IUCN Red Listing Red List Assessment: (using 2001 IUCN system) Least Concern (LC)

Red List Criteria: Date Last Seen (only for EX, EW or Possibly EX species): Is the species Possibly Extinct?  Possibly Extinct Candidate?  Rationale for the Red List Assessment L. pallescens is listed as Least Concern. It has a wide distribution range and the population is believed to be stable at present.
