Herrera dentata n. sp.

( Fig. 19 )

TYPE MATERIAL. Holotype. “ PERU: San Martin Dept. / Moyabamba, vic. / Ecológico “Rumipata” / 11–13-X-2012 J. E. Eger // S 06º 04’32.0”, W / 076º 58’ 07.5” 970 / m, MV & UV Light ” male ( FSCA). Paratypes. Same data as holotype, one male ( AFSC).

ETYMOLOGY. The name is in reference to the tooth-like basal pygofer lobe appendage (L. dentatus, toothed, pointed) in this species.

REMARKS. This is another monochromatic species but smaller than H. concolor .

DESCRIPTION. Ground color ochraceous, castaneous markings on male sternites VII and VIII. The coloration is probably green in fresh specimens as the paratype has greenish areas on the body and wings.

Head. Head wider than mesonotum, ground color. Ocelli rosaceous, eyes castaneous. Dorsal head radiating dense, long piceous pile, long silvery pile posterior to eye. Ventral head ground color. Postclypeus ground color, centrally sulcate from anterior to posteroventral margin to apex, with nine transverse ridges, short silvery pile on lateral margin, radiating long piceous pile. Anteclypeus ground color. Ventral head and lateral anteclypeus with short silvery and radiating long silvery pile. Mentum ground color, labium ground color with piceous tip, reaching to hind coxae. Proximal scape and proximal pedicel ground color, remaining antennal segments castaneous.

Thorax. Dorsal thorax ground color, unmarked, with sparse, short golden pile, radiating long piceous pile, long golden pile between anterior arms of cruciform elevation, posterior to anterior arms of cruciform elevation, on lateral and posterior mesothorax, radiating from posterior wing groove, and on posterior metanotum. Ventral thoracic segments ground color with long and short silvery pile.

Wings. Fore wings and hind wings hyaline, with eight and six apical cells respectively. Venation greenish at base, very green in paratype including costal margin and radius & subcostal vein to node, becoming castaneous distally, except 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 along with additional marks. Basal membrane greenish-gray. Hind wing venation greenish proximally becoming castaneous distally. Anal vein 3, about half the length of anal vein 2, with a curved terminus. Proximal anal cell 3 and plaga gray, anal cell 2 along anal vein 3 margined with gray, gray margined with infuscation distally.

Legs. Ground color except castaneous tips of fore femora spines, castaneous distal pretarsus, and piceous tips of pretarsal claws, short and long silvery pile radiating from legs. Fore femora with proximal spine longest, forming an acute angle, secondary spine more erect than primary spine, about as long as tertiary spine that is intermediate in its angle to the femoral axis, and very small apical spine emerging from distal base of tertiary spine. Tibial spurs and comb with castaneous tips. Meracanthus broadly triangular, ground color, reaching anterior of medial opercular margin.

Opercula. Male operculum ground color covered with long silvery pile, lateral margin extended laterally at base, curved mediad posterior to lateral extension, bent dorsally on lateral body, straight posterior margin, roughly rectangular with finger-like posteromedial extension, rounded medial margin that is bent dorsally, not meeting medially, reaching medial meracanthus, not covering tympanum, reaching to anterior of lateral sternite II, sinuous with right angle laterally when viewed from the posterior.

Abdomen. Abdominal tergites ground color with lighter posterior margin, tergites covered with short golden pile, golden pile surrounding timbal cavity and radiating from auditory capsule, long golden pile radiating from lateral tergites 6–7 and all of tergite 8. Timbal exposed, white marked with castaneous, three ribs visible. Male sternites ground color except sternite VII that is castaneous except for posterior of sternite and sternite VIII that is castaneous anterolaterally, radiating silvery pile, denser on midline of tergite II, sternite VIII radiating castaneous pile. Epipleurites ground color, with silvery pile.

Genitalia. Male pygofer ground color except ochraceous upper pygofer lobes ochraceous and castaneous dorsal beak. Dorsal beak narrow, longer than castaneous anal styles. Pygofer basal lobe about half-length of pygofer, curved mediad with medially rounded apex radiating dense golden pile. Upper pygofer lobes very small, knob-like, in lateral extension of pygofer, not reaching ventral pygofer margin. Claspers small, straight anterior margin angles anteromedially meeting on midline, smoothly curved posteriorly to support aedeagus not extending along uncus, uncus encircling anal tube, radiating long castaneous pile. Basal lobe appendage castaneous with piceous margin, tooth-like. Aedeagus tubular, dark castaneous, proximally, castaneous in middle, dark castaneous and narrowing distally, with undulating terminal membrane.

Female is unknown.

MEASUREMENTS (MM). N = two males, mean (range). Length of body: 16.10 (15.00–17.20); length of fore wing: 20.85 (19.80–21.90); width of fore wing: 7.53 (7.25–7.80); length of head: 2.98 (2.85–3.10); width of head including eyes: 5.43 (5.10–5.75); width of pronotum including suprahumeral plates: 6.20 (5.80–6.60); width of mesonotum: 5.28 (5.00–5.55).

DIAGNOSIS. Herrera dentata n. sp. can be distinguished from most species of the genus by its monochromatic coloration and lack of pronotal and/or mesothoracic markings. It can be distinguished from H. infuscata Sanborn, 2009 by the apical fore wing infuscation in that species. The relatively larger body size (greater than 15 mm vs. 14 mm or less), the green rather than tawny coloration and the dentate rather than curving basal pygofer lobe appendage distinguishes the new species from H. coyamensis Sanborn, 2007b . The larger body size (greater than 19 mm) and lack of long piceous pile distinguishes H. concolor from this new species. The lack of piceous pile, the wide opening to the timbal cavity, the leaf-like basal pygofer lobe appendage and the large opercula quickly distinguish H. phyllodes Sanborn, 2019b from the new species. Both H. lugubrina lugubrina ( Stål, 1864) and H. laticapitata Davis, 1938 are primarily piceous rather than green species. Herrera criqualicae ( Boulard, 1986a) is similar in that it is monochromatic with piceous pile but it can be distinguished by the larger body size (greater than 17.5 mm), the anterior head forms an oblique angle to the posterior head when viewed from the side rather than an almost right angle, the lateral operculum forms a right angle, and the upper pygofer lobes extend laterally in this species.

DISTRIBUTION. The species is known only from the type locality in Peru.
