Basically black describes many Pamphobeteus species, both those described in the late 1800s/early 1900s and those more recently introduced. In addition to taxonomic differences, there are differences in size, setae, and even behavior. Contrast Pamphobeteus sp. “mascara,” whose only parts that can be said to be black are the femurs. The rest is a study in brown and red. Size also distinguishes P. sp. “mascara.” Those grown here to adulthood are at least an inch larger than P. sp. “cascada,” a species introduced to the US hobby alongside P. sp. “mascara” about 5 years ago.
P. sp. “mascara” comes from Ecuadorian dry coastal forest, near Manabi. P. sp. “mascara” is different from other Ecuadorian Pamphobeteus species, including P. ultramarinus, P. sp. “costa,” P. sp. “Machala,” P. sp. “Manabi,” P. sp. “nigricolor,” and P. sp. “south Ecuador II.” Captive-bred lineages are sustained overseas. Keeping parameters are the same as those for Pamphobeteus in general.
