ETYMOLOGY. The name is a combination of castane - (L., castanea, of the color of chestnuts) and - torquata (L., torquatus, adorned with a necklace or collar) in reference to the large castaneous male opercula found in this new species.

REMARKS. This is another tawny species marked with piceous and castaneous. It is very similar in general appearance and coloration to Carineta nigrafissura n. sp. of the Peruvian fauna but can be distinguished quickly by the head being narrower than the mesonotum in this new species.

DESCRIPTION. Ground color of greenish-tawny marked with piceous and castaneous. The variability of greenish in the paratypes suggests the fresh specimens may be greener than the majority of the type series since the last animal collected has a higher proportion of green.

Head. Head wider than mesonotum, ground color with castaneous surrounding median ocellus extending anteriorly to castaneous frons, castaneous surrounding lateral ocelli extending posteriorly to posterior head margin, marking reduced in some paratypes, piceous mark on medial margin of eye, ground color posterior to eye except castaneous along posterior head margin on medial half of posterior eye. Ocelli rosaceous, ochraceous in some paratypes, eyes castaneous. Dorsal head covered with short golden pile and radiating dense, long piceous pile, very dense around ocelli, long silvery pile posterior to eye. Ventral head ground color. Postclypeus ground color ventrally, castaneous dorsally and within medial anterior three transverse grooves with amount of marking decreasing in the posterior grooves, centrally sulcate from anterior to posteroventral margin to apex, with ten transverse ridges, covered with short silvery pile and radiating long piceous pile, denser on dorsal surface. Anteclypeus ground color. Ventral head and anteclypeus with short silvery and long white pile, radiating long piceous pile. Mentum ground color, labium ground color proximally with piceous distal region, margined proximally with castaneous, tip castaneous, reaching to hind coxae. Antennal segments castaneous with ground color distal margin of scape, proximal pedicel and distal pedicel.

Thorax. Dorsal thorax ground color. Pronotum ground color, piceous within paramedian fissure, connected across midline by V-shaped castaneous mark in some paratypes, all but middle of lateral fissure, ambient fissure castaneous, castaneous mark on disc from posterior lateral fissure angled towards posterior paramedian fissure, connecting fissures in some paratypes, curved castaneous mark on lateral portion of lateral disc, covered with short golden pile and radiating long piceous pile. Pronotal collar ground color with short golden pile, radiating long piceous pile. Mesonotum greenish-tawny, castaneous marks outlining submedian sigillae, expanding in posterior of submedian sigilla, J-shaped castaneous mark surrounding lateral and posterior lateral sigillae not reaching anterior medially, lateral portion of J-shaped mark not reaching anterior margin in some paratypes, J-shaped castaneous mark on either side of midline anterior to anterior arms of cruciform elevation including scutal depressions laterally and fusing medially, extending anteriorly along midline terminating between posterior submedian sigillae, posterior margin of mesonotum castaneous, transverse castaneous fascia on either side of midline on posterior cruciform elevation, fused in some paratypes. Metanotum ground color with castaneous posterior margin, castaneous absent in some paratypes. Short golden pile on mesothorax and metathorax, long silvery pile between anterior arms of cruciform elevation, posterior to anterior arms of cruciform elevation, on lateral mesothorax, posterior mesothorax, radiating from posterior wing groove, and on posterior metanotum, long piceous pile radiating from mesothorax. Ventral thoracic segments ground color covered with short silvery pile, radiating long silvery pile.

Wings. Fore wings and hind wings hyaline, with eight and six apical cells respectively. Venation castaneous proximally, ground color in some paratypes, becoming darker distally, except castaneous costal margin and radius & subcostal vein past node, piceous proximal and castaneous distal anal vein 2 + 3, pterostigma present. Paired linear infuscation in apical cells. Wing margin infuscated, marginal area with linear infuscations appearing to extend from apical cells. Basal membrane grayish. Hind wing venation castaneous becoming darker distally except ground color median vein and anal vein 1. Anal vein 3 about half the length of anal vein 2 with curved distal terminus. Anal cell 3 and plaga gray proximally, anal cell 2 along anal veins 2 and anal vein 3 to curve, anal cell 1 along anal vein 2 margined with gray, gray margined with infuscation. Wing margin infuscated.

