First described by Frederick Octavius Picard-Cambridge in 1902 from an adult male collected in Amula, Guerrero, Mexico (Brady, 1964). Unfortunately there is little information available on this species, and the description by Brady (1964) was based on preserved specimens.
P. longipalpis is very similar in appearance and habits to P. viridans, and often confused with viridans. Adults can easily be seperated by examination of the sexual organs (Brady 1964).
Note the cream colored endites, a characteristic of longipalpis. (Brady 1964)
It is possible that the presence of white hairs on the abdomen is key for the species.
It also appears that longipalpis lacks the chevron pattern typically seen in viridans, and Brady (1964) describes them as lacking white spots, bars and longitudinal white stripes, although white markings are present in some specimens.
The legs are also shorter in proportion to body length when compared to viridans (Brady, 1964), and a shorter, more rounded abdomen.
