TypesSyntype: ZMH R04376 (formerly no. 339), Formerly there were 2 syntypes. 
DiagnosisDiagnosis: A species of Toxicodryas restricted to West Africa, west of the Niger Delta, defined by the following combination of characters: maximum SVL < 1 meter (vs. maximum SVL > 1 meter in T. blandingii and T. vexator sp. nov.), DSRN 19–21 (vs. 23–25 in T. blandingii and 23–29 in T. vexator sp. nov.), DSRM 19–21 (vs. 21–25 in T. blandingii and T. vexator sp. nov.); cloacal plate undivided (vs. usually divided in T. blandingii, and divided or undivided in T. vexator sp. nov.); both sexes brown to pink with darker cross-bars that often enclose a whitish spot, and the dorsum and venter sprinkled with fine dark brown or black spots (vs. adult males glossy or velvety black with a yellow venter, and adult females light brown, gray, or yellowish-brown with light-brown or cream cross-bars on the flanks, with yellowish-brown venters in T. blandingii and T. vexator sp. nov.); hemipenis relatively long with long spines mid-way along the shaft that decrease in size towards the apex and base, with a domed apex (vs. hemipenis relatively short and massive [i.e., broad], proximal third covered with spines, distal two-thirds dimpled with a flattened apex in T. blandingii and T. vexator sp. nov.) (GREENBAUM et al. 2021).

CommentDistribution: Has been reported from Sao Tome but records neen confirmation (SCHÄTTI & LOUMONT 1992); recent investigations show it actually doesn’t occur there (Ceríaco et al. 2018). The type locality has also been given as Sao Tomé [Is., West Africa], but that appears to be incorrect (Greenbaum et al. 2021,Loveridge 1958: 269).

Habitat: fully arboreal (Harrington et al. 2018).
