跟據1988的論文< Land hermit crabs from the Ryukyus, Japan, with a Description of a New Species from the Philippines (Crustacea, Decapoda, Coenobitidae) >,在菲律賓(宿霧島)發現的Coenobita pseudorugosus和灰白陸寄居蟹(Coenobita rugosus)有密切關係,前甲長可達12mm。
跟據2002年的論文< Ecology of subtropical hermit crabs in SW Madagascar: Refuge-use and dynamic niche overlap >,Coenobita pseudorugosus棲息於馬達加斯加西南部,半荒漠草原邊緣的海岸,研究內容很清楚分析Coenobita pseudorugosus和Coenobita rugosus的分佈和習性。
跟據2002年的論文< Temporospatial constraints in resources available to and used by hermit crabs: tests of models >,研究內容很清楚分析棲息於馬達加斯加西南部的Coenobita pseudorugosus和Coenobita rugosus與螺殼的關係。
Tirmizi and Siddiqui (1982. The Marine Fauna of Pakistan) 的詳細報告中,有介紹過巴基斯坦的寄居蟹類,Asakura看過被鑑定過的「Coenobita scaevola」的繪圖,其雄性生殖器形狀和Coenobita pseudorugosus相同。Asakura有直接觀察過紅海產的Coenobita scaevola(標本),認為Tirmizi and Siddiqui繪圖的眼睛形狀比起Coenobita scaevola,更加接近Coenobita pseudorugosus。Asakura認為巴基斯坦報告中的Coenobita scaevola實際很大可能是Coenobita pseudorugosus。
