Leptobasis mammilaris Calvert (1909: 201) ; Davies & Tobin (1984: 71); De Marmels (1990: 337, 1992: 63); Garrison (1991: 1); Bridges (1994: 59); Tsuda (2000: 38); Belle (2002: 3) Lencioni (2006: 157).

Specimen examined. 1 3: VENEZUELA, Bolívar State, Uruyen-Aux-antepui (5º52´N, 62º20´W), 14-IV- 1956, Fernandez leg., De Marmels & Garrison det. (MIZA).

Distribution. Brazil, Venezuela, and Suriname.

Remarks. T. mammilaris was described by Calvert (1909) based on a complete male and parts of a second male from Chapada in Mato Grosso State, Brazil, and a single female from Rio de Janeiro. The description is good with simple illustrations of male appendages and thorax and female hind prothoracic lobe. Recently R.W. Garrison studied the complete male syntype from CMNH and provided good illustrations of the main structural characters which were reproduced in Lencioni (2006) and are also included here. De Marmels (1992) recorded a male and a female of T. mammilaris from Venezuela and his identification of the male was confirmed by R.W. Garrison by direct comparison with the complete male syntype. De Marmels (1992) illustrated hind prothoracic lobe of the female from Venezuela, which is completely different from the one illustrated by Calvert (1909, Fig. 117) for the syntype female from Rio de Janeiro. In view of this, De Marmels (1992) concluded that the true female of T. mammilaris is that from Venezuela. R. W. Garrison has examined Calvert´s syntype female labeled as L. mammilaris and has identified it as belonging to Leptobasis sensu stricto. In order to clarify application of the name, I designate the complete syntype male from Brazil, Chapada, H.H. Smith leg. (CMNH) illustrated by Calvert (1909, Figs. 112, 113, 115, 116) and by R.W. Garrison ( Figs 24 , 78–80 , 91 ) as lectotype.

The description of Calvert (1909) does not mention the presence of pale postocular spots and R.W. Garrison (in litt.) confirmed that there are lacking in the lectotype. The male from Venezuela differs from the lectotype by having pale postocular spots that are present also in females, meaning that this character is variable in T. mammilaris .
