Diagnosis

Zischkaia warreni sp. nov. is distinguished from other species in the “ saundersii clade” by the absence of the VFW submedian line. Further distinctive characters include the rather prominent DHW submarginal and marginal line, reduced VHW ocellus in M 1 -M 2 combined with the ocellus in M 2 -M 3 being more than twice as large (in terms of diameter) and the median line and submarginal line being fused immediately after 2A in males. Additional characters are also discussed in the relevant sections of other species.

Etymology

This specific epithet is in honor of our good friend, Andrew D. Warren, a prominent lepidopterist with a broad knowledge of butterflies. The specific epithet is to be considered a latinized masculine noun in the genitive case.

DORSAL FOREWING. Ground color brownish, distally darker; androconial scales absent; trace of submarginal band indistinct.

DORSAL HINDWING. Ground color similar to forewing, trace of submarginal and marginal band visible.

VENTRAL FOREWING.

VENTRAL HINDWING.

Female

FOREWING LENGTH. 26–27 mm (n = 6).

Similar to male except as follows: foretarsus first and second subsegments apparently fused; forewing more rounded and broad; ground color of both wing surfaces paler, posterior end of VFW discal line do not come close to submarginal line as in male. VHW area between postdiscal and submarginal line whitish (around ocelli).

FEMALE ABDOMEN AND GENITALIA ( Fig. 7 G–H): inter-segmental membrane between seventh and eighth tergite not pleated, but expanded with posterior edge forming a smooth, curving sclerotized band anterior to ostium bursae that seamlessly borders the broad, sclerotized plate of lamella antevaginalis, which narrows ventrally to encircle ostium bursae and is indented throughout with the edges forming raised lip; eighth abdominal segment lateral side with sclerotized plate and with spiracle near dorsal margin, ventrally connected to lamella antevaginalis as sclerotized stripe, fused below ostium bursae as ‘arm’; ductus bursae membranous; origin of ductus seminalis close to ostium bursae; corpus bursae roughly oval in dorsal view, extending to third abdominal segment, with two signa in middle, parallel to each other.

Variation

The VFW submarginal and marginal lines are more or less fused in cell Cu 2 in some specimens, whereas they are placed rather further apart in other specimens.

Distribution ( Fig. 14 )

This species is known to date from southeastern to southern Brazil, in the states of Rio de Janeiro, Minas Gerais, São Paulo, Paraná and Santa Catarina . The geographic distribution of Z. warreni sp. nov. is apparently confined to areas associated with plateaus with Araucaria forest in middle to high elevations of southern Brazil, not extending beyond Serra Geral in the west. This distributional pattern is distinct from its potentially sympatric species Z. pacarus , which is also found in low elevation areas in the Paraná drainage and in the Atlantic coastal zone.

Remarks

The evidence from molecular data (see Fig. 1 and Table 4 ) and morphological distinctiveness documented above leaves no doubt as to its specific status. Adults of Z. warreni sp. nov. are similar in behavior to Z. pacarus , flying in association with the bamboo Merostachys ( Poaceae : Bambusoideae ) ( Fig. 16A, C ). The males’ flight is faster than that of the females, and individuals are commonly found engaged in patrolling flight. Both sexes are never found away from the bamboo and they are more active between the middle of the morning and the beginning of the afternoon. The restricted habitat of Z. warreni sp. nov. in Araucaria forests suggests that they likely use Merostachys as the caterpillar host plant.
