description: Recchia volcanensis sp. nov.
(Figs. 30, 34–36)
Description. Female. Integument dark-brown, almost black.
Head. Frons finely, abundantly punctate (punctures slightly coarser, denser laterally); with short, abundant, erect, yellowish-brown setae (not obscuring integument, but denser close to antennal tubercles) interspersed with long, erect, yellowish-brown and brown setae. Antennal tubercles with sculpture as on frons, slightly finer toward apex; with yellowish-brown, decumbent setae (partially obscuring integument, slightly lighter than on frons), interspersed with long, erect, yellowish-brown setae. Area between antennal tubercles and upper eye lobes finely, abundantly punctate (punctures slightly coarser than on frons); with setae as on antennal tubercles. Area between posterior margin of upper eye lobes and prothoracic margin moderately finely, abundantly punctate; with short, decumbent, yellowish-brown setae, almost obscuring integument, interspersed with long, erect, yellowish-brown setae. Tempora with sculpture and setae as on area of vertex close to prothorax, but with long, erect setae distinctly sparser. Genae with short, sparse, yellowish-brown setae interspersed with long, erect setae on area close to submentum; remaining surface smooth, glabrous. Postclypeus opaque, finely, moderately abundantly punctate, except for smooth lateral regions; with short, abundant, yellowish-brown setae (not obscuring integument) interspersed with long, erect, yellowish-brown setae. Labrum finely, sparsely punctate on basal quarter, densely, partially confluently punctate on distal 3/4; with short and long, abundant, erect, yellowish-brown setae. Longitudinal sulcus distinct from clypeus to prothoracic margin. Upper eye lobes distinctly widened after antennal socket; distance between upper eye lobes 0.2 times length of scape; distance between lower eye lobes in frontal view 0.4 times length of scape. Antennae 1.7 times elytral length, reaching elytral apex at basal quarter of antennomere IX. Antennal formula based on antennomere III: scape = 1.38; pedicel = 0.19; IV = 0.86; V = 0.78; VI = 0.81; VII = 0.78; VIII = 0.73; IX = 0.65; X = 0.59; XI = 0.62.
Thorax. Prothorax slightly widened from base to apex. Pronotum finely, abundantly punctate; disc with yellowish-brown setae, partially obscuring integument, more whitish on base and part of narrow lateral band; setae forming somewhat bristly longitudinal central band, and longitudinal, slightly distinct, lateral band at each side (less distinct toward anterior margin); lateral area with setae distinctly shorter and less conspicuous; with long, erect, sparse setae throughout. Sides of prothorax finely, abundantly punctate; with short, decumbent, abundant, yellowish-brown setae, partially obscuring integument, interspersed with long, erect setae, except narrow band close to anterior margin with setae distinctly shorter and less conspicuous (this area narrowed toward pronotum). Prosternum, moderately finely, abundantly punctate, except area close to anterior margin with punctures finer and sparser; with short, abundant, yellowish-brown setae interspersed with long, erect setae on area more distinctly punctate, less conspicuous close to anterior margin. Prosternal process with long, erect, abundant yellowish-brown setae, except distal area with setae more whitish, directed backward. Sides of ventral side of mesothorax, metepisternum and sides of metasternum with moderately dense, decumbent, whitish setae (more yellowish toward apex of metasternum); remaining surface with yellowish-brown, decumbent setae; with long, erect, sparse, yellowish-brown setae (more abundant on mesosternum); metepisternum and sides of metasternum coarsely, moderately abundantly punctate; remaining surface of metasternum minutely, abundantly punctate. Scutellum with decumbent, abundant, yellowish-brown setae. Elytra. Coarsely, abundant punctate on basal 2/3, distinctly finer, sparser on distal third; dorsal surface with central sub-triangular large macula with whitish, decumbent setae, almost reaching apex of basal third, except for narrow sutural band with yellowish-brown setae; sides of basal 2/3 with band of whitish setae, sub-right, more lateral on basal third, curved toward dorsal side, forming semi-circle on middle third; distal 2/5 with longitudinal band with white pubescence, not reaching apex and suture, sub-right, more lateral on its distal third, oblique toward suture on anterior 2/3; distal fifth with longitudinal band with white pubescence near and subparallel to suture; remaining surface with yellowish-brown, decumbent setae (partially obscuring integument); with long, erect, sparse, yellowish-brown setae throughout; apex moderately widely, individually rounded. Legs. With yellowish-brown setae, not obscuring integument, interspersed with long, erect, yellowish-brown setae (more abundant on tibiae); metatarsomere I 1.25 times longer than II–III together.
Abdomen. Ventrite I moderately finely and abundantly punctate (less so centrally); ventrites II–V finely, sparsely punctate; with yellowish-brown, decumbent, abundant setae, partially obscuring integument (somewhat bristly on longitudinal, narrow, central band on ventrite I), interspersed with long, erect, sparse, yellowish-brown setae; distal margin of ventrite V slightly concave.
Dimensions (mm). Holotype female. Total length, 11.50; prothoracic length, 1.80; anterior prothoracic width, 2.00; posterior prothoracic width, 1.75; humeral width, 2.65; elytral length, 8.40.
Type material. Holotype female from BOLIVIA, Santa Cruz: 4 km N Bermejo (Refugio Los Volcanes; 18º06’S / 63º36’W; 1045–1350 m), 17–24.X.2014, Wappes & Morris col. (MNKM).
Etymology. The epithet “ volcanensis ” refers to the type locality of the holotype (Refugio Los Volcanes).
Remarks. Recchia volcanensis sp. nov. differs from R. abauna Martins & Galileo, 1998 by the upper eye lobes distinctly wider, with more than 10 rows of ommatidia (Fig. 30), by the pubescence on basal third of elytral disc not forming band, by the distal sixth of the elytra not entirely with whitish pubescence. In R. abauna the upper eye lobes are narrower, with 5-6 rows of ommatidia (Fig. 37), the pubescence on basal discal third of the elytra forms band, the distal sixth of the elytra is entirely covered with whitish pubescence. It differs from R. distincta (Lane, 1939) mainly by the upper eye lobes wider and with finer ommatidia (narrower and with coarser ommatidia). It can be separated from R. lanei Martins & Galileo, 1985 (Fig. 39) by the upper eye lobes wider (narrower in R. lanei - Fig. 31) and by the pubescence forming different drawings on the elytra (Fig. 34). It differs from R. ludibriosa Lane, 1966 and R. moema Martins & Galileo, 1998 mainly by the pubescence forming different drawings on the elytra (see photographs of the holotypes of R. ludibriosa and R. moema at Bezark 2016). Finally, it differs from R. procera Martins & Galileo, 1985 (Fig. 38) by the body wider, by the upper eye lobes wider (narrower in R. procera (Fig. 32)), and by the elytral apex distinctly wider and rounded (Fig. 34) (more acuminate in R. procera (Fig. 33)).
