Species Monstrilla elongata - Plate 1 of morphological figuresissued from : E. Suarez-Morales in Proc. Biol. Soc. Washington, 1994, 107 (2). [p.263, Fig.1].
Female (from off Puerto Morelos, Yucatan): A-B, habitus (dorsal and lateral, respectively); C, right A1 (dorsal); D, left A1 (dorsal); E, forehead (dorsal); F, urosome (ventral); G, P5 (ventral view).
Nota: cephalic segment long and slender, almost 0.65 of total body length. Oral papilla located 0.43 of way back along cephalic segment. Eyes absent. A1 5-segmented (2-5 partially fused); ratio of length of 1st segment and remainder 14:86 = 100; A1 0.24 of total body length. Head and 1st pedigerous somite fused. P5 1-segmented with broad single lobe bearing 2 setae, outer seta slightly longer than inner. Urosome consisting of 5th pedigerous somite, genital double somite and 2 free abdominal somites; length ratio of these 4 segments 39.6: 33.3:14.6:12.5 = 100.


Species Monstrilla elongata - Plate 2 of morphological figuresissued from : E. Suarez-Morales in Proc. Biol. Soc. Washington, 1994, 107 (2). [p.265, Fig.2]. Female: H, urosome (lateral); I, genital segment with ovigerous structures, and caudal rami (ventral); J, P2; K, P3; L, P1.
Nota: Genital complex with annulated ovigerous structures. Caudal rami 2.3 times longer than wide, bearing 5 setae.

Distribution map of Monstrilla elongata by geographical zones
Loc:
Mexico (Reef lagoon off Puerto Morelos, Yucatan), Philippines (Caldera Bay)
N: 2
Lg.:
(742) F: 4,20; (801) F: 3,4-2,8 [furca exclue]; (873) F: 1,6-3,3; M: 2,1-3; 3,5-3,68; {F: 1,60-4,20}
Rem.: In water column; over Thalassia testudinum beds.
For Suarez-Morales (2000 b, p.686) the record of M. elongata in the Philippines represents an important range extension for this species, previously known only from the Mexican Caribbean Sea.
