Abstract

23. Menaethiops delagoae Barnard, 1955 (Fig. 4B) Menaethiops delagoae Barnard, 1955: 13, figs. 3G–I.— Guinot 1967a: 293 (list).— Serène 1968: 53 (list).— Kensley 1970: 103 (list); 1981: 40 (list).— Griffin 1974: 20, fig. 4B.— Griffin & Tranter 1986: 87 (key).— Ng et al. 2008: 101 (list).— Emmerson 2016c: 461 (list).— Bento & Paula 2018: 35 (list).— Muñoz et al. 2021: 52 (list). Material examined. RMNH. CRUS.D.58410, 2 males (7.0 × 12.0 mm, 5.5 × 6.5 mm), in front of Barreira Vermelha, fcn. X4211, 19 October 1986, leg. J.H.C. Walenkamp; RMNH. CRUS.D.58411, 1 male (8.0 × 13.0 mm), between Thalassodendron ciliatum, in front of Barreira Vermelha, fcn. X4072, 25 September 1984, leg. J.H.C. Walenkamp. Remarks. Not much is known of this rare epialtid crab. Menaethiops delagoae was named in the checklists of Emmerson (2016c) and Muñoz et al. (2021) for Mozambican waters, but there seem to be no recent observations of this species. Barnard (1955) provided adequate drawings and a description to compare the examined material to. The specimen has the long rostral horns figured by Barnard (1955: p. 14, fig. 3G) and the granules on the first male thoracic sternite. Distribution. Mozambique (Barnard 1955; Emmerson 2016c; Griffin 1974; Kensley 1970, 1981; Muñoz et al. 2021).
