diagnosis
Diagnosis. Within the A. flavidus (Winnertz) group (Jaschhof & Jaschhof 2009: 228 ff.), both A. internuntius and A. stylifer are distinguished by the finger-like processes of the tegmen being unusually thin and situated in a cavity near the apex rather than in the center. As a distinction, in A. internuntius the cavity is slightly larger and more clearly defined (Jaschhof 2003: fig. 2 C) compared with A. stylifer (Jaschhof & Jaschhof 2009: fig. 77 C). A more obvious difference is the posterior edge of the subanal plate, which in A. internuntius is markedly concave medially and equipped with two short processes laterally, whereas in A. stylifer it is nearly straight with inconspicuous, lateral sclerotizations (see fig. 2 C versus fig. 77 C). A peculiarity of the subanal plate of A. internuntius is that the central portions often have a few setae. Finally, the two teeth on the gonostylus of A. internuntius are slightly stronger than those in A. stylifer, which however can be appreciated only in specimens compared side by side.
