Diagnosis. Chirotica pothina can be distinguished from all other Neotropical Chirotica species by the combination of the following characters: (1) antenna with a reddish-brown median band and blackened apex (Fig 29A); (2) pronotal collar black (Fig 29A); (3) region between posterior ocelli with weak rugae and punctuation (Fig 29B); (4) tergites 2 and 3 with medial punctuation and lateral rugae (Fig 29E).

Distribution. Brazil (São Paulo **), Grenada (Ashmead 1895; Townes 1983; Yu et al. 2016), St. Vincent (Ashmead 1900b; Yu et al. 2016), Trinidad & Tobago (Townes 1983; Yu et al. 2016), Venezuela (Marshall 1982; Townes 1983; Yu et al. 2016) (Fig. 29G).

Host. Pupae of Psychidae ( Lepidoptera) on Chromolaena odorata (L.) R. King & H. Rob. ( Asterales: Asteraceae) (Townes 1983).

Discussion. Chirotica pothina is morphologically similar to C. nigra sp. nov. having mesopleuron with dense punctuation and long setae; tergite 1 with sparse punctuation and without lateromedian carinae; and epicnemium with dense punctuation and long setae. However, C. pothina differs from C. nigra sp. nov. in the following characters: mesoscutum granulated, with punctuation and rugae on posterocentral part (Fig. 29D) (versus C. nigra sp. nov. which has mesoscutum weak rugose-punctuate and with posterolateral matted areas (Fig. 26D)); area below the juxtacoxal carina rugose-punctuate, tergites 2 and 3 with central punctuations and lateral rugae (versus C. nigra sp. nov. which has area below the juxtacoxal carina with fine punctuation and tergites 2 and 3 with sparse fine punctuation); area of stemmaticum with weak rugae and punctuation between posterior ocelli (Fig. 29B) (versus C. nigra sp. nov. which has area of stemmaticum with median longitudinal sulcus between posterior ocelli and not extending to vertex (Fig. 26B)).
