Description: Head elongated ovoid, with flattened occiput; anterior clypeal margin shallowly arcuate; eyes small; scapes reaching but not surpassing occiput. Alitrunk with four pairs of erect hairs, one pair on the propodeum; propodeum profile with a distinct dorsum and rounded transition into the short declivity. Golden yellow, legs and antennae same colour, gaster darker; very shiny without any obvious sculpturation.
TL ca 1.4, HL 0.40, HW 0.33, SL 0.35, funiculus 0.48, PW 0.22, AL  0.39, posterior femur 0.4, CI 81, SI 105, EI 21.

Material examined. Holotype worker and one paratype worker. Collection code SL 105. From Sinharaja Forest Reserve, Sri Lanka, 0620'-0626' N, 8023'-8033' E; 173-657 m asl; collected by N R Gunawardene, pitfall traps, iii.2005-iii.2007.

The type of Paraparatrechina minutula can be seen at http://www.antweb.org/specimenImages.do?code=casent0911017
