Pleurthallis quadricaudata Schltr. and P tetrachaeta Luer share a triangular-sagittate lip with a narrowly acute apex, while the apical lobe of the lip of P. tipuloides Luer Luer is narrowly triangular with a sharply acute apex. The lip of P. thoerleae is short and rounded, with an abruptly protruding apiculum." Luer 2012
