Muisca  SPINOLA, 1844b: 147.

EKIS (now OPITZ) 1975: 54. OPITZ 2010: 100; 2017a: 69. See CORPORAAL (1950: 198) for historical citations.

Type species: Muisca bitaeniata  SPINOLA, 1844b:148. By monotypy.

Junior synonym: Paragregya PERACCHI, 1964: 115.

D i a g n o s i s: Muisca  has an oblong pronotum, which this genus shares with the Neotropical genera Ambitus, Apolopha, Crusbatus, Merickelus, Neotenerus, Ramosus, and Tanycorpus, but Muisca  specimens differ by having a comparatively short capitulum when compared with the capitulum of the members of the other aforementioned genera. Also, peloniine specimens belong to this genus if they show an oblong pronotum (discounting the width measure provided by the lateral tubercles) in combination with exceedingly long pronotal projections ( Figs 5View Figs 2-13, 89View Figs 88-89).

A p o t y p i c c h a r a c t e r i s t i c s: Pronotal projections long.

R e d e s c r i p t i o n: Size: Length 4.0-11.0 mm; width 1.5-5.0 mm. Form ( Fig. 1): Oblong, hind body may be suboval, body not particularly deep, about 2 times longer than broad. Vestiture: Dorsum profusely vested with pale setae; antenna moderately setose;

elytra with 1º and 2º setae. Head ( Figs 2-4View Figs 2-13, 80View Figs 80-81): Cranium subquadrate, frons usually wider than width of eye, indented with coarse setiferous punctations; gula ( Figs 3View Figs 2-13, 82View Figs 82-83) large, triangular, sutures sinuous, gula with two well-developed setose gular processes ( Fig. 83View Figs 82-83); labrum ( Fig. 9View Figs 2-13) shallow, incised distally, tormal processes confluent, epipharyngeal plate small; mandible ( Fig. 11View Figs 2-13), body stout and, anterior dens acuminate, medial dens well developed, posterior dens poorly developed, penicillus well developed; maxilla ( Fig. 8View Figs 2-13), laterolacinia well developed, terminal palpomere subfiliform to subsecuriform; labium ( Fig. 12View Figs 2-13), ligula deeply incised, ligular lobes narrowed, terminal palpomere subsecuriform; eyes large, coarsely facetted, ocular notch moderately sized; antenna ( Figs 6View Figs 2-13, 84View Figs 84-85) comprised of 11 antennomeres, capitate, funicular antennomeres from filiform to subfiliform, capitulum usually longer than combined length of funicular antennomeres. Thorax: Pronotum ( Figs 86View Figs 86-87, 88View Figs 88-89) usually oblong, rarely quadrate, anterior limit of dorsolateral carina extends to, but does not connect with, anterior pronotal margin, disc slightly convex, side margins with well-developed tubercle ( Fig. 87View Figs 86-87), prointercoxal process narrow ( Fig. 89View Figs 88-89), slightly expanded distally; pronotal projections long, acuminate, approximates prointercoxal process; elytron profusely sculptured with asetiferous punctations ( Fig. 85View Figs 84-85) in basal half, epipleural fold wide, ends abruptly at about elytral distal 3/4 th, elytral anterior margin not carinate; metathoracic wing as in Fig. 13View Figs 2-13, wedge cell not closed; metendosternite ( Fig. 10View Figs 2-13) with furcal lamina, furcal anterior plate wide; legs, profemora posterior margin without spines, tibial spur formula 1-2-2, tarsal pulvillar formula 3-3-3, unguis ( Figs 90, 91View Fig) with basal denticle. Abdomen: Aedeagus, phallobase lobed, lobes minutely fimbriate, tegmen very reduced, submembranous, phallobasic struts not confluent with phallobasic apodeme, phallobasic rod very short, phallic plates narrow; spicular plates flared ( Fig. 7View Figs 2-13), spicular apodemes fused near middle; ovipositor shorter than abdomen, laminae acuminate, laminal rod present. Alimentary Canal ( Fig. 45View Figs 34-46): Proventriculus well developed; ventricular crypts poorly defined; 4 cryptonephridial Malpighian tubules. Mesodermal Male Internal Reproductive Organs ( Fig. 46View Figs 34-46): Two pairs of accessory glands; ejaculatory duct greatly elongated.

D i s t r i b u t i o n: The geographical range of this Neotropical genus extends from Costa Rica to Brazil.
