Chrysonotomyia claviger Paniagua & Hansson sp. n.

Figures 6 , 7 , 13 , 14 b.

Etymology. Meaning “carrying a clava" referring to the distinct antennal clava.

Material examined. Holotype female labeled “ Panama: Provincia de Panama, Parque Natural Metropolitano, ii.2006, M. Paniagua, agallas de Copaifera sp. ( Fabaceae )” ( LUZM). Paratypes: 21 females with the same label data as holotype ( MEUP); one female from same locality as holotype but collected 6.iii.1998 and from an unidentified gall on Serjania mexicana ( LUZM); six females with the same label data as holotype (USJ); five females with the same label data as holotype ( MNCN).

Diagnosis: Postmarginal vein 1.6x as long as stigmal vein; submarginal vein with three setae; antenna with a well defined clava; frons, vertex and mesosoma dark brown with metallic tinges; vertex reticulate; gaster round.

Description (female). Length of body 0.9–1.1 mm. Antenna dark brown. Frons, vertex and occiput dark brown with metallic tinges. Mesoscutum, scutellum and lateral mesosoma black with metallic tinges (goldengreen or bluish-purple). Coxae dark brown with metallic tinges; fore and mid femora dark brown with metallic tinges, hind femur dark brown with metallic tinges with apical fourth yellowish-white; fore tibia yellowish-brown, mid and hind tibiae dark brown with metallic tinges, with apical third yellowish-white. Forewing hyaline. Petiole yellowish to pale brown. Gaster pale brown to dark brown with metallic tinges, anterior part of first tergite smooth and shiny with golden-green or green metallic tinges, remaining tergites weakly reticulated, with golden-purple tinges ( Fig 7 b).

Antenna with apical three flagellomeres fused and forming a well defined clava ( Fig. 6 a). Frons with strong reticulation, frontal suture straight or slightly V-shaped ( Fig. 13 ). Vertex reticulate. Occipital margin rounded. Ratios: HE/MS/WM = 3.6/1.0/1.7; POL/OOL/POO = 4.4/1.2/1.0; WH/WT = 1.2.

Mesoscutum and scutellum with strong small meshed reticulation, notauli not visible. Dorsellum hidden under scutellum in dorsal view. Transepimeral sulcus weakly curved. Forewing with speculum open below; radial cell bare but without stigmal hair lines ( Fig. 6 b). Propodeum with very weak reticulation; propodeal callus with three setae. Ratios: LW/LM/HW = 1.9/1.0/1.4; PM/ST = 1.6.

Gaster round. Ratio of MM/LG = 1.2.

Male. Unknown.

Host. From unidentified gall-midges ( Diptera : Cecidomyiidae ) on Copaifera sp. ( Fabaceae ) ( Fig. 14 b) and Serjania mexicana (Sapindaceae) ( Fig. 14 d).

Biology remarks. C. claviger was the only species found parasitizing the globular galls of Copaifera sp.

Distribution. Understorey of Parque Natural Metropolitano, Provincia de Panama, República de Panama.

Identification. C. claviger belongs to C. neeigena -group (sensu Hansson 2004) and using the key in Hansson (2004) runs to couplet 78. To include this species in the key, this couplet should be changed as follows:

78(77) Postmarginal vein at least 1.6x as long as stigmal vein........................................................................................ 79 - Postmarginal vein shorter, at most 0.8x as long as stigmal vein .......................................................................... 83

Then, it keys to couplet 82, and to include C. claviger the key should be modified as follows:

Couplet 81, second alternative leads to 82a, not 82.

82a. Antennal clava distinctly wider than the funicular segments, postmarginal vein only 1.6x as long as stigmal vein ... ......................................................................................................................... C. claviger Paniagua & Hansson sp. n. - Antennal clava about as wide as the funicular segments, postmarginal vein 2.9–3.2x as long as stigmal vein ....... 82
