Remarks. Daldorfia horrida is one of the only two species in the Parthenopidae MacLeay, 1838 reported from Mozambican waters (Emmerson 2016c; Muñoz et al. 2021). It is easy to distinguish from the other parthenopid present in Mozambican waters, Enoplolambrus carenatus (H. Milne-Edwards, 1834). On D. horrida the fingers of the chelipeds are slightly incurved, while on E. carenatus the fingers are strongly incurved (Barnard 1950), pointed and slightly overlapping when closed. Also, on D. horrida the walking legs are strongly tuberculate, while on E. carenatus, they possess spaced, feeble denticles (Barnard 1950). The examined specimens match well with the very extensive description in the review of the Daldorfiinae Ng & Rodríguez, 1986 by Tan & Ng (2007a) and with the comparative material. Distribution.
