Other records — Epixanthus frontalis - Lenz, 1910 : 552, Grande Comore; également Madagascar et île Europa. - Guinot, 1958c : 276, Mayotte, 1 F 8 x 5 mm MNHN. - Guinot, 1967: 270, list with Mayotte. - Crosnier, 1984: 307, pl. XLV F, fig. 222-223, Mayotte, Madagascar, MNHN.
Remarks — Several specimens erroneously determined in the field (st. 10, 26) as Pseudozius caystrus, corrected into E. frontalis after careful re-examination in MNHN, July 2011. Although the two species have superficial resemblances they can be easily differentiated by the aspect of male G2 : short without distal flagellum, in P. caystrus, versus elongated with a long distal flagellum, either cross-shaped or coiled, in E. frontalis.
