03889534FFACFFF8FF41FE39FBF8FAAA.taxon	description	DESCRIPTION Body shape and proportions of males and females as described and depicted by Kiefer (1956), Gaviria (1989), and Dussart & Defaye (1995) (Figs 1 A, C; 3 A; 4 A). Mean length (n = 7) of females: 1.32 mm (1.30 - 1.33 mm), cephalothorax 0.97 mm long, 0.42 mm wide, with usual spiniform processes (Fig. 3 B). Rostrum strong, bifid (Fig. 3 C). Urosome 0.35 mm long (Fig. 2 B). Antennules 0.98 mm long. Genital somite 2 or 3 - segmented, 0.21 mm long, 0.13 mm wide, 59 % of urosome length. Urosome 26 % of total body length. Female genital operculum (Figs 2 C; 3 F) with wide, curved proximal plate, posterior end with strong, inwards curved lateral arms. Mean length (n = 6) of males: 1.09 mm (1.03 - 1.18 mm), cephalothorax 0.78 mm long, 0.33 mm wide. Left antennule 0.91 mm long. Urosome 0.31 mm, 28 % of total body length. Antennules female (Fig. 1 B) Relatively short, 25 - segmented, reaching posterior margin of fifth pedigerous somite or even posterior margin of anal somite in some specimens. Long setae on segments 3, 11, 14, 18, 21, 23 - 25. Setae on segments 16, 18, 21, 22 - 25 biserially plumose on distal 1 / 3. Appendages per segment as follows (Arabic numerals, segment; Arabic numerals between brackets, number of setae; ae, aesthetasc; sp, spine): 1 (1), 2 (3 + 1 ae), 3 (1 + 1 ae), 4 (1), 5 (1 + ae), 6 (1), 7 (1 + ae), 8 (2), 9 (1 + ae), 10 (2), 11 (1), 12 (1 + ae), 13 (1), 14 (1 + ae), 15 - 18 (1), 19 (ae), 20 (1), 21 (1), 22 (1 + ae), 23 (2), 24 (2), 25 (3). Antennules male (Figs 1 D; 4 E) 22 - segmented, left antennule as in female, but relatively shorter, reaching posterior margin of first urosomite. Right antennule broadened between segments 13 - 17. Appendages per segment as follows: 1 (1), 2 (2), 3 (1), 4 (1), 5 (1), 6 (1), 7 (1), 8 (1 + sp), 9 (3), 10 (1 + sp), 11 (1 + sp), 12 (2), 13 (1 + sp), 14 (2), 15 (2), 16 (2), 17 - 18 (0), 19 (1), 20 (2), 21 (1), 22 (4). Large spine-like processes on segments 8, 10, 11, and 13. Process on segment 11 largest, reaching distal margin of segment 13 (Figs 1 E; 4 E). Low, broad-based spine on segments 12, 15, and 16, spine on 16 slightly larger than that on 15. Fifth legs female and male (Figs 2 A, D-F; 3 D, E; 4 B-D). In general, as described and depicted by Gaviria (1989), Kiefer (1956), Wilson & Yeatman (1959), and Dussart & Defaye (1995). In the female, the large spine on the third exopodal segment of the fifth leg is relatively longer in our specimens than in other descriptive works considered. Moreover, there are differences in the length ratios of the fifth female leg and in the number of urosomites (Table 1). In the male, other slight differences were noted when our specimens were compared with published illustrations and descriptions (Table 1).	en	Gutiérrez-Aguirre, Martha Angélica, Suárez-Morales, Eduardo (2000): New extension range of the diaptomid copepod Prionodiaptomus colombiensis Thiébaud, 1912 (Copepoda, Calanoida) with complementary description of this species.
