Tryphopsichara   gen. nov.

( Figs 7 View Figs 1–12 , 33–37 View Figs 24–34 View Figs 35–47 )

Diagnosis: The habitus of the new genus is similar to Bolitochara MANNERHEIM, 1831   from the holarctic region, but the labial palpi are thick or stout ( Fig. 35 View Figs 35–47 ), the mandibles very long ( Fig. 7 View Figs 1–12 ), and the labrum with two spines on the anterior edge ( Fig. 37 View Figs 35–47 ), while in Bolitochara   is without spines. The mesosternum of the new genus is keeled only at the base, whereas in Bolitochara   is keeled throughout its length. The mesocoxae in Bolitochara   are slightly separated, in the new genus contiguous.

Description: Habitus as in Fig. 7 View Figs 1–12 . Antennae 11-segmented. Eyes shorter than the postocular region in dorsal view, temporal sulcus present. Upper surface of labrum with two spines on the anterior border ( Fig. 37 View Figs 35–47 ); labial palpi 3-segmented ( Fig. 35 View Figs 35–47 ), all segments short and broad; ligula short with apical plica oval, shortly splitted at the apex ( Fig. 35 View Figs 35–47 ); paraglossae not protruding in front ( Fig. 35 View Figs 35–47 ); maxillary palpi 4-segmented, the second one narrow, the third one broad, the apical segment awl-shaped and very short ( Fig. 36 View Figs 35–47 ), the inner lobe pointed at apex, the outer a little longer than the inner ( Fig. 36 View Figs 35–47 ). Anterior edge of mentum emarginate ( Fig. 34 View Figs 24–34 ). Mandibles very long and narrow, the left with a weak inner tooth. Mesosternum shortly keeled at base, mesosternal process acute, mesocoxae contiguous. Tarsal formula 4-4-5. First posterior tarsomere as long as the two following bringing together. Spermatheca as in Fig. 33 View Figs 24–34 , mentum as in Fig. 34 View Figs 24–34 , superior labrum as in Fig. 37 View Figs 35–47 .

Τype species: Tryphopsichara australiana   spec. nov.

Etymology: The name of the new genus is composed by the Greek words τρύφος = stumpy, όψις = aspect, facies and ΧΆρα = joy.
