description: <i>Mydiognathus</i> n. gen. (Figs 1, 2 a–c, 3 a–c) <b>Type species</b>. <i>Mydiognathus eviohlhoffae</i> Yoshizawa &amp; Lienhard <b>n. sp.</b> <b>Etymology</b>. Named after elongated mandibles (mydion: small forceps in Greek; gnathos: jaw in Greek). <b>Diagnosis</b>. This new genus is a representative of Insecta, Neoptera, Paraneoptera, and a member of the family Archipsyllidae Handlirsch, 1906 (= sister clade to Condylognatha). It can be distinguished clearly from the other genera of this family (<i>Archipsylla</i> Handlirsch, 1906, <i>Archipsyllodes</i> Vishniakova, 1976, <i>Archipsyllopsis</i> Vishniakova, 1976 and <i>Psocopsylla</i> Özdikmen, 2009 [= <i>Eopsylla</i> Vishniakova, 1976, not <i>Eopsylla</i> Argyropulo, 1946; see Özdikmen, 2009]) by the following wing venation characters (Figs 1 a,b, 3 a) (Vishniakova 1976; Huang <i>et al</i>. 2008): Sc in forewing with only two sections (near wing base and at the base of pterostigma) in <i>Mydiognathus</i> whereas an additional section proximally of the pterostigma between wing margin and R 1 in the other genera; basal Cua cross vein (or Cua itself in the sense of Nel <i>et al</i>. 2012) in forewing forked from R+M in <i>Mydiognathus</i> whereas from M in the other genera; areola postica (ap) in forewing strongly constricted proximally in <i>Mydiognathus</i> whereas broadest at the base in the other genera; ap absent in hindwing of <i>Mydiognathus</i> whereas present in the other genera as far as known. Apart from these differences, wing venational and other morphological characters are in good agreement with the features previously described for the family, justifying the placement of <i>Mydiognathus</i> in the Archipsyllidae. For detailed morphological information see the description of the type species.
