( Fig. 15–19View Figures 11–19)

Description. Male. ( Fig. 15–18View Figures 11–19). Integument mostly dark brown; anteclypeus testaceous; labrum dark reddish-brown; mouthparts reddish-brown with apex of palpomeres yellowish-brown; basal 2/3 of antennomeres IV–VI reddish-brown; basal 2/3 of antennomeres VII–X yellowish-brown; antennomere XI mostly yellowish-brown, with reddish-brown ring from about middle to distal quarter; tarsomere V dark reddish-brown (browner depending on light intensity).

Head. Frons coarsely, abundantly punctate; with yellowish-brown and brownish pubescence not obscuring integument, denser on some areas, sparser in others, with short white setae interspersed. Vertex and superior area behind upper eye lobes coarsely, moderately abundantly punctate, forming distinct V-shaped punctate area toward prothoracic margin; remaining surface of area behind upper eye lobes coarsely, sparsely punctate close to eye, smooth on remaining surface; area behind lower eye lobes coarsely, sparsely punctate; area between antennal tubercles with yellowish-brown pubescence partially obscuring integument, with short white setae interspersed; area close to upper eye lobes with yellowish-brown pubescence, gradually sparser approaching area behind eye; area between upper eye lobes with yellowish-brown pubescence centrally; remaining surface of vertex and area behind upper eye lobes with abundant, brownish pubescence but not obscuring integument, with a few short white setae interspersed; area behind lower eye lobes with brown and yellowish-brown pubescence mixed, with a few short, white setae interspersed. Genae slightly shorter than length of lower eye lobe; finely, sparsely punctate toward frons, slightly coarser toward posterior area; pubescence as on area behind lower eye lobes. Antennal tubercles with inner projection distinctly elevated; together, in frontal view, U-shaped; sculpturing as on frons; with yellowish-brown and brown pubescence partially obscuring integument. Wide central area of postclypeus with sculpturing and pubescence as on frons, smooth and glabrous laterally. Labrum with short, sparse yellowish-white pubescence close to anteclypeus; with long, moderately abundant, decumbent, nearly golden setae on remaining surface. Mandibles with abundant yellowish-brown pubescence on basal half of outer surface, glabrous on remaining surface. Distance between upper eye lobes 0.36 times length of scape; in frontal view, distance between lower eye lobes 0.72 times length of scape. Antennae 1.85 times elytral length, reaching elytral apex at near apex of antennomere VIII. Scape with light yellowish-brown and brown pubescence mixed, partially obscuring integument, with short white setae interspersed (more abundant laterally and ventrally); pedicel with brown pubescence nearly obscuring integument; antennomere III with pubescence as on scape, except distal area with brown pubescence; antennomeres IV–X with yellowish-white pubescence on light area, brown on dark area; antennomere XI with yellowish-white pubescence; pedicel and antennomeres III–VI with a few long, erect, thick dark setae ventrally (sparser toward VI). Antennal formula (ratio) based on length of antennomere III: scape = 0.92; pedicel = 0.24; IV = 1.41; V = 1.15; VI = 1.11; VII = 0.92; VIII = 0.85; IX = 0.78; X = 0.74; XI = 0.79.

