Abdominal ventrites reddish brown, with irregular yellowish-brown and orangish-brown areas interspersed.

Head.

Genae distinctly shorter than lower eye lobe; with sparse whitish pubescence except glabrous apex. Postclypeus with sparse, somewhat bristly whitish pubescence, with a few long, erect yellowish-brown setae interspersed, except glabrous apex of sides. Anteclypeus with anterior and lateral margins elevated, glabrous. Labrum with long, erect yellowish-white setae not obscuring integument, setae more abundant laterally, and fringe of yellowish-brown setae on anterior margin. Antennal tubercles sparsely, finely punctate, except smooth apex; with a few short, decumbent yellowish setae, except glabrous apex. Gulamentum moderately abundantly and finely punctate on anterior third, transversely striate about central region, smooth on remaining surface; with a few setae on punctate area, glabrous on remaining surface. Distance between upper eye lobes 0.43 times distance between outer margins of eyes; in frontal view, distance between lower eye lobes 0.43 times distance between outer margins of eyes. Antennae 2.5 times elytral length, reaching elytral apex at apex of antennomere VI. Scape sparsely, moderately coarsely punctate; with sparse dark-brown pubescence on basal half; with suberect, both short and long yellowish setae interspersed dorsally, and long, erect dark-brown setae interspersed throughout. Remaining segments with minute brown pubescence, denser from antennomere IV; pedicel and antennomeres III–IV with sparse, erect dark-brown setae dorsally; pedicel and antennomeres III–VII with long, erect dark-brown setae ventrally, setae gradually sparser toward VII. Antennal formula (ratio) based on length of antennomere III: scape = 0.64; pedicel = 0.26; IV = 0.57; V = 0.92; VI = 1.01; VII = 0.89; VIII = 0.79; IX = 0.72; X = 0.67; XI = 0.74.

Thorax. Prothorax distinctly longer than wide; sides slightly rounded from anterolateral to posterolateral angles. Pronotum abundantly, finely punctate except smooth tubercles; with minute, erect yellowish-white pubescence not obscuring integument, absent on smooth areas, except dark-brown pubescence on dark anterior area; with long, erect yellowish-white setae interspersed. Sides of prothorax abundantly, finely punctate; with minute, erect yellowish-white pubescence not obscuring integument, and long, erect setae of same color interspersed. Posterior 2/3 of prosternum abundantly, moderately finely punctate; with abundant yellowish-white pubescence not obscuring integument; anterior third, smooth, glabrous, shiny. Narrowest area of prosternal process about 0.15 times procoxal width. Ventral surface of meso- and metathorax with whitish pubescence not obscuring integument, except dense pubescence close to metacoxae; metanepisterna and metaventrite with long, erect pale-yellow setae interspersed. Narrowest area of mesoventral process 0.58 times mesocoxal width. Scutellum with sparse whitish pubescence, except dense pubescence close to apical margin. Elytra. Almost reaching apex of first abdominal segment, longer than twice humeral width; moderately abundantly, coarsely punctate; with wide, dorsally rounded carina from humeri to near apex; with sparse, both short and long, erect yellowish-white setae, long setae more abundant dorsally close to anterior region of suture. Legs. Femora with sparse, long, erect yellowish setae; ventral surface of base of profemora with abundant, bristly yellowish setae; peduncle of mesofemora with moderately abundant, decumbent, short yellowish setae; peduncle of metafemora with sparse, decumbent, short yellowish setae. Tibiae with sparse, erect, brown setae, more abundant on metatibiae; ventral surface of protibiae with dense, bristly dark-brown pubescence; ventral surface of mesotibiae with long, suberect yellowish-brown setae. Dorsal surface of tarsi with brown pubescence not obscuring integument.

Abdomen. Ventrites smooth, with sparse, short, decumbent yellowish setae, and long, erect setae of same color interspersed. Apex of ventrite 5 distinctly notched centrally.

Female ( Figs 5–9 ). Similar to males, differing especially by the tarsomeres slender and not tumid and the apex of abdominal ventrite 5 rounded.

Dimensions in mm (holotype male/ paratypes male/ paratypes female). Total length (measured from anterior margin of the head to the apex of the abdomen), 11.00/8.75–10.30/11.30–11.80; prothoracic length, 1.85/1.75– 1.90/1.90–1.95; anterior prothoracic width, 1.21/1.10–1.25/1.30; posterior prothoracic width, 1.30/1.20–1.35/1.45– 1.50; maximum prothoracic width; 1.50/1.35–1.50/1.50–1.60; humeral width, 1.65/1.45–1.70/1.80–1.85; elytral length, 3.75/3.40–3.95/3.75–3.85.

Type Material. Holotype male from BOLIVIA, Santa Cruz: Laguna Esmeralda, 2100 m, 24.XI.2023, J. Vlasak col. ( MZSP) . Paratypes — 3 males and 2 females, same data as holotype . One paratype female ( Figs 5–8 ) deposited in MZSP, remaining paratypes ( Figs 9–12 ) in JVCO .

Etymology. The specific epithet boliviensis refers to Bolivia, the country where the type series was collected.

Remarks. Katerinaella boliviensis sp. nov. can be separated from K. costaricensis Vlasak & Santos-Silva, 2018 by the features listed in the key:

1. Prothorax distinctly widened from anterior third toward middle; elytral length slightly shorter than twice humeral width; membranous wings entirely dark; metatibiae entirely dark. Costa Rica........ K. costaricensis Vlasak & Santos-Silva, 2018

– Prothorax slightly rounded from anterolateral angles to posterolateral angles; elytra longer than twice humeral width; membranous wings with large yellow macula; metatibiae with large yellow or yellowish-brown central ring.
