Contributions towards a revision of Macrophthalmus (Crustacea: Brachyura) : VIII. A re-examination of the M. Telescopicus (Owen) complex; the status of M. Laevis A. Milne Edwards; and the Affinities of M. Holthuisi Serène
INTRODUCTION To date (1976), this author in his gradual revision of the ocypodid genus Macrophthalmus Latreille has described or redescribed thirty one valid extant species, noted three extinct species, and listed twenty seven other specific names as being synonyms (Barnes, 1966a, 1966b, 1967, 1968, 1970, 1971, 1973)• In this paper, he had hoped to complete the revision by considering the remaining thirteen described species, and by re-examining one species earlier reduced to a synonym. However, it has proved extremely difficult to trace material of some, and to examine material of other, of the species, particularly those known only from a holotype. Accordingly, rather than delay matters indefinitely, he has had to content himself with consideration of the following species: M. verreauxi H. Milne Edwards, 1848, M. laevis A. Milne Edwards, 1867, M. milloti Crosnier, 1965, M. ceratophorus Sakai, 1969, M. ressli Pretzmann, 1971, M. holthuisi Serène, 1973. It is hoped that an investigation of the remaining eight species (M. leptophthalmus (H. Milne Edwards, 1852), M. consobrinus Nobili, 1906, M. gastrodes Kemp, 1915, M. franchettii Maccagno, 1936, M. boteltobagoe Sakai, 1939, M. gallardoi Serène, 1971, M. philippinensis Serène, 1971 and M. vietnamensis Serène, 1971) can be completed in the not-too-distant future. THE MACROPHTHALMUS TELESCOPICUS COMPLEX Since the publication of Teseh's (1915) review of Macrophthalmus, most authors (including this one, e.g., Barnes, 1967, 1970) have regarded M. telescopicus (Owen), M. podophthalmus Souleyet and M. verreauxi H. Milne Edwards as synonyms; whilst in 1965 Crosnier described another species, M. milloti, which Barnes (1967) suggested was extremely closely related to,
