Specimen labels

The holotype and two additional specimens, putatively identified as P. gibba (Than, 1978), from the Andaman Islands (BMNH) and the Philippines (MCZC) were the only known specimens of this species. However, the recent fogging activities of M.M. Bos in Lore Lindu NP(Baloli, Gn. Kalabul, Kaha) and surrounging agricultural land (cacao agrof.) provided several additional specimens of this rare species. (Kohout 2008)


Kohout (2008) - As the name suggests, P. gibba is characterised by a highly arched (gibbose) mesosomal dorsum.
