Trybliographa infuscata Gallardo, Diaz & Uchôa F., 2000: 21

Diagnosis. Body stout. Head ( Fig. 40 ) with lateral margin of occiput not well defined. Eyes without pubescence. Antennae of female ( Fig. 41 ) pilose, cilindrical, widened towards apex, club 7­segmented, conspicuous. Antennae of male ( Fig. 42 ) with the first flagellomere straight, shorter than second. Dorsal margin of pronotal plate ( Fig. 43 ) broadly concave; sides of pronotum smooth. Mesoscutum ( Figs. 44 and 45 ) slightly convex in profile, smooth. Dorsal part of scutellum ( Fig. 45 ) areolate­rugose, dorsoposterior part in dorsal view bluntly rounded. Scutellar plate ( Figs. 44 and 45 ) large, weakly elevated, with an anterior area slightly concave, elliptical pit close to the posterior margin of the plate. Mesopleuron ( Fig. 44 ) without subalar pit. Metapleuron ( Fig. 44 ) almost smooth. Forewings ( Fig. 46 ) hyaline, dusky at base, pubescent, apical margin with hair fringe; marginal cell anteriorly partially open; veins darkened. Metacoxa ( Fig. 47 ) with a band of hairs along the posterior margin. Third abdominal tergum of metasoma ( Fig. 44 ) with a dense hairy ring at base; metasoma distally smooth.

Geographical distribution. Neotropical Region: Brazil. (Gallardo et al. 2000). In Brazil it is distributed throughout the States of Mato Grosso do Sul (Gallardo et al. 2000), São Paulo and Minas Gerais (new records).

Hosts. Lonchaeidae : Neosilba sp. (in Gallardo et al. 2000).

This species was obtained mainly from lonchaeids puparia associated with Rutaceae fruits.

Remarks. Trybliographa Förster, 1869 is mainly holartic ( Nordlander 1981). However, some species of this genus were recorded to the Neotropical Region ( De Santis 1965; 1980; Gallardo et al. 2000).
