REMARKS. This is a small species with significant linear markings of the head and thorax. It has many characteristics similar to C. pictilis n. sp. but can be differentiated quickly by the head of H. signifera n. sp. being wider than the mesothorax and the lack of pygofer basal lobe appendages.

ETYMOLOGY. The name is in reference to the markings on the head and thorax (L., signifera , bearing marks, figures, signs).

DESCRIPTION. Ground color tawny marked with castaneous and piceous, tawny replaced with castaneous in two paratypes.

Head. Head slightly wider than mesonotum, dorsal head piceous except tawny lateral and anterolateral vertex, anterior and lateral supra-antennal plate, and posterior to eye, covered with short golden pile dorsally, longer pile radiating from dorsal head, long silvery pile posterior to eye. Ocelli rosaceous, eyes dark castaneous. Ventral head tawny except piceous mark on posteromedial of lorum along margin of anteclypeus. Postclypeus centrally sulcate with eleven transverse ridges, tawny except castaneous fascia on dorsal surface posterior to transverse ridge, greenish-tawny or castaneous in some paratypes with piceous mark on dorsal surface. Anteclypeus tawny with piceous lateral margin along lorum. Ventral head with short silvery pile, long pile radiating from lorum, gena, postclypeus and anteclypeus, white pubescence on lateral postclypeus and medial gena. Mentum tawny, labium tawny becoming piceous distally with castaneous tip. Rostrum reaching to anterior of hind coxae. Antennal segments dark tawny, distal segments castaneous in some paratypes.

Thorax. Dorsal thorax tawny marked with castaneous and piceous. Prothorax with tawny, piceous marks in anterior of lateral fissure not reaching anterior margin, in lateral ambient fissure continuing along posterior ambient fissure to either side of midline, on central lateral disc, on dorsolateral disc, piceous fascia medial to posterior lateral fissure recurving and expanding mediad from posterior terminating on disc and next to posterior paramedian fissure, curved fascia anterior to posterior half of paramedian fissure, extending into anterior paramedian fissure in some paratypes, castaneous fascia on dorsal midline not reaching anterior or posterior margins, transverse castaneous mark anterior to ambient fissure midline, sparse golden pile on dorsal surface, more dense in fissures. Pronotal collar tawny, radiating long golden pile. Mesothorax tawny, margins of submedian and lateral sigillae marked with piceous, mark is castaneous on anterolateral half of lateral sigillae in holotype and about half the paratypes, curved piceous marks between anterior arms of cruciform elevation with scutal depressions on lateral terminus and anteriorly extending along midline. Sparse golden pile on dorsum, longer pile radiating from dorsum, longer and denser in wing groove, on posterior margin and between anterior arms of cruciform elevation. Metanotum tawny with castaneous mark on anterolateral margin, golden pile on posterior margin. Ventral thoracic segments tawny with piceous marks on basisternum 2 and basisternum 3. Thoracic sternites covered with dense silvery pile.

Wings. Fore wing and wings hyaline with eight and six apical cells respectively. Venation tawny at base becoming darker distally except piceous on base and distal half of anal vein 2 + 3, pterostigma present, small castaneous spots on base, basal membrane of fore wing grayish with darker posterior, mottled with red in one paratype. Hind wing venation coloration similar to fore wing. Anal cell 3 along anal vein 3 and medial margin, 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 cells 1 and 2 and marginal area of hind wing along anal cell 1.

Legs. Legs light tawny, with castaneous mark on lateral coxae, and distal pretarsi, pretarsal claws ground color at base with castaneous tips. Fore femora with proximal spine largest, most angled, secondary spine less angled and smaller than primary spine with curved posterior, tertiary spine about the same size and parallel to secondary spine with greater posterior curve, and very small triangular apical spine extending from distal tertiary spine base, all spines ground color at base becoming castaneous at tip. Tibial spurs and combs tawny with castaneous tips. Legs with long golden pile.

Operculum. Male operculum tawny with castaneous spot on lateral base, piceous on proximal lateral margin becoming castaneous, covered with short silvery pile radiating long golden pile, lateral margin straight angled mediad posterior to base, obliquely angled posterolateral margin, posterior margin straight to medial meracanthus where it curves anteriorly to semicircular medial margin, not meeting medially, anteromedial margin transverse to lateral meracanthus where it curves to base, not covering tympanum posteriorly or anteromedially, reaching to anterior of sternite II medially but not laterally, domed laterally. Meracanthus broadly triangular, pointed, tawny with castaneous spots on anterior and posterior base, extending posteriorly to anteromedial opercular margin.

