At present time most of the ecology of Pseudoyersinia pilipes is unknown and its taxonomy needs to be studied (Becerra and Oromi 1999, Bercerra et al. 2001, Wieland et al. 2014). The available data suggest that this species has a very limited distribution (AOO is 40-200 km² and EOO is 74-200 km²) and thus could fall under a threatened category. Further field research is strongly encouraged in a near future. The scarcity of known records gives insufficient information on possible threats and its conservation status is not well defined, therefore the species is assessed as Data Deficient (DD).
Pseudoyersinia pilipes is endemic of the island La Gomera, in the Canary Islands archipelago (Bercerra et al. 2001). The extent of occurrence (EOO) is 74 km² with an upper estimate of 200 km². The area of occupancy (AOO) is 40 km² with an upper estimate of 200 km².
The only confirmed subpopulation of Pseudoyersinia pilipes seems to be resticted to the island La Gomera. The scarcity of collecting records suggests that the population of this species may be extremely small (Bercerra et al. 2001).
From the scarce records available this species seems to be present in the scrubland of the eastern part of the island La Gomera and to be active from March to August (Bercerra et al. 2001).
Research on this species is strongly encouraged to understand its ecology and threats which at present time are practically unknown.
