A review of the hyperiidean amphipod superfamily Lanceoloidea Bowman & Gruner, 1973 (Crustacea: Amphipoda: Hyperiidea) Author Zeidler, Wolfgang text Zootaxa 2009 2009-02-04 2000 1 117 journal article 1175­5334 Lanceola falsa Vinogradov ( Fig. 17 ) Lanceola falsa Vinogradov, 1970: 391–393 , fig 5. Vinogradov et al . 1982: 60–61 , fig. 10. Type material. This species was described from two sexually mature females, with body length of 22 and 24 mm , caught in the Kurile-Kamchatka region of the North-west Pacific ; Vityaz Stn. 5606 [ 46º10’N 153º13’E ; 0–4000 m ] and Vityaz Stn. 5612 [45º23’– 45º34’N 153º04’– 153º48’E ; 0–5850 m ]. The female of length 22 mm is described and figured by Vinogradov (1970) and is in the ZMMU (Mb–1044), on microscope slides . Diagnosis. According to Vinogradov (1970) . Only known from the two female specimens as detailed above. Habitus like L. sayana . Head with small, indistinct, hooked rostrum. Eyes small, reniform, without crystalline cones. Antennae 1 relatively short; terminal article slightly longer than preceding two combined. Antennae 2 length about 1.5x A1. Pereopod 3 similar to P4; basis length about twice merus; carpus slightly longer than merus; propodus slightly longer than carpus; dactylus short, length about 0.2x propodus. Pereopods 5–7 with stout articles with longitudinal ridges; the dactyls are stout and non-retractile and the propodus is without spoon-shaped formation. Pereopod 5 similar in length to P4; basis length about 1.8x merus; carpus slightly longer than merus; propodus length 1.2x carpus; dactylus short, stout, slightly curved. Pereopod 6; length 1.2x P5; basis length 1.5x merus; carpus length 1.4x merus; propodus length 1.2x carpus; dactylus as for P5. Pereopod 7; length 0.6x P6; basis length slightly more than twice merus; carpus length 1.7x merus; propodus length 1.3x carpus; dactylus as for P5. Uropoda with relatively broad rami, especially U3. Telson rounded; length 0.7x peduncle of U3. Colour of living specimens not recorded. Remarks. I have not seen any specimens of this species but accept its validity based on the observations of Vinogradov (1970) . This species is distinguished from all of its congeners by the non-retractile dactyls of pereopods 5–7, and in this character is atypical of the genus Lanceola . However, its removal from Lanceola is not warranted at this stage because it superficially resembles other species of Lanceola , such as L. sayana and L. pacifica . The loss or reduction of retractile and hooded dactyls is also seen in pereopod 5 of L. sphaerica , L. chelifera and L. gruneri sp. nov. , but in these species retractile and hooded dactyls are maintained for pereopods 6 & 7. Distribution. Only known from the Kurile-Kamchatka region of the Pacific Ocean, from two specimens as detailed above.
