Comment from Richard Willan on photo #91
Although the orange spotting on the mantel is similar to Halgerda carlsoni and Halgerda brycei, Halgerda stricklandi is the only one with longitudinal black stripes on the rhinophores and gill axes.

Halgerda carlsoni is most similar to Halgerda batangas. However, Halgerda carlsoni has microscopic orange speckles between the ridges (very rarely these speckles join up to form lines) and even when they are lines, they never form into a network of intersecting lines as in Halgerda batangas.

Halgerda malesso has much lower pustules, yellow spots and yellow lines. There are far fewer yellow lines than in Halgerda batangas.

Halgerda bacalusia has the summits of the ridges with strong dark orange lines and microscopic orange speckles between the ridges.

Here a description from Dr. Dave Behrens:
Halgerda bacalusia: broad orange lines follow the ridges to the orange tipped tubercles
Halgerda batangas: network of orange lines between the tubercles, rather than a series of spots
Halgerda carlsoni: the are lines of minute orange spots between the tubercles
Halgerda malesso: no lines between the tubercles, only along the margin
Halgerda stricklandi: orange tubercles arranged randomly, not in ridges. Orange spots not connected
