Bulbophyllum parex is morphologically closest to Bulbophyllum bidentatum (Barb.Rodr.) Cogn., from which it differs in having lanceolate petals with a ciliate margin (vs. ovate-lanceolate petals with a lacerate-ciliate margin), the labellum with slightly ciliate lateral lobes (vs. to entire lateral lobes), and the middle lobe oblong-elliptic (vs. linear-ligulate).

Etymology: The specific epithet, parex, is given in gratitude to Parex Resources company, for their financial and logistic support in the process of studying and publishing the new species.
