ETYMOLOGY. The name is a combination of viri - (L., vireo, to be green) and - ventralis (L., ventralis , of the belly) in reference to the green ventral surface of the body.

REMARKS. This is a light castaneous species with a green ventral surface. The contrasting green ventrum distinguishes it from all other Herrera species.

DESCRIPTION. Ground color of head and thorax dorsal side light castaneous marked with green, dark castaneous and piceous, dorsal abdomen castaneous, ventrum green.

Head. Head slightly wider than mesonotum, ground color with lighter supra-antennal plate and anterolateral vertex, posterior median ocellus and medial and anterior lateral ocelli surrounded by darker castaneous, piceous posterior to eye extending medially to posterolateral vertex. Ocelli rosaceous, ochraceous in some paratypes, eyes dark castaneous. Head with short silvery pile, longer silvery pile posterior to eye, dorsum radiating long piceous pile. Ventral head green with short silvery pile, long piceous pile radiating from lorum and gena, dense long white pile on lorum and lateral gena. Postclypeus light castaneous dorsally, green ventrally with dark castaneous mark extending from ventral sulcus bifurcating and expanding on either side of sulcus with transverse terminus at apex, centrally sulcate from anterior to posteroventral margin to around apex, with ten transverse ridges, short silvery pile on lateral margin, radiating long piceous pile, denser on dorsal surface. Anteclypeus green with piceous carina and posterolateral area, piceous reduced or castaneous in some paratypes, anteclypeus with short silvery pile, long white pile and radiating sparse, long piceous pile. Mentum green, labium castaneous midline, piceous laterally and at tip, reaching to anterior margin of hind coxae. Antennal segments castaneous with lighter annular mark on distal scape and proximal pedicel.

Thorax. Dorsal thorax ground color. Pronotum with green anterior margin and greenish along midline, reduced in some paratypes, piceous mark in posterior paramedian fissure extending anteriorly onto disk and rejoining forming elongated ground color spot on posterior or mark, extending as castaneous mark to meet on midline with mark from contralateral side, not meeting in some paratypes, one paratype with castaneous spot on midline instead of fascia, piceous in ambient fissure except on posterior midline, reduced medially in one paratype, lateral ambient fissure castaneous, radiating long piceous pile. Pronotal collar ground color, greening anteriorly in holotype and one paratype, radiating long piceous pile. Mesonotum ground color, laterally and cruciform elevation green, J-shaped dark castaneous mark along medial and posterior submedian sigilla, castaneous mark on either side of midline anterior to anterior arms of cruciform elevation including scutal depressions laterally, meeting anteromedially in holotype, separate in paratypes, posterior mesonotum castaneous, wing groove green. Metanotum ground color. Short silvery pile between anterior arms of cruciform elevation, long silvery pile on lateral mesonotum, posterior mesothorax, posterior to anterior arms of cruciform elevation, radiating from posterior wing groove, and on posterior metanotum. Long piceous pile radiating from mesothorax. Ventral thoracic segments green with short silvery pile, radiating long white pile.

Wings. Fore wings and hind wings hyaline, with eight and six apical cells respectively. Venation ground color, becoming piceous distally, except piceous proximal anal vein 2 + 3, pterostigma present. Very light, paired linear infuscation in apical cells and on wing margin. Basal membrane grayish margined with piceous posteriorly. Hind wing venation ground color becoming piceous distally, except dark castaneous proximal anal vein 3. Anal vein 3 curved distally. Proximal anal cell 3 and plaga gray, anal cell 2 along anal veins 2 and 3, anal cell 1 along anal vein 2 margined with gray. Wing margin lightly infuscated.

Legs. Ground green except castaneous fasciae on dorsal fore femora, piceous distal tibiae, less in middle and least in hind tibiae, fore and middle tarsi and metatarsus, mesotarsus and distal hind pretarusus, fore leg pretarsal claws, and distal pretarsal claws of middle and hind legs, fore femora with patch of piceous pile distally, long silvery pile radiating from legs. Fore femora with proximal spine longest and most oblique, secondary and tertiary spines slightly angled with curved tip, parallel, about the same length, and very small apical spine emerging from distal base of tertiary spine. Spines dark castaneous at base with lighter area distally except completely piceous apical spine, base of spines connected by dark castaneous fascia. Tibial spurs and comb castaneous. Meracanthus broadly triangular with curved lateral margin, green, not reaching anterior margin of medial operculum.

Opercula. Male operculum green covered with short and radiating long silvery pile, lateral margin straight, angled slightly medially, curved posterolateral margin and sinuate posterior margin, rounded medial margin, and curved anteromedial margin forming thin, finger-like medial extension to operculum, opercula not meeting medially reaching to middle hind coxae, not covering tympanum nor reaching to anterior of lateral sternite II, sinuous when viewed from the posterior.

Abdomen. Abdominal tergites castaneous with green posterolaterally, lighter membranes between tergites, tergites covered with golden and piceous pile, long golden pile surrounding timbal cavity and radiating from dark castaneous auditory capsule. Timbal exposed, white with eight long ribs and seven intercalary ribs. Male sternites green, transverse castaneous spot on posterior midline of sternite II in holotype, absent in all paratypes, sternite VII and VIII ochraceous but appears to be faded from green, sternite VIII with darker posterior margin, smoothly curved when viewed from posterior and radiating piceous pile, sternites covered with short silvery and long pile radiating from sternites, epipleurites green, ochraceous in one paratype, with silvery pile.

Genitalia. Male pygofer castaneous with ochraceous lateral regions and piceous dorsal beak, basal lobes and upper pygofer lobes ochraceous. Dorsal beak narrow, slightly longer than castaneous margined with piceous anal styles. Pygofer basal lobe about half-length of pygofer, angled mediad with medially rounded apex radiating dense golden pile. Upper pygofer lobes short, knob-like angled mediad, distal shoulder recurved mediad radiating long castaneous pile. Claspers wide at base with short, rounded medial terminus radiating long castaneous pile. Basal lobe appendage flattened, not crossing across midline, curved distally with a pointed tip. Aedeagus tubular, castaneous.

MEASUREMENTS (MM). N = five males, mean (range). Length of body: 17.34 (16.05–17.95); length of fore wing: 22.09 (19.40–23.35); width of fore wing: 8.30 (7.50–8.60); length of head: 3.29 (3.05–3.45); width of head including eyes: 6.21 (5.95–6.65); width of pronotum including suprahumeral plates: 7.27 (6.95–7.55); width of mesonotum: 5.90 (5.55–6.20).

DIAGNOSIS. Although the majority of Herrera species have prothoracic and mesothoracic markings, only H. castanetorquata n. sp., H. nigrotorquata , H. tigrina , 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 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 that new species. The mark in the ambient fissure of H. signifera does not extend across the dorsal midline.

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