Type material. Holotype ♂ ( Fig. 1 ): “ Boliv .// Guérin// paradoxa Stål // typus// NHRS-GULI / 000065262 ” ( NHRS ). The specimen is considered a holotype by monotypy (ICZN, art. 73.1.2). Type locality. Bolivia. Remarks. The original description is an abbreviated series of remarks on the coloration of the new species ( Stål, 1866b ). Description. Head, pronotum and mesonotum tawny (castaneous in holotype ), abdomen tawny. Body covered by blond setae and small spines. Head ( Figs. 2 A–C; 4A). Head about as wide as mesonotum, tawny (castaneous in holotype ), triangular, with transverse piceous fascia along supra–antennal plates. Eyes castaneous, ocelli rosaceous. Ocular tubercle marked with piceous. Posterior margin of eyes with a black stain and pile setae. Supra–antennal plates prominent relative to anterior margin of head and not meeting eye.Ventral head light brown with transverse piceous fascia between eye and supra–antennal plate. Postclypeus light brown with ten tawny transverse grooves, marked with piceous along medial transverse grooves on either side of midline, blond setae and small spines, central sulcus narrow. Anteclypeus tawny, posterior margin covered with blond setae. Mentum ochraceous, labium ochraceous striped with castaneous with piceous tip reaching middle abdominal sternite I. Proximal scape ochraceous, pedicel castaneous. Thorax ( Figs. 2A, D ; 4A, B ). Pronotum tawny (castaneous in holotype ) covered by blond setae and small spines, two piceous longitudinal fasciae along the median and sub-lateral lobes. Lateral fissures marked with piceous. Pronotal collar tawny, lateral margin convex, lateral angle pronounced and projected laterally, wider than mesonotum lateral margin. Mesonotum tawny (castaneous in holotype ), wing groove tawny. Cruciform elevation centrally swollen, the surface of posterolateral projections flat, not covering first abdominal tergite completely. Operculum ( Figs. 2E ; 4C ). Male operculum ochraceous semilunar with anterior margin straight and base angled posteromedially, posterior margin slightly convex, lateral margin convex, internal angles separated by swelling of abdominal sternite I. The female operculum ochraceous, with medial margin straight and lateral margin short and convex. Wings ( Figs. 2A ; 4A ). Wings hyaline with semi opaque appearance; costal vein strongly arched and widened at base, the expanded proximal costal margin forming an arc bringing the leading edge of the forewing almost to the apex of the postclypeus.Veins tawny marked with castaneous. Forewings with eight apical cells, nine apical cells in one wing of male, infuscation on radial, radiomedial, medial and mediocubital crossveins and on proximal radius anterior 2, radius posterior distal to junction of radiomedial crossvein, proximal median vein 1 and proximal median vein 2, linear infuscation within apical cells terminating in spot on ambient vein, light infuscation delineating nodal line. Basal cell opaque, subcylindrical longer than broad. Hindwings with six apical cells, cubital cell 1 widening distally to base of apical cell 6, venation tawny with castaneous anal veins 2 and 3, anal vein 3 curved at distal terminus. Jugal fold short, not extending to half length of anal lobe. White along proximal cubitus posterior, proximal anal veins 1 and 2 and along anal vein 3, anal cell 3 white. Legs ( Fig. 2D, E ; 4C ). Coxae, trochanters, and femora tawny with blond setae, castaneous at apex. Fore femora with castaneous markings and narrow posterolateral region covered by blond setae towards fore tibia. Fore femora with two spines, primary spine in horizontal position in relation to femur, close to femur, secondary spine largest and darker, a right angle to femoral axis. Tarsi castaneous marked with piceous. Pretarsal claws castaneous with piceous tips. Male meracanthus ochraceous, an elongated triangle, short, not reaching middle of operculum. Female meracanthus ochraceous, an elongated triangle, extending over anterior margin of operculum. Abdomen ( Figs. 2A, F, G ; 4A, D, E ). Abdomen tawny, subcylindrical, anterior margin of tergites with blond setae. Timbal cover flat, dorsolateral margin concave exposing dorsal timbal, apex acutely angled almost reaching lateral metascutellar plate, lateral margin meeting the lateral margin of operculum. Male sternites tawny, sternite II with anterior and posterior margins arched anteriorly with blond setae, sternite VII sub-rectangular longest of male sternites, lateral margins concave in anterior sternites becoming convex in posterior sternites, posterior margin slightly emarginated, sternite VIII ovoid with blond setae at apex. Female tergite 9 with the posterior margin slightly convex in lateral view, ventral margins almost straight. Female sternites tawny covered by blond and white setae, sternite VII with the posterior margin sinuous with an obtuse groove in the middle portion, the dorsal beak shorter than the ovipositor sheath in lateral view. Epipleurites tawny, medial region reflexed dorsally. FIGURE 3. Nosola paradox a Stål, 1866 , male genitalia.

Pygofer subcylindrical; pygofer distal shoulder anterior margin terminating in acute projection sclerotized at apex; pygofer basal lobe short, not reaching mid-length of pygofer, rounded apex, not clearly delimited from lateral pygofer margin. Uncus slightly longer than basal lobe in lateral view; uncal dorsal crest projected posteriorly fused on midline; median uncus lobe undeveloped but present, bud-like; lateral margins of lateral branches of uncus slightly concave; anterior margins of ventral apophyses straight, lateral margins slightly convex. Theca a long tube with a long vesica and extruded sclerotized cornuti in two rows ventrally. Vesica slender slightly inflating toward apex; apex of vesica with central spine and clustered cornuti almost forming a spiral. Female dorsal beak tawny, shorter than the tip of the ovipositor sheath in lateral view. Gonapophyses IX and ovipositor sheath castaneous, blond setae at apex of ovipositor sheath. FIGURE 4.
