Diagnosis.

This species is similar to F. latefasciata Miyatake but it can be distinguished from the latter as follows: body uniformly black with purple shine, without spots (Figure 2 a–c); penis guide of tegmen in ventral view narrow with a nipple-shaped apex (Figure 2p, q); apex of the penis truncate, membranous (Figure 2o). In F. latefasciata , pronotum reddish yellow, elytra blackish and shiny, with a broad transverse reddish yellow band in the middle (Figure 1 a–c); penis guide of tegmen in ventral view broad and flat, with rounded apex (Figure 1r); apex of the penis pointed (Figure 1o, p).

TL: 1.99-2.63 mm, TW: 1.84-2.55 mm, TH: 1.28-1.8 mm, TL/TW: 1.03-1.08; PL/PW: 0.40-0.49; EL/EW: 0.93; HW/TW: 0.34-0.39; PW/TW: 0.59-0.60.

Color: Head, pronotum, scutellum, elytra purplish shiny black, without spots (Figure 2 a–c). Underside blackish brown, except yellowish claws.

Pronotum glabrous, with uniformly distributed punctures (Figure 2 a–c). Scutellum of isosceles triangle shape (Figure 2a, c). Elytral surface uniformly punctate (Figure 2 a–c). Prosternum, mesoventrite, and metaventrite with scattered golden pubescence and inconspicuous punctures (Figure 2k, l). Elytral epipleuron with uniform golden pubescence. Legs with dense golden pubescence (Figure 2j, l). Abdomen with sparse golden pubescence and uniformly distributed punctures (Figure 2m).

Male genitalia. Tegemen stout and symmetrical, tegminal strut stout and straight; penis guide in lateral view almost straight and gradually narrowing along apical third to pointed apex, with membranous prominence at basal half; in ventral view narrowest at base and gradually broadening to apex, then strongly narrowed to form a nipple-shaped apex; parameres with dense long setae apically, longer than penis guide; phallobase membranous (Figure 2p, q). Penis uniformly tubular, curved, basal capsule membranous, without distinct arms; apex of penis subtruncate with membranous appendage (Figure 2n, o).
