Panamapoda gen. nov.

Figs. 2A, 2B

Type species: Phygopoda panamensis Giesbert, 1996 , designated here by monotypy.

Etymology: the generic name is to remind us that this genus comes from Panama, Panama, and poda, that it is closely related to Pseudophygopoda . The genus is female.

Diagnosis: separation of Panamapoda from Pseudophygopoda is set down under the description of the latter; their similarities to each other, and their difference from the other genera set down below.

Panamapoda is closest to Pseudophygopoda , with which it shares the following characters (not, or less often found among the remaining genera included in this revision): in male inferior lobes of eyes contiguous or nearly so (in Paraphygopoda nearly contiguous to further apart, in Paramelitta and Phygomelitta far from contiguous); pronotum almost entirely covered with dense, tidy, recumbent, metallic coloured pubescence (in the remaining genera pronotal pubescence not recumbent, in Paramelitta may be dense and rufous in colour, in Phygomelitta rather sparse, untidy, and ashy coloured, in Paraphygopoda pronotum almost glabrous); pronotum with shining, impunctate areas limited to median and paired lateral calli (in Paraphygopoda similar, but all of surface shining, in Paramelitta and Phygomelitta impunctate areas absent or limited to median callus); metafemoral clave about 1.3 longer than peduncle (in the remaining genera metafemoral clave either much shorter, 0.6-0.9 length of peduncle; or longer, 1.8-2.8 length of peduncle); and metatarsomere I distinctly longer than length of II and III together (in the remaining genera metatarsomere I, equal to, or only slightly longer than length of II and III together, but see female P. viridimicans ).

Description of the genus (female not known): total length 10.0- 12.3 mm. Forebody (f) shorter than abdomen (a), f/a 0.84.

Head: rostrum rather short, width/length 2.56. Galea rather long. Inferior lobes of eyes almost contiguous in male, width of one lobe/interocular distance 7.5. Superior lobes of eyes lobate, laterally narrowed by about one third their mesal width; and separated by 2.75 the width of one lobe. Apex of antennae reaching apical third of urosternite II. Length of scape 0.7 mm; antennomere III 1.4 longer than scape; XI with long, narrow apical cone.

Prothorax slightly elongate (length/width 1.06); cylindrical, with weakly rounded sides, widest at middle, prothoracic quotient 2.05; callus at midline almost complete, weakly raised, impunctate, and partly widened. Prosternum only moderately declivous across middle. Prosternal process weakly arced; 14 times narrower than width of procoxal cavity.

Elytra 2.2 longer than width of humeri; apex reaching basal third of urosternite II; subfissate for about half their length; laterally weakly arced and hardly divergent apically. Each elytron strongly narrowed to apical third, the latter drawn out to form lobe with weakly rounded sides; and rounded at apical margin; translucent panels poorly contrasting with rest of elytra, and commencing well behind humeri.

Widths of mesocoxal cavity/base of process 2.8. Lengths of mesosternum/metasternum 0.7. Metathorax with subparallel sides, hind margin obliquely rounded to middle of metasternum; metasternum rather flat basally, and tumid for apical half (and slightly less prominent than mescoxae).

Abdomen narrow and almost cylindrical (with slight constriction between urosternites II and III) and widest at apex of urosternite IV/base of V; urosternite I cylindrical, and rather wide; II-V quadrate, and weakly trapezoidal. Urosternite V with apical margin weakly emarginate; surface hardly differentiated, with slightly flattened, short, V-shaped area (but lacking vestiges of soleate depression). Abdominal process weakly inclined, by about 15° to abdomen.

Legs: ratio lengths front/middle/hind leg 1.0:1.3:3.1. Front and middle legs: body length/length of legs 2.8 and 2.1 respectively. Front leg: tibia slightly shorter than femur; slender, narrow at base, widening to middle, parallel-sided to apex. Middle leg: femur moderately long, 1.42 longer than length of tibia; femoral clave rather narrow, length of femur/lateral width of femoral clave 4.15; tibia slender, and parallel-sided for apical half. Hind leg: rather elegant, body length/ length of leg in male 0.9; femur subcylindrical, apex just passing apex of abdomen; clave long, peduncle short, narrow, and flattened (length clave/peduncle about 1.36). Metatibiae slender, gradually, and only slightly widening towards middle, almost parallelsided to apex; and apical half with moderately shorthaired brush. Metatarsus distinctly narrower than apex of metatibia; tarsomere I clylindrical, II pediculate and trapezoidal, III moderately long, the lobes rounded at sides, and weakly divergent; tarsomere I 1.3 longer than II + III.

Male genitalia: were not extracted from the abdomen, but the apices of the tegmen are exposed, and appear to be most similar to those of P. viridimicans .

Surface ornamentation: on pronotum with dense patches of recumbent, brassy pubescence covering much of surface, elytra almost glabrous. Underside with pale golden pubescence as follows: on prosternum sparse, moderately short, and suberect; becoming dense and recumbent (and overlaid by much longer suberect hairs) on sides of mesosternum, on basal half of metasternum, and most of metepisternum. Abdomen rather sparsely pubescent away from sides, towards sides with long erect hairs, and dense patches of recumbent pubescence on latero-basal margins of urosternites I-IV.

Puncturation on vertex of head and pronotum dense small, alveolate and rugose; on frons and pronotal calli partly impunctate; on basal two-thirds of elytra moderately dense and scabrous across base, simpler and shallower on translucent panels. Underside puncturation partly hidden by pubescence; but with dense, small, alveolate punctures embedded in matrix of micropunctures as follows: on prosternum smooth and carinate anteriorly, densely punctate posteriorly; on meso- and metasterna (towards apex of metasternum the puncturation becoming scabrous where mixed with small tubercles). On abdomen punctures small, shallow and somewhat beveled; generally sparse to moderately sparse away from sides, towards sides rather denser.

Comment: with the transference of Phygopoda panamensis to Panamapoda , the genus Phygopoda returns to its status as a South American endemic.
