Cladistic Assessment, Key and Description of Two New Neotropical Genera and Species of Gabuniina (Hymenoptera: Ichneumonidae: Cryptinae)

The Cryptini Fenixia n. gen., from the Brazilian Atlantic Forest, and Dineotropica n. gen., from the Amazon basin, are proposed, described, and cladistically compared with literature data for representative species of all genera of the subtribe Gabuniina and 38 outgroup species. A total of 72 species and 51 characters are evaluated. Implied weighting results suggest that Fenixia is closely related to Lagarosoma Gupta, while Dineotropica is closest to Cestrus Townes. Unweighted analyses were inconclusive, but implied weighting results support the monophyly of Gabuniina essentially as defined in the literature, and suggest that Wuda singularis, and perhaps a few other taxa of Ceratocryptina, might be part of, or a sister taxon of that subtribe. The species Fenixia curta n. sp. and Dineotropica lissa n. sp. are described and illustrated. A key to genera of neotropical Gabuniina is presented.
