Type species: Stenopterus albitarsis Klug, 1825 , here designated.
Etymology: the generic name is to remind us that this genus comes from Panama, Panama, and poda, that it is related to Pseudopygopoda. The genus is female.
Diagnosis: metafemora distinctly pedunculate clavate (in all other genera metafemora subcylindrical); meta- tarsi about as wide as apex of metatibia (in all other genera metatarsi narrower than apex of metatibia); pronotal surface shining and almost glabrous (in all other genera the surface dull and pubescent).
Description of the genus: total length 9.0-16.0 mm. Forebody (f) shorter than abdomen (a), f/a 0.83-0.91 (in most species), to slightly longer than abdomen f/a 1.09 (in P. nappae ).
Head: rostrum width/length 2.27-2.63 (shortest in P. albitarsis , longest in P. nappae ). Galea long, or rather short (in P. albitarsis ). Inferior lobes of eyes subcontiguous to contiguous in males, width of one lobe/interocular distance 5.83-7.75 (widest apart in P. viridimicans , nearest together in P. nappae ); well separated in females, width of one lobe/interocular distance 0.83-1.00. Superior lobes of eyes usually lobate (but fusiform in male P. nappae ); laterally usually narrowed by about one third their mesal width (but not narrowed in male P. viridimicans , and laterally narrowed by about half their mesal width in P. albitarsis ); and separated by about three times the width of one lobe. Apex of antennae in males reaching from base of urosternite II (in P. panamensis ) to apex of urosternite III (in P. longipennis ); in females nearly reaching, or just passing, middle of II. Length of scape 1.4-1.7 mm; antennomere III 1.3-1.6 longer than scape (longer in males); XI as long as, or slightly longer than X, with narrow apical cone.
Prothorax quadrate (in females), hardly longer in males, length/width 1.04-1.11 (most elongate in P. nappae ); subcylindrical, with sides slightly converging towards apex, and somewhat widened near middle, prothoracic quotient in male 2.05-2.16, in females 1.94-2.05; callus at midline incomplete, flattish, impunctate, and partly widened. Prosternum moderately declivous across middle, and inclined to prosternal process (in most species), flatter and abruptly inclined to process (in P. viridimicans ). Prosternal process weakly arced in male, flat in female; 13-15 times narrower than width of procoxal cavity.
Elytra 2.0-2.3 longer than width of humeri (shortest in male P. albitarsis , longest in P. viridimicans ); apex reaching apex of urosternite I (in females, and male P. nappae ), from base to apex of II (in most males); subfissate for about half their length; laterally strongly arced and divergent apically (in most males), less so (in females, and in male of P. nappae ). Apical third of each elytron lobed, the latter with moderately rounded sides, and rounded or obliquely truncate apical margin; each elytron with well-defined, broad translucent panel commencing near basal margin (in P. albitarsis and P. viridimicans ), or narrow and commencing just behind humeri (in P. nappae ).
Widths of mesocoxal cavity/base of process 2.14-3.00 in male, 2.00 in female. Lengths of mesosternum 0.63-0.71 length of metasternum. Metathorax with subparallel sides, oblique, or almost truncate, to middle of metasternum (in P. viridimicans ), or sides rounded from base to middle of metasternum (in P. albitarsis and P. nappae ); metasternum uniformly tumid (in P. albitarsis and P. nappae ), or rather flat basally, and tumid for apical half (in P. viridimicans ).
Abdomen in male almost cylindrical, slightly wider for apical half, widest at middle of urosternites III. Urosternite I weakly conical, or cylindrical (in P. viridimicans ); II-IV rectangular and transverse, or weakly trapezoidal, and like III and IV quadrate (in P. viridimicans ). Urosternite V in male trapezoidal and strongly transverse, or weakly trapezoidal and quadrate (in P. viridimicans ); surface weakly differentiated, slightly flattened from midline towards sides (but lacking vestiges of soleate depression); with apical margin strongly emarginate, and with acute apicolateral angles (when viewed from the side). Abdomen in females fusiform; flattened, and widest near middle of III; urosternite I conical; II-IV transverse (in most species), with III quadrate (in P. albitarsis ). Urosternite V narrow (in P. nappae ), or very narrow (in P. albitarsis and P. viridimicans ), conical, and slightly flared at apex. Abdominal process usually weakly inclined to abdomen in males (and see P. nappae ), or narrowly triangular, and distinctly inclined to abdomen (in P. viridimicans ).