Thorax. Prothorax slightly wider than long; sides constricted both anteriorly and posteriorly, with small, rounded tubercle at posterior third. Pronotum coarsely, abundantly punctate; with three longitudinal yellowish-brown pubescent bands, one centrally, wider about middle, one on each side, denser basally and posteriorly, partially fragmented on wide central area; remaining surface with brownish pubescence not obscuring integument; with short, sparse white setae interspersed throughout. Sides of prothorax with sculpturing as on pronotum, slightly denser dorsally; with longitudinal yellowish-brown pubescent band close to pronotum, with short white setae interspersed, brownish pubescence centrally, with small white setae interspersed, and yellowish-brown pubescence close to prosternum, with small white setae interspersed; with a few long, erect dark setae posteriorly near pronotum. Prosternum with yellowish-brown pubescence not obscuring integument, with white setae interspersed. Narrowest area of prosternal process 0.25 times width of procoxal cavity. Mesanepisternum, mesepimeron and sides of mesoventrite with dense yellowish-brown pubescence; central area of mesoventrite with dense yellowish-white pubescence; mesoventral process with dense white pubescence. Distal area of mesoventral process about 0.5 times width of mesocoxal cavity. Metanepisternum and sides of metaventrite with yellowish-white pubescence, with white setae interspersed; wide central area of metaventrite with abundant white pubescence. Scutellum with yellowish-brown pubescence not obscuring integument, absent along almost entire longitudinal center, with white setae interspersed. Elytra. Surface irregular, with irregular longitudinal carinae; humeri rounded, not projected; coarsely (punctures finer than on pronotum), abundantly punctate on basal half, gradually finer, sparser on distal half; with dense yellowish-brown pubescent maculae and bands, with shorter brown pubescence interspersed, and with small, sparse white setae interspersed throughout. Legs. Femora with white pubescence basally on ventral surface, yellowish-brown, partially obscuring integument, with short white setae interspersed (meso- and metafemora with dorsal and lateral brown band near apex). Tibiae with yellowish-brown pubescence partially obscuring integument, with small white setae interspersed (meso- and metatibiae with irregular areas with only brown pubescence); metatibiae tumid.

Abdomen. Ventrite I mostly brown pubescent, with yellowish-brown pubescence interspersed, more abundant on posterocentral area; ventrites II–IV with abundant yellowish-brown pubescence, with white setae interspersed, and irregular areas with shorter, sparser brownish pubescence, except basal half of central area with dense yellowish-white pubescent macula; ventrite V not depressed centrally, with yellowish-brown pubescence on base and sides, with short white setae interspersed, except centrobasal area with dense yellowish-white pubescent macula, and sparser brown pubescence on remaining surface; apex of ventrite V slightly concave.

Female. ( Fig. 19View Figures 11–19). Antennae 1.5 times elytral length, reaching elytral apex at about distal third of antennomere IX; metatibiae not tumid, gradually widened toward apex; ventrite V somewhat depressed centrally.

Variation. Antennomere III reddish-brown on basal 2/3.

Dimensions (mm), holotype / paratypes female. Total length, 8.80/9.90–10.95; prothoracic length, 1.35/1.50–1.80; anterior prothoracic width, 1.45/1.70–2.10; posterior prothoracic width, 1.55/1.75–2.20; maximum prothoracic width, 1.60/1.80–2.35; humeral width, 2.25/2.55–3.10; elytral length, 6.25/7.10–8.10.

Type material. Holotype male from BOLIVIA, Santa Cruz: 4 km SSE Buena Vista (Hotel Flora and Fauna, 350–400 m; 17°29′S / 63°49′W), 22–25.XI.2013, Wappes and Skillman col. ( FSCA), formerly ACMTGoogleMaps  ). Paratypes – BOLIVIA, Santa Cruz: 4-6 km SSE Buena Vista (Flora and Fauna Hotel), 1 female, 3–8.X.2004, Wappes and Morris col. ( ACMT)  ; 3.7 km SSE Buena Vista (Hotel Flora and Fauna; 430 m), 1 female, 5–15.XI.2001, M. C. Thomas and B.K. Dozier col. ( MZSP)  ; 1 female, Buena Vista vic. Flora and Fauna Hotel , 22–26.X.2002, Morris / Wappes col. ( RFMC)  .

Remarks. Cacostola opitzi  sp. nov. is similar to C. variegata  (see photographs of the holotype at Bezark 2019a) by the lower eye lobes being shorter, slightly longer than the genae (nearly two and one-half times genal length in C. variegata  ), antenna shorter (distinctly longer in male of C. variegata  ), and metatibiae distinctly tumid (not so in male of C. variegata  ). It differs from C. clorinda  by the antennomere IV being distinctly longer than III (slightly longer in male of C. clorinda  ), antennomeres distinctly annulated (not so in C. clorinda  ), and elytra without a dark central band on the basal half (present in C. clorinda  ).

Etymology. Named for Weston Opitz, great friend of the first author, and the leading taxonomist of Cleridae  in the New World who goes to great lengths to be inclusive in his work. The first author is forever grateful for the more than 400 clerid paratypes (representing 80 plus species) that are in his collection and the direct result of Weston’s talents and “inclusive nature”.
