Etymology
The species is dedicated to Prof. M. Lamotte, an ecologist who collected many spiders in the Nimba Mts.

Differential diagnosis
The male palp is similar to that of P. spiniger sp. nov. in having a sinusoid anterior lobe of the bulb, but may be recognized by the strongly sclerotized keel on the prolateral edge of this lobe and the absence of a spine at the base (compare Fig. 1A–C with Fig. 13A–C). The female slightly resembles those of P. securis sp. nov. and P. spiniger sp. nov. They share an epigyne in which the distance between the lateral edges of the atria is smaller than the distance between the lateral edges of the spermathecae. However, P. lamottei sp. nov. may be distinguished by the atria, which are cup-shaped (narrower in the other species, compare Fig. 2A–C with Figs. 12A–B and 15A–C). Pochytoides lamottei sp. nov. also differs from P. spiniger sp. nov. by the presence of epigynal pockets and from P. securis sp. nov. by clearly shorter seminal ducts.
