Chrysonotomyia dussiae Paniagua & Hansson sp. n.
Figure 2 View FIGURE 2 .
Etymology. In reference to the plant genus Dussia .
Material examined. Holotype female labeled “ Panama, Prov. Colón. Área Protegida San Lorenzo, Dosel, 1999, galls on Dussia munda, E. Medianero ” ( LUZM). Paratypes: eight females, four males with same label data as holotype ( MEUP).
Diagnosis. A completely non-metallic yellowish-white species that is very poorly sclerotized.
Description. Length of body female 0.4–0.5 mm, male 0.4 mm. Female and male with head, antenna and body yellowish-white, without metallic tinges, apical part of ovipositor sheaths pale brown. Wings hyaline in both sexes.
Antenna as in Fig. 2 View FIGURE 2 a. Male antenna with short verticillate setae. Frons and vertex weakly reticulate; frontal suture slightly V-shaped. Vertex with very weak reticulation and with grooves. Occipital margin rounded. Ratios: HE/MS/WM = 5.1/1.0/3.4; POL/OOL/POO = 1.6/1.1/1.0; WH/WT = 1.1.
Mesoscutum and scutellum with very weak and medium sized reticulation, notauli visible in anterior fourth. Dorsellum convex not hidden under scutellum, with very weak reticulation. Transepimeral sulcus strongly curved. Forewing with speculum closed below; without stigmal hairlines, radial cell bare ( Fig. 2 View FIGURE 2 c). Propodeum smooth, without median carina. Ratios: LW/LM/HW = 1.7/1.0/1.2; PM/ST = 0.8.
Female gaster ovate. Male digitus as in Fig. 2 View FIGURE 2 b. Ratio of MM/LG = 1.0.
Host. From Cecidomyiidae galls on Dussia munda (Fabaceae) .
Distribution. Canopy of the San Lorenzo Protected Area, Provincia de Colón, República de Panama.
Identification. This species belongs to the auripunctata -group (sensu Hansson 2004) and using the key in Hansson the female runs to couplet 61. This couplet should be modified as follows to include C. dussiae : 61(60) Pronotum comparatively large, especially laterally .............................................................. C. albogilva Hansson - Pronotum hardly visible in dorsal view ............................................................................................................. 61a 61a(60)Vertex with grooves ( Hansson 2004, fig. 25) ............................................................................ C. galbina Hansson - Vertex without grooves .............................................................................. C. dussiae Paniagua & Hansson sp. n.
The male of C. dussiae runs to couplet 65 in Hansson (2004); to include this species the key should be modified as follows:
65(64) Mesepimeron yellowish white to pale yellow non-metallic ............................................................................. 65a - Mesepimeron brown with metallic tinges ............................................................................... C. galbina Hansson 65a(65) Midlobe of mesoscutum with anterior half golden-green and scutellum with posterior two thirds golden-purple ............................................................................................................................................ C. cnecosoma Hansson - Mesoscutum and scutellum yellowish-white ............................................. C. dussiae Paniagua & Hansson sp. n.
