forming robust, rigid, unbranched colonies with strongly fascicled stems. Division into internodes indistinct, but each module with a proximal, frontal nematotheca, a cladial apophysis with its conical nematotheca and a pseudophylactocarp, as well as a fronto-axillar nematotheca. Pseudophylactocarps composed of a long succession of internodes bearing a mesial and two lateral nematothecae. Cladia close to one another, composed of short internodes, each accommodating a strongly S-shaped hydrotheca and its 3 gutter-shaped nematothecae; mesial one half adnate, projecting obliquely upwards, overtopping hydrothecal rim; the latter with strong median triangular cusp and 3 lateral pairs of wider and lower cusps. Corbulae on modified cladia, after a sequence of two normal cormidia; rachis geniculate, repetitive units with a costa and a spout-like nematotheca lateral to it; each costa with a proximal nematotheca, a hydrotheca with a posterior nematotheca and a downwardlydisplaced mesial nematotheca, so as to give rise to a sequence of internodes, each with a complement of 3 nematothecae. Gonothecae lenticular, flimsy, inserted at the base of costae.

However, in none of these the hydrothecae are produced abaxially (in their lower halves) to a similar extent, and their apertures are less tilted frontally. In addition, the new species is a much more robust hydroid, with a thick and strongly fascicled stem, with longer and densely-set cladia, and with profuse, defensive structures, the pseudophylactocarps.
