Necydalis barbicrus Kirby, 1818: 443 ; 1834: 68. Epimelitta barbicrus ; Monné, 2005: 460 (cat.).

Diagnosis: see under the description of F. manni .

Redescription: male ( Figs. 1A, 1B ): 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 ): 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.
