Comments

More details of the description can be found here.

Species of the celetaria-group are characterized by:

  1. Head photophores:
    1. Type 1b pattern on head.
    2. Basal Row of head with 9 or 10 photophores.
    3. Right Basal Series of head absent.
    4. Arms IV with 3 longitudinal series on arm base (drawing below).

      Figure. Ventral view of right arm IV, holotype, 39 mm ML, female. Drawing from Voss (1969, Fig.15f).
    5. Most species with separate group of 4-8 compound photophores on ends of arms IV (drawing above) (Voss, et al., 1998). Apparently this feature is absent in H. inermis.
    6. Compound photophores of large, uniform size and evenly spaced on anterior 2/3 of ventral mantle.
  2. Tubercles
    1. Absent.

The species differ in the following manner:

Character H. celetaria H. inermis H. pacifica H. sp. A
Club suckers
Asymmetrical outer
sucker rings in:
3 ventral-marginal
sucker series
No asymmetrical rings 2 ventral-marginal
sucker series
No asymmetrical rings
Size of medial
manal suckers:
Slightly larger than
marginal suckers
2 X marginal suckers 1.5 X marginal suckers Slightly larger than
marginal suckers
Large manal-sucker dentition: 12-13 teeth on distal margin 20-27 teeth on entire margin 28-32 teeth on entire margin 15-20 teeth on distal margin
Photophores
Single sawtooth in
Basal Row photophore pattern:
Yes No sawtooth No sawtooth Yes
Number of photophores in Basal Row: 9 10 9 9

With the exception of the analysis of head photophores and the inclusion of H. inermis in this species group, most of the information presented here is from Voss (1969) and Voss, et al . (1998)
