Paratypes. “ TRINIDAD: Reunion Agr./ Station, Cocoa Research / 20–23-March-2000 R.E./Woodruff. blacklight trap ” one male (FSCA), two males (AFSC); “ TRINIDAD: Blanchisseuse/Ward, Morne Bleu/(11 mi.

Etymology. The name is a combination of hyperoche (Gr. hyperoche, projection, prominence), and - labrys (Gr. labrys, two-bitted ax) in reference to the axe-like shape of the upper pygofer lobes characteristic of this new species.
Remarks. A small piceous and red species easily distinguished by the five hind wing apical cells, the inflated abdomen with dorsal ridge, the shape of the pygofer, particularly the elongated, flattened, posteriorly oriented upper pygofer lobes with the distal end expanding into an axe-like shape.
Description. Ground color of head and thorax castaneous tawny marked with piceous, abdomen ferruginous marked with piceous.
Head. Head wider than mesonotum, ground color with transverse piceous fascia including ocelli, expanding along median eye to posterolateral of median angle of eye, posterior extensions medial to lateral ocelli curving laterad posterior to lateral ocelli, fascia incomplete in some paratypes, short golden pile on dorsum, denser in some paratypes, longer silvery pile posterior to eye. Ocelli rosaceous, eyes castaneous. Ventral head ground color with piceous spot on posteromedial lorum and gena, with short silvery pile and long white pile, long pile very dense on posterior lorum in some paratypes. Postclypeus bulbous with nine transverse grooves, ground color with longitudinal piceous fascia on midline expanding laterally into medial transverse grooves on ventral surface, green ovoid spot on apex, piceous within transverse grooves on dorsal surface forming angled fascia on either side of midline, medial dorsal surface ground color, short silvery pile on lateral margin and within transverse grooves, radiating long silvery pile.Anteclypeus piceous covered with long silvery pile. Rostrum ground color with piceous tip, long silvery pile on tip, reaching to middle trochanters. Scape, pedicel, and first flagellar segment piceous, remaining antennal segments castaneous.
Thorax. Dorsal thorax ground color. Prothorax with piceous fascia on either side of midline expanding anterolaterally into triangular mark on disk anterior to paramedian fissure and curving posterolaterally anterior to ambient fissure connecting to piceous fascia in lateral fissure, piceous mark on anterior disk between paramedian and lateral fissures and lateral to lateral fissure, lateral mark extending posterolaterally across anterior and central disk in some paratypes, covered with short silvery pile, pronotal collar ground color with short silvery pile on lateral angle. Mesonotum ground color, piceous submeidan sigillae, lateral sigillae piceous in posterior half with anterior extension along lateral margin not reaching anterior margin, piceous fascia from scutal depressions across distal anterior arms of cruciform elevation to posterior mesonotum and posteromedial wing groove. Metanotum piceous with ground color posterior margin with piceous lateral mark. Silvery pile on mesonotum on disk, denser and longer laterally, between anterior arms of cruciform elevation, in wing groove, and on posterior metanotum. Ventral thoracic segments ground color, piceous mark on posterolateral episternum 3, covered with short and long silvery pile.
Wings. Fore wings and hind wings hyaline with eight and five apical cells respectively. Costal margin ochraceous at base, green in some paratypes, becoming castaneous distally, remaining venation ferruginous becoming piceous distally except piceous anal vein 2 + 3. Basal cell hyaline. Pterostigma absent. Basal membrane of fore wing gray with darker posterior margin. Venation of hind wing similarly colored, anal vein 3 with curved terminus, about half as long as anal vein 2. Anal cell 3 margined with grayish, anal cell 2 along anal vein 3 grayish, gray margined with infuscation, infuscation expanding into central anal cell 2.
Legs. Legs ground color except green middle and hind tibiae, piceous spot on distomedial coxae, femora striped with dark castaneous, distal tibiae, distal tarsi and distal tarsal claws piceous. Fore femora with four angled spines, spines become smaller and less erect distally, primary spine straight, secondary, tertiary and apical spines curved, spine castaneous with piceous base. Tibial spurs and tibial combs castaneous. Meracanthus ground color, greenish in some paratypes, with piceous spot on anteromedial base, triangular, extending less than half the length of male sternite I.
