Leptobasis costalimai: Santos (1957: 1) ; Davies & Tobin (1984: 7); Bridges (1994: VII. 59); Garrison (1991: 13); Tsuda (2000: 38); Costa & Oldrini (2005: 8); Lencioni (2006: 155).

Specimens examined: Holotype (3) and Allotype (Ƥ): BRAZIL, Espirito Santo State, Conceição da Barra (18 º 35´S, 39 º 45´W), X- 1944 (Ribeirão do Engano, a small and shallow river, 4–5 meters wide), N.D. Santos leg. ( MNRJ). Paratypes: 20 3, 8 Ƥ same data as holotype. Other specimens: Rio de Janeiro State, São Vicente, flooded area of the São João River, 16 -IX- 1978, Santos leg.: 29 3, 6 Ƥ; 7 -VIII- 1980, 20 3, 25 Ƥ, Santos & Mesquita leg. ( MNRJ); Minas Gerais State, Rio Doce State Park 11, 13 -XII- 1980 (35 3 2 Ƥ), data Pereira & Vulcano leg. ( ABMM). Total 104 3, 42 Ƥ.

Distribution. BRAZIL, States of Rio de Janeiro, Minas Gerais, and Espírito Santo.

Remarks. T. costalimai can be easily identified by its large size (abdomen 32–34; HW 19–20), male mesepisternal tubercle adjacent to mid-dorsal carina ( Fig. 27 View FIGURES 25 – 34 ), and ventral process of male cercus curved and directed ventro-medially ( Fig. 62 View FIGURES 57 – 65 ). The description of male and female by Santos (1957) is adequate, and I provide here new illustrations of cerci ( Figs 60–62 View FIGURES 57 – 65 ) and thorax ( Figs 27–28 View FIGURES 25 – 34 , 101 a). Santos (1957) stated that female thorax does not have the dorsal prominences described for male. Although considerably smaller than in males, tubercles could be detected in all 20 females I examined including the allotype and eight specimens of the type series. In ten specimens (50 %) tubercles were well-developed, in six (30 %) very small, and in four (20 %) poorly-defined. Since in all specimens of the female type series examined by Santos (1957) mesepisternal tubercles could be distinguished it becomes evident that he overlooked these tubercles, certainly much less conspicuous than the "prominences" he had described in the males. In seven females (35 %) tubercles were connected with mid-dorsal carina and in 15 (75 %) posterior margin of mesostigmal plates curved back and penetrated between tubercle of mesostigmal plate and mesepisternal tubercle ( Fig. 48 View FIGURES 47 – 54 ).
