Seems the Nhandu vulpines is the same as the Nhandu tripepii.

Nagahama, R.H., Fukushima, C.S. & Rogerio Bertani. 2009. Nhandu tripepii is a senior synonym of Nhandu vulpinus (Araneae: Theraphosidae). ZOOLOGIA. 26(3): 578-580.
Abstract:
The holotype of Eurypelma tripepii Dresco, 1984 from the state of Para, Brazil, is revised and illustrated. It's palpal bulb and tibial apophysis are similar in shape to species of Nhandu Lucas, 1983. Therefore, the species is transferred to the genus Nhandu, establishing the new combination Nhandu tripepii (Dresco, 1984) comb. nov., which is considered a senior synonym of Nhandu vulpinus (Schmidt, 1998) syn. nov. The protuberances present on the holotype's chelicerae are here considered a morphological anomaly.

Oh, the common name is the same for the two.
