Type material.
Holotype. Brazil • Female, CNC; Guanabara, Represa Rio Grande; vii.1972; F. H. Oliveira leg.; Voucher code: CNC 1179672.
Diagnostic description.
Anteromesoscutum mostly smooth, with relatively shallow punctures; scutellar disc smooth and shiny, without punctures; T 1 strongly narrowing towards posterior margin (width at anterior margin 1.8 × width at posterior margin), T 1 length 4.5 × its width at posterior margin; T 2 weakly sculptured and trapezoidal, its width at posterior margin 2.5 × its central length; ovipositor sheath 0.9 × metatibia length; all coxae dark brown, all tarsus brown, rest of legs mostly yellow except for metafemur and metatibia with posterior 0.2 brown; body length: 2.83 mm; fore wing length: 2.60 mm. Among species with T 1 not rectangular and T 2 not strongly sculptured, this species is characterized by its strongly narrowing T 1, trapezoidal T 2, all coxae dark brown and ovipositor sheath almost as long as metatibia length.

Etymology.
The second author dedicates this species in honor of Cecilia Escobar of the Smithsonian Institution (USNM) in Washington DC, USA. Cecilia has been of tremendous help when I visited the Smithsonian twice. Cecilia has been an inspiration by her joyful personality, kindness and her love of insects.
Notes.
About the type locality, we received a personal communication from Eduardo Shimbori to consider ‘ Estado da Guanabara’ as a proxy for the current municipality of Rio de Janeiro. That is because this former state was fairly small and most of its area corresponds to what is now the territory of the capital of the actual Rio de Janeiro state (the Wikipedia page shows in red the area of the Guanabara state compared to the area of the Rio de Janeiro state: https://pt.wikipedia.org/wiki/Guanabara). In old maps of the Estado da Guanabara it is possible to see a river named Rio Grande (close to Pedra Branca); this is a very common name for rivers in Brazil, and there are probably hundreds of ‘ Rio Grande’ rivers in the country. As for Represa, this could be any small dam made in that river (e. g., a farmer could make a small dam to have a lake within his property and people will call it Represa). In conclusion, checking old maps and the location of Pedra Branca, it is correct to say that this location is in the municipality of Rio de Janeiro, probably in Jacarepagua, which is a large neighborhood in the west part of the city. In fact, there is a small neighborhood called Rio Grande very close to the possible collection site, which corroborates the hypothesis that this is the area referred to in the label. Unfortunately, no dam could be located in the area, even though some small lakes or ponds can be seen between Pedra Branca and the Rio Grande neighborhood (e. g., https://maps.app.goo.gl/QifF1ixJY53TwQo19).
