( Fig. 23 )

TYPE MATERIAL. Holotype. “ PERU: San Martin Dept. / Moyabamba, vic. / Ecológico “ Rumipata ” / 13–18-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 female ( FSCA), two males ( AFSC) .

REMARKS. This is a larger Herrera species with two pairs of macular markings of the mesothorax and distinctive castaneous legs.

ETYMOLOGY. The name is a combination of quadri - (L. quadro, quartet) and - macula (L., macula, spot) in reference to the four spots on the mesothorax.

DESCRIPTION. Ground color greenish-tawny marked with piceous, legs and postclypeus castaneous. Fresh specimens are most likely green as the type series appears to be chemically altered.

Head. Head slightly wider than mesonotum, dorsal head ground color with piceous marks extending from anteromedial lateral ocelli to posterior margin posterior to lateral ocelli, long piceous pile radiating from dorsal head, long silvery pile posterior to eye, one paratype with short silvery pile on dorsal head. Ocelli rosaceous, ochraceous in some paratypes, eyes castaneous, ochraceous in one paratype. Ventral head ground color, castaneous in some paratypes, with piceous posterolateral lorum margin. Postclypeus castaneous, centrally sulcate with ten transverse ridges. Anteclypeus ground color with piceous mark on either side of posteromedial carina. Ventral head with short silvery pile, long piceous pile radiating from lorum, gena, and postclypeus, anteclypeus radiating long silvery and long piceous pile. Mentum ground color, labium ground color with piceous tip. Rostrum reaching to hind coxae. Scape and proximal pedicel light castaneous, remaining antennal segments dark castaneous, piceous in some paratypes.

Thorax. Dorsal thorax greenish-tawny unmarked except for piceous mark on medioposterior parapsidal sutures and in scutal depressions. Thoracic segments radiating long piceous pile, long silvery golden in wing groove, on lateral and posterior mesothorax, between anterior arms of cruciform elevation, laterally between anterior and posterior arms of cruciform elevation, and radiating from posterior margin of metanotum. Ventral thoracic segments ground color covered with short golden and radiating long golden pile.

Wings. Fore wing and wings hyaline with eight and six apical cells respectively. Venation ground color at base becoming darker distally except castaneous anterior costal margin and piceous on base and distal half of anal vein 2 + 3, reduced to piceous base in one paratype, pterostigma present, piceous spot on fore wing base, basal membrane of fore wing grayish. Hind wing venation ground color. Anal cell 3, anal cell 2 along anal vein 3 and along anal vein 2 to distal curve, and anal cell 1 along anal vein 2 to distal curve grayish, infuscation along gray in anal cell 2 and distal marginal area of hind wing.

Legs. Legs castaneous except ground color lateral coxae, with darker fasciae on femora, proximal pretarsal claws ground color, piceous distal pretarsi claws. Fore femora with proximal spine straight, longest, most acutely angled, secondary spine and tertiary spines curving distally, tertiary spine slightly smaller and parallel to secondary spine, and very small triangular apical spine, all spines castaneous with piceous tips. Tibial spurs and combs castaneous with piceous tips. Legs with long golden pile. Meracanthus broadly triangular, pointed with tip curving slightly mediad, ground color, extending posteriorly to anteromedial opercular margin. Female meracanthus broadly triangular, pointed, extending beyond posterior margin of operculum, ground color.

Opercula. Male operculum ground color with piceous base, base expanding laterally, lateral margin castaneous posterior to ventral curve, covered with short silvery pile radiating long golden pile, lateral margin extending ventrally at right angle from base, bent again at approximate right angle to form lateral margin parallel to long body axis, angled slightly mediad posterior to base, posterolateral margin curved to straight posterior margin, medial margin semicircular, not meeting medially, anteromedial margin transverse to lateral meracanthus where it curves anteriorly to base, not covering tympanum, reaching to anterior of sternite II near medial terminus. Female operculum ground color, shape similar to male with narrower medial point and smaller reaching only to middle of meracanthus, not covering tympanal cavity, covered with and radiating long golden pile.

