Amended diagnosis. Male terminalia. Pygofer in lateral view broadest subdorsally, narrowed ventrad, anterior margin concave, posterior margin bearing large rounded lobe at caudodorsal angle and an elongated acuminate process near midlength, ventral margin nearly linear, medioventral process lacking. Gonostyli in lateral view broad, weakly spatulate (dorsal margin straight—excepting capitulum—ventral margin weakly convex except broadly rounded along ventrocaudal margin, apex rather truncate; capitulum relatively short, apex diagonally truncate crowned with a flanged margin. Aedeagus nearly symmetrical, weakly upcurved, with a pair of subapical ventral processes and a pair of subapical lateral processes; ventral processes closely approximated, much shorter than subapical lateral processes, acuminately pointed (about ¼ length of aedeagus); lateral processes nearly 2/3 length of aedeagus, symmetrical, with a short upward projected process proximad, and apical third forked into a pair of elongate forks ( Fennah 1955: fig. 2r illustrates the left side as not forked). Anal segment in lateral view elongate, downcurved at epiproct, distally greatly enlarged with apex concave; in dorsal view antal tube elongate, parallel-sided, bifid past paraproct; paraproct thin and elongated.

Remarks. Jamaha elevans was previously reported, and illustrated, from Jamaica by Fennah (1955). The species was subsequently made the type species of the then-new genus Jamaha by Gnezdilov and O’Brien (2008). In Fennah’s (1955) illustrations (fig. 20s), the lateral processes of the aedeagus are not symmetrical, but the right side is forked and the left is not, but the Kingston specimens that we examined otherwise appear the same as those illustrated by Fennah (1955).
