Herrera cephalodigramma n. sp.

( Fig. 17 )

TYPE MATERIAL. Holotype. “ PERU: Dept. Cusco / Kosñipata Vy., San Pedro / 16–19-XI-2009, / J. Heppner, C. Carrera, / E. Huamani, 1368m ” male ( FSCA) . Paratype. “ PERU: Dpto. Amazonas / 43 rd.km. NE Chiriaco / el. 1050ft. 3–5- XI- / 1978 L.J. Barkley ”, one male ( LSAM) .

ETYMOLOGY. The name is a combination of cephal- (Gr. kephale, head), -di- (Gr. di-, two, double) and -gramma (Gr. gramma, letter, mark) in reference to the two marks on the dorsal head of this species.

REMARKS. This is a small species with piceous markings on the head and thorax and a piceous fascia on the abdominal sternites.

DESCRIPTION. Ground color greenish-tawny marked with piceous. The coloration is probably green in fresh specimens as the paratype is greener than the holotype. Markings in paratype reduced compared to holotype.

Head. Head wider than mesonotum, ground color with laterally curving piceous mark from medial lateral ocellus extending anteriorly on vertex and frons along epicranial suture anterior arm not reaching frontoclypeal suture. Ocelli rosaceous, eyes castaneous. Dorsal head radiating dense, long piceous pile, long silvery pile posterior to eye. Ventral head ground color, castaneous fascia on anteromedial lorum and castaneous spot on medial lorum at junction with posterior postclypeus, marks absent in paratype. Postclypeus ground color with piceous fascia on either side of midline extending the length of the transverse ridges, fascia reduced to castaneous mark on dorsal postclypeus in paratype, centrally sulcate from anterior to posteroventral margin to apex, with eleven transverse ridges, short silvery pile on lateral margin, radiating long piceous pile. Anteclypeus ground color with piceous fascia on posterior half of carina and piceous posterior margin, marks absent in paratype. Ventral head and anteclypeus with short silvery, long white pile and radiating piceous pile. Mentum ground color, labium tawny, greenish in paratype, with castaneous lateral fascia and piceous tip, reaching to hind coxae. Proximal scape ground color, remaining antennal segments castaneous.

Thorax. Dorsal thorax ground color, piceous fascia in paramedian fissure splitting to form ovoid ground color mark in posterior half fissure, piceous fascia in posterior half of lateral fissure extending to ambient fissure, small transverse piceous fascia on ambient fissure midline, pronotal collar ground color. Mesonotum with piceous mark along medial, posterior and posterolateral submedian sigilla, not reaching anterior medial margin, J-shaped mark outlining lateral and posterior lateral sigilla, hemispherical piceous spot anterior to anterior arms of cruciform elevation including scutal depression laterally, not meeting medially, transverse piceous fascia on posterior mesonotum, metanotum ground color, light castaneous mark on lateral margin in paratype. 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, long piceous pile radiating from anepisternum 2.

Wings. Fore wings and hind wings hyaline, with eight and six apical cells respectively. Venation ground color at base, becoming piceous distally, except costal margin reddish to node and 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 gray with darker posterior margin. Hind wing venation ground color proximally becoming piceous distally, wing margin infuscated. Anal vein 3 with piceous spot on base, about one-third the length of anal vein 2, with a slightly 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 fore femora spines, piceous distal tibiae, greater proportion in middle and hind tibiae, distal pretarsus, and tips of pretarsal claws, short and long silvery pile radiating from legs. Fore femora spines parallel, with proximal spine longest, straight, secondary intermediate in length with curved terminus, tertiary spine shorter than secondary spine with curved terminus, and very small apical spine emerging from distal base of tertiary spine. Tibial spurs and comb castaneous. Meracanthus broadly triangular, ground color, reaching anterior of sternite II.

Opercula. Male operculum ground color with castaneous lateral margin, inflated at base, smoothly curving from base to above abdominal sternites when viewed from the side, lateral margin straight, angled slightly mediad, curved posterior and medial margins, roughly hemispherical posteromedially, not meeting medially, reaching lateral trochanters, tympanum concealed, reaching to middle of sternite III, long silvery pile radiating from margin.

Abdomen. Abdominal tergites tawny-castaneous in holotype, greenish-tawny in paratype, 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 tergite 7 and all of tergite 8. Timbal exposed, white marked with eight long and seven intercalary castaneous ribs. Male sternite I ground color, sternites II–VIII ochraceous laterally, piceous medially forming a piceous fascia along ventral midline, castaneous pile radiating from central sternites I and II and all of sternite VIII, sternite VIII V-shaped when viewed from the posterior. Epipleurites ochraceous medially, tawny-castaneous laterally.

Genitalia. Male pygofer colored like tergites, with lighter ventral margin, basal pygofer lobes and upper pygofer lobes ochraceous, and castaneous dorsal beak. Dorsal beak narrow, longer than piceous anal styles. Pygofer basal lobe about half-length of pygofer, roughly C-shaped, expanding posteriorly at junction with basal pygofer lobe appendage, radiating golden pile, very dense at apex. Upper pygofer lobes very small, flattened with rounded terminus, bent posteriorly from base. Claspers small, smoothly curved posteriorly to support aedeagus, anterior hidden by dense pile and basal lobe appendage. Basal lobe appendage castaneous, flattened and curved posteriorly at base, meeting along midline, narrowing and bifurcating in one large lateral curved extension and another with four spine-like processes. Aedeagus tubular, dark castaneous.

Female is unknown.

MEASUREMENTS (MM). N = two males, mean (range). Length of body: 13.05 (13.00–13.10); length of fore wing: 16.98 (16.75–17.20); width of fore wing: 5.90 (5.75–6.05); length of head: 2.75 (2.75–2.75); width of head including eyes: 5.05 (5.00–5.10); width of pronotum including suprahumeral plates: 6.53 (6.25–6.80); width of mesonotum: 4.90 (4.85–4.95).

DIAGNOSIS. Herrera cephalodigramma n. sp. is one of a number of species of Herrera that possess prothoracic and mesothoracic markings. It can be distinguished by the two angled piceous marks on the head. In contrast, H. lugubrina compostelensis Davis, 1938 , H. humilistrata Sanborn & Heath, 2014 , and H. signifera Sanborn, 2019b have a primarily piceous head, the ocelli are margined with piceous in H. chanchamayoensis n. sp., H. freiae Sanborn, 2019b , H. guianaensis ( Sanborn 2011a) , H. polygramma n. sp., H. quinimaculata ( Sanborn, 2011a) , and H. sigillata Sanborn, 2018b . Finally, H. moyabambaensis n. sp. lacks any head marking and the parallel stripes on the ventral postclypeus found in this new species.

DISTRIBUTION. The species is known from the type series collected in the Departments of Cusco and Amazonas, Peru.
