Herrera nigratorquata n. sp.

( Fig. 5 )

Type material. Holotype. “ PANAMA: Coclé, Rio Indio / Lodge, N El Valle, / 18 to 20–VIII–2012 575 m / J. Heppner 4” one female ( FSCA) .

Remarks. One of the three undetermined species listed by Wolda (1989) or Wolda & Ramos (1992) may represent this new species. However, no diagnostic characteristics were provided for any of these species, none were collected in the same Province where the holotype was collected ( Wolda 1989; Wolda & Ramos 1992), and I was unable to locate any specimens labeled as one of the undetermined of the species. As a result, I was unable to determine if the new species represents one of the previously mentioned species.

Etymology. The name is in reference to the piceous (L. niger, black) fascia in the posterior ambient fissure of the pronotum (L. torquatus, adorned with a necklace or collar).

Description. Ground color of head and thorax greenish testaceous marked with piceous and castaneous, abdomen marked with green and castaneous. Testaceous may be green in fresh specimens based on color variation specimens of H. ancilla over time.

Head. Head wider than mesonotum, greenish testaceous with piceous marks lateral to posterior epicranial suture encircling lateral ocellus with castaneous extension in anterior arm of epicranial suture, triangular piceous mark arising laterally to this mark on posterior head extending to medial margin of eye anterior to medial angle of eye, piceous posterior to eye forming an inverted testaceous triangle extending posteromedially from medial angle of eye, frons piceous except for castaneous midline, castaneous spot on lateral vertex on right side next to margin of eye at the level of the center of all ocelli. Covered with black pile, longer posterior to eye, shorter silvery pile posterior to eye. Ocelli rosaceous and ochraceous. Eyes golden. Ventral head light testaceous, lorum ochraceous. Postclypeus centrally sulcate, with nine transverse grooves, testaceous, darker dorsally, light castaneous in transverse grooves 1–3 on dorsal surface, incomplete longitudinal castaneous mark on either side of central sulcus with lateral extension towards transverse grooves 4–7, silvery pile on lateral margin. Anteclypeus castaneous except for greenish anterior margin and anterior half of carina connecting to form a triangular mark on either side of anterior midline. Long piceous and short silvery pile on ventral head and anteclypeus. Mentum greenish, labium greenish anteromedially, piceous laterally and at tip, reaching to anterior of hind coxae. Antennae fuscous except proximal scape, distal annular mark on scape and proximal annular mark on pedicel.

Thorax. Dorsal thorax greenish testaceous. Pronotum with piceous mark in posterior median fissure extending laterally from medial end of fissure across disk forming a V-shape, transverse piceous mark in posterior ambient fissure extending onto anterior of pronotal collar, wider on midline, light castaneous marks on dorsal midline connecting from apex of piceous V-shaped marks forming an open V-shape, small castaneous spot anterior to medial piceous V-shaped mark, small linear castaneous marks on lateral disk. Pronotal collar greenish testaceous except for transverse piceous fascia and piceous mark on anterior margin of pronotal collar lateral angle, lateral margin of pronotal collar adpressed. Mesonotum greenish testaceous with curved castaneous mark from anterior midline along medial margin of submedian sigilla expanding in posterior submedian sigilla, mark on midline of disk expanding laterally posterior to scutal depression to anterior arm of cruciform elevation, posterior margin posterior to anterior arm of cruciform elevation piceous edged in castaneous, proximal portion of posterior arms of cruciform elevation with light castaneous mark. Metanotum greenish with castaneous marks on posterior margin. Long piceous pile on dorsum of thorax, short golden pile between anterior arms of cruciform elevation and posterior to anterior arms of cruciform elevation, long golden pile on posterior mesothoracic margin, radiating from posterior wing groove, and on metanotum. Ventral thoracic segments ochraceous except greenish testaceous anepisternum 2, with long and short silvery pile.

Wings. Tegmina and wings hyaline, milky tinge on proximal two thirds of fore wing and over the middle of the posterior hind wing when viewed from an angle. Venation greenish testaceous, becoming castaneous and finally piceous distally, except castaneous costal margin to node and piceous proximal half of anal vein 2 + 3, castaneous spot on proximal cubitus anterior along basal cell, pterostigma present. Basal membrane grayish. Hind wing venation castaneous except green proximal cubitus anterior vein. Vanal fold castaneous, medioproximal anal cell 2, anal cell 3 and anal cell 2 along anal veins 2 and 3 gray.

