Among the sterninotata - group, males of P. adamsoni are most similar to P. yoshidai by the conductor extending into a pointed, sclerotised distal part (Figs 1 C, D, 3 A, B) but can be distinguished by shorter embolus, not coiled at the tip (vs longer, tip with horizontal coiling in P. yoshidai) (Huang et al. 2025: fig. 10 A – C). Females are most similar to P. harapan sp. nov. by the inflated, sclerotised distal part of copulatory ducts but can be distinguished by the rectangular initial part of copulatory ducts (Figs 2 C, D, 3 C, D) (vs copulatory ducts arc-shaped in P. harapan Dhiya’ulhaq, sp. nov.)

Females are most similar to P. debu sp. Nov. by the slightly bent copulatory ducts, but can be distinguished by the atrium slightly larger than spermathecae (Zhu 1998, fig. 95 B, C) (vs distinctly smaller atrium in comparison to the spermathecae in P. debu Dhiya’ulhaq, sp. nov.) (Figs 5 C, D, 6 C, D).	en	Dhiya’ulhaq, Naufal Urfi, Buchori, Damayanti, Hidayat, Purnama, Scheu, Stefan, Drescher, Jochen (2025): Two new species and three new records of the cobweb spider Platnickina (Araneae, Theridiidae) from Sumatra.
