Pseudoparonella (Oceaniella) griseocoerulea Yoshii, 1989

Type locality. New Caledonia.

Material examined. Nine females on slides and 24 in alcohol, New Caledonia: Rivière Bleue, alt. 160 m, Malaise trap, 25.xi‒8.xii.1986 and 26.iii‒9.iv.1987, L. Bonnet de Larbogne, J. Chazeau and S. Tillier leg. (# ρ6(25)ε9, ρ6(25)ε7, ρ6(20)ε7). Four specimens on slides and 5 in alcohol in NJAU and others in MNHN.

Remarks. Colour pattern species, Ps. bicincta , Ps. najtae , Ps. shibatai , and Ps. griseocoerulea from New Caledonia, share almost the same morphological features except colour pattern. However, intermediate colour patterns in a single population of Ps. griseocoerulea were found in this study which included pale and slightly pigmented individuals. The pale forms are identical with Ps. shibatai in colour, slightly differing from it in having 12 central macrochaetae on Th. II (15 in the latter) and 1 lateral macrochaetae on Abd. I (2 in the latter). It is not clear whether these minor chaetotaxic differences are interspecific or intraspecific characters.
