Phygopoda longiscopifera sp. nov.

Fig. 1-3

Holotype. Male: 7.35 mm. Deposited at MNKM.

Description of holotype ( Fig. 1 ). Forebody 1.06 longer than abdomen. Prothorax subcylindrical, 1.05 wider than head with eyes.

Surface features. Color: body almost entirely black, abdomen suffused with chestnut. Labial palpomeres chestnut, maxilla pale chestnut to yellowish; Elytra blackish at base, the rest chestnut; but large translucent panels testaceous-olive. Antennae chestnut basally, apical half paler. Legs almost entirely dark chestnut and extreme apex of metatibiae yellowish; metatarsomere I and apex of onychium chestnut, II, III and base of onychium dingy yellow. Pubescence: abdomen sparsely pubescent mesally; metatibiae densely setose for apical 9/10, to form rather narrow, sepia and ochreous colored brushes; metatarsus clothed with cream-colored pubescence. Puncturation: dense puncturation towards sides of pronotum separated by small area of smooth chitin; on translucent panels of elytra moderately large and almost uniformly separated by slightly more than their diameter; on abdomen, a mixture of different sized punctures (but none very large), almost uniformly sparse, shallow and beveled.

Structure. Head: rostrum short, width/length 3.25. Clypeus narrow, on higher plane than labrum and separated from it by raised border; but almost coplanar with frons. Frons short and hardly convex; frontal suture not deep, but narrow and well-defined, not impinging on frons; but posteriorly passing between antennal tubercles and continuing as raised line to apex of prothorax. Inferior lobes of eyes 1.26 longer than wide; contiguous (width of one lobe/interocular distance 9.50). Superior lobes of eyes narrow (ca. 0.15 mm wide medially, narrowed to ca. 0.10 mm laterally); with about 10 rows of ommatidia medially, 7 rows laterally; and separated by 2.33 times their own width. Antennal tubercles separated by 2.25 width of scape. Antennae: apex reaching middle of urosternite II and passing apex of elytra at middle of antennomere VIII. Scape subpyriform; Antennomeres IX-X hardly serrate, subcylindrical. Lengths (mm) antennal segments as follows: scape 0.5, pedicel 0.20, III 0.60, IV 0.40, V-VII 0.55, VIII 0.45, IX 0.40, X 0.35, XI 0.40.

Prothorax: length 1.25 mm, 1.18 longer than wide; sides straight and parallel for apical half, widest well behind middle (prothoracic quotient 1.47). Prosternum declivous across apical third, moderately sloping to base of prosternal process. Prosternal process arced; base of process almost laminate (ca. 0.1 mm), about 3.5 times narrower than procoxal cavities; apex of process a moderately large, flat, transverse triangle with all sides arced inwards (but details partially hidden).

Mesothorax: elytra 1.95 mm long, 1.70 longer than wide; humeri not wide enough to hide sides of meso- and metasterna; towards apex surface with slight transverse declivity. Mesosternum: width of mesocoxal cavity 2.33 wider than base of mesosternal process. Length of mesosternum/length of metasternum 0.71.

Metathorax: width 2.00 mm, body length/width metathorax 3.68; strongly rounded at sides to middle of metasternal apex. Metasternum tumid at center, about level with mesocoxae; longitudinal suture narrow, not deep, reaching basal half of metasternum. Abdomen: relatively long; convex; moderately narrow; weakly constricted between segments; urosternites I-IV widest (0.90 mm) at middle of III; narrowest (0.70 mm) at apex of IV. Urosternite I elongate (1.10 mm), sides straight; II (0.75 mm) sides slightly rounded; III (0.75 mm) sides rounded; IV (0.6 mm) sides straight. Urosternite V (0.5 mm) trapezoidal, transverse; sides sharply pointed (but viewed laterally with broad, rounded wings); surface slightly flattened for apical half. Abdominal process a short isosceles triangle coplanar with abdomen. Apical tergite convex.

