Phygopoda manni Fisher, 1930: 15 .

Epimelitta manni ; Monné, 2005: 461 (cat.).

Diagnosis: this species is readily separated from Fissapoda barbicrus by the following: in F. manni hind legs appear to be longer (as the abdomen is short), with apex of metafemora passing apex of elytra in male, in female reaching middle of urosternite V (in both sexes of F. barbicrus apex of metafemora do not pass apex of elytra, and only reach middle of urosternite IV); in F. manni apex of elytra rather narrow, and normally black, only in specimens with pale rufous metafemora apex ochraceous-orange (in F. barbicrus apex of elytra rather broad, and always ochraceous-orange); in males of F. manni prothorax subcylindrical and pro- notal calli weakly developed (in F. barbicrus prothorax cylindrical, more so in male, and pronotal calli prominent, disrupting profile of sides); in F. manni male abdomen more fusiform and short (in F. barbicrus more cylindrical and longer); in female F. manni apical tergite without dense recumbent pubescence (in female F. barbicrus clothed with dense, creamy-yellow, recumbent pubescence); in F. manni metatibial brush shorter, occupying apical two-thirds of tibia (in F. barbicrus brush occupying apical three-quarters of tibia); in F. manni metatarsomere I shorter than II + III together, I/II + III 0.9 (in F. barbicrus I/II + III 1.1).

In the field identification only requires a cursory glance at the underside; in both sexes of F. manni the abdomen is densely clothed with recumbent, long, white pubescence (in both sexes of F. barbicrus the abdomen is only sparsely, and not eye-catchingly pubescent).

Redescription: male ( Fig. 2A ): moderately robust; length of forebody 1.06 length of abdomen (4.70 mm); prothorax 1.29 wider than width of head across eyes (1.55 mm).

Colour: body generally black, base of mandibles, labrum and clypeus usually pale chestnut; antennomeres uniform pale chestnut (without paler annulations); apical third of elytra nearly always black (but see pale forms, and in some males from Brazil apices of elytra rufescent and abdomen partly, or entirely pale chestnut); metafemora black (mostly pale chestnut in pale forms), with base of peduncles pale yellow; metatibia with basal sixth yellowish; metatarsi yellow.

Structure: head rather narrow and female-like; rostrum 3.83 wider than long (0.30 mm); one inferior lobe of eye 4.67 wider than interocular distance (0.15 mm). Distance between superior lobes of eyes twice width of one lobe (0.25 mm). Distance between antennal tubercles 3.20 width of scape (0.25 mm). Lengths of antennal segments: scape 0.70 mm; pedicel 0.20 mm; III 0.60 mm; IV 0.50 mm; V and VI 0.55 mm; VII and VIII 0.50 mm; IX 0.45 mm; X 0.40 mm; XI 0.50 mm. Prothorax 1.05 longer than wide (2.00 mm); prothoracic quotient 2.21; apical margin 0.94 times width of basal margin (1.65 mm). Procoxal cavity 8.67 wider than base of prosternal process (about 0.08 mm). Mesocoxal cavity 1.09 wid- er than base of mesosternal process (0.55 mm). Elytra 1.35 longer than width across humeri (2.15 mm); just passing metacoxae. Length of mesosternum 1.05 mm; length of metasternum 1.25 mm. Abdominal segments I-IV incrementally shorter, IV and V equal in length; length urosternite I 1.45 mm; II 0.85 mm; III 0.80 mm, IV and V 0.60 mm. Ratio front/middle/ hind leg 1.0:1.1:2.8. Profemur 1.11 longer than protibia (1.40 mm); mesofemur 1.48 longer than length of mesotibia (1.35 mm); mesofemur 2.50 longer than width of clave (0.80 mm). Body and hind leg equal in length (about 11.4 mm); metafemoral clave 5.07 longer than peduncle (0.75 mm); apex of metafemora just passing apex of abdomen; metatibia 1.02 longer than metafemur (4.55 mm); metatibia 2.11 longer than metatarsus (2.20 mm); metatibial brush occupying apical two-thirds. Metatarsomere I 0.89 times length of II + III.

Redescription of female ( Figs. 2B, 2C ): females are rather scarce in collections, but those examined hardly differing from males in colour (except apparent lack of rufous forms among this sex).

Structural dimorphism only moderately strong; differing significantly from male by the following characters: forebody and abdomen equal in length (5.00 mm); prothorax 1.42 wider than width of head across eyes (1.55 mm); rostrum 3.00 wider than long (0.40 mm); one inferior lobe of eye 0.91 times interocular distance (0.55 mm); distance between superior lobes 2.80 width of one lobe. Antennae reach middle of metacoxae; antennomere III 0.77 times length of scape (0.65 mm). Length of prothorax 0.97 times its width (2.00 mm); prothoracic quotient 2.35. Procoxal cavity 6.00 wider than base of prosternal process (0.10 mm). Width of mesocoxal and base of mesosternal process equal (0.65 mm). Elytra reaching base of urosternite I. Ratio front/middle/hind leg 1.0:1.1:2.9. Mesofemur 2.86 longer than width of clave (0.70 mm). Metafemoral clave 3.17 longer than peduncle (1.15 mm). Metatibia 2.24 longer than metatarsus (2.10 mm). Metatarsomere I 0.94 times length of II + III.
