Pierella hyalinus explained

Pierella hyalinus, the glassy pierella or the hyalinus pierella,^[1] is a species of butterfly in the brush-footed butterfly family Nymphalidae. It was first described by Johann Friedrich Gmelin in 1790.

Description

Pierella hyalinus is visually similar to the related Pierella lena.^[2] Early researchers applied the moniker Pierella hyalinus to the insects found in the Amazon and Trinidad. M.P. Clifton was of the opinion that there existed a species complex between P. hyalinus and P. lena. P. hyalinus is differentiated from P. lena by the M3 terminal branch of the dorsal hindwing being prolonged, forming a sickle projection on the outer margin, and the marginal region with bluish scales.^[3]

Subspecies

There are four known subspecies of Pierella hyalinus:^[4]

• Pierella hyalinus hyalinus (Gmelin, [1790]) (Suriname, Trinidad)^[5]
• Pierella hyalinus extincta Weymer, 1910 (Brazil)
• Pierella hyalinus schmidti Constantino, 1995 (Amazon Trapeze of Brazil, Colombia, and Peru)^[6]
• Pierella hyalinus velezi Constantino, 1995 (Guainía, Colombia)
