Pierella stollei boliviana F.M. Brown, 1948 , p. 74–75.—D’Abrera, 1988, p. 731. Pierella hyceta (Hewitson, 1859) ; Lewis 1973, p. 65 [misidentification]. Pierella lamia boliviana ; Lamas, 2004, p. 206.

Diagnosis. Pierella boliviana stat. nov. resembles P. luna ( Fabricius, 1793) in size (male FW length: 38–39 mm [n = 3]; female FW length: 38–42 mm [n = 3]) and HW shape, but the ocelli of P. luna are restricted to Rs-M1 and M1- M2. Within the “ P. lamia species group”, P. boliviana stat. nov. is closely related to P. lamia , but differs from that by the straight HW costal margin and the outer margin projected at M1. There are four incomplete ocelli on VHW, but some individuals might have a reduced ocellus in M2-M3. VHW post-discal and postmedian lines are straight. Androconial patch is characterized by a well-marked, elongated dark central area ( Fig. 31 ). Tegumen is dorsally larger than in P. lamia , uncus straight and tapering at the apex, valva with apex projected out upwards and serrated with some reduced spines on sacculus, aedeagus rounded at the anterior portion ( Figs 42–47 ). In female genitalia, the papillae anales have a developed and curved posterior aphophysis similar to P. angeloi sp. nov., corpus bursae almost the same length of ductus bursae, and with a paired signa on the ventral side ( Figs 52–53 ).

Distribution ( Fig. 62 ). This species is only known from the departments of Santa Cruz and Cochabamba, Bolívia, in the Yungas province of the South Brazilian dominion.

Host plant. Unknown.

Remarks. Brown (1948) described Pierella stollei boliviana based on several specimens from Rio Yapacani, Santa Cruz, Bolivia. The holotype is deposited at the Carnegie Museum of Natural History, USA (CMNH) and paratypes are deposited at CMNH and NHM. Lamas (2004) proposed a new combination, Pierella lamia boliviana . Currently, P. s t o l l e i Ribeiro, 1931 is a subspecies of P. astyoche (Erichson, [1849]) ( Lamas 2004). All P. astyoche subspecies have a lighter transverse band in the submarginal region of the VFW and VHW, not present in P. lamia . Based on the genitalia of both sexes and the wing colour pattern, there is no doubt that P. boliviana stat. nov. is a valid species and distinct from P. lamia .
