Diagnosis

Females of Epeirotypus jane sp. nov. resemble those of E. kote sp. nov. by the vulval bifid sclerotized septum forming an inverted trapezoid posteriorly ( Figs 19D View Fig , 20D View Fig ), but E. jane can be distinguished by a relatively narrow bifid septum and a darker body coloration ( Fig. 20A–D View Fig ), whereas E. kote have the bifid septum relatively wide and the body coloration lighter (i.e., whitish-yellow) ( Fig. 19A–D View Fig ).

Etymology

The specific name is derived from ‘jane’ which means ‘different’ in the Ngäbere language, currently spoken by the Ngäbe native people of Panama, and refers to the notable differences (i.e., number of pair bases) on the cox 1 nucleotide sequence.