Legs: ratio lengths front/middle/hind leg 1.0:1.3-1.5:3.2-3.7. Front and middle legs: body length/length of legs 2.6-3.3 and 2.0-2.3 respectively. Front leg: tibia slightly shorter than femur (in both sexes); slender, narrow at base, and widening to apex (somewhat abruptly in P. albitarsis ). Middle leg: femur moderately long, especially in males, 1.33-1.47 longer than length of tibia; femoral clave moderately broad in males (less so in females), length of femur/lateral width of femoral clave 3.8-5.0; tibia slender, and parallel-sided for apical two-thirds, or gradually widened to apex (in P. nappae ). Hind leg: slender, body length/ length of leg 0.8-0.9 (in both sexes); femur abruptly pedunculate-clavate, with apex just passing apex of abdomen, or, with its short abdomen, apex passing abdomen near base of femoral clave (in P. nappae ); femoral clave very short, peduncle narrow, flattened, and long to very long, lengths of femoral clave/peduncle about 0.62-0.86 (in P. albitarsis and P. viridimicans ), or 0.56 (in P. nappae ). Metatibiae slightly longer than metafemora, or slightly shorter than metafemora (in P. albitarsis ); somewhat robust, gradually, and only slightly, widening towards middle, almost parallelsided to apex; and apical half with long-haired brush. Metatarsus about as broad as apex of metatibia; metatarsomere I subclylindrical, II trapezoidal and weakly pedunculate, III moderately long, the lobes slightly rounded at sides, and weakly divergent; tarsomere I longer than II + III (in P. albitarsis and P. longipennis ), equal in length to II + III (in P. nappae ), and 1.4-1.5 longer than II + III (in female P. viridimicans ).
Genitalia ( Figs. 11, 13 View FIGURES 8‑14 ): the tegmen of the two species examined rather different: that of P. albitarsis closer to that of P. subvestita (see below this species for details); and that of P. viridimicans , with lateral lobes more rounded mesally, but not abruptly excavate before apical lobes: and the latter more elongate than in most species. Length of lateral lobe in P. albitarsis 1.15 mm, P. viridimicans 1.50 mm.
Surface ornamentation: pronotum generally smooth and shining, and somewhat glabrous (males may have small patch of whitish hairs laterally; and in P. longipennis disc with sparse erect hairs; elytra glabrous. Underside generally less pubescent in females; in males clothed with suberect, moderately long, whitish pubescence (becoming untidy towards sides of prosternum, recumbent and dense on basal half of metasternum and sides of meso- and metathorax). Abdomen in female more glabrous; in males rather sparsely clothed with short pubescent (less sparse towards sides), with longer suberect hairs on basal urosternites; dense white patches of recumbent pubescence covering apico-lateral margins of urosternites I-IV (in P. albitarsis and P. viridimicans ), these patches absent (in P. nappae , and in females).
Puncturation of dorsad alveolate and dense, as follows: on vertex of head small and rugose (except for narrow smooth line at midline); on pronotum small and dense (but not rugose), without larger punctures (in P. viridimicans ), with larger punctures on lateral calli (in P. nappae ), or spreading from lateral calli to median callus (in P. albitarsis ). Puncturation on elytra generally small, subalveolate and dense (except on translucent panels and humero-apical costa); becoming somewhat rugose adjacent to humero-basal margin, sparser, simpler and shallower on translucent panels. Underside puncturation hardly hidden by pubescence; subalveolate, dense and small (lacking significantly larger punctures), and embedded in matrix of micropunctures, as follows: on prosternum smooth and carinate anteriorly, densely punctate posteriorly; on mesosternum similar to prosternum; in males metasternal punctures becoming scabrous where mixed with small tubercles, in females the puncturation becoming granulate. On abdomen punctures small, shallow and somewhat beveled; generally sparse to moderately sparse (in P. nappae ), or rather dense (in P. albitarsis and P. viridimicans ).
The species included in this genus are: Paraphygopoda albitarsis ( Klug, 1825) , Paraphygopoda nappae sp. nov., Paraphygopoda viridimicans ( Fisher, 1952) ; and, provisionally, Paraphygopoda longipennis ( Zajciw, 1963) .
Comment: in the original description by Zajciw (1963) of Epimelitta longipennis ( Fig. 9 View FIGURES 8‑14 ) he remarks that the coxae lack distinct tubercles; without examining this species, the author assumes that, at least, vestigial tubercles are present on the procoxae.
