(Fig. 5–9)
Description. Female. Integument mostly dark brown; anteclypeus reddish-brown; distal half of labrum yellowish-brown; most of mouthparts reddish-brown, with palpi almost black except yellowish apex of each segment; antennomere III dark reddish-brown basally, gradually darkening to darker brown apex; antennomere IV reddish-brown basally, brownish on wide central area, dark brown on apex; antennomeres V–X light reddish-brown, gradually slightly darkened on wide central area, dark brown on apex (this latter area gradually smaller and less conspicuous toward X); antennomere XI light reddish-brown; apex of abdominal ventrites I–IV narrowly yellowish-brown. Pubescence pale-yellow (more whitish or golden depending on angle of light source).
Head. Frons coarsely, sparsely punctate; pubescence moderately abundant, not obscuring integument; with long, erect dark seta emerging from nearly all punctures, and close to eyes. Area between antennal tubercles with sculpturing, pubescence, and erect setae as on frons. Area between upper eye lobes with row of punctures, slightly coarser than on frons, on each side of central groove; pubescence as on frons; with a long, erect dark seta emerging from some punctures. Remaining surface of vertex minutely punctate; pubescence sparser than on frons; without erect setae. Area behind eyes minutely punctate (less so behind lower eye lobes); pubescent close to eye, nearly glabrous close to prothorax; with a few long, erect dark setae close to lower eye lobe. Genae very finely, transversely striate; with sparse pubescence close to eye, glabrous toward apex. Antennal tubercles impunctate; pubescence as on frons; with a few long, erect dark setae. Median groove distinct from clypeus to area between antennal tubercles, just indicated from this point to prothorax. Postclypeus coarsely, sparsely punctate in center, slightly rugose in remaining wide central area, smooth laterally; pubescence as on frons in wide central area, gradually sparser toward anteclypeus, glabrous in smooth area; with long, erect, sparse dark setae in pubescent area (one very long on each side). Labrum coplanar with anteclypeus in basal 2/3, inclined at distal third; minutely, abundantly punctate, with interspersed slightly coarser punctures at apex of basal 2/3; with sparse pubescence interspersed with long, erect dark setae directed forward; with fringe of golden setae at apex. Gulamentum smooth, glabrous toward prothorax, finely punctate, sparsely pubescent, with a few long, erect setae toward mouthparts. Distance between upper eye lobes 0.39 times length of scape; in frontal view, distance between lower eye lobes 0.78 times length of scape. Antennae 1.4 times elytral length, reaching elytral apex at base of antennomere XI; scape slightly widened toward apex; moderately coarsely, sparsely punctate; pubescence not obscuring integument, interspersed with long, erect dark setae; antennomeres III–X with long, erect dark setae ventrally (gradually shorter, sparser toward X), and long, erect dark setae at dorsal apex (shorter toward X); Antennal formula (ratio) based on antennomere III: scape = 0.93; pedicel = 0.22; IV = 0.95; V = 0.82; VI = 0.73; VII = 0.67; VIII = 0.58; IX = 0.53; X = 0.42; XI = 0.47.
Thorax. Prothorax 1.5 times wider than long (including lateral tubercles); lateral tubercles moderately large, conical, nearly acute at apex, placed at about middle. Pronotum with large, subcircular, slightly distinct gibbosity on each side of distal half, and elongate, slightly elevated gibbosity at center of basal half; coarsely, sparsely punctate except on smooth central gibbosity; pubescence moderately abundant, not obscuring integument; with long, erect dark setae emerging from some punctures. Sides of prothorax smooth between base and lateral tubercle, coarsely punctate close to pronotum between lateral tubercle and narrow, smooth distal area; pubescence moderately abundant, not obscuring integument; with long, erect dark setae emerging from some punctures. Prosternum very finely rugose, with interspersed fine punctures; pubescence not obscuring integument; with long, erect dark setae toward prosternal process; prosternal process noticeably narrowed centrally. Ventral side of meso- and metathorax with pubescence not obscuring integument, slightly sparser centrally. Mesoventral process slightly longitudinally elevated centrally; apex emarginate. Scutellum with yellow pubescence, denser toward margins. Elytra. Coarsely, abundantly punctate (slightly finer, sparser toward apex); pubescence abundant, not obscuring integu- ment; with long, erect, dark setae emerging from punctures; apex rounded. Legs. Femora moderately finely, sparsely punctate; pubescence abundant, not obscuring integument; with a few long, erect dark setae. Tibiae slightly, gradually widened toward apex; with abundant, long erect, dark and yellowish setae, especially dorsally on meso- and metatibiae. Metatarsomere I slightly shorter than II–III together.
Abdomen. Pubescence abundant, not obscuring integument; apex of ventrite V truncate.
Dimensions in mm (holotype female). Total length 7.55; prothoracic length 1.45; basal prothoracic width 1.70; distal prothoracic width 1.50; max. prothoracic width 2.15; humeral width 2.70; elytral length 5.45.
Type material. Holotype female from BOLIVIA, Santa Cruz: Potrerillo del Guendá (350–400 m; 17°40 ʹ S / 63°27 ʹ W), 7-9.IX.2012, J. Wappes, P. Skelley and T. Bonaso col. (FSCA).
Etymology. Named to honor B. K. “Byrd” Dozier, an avid lifetime collector of beetles (especially the Buprestidae and Cerambycidae), whose most favorite collection locality in Bolivia is Potrerillo del Guenda, the type locality of this species (Note: in February of this year Byrd celebrated his 91 st Birthday!)
Remarks. Drycothaea dozieri sp. n. differs from D. angustifrons (Breuning, 1943) by the distance between upper eye lobes wider than width of one upper lobe (at most equal to width of an upper lobe in D. angustifrons), and tubercle of mesoventral process not forming elevated keel (forming elevated keel in D. angustifrons). The new species differs from D. viridescens (Buquet, 1857) by the mesoventral process without an elevated central tubercle (Fig. 6) (tubercle present in D. viridescens (Fig. 10)).
Drycothaea dozieri sp. n. can be included in the alternative of couplet “22” from Galileo and Martins (2010):
22 ʹ (21). Mesoventral process without distinct elevated tubercle; Bolivia .............................................. D. dozieri Wappes, Santos-Silva and Galileo, new species
— Mesoventral process with distinct elevated tubercle................................ 22
22(22 ʹ). Elytral punctures separated, those of row close to suture, at central area, separated by distance equal to twice the diameter of a puncture; punctures of distal area of the elytra sparse; Venezuela .......................................... D. estola (Lameere, 1893)
— Elytral punctures of the row close to suture, at central area, separated by distance equal to diameter of a puncture; punctures of distal area of the elytra not distinctly sparse; Brazil (Bahia, Espírito Santo, Rio de Janeiro, São Paulo, Santa Catarina), Paraguay, Argentina (Misiones)....................................... D. viridescens (Buquet, 1857)
