Ref.:
Brodsky, 1950 (1967) (p.388, figs.F, Rem.)
Species Centraugaptilus macrodus - Plate 1 of morphological figuresissued from : C.O. Esterly in Univ. Calif. Publs Zool., 1911, 6 (14). [Pl.27, Fig.18]. As Augaptilus macrodus.
Female (from San Diego Region): 18, habitus (lateral).

Female: 44, last thoracic segment and urosome.
Nota: The last thoracic segment shows a peculiar indentation or bay in the posterior border. Genital segment about as long as the 2nd and 3rd together, the 2nd half as long as the 3rd


Species Centraugaptilus macrodus - Plate 3 of morphological figuresissued from : C.O. Esterly in Univ. Calif. Publs Zool., 1911, 6 (14). [Pl.30, Figs.72, 74]. As Augaptilus macrodus.
Female: 72, A2 (endopod is at the left figure); 74, Md (biting edge).
Nota: Exopod of A2 longer than the endopod


Species Centraugaptilus macrodus - Plate 4 of morphological figuresissued from : C.O. Esterly in Univ. Calif. Publs Zool., 1911, 6 (14). [Pl.31, Fig.87]. As Augaptilus macrodus.
Female: 87, P1.


Species Centraugaptilus macrodus - Plate 5 of morphological figuresissued from : C.O. Esterly in Univ. Calif. Publs Zool., 1911, 6 (14). [Pl.32, Fig.112]. As Augaptilus macrodus.
Female: 112, exopo of P5.
Nota: The exopod and endopod of legs are 3-segmented, but the 3rd segment of endopod of P3 has 8 bristles instead of 6 as in that segment of P1, P2 and P4

Distribution map of Centraugaptilus macrodus by geographical zones
Loc:
NE Pacif. (California: off San Diego)
N: 1
Lg.:
(143) F: 5,31; {F: 5,31}
