Anoplius (Dicranoplius) diphonichus (Spinola, 1851)

Pompilus diphonichus Spinola, 1851 , in Gay , Historia de Chile, Zool., 6: 381 [Type: ♀, Chile ( MRSN)].

Diagnosis. For A. diphonichus , both sexes have a black head and mesosoma, a reddish orange metasoma, and the setae are black not forming any discernible pattern, except for the clypeus and face below the antennal insertions of the male, which is covered in silver setae ( Figs. 2 a). Additionally, the female has three comb spines and the last metasomal tergum has thin setae, while the aedeagus of the male is slightly longer than the parapenial lobes and has expanded apical lobes ( Fig. 3 in Evans (1969)).

Remarks. This species is the only species of Dicranoplius to be found in Chile. Although the holotype was not studied, specimens identified by Evans (1969) deposited in the FSCA collected by C. Porter were studied. Evans (1969) states that he had little material to study (19 females, 15 males). Due to the collecting efforts of F.D. Parker and M.E. Irwin, substantially more specimens have been collected both in Chile and Argentina, and it seems that this species is more wide spread in Argentina than originally thought by Evans (1969). Evans (1966) misspelled the specific epithet in the female key as diphonicus and this misspelling now can be found in many collections.
