Sporrongia Gumovsky, 1998

Sporrongia Gumovsky, 1998:31 .

Type species: Sporrongia tobagoiensis Gumovsky , by original designation.

Diagnosis. Posterior ocelli situated very close to occipital margin ( Figs 17, 20 ); clypeus not delimited ( Figs 11–16 ); pronotum strongly reduced and not visible in dorsal view ( Figs 18, 21 ); anterior ½ of notauli as distinct and deep grooves ( Figs 18, 21 ); transscutal articulation between midlobe of mesoscutum and mesoscutellum is a wide and deep groove ( Figs 18, 21 ); axillae strongly advanced forward, so that at least ½ of axillae is in front of anterior margin of mesoscutellum ( Figs 18, 21 , 24 ); dorsellum hidden under mesoscutellum and not visible in dorsal view ( Figs 18–22 , 25 ); antenna with 1–2 anelli ( Figs 4, 7, 10 ).

Biology. No biological information was available when the genus was described. One of the species described here, S. marginata , is based on a long series of both females and males that have been reared from round succulent galls on Andira inermis (Leguminosae) in Costa Rica. No other insects were reared from these galls. It is not established whether Sporrongia marginata is a parasitoid on a gall inducer or is the actual gall inducer, but the absence of other gall inhabitants might suggest the latter. However, further investigations are required to establish this with certainty.

Distribution. Costa Rica (new record), Mexico (new record), Peru (new record), Trinidad & Tobago ( Gumovsky 1998).

Identification. The best option for identification is to use the multiple entry key to the Neotropical genera of Entedoninae on the website www.neotropicaleulophidae.com. Sporrongia does not run smoothly in the key to Nearctic Eulophidae ( Schauff et al. 1997) , but can be easily distinguished from all other Entedoninae in this key through the shape of the notauli.
