Species Mormonilla phasma - Plate 1 of morphological figuresissued from : K.H. Cho, W.-S. Kim & W. Lee in Korean J. Environ. Biol., 2007, 25 (1). [p.78, Table 1].
The characters of Mormonilla phasma female compared with Boxshall's (1979, 1985) and Boxshall & Huys' specimens.
Nota: Specimens collected in the southern Hawaiian Islands are similar to the Huys & Boxshall's descriptions in the following features: A1 3-segmented; Mx2 5-segmented with total 4 endites; Mxp 3-segmented; P2-P4 with 2-segmented exopods and 1-segmented endopod; urosome 4-segmented with a genital complex formed by fusion of the genital somite and the 1st abdominal somite. However, morphological characteristics of A2, Md and P1 were slightly different from Boxshall (1979, 1985) and Huys & Boxshall (1991). In the Hawaiian specimens the authors have found morphological anomalies in endopodal segments of the P1; P2-P3 shows various number of serration in inner margin of the 1st exopodal segment (the number of serration bears 8 to 15 in P2 and 7 to 9 in P3). These variations seem to be within the range of intra-specific variation, but the male is lacking here.

According to Ivanenko & Defaye (2006, p.724) further re-examination of mormonillids from the type locality (tropical part of the Pacific Ocean: Giesbrecht, 1891 and 1892) and comparisons with mormonillids from the northeastern Atlantic are necessary to confirm the identity of copepods from the two oceans, currently referred to M. phasma Giesbrecht, 1891.
First occurrence in Chilean waters by Hidalgo & al. (2010).
