Tropideucoila weldi Costa Lima, 1940: 17

Diagnosis. Body stout. Head ( Fig. 9 ) with lateral margin of occiput well defined. Eyes without pubescence. Antennae of female ( Fig. 10 ) pilose, cilindrical, widened towards apex, club 7­segmented, inconspicuous. Dorsal margin of pronotal plate ( Fig. 11 ) with three emarginations; sides of pronotum with longitudinal carinae. Mesoscutum ( Figs. 12 and 13 ) strongly convex in profile, median mesoscutal carina present. Dorsal part of scutellum ( Fig. 13 ) areolate, dorsoposterior part in dorsal view emarginate with two small lateral angles and conspicuous posterior angles. Scutellar plate ( Figs. 12 and 13 ) small, quite elevated, with a circular pit distinctly removed from the posterior margin of the plate. Mesopleuron ( Fig. 12 ) with subalar pit. Metapleuron ( Fig. 12 ) sculptured. Forewings ( Fig. 14 ) hyaline, dusky at base, punctate, apical margin with hair fringe; marginal cell open anteriorly; veins darkened. Metacoxa ( Fig. 15 ) with a band of hairs along the posterior margin. Third abdominal tergum of metasoma ( Fig. 12 ) with a thin hairy ring; metasoma distally smooth.

Geographical distribution. Neotropical Region: Brazil and Argentina ( Loiácono & Diaz 1977). In Brazil it is distributed throughout the States of Rio de Janeiro ( Costa Lima 1940) and Goiás (new record).

Hosts. Lonchaeidae : Neosilba pendula (in Costa Lima 1940).

All the material studied in this paper was collected in the State of Goiás using a Malaise trap.

Remarks. Borgmeier (1935) emphazised that Tropideucoila Ashmead, 1903 is very similar to Dettmeria Borgmeier, 1935 . Costa Lima (1940) described Tropideucoila weldi and remarked its similarity with D. euxestae . The analysis of material collected in Brazil suggested that T. weldi could be better placed in Dettmeria than in Tropideucoila .

Material collected. BRAZIL. Goiás: 25.X.1998 (1 female); 21.XI.1998 (1 female); 22.XI.1998 (1 female); 6.V.2000 (1 female), coll. C. Marchiori ( MLP).
