Etymology. The name petilunca  is a combination of petilus (L. thin) and uncus (L. hook or barb) in reference to the flattened uncus of the males.

Ventral head green, tawny in some paratypes, small castaneous mark on medial lorum at junction with postclypeus and anteclypeus. Thick white pubescence on ventral head. Postclypeus green, ventral side flattened laterally and centrally with thin carina, piceous on dorsal surface forming transverse line with piceous supra-antennal plates. Postclypeus with eight transverse grooves, thick white pubescence on lateral postclypeus. Anteclypeus green with thick white pubescence.

Basal cell lightly clouded. Pterostigma present. Basal membrane of fore wing white mottled with green anteriorly becoming dark gray posteriorly. Infuscation on base of radius anterior 2 extending beyond radial crossvein in holotype but separated into two spots or only a proximal spot in some paratypes, radial crossvein, radiomedial crossvein, large spot on distal third of radius anterior 2 that expands over distal apical cell 1 and half of distal apical cell 2 and ambient vein to wing margin, longitudinal infuscation within apical cells 2–6, wing margin from wing apex to terminus of cubitus anterior 2, and on arculus extending into distal basal cell. Venation of hind wing tawny mottled with green, green median vein, distal veins castaneous mottled with green in some paratypes. Anal cell 3 and anal cell 2 along anal vein 3 dark gray mottled with green, piceous spot at base extending across base of anal vein 3, anal cell 1 and 2 along anal vein 2 and anterior cubital cell 2 along cubitus posterior vein dark gray. Small infuscation on wing margin, expanding across most of wing margin at apex.

Legs. Legs green striped with light castaneous, green replaced with tawny in some paratypes. Fore femora with elongated proximal spine adpressed against femur, secondary spine elongated, upright triangle with castaneous tip and very small tertiary spine, all green, tawny in some paratypes. Distal tibiae and tarsi light castaneous, tibial spurs and comb castaneous.

Operculum. Male operculum roughly triangular with smoothly rounded posterolateral margin, reaching to anterior of sternite II, green with castaneous spot on lateral and medial base, covered with white pubescence. Medial margin curved, extending to middle of trochanter barely covering tympanal cavity medially. Meracanthus pointed, green with a castaneous base not reaching to middle of operculum. Female operculum with rounded posterolateral margin, terminating medially at middle meracanthus reaching to posterior of sternite II, green or tawny with green margin and light castaneous spots on medial and lateral base, covered with thick white pubescence. Female meracanthus almost as long as operculum, tawny or green with a castaneous base. Opercula with long silvery pile radiating from margin.

Abdomen. Abdominal tergite 1 green, tergite 2 tawny anteriorly with piceous anterior margin and green posteriorly, completely green or piceous anterior margin incomplete in some paratypes, tergites 3–8 castaneous with green posterior margin, castaneous darker in more posterior tergites, tergites with black and silvery pile, black pile denser anteriorly, on dorsolateral surface and along posterior dorsal margin on midline and laterally, silvery pile on lateral tergite 2, posterolateral tergites 3–8, dorsolateral tergites 5–8, and posterior dorsal midline of tergites 2–8. Timbal cover recurved from anterior margin of tergite 2 exposing timbal dorsally and laterally with radiating silvery pile, approximate right angle at dorsal base, ventral margin slightly curved. Timbal with four large and one intercalary ribs, large spot on timbal plate. Female abdominal segment 9 castaneous darker on dorsal and dorsolateral surfaces and stigma, green posteriorly forming transverse green band anterior to dark castaneous dorsal beak with longitudinal green extension anteriorly dorsal to stigma about half the length of abdominal segment 9, covered with black pile dorsally and laterally, silvery pile ventrolaterally.

Genitalia. Male pygofer castaneous anteriorly, transversely tawny in middle and green posteriorly, tawny between pygofer lobes, with curved distal shoulder, dorsal beak arching, with long golden pile dorsally, laterally and radiating from posterior margin. Pygofer basal lobe indistinct, pygofer upper lobes tawny, flattened and elongated with central depression, tip separated from pygofer with rounded apex. Anal styles castaneous with tawny base, base green in some paratypes, with radiating golden pile, anal tube green. Median uncus lobes tawny with castaneous spot dorsomedially, tawny replaced with green in some paratypes, and curved posterior, lateral uncus lobes large and flattened, green at base becoming castaneous at apex, dark castaneous on lateral margin, lateral uncus lobes curve around medial uncus lobe forming a flat plate with deep U-shaped notch on posterior, lateral margin curving laterad and bending downward just past half length then extending posteriorly at a slight angle mediad before bending sharply mediad to rounded terminus where it forms the U-shaped notch on the posterior, basal lateral uncus lobes rounded radiating long golden pile, medially forming a tubular constriction around aedeagus. Aedeagus tubular, dark castaneous.

Female gonapophyses VIII castaneous, gonapophyses IX piceous extending to posterior tip of dorsal beak with radiating golden pile. Gonocoxite IX tawny or light castaneous. Anal styles castaneous with green base.

Measurements (mm). N = 9 males or 10 females, mean (range). Length of body: male 22.82 (21.1–24.9), female 20.73 (19.5–21.9); length of fore wing: male 31.46 (29.4–34.3), female 30.44 (28.8–32.0); width of fore wing: male 9.66 (8.8–10.4), female 9.34 (8.6–10.1); length of head: male 2.89 (2.6–3.2), female 2.87 (2.7–3.1); width of head including eyes: male 7.36 (6.9–7.8), female 7.29 (6.8–7.7); width of pronotum including suprahumeral plates: male 8.91 (8.0–9.7), female 8.99 (7.9–10.1); width of mesonotum: male 6.82 (6.6–7.4), female 6.91 (6.0–7.7).

Diagnosis. The generic characters with also distinguish the species. The shape of the uncus, the abdominal coloration pattern, and the infuscation pattern of the wings quickly separate males from other genera of Dazina. The abdominal coloration pattern along with the infuscation pattern of the wings distinguishes female specimens.

Distribution. The species appears to be distributed over a wide range with the type series being collected in Alajuela, Heredia and Limón, Provinces, Costa Rica and the Departments of Izabal and Sacatepéquez, Guatemala.