Legs. Coxae and trochanters ochraceous, femora and tibiae greenish, fore femora striped with castaneous, fore tibiae castaneous distally, middle tibiae with castaneous distal annulus. Fore femora with proximal spine most oblique, secondary spine and tertiary spine angled less than primary spine, tertiary spine curved more than secondary spine, and small apical spine emerging from base of tertiary spine. Spines castaneous with darker anterior margin and tip, primary spine largest, secondary intermediate in size, tertiary spine larger than secondary spine, apical spine smallest. Tibial spurs and comb castaneous with piceous tips. Tarsi dark castaneous except green proximal mesotarus, pretarsal claws greenish proximally with piceous tips.

Operculum. Female operculum ochraceous with straight lateral margin angled toward midline, rounded posterolateral margin forming an obtuse angle to straight posterior margin, medial margin acutely angled with rounded terminus reaching medially to middle meracanthus not covering tympanal cavity, covered with long silvery pile. Female meracanthus broadly triangular, pointed, extending beyond posterior margin of operculum, ochraceous with radiating long silvery pile.

Abdomen. Tergites testaceous with green hind margins, tergites 8 and 9 castaneous instead of testaceous, castaneous dorsal half of auditory capsule, castaneous spot on lateral tergite 7, tergites covered with piceous pile, more dense on posterolateral surfaces, golden pile on lateral tergites. Female abdominal segment 9 castaneous dorsally, testaceous fasciae on dorsolateral surface, ochraceous ventrolaterally, caudal beak castaneous with piceous margin and ochraceous spots on lateral base, with piceous pile dorsally and radiating long golden pile ventrally and laterally. Posterior margin of abdominal segment 9 sinuate, ochraceous. Sternites ochraceous with transverse light castaneous marks near anterior margin of sternites III–VII with additional mark near posterior of sternite VI, mark on sternite IV extending posteriorly, mark on sternite VII surrounds base of notch. Female sternite VII with sinuate posterior margin extending to tergite 7 before curving anteriorly to terminus, deep medial notch almost reaching anterior of sternite VII, semicircular medially, straight margin angled laterally to almost middle of sternite length where angle decreases to posterior margin. Sternites covered with short and radiating long silvery pile, very dense on medial sternite II.

Genitalia. Female gonapophyses VIII and IX castaneous with piceous tip and lateral testaceous fascia not reaching tip, gonapophysis X castaneous with lateral piceous fascia extending beyond dorsal beak with radiating golden pile. Gonocoxite IX ochraceous. Anal styles ochraceous with castaneous spots proximally and fuscous marks distally.

Male is unknown.

Measurements (mm). N = 1 female. Length of body: 18.9; length of fore wing: 21.2; width of fore wing: 8.3; length of head: 3.1; width of head including eyes: 6.1; width of pronotum including suprahumeral plates: 6.5; width of mesonotum: 5.7.

Diagnosis. Herrera nigratorquata n. sp. can be distinguished from H. infuscata Sanborn, 2009 by the lack of infuscation in the distal fore wing. The lack of piceous on the head and the non-contrasting abdomen distinguishes this new species from H. ancilla ( Stål, 1864) , H. coyamensis Sanborn, 2007a , and H. umbraphila Sanborn & Heath, 2014 . The bodies of H. humilistrata Sanborn & Heath, 2014 , H. laticapitata Davis, 1938 , H. lugubrina compostelensis Davis, 1938 , and H. lugubrina lugubrina ( Stål, 1864) , are piceous or the mesothorax is marked with piceous. Herrera sigillata n. sp. can be distinguished easily by the lack of a piceous transverse fascia on the pronotum or mesothoracic markings, the short operculum curving to a short point medially, the longitudinal fascia on the abdominal sternites, and the lateral posterior sternite VII curving anteriorly to the epipleurite.

Distribution. The species is known only from the holotype collected in Coclé Province, Panama.
