New Trichogrammatidae (Hymenoptera) from Venezuela

Abstract – Prouscana lineacalvata n. gen., n. sp., Adryas longiclavata n. sp., A. bre-viterebrata n. sp., A. intermedia n. sp., Pseuduscana neotropica n. sp., Lathromeroidealongiclavata n. sp., Burksiella altagraciae n. sp. and B. platysetosa n. sp. (Hymenoptera:Trichogrammatidae) are described from Venezuela.

Key words: trichogrammatid, Prouscana, Adryas, Pseuduscana, Lathromeroidea, Burk-siella, Venezuela.

Among the trichogrammatids collected in Venezuela by one of us (M. V.)several undescribed genera and species have been found. Previously VIG-GIANI & VELASQUEZ (2004) described the unusual genus Pteroanomalo-gramma.

The description of a new genus and of seven new species will be given inthe present paper. Most terms and acronyms used follow DOUTT & VIGGIANI

(1968), others are defined in the text. The holotypes and some paratypeswill be preserved in the entomological collection of the Dipartimento di En-tomologia e Zoologia Agraria «Filippo Silvestri», Università degli Studi diNapoli «Federico II», Portici (NA), Italia. Other paratypes will be pre-served in the entomological collection of the Universidad Nacional Experi-mental Rómulo Gallegos, Área de Ingenería, San Juan de los Morros,Estado Guárico, Venezuela.

Material examined. Holotype, �, Venezuela, Aragua, Cuyagua, 18.XI.1999, coll. J.L.Garcia. Allotype, �, same data as holotype. Paratypes: 1 �, Venezuela, Aragua, Choroní,4.VIII.1999, coll. J.L. Garcia; 1 �, Venezuela, Aragua, Cumboto, 12.VIII.1999, coll. J.L.Garcia.

Comment. The new genus Prouscana clearly belongs to the Trichogram-matidae Oligositinae Chaetostrichini (VIGGIANI, 1971) and appears related tothe genus Uscana Girault, mainly for the antennal features. For somecharacters concerning the dense discal ciliation, the new genus appears al-lied to Tumidifemur Girault. PINTO (2006) apparently widened the defini-tion of the latter genus including also specimens here used to describedProuscana.

Comment. P. neotropica can be distinguished from the only describedspecies of the genus Pseuduscana Pinto (PINTO, 2006), P. sola Pinto, byseveral characters: midlobe of mesoscutum with two pairs of setae, longestfringe setae of the fore wing one/third of the disc and copulatory organwith aedeagus fused with the phallobase which lacks of parameres and dig-iti. According to PINTO (2006) the genus includes species very homogeneousin female sex, yet the male genitalia are more variable and can help in thespecie diagnosis.
