Diagnosis: see under the description of F. manni .

Redescription: male ( Figs. 1A, 1B View FIGURES 1‑2 ): rather robust; length of forebody 0.8 times length of abdomen ( 5.75 mm); prothorax 1.19 wider than width of head across eyes ( 1.55 mm).

Colour: body generally black, or almost so; underside of head, mandibles, labrum and clypeus may be dark chestnut; antennae dark chestnut, or blacker, and all antennomeres weakly annulated with ochraceousyellow; extreme elytral apex nearly always ochraceous yellow or rufous-chestnut; metafemora with ochraceous-yellow peduncles, claves black or dark chestnut dorsally, rufous-chestnut ventrally; metatibia with basal quarter yellowish; metatarsi blackish or dark rufescent.

Structure: head robust; rostrum 3.29 wider than long ( 0.35 mm). One inferior lobe of eye 3.50 wider than interocular distance ( 0.20 mm). Distance between superior lobes of eyes twice width of one lobe ( 0.25 mm). Distance between antennal tubercles 2.67 width of scape ( 0.30 mm). Lengths of antennal segments: scape 0.70 mm; pedicel 0.2 mm; III-VI 0.60 mm; VII and VIII 0.55 mm; IX 0.50 mm; X 0.45 mm; XI 0.50 mm.

Prothorax 1.08 longer than wide ( 1.85 mm); prothoracic quotient 3.33; apical margin as wide as basal margin ( 1.65 mm). Procoxal cavity 8.67 wider than base of prosternal process (about 0.08 mm). Mesocoxal cavity 1.44 wider than base of mesosternal process ( 0.45 mm). Elytra 1.36 longer than width across humeri ( 2.20 mm); just passing metacoxae. Length of mesosternum 1.00 mm; length of metasternum 1.25 mm. Abdominal segments incrementally shorter towards apex; length urosternite I 1.60 mm; II 1.25 mm; III 1.15 mm, IV 0.90 mm; V 0.60 mm. Ratio front/middle/hind leg 1.0:1.1:2.4. Profemur 1.17 longer than protibia ( 1.50 mm); mesofemur 1.40 longer than length of mesotibia ( 1.50 mm); mesofemur 2.47 longer than width of clave ( 0.85 mm). Body 1.2 longer than hind leg (about 10.4 mm); metafemoral clave 2.40 longer than peduncle ( 1.25 mm); apex of metafemora reaching middle of usosternite IV. Metatibia 0.92 times length of metafemur ( 4.25 mm); metatibia 1.73 longer than metatarsus ( 2.25 mm); brush occupying apical three-quarters of tibia. Metatarsomere I 1.06 longer than length of II + III.

Description of female ( Fig. 1C View FIGURES 1‑2 ): sexual dichromatism diminished, but in female elytra with all of apical third ochraceous-yellow.

Structural dimorphism only moderately strong; differing significantly from male by the following characters: forebody 0.96 times length of abdomen ( 5.75 mm); prothorax 1.42 wider than width of head across eyes ( 1.55 mm); rostrum 2.40 wider than long ( 0.50 mm). One inferior lobe of eye 0.91 times interocular distance ( 0.55 mm). Distance between su- perior lobes 2.40 width of one lobe. Antennae reach middle of metacoxae; antennomere III 0.77 times length of scape ( 0.65 mm). Length of prothorax 0.93 times its width ( 2.20 mm); prothoracic quotient 3.15. Procoxal cavity 6.50 wider than base of prosternal process ( 0.10 mm). Mesocoxal cavity 1.08 wider than base of mesosternal process ( 0.60 mm). Elytra reaching base of urosternite I. Ratio front/middle/hind leg 1.0:1.2:2.6. Mesofemur 2.67 longer than width of clave ( 0.75 mm). Metafemoral clave 2.61 longer than peduncle ( 1.15 mm). Metatibia 1.93 longer than metatarsus ( 2.05 mm). Metatarsomere I 1.13 longer than length of II + III.
