Threats This species occurs in a variety of habitats and may tolerate some disturbance. It suffers from the general threats of human induced habitat loss and degradation.

Past Present Future 1 Habitat Loss/Degradation (human induced)    Conservation Measures This species has been recorded from Cat Tien National Park in Vietnam. It is also recorded from Xishuangbanna Tropical Botanical Garden, Yunnan, China. It was not found in available lists of bank species. In view of some past difficulties with separation of this species from M.interrupta further taxonomic research is recommended.

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 The extent of occurrence (EOO) for this species exceeds the critical threshold for a threatened category. The estimated area of occupancy (AOO) and inferred population also exceed the thresholds. It is found in a variety of habitats and may tolerate some disturbance. It is assessed as Least concern (LC). However, further research is needed to establish the current population status and trends. Reason(s) for Change in Red List Category from the Previous Assessment:  Genuine Change  Nongenuine Change  No Change  Genuine (recent)  New information  Taxonomy  Same category  Genuine (since first assessment)  Knowledge of Criteria  Criteria Revisio and criteria  Incorrect data used  Other  Same category but previously change in criteria Current Population Trend: Unknown Date of Assessment: 23/08/2010 Name(s) of the Assessor(s): H.Chadburn Evaluator(s): Notes:
