Summary: | Photis inornatus sp. nov. (Figs 1–3) Type material. HOLOTYPE, Holotype female, 3.2 mm (MNHN-IU- 2009 - 585), Paratypes: 4 males, 12 females, same data as holotype (MNHN-IU- 2009 - 586). Type locality. Bay of Concarneau (47 ° 44 ' 16.3 "N; 3 ° 53 ' 34.7 "W and 47 ° 48 ' 32.1 "N; 3 ° 55 ' 31.8 "W) Etymology. Latin inornata, meaning unornamented, referring to the uniform palms of the gnathopods in both sexes. Description. Based on Paratype male MNHN-IU- 2009 - 586, 3.4 mm. Head. Head with strongly forward produced, rounded eye lobe. Eye, black, composed of many ommatidea, situated fully in eye lobe. Antenna 1 almost equal to body length; peduncular article 3 longer than 2; flagellum longer than peduncle, composed of about 13 flagellar articles. Antenna 2 longer than 1; peduncular articles 4 and 5 subequal in length; flagellum longer than peduncle, with about 20 articles. Labrum anterior margin weakly setiferous. Mandible with strong molar, palp 3 -articulate, article 1 very short, article 2 much longer than 3, article 3 subsymmetrical, spatulate, with long distal setae. Maxilla 1 inner plate small, subtriangular, asetiferous, palp 2 - articulate, article 2 extending well beyond outer plate. Maxilla 2 inner plate with oblique setal row. Labium mandibular processes rounded. Maxilliped outer plate posterior margin scalloped, palp very long, article 2 elongate, extending well beyond distal margin of outer plate. Pereon. Gnathopod 1 coxa unproduced, rounded; basis moderately stout, about two and a half times as long as broad, with 6–8 long setae on the posterior margin; carpus and propodus subequal; propodus palm evenly rounded delineated by stout robust seta, but evenly continuous with posterior margin; dactylus strong, overlapping position of robust seta. Gnathopod 2 similar to gnathopod 1, basis stout, length less than twice breadth; carpus a little shorter than propodus; propodus subovoid, palm scarcely delineated, delimited by robust seta; dactylus strong, overlapping position of robust seta. Pereopods 3–4 stout, ... |
