Anisophyllodes Atyeo, 1967


Genus Anisophyllodes Atyeo, 1967  

The genus Anisophyllodes   was originally based on a single species, Anisophyllodes pipromorphae Atyeo, 1967   collected from Mionectes   (5 Pipromorpha   ) oleagineus (Lichtenstein, 1823) ( Tyrannidae   ) from Trinidad and Tobago ( Atyeo 1967). Atyeo (1969) later transferred Alloptes intermedius   described by Trouessart and Neumann (1888), on Elaenia martinica (Linnaeus, 1766)   , to Anisophyllodes   . The latter species was also reported by Cerny and Lukoschus (1975) from E. flavogaster (Thunberg, 1822)   . The main diagnostic features separating this genus from other proctophyllodine genera are as follows: in both sexes, epimerites I free with diverging posterior tips; in males, opisthosoma attenuate to posterior end and with truncated opisthosomal lobes usually separated by slitlike terminal cleft; genital arch and aedeagus short, situated at the level of trochanters IV; setae g and ps3 arranged in a longitudinal rectangle; paired or unpaired pregenital plates are present; adanal shields present. Dimorphism of males was also noted for this genus: in heteromorph males, the opisthosomal lobes bear short and wide terminal lamellae and legs IV are thicker than legs III; in homeomorph males, the opisthosomal lobes lack terminal lamellae and legs III, IV are subequal in size. It is necessary to note that the original diagnosis ( Atyeo 1967) stated that dorsal setae e1 are absent in Anisophyllodes   ; however, this character actually varies among species. In A. intermedius   and in a new species described below these setae are present.
