Spilogona biguttata Emden, 1951 ( Figs 1–4 )

Holotype male seen; in good condition. One male paratype from Sierre Leone was dissected and illustrated. Male terminalia. Sternite 5 with posterior membrane deep; few setae on disc and with one isolated seta on each

anterior lobe ( Fig. 1 ); cercal plate and surstylus elongated (Figs 2,3), surstylus sinuous in dorsal view ( Fig. 2 ); the

relatively elongated cercal plate and surstylus resemble those of many Holarctic species of Spilogona , a genus in which considerable diversity of form in these external genital appendages is known (e.g. Huckett 1965; Gregor et al. 2016); aedeagal complex as in Fig. 4 , hypandrium “U” shaped.
