Diagnosis. Pierella kesselringi sp. nov. can be distinguished from P. keithbrowni sp. nov. by the DFW yellow stain restricted to discal area and wings completely brown in females. Androconial patch characterized by the large and well-marked dark rounded central area ( Fig. 33 ). Female genitalia present the papillae anales with a welldeveloped and curved posterior aphophysis similar to P. angeloi sp. nov., but the ductus bursae is 1.5 times longer than corpus bursae. Ostium bursae with a sclerotized projection from the ductus bursae, similar to P. chalybaea stat. rest, but the paired signa of the latter is located on the underside of the corpus bursae ( Figs 56–57 ).

Description. Head. Front brown. Antennae dark brown. Labial palpi with elongated scales, white on the underside and mixed with brown and light brown scales on the upper side. Thorax. Prothoracic legs white; meso and metathoracic legs brown on the upper side and lighter on the underside. Forewing length: male: 33–36 mm (n = 22); female: 36–38 mm (n = 8). Forewing upper side ( Figs 17, 19 ). Mostly brown, with a yellow stain covering about 2/3 of the wing. Discal cell with three black dots. Forewing under side ( Figs 18, 20 ). Similar to DFW. Mostly light brown with outer margin darker in males. Three reduced incomplete ocelli in R5-M1, M1-M2 and M2-M3. Hind wing upper side ( Figs 17, 19 ). Mostly dark brown, lighter towards to base. Five incomplete ocelli in Rs-M1, M1-M2, M2-M3, M3-CuA1 and CuA1-CuA2, the second and the fourth are the largest. Four black spots on the basal region. Four convex dark brown lines, the most distal thicker and well-marked. Androconial patch with a large and wellmarked dark rounded central area ( Fig. 33 ). Hind wing under side ( Figs 18, 20 ). Similar to DHW. Outer margin brown and five incomplete ocelli in Rs-M1, M1-M2, M2-M3, M3-CuA1 and CuA1-CuA2.

Male genitalia. Similar to P. lamia (see Figs 36–41 ).

Female genitalia ( Figs 56–57 ). Tergum VIII trapezoid. Papillae anales with setae at the distal area, approximately 2/3 taller than longer, sclerotized at the basal half. Sternum VIII not fused with the lamella antevaginalis. Corpus bursae completely membranous, with paired signa located dorsally; ductus bursae about three times longer than corpus bursae, anterior portion sclerotized and dilated; ostium bursae with a sclerotized projection out from ductus bursae.

Distribution ( Fig. 62 ). This species occurs in the Northeast Brazil (Paraiba, Pernambuco, Alagoas and Sergipe states) in Caatinga province (Chacoan dominion) and Atlantic and Parana Forest provinces (Parana dominion).

Host plant. Unknown.

Etymology. This species honours to Swiss-Brazilian naturalist Hans Jorge Kesselring, who collected several specimens examined in the present study.

Remarks. Kesselring & Ebert [1982] suggested this species as a new one close related to “ Pierella lamia ” in their list of butterflies from “ Mata do Buraquinho”, Paraíba, Brazil, but they did not described this species. Paluch et al. (2011) pointed out that individuals collected in the Ecological Park João Vasconcelos Sobrinho, Caruaru, Pernambuco, Brazil might constitute a distinct subspecies of P. lamia , however they also did not describe that. In the present study, morphological evidences from androconial patches and female genitalia were founded and its support the Kesselring & Ebert’s opinion, in addition to the differences in the chromosomal number on this species (Brown et al. 2007).
