description: <i>Trizocarcinus dentatus</i> (Rathbun, 1893) (Figs. 44A–G; 46A–F) <i>Carcinoplax dentatus</i> Rathbun, 1893: 243 [Gulf of California]. <i>Trizocarcinus dentatus</i> Rathbun 1914a: 118, fig. 1, pl. 1; 1918: 18, fig. 3, pl. 1 [Gulf of California]. — Garth 1948: 52 [Ecuador]; 1960: 113. — Guinot 1969b: 518 [discussion], figs. 37, 44, 46, 48, 49 [holotype]; 1971: 1081 [in list]. — Chirichigno 1970: 61, fig. 151. — del Solar 1970: 44 [Perú]. — del Solar <i>et al</i>. 1970: 27 [Perú]. — Hendrickx 1990: 49 [Gulf of California]; 1992: 9 [in list]; 1993a: 314 [in list]; 1995: 139 [in list] [Pacific coast of Mexico]. — Lemaitre &amp; Álvarez-León 1992: 56 [in list]. — Ng <i>et al</i>. 2008: 78 [in list]. <b>Type material.</b> Male holotype (USNM 17462); 1 male paratype (USNM 123310). <b>Type locality.</b> Mexico, Gulf of California, Sonora, off Cabo Lobos, 54–137 m. <b>Material examined.</b> <i>Mexico.</i> Bahía de San Ignacio, Gulf of California, 30.03.1980: 1 male, 14.7 mm × 20.2 mm (MNHN-B20990). – Gulf of California, <i>Albatross</i>, stn. 3017, 29°54.5’N, 113°01.0’W, 104 m, 24.03, 1889: 1 pre-adult female, 10.0 mm × 12.4 mm (USNM 17463); stn. 3035, 1 pre-adult female, 7.3 mm × 8.7 mm (USNM 17464). – Roca Consag, Gulf of California, 31°7’N, 114°29’W 09.05.1982: 1 male, 15.3 mm × 20.3 mm (MNHN-B20987). <b>Diagnosis.</b> Dorsal, ventral surface of carapace granular (Fig. 44B, C, F, G). Granular stridulating ridge on pterygostomian region (Rathbun 1918: fig. 3). G1 apex exceptionally long (Fig. 46E). <b>Remarks.</b> <i>Trizocarcinus dentatus</i>, which is restricted to the Tropical Eastern Pacific region, shares with the Western Atlantic <i>T. tacitus</i> Chace, 1940, a carapace with curved anterolateral borders each armed with two teeth (Figs. 44A; 45A) as well as the other characters that define the genus <i>Trizocarcinus</i>. Its carapace, however, is granular in contrast to the smooth carapace of <i>T. tacitus</i>. The conspicuous, granular stridulating ridge along the pterygostomian region of <i>T. dentatus</i> (Rathbun 1918: fig. 3) is absent in <i>T. tacitus</i>, and the cheliped tomentum (Fig. 44D) is generally more conspicuous than that of <i>T. tacitus</i>. <b>Distribution.</b> Tropical Eastern Pacific region from the Gulf of California to northern Perú. Depth: 36– 126 m.
