Distribution. Brazil (Bahia, Roraima) (Fig. 23G).
Host. Unknown.
Etymology. Derived from the Tupi word “ juquiá ”, which is one of the variations of the original word of the name of the city where the holotype was collected (“ jequié ” = “ jequiá ”, “ jiquiá ” and “ juquiá ”). Noun in opposition.
Holotype condition. Complete specimen, glued to entomological pin on the lateral part of the mesosoma.
Discussion. Chirotica juquia sp. nov. is similar to C. parallela having tergite 1 with sparse small punctuation and without lateromedian carinae; metapleuron and area below juxtacoxal carina of both species with rugae; mesoscutum with rugae and narrow frosted and granulated band centrally (Figs 23D and 28D). However, C. juquia sp. nov. differs from C. parallela in the following characters: ovipositor with a smooth and sinuous upper valve, sinuous lower valve with large teeth proximal at apex (Fig. 23F) (versus C. parallela which has ovipositor with upper valve and lower valve with small teeth at apex (Fig. 28F)); central part of the mesoscutum has postcentral rugae (Fig. 23D) (versus C. parallela which has central part of the mesoscutum with postcentral striae (Fig. 28D)); and the epicnemium with punctuation (versus C. parallela which has epicnemium rugose-punctuate).
