Description.— Orellana pollyae n. sp. is a green and black species marked with tawny (yellowish brown) ( Fig. 1 ). The green may fade to tawny with time of conservation.

Head ( Fig. 2 ): Not as wide as mesonotum, green with testaceous (brownish yellow) mark on lateral vertex extending from medial margin of eye to half the distance to lateral ocelli. Green faded to tawny in some paratypes. Ocelli ringed with fuscous (blackish brown) on testaceous base. Fuscous marks on medial supra-antennal plate, lateral to lateral and medial ocelli, lateral to lateral marks of lateral ocelli toward eye, a small spot on posterior head at level of mark lateral to lateral ocelli, and larger spot on posterior head at the level of inner medial angle of eye. A light testaceous mark curving between medial ocellus and frontoclypeal suture. Scape tawny, pedicel and proximal flagellar segments testaceous, distal flagellar segments fuscous. Long silvery pile posterior to eye. Postclypeus testaceous dorsally with medial green spot, ventral surface green medially, tawny laterally with ten testaceous transverse ridges, a medial testaceous line on posterior third in one paratype. Anteclypeus greenish tawny, two small fuscous spots on either side of midline centrally, absent in some paratypes. Rostrum tawny with the tip piceous (very black), a fuscous mark along midline of labium, extending to the medial curvature of opercula in male or sternite II in female. Gena tawny with testaceous spot medial to eye and fuscous mark along suture with postclypeus. Lorum tawny, testaceous medially along postclypeus. White pubescence on gena, lorum, and lateral postclypeus.

Thorax ( Fig. 2 ): Pronotum with medial green mark expanding posteriorly from anterior margin then constricting at level of medial paramedian fissure before expanding and contracting again before terminating anterior to ambient fissure. Disc tawny between paramedian and lateral fissures with irregular fuscous marking, testaceous between lateral fissure and ambient fissure and between paramedian fissure and medial green marking. Hooked green marking anterior to pronotal collar lateral to medial green marking. Fuscous markings along anterior margin, ambient fissure lateral to lateral fissure termini, and small transverse mark on midline of ambient fissure. Pronotal collar green, fuscous marks on anterior lateral margin continuing and thickening along anterior half of lateral angle before expanding across lateral angle to ambient fissure. Marks along lateral margin extend onto ventral surface of lateral angle and lateral margin of pronotum. Fine silvery pile within sutures. Mesonotum green with fuscous marks along parapsidal suture, within scutal depression, and across distal anterior arm of cruciform elevation. Submedian sigilla with triangular testaceous mark bordered with green medially, green faded to tawny in some paratypes. Testaceous mark expanding from between submedian sigillae to enclose scutal depressions before constricting between anterior arms of cruciform elevation. Lateral sigilla tawny with two testaceous linear marks, medial mark longer than lateral mark. Medial testaceous mark lightens and extends anteriorly from scutal depression between medial testaceous mark and parapsidal suture. Cruciform elevation green, bulbous between anterior and posterior arms, posterior margin fuscous, expanding over tergite 1. Silvery pile along lateral mesonotum, along parapsidal suture, between anterior arms of cruciform elevation, and lateral and posterior cruciform elevation. Wing groove marked with fuscous. Metanotum fuscous with testaceous medial posterior margin. Sternites greenish tawny covered with white pubescence. Fuscous marks on medial basisternum 2, medial margin of anepisternum 2, medial basisternum 3, additional marks on medial trochantin 2 and medial epimeron 2 in some paratypes.

Legs: Green and tawny, fuscous marks on distal coxa, medial trochanter, proximal femur, proximal and distal tibia, and distal fore femur. Three segmented tarsi and claws fuscous. Fore femora armed fuscous primary and secondary spines and small apical spine, proximal spine almost parallel to femur, secondary spine upright and more robust. Tibial spurs and tibial comb fuscous.

Forewings and hind wings ( Fig. 1 ): Forewings hyaline except distally infuscate. Forewings with eight apical cells, hind wings with six apical cells. Basal venation of forewing green, faded to testaceous in some paratypes, becoming testaceous distally. Basal cell rectangular, lightly clouded along anterior margin, coloration expanding toward base.

Measurements (mm).—N = 5 (2 males, 3 females), mean (range). Length of body: male 35.7 (35.0–36.4), female 31.9 (31.2– 32.8); length of forewings: male 48.0 (47.9–48.1), female 50.5 (49.2–53.0); width of forewings: male 16.7 (16.5– 16.9), female 16.8 (16.0–18.0); length of head: male 5.25 (5.2–5.3), female 5.13 (4.9–5.3); width of head including eyes: male 10.65 (10.5–10.8), female 10.5 (10.0–11.2); width of pronotum including suprahumeral plates: male 18.8 (18.6–19.0), female 19.17 (18.2–21.0); width of mesonotum: male 12.7 (12.5– 12.9), female 12.87 (12.0–13.6).

Diagnosis.— Orellana pollyae n. sp. can be differentiated from O. castaneamaculata by the infuscation on the forewing of O. pollyae n. sp. The almost completely opaque forewing of O. brunneipennis and O. pulla quickly differentiate these species from O. pollyae n. sp. The holotype of O. columbia was studied in the Natural History Museum (London) and can be differentiated by the ochraceous hue of the forewing, the lateral depression of the cruciform elevation and the abdomen being widest in the middle of O. columbia whereas the forewing are hyaline, the cruciform elevation is humped laterally and the middle and base of the abdomen being about equal in O. pollyae n. sp. Orellana bigibba is the most similar species to O. pollyae n. sp. due to the expansion of the cruciform elevation. The type series was misidentified as O. bigibba by more than one individual. For this reason, O. bigibba is illustrated in Figs. 10–15 to make comparisons and differentiation of specimens easier. The lateral expansion of the cruciform elevation is not as large in O. pollyae n. sp. and is not hemispherical and does not expend posteriorly over the abdomen of males as it does in O. bigibba . The lateral expansion of the pronotum is larger in O. bigibba , making the pronotum 1.88– 1.97 times as the width of the head whereas the pronotum is 1.76–1.82 times as wide as the head in O. pollyae n. sp. The infuscations on the forewing of O. bigibba are less expansive in comparison and can appear as four individual spots rather than the series of connected spots along the crossveins of apical cells 1–5 with two single spots as seen in O. pollyae n. sp. (although it should be noted that infuscation patterns can vary within species of the Zammarini ). The dorsal border to the timbal cavity of O. pollyae is L-shaped at the junction of the lateral and posterior margins whereas the dorsal border is smoothly curved in O. bigibba . Finally, the lateral uncus of O. pollyae curves at the terminus whereas that of O. bigibba terminates along the side of the median uncus.
