The addition of the new specimen figured here does not warrant a redescription of the species as only a partial thorax is present. At least six prothoracic segments and thirty-six opisthothoracic segments are visible in this specimen. The end of a spine found most abaxially to the right on the specimen is likely part of a macropleural T3 spine. The length of the prothoracic segments are long, some are longer than the length of the entire opisthothorax.
