Abstract

The last instar and pupa of Pyropyga nigricans (Say, 1823) are described, illustrated, and compared to those of Pyropyga modesta Green, 1961; these species differ in the color pattern of the pronotum and abdominal tergites, and the morphology of the maxilla and labium. Larvae of the genus Pyropyga Motschulsky, 1852 are compared to those of the genera Lamprohiza Motschulsky, 1853, Lucidota LeConte, 1833, and Phosphaenus Laporte, 1833 (all belonging to the tribe Photinini but to different subtribes); on the basis of general body shape and morphology of the head capsule, antennae, and mouthparts, larvae of the genus Pyropyga seem more closely related to those of the genus Lucidota than to those of the other two genera.

Résumé

On trouvera ici la description illustrée de la larve de dernier stade et de la nymphe de Pyropyga nigricans (Say, 1823), description comparée à celle de Pyropyga modesta Green, 1961; ces espèces diffèrent par la coloration de leur pronotum et de leurs tergites abdominaux, de même que par la morphologie de leur maxille et de leur labium. Le larves du genre Pyropyga Motschulsky, 1852 sont comparées aux larves des genres Lamprohiza Motshulsky, 1853, Lucidota Le Conte, 1833 et Phosphaenus Laporte, 1833 (tous de la tribu des Photinini mais de sous-tribus différentes), quant à leur forme générale, à la morphologie de leur capsule céphalique, de leurs antennes et de leurs pièces buccales, les larves du genre Pyropyga semblent plus apparentées à celles du genre Lucidota qu’aux larves des deux autres genres.
