Dromidiopsis indica (Gray, 1831) n. comb.

Female 59 × 58 mm, Nhatrang, McLay det. Lauridromia indica (MNHN-B 12758) (not dissected).

In the revision of McLay (1993) Dromia indica Gray, 1831 was assigned to Lauridromia McLay, 1993 , and the same way was followed later with a detailed description based on an abundant material ( McLay 2001c: 823). But this species does not conform to the two other species of the genus, L. intermedia (Laurie, 1906) , the type species, and L. dehaani (Rathbun, 1923) . D. indica must be referred to Dromidiopsis (see Guinot & Tavares 2003: 61) because of the following characters: abdominal segments 5 and 6 almost totally fused (a character shared by Dromidiopsis and Lauridromia ); external borders of abdominal segment 6 deeply excavated and thickened on the edges; telson long and ovate; male uropods oriented obliquely; anterior margin of sternite 4 bluntly truncate; female sternal sutures 7/8 gradually convergent, then getting abruptly close to each other and remaining parallel along the distal half of their lengths; spermathecal apertures located just between the P1, together at the summit of two coalescent tubercles; P4 with one distal propodal spine opposing the dactylus and, additionally, presence of two small outer propodal spines concealed by the setae (not signaled in the diagnosis given by Guinot & Tavares 2003); P5 with two unequal distal propodal spines opposing the dactylus, one outer propodal spine and one outer dactylus spine. In fact, Dromidiopsis and Lauridromia distinguish only by a very few characters, and the differences between D. intermedia (Gray, 1831) n. comb. and the other species of Dromidiopsis need to be re-evaluated (Guinot unpubl. data).

Lauridromia indica has the two sheets of the phragma 7/8 not completely joined; traces of sperm in the space between the sheets are visible on both sides of the specimen.
