Lasiocyano Sazimai - Brazilian Blue Tarantula

Introduction

Lasiocyano sazimai, formerly known as Pterinopelma sazimai, is a striking New World terrestrial tarantula with iridescent blue coloration. Endemic to Brazil, particularly the Bahia, Minas Gerais, and Chapada Diamantina regions, this species thrives in rocky, dry environments. While stunning, this tarantula is best suited for intermediate keepers due to its skittish nature, moderate speed, and occasional defensive behavior. If you’re looking for a visually impressive species that displays bold colors with a manageable temperament, L. sazimai is an excellent choice.

Taxonomy & Name Change

In 2023, taxonomic revisions led to Pterinopelma sazimai being reassigned to a newly established genus, Lasiocyano, based on molecular and morphological studies. The name Lasiocyano is derived from the Greek words "lasio-" (meaning hairy) and "cyano-" (meaning blue), referring to the species' distinctive blue iridescence and dense setae. The revision was part of an effort to clarify the phylogenetic relationships within the Theraphosidae family, as prior classifications placed Pterinopelma species under a broader category that was not fully supported by genetic evidence.

What Makes Lasiocyano sazimai Special?

This species stands out for its vibrant iridescent blue hues, which are most visible under bright lighting or after a fresh molt. The contrast between the metallic blues, deep blacks, and reddish-brown setae makes L. sazimai one of the most visually impressive tarantulas in the hobby. Unlike some other New World species, it lacks extreme defensiveness but can still be skittish and quick when startled.