Abdomen. Abdominal tergites ground color with lighter posterior margin covered with short golden pile, long golden pile on lateral tergites II–III, lateral tergites VI–VII and all of tergite VIII. Timbal cover absent, timbal exposed but only lateral margin visible. Male sternite I piceous, sternite II castaneous medially, ground color laterally, sternites III–VII ground color with posterior sternite VII darker, castaneous in some paratypes, sternite VIII ground color in holotype, castaneous in male paratypes, sternite VIII expanding from base, angled mediad to transverse terminus, open U-shape when viewed from the posterior, epipleurites color, short silvery pile on ventral segments, long golden pile radiating from sternites II, VII and VIII. Female abdominal segment 9 ground color, dorsal beak with piceous posterior margin, covered with short golden pile and radiating long golden pile. Dorsal beak curved dorsally, longer than castaneous anal styles, posterior margin of abdominal segment 9 sinuate. Female sternite 1 castaneous, remaining sternites ground color, epipleurites ground color, sternites covered with short and long golden pile. Female sternite VII with deeply curved notch almost reaching anterior margin, margin of notch extending as a small triangle beyond smoothly curving posterior margin.

Genitalia. Male pygofer ground color with castaneous ventral margin, tip of dorsal beak piceous, pygofer covered with short golden pile. Dorsal beak narrow, extending slightly beyond castaneous anal styles, anal styles piceous in one paratype. Pygofer basal lobe angled lateral from base, curving mediad at an approximate right angle in the middle with flattened distal terminus, basal pygofer lobe extension broad at base, curving and becoming significantly narrowed terminating in two narrow extensions, the anterior one very thin, the posterior extension more of an elongate triangle, radiating long, dense golden pile from angle and mediad extension. Upper pygofer lobes flattened, short, with terminus forming an approximate right angle. Claspers smoothly curved around aedeagus, base with extended point from medial anterior margin on either side of midline, posterior extensions flattened, semi-circular laterally and posteriorly with straight medial margin when viewed from above, radiating dense, long golden pile. Aedeagus dark castaneous, tubular with one terminal spine and dark tawny, elongated, flattened, sinusoidal terminal membrane that terminates in a point.

Gonocoxite IX ground color with castaneous posteromedial margin. Female gonapophyses VIII and IX dark castaneous, gonapophysis X piceous, tip extending beyond dorsal beak with radiating golden pile.

MEASUREMENTS (MM). N = three males or one female, mean (range). Length of body: male 19.25 (19.15– 19.40), female 21.45; length of fore wing: male 24.45 (24.30–24.65), female 26.20; width of fore wing: male 9.18 (9.00–9.30), female 9.55; length of head: male 3.35 (3.30–3.40), female 3.40; width of head including eyes: male 6.85 (6.75–7.05), female 6.75; width of pronotum including suprahumeral plates: male 8.00 (7.80–8.20), female 7.85; width of mesonotum: male 6.67 (6.55–6.75), female 6.50.

DIAGNOSIS. Herrera quadrimacula n. sp. can be distinguished from the majority of Herrera species by the lack of prothoracic markings and the presence of mesothoracic marking. Only H. ancilla , H. aurenigropilosa Sanborn, 2019c , and H. turbida ( Jacobi, 1907) have the same pattern of dorsal thoracic markings. This new species can be quickly distinguished from H. aurenigropilosa by the contrasting abdominal color, dense, radiating piceous pile, the markings along the parapsidal suture, between and lateral to the anterior arms of the cruciform elevation, the transverse posterior operculum margin with a very thin medial extension, and the long, golden pile radiating from the pygofer in that species. The larger body size (greater than 19 mm vs less than 15 mm), generally contrasting abdomen color, and mesothoracic mark on the anterior midline quickly distinguish H. ancilla from the new species. Finally, the large amount of piceous pile radiating from the dorsum of all body regions and the markings surrounding the submedian sigillae rather than forming four spots quickly distinguish specimens of H. turbida from this new species.

DISTRIBUTION. The species is known only from the type locality of Moyabamba , Peru.
