Distribution map of Conaea hispida by geographical zones
Species Conaea hispida - Distribution map 3issued from : G.A. Heron & B.W. Frost in Proc. Biol. Soc. Washington, 2000, 113 (4). [p.1061, Fig.25].
Locality records for selected species of Conaea.
Records include previously published personal observations and data presented in this study (p.1023, Table 3).
Loc:
Antarct. (SW Pacif.), Station 'P', NE Pacif., ? off NE Cape Verde Is.
N: 3
Lg.:
(679) F: 0,7-0,54; (680) F: 0,56; M: 0,55; {F: 0,54-0,70; M: 0,55}
Rem.: Sampling depth (Antarct.) : 1000-2000 m. 3980-3960 m (NE Cape Verde Is.).
For Malt (1982, p.188) the species identified from NE Heron & Bradford-Grieve (1995, p.46) do not view the form described by Malt (1982) as a synonym. Heron & Frost (2000) do view it as a synonym.
