Swammerdamia Group |
Pseudoswammerdamia (1S)
Male genitalia: valvae with pointed apex and distal triangular process; surface of aedeagus dentate
Female genitalia: posterior part of ductus bursae strongly sclerotised
Swammerdamia (4S)
Male genitalia: valvae rounded at apex, without protruberances
Paraswammerdamia (2S)
Male genitalia: saccus expanded at apex, valvae with protruberance from ventral edge
Female genitalia: lamella postvaginalis conspicuously broadened
These 3 genera are very similar and could be regarded as subgenera of Swammerdamia
Adults rest with head down and abdomen raised (as in Argyresthia)
Head tufted between antennae; frons with appressed scales; Ocelli present
Antenna 3/4 length of forewing; Labial palps short, nearly straight, porrect; S2=S3
