This species may be distinguished from other members of the genus by the moderately elongated antennomere XI in the male, the size of the eye in frontal view (separated by between 1.5 and 2.0 times width of one eye), the elytral interval microsetae in two rows, the acuminately pointed penis that is parallel-sided in apical half, and by the fused parameres of the tegmen hexagonal. Holotype . Male , genitalia dissected and mounted in DMHF on card with specimen, with label data “ MADAGASCAR : \ Antsiranana \ 6.5km ssw. \ Befingot[r]a rsrv. \ 14°45′S 47[49]° 30′E \ 17–31.X.1994 875m \ BLFisher #1067 MT // HOLOTYPE \ Nesiotus \ fisheri Gimmel \ des.

Ventral coloration similar. Appendages testaceous. Head : Eyes separated by about 1.5–2.0 times width of a single eye in frontal view ( Fig. 29 ).

Prosternal process with 1 pair of apical setae, setae located at posterolateral corners. Elytral interval microsetae in 2 irregular rows. Metaventral lines extending posteriorly about one-half distance from mesocoxa to metacoxa. Genitalia : Penis ( Fig. 7 ) with acutely pointed apex; parallel-sided in apical half; basal strut long and narrow; internal sac sclerites as illustrated. Tegmen ( Fig. 14 ) with fused parameres hexagonal, with 1 pair of setae lateroapically; basal piece widest in apical half; with 3 acuminate basal struts, middle strut extending anteriorly well beyond level of basal ring, lateral struts much shorter and converging anteriorly.