Legs. Ground color except castaneous striped femora and light castaneous distal pretarsi, and distal pretarsal claws, long silvery pile radiating from legs. Fore femora with proximal spine longest with slightly curved tip, forming an acute angle to femoral axis, secondary spine angled slightly more than primary spine, tertiary spine more erect than secondary spine, secondary and tertiary spines about the same length with curved tip, very small apical spine emerging from distal base of tertiary spine with smallest acute angle to femoral axis. Spines ground color with castaneous tip. Tibial spurs and comb castaneous. Meracanthus broadly triangular, ochraceous with castaneous mark on medial base, reaching anterior of medial opercular margin. Female meracanthus shape and color similar to male, extending beyond posterior opercular margin.

Opercula. Male operculum greenish-ochraceous, covered with short silvery pile and radiating long silvery pile, angled mediad, lateral base bent dorsally on lateral body, lateral margin straight, curved posterolateral margin forming obtuse angle to straight posterior margin, with finger-like posteromedial extension, semicircular medial margin, not meeting medially reaching to medial meracanthus, not covering tympanum, only medial region reaching to anterior of lateral sternite II. Female operculum similarly colored, laterally of similar shape but transverse posterior margin terminating in a pointed medial margin reaching only to middle of meracanthus, reaching to anterior of sternite II.

Abdomen. Abdominal tergites ground color laterally with castaneous dorsum and piceous posterior margin, amount of castaneous increasing in posterior tergites, tergites covered with short silvery pile, long silvery pile surrounding timbal cavity, long golden pile radiating from castaneous auditory capsule, lateral tergites 6–7 and all of tergite 8. Timbal exposed, white marked with ten long ribs and nine intercalary ribs, ribs castaneous, darker dorsally. Male sternites 1–3 ground color, sternites 4–7 castaneous becoming darker in posterior sternites, castaneous reduced in some paratypes, sternite VIII ground color with castaneous anteromedial region, radiating silvery pile, very dense on midline of tergite II, epipleurites castaneous except ground color anterior of epipleurite 3, castaneous becoming darker in posterior epipleurites, covered with silvery pile and radiating long golden pile. Female tergites and sternites similarly colored to male. Female sternite VII with deep, wide U-shaped medial notch, posterior notch extending as a point beyond arching posterolateral margin. Female abdominal segment 9 castaneous with lighter ventral margin, covered with short silvery pile and radiating long golden pile.

MEASUREMENTS (MM). N = 10 males or three females, mean (range). Length of body: males 20.03 (19.25– 21.20), females 19.95 (19.45–20.40); length of fore wing: males 24.49 (23.10–25.95), females 23.85 (23.45–24.45); width of fore wing: males 8.75 (8.35–9.20), females 8.25 (7.90–8.85); length of head: males 3.66 (3.35–3.85), females 3.43 (3.35–3.50); width of head including eyes: males 6.51 (6.30–6.70), females 6.17 (6.00–6.40); width of pronotum including suprahumeral plates: males 7.47 (7.20–7.90), females 7.02 (6.75–7.40); width of mesonotum: males 6.15 (5.90–6.40), females 5.97 (5.60–6.30).

DIAGNOSIS. Although the majority of Herrera species have prothoracic and mesothoracic markings, only H. castanetorquata n. sp., H. nigrotorquata Sanborn 2018b , H. tigrina ( Boulard, 1986a) , and H. viriventralis n. sp. possess a transverse fascia in the entire pronotum ambient fissure. The new species can be distinguished from H. nigrotorquata by the C-shaped marks on either side of the pronotal midline connecting the posteromedial paramedian and lateral fissures, the lack of markings on the lateral sigillae posterior margin, the female operculum reaches the meracanthus point, the narrow anterior opening of the V-shaped notch in female sternite VII, and the contrasting ventral abdomen coloration in that species. Herrera tigrina has a transverse posterior opercular margin with a thin medial extension, the wide anterior opening of the female sternite VII notch, and the small basal pygofer lobe appendage distinguish it from this new species. Herrera castanetorquata n. sp. can be distinguished from by H. viriventralis n. sp. by the markings on the frons, around the lateral ocelli, in the posterior pronotal lateral fissure, surrounding the mesonotal submedian sigillae, the transverse mark on the posterior abdominal tergites, the posterior margin to the timbal cavity being angled anteriorly rather than being transverse, the ventral abdomen is the same color as the dorsal abdomen, and the basal pygofer lobe appendage terminates in two points in this new species. The mark in the ambient fissure of H. signifera Sanborn, 2019b does not extend across the dorsal midline.

DISTRIBUTION. The species is known from the type series collected in Brazil and Peru.
