Diagnosis
This new species can be recognized by having the antennal setae longer than the width of the flagellomeres; median pronotal sulcus present and foveolate; median mesonotal sulcus absent, at most with a long fovea near the posterior margin; PPP short, basal width nearly equal to its length; the hypopygium longer than wide, with the posterior branches short ( Fig. 8G View Fig ); genitalia with dorsal harpe filamentary, and narrower than ventral harpe.
This species is similar to I. exilisulcus sp. nov. by sharing the simple aedeagus without a sickle-shaped process apically. However, I. afoveatus sp. nov. can be distinguished by having the mesoscutum and mesoscutellum not foveolate (more or less foveolate in I. exilisulcus ); the mesoscutellum without a medio-longitudinal suture (present in I. exilisulcus ); the basal width of PPP nearly equal to its length (two-thirds of length in I. exilisulcus ); T2 with sparse punctures (denser in I. exilisulcus ).
Etymology
The specific epithet ‘ afoveatus ’ is a combination of the Latin words ‘ a ’ (for ‘without’) and ‘ foveatus ’ and refers to the absence of foveae on the mesoscutum and mesoscutellum.
