description: Eurysthea llinasi sp. nov. (Figs. 1–6)
Description. Female. Head, meso- and metathorax, antennae, and legs light brown, with long, erect, sparse yellowish setae. Pronotum brown except dark-brown tubercles. Prosternum brown except light-brown anterior area (not including dark-brown anterior margin). Elytra light brown except yellow, inverted V-shaped band, from about apex of basal quarter to about middle (prolonged along suture to about posterior third), and almost V-shaped yellow band in posterior quarter; parts of V-shaped bands margined by dark-brown band. Apex rounded, slightly emarginated near suture and with inner spine.
Head. Frons with irregular punctures. Vertex concave between antennal tubercles, with abundant fine punctures close to margins. Antennal tubercles glabrous in base, punctate in apex. Distance between upper eye lobes 0.50 times length of scape; in frontal view, distance between lower eye lobes 0.85 times length of scape. With abundant yellowish setae around antennal socket. Genae with rounded apex, glabrous. Frontoclypeal sulcus indistinct. Clypeus truncate, glabrous. Labrum emarginate, with yellowish setae. Mandibles with long yellowish setae. Maxillary palpi brown, with yellowish setae laterally; palpomere III dilated at apex. Antennae 11-segmented; antennomeres unarmed, with long yellowish setae. Scape thickened toward apex. Antennomere III almost twice length of scape. Antennal formula (ratio) based on length of antennomere III: scape = 0.65; pedicel = 0.10; IV = 0.72; V = 0.80; VI = 0.66; VII = 0.70; VIII = 0.65; IX = 0.62; X = 0.50; XI= 0.40.
Thorax. Prothorax wider than long. Pronotum with five tubercles: Four subcircular, two anteriorly and two posteriorly, connected between them by glabrous carina; another central, glabrous, feebly elevated; area between tubercles with abundant yellowish setae. Lateral region of prothorax with anterior tubercle rounded, and median tubercle acute. Prosternum with transverse wrinkles, with abundant yellowish setae. Metanepisternum with abundant, long yellowish setae toward margins. Metaventrite with long yellowish setae, shorter and sparser centrally. Scutellum with wrinkles, and abundant yellowish setae laterally. Elytra. Apex rounded, with sutural spine. Legs. With long yellowish setae; femora slightly flattened. Abdomen. Ventrites with long, erect, sparse yellowish setae centrally, more abundant, thicker laterally; apex of ventrite V sub-rounded, slightly emarginate centrally.
Dimensions, female (in mm). Total length, 31.65; prothoracic length, 3.70; anterior prothoracic width, 3.70; posterior prothoracic width, 4.40; widest prothoracic width, 4.55; humeral width, 6.70; elytral length, 23.75.
Type material. Holotype, COLOMBIA, Quindío: Salento (Estación Biológica Estrella de Agua, 4°37'24''N / 75°25'51''W, 3010 m.s.n.m.) (Fig. 9), 1 female, 12.VIII.2003, colecta manual, O. Estrada col. (CIUQ).
Etymology. The new species is named in honor of Dr. Rodolfo Llinás Riascos for his global contribution in the field of neuroscience.
Remarks. Eurysthea llinasi sp. nov. resembles E. antonkozlovi, E. koepckei (Franz, 1956), E. latefasciata (Fonseca- Gessner, 1990), E. magnifica Martins, 1985, E. punctata (Fonseca-Gessner, 1990), E. robertsi (Fonseca-Gessner, 1990), E. subandina (Fonseca-Gessner, 1990), and E. tatianakozlovae by the elytral pattern. It differs from E. antonkozlovi and E. robertsi by the elytra without squamiform or lanceolate setae (present in E. antonkozlovi and E. robertsi); differs from E. koepckei, E. latefasciata, E. punctata, and E. subandina by the unarmed antennomere III (with spine in apex of basal antennomeres in those species). The new species differs from E. tatianakozlovae by the brown integument, the antennomere III without spine at inner apex (Fig. 5), and the apex of elytra obliquely inclined forward toward sutural angle and with only sutural spine (Fig. 6). In E. tatianakozlovae the integument is dark brown, the antennomere III has a minute spine at inner apex (Fig. 8), and the apex of elytra is obliquely inclined backward toward sutural angle and bispinose (Fig. 7). Eurysthea llinasi sp. nov. differs from E. magnifica by the elytral apices unarmed externally; in E. magnifica, the elytral apices have long external spines.
Eurysthea llinasi sp. nov. can be included in the alternative of couplet 7 from Botero & Santos-Silva (2017):
