Figs. 5–19 View FIGURES 5 – 13 View FIGURES 14 – 18 View FIGURE 19

Description. Adult: Wing ( Fig. 8 View FIGURES 5 – 13 ), length: male 1.8 mm (n= 2); female 1.7–1.9 mm (n= 5). Antenna ( Figs. 6–7 View FIGURES 5 – 13 ); male with 15–16 flagellomeres (n= 2), female with 17–18 (n= 5). Palpus of 3 segments, the third at least twice as long as second, with the exception of 4 segments on one palpus of one specimen, in that case the third and fourth segments each barely longer than second. Acropods as in Figs 9–10 View FIGURES 5 – 13 . Anepimeron with 12–17 setae (n= 8). Male postabdomen and terminalia as in Figs. 11–13 View FIGURES 5 – 13 . Female postabdomen as in Figs. 14–16 View FIGURES 14 – 18 .

Pupa. Anterior segments ( Fig. 17 View FIGURES 14 – 18 ) as in the generic description.

Larva, third instar ( Fig. 19 View FIGURE 19 ): Length, 1.7–1.9 mm (n= 5). White. Spatula as in Fig. 18 View FIGURES 14 – 18 . Papillae as for generic description.

Material examined. HOLOTYPE: male, reared from leaf galls of Faramea occidentalis   , Guadeloupe, Bouillante, Pigeon, V- 17-2014, J. Etienne GR 4631, deposited in NMNH. PARATYPES, all in NMNH: male, 15 females, 5 pupal exuviae, same data as holotype; 4 larvae, same data as holotype except III- 15-2012, GR 4605; 3 larvae, same data as holotype except IX- 1-2012, GR 4562; and 6 larvae, 2 pupal exuviae, same pertinent data as holotype except St.-Claude, Beausoleil, IX- 2-2011, GR 4407.

Etymology. The name planicauda   is a noun in apposition that combines the Latin words planus and cauda, meaning flat and tail, respectively. The name refers to the dorsoventrally flattened female cerci.

Life history. This species forms large, hemispheroid galls up to 1 cm in diameter that show on both sides of the leaves of Faramea occidentalis   ( Fig. 1 View FIGURES 1 – 4 ). Individual galls may coalesce. Galls are inhabited by one to several larvae, each in its separate chamber. Pupation takes place in the gall. When the adult is fully formed, the pupa exits partway out of the gall from the underside of the leaf, and the adult then emerges from the pupa. Several generations occur per year.
