Isaac in Mitt. Zool. Mus., Berlin, 1974, 50 (1). [p.134, Fig.3]. As Strilloma longa. Female (from Island of Dry Tortugas, Florida): A-B, habitus (lateral and dorsal, respectively); C, abdomen (dorsal); D, P4 (omitting the base of the basipodite); E, right A1 (ventral); F, left A1 (lateral); G, P5. A-B: same scale; E-F, G same scale as D.

 Issued from : E. Suarez-Morales & R. Gasca in Zool. Studies, 2004, 43 (2). [p.294, Figs.1-5] Female (holotype): 1-2, habitus (ventral and dorsal; 3, head (dorsal); 4, head (ventral), showing 3rd pair of nipple-like protuberances (arro); 5, head (lateral; A1 cut short). Nota: - Cephalothorax accounting for 66% of total body length (measured from anterior end of cephalic somite to posterior margin of anal somite). - Oral papilla protuberant, located close to anteriormost part of body, midventrally 0.13 of way back along cephalothorax. - Nauplius eye present, weakly developed, ocelli rematively small, widely separated, slightly pigmented, with oblong shape, eyes separated by almost 5 eye diameters. - A1 relatively long, 4-segmented (intersegmental divisions well defined), slender, slightly longer than 20% of total body length, and about 1/3 of length of cephalothorax.

 Issued from : E. Suarez-Morales & R. Gasca in Zool. Studies, 2004, 43 (2). [p.295, Figs.6-11] Female (holotype): 6, habitus (lateral; antennular setae omitted); 7, left A1 (dorsal); 8, left A1 (ventral); 9, 1st free abdominal, anal somite, and caudal rami with setae (lateral pair of caudal setae cut short); 10, 5th pedigerous somite, genital double-somite, 1st free abdominal somite, and anal somite plus P5 (setae of right leg cut short), and bases of ovigerous spines (ventral); 11, same (lateral). Nota: P5 moderately long, 1-segmented, fused medially, each represented by a cylindrical rod armed with 4 long, lightly plumose setae, all subequal in length and breadth, innermost slightly longer. Setae reaching distal margin of anal somite; left ramus of P5 partially broken and folded upwards in this specimen.

[p.296, Figs.12-19] Female (holotype): 12, P1 (anterior), protopods greatly foreshortened due to viewing angle; 13, P2 (anterior), same protopods view; 14, P4 (anterior), same protopods view; 15, genital double-somite with base of ovigerous spine, showing incomplete suture (arrow); 16, 4th pedigerous somite with protopods of legs, showing broken ventrakl surface forming protuberance artifact; 17, urosome (dorsal); 18, base of ocigerous spines; 19, distal part of ovigerous spines with attached eggs.

 Issued from : E. Suarez-Morales & R. Gasca in Zool. Studies, 2004, 43 (2). [p.298, Table 1] Female (holotype): Characteristic of morphological features in M. longa. Distal antennular segment comprising over 50% of A1 length and 4 setae on P5. A1: antennule; TBL: total body length. Compare with M. careli and M. careloides.
