Janalia  gen. nov.

Type species. Janalia jarmilae  sp. nov., here designated.

Diagnosis. Species of Janalia  gen. nov. ( Fig. 1 View Figure ) can be recognized within Anisolinina  by the following combination of characters: labrum expanded, each lobe less than two times wider then long and not widely separated medially ( Fig. 5 View Figure ); apical maxillary palpomere distinctly longer than previous segment, weakly dilated fusiform ( Fig. 6 View Figure ), about as broad as previous segment at widest point; apical labial palpomere distinctly dilated, not flattened laterally and with broad apical face ( Figs. 4–6 View Figure ); spines on metatibia thin ( Fig. 1 View Figure ). Accessory basal lines feebly developed and situated laterally. Aedeagus short and compact, with a short, broad paramere bearing many peg setae ( Figs. 11–14 View Figure ).

Description. Form elongate, of medium size. Head small with several macropunctures. Labrum expanded, each lobe less than two times wider then long and not widely separated medially ( Fig. 5 View Figure ); Maxillary palpi with apical palpomere distinctly longer than previous triangular segment, weakly dilated fusiform ( Fig. 6 View Figure ). Labial palpi with apical palpomere distinctly dilated, not flattened laterally and with broad apical face ( Figs. 4–6 View Figure ). Ventral surface of head punctate, mentum markedly transverse ( Fig. 3 View Figure ), gular sutures and gular setae distant ( Figs. 3, 4 View Figure ). Mandibles relatively short and broad, sharp apically ( Figs. 5, 6 View Figure ).

Pronotum with dorsal and lateral series consisting of fine punctures. Prosternum markedly transverse, elevated in middle ( Fig. 3 View Figure ), mesoventrital process acute, extending less than half the length of coxae, posteriomedially with slightly protruding ridges ( Figs. 7, 8 View Figure ), metaventrite slightly produced between coxae. Elytra with punctuation not forming rows or series. Abdomen with accessory basal lines feebly developed and situated laterally. Legs covered with setae, tibiae with lateral spines.

Male. Sternite 7 in apical third with depression with modified erect setae ( Figs. 9, 10 View Figure ). Sternite 8 ( Fig. 9 View Figure ) with posterior margin emarginate. Aedeagus short and compact, with broad median lobe bearing many peg setae ( Figs. 11–14 View Figure ).

Remarks. The general appearance of the new genus is similar to that of Barygnathus  or Trigonopalpus  . Janalia  gen. nov. shares with Barygnathus  the expanded labrum, the aedeagus shape and the distant gular setae, but differs from the latter by the apical labial palpomere not laterally flattened and with a broad apical face. The new genus shares with Trigonopalpus  the apical labial palpomere not laterally flattened, with broad apical face, but differs by the latter by the different aedeagus shape and the distant gular setae. In the key to genera of the Tympanophorus  lineage, Janalia  gen. nov. keys out near Bombylodes  and Pammegus  (see below), but differs at least from Pammegus  (the male of Bombylode s is unknown yet) by short and compact aedeagus with a short, broad paramere. The new genus differs from Bombylodes  mainly by different setation patterns on head and by different shape of head, which is strongly trapezoidal in Bombylodes  .

Etymology. The genus is dedicated to my wife Jana for her generous long-term support of my activities in entomology. The name is a feminine, consisting of the name Jana and “lia” as a combination of letters.
