REMARKS. The lack of body markings is similar to H. concolor n. sp. and H. criqualicae n. comb. but H. phyllodes n. sp. can be distinguished by its smaller body size, the castaneous posterior tergites, castaneous marking on the central sternites, the proportionately smaller head, and the shape of ulnar cell 3 and the medial cell in the fore wing.

ETYMOLOGY. The name is in reference to the leaf-like terminus of the male claspers (Gr., phyllodes , leaf-like).

DESCRIPTION. Ground color dark ochraceous, posterior abdomen marked with castaneous. Green may predominate in fresh specimens as there is some green on the abdominal segments of one female specimen.

Head. Head slightly wider than mesonotum, ground color without markings. Ocelli red. Eyes dark ochraceous, castaneous or castaneous and reddish in paratypes, short and long silvery pile posterior to eye. Ventral head ground color. Postclypeus centrally sulcate from anterior to posteroventral margin to around apex, with ten transverse grooves, short silvery pile on lateral margin, some medial castaneous marks on transverse ridges in some paratypes. Anteclypeus ground color. Long silvery pile on ventral head, very thick on lorum, ventroposterior postclypeus and anteclypeus. Mentum ground color, labium ground color with castaneous lateral fascia on distal third and piceous tip, reaching to anterior or middle of hind coxae. Scape, pedicel and first flagellar segment ground color proximally, castaneous distally, proportion of castaneous increasing in distal segments, remaining antennal segments piceous, castaneous in some paratypes.

Thorax. Dorsal thorax ground color. Pronotum unmarked, sparse silvery pile within fissures. Pronotal collar ground color, sparse silvery pile laterally in one paratype. Mesonotum ground color, unmarked except for piceous mark on posterior wing groove margin with lateral cruciform elevation, slight mottling in lateral and submedian sigillae where muscles attached internally. Metanotum ground color. Short silvery pile between anterior arms of cruciform elevation, lateral cruciform elevation and radiating from dorsoposterior metanotum, long silvery pile on posterior half of lateral mesothorax, posterior mesothorax, radiating from posterior wing groove, and on lateral 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 ground color, except piceous anal vein 2 + 3, pterostigma present. Basal membrane grayish with darker posterior margin. Hind wing venation ground color. Anal cell 3 gray, anal cell 2 along proximal anal vein 3, anal cell 3 along anal vein 3 margined with gray.

Legs. Ground color except castaneous distal margin of tibiae, pretarsal claws castaneous in middle with piceous tips, long golden pile radiating from legs. Fore femora with proximal spine longest and most oblique, secondary spine angled less than primary spine and of intermediate length, tertiary spine angled greater than secondary spine, secondary and tertiary spines curving to tip, spines ground color with castaneous tips. Tibial spurs and comb ground color with castaneous tips.

Operculum. Male operculum large for the genus, ground color covered with short silvery pile and radiating longer pile, lateral margin smoothly curved to rounded posterior margin forming semicircular form, rounded medial margin, not meeting medially, with concave anteromedial margin to base, covering tympanum reaching to anterior of sternite II, domed laterally. Meracanthus ground color, broadly triangular, pointed, just passing anterior opercular margin. Female operculum and meracanthus similarly shaped and colored, operculum reaching to posterior of sternite II, meracanthus to posterior opercular margin.

Abdomen. Abdomen tergites ground color, castaneous spot on lateral male tergite 1, castaneous posterior margins on tergites 5–8, castaneous expanding in posterior tergites with tergite 8 completely castaneous, posterior margin of tergite 7 piceous in some paratypes, marking restricted to posterolateral surfaces of one female what has greenish abdominal tergites, tergites covered with silvery pile, long silvery pile radiating from lateral tergites 7 and 8. Timbal completely exposed, timbal with 11 long ribs and ten intercalary ribs. Male sternites ground color, sternites IV–VIII with medial castaneous mark, proportion of castaneous increasing in posterior sternites, sternite VIII with smoothly curved posterior margin, epipleurites ground color, sternites and epipleurites covered with short silvery pile and radiating long silvery pile. Female sternite VII dark castaneous on midline, with deeply curved notch almost reaching anterior margin, margin of notch extending to point posteriorly producing triangular extension beyond lateral posterior margin, lateral posterior margin curving to anterolateral terminus. Female abdominal segment 9 ground color with U-shaped castaneous mark on dorsolateral surface lighter anteriorly, castaneous ventral margin, piceous spot on ventroposterior curve, and piceous dorsal beak, covered with short silvery pile and radiating long silvery pile. Dorsal beak extending beyond anal styles, anal styles piceous at base, ground color distally. Posterior margin of abdominal segment 9 sinuate.

Genitalia. Male pygofer ground color, dorsal beak darker. Dorsal beak narrow, extending at right angle from straight distal shoulder, covered with short and long silvery pile. Pygofer upper lobe small, triangular, bent at approximate right angle at base. Pygofer basal lobe extended, adpressed to pygofer, curving mediad, dense, long golden pile radiating from distal region, particularly dense at tip, long golden pile radiating from pygofer margin at level of basal lobe appendage. Uncus absent, claspers small meeting posterior to anal styles and recurving laterally forming a V-shaped notch. Basal lobe appendage flattened, broad at base curving at right angle to produce thin extension that expands into a leaf-like terminus with two large extensions, one with a single point the other bifurcating to form two points. Aedeagus castaneous with a tawny terminal membrane.

Female gonocoxite IX ground color or castaneous, with piceous medial margin. Gonapophysis IX and X castaneous. Ovipositor sheath extends beyond dorsal beak. Long golden pile radiating from ovipositor sheath, ovipositor sheath covered with short golden pile.

MEASUREMENTS (MM). N = 2 males or 2 females, mean (range). Length of body: males 15.9 (15.5–16.3), females 16.85 (16.4–17.3); length of fore wing: males 21.70 (21.15–22.25), females 21.23 (21.0–21.55); width of fore wing: males 8.03 (8.0–8.05), females 7.68 (7.65–7.7); length of head: males 2.30 (2.15–2.55), females 2.58 (2.5–2.65); width of head including eyes: males 5.48 (5.45–5.5), females 5.38 (5.35–5.4); width of pronotum including suprahumeral plates: males 6.40 (6.25–6.55), females 6.35 (6.0–6.7); width of mesonotum: males 5.33 (5.2–5.45), females 5.35 (5.35–5.35).

DIAGNOSIS. Herrera phyllodes n. sp. can be distinguished from H. concolor n. sp. by the lack of markings and larger body size (greater than 18.9 mm vs. less than 17.4 mm) in that species. Similarly, H. criqualicae n. comb. also lacks body markings but differs in the shape of the male and female opercula and genitalia. The primarily piceous bodies or bodies heavily marked with piceous distinguish H. lugubrina lugubrina and H. laticapitata from this new species. Herrera freiae n. sp., H. lugubrina compostelensis ,. H. guianaensis n. comb., H. humilistrata , H. nigrotorquata , H. sigillata , H. signifera n. sp. and H. turbida possess obvious piceous markings on the thorax. Herrera melanomesocranon n. sp. can be distinguished by its primarily piceous head. Herrera quinimaculata (Sanborn, 2011a) n. comb. can be distinguished by the five piceous spots on the dorsal mesothorax. The lack of piceous on the head and the non-contrasting abdomen distinguishes this new species from H. ancilla , H. coyamensis , and H. umbraphila . The Cuban H. infuscata has infuscation on the apex of the fore wings.

DISTRIBUTION. The species is known only from the type series collected in the Province of Nor Yungas.
