Paralysianopsis Schellenberg 1931

Description

Paralysianopsis Schellenberg, 1931

Paralysianopsis Schellenberg, 1931: 7.—J.L. Barnard, 1969: 356.— Lowry & Stoddart, 1984: 103.— Barnard & Karaman, 1991:

513.— Lowry & Stoddart, 1995b: 102. Austronisimus K.H. Barnard, 1931: 425 (type species = Austronisimus rhinoceros K. H. Barnard, 1931). Rhinolabia Ruffo, 1971: 103 (type species = Rhinolabia parthenopeia Ruffo, 1971).— Diviacco & Ruffo, 1989: 541.— Barnard & Karaman, 1991: 525.—Lowry & Stoddart, 1995: 116.

Type species. Paralysianopsis odhneri Schellenberg, 1931, monotypy.

Included species. Paralysianopsis includes 12 species: P. capricornia sp. nov.; P. dandenong sp. nov.; P. elliotti (Lowry & Stoddart, 1995b) comb. nov.; P. jebbi (Lowry & Stoddart, 1995b); P. mauritiensis Ledoyer, 1978; P. mazamoz Lowry & Stoddart, 1995; P. odhneri Schellenberg, 1931; P. padoz Lowry & Stoddart, 1995b; P. paeowai (Lowry & Stoddart, 1995b) comb. nov.; P. parthenopeia (Ruffo, 1971) comb. nov.; P. pomona sp. nov.; P. ruffoi sp. nov.

Diagnostic description. Antenna 1 accessory flagellum not forming operculum. Antenna 2 flagellum article 3–5 slender, brush setae present or absent. Labrum with epistome and upper lip fused or weakly separate. Mandibular incisor curved; molar a reduced column with reduced triturating surface or a flap with or without setae, with vestigial distal triturating patch; palp attached midway to slightly distally. Maxilla 1 ST-7 apically cuspidate; ST-D slender, apically cuspidate; palp distal margin with robust setae along entire or part of margin, or robust setae vestigial or absent. Maxilliped outer plate apical robust setae vestigial. Gnathopod 1 weakly to strongly subchelate; coxa large, nearly as long as coxa 2, not tapering; carpus slightly longer than propodus; propodus palm acute, straight. Pereopod 4 coxa with posteroventral lobe. Uropod 2 inner ramus constricted. Uropod 3 rami without plumose setae; inner ramus slender, lanceolate, 2-articulate, article 2 as long as or longer than article 1. Telson entire.

Remarks. The only character separating Paralysianopsis and Rhinolabia has been the well-developed apical robust setae on the palp of maxilla 1, present in Paralysianopsis (setae absent in Rhinolabia, but with a strong medially serrate margin). In P. pomona sp. nov. the medially serrate apical margin persists along with a set of lateral robust setae. In P. mazamoz the medial serrate margin is well developed and the robust setae are vestigial and in species such as P. paeowai there is only a remnant of the serrate medial margin and no robust setae. This is a gradational character which does not separate the genera.

Paralysianopsis incerta (Ledoyer, 1986) was transferred to Glorieusella Kilgallen & Lowry, 2014.
