Abstract
    Two alpha growth form species of boring sponges, Cliona pocillopora sp. nov. and Cliona mucronata are described from coral reefs in the Mexican Pacific Ocean. Cliona pocillopora sp. nov. is a light brown sponge containing tylostyles that measure 146x5 µm. Tylostyles are generally curved and have a globular or mucronated head, sometimes placed at some distance from the proximal end. In addition, straight, short and thick tylostrongyles and centrotylote oxea occasionally appear. Cliona mucronata is reported for the first time in the eastern Pacific Ocean. It is a red to red-orange sponge with two types of tylostyles, long and slender tylostyles, and short ensiform tylostyles. Both species have been found exclusively excavating corals of the genus Pocillopora. The boring activity of Cliona pocillopora sp nov. produces a network of galleries with mainly rectangular or polygonal chambers measuring from 0.7 to 2.4 mm in diameter, and C. mucronata produces a network of reticulate galleries with irregularly spherical or ovoid chambers 1.14x0.67 mm in diameter.
