Halgerda batangas is characterized by orange-red tipped tubercles,
a network of solid red-orange lines on the dorsum between the tubercles,
and a white region around the mantle edge containing orange-capped tubercles.
The tubercles have a basal ring of white. This shot shows
two specimens mating. More informations on Halgerda batangas are at
