Material examined. HOLOTYPE: male, reared from flat, pustule-like galls on underside of leaves of Psychotria mapourioides   , Guadeloupe, Pointe Noire, Morne-à-Louis, XII- 14-2011, J. Etienne GR 4478, deposited in NMNH.

PARATYPES, all in NMNH: 8 males, 7 females, 5 pupal exuviae, 4 larvae, same data as holotype; 2 females, same data as holotype except IV- 10-2011, GR 4372; 2 males, 2 females, same data as holotype except V- 4-2012, GR 4540; and 2 males and two females, same data as holotype except I- 22-2012, GR 4589.

Etymology. The name tumida   is a Latin adjective meaning swollen, in reference to the enlarged fused female cerci that cover the entire posterior end of the abdomen.

Life history. This species forms circular, flat, blisterlike epidermal galls, about 3 mm in diameter, on the underside of leaves of Psychotria mapourioides   . Each gall is inhabited by a single larva that pupates in the gall. The pupa pushes its way out of the thin-walled gall and the adult breaks out of the pupa. Adult emergence takes place from 8 to 9 a.m. Several generations occur per year. Galls may be found on the same leaves as those of Pellacara postica   .
