Perhaps appreciated most for bright pink metallic accents on the mature male, Pamphobeteus sp. “platyomma” is otherwise notable for subtle brown shades in females and immature males. As with all Pamphobeteus, base colors are brightest after a molt. The original Pamphobeteus platyomma was collected in Brazil (Mello-Leitão 1923). Whether the current hobby species is the same as that described by Mello-Leitão is unknown and perhaps doubtful. It is not known precisely where the type species and the current hobby form were collected. In 2001, Pamphobeteus platyomma was deemed nomina dubia.  A consequence of these uncertainties is that the current hobby form is probably best referred to as P. sp. “platyomma.”
P. sp. “platyomma” remains popular in the hobby and is frequently requested. Over the years, various ‘color forms’ have appeared, the most recent being P. sp. “platyomma” (hell bright). Whether these are color variants or different species remains to be seen.
P. sp. “platyomma” spiderlings have the Christmas tree abdominal pattern.
