Holotype , ovigerous female, 2.2 mm , USNM 107585. [Not examined]. Type locality. Immediately south of cannery, Bahia de San Quintin, Baja California, Mexico , eastern North Pacific Ocean, (approx. 30°30'N , 116°00'W ), 2–3 m depth. Diagnosis . Head lateral cephalic lobe rounded. Maxilla 1 palp article 2 with 1 seta. Maxilliped inner plate without robust setae. Coxae 1 to 3 ventral margin without fine setae. Gnathopod 1 basis anterior margin smooth, not cuspidate. Pereopod 3 carpus subtriangular, posterior margin as long as free proximal margin of propodus, posteroproximal margin slightly produced; propodus length 1.7 × width, posteroproximal margin not produced, palm obtuse, weakly convex. Epimeron 3 posteroventral corner subquadrate. Uropod 3 outer ramus article 2 length 3 × width; inner ramus shorter than article 1 of outer ramus. Telson about as long as broad, length 1 × breadth. Description of holotype . Head lateral cephalic lobe rounded, ventral margin straight. Antenna 1 peduncular article 3 hidden in medial view; accessory flagellum 4-articulate; primary flagellum 5-articulate. Mandible incisor subquadrate, margin near smooth; palp attached about midway, just proximal to molar, palp article 2 length 1.4 × article 3. Maxilla 1 inner plate without apical setae; outer plate with 7 setal teeth. Maxilla 2 inner plate apically rounded, much shorter than outer plate. Maxilliped inner plate apically cuspidate, without robust setae; outer plate margin cuspidate with 4 embedded robust setae; palp article 4 slender, claw-like, unguis present. Pereon. Coxae 1–3 ventral margin without fine setae. Gnathopod 1 simple; basis anterior margin smooth, not cuspidate; carpus length 1.1 × width, 0.8 × propodus length; dactylus posterior margin smooth. Gnathopod 2 minutely chelate. Pereopod 3 chelate; merus length 1.3 × width, subequal to carpus length; carpus subtriangular, posterior margin as long as free proximal margin of propodus, posteroproximal margin slightly produced; propodus length 1.7 × width, posteroproximal margin not produced, palm obtuse, weakly convex. Pereopods 5–7 basis posterior margin expanded, convex; merus posterior margin expanded. FIGURE 21. Ensayara ramonella J.L.

Epimera 2–3 posteroventral corner subquadrate. Uropods 1–2 peduncle with 1 apical robust seta; outer ramus with 1 lateral robust setae; inner ramus without robust setae. Uropod 3 peduncle without robust setae; inner ramus shorter than article 1 of outer ramus, lined with short robust setae; outer ramus 2-articulate, article 2 length 3.5 × width. Telson about as long as broad, length 1 × width. Distribution. Mexico : Baja California ( Barnard 1964 ).
