Eupromerella boliviana sp. nov. ( Figs. 147-151 )

Description: Female: Integument mostly black; mouthparts dark reddish-brown, except palpi black with reddish-brown apex of last palpomeres; antennomere III brown on basal ⅔, black on distal third (slightly reddish-brown on apical area); remaining antennomeres yellowish-brown on basal half/third, black on remaining surface; anteclypeus and labrum mostly testaceous.

Head: Frons finely, densely punctate; with yellowish-brown and pale-yellow pubescence intermixed, nearly obscuring integument, with yellowish-white setae interspersed, large yellowish-white pubescent macula between eyes and antennal tubercles centrally. Vertex finely, abundantly punctate; area between antennal tubercles with yellowish-white pubescence not obscuring integument centrally, with yellowish-white setae interspersed, and dense yellowish-white pubescence laterally; area between upper eye lobes and beginning of area behind upper eye lobes with yellowish-white pubescence not obscuring integument, with yellowish-brown setae interspersed, dense yellowish-brown pubescence on remaining surface, except brown pubescent macula between the two pubescent areas; area close to prothorax nearly glabrous; remaining surface area behind upper eye lobes close to eye with yellowish-brown and brown pubescence not obscuring integument, glabrous toward prothorax. Area behind lower eye lobes with sparse yellowish-white pubescence close to superior area of eye, denser toward ventral surface, distinctly sparser toward prothorax. Genae about as long as lower eye lobe; with yellowish-brown pubescence, denser close to eye, sparser on remaining surface. Postclypeus with bristly yellowish-brown pubescence on wide central area not obscuring integument, central area nearly glabrous laterally glabrous. Posterior ¾ of labrum coplanar with anteclypeus, inclined on anterior quarter; with abundant yellowish-white pubescence on coplanar area,becoming yellowish toward anterior margin. Gulamentum glabrous except narrow anterior area with yellowish-white pubescence not obscuring integument. Distance between upper eye lobes 0.73 times length of scape; in frontal view, distance between lower eye lobes 1.17 times length of scape. Antennae 1.6 times elytral length, reaching elytral apex at basal third of antennomere IX. Scape nearly straight at outer surface, strongly, gradually widened from base to middle of inner surface, then slightly narrowed toward apex; with yellowish-brown and brown pubescence mixed dorsally, not obscuring integument, except dense, narrow yellowish pubescent macula on apex; with yellowish-white pubescence not obscuring integument on remaining surface. Pedicel brown pubescent dorsally, with yellowish-brown pubescence interspersed, especially basally; remaining surface with yellowish-white pubescence not obscuring integument. Light area of antennomeres with yellowish-white pubescence (sparser on some areas of III), and dark brown pubescence on dark area; ventral surface of antennomeres III-IV with short,sparse,erect yellowish-brown setae; apex of antennomeres V-X with short, erect, brownish setae at apex. Antennal formula (ratio) based on length of antennomere III: scape = 0.78; pedicel = 0.24; IV = 0.87;V = 0.58; VI = 0.51;VII = 0.42;VIII = 0.37; IX = 0.36; X = 0.31; XI = 0.33.

Thorax: Lateral tubercle of prothorax large, conical, slightly curved upward, with apex nearly acute. Pronotum with large gibbosity on each side of central area, and slightly elevated central gibbosity on posterior half, becoming carina-shaped on anterior half; coarsely, densely punctate, except smooth posterior area of central gibbosity; with irregular tufts of light yellowish-brown pubescence (more pale yellow posteriorly), and moderately spare brown pubescence between them, except glabrous posterior area of central gibbosity; with a few long, erect dark setae on sides of posterior area. Sides of prothorax coarsely, abundantly punctate; with light yellowish-brown pubescence throughout. Ventral surface of thorax with moderately dense pale-yellow pubescence laterally, gradually spars- er, whiter centrally. Narrowest area of prosternal process slightly less than half width of procoxal cavity. Apex of mesoventral process about as wide as mesocoxal cavity. Scutellum with short brownish pubescence not obscuring integument, with yellowish-brown setae interspersed. Elytra: Coarsely, abundantly punctate on basal third, punctures gradually sparser on remaining surface toward apex; apex obliquely truncate; with dense light yellowish-brown pubescence nearly entirely obscuring integument, except: irregular, narrow, fragmented V-shaped (across both elytra) brownish pubescent area on center of basal third; small, irregular white pubescent spot on base of each arm of V-shaped area; large, irregular white pubescent macula dorsally on basal half; irregular, nearly triangular brown pubescent macula dorsally after middle, laterally margined with narrow, white pubescence, especially on outside edge; irregular, white pubescent macula dorsally on posterior quarter close to latter dark macula; small, irregular white pubescent spot near apex; narrow white pubescent macula along suture and epipleural margin (nearly absent on basal quarter of sutural area), with brown pubescent areas interspersed. Legs: Femora with yellowish-white pubescence on peduncle and basal area of club, remaining surface densely pale-yellow.Tibiae with yellowish-white pubescence, except two brown pubescent macula covering dorsal area and sides, one less conspicuous on basal third, another wider on posterior half (more conspicuous in protibiae). Tarsomeres I and V with yellowish-white pubescence dorsally (sparser on protarsomere I); tarsomeres II-IV with brown pubescence dorsally.

Abdomen: Ventrites with yellowish-white pubescence not obscuring integument, slightly yellower and denser on V; ventrite V centrally sulcate at basal third; apex of ventrite V truncate.

Dimensions (mm), holotype female/ paratype female: Total length, 6.30/6.25; prothoracic length, 1.25/1.20; anterior prothoracic width, 1.80/1.80; posterior prothoracic width, 1.80/1.80; maximum prothoracic width, 2.40/2.30; humeral width, 2.85/2.80; elytral length, 4.50/4.35.

Type material: Holotype female from BOLIVIA, Santa Cruz: Potrerillo del Guendá ( Reserva Natural , Snake Farm ; 400 m; 17°40′15″S, 63°27′26″W), 23-30.X.2013, Wappes & Kuckartz col. ( FSCA, formerly ACMT). Paratype female from BOLIVIA, Santa Cruz: Andrés Ibáñes ( Potrerillo del Guendá ; 370 m; 17°40′S, 63°27′W), 23-27.X.2007, S.W. Lingafelter col. ( SWLC) .

Remarks: Eupromerella boliviana sp. nov. is similar to E. plaumanni (Fuchs, 1959) but females differ as follows: size smaller; lower eye lobes proportionally smaller; femoral peduncle shorter; elytral pubescent pattern with posterior dark macula not arch-shaped; and metaventrite not punctate laterally. Females of E. plaumanni are larger, lower eye lobes are proportionally larger, femoral peduncle are longer, posterior dark macula of the elytra is arch-shaped, and the metaventrite is punctate laterally. The new species differs from E. picturata Martins, Galileo & Limeira-de-Oliveira, 2009 (females) by the smaller size, metaventrite not punctate laterally (punctate in E. picturata ), the pubescence of the scape is sparser (denser in E. picturata ), and posterior dark macula of the elytra not arch-shaped (arched in E.picturata ). Eupromerella boliviana also differs from E. propinqua (Melzer, 1931) , and E.pseudopropinqua (Fuchs, 1959) , by the different pubescent pattern of the elytra (see photographs of the types of those two species at Bezark, 2019).

Etymology: This species is named “boliviana” after the country (Bolivia) where it is found.
