Hosts. Reared from a detachable gall on the stem of Piper sinugaudens (Piperaeae) induced by an unidentified Cecidomyiidae . The gall is spherical, 2.5 cm in diameter and covered with green bracts ( Fig. 8 ). It may actually originate from a bud on the stem (P. Hanson, unpublished).

Distribution. Costa Rica.

Material examined.

Holotype ♀ COSTA RICA, Cartago, Finca Urabá , from Piper gall, M. Blanco ( NHMUK) . Paratypes (6♀ 1♂, MZLU, MZUCR, NHMUK) : 5♀ with same label data as holotype ; 1♀ 1♂ COSTA RICA, Alajuela, Estación Biológica A. Brenes, iii.2002, from Piper sinugaud. stem gall, P. Hanson .

Etymology. Named after the host plant of the gall from which this species was reared.
