Diagnosis. This species is either closely related to or less likely conspecific with J. serpentina . They are nearly identical, except that in Jethsura sp. X the ventral 0.6 of the mesopleuron is longitudinally rugulose. The yellow markings on the head may be less extensive than in J. serpentina as well.

Comments. I have chosen to leave Jethsura sp. X undescribed, since an adequate description and images could not be provided. The lack of specimens also leaves some uncertainty as to whether Jethsura sp. X is conspecific or not with J. serpentina . The singleton representing this species was originally grouped with J. serpentina and was used in a whole-body DNA extraction. Upon further examination, the specimen was found to likely represent a new species. Unfortunately, the extraction process left it bereft of color and in a generally poor condition. Therefore, sufficient material was unavailable to provide a high-quality description and images.

Similar to J. serpentina , Jethsura sp. X was collected at high elevation above 3000 m. The collection data for the singleton of Jethsura sp. X are “ Colombia, Cundinamarca, PNN Chingaza, Valle de Fraylejon, 4 31’N, 73 45’W, 3170m, 28.ii.–2.iii.2001, Elias & Amuifo, M. 1488”.
