≡ Specklinia fragae Kollmann & Fontana (2008: 16) .

Type: — BRAZIL. Espírito Santo: Santa Teresa, Nova Lombardia , 750 m, 11 February 2005, L. Kollmann, A. P. Fontana & L. N. Lima 7386 (holotype: MBML 31780 !).

= Pabstiella dasilvae Chiron & Ximenes Bolsanello (2011: 141) , syn. nov.

Type: — BRAZIL. Bahia: Prado , 0 m, 2005, G. Chiron 9862 (holotype: HUEFS 179704 !).

Taxonomic Discussion: — Pabstiella dasilvae was described from southern Bahia at sea level. Due to its puberulent sepals, it was compared with some species of Pabstiella section Effusae ( Lindley 1842: 74) Gutiérrez, Toscano & E.C. Smidt (2021: 582) , such as P. fasciata ( Seehawer 2005: 458) Luer (2007: 119) and P. fusca ( Lindley 1836: 354) Chiron & Ximenes Bolsanello (2010: 56) . However, the presence of indumentum on the inner surface of the sepals is not restricted to a single group of species within the genus, and it can range from puberulent to pubescent or villose.

Pabstiella fragae was described three years earlier from Santa Teresa, Espírito Santo, in vegetation type called “Floresta Ombrófila Densa Montana ”. Upon comparing both publications and studied specimens, it becomes evident that they belong to the same entity, despite a difference in overall size. Plants from the lowlands of Bahia are smaller, with ramicauls no longer than 3 mm long and leaves up to 2.8 cm long, while those from the Serra do Castelo of Espírito Santo are larger, with ramicauls up to 2 cm long and leaves reaching 7 cm in length. This variation may be attributed to differences in climate and light exposure, as observed in several other species of the genus.