Opercula. Male operculum with short, straight lateral margin to small, rectangular, lateral extension, lateral and posterior margins curved to rounded medial end, angled posteromediad reaching medial meracanthus, covering central tympanal cavity, not reaching sternite II, ground color, greenish in some paratypes, covered with silvery pile, with long silvery pile radiating from edge.
Abdomen. Abdominal tergites ferruginous with green posterior margin. Tergite 1 with piceous lateral mark along timbal cavity, tergite 2 with piceous anterior except on midline, tergites 3–8 with piceous anterior midline, piceous spot laterally on tergites 5–7 increasing in size in posterior tergites, sternite 8 piceous anteriorly, ground color posteriorly and laterally. Timbal exposed, white with castaneous ribs, nine long ribs and eight intercalary ribs. Male sternite I dark castaneous with ground color posterior, sternite II ground color anteromedially, dark castaneous medially piceous laterally, completely piceous in some paratypes, sternites III–VI ferruginous anteriorly with green posterior, green very obvious in some paratypes, sternite VII with ferruginous anterior and dark castaneous posterior, sternites with short silvery pile and radiating long silvery pile, sternite VII with transverse posterior margin, sternite VIII ground color, elongated with V-shaped notch when viewed from the posterior, covered with short silvery pile, radiating long piceous pile. Epipleurites similarly colored to sternites.
Genitalia. Male pygofer ferruginous, piceous spots on anterolateral surfaces and on posterior midline including dorsal beak, ventral margin and upper pygofer lobes green, dorsal beak shorter than piceous anal styles. Distal shoulder short, extending to base of anal styles, forming a small posteriorly oriented triangular extension. Pygofer basal lobe thin, about as wide as pygofer margin, adpressed to pygofer, reaching to base of upper pygofer lobe, angled laterad at base. Upper pygofer lobes elongated, flattened, curving posteriorly with terminus expanding into ax-like shape end curving mediad but not crossing midline. Claspers, small, thin, angled mediad with hooked terminus, radiating short silvery pile. Aedeagus tubular with extended pseudoparamere and endotheca, castaneous with ochraceous terminal membrane.
Measurements (mm). N = six males, mean (range). Length of body: 12.92 (12.25–13.55); length of fore wing: 14.40 (13.80–14.90); width of fore wing: 5.58 (5.30–5.75); length of head: 2.47 (2.40–2.55); width of head including eyes: 4.28 (4.15–4.45); width of pronotum including suprahumeral plates: 4.42 (4.30–4.60); width of mesonotum: 3.78 (3.70–3.90).
Diagnosis. The axe-like extension of the upper pygofer lobe distinguishes Calyria hyperochelabrys n. sp. from all other species of Calyria. In addition, the new species can be distinguished quickly from C. jacobii Bergroth, 1914, C minutopercula Sanborn, 2020a, and C. telifera (Walker, 1858a), and C. chaetoacontia Sanborn 2020d by the very small opercula in these species. Similarly, the new species can be distinguished from C. cuna (Walker, 1850), C minutopercula Sanborn, 2020a, C. mogannoides Jacobi, 1907, and C. telifera (Walker, 1858a), C. chaetoacontia Sanborn 2020d, and C. xiphion Sanborn 2020d by the spot of infuscation on the fore wing apex in these species. It can be distinguished from C. fenestrata (Fabricius, 1803) by the ferruginous coloration, larger body size (> 14 mm), and abdomen widening to segment four in C. fenestrata. Calyria uncinata Sanborn, 2020c can be distinguished by the dark castaneous body coloration marked with copious piceous, the ferruginous fascia on the posterior abdominal tergites, and the large claw-like terminus of the upper pygofer lobe. Finally, C. stigma (Walker, 1850) is the most similar in general appearance but can be distinguished by the anterior extension of the postclypeus being transverse and less than the length of the postclypeus covered by the supra-antennal plate, the larger male opercula that almost cover the tympanal cavity, claspers that are bent at an approximate right angle while tapering distally, and the tapering, sinusoidal upper pygofer lobe in that species.
Distribution. The new species is known only from the type series collected in several localities in northern Trinidad.