Abdomen. Abdomen tergites tawny with castaneous lateral margins, auditory capsule castaneous, castaneous spots on lateral tergite 1, anterior midline of tergite 2, anterior dorsolateral and posterior margin of tergite 8, tergites covered with long and short golden pile, castaneous restricted to posterolateral tergite 8 in female paratypes. Timbal cover absent, timbal completely exposed with five long ribs and four intercalary ribs. Male sternites and epipleurites tawny, sternite III with castaneous spot on midline near posterior of segment, sternite VII with larger castaneous spot on midline covering most of segment extending to posterior margin, sternite VIII castaneous with lighter lateral margin, sternite VIII pentagonal when viewed from the ventral surface, flat when viewed from the posterior, long golden pile radiating from ventral segments. Female sternites tawny with castaneous spot on midline of sternites III–VII mediolateral, becoming darker and larger in posterior sternites so that sternite VII is piceous medially bordered by castaneous with tawny anterolateral margins. Female sternite VII with single medial notch, small curved extension on either side of notch connecting to straight posterior margin angled posteriorly so that posterolateral corner is widest part of sternite. Female abdominal segment 9 dark tawny with castaneous fascia on anterior dorsolateral surface, wider fascia with darker posterior on lateral surface terminating posterior to stigma, and piceous ventral and posterior margins, radiating long golden pile. Dorsal beak twice as long as piceous-gray anal styles. Posterior margin of abdominal segment 9 sinuate.

Genitalia. Male pygofer tawny, with castaneous anterolateral surface, dorsolateral surface, dorsal beak, pygofer basal lobe and upper pygofer lobes dark castaneous with piceous tips, anterior clasper margin piceous. Dorsal beak narrow, extending beyond light castaneous anal styles. Pygofer basal lobe extended, finger-like with hooked tip, angled mediad. Upper pygofer lobes flattened, with a large triangular extension separating from the posterior spinelike extension. Claspers hemispherical when viewed from above, meeting medially, forming a V-shaped notch surrounding aedeagus when viewed from posterior, radiating dense, long golden pile. Aedeagus flattened with slightly widening tip bearing two short pseudoparameres, castaneous with a tawny terminal membrane.

Female gonocoxite IX dark castaneous. Gonapophysis IX castaneous, gonapophysis X dark castaneous anterolaterally, ground color distally. Ovipositor sheath extends beyond dorsal beak. Long golden pile radiating from ovipositor sheath.

MEASUREMENTS (MM). N = ten males or three females, mean (range). Length of body: males 14.81 (13.1–15.75), females 16.08 (15.05–16.8); length of fore wing: males 18.63 (16.75–19.85), females 20.00 (19.35–20.5); width of fore wing: males 7.38 (6.8–7.9), females 7.72 (7.45–7.85); length of head: males 2.88 (2.7–3.0), females 2.82 (2.7– 2.9); width of head including eyes: males 5.46 (5.0–5.65), females 5.52 (5.35–5.65); width of pronotum including suprahumeral plates: males 6.19 (5.65–6.75), females 6.43 (6.3–6.6); width of mesonotum: males 5.27 (4.8–5.55), females 5.52 (5.4–5.6).

DIAGNOSIS. Herrera signifera n. sp. can be distinguished from H. concolor n. sp. and H. criqualicae n. comb. by the lack of markings in those species. Similarly, H. ancilla , H. coyamensis , H. infuscata , H. melanomesocranon n. sp., H. phyllodes n. sp., and H. umbraphila all lack dorsal thoracic markings. Both H. lugubrina lugubrina and H. laticapitata are primarily piceous species. Herrera freiae n. sp., H. lugubrina compostelensis , H. guianaensis n. comb., H. humilistrata , H. quinimaculata n. comb., H. sigillata and H. turbida all lack the transverse piceous fascia in the entire pronotum ambient fissure. Only the Panamanian H. nigrotorquata also has a transverse piceous fascia in the entire ambient fissure of the pronotum but can be distinguished by the mesothoracic markings surrounding both the lateral and submedian sigillae in the new species while they are restricted to surrounding the submedian sigillae in H. nigrotorquata .

DISTRIBUTION. The species is known only from the type series collected in the Departments of Cochabamba and Santa Cruz.
