Remarks. The pile forming a stripe on the lateral mesonotum in Fidicinoides ininiensis n. sp. is similar to several species of the genus but the new species has distinct genitalia from all these species. The new species is a brownish ochraceous (ochraceous green in some specimens especially on head and pronotal collar) species marked with castaneous and fuscous. Related species are often green when live.
Etymology. The name is a combination of inini - (Inini, former territory of French Guiana) and - ensis (L., suffix denoting place, locality) in reference to the past name for the inland region of French Guiana where the species was collected.
Description. Ground color of head and thorax brownish ochraceous marked with piceous and castaneous, abdomen brownish ochraceous marked with piceous and castaneous. The head and thorax may be green in some paratypes but the chemicals in the light traps have altered most specimens to the brownish ochraceous coloration. Specimens from Pointe-de-Vue often have crystalline residue on the surface from the fluid in the light traps.
Head. Head wider than mesonotum and lateral angle of pronotal collar, ground color with incomplete transverse piceous fascia surrounding all ocelli, frons, extending laterally almost to middle of lateral vertex and to anterior cranial depression, mark extends anteriorly on frons to frontoclypeal suture to posteromedial corner and medial margin of supra-antennal plate, piceous posterior to eye, extending medially to posterior cranial depression in some paratypes, lateral vertex margin piceous along eye. Head with short silvery pile dorsally, densest on frons, longer and very dense posterior to eye. Ocelli reddish, ochraceous or greenish in some paratypes, eyes dark castaneous. Ventral head ground color with short transverse piceous mark on mediolateral gena, piceous margin to eye, and picous posteromedial lorum, dense long and short white pile on ventral head. Postclypeus centrally sulcate ground color, with piceous in posteroventral sulcus, all but posteroventral pair of lateral transverse grooves with lateral picous mark connected laterally around end of transverse ridges, long white pile laterally.

Length of body: males 34.75 (31.20–37.00), females 32.62 (31.00–34.10); length of fore wing: males 42.90 (40.75–44.00), females 42.82 (41.75–44.85); width of fore wing: males 13.21 (12.15–13.85), females 13.36 (12.80–14.40); length of head: males 5.59 (5.30–5.80), females 5.52 (5.15–5.80); width of head including eyes: males 14.70 (14.40–14.95), females 14.64 (13.90–15.15); width of pronotum including suprahumeral plates: males 14.20 (13.50–14.50), females 14.19 (13.35–14.60); width of mesonotum: males 12.47 (11.95–13.35), females 12.64 (11.50–13.35).
Diagnosis. Fidicinoides ininiensis n. sp. is one of a group of species including F. determinata (Walker, 1858b), F. ferruginosa Sanborn & Heath, 2014, F. lacteipennis (Distant, 1905b), F. picea (Walker, 1850), F. pronoe (Walker, 1850), F. ptychodiropeda Sanborn, 2020a, F. roberti (Distant, 1905b) and F. vinula (Stål, 1854) characterized by the appearance of a stripe on the lateral mesonotum produced by pile but the genitalia of the new species is significantly different from all these species. Fidicinoides roberti can be distinguished quickly by the infuscation on the fore wing radial and radiomedial crossveins, the ambient vein and marginal area of both fore wings and hindwings. The new species can be distinguished quickly from F. ferruginosa and F. vinula by the ferruginous body coloration of these species. In addition, the ratio or fore wing length to fore wing width is diagnostic to separate most species. The ratio in the new species is about 3.25 but about 2.92 in F. ptychodiropeda, 2.94 in F. lacteipennis, 3.01 in both F. ferruginosa and F. vinula, 3.02 in F. picea, and 3.05 in F. determinata. Only F. pronoe has a similar fore wing length to width ratio at about 3.23 but F. pronoe lacks the piceous lateral mesonotal fascia, the submedian sigillae are almost entirely piceous, the timbal cover is inflated instead of flat, the posterior margin of the timbal cavity is straight on the posterolateral margin instead of sinusoidal, the postclypeus extends anteriorly from the supra-antennal plates instead of forming a smooth curve along the front of the head, the frons is close to perpendicular to the dorsal head, fore wing apical cell 2 expands distally forming a more conical shape, the radiomedial crossvein intersects median vein 1 at about half distance instead of one-third distance from origin, the fore wing medial crossvein is straight instead of wavy, the uncus dorsal crest is upright instead of recurved, the median uncus lobes are lacking, the lateral branch of the uncus is strongly recurved, and the posterior largin of female sternite VII is smoothly curved lateral to the medial notch without the transverse portion of the margin found between the notch and the lateral posterior curve in the new species. The remaining species of the genus lack the lateral mesonotum stripe and have significant infuscation on the fore wing venation.
Distribution. The species is only known from the type series collected in Sa ü l Commune, French Guiana.
