[Supplementary Material] Description of the Mature Larva of Synergus filicornis (Hymenoptera: Cynipidae: Synergini), with Notes on the Immature Larvae
Keywords:
Cynipoidea, larval phase, morphology, phylogenyAbstract
The final instar larva of Synergus filicornis (Cameron) (Hymenoptera: Cynipidae: Synergini) is described and illustrated. Morphological structures of a diagnostic value are discussed. The most remarkable character states shown by the mature larva of this species lie in the integument, which unlike the rest of described cynipoid mature larvae, presents tegumental differentiations. Additionally the antennal orbits, unlike those of other described Synergini mature larvae, did not present one seta on each antennal orbit. The immature larvae can be differentiated from the mature larva by the following characters: a) number and location of sensorial tegumental differentiations on the head, b) number of sensilla on the maxillary palpi, and c) morphology of the mandibles. The determination of the mandibles size, in this species, permits the estimation of the larval stages number.
Se describe la larva madura de Synergus filicornis (Cameron) (Hymenoptera: Cynipidae: Synergini). El carácter diagnóstico básico más relevante, mostrado por este último estado larvario, radica en que el tegumento, a diferencia del resto de larvas maduras descritas de Cynipoidea, presenta diferenciaciones. Adicionalmente, las órbitas antenales, a diferencia de otras larvas maduras descritas de Synergini, no presentan una seta en cada órbita antenal. Las larvas immaduras se diferencian de las larvas maduras en los siguientes estados de carácter: a) número y situación de las diferenciaciones tegumentarias sensoriales de la cabeza, b) número de las sensilas de los palpos maxilares y c) morfología de las mandíbulas. El tamaño de las mandíbulas permite, en esta especie de inquilino, estimar el número de estados larvarios.
