COLOR PHOT - Sp. from Panay I.
[TYPE SPECIES B. excelsus ] [angusticollis][ B. philippinensis]
Diagnoses of genera
of South East Asia: 51.3 Ant mimics, coloured black, brown or
amber. Found on shrubs, on plants and in leaf litter. General remarks:
Most, and the best, ant mimicking salticids do not prey on ants but appear to
gain protection by living close to ants. These spiders are more or less coloured
black, brown or amber depending on the colour of the ants they are mimicking.
When running with ants, it is the movements that the spider has to make in order
to avoid and keep the ants at an acceptably safe distance that signals the presence
of the spider. Other, but not nearly so good, ant mimicking spiders actually
prey on ants. It is fascinating and rewarding to watch one of these salticids
stalking and killing an ant. Another useful clue to the presence of ant mimicking
salticids is when an observer sees what appears to be an ant emerging from a
silken cell! Genus: Bocus (5-6; 5-12). There are only two species
in Bocus [now 3 - J. Proszynski]. The genus differs from Myrmarachne
in microscopic details and in the field its appearance is indistinguishable
from Myrmarachne .
Distribution: Bocus is known only from the Philippines. Murphy
