Diagnosis. Medium-sized species (60–70 mm carapace length). Carapace pyriform; dorsal surface gently convex; uniformly covered with granules and short spines, those on posterior part of branchial and intestinal regions spiniform ( Fig. 6C, D View Fig ). Pseudorostral spines long, straight, strongly diverging ( Figs. 6C, D View Fig , 36F View Fig ). Supraorbital eave relatively narrow, antorbital spine sharp, gently curved upwards; intercalated spine stout, short, touching postorbital spine basally; postorbital spine largest, long, sharp; hepatic spine sharp with 1 short accessory spines basally ( Figs. 6C, D View Fig , 36F View Fig ). Lateral margin of carapace with 3 strong spines, second longest, and several small sharp granules and short spines ( Fig. 6C, D View Fig ). On median row 5 spines: 3 gastric, 1 cardiac, 1 intestinal ( Fig. 6C, D View Fig ). Branchial region with 1 strong spine; posterior carapace margin with 2 long spines ( Fig. 6C, D View Fig ). Basal antennal article very broad with 2 long distal spines; outer margin with proximal lobiform tooth, appressed on suborbital tooth ( Fig. 39E, F View Fig ). Ischium of third maxilliped rectangular, much longer than broad ( Fig. 43G, H View Fig ). Carpus of cheliped with distinct tubercles and granules ( Fig. 53G, H View Fig ). Ambulatory merus with strong subvertical subdistal spine on dorsal margin ( Fig. 6F View Fig ); dactylus covered with short setae ( Fig. 55D View Fig ). G1 long, gently curved; distal part gently curved upwards ( Fig. 7R–T View Fig ).

Remarks. Neomaja goltziana was originally described from Portuguese waters (d’Oliviera, 1889). Although the year of publication is usually cited as 1888, volume 36 (where the paper was published) is dated July 1888 to June 1889, and the year “1889” was printed at the bottom of title page of the paper.

Neomaja goltziana is superficially similar to Paramaya spinigera , especially with regards to its spiny carapace and the ambulatory meri possessing a strong distal spine on the dorsal margin. Bouvier (1940: 323) comments that “une forte épine au bout distal du mérus des pattes ambulatoires”. However, as discussed under the genus, there are many substantial differences between the two species at the generic level.

Neomaja goltziana View in CoL was described from Portuguese waters. Manning & Holthuis (1981: 307) reported a distribution from Mediterranean to Congo, between 15 to 200 m.
