized flanges and mesal membranous region, dorsolateral corners square, slightly projecting; parameres absent; phallotremal sclerite not discernable.

Female. Segment IX short, in lateral view posterior margin rounded, anteroventral margin indistinct, semimembranous, setose. Tergum X long, almost as long as preanal appendages, in lateral view triangular, apex subacute, in dorsal view subrectangular apically; basolaterally with pair of short papillate processes. Preanal appendage long, digitate, setose. Lamella very large, constricted basally, in lateral view directed ventrad, dorsal margin broadly rounded, ventral margin straight, apex rounded, outer and inner surfaces setose; in ventral view lamella straight, mesal surface concave. Gonopod plate basolateral edges produced in flanges, apex with broad excavation, surface with fine striations. Spermathecal sclerite complex, in ventral view oval, apex subacute, laterally with semimembranous flanges, medially with keyhole-shaped sclerite.
