Astenus bifidus Lecoq, 1996

( Figs. 24–30 )

Astenus bifidus Lecoq, 1996: 25 ; Janák & Lecoq, 2007: 330.

Type locality. Central Madagascar, Ankaratra Mts., Manjakatompo .

Material examined (1 specimen). MADAGASCAR: 1 ♂: AMBOHITANTELY Spec. Res., S18°10’17.9‘‘, E47°16’36.9‘‘ 1584m; Malaise trap, 17.-25.xi. 2011, P. Baňař lgt. ( MMBC) .

Distribution. The holotype was described from Manjakatompo in Ankaratra Mts. The second specimen (female) from Ambialialika was attributed originally with some doubts to this species ( Janák & Lecoq 2007). The new records is situated far north of these localities.

Note. The shape of red spots on the elytra is variable: limited on transverse bands at posterior sixth (type) or third of elytra (Ambialialika and Ambohitantely – Figs. 24–27 ). Aedeagus ( Figs. 28, 29 ) and posterior margin of the male sternite VII ( Fig. 30 ) of the specimen from Ambohitantely are very characteristic for this species and confirm identity of both specimens with the holotype.