Legs: ratio length front/middle/hind leg 1.0:1.2:4.8; and body length/length of leg 3.6, 3.0, 0.8 respectively. Front and middle legs moderately robust, the former rather long, the latter rather short; their claves widest at middle (when viewed from above). Front leg: tibia widening to middle, parallel-sided to apex; apico-lateral margin not toothed. Middle leg: femur 1.58 longer than tibia; length of femur/lateral width of clave 3.33. Hind leg: length 12.35 mm; femoral clave short and moderately abrupt, lengths clave/peduncle 0.42; tibiae and femora equal in length; tibia bisinuate (when viewed from above), straight (when viewed from the side); tarsus short, about one third length of tibia, and much narrower than apex of latter; metatarsomere I narrow at base, moderately widened to apex, 1.25 longer than lengths of II+III.

Male variation. Of the 23 male paratypes three have pale chestnut abdomen, legs and antennae; and in many the hind legs are paler than holotype; elytral apices tan colored in three specimens, pale chestnut in others. Rostrum may be more transverse, and sides less parallel in small specimens. Antennal variation: VI and X slightly more serrate; VIII and IX distinctly serrate; XI may vary in length and shape; apical cone may be less acuminate. In many sides of prothorax regularly rounded from apex to base; sides of pronotum may lack smooth areas. Elytra: puncturation varies from smaller to larger, sparser to denser; in three specimens, elytra noticeably narrower towards apex; in others apical margin less blunt, with sutural margin the longest. Small differences in proportions of abdomen are common; and one aberrant has a fusiform abdomen.

Description of female ( Fig. 2 ). Female allotype differs from male holotype as follows: total length 8.85 mm. Slightly more robust than male. Lengths forebody/abdomen 0.88.

Surface features. Color: elytral apices tan colored; abdomen and legs pale chestnut; base of metafemoral peduncle yellowish; metatibial brush black; metatarsus entirely bright yellow. Surface ornamentation: similar to holotype on dorsad; generally less pubescent and less densely punctured on underside (especially metathorax and abdomen).

Structure. Head: narrower (widths head with eyes/prothorax 1.21). Inferior lobes of eyes considerably shorter and narrower (length 0.45 mm, width 0.33 mm); less convex (lying slightly below level of interocular); well separated (width interocular 0.30 mm, widths lobe/interocular 1.08). Interocular flat, densely punctured; frontal suture not projecting behind eyes. Antennae reaching base of urosternite III; antennomere III 1.20 longer than scape; VII and X not serrate, VIII-IX weakly serrate, otherwise little different from holotype.

Prothorax: less elongate, 1.09 longer than wide; sides straight, but diverging towards basal half; prothoracic quotient 1.67 (i.e. wider nearer middle); and, unique to this female specimen, lacking smooth areas towards sides of pronotum. Prosternum flatter; base of process not arced, wider than holotype (widths procoxal cavity/base of process 2.80).

Meso- and metathorax: elytra slightly shorter (but also reach base of uorosternite 1), broader, length/ width 1.58; less dehiscent. Meso- and metathorax very similar to those of holotype, except: mesosternal declivity less abrupt; metasternum less tumid at center (lying slightly below level of metacoxae).

Abdomen: fusiform, wider than holotype; length urosternites 1-V: 1.25, 0.80, 0.75, 0.60, 0.8); V subconical and much longer; abdominal process exceptionally broad, giving urosternite I a conical appearance. Last visible tergite conical, elongate, weakly convex, rounded at apex.

Legs: slightly more robust and shorter than in male, ratio of length from front to hind leg 1.0:1.2:4.4; total body length/length of leg 3.6, 3.0, 0.8 respectively. Middle leg: femur 1.40 longer than tibia; length of femur/lateral width of clave 4.00; clave 2.10 longer than peduncle. Hind leg: slightly shorter (10.90 mm); clave more abrupt and shorter (but apex also passes abdomen at base of clave); peduncle longer (lengths clave/peduncle 0.30); femur hardly longer than tibia (lengths femur/tibia 1.02); tibia weakly arced (when viewed from the side); tarsus 3.92 shorter than tibia; metatarsomere I wider, 1.30 longer than lengths of II+III; II distinctly trapezoidal.

Color variation in females. General color: one as male holotype; four more like allotype, but with pale chestnut head and prothorax ( Fig. 3 ); two intermediate; and one as allotype. Of the eight paratypes, none with base of femoral peduncle yellow; and five have sepia colored brushes on metatibiae.

Diagnosis. The specific epithet of Phygopoda longiscopifera provides its most obvious diagnostic, with its setal brush being nearly as long as the metatibia, while never longer than two-thirds of tibia in other species of the genus.
