Thyanta humilis viridescens Kuhlgatz , nomen dubium

Thyanta humilis var. viridescens Kuhlgatz, 1903:256-257 ; Kirkaldy, 1909:94.

Kuhlgatz (1903) described viridescens as a variety of T. humilis . Although his description is fairly detailed for its time, this taxon cannot be identified with any certainty. The type specimens may have been destroyed during World War I or II. Kuhlgatz listed the distribution of viridescens as being from Panama to Guayaquil, Ecuador. The present study has placed T. humilis as a junior synonym of T. patruelis , which occurs from central Brazil and southern Peru to Argentina. So, it is unlikely that viridescens is a subspecies of humilis ( =patruelis ). Thyanta humilis viridescens should be considered a nomen dubium.
