Family Epialtidae Macleay, 1838

Remarks. Lee et al. (2019) reported on a large collection of epialtid crabs from Papua New Guinea and adjacent areas. The present study found further specimens of the following species previously reported from Papua New Guinea: Crocydocinus ewok Lee, Richer de Forges & Ng, 2019 ; Samadinia ahyongi (McLay, 2009) ; S. boucheti ( Richer de Forges & Ng, 2013) and Tunepugettia corbariae Lee, Richer de Forges & Ng, 2019 . In this paper, we only treat a few species. The taxonomy of Griffinia lappacea ( Rathbun, 1918) , which had earlier been misidentified as G. takedai Richer de Forges & Ng 2012 , is reappraised and new characters used to separate these two allied species. Variation in G. lappacea is also discussed. Griffinia gilloloensis ( Rathbun, 1916) and Oxypleurodon luzonicum ( Rathbun, 1916) are also recorded from Papua New Guinea. Specimens of Hyastenus ? borradailei (Rathbun, 1907) are now reported from Papua New Guinea for the first time and aspects of its taxonomy discussed.
