Mathis, 9 ♂♂, [LMC, USNM]. Remarks. This is a poorly collected species, whose tropico-equatorial distribution ranges from the Arabian Peninsula to the remote Hawaiian archipelago. The external male terminalia exhibit slight variation, in that the anterior surstylus varies from rudimentary (in the UAE material it is perceptibly oriented inwardly and distinctly shorter and smaller than in the specimens from Sri Lanka and Taiwan ) to distinctly rod-like. Furthermore, in the specimens examined here, the outline of the posterior surstylus, in posterior view, shows a more or less distinctly enlarged mesal lobe (fig. 13).
