| Popis: | Ptiloneura leonardoi n. sp. (Fig. 2) urn:lsid:zoobank.org:act: 13EFDBFB-79B6-4C5A-AF4A-2E35DD9B941F TYPE MATERIAL. — Holotype. Brazil • 1 ♂; Santa Catarina, Nova Teutônia; 27°09’1”S, 52°25’4”W; VI.1972; Fritz Plaumann leg.; INPA. HOLOTYPE CONDITION. — Head, fore and hind wings, phallosome, hypandrium, epiproct, and paraproct mounted on microslide. The remaining body parts are preserved in 70% ethanol. ETYMOLOGY. — The species honors Leonardo de Assis Castro, son of Marcelo Cutrim. GEOGRAPHICAL RECORDS. — Known only from the type locality, Brazil, Santa Catarina state, Nova Teutônia city, on Atlantic Forest in southeastern Brazil. DIAGNOSIS. — Central sclerite of the hypandrium with two curved, postero-lateral processes, distally acuminate, curved outward resulting in a U-shaped posterior concavity; side sclerites short, almost rectangular (Fig. 2G); forewings with a slender, marginal pigmented band from R4+5 to areola postica (Fig. 2B); mesal endophallic sclerite of phallosome transverse, with large, median, pointed process, and long, slender, postero-lateral processes (Fig. 2F). DESCRIPTION Male (holotype) Color. Compound eyes black, ocelli hyaline; head pattern (Fig. 2A). Scape and pedicel pale yellow, f1–f3 pale brown. Mx4 brown. Femora pale yellow; tibiae pale yellow with a brown band distally; tarsomeres 1-3 pale yellow. Forewing (Fig. 2B) veins brown, pterostigma brown with a median hyaline area, a brown spot in R 2+3 and R 4+5 at wing margin. Hindwings (Fig. 2C) hyaline. Morphology. Outer cusp of lacinial tips broad, with seven short denticles (Fig. 2A). Right forewing (Fig. 2B) pterostigma narrow proximally, wider in the middle; areola postica wide, tall, apically rounded; Rs shorter than its branches, slightly concave, R 2+3 almost straight, R 4+5 with a median concave curve; M stem concave proximally, then almost straight, with six primary branches. Right hindwing (Fig. 2C) Rs almost straight, R 2+3 straight, R 4+5 with a median concave curve; M with four primary branches, M 2 forked. Left forewing (Fig. 2D) differing from the right forewing in having M stem with five primary branches, M 5 forked, resulting in M 5a and M 5b. Left hindwing (Fig. 2E) differing from the right hindwing in having the M stem with four primary branches. Hypandrium (Fig. 2G) of three sclerites, central sclerite with with fields of long macrosetae on each side of the longitudinal midline, that do not reach the apices of the postero-lateral processes. Phallosome (Fig. 2F) side struts slender, V-shaped, anteriorly independent, long, narrow, distal ends almost triangular as an outward directed hook, not fused posteriorly to external parameres, these slender, proximally dilated, elongated, narrowing distally, with a field of pores and an apical end inwardly directed. Four pairs of endophallic sclerites, an anterior small pair with two acuminate projections, the longest directed inward almost touching in the middle and the short, directed outward; a lateral bow-shaped pair curved inward, proximally wide, triangular, distally narrow, with a radular end area; a posterior pair, long, slightly wide proximally, almost straight, slightly curved outward distally and a mesal triangular sclerite, with two wide lateral process distally rounded. Epiproct (Fig. 2H) rhomboid, with three short central setae, two long lateral and a set of posterior ones. Paraprocts straight based, broad, sensory fields with 33 trichobothria on basal rosettes, setae as illustrated (Fig. 2H). Measurements (in microns). FW: 5503, HW: 3618, F: 1310, T: 2249, t1: 879, t2: 67, t3: 165, f1: 927, f2: 904, f3: 567, Mx4: 270, IO: 545, D: 489, d: 317, IO/d:1.71, PO: 0.58. VARIATION. — There are variations in the fore and hindwing venation in this specimen as seen in the right forewing (Fig. 2B) with six primary branches differing from the left forewing (Fig. 2D) with five primary branches with M5 forked, resulting in M5 a and M5 b, and in the right hindwing (Fig. 2C) with four primary branches with M2 forked, resulting in M2 a and M2 b differing from the left hindwing (Fig. 2E) with four simple primary branches.
