Paratypes. “ PERU Madre de Dios / nr Puerto Maldonado / Posadas Amazonas / lodge@ Rio Tambopata // S12 48.115 W69 18.019 / 609ft;(7–10)- X-2004 / C R Bartlett” one female (AFSC).
ETYMOLOGY. The name is a combination of ptycho- (Gr. ptyktos, folded) and -diropeda (Gr. deiropede, collar, necklace) in reference to the distinctive invagination on the lateral angle of the pronotal collar.
DESCRIPTION. Ground color of head and thorax greenish ochraceous marked with piceous, abdomen ochraceous marked with piceous. The head and thorax may be green in fresh specimens as the green regions vary in the two specimens.
Head. Head wider than mesonotum and lateral angle of pronotal collar, ochraceous with transverse piceous fascia through ocelli extending to middle of lateral vertex, mark extends anteriorly on frons to frontoclypeal suture to medial corner of supra-antennal plate, piceous posterior to eye. Head covered with short silvery pile dorsally, denser along frontoclypeal suture, longer and very dense posterior to eye. Ocelli red, eyes dark castaneous. Ventral head ochraceous with incomplete transverse piceous fascia extending across medial gena, piceous margin to eye, dense long and short pile on ventral head. Postclypeus centrally sulcate, greenish ochraceous with piceous in posteroventral sulcus, posterior margin and lateral transverse grooves, long silvery pile laterally and posteriorly. Anteclypeus piceous with greenish ochraceous medial and posterior carina not reaching posterior margin, covered with dense, long silvery pile. Mentum ochraceous, labium piceous, rostrum reaching beyond middle of basisternum 3. Scape ochraceous, remaining antennal segments piceous.
Thorax. Dorsal thorax greenish ochraceous marked with piceous. Prothorax ground color with piceous marks in anterior paramedian and lateral fissures, piceous and silvery pile within fissures, denser in paratype. Pronotal collar ochraceous, marked with green in paratype, curved indentation on posterior margin dorsal midline, pronotal collar lateral angle with right angle between posterior margin and middle of anterior lateral angle of pronotal collar. Mesothorax greenish ochraceous, piceous fascia along parapsidal suture not reach posterior suture, piceous spot on anterolateral lateral sigilla mostly concealed by pronotal collar, short silvery pile on anterior margin and between anterior arms of scutal depressions, sparse, long piceous pile between anterior arms of cruciform elevation in paratype, wing groove ochraceous with piceous fascia medially. Long, dense silvery pile on lateral mesonotum, radiating from posterolateral margin and in wing groove, cruciform elevation radiating short silvery pile posteriorly, long piceous pile radiating from cruciform elevation in paratype. Metanotum ochraceous with long, dense silvery pile. Ventral thoracic segments ochraceous except piceous basisternum 2, medial katepisternum 2, medial katepimeron 2, midline spot on basisternum 3, medial trochantin 3, and medial episternum 3. Thoracic sternites covered with dense white pile.
Wings. Fore wing and wings hyaline, distal ulnar cell 1, apical cells and wing margin with smokey appearance, radial and radiomedial crossveins slightly infuscated. Venation ochraceous at base becoming piceous distally, subcostal vein piceous beyond node, proximal half of anal vein 2 + 3 piceous. Basal cell ochraceous with hyaline border along base of cubitus anterior, pterostigma extending to about base of radius anterior 2, basal membrane of fore wing grayish, posterior darker, piceous fascia along posterior base of clavus. Hind wing venation proximally greenish or ochraceous becoming piceous distally. Anal cell 3 and anal cell 2 along anal veins 2 and 3, anal cell 1 along anal vein 2 grayish, infuscation at base and along grayish in anal cell 2.
