Tubulophilinopsis sp. #1
Maximum size: 30 mm.
Identification:
This
is
a cream animal reticulated with brown or gray. The
parapodia are margined in iridescent yellow-green and the reticulations
usually extend onto the foot (unlike in Tubulophilinopsis
pilsbryi). Rarely, reticulation on the foot may be absent or barely indicated.
Natural history:
Tubulophilinopsis sp. #1
is a moderately rare nocturnal species typically found in mixed habitats at
depths of about 1 m (3 ft). Rarely, it can be found in up to 24 m (80 ft). It occurs in moderately protected to
highly exposed sites. It lays a barrel-shaped, white egg mass
composed of a tangled egg string. The mass may be anchored in sand or
algal turf and is usually shorter than in Philinopsis
speciosa. Hatching
occurs in
about four days in the laboratory.
Distribution: Big Island, Maui and Oahu.
Taxonomic notes:
Tubulophilinopsis sp. #1
has been listed on-line as a form of Tubulophilinopsis
reticulatus. However, Terry Gosliner feels there are enough
differences from the Indo-Pacific populations of that species to
suggest a split. (pers. com.) It was first recorded in Hawaii from
Pupukea,
Oahu by Scott Johnson on Aug.
12, 1985. It is illustrated as "Pilsbry's headshield slug" in Hoover,
1998 and in the inset photo under that species in Hoover, 2006. A related form is illustrated in Gosliner, et. al., 2018 as a Philinopsis sp.
