Tenellia
sp. #29
 
Tenellia sp. #29
Maximum size:  2-3 mm.

Identification:  The body of this aeolid is translucent-cream heavily frosted which opaque white. The rhinophores are translucent-cream with subapical orange bands and there is an orange line at the front of the head. The cerata are sparse and have translucent-cream patches that contain brown flecks.

Natural history:  Tenellia sp. #29 is known from two animals found on and near Pennaria disticha in a Halimeda kanaloana bed at about 9 m (30 ft). It appears to feed on that hydroid.

Distribution:  Maui.

Taxonomic notes:  It was first recorded in Hawaii from Makena Landing, Maui by Jake Brandwine on March 4, 2022. We initially listed these as young Tenellia sp. #11. However, the lack of orange and white flecks on the proximal portions of the rhinophores, the lack of orange flecks on the cephalic tentacles, the lack of  pustules on the sides of the foot, the presence of an orange line on the front of the head and the association with Pennaria disticha, rather than Corymorpha cf. tomoensis, argue against lumping.