Legs. Legs ochraceous with piceous on lateral coxae, piceous fascia on tibiae, fore tibiae with fascia extending almost from proximal joint, reduced in middle tibiae to about distal half and reduced to small mark near distal end in hind tibiae, two part tarsi and pretarsal claws mainly piceous striped with ochraceous, hind tarsi marked with piceous only at base and near distal end, pretarsal claws ochraceous with piceous tips. Fore femora with proximal spine angled, secondary spine upright about the same length as primary spine, tertiary spine very small, slightly angled, all spines piceous. Tibial spurs and tibial combs castaneous. Legs with short white pile and radiating long white pile. Meracanthus pointed, slightly curved mediad, ochraceous with piceous base, not reaching posterior opercular margin. Female meracanthus as in male except reaching beyond posterior opercular margin to middle of sternite II.
Opercula. Male operculum ochraceous with piceous spot on medial base next to meracanthus and on anterior and posterior lateral base, covered with long silvery pile, lateral margin slightly curved mediad, posterolateral margin forming an approximate equilateral triangle between lateral and posterior margin, posterior margin straight before rounded medial margin, not meeting medially, reaching to anterior of sternite II, barely covering tympanal cavity medially and posteriorly. Female operculum similarly shaped and colored, reaching to medial meracanthus medially and posterolateral extension to posterior of sternite II.
Abdomen. Abdominal tergites 1–7 ochraceous with piceous anterior margin, lateral tergites in holotype darkened to testaceous, tergite 8 ochraceous, piceous expanding posteriorly on lateral tergite forming piceous spot, tergites covered with dense golden pile, denser laterally and anteriorly, tergites 3–8 with radiating long piceous pile on dorsoposterior tergites. Timbal cover testaceous margined with piceous, ventrolateral margin angled dorsally to semicircular apex, dorsolateral margin straight smoothly curving to posterior timbal cavity margin, incomplete exposing timbal dorsally. Timbal white and ochraceous partially visible through opening in timbal cover. Male sternites ochraceous, sternite I marked with piceous posteriorly, sternite VII with testaceous posterior margin sternite, sternites III–VII translucent, sternite VIII an open U-shape when viewed from the posterior, long white pile radiating from sternites, long golden pile radiating from sternite VIII, epipleurites ochraceous covered with long white pile, spiracles surrounded by white pubescence.

DIAGNOSIS. Fidicinoides ptychodiropeda n. sp. is one of a group of species including F. determinata, F. ferruginosa Sanborn & Heath, 2014, F. lacteipennis (Distant, 1905d), F. picea, F. pronoe and F. vinula Stål, 1854 characterized by pile on the lateral mesonotum that gives the appearance of a lateral stripe but the genitalia of the new species is significantly different from all these species. The new species can be distinguished from F. ferruginosa and F. vinula by the ferruginous body coloration of these species. The new species can be distinguished from F. determinata by the piceous lateral mesonotal fascia and piceous markings on the submedian sigillae, the posterior margin of the timbal cavity is smoothly curved on the posterolateral margin but forms a right angle in the new species, the lateral male operculum is concave rather than convex as in the new species, the wide lateral pronotal collar that lacks the folding characteristic of the new species, and the uncus lacks the very large, broad, flat medial extension of the lateral branch of the uncus found in the new species. Similarly, F. picea can be distinguished by the posterior margin of the timbal cavity that is smoothly curved on the posterolateral margin but forms a right angle in the new species, the wide lateral pronotal collar that lacks the folding characteristic of the new species, and the uncus lacks the very large, broad, flat medial extension of the lateral branch of the uncus found in the new species. Fidicinoides lacteipennis has a general appearance similar to F. ptychodiropeda n. sp. but can be distinguished by the smaller body size (body length 29 mm vs. 36.5 mm, wingspan 94 mm vs. 100.4 mm), the abdomen widening to tergite 4 rather than having parallel sides like the new species, the darker abdomen contrasting the head and thorax coloration rather than being monochromatic like the new species, the presence of mesonotal markings, and the wide lateral angle of the pronotal collar that lacks the folding characteristic of the new species. The most similar species is F. pronoe but the new species can be distinguished quickly by the fold in the lateral pronotal collar and the large, square lateral uncus lobes of the new species.
DISTRIBUTION. The species is only known from the type series collected near Puerto Maldonado, Madre de Dios, Peru.
