[1][4] The specific name wendyae honours Wendy Clarke, the describer's wife.

The ventral surfaces are mostly light with scattered minute black specks, but the interfemoral region has a large chocolate-brown mark beset with white tubercles.

[3] Nectophrynoides wendyae occurs in montane rainforest at elevations of 1,500–1,650 m (4,920–5,410 ft) above sea level.

[3] While quite abundant in one tiny part of its range, Nectophrynoides wendyae is listed as critically endangered due to its very restricted distribution (estimated extent of occurrence no more than 15 km2) and ongoing habitat deterioration and loss.

It occurs in the Udzungwa Scarp Forest Reserve, but the area is not well protected.
