Color. Coloration and structure similar to F. ishiharai but the median stripe and lateral spots on pronotum less developed, median area on scutellum between basal dark brown colored basal triangles, fuscous.

Male genitalia. Pygofer with caudal margin of lobe ventrally produced into unpigmented membranous lobe with long hair-like setae and two rows of stout short setae along caudo-median margin. Subgenital plates longer than broad, rather triangular. Styles robust, with inner arm longer than outer, apically attenuated with subapical tooth, surface rugulose. Connective longer than broad, broadest at base, then narrowed. Aedeagus with well developed, stout, bilobed, dorsal apodeme; shaft compressed, widened distally, with subapical gonopore. Anal collar process curved, pointed, with oblique rugae.

Female genitalia. Hind margin of seventh sternite truncate, posterior margin membranous twice as broad as median length.

Measurements. Male 4.9 mm long, 1.4 mm wide across eyes. Female 5.2 mm long, 1.6 mm wide across eyes.

Material examined. TAIWAN: HOLOTYPE ♂, Formosa: M. Kato ( BMNH) . PARATYPE: 1 ♀, data as for holotype ( BMNH) .

Remarks. F. rugosa resembles F. ishiharai but differs in having a thinner anal collar process, much stouter style and caudally flared aedeagal shaft.
