Stenelytrana emarginata

Classification Diagnostic Features of Larvae
  • Larva. Head quite hairy on anterior portion; epistoma abruptly raised, straight, perpendicular; labrum thick, transverse, broadly rounded from near base, perimeter densely hairy; dorsal angle of mandible abrupt, prominent ; one ocellus; last joint of maxillary palpi acutely conical, equal to last labial, shorter than the others; hypostoma somewhat transversely bulging; gular sutures slightly protuberant, roughened. Proeusternum shining, sternellum dull velvety pubescent on anterior two-thirds; mesonotum and metanotum entirely dull velvety pubescent; femur and tibia subequal, tarsus straight, acute. Ampullae seven-, surrounded by a narrow band of velvety pubescence, tubercles very small, separated, the two median rows (of dorsal ampullae) separated by a transverse band of velvety pubescence. Spiracles rather small, narrowly oval, peritreme thin. Pupa. Form like that of adult, bearing groups of short attenuate spines on anterior median margin and posterior lateral portions of prothorax; two median oval groups on metanotum: a transverse band of more conical spines on each abdominal tergum becoming more irregularly dispersed posteriorly, also several along region of parascutum and epipleurum. This species can be easily recognized by the large size of the matured larvae and the structure of the ampullae, surrounded by velvety pubescence, with also a transverse median band.
