Phygopoda boliviensis sp. nov.

Fig. 4

Holotype. Male: 7.60 mm. Deposited at MNKM. Female not known.

Description of holotype ( Fig. 4 ). Forebody 1.25 longer than abdomen. Prothorax subcylindrical, 1.14 wider than head with eyes.

Surface features. Color: body black, prothorax suffused with chestnut towards sides of pronotum, part of prosternum and abdomen. Labial and maxillary palpomeres chestnut. Elytra dark chestnut, humeri paler, large translucent panels testaceous olive. Antennae black basally, rest brownish. Legs generally dark chestnut; basal third of metafemoral peduncles and extreme apex of metatibiae yellow; metatarsi ochreous-yellow (apex of onychia chestnut). Pubescence: abdomen sparsely pubescent mesally; denser on underside of pro- and mesofemora; on metatibiae densely setose for apical two-thirds, to form moderately wide, black and sepia-colored brushes; metatarsus clothed with creamy-yellow pubescence. Puncturation: punctures on translucent panels of elytra moderately large and almost uniformly separated by slightly more than their diameter; on center of metasternum becoming rugose; on abdomen almost uniformly small, sparse, shallow and beveled.

Structure. Head: rostrum wide, moderately long (width/length 2.80), sides parallel. Clypeus narrow, declivous across center, on lower plane than labrum and separated from it by raised border; but almost coplanar with frons. Frons moderately short and slightly depressed; frontal suture almost evanescent, just traceable to hind margin of eyes. Inferior lobes 1.30 longer than wide; width of one lobe/interocular distance 10.00. Superior lobes of eyes narrow (ca. 0.15 mm wide medially, narrowed to ca. 0.10 mm laterally); with about 9 rows of ommatidia medially, 7 rows laterally; and separated by about 2.67 times their own width. Antennal tubercles separated by 3.33 width of scape.

Antennae: apex reaching apex of urosternite II and passing apex of elytra towards base of antennomere VII; IX-X subcylindrical, hardly serrate; XI sub-ovate. Lengths (mm) antennal segments as follows: scape 0.45, pedicel 0.20, III 0.65, IV 0.45, V 0.60, VI-VII 0.55, VIII 0.45, IX 0.40, X 0.35, XI 0.40.

Prothorax: elongate, 1.40 mm, 1.17 longer than wide; sides slightly sinuate for apical half, widest behind middle, prothoracic quotient 1.65. Prosternum declivous across apical third, sloping to base of prosternal process. Prosternal process arced; base of process sub-laminate (ca. 0.10 mm), about 3.5 times narrower than procoxal cavities; apex of process a moderately large, flat, equilateral triangle with apical margin arced inwards (but details partially hidden).

Mesothorax: Elytra: length 1.90 mm, 1.52 longer than wide (1.25 mm); humeri not wide enough to hide sides of meso- and metasterna; towards apex surface with slight transverse declivity. Mesosternum: width of mesocoxal cavity 2.67 wider than base of mesosternal process. Length of mesosternum/ length of metasternum 0.60.

Metathorax: width 1.4 mm, body length/width metathorax 5.43; strongly rounded at sides to middle of metasternal apex. Metasternum convex, hardly tumid at center; longitudinal suture narrow, not deep, reaching base of metasternal process.

Abdomen: relatively short; convex; urosternites I-IV widest (0.83 mm) at middle of III, narrowest (0.75 mm) at apex of IV. Urosternite I elongate (0.8 mm); II (0.60 mm) sides slightly rounded; III (0.60 mm) sides rounded; IV (0.60 mm) sides straight. Urosternite V (0.45 mm) trapezoidal, transverse, convex; sides sharply pointed, and the same when viewed laterally. Apical tergite flattish.

Legs: ratio length front/middle/hind leg 1.0:1.2:4.1; and body length/length of leg 2.7, 2.3, 0.6 respectively. Front and middle legs moderately robust, rather long; profemoral clave widest at middle, mesofemoral clave widest towards apex (when viewed from above). Front leg: tibia gradually widening to apex; apico-lateral margin toothed. Middle leg: femur 1.73 longer than tibia; length of femur/lateral width of clave 3.67. Hind leg: length 11.80 mm; clave comparatively long and abrupt; lengths clave/ peduncle 0.49; tibiae and femora equal in length; tibia straight (when viewed from above), bisinuate (when viewed from the side); tarsus short (1.45 mm), less than one third length of tibia, and narrower than apex of latter; metatarsomere I pediculate at base, parallel-sided to apex, 1.30 longer than lengths of II+III.

Diagnosis. Metatibial brushes wide, covering apical two-thirds of tibia (in P. longiscopifera brushes narrower and longer; in P. chaquensis metatibia without true brush).

Species sample data.

Measurements (mm): 1 male: total length 7.6; length of pronotum 1.4; width of pronotum 1.2; length of elytra 1.90; width at humeri 1.25.

Type material: Holotype male, BOLIVIA, Santa Cru z, Hotel Flora and Fauna, 5 km SSE of Buena

Vista, 17°29’96'’S/63°39’13'’W, 440 m, on/flying to flowers of “Sama blanca”, 12.XI.2005 ( MNKM).

Etymology. The specific epithet, “boliviensis”, simply means “from Bolivia ” in Latin.
