Type material. Holotype male from PERU, JUNÍN: Satipo, Rio Venado , IX.2012, local collector ( MZSP, formerly DHCO) . Paratype female, same data as holotype ( DHCO).

Etymology. The epithet of this new species refers to the Asháninka indigenous people living in the area where the holotype was collected. The name “ ashaninka ” is used as a noun in apposition.

Remarks. As the color in the holotype and paratype are considerably different, it is expected to find more chromatic variations in the species.

The male of Callanga ashaninka sp. nov. ( Fig. 45–48 ) differs from that of C. trichocera ( Fig. 40 ) by the shorter antennae, reaching elytral apex at base of antennomere VII (longer, reaching elytral apex before apex of antennomere V in C. trichocera ), antennomeres dark brown (antennomeres V–XI orangish-brown in C. trichocera ), and pronotum with T-shaped dark brown area anteriorly (with transverse dark brown macula in C. trichocera ). The female of Callanga ashaninka sp. nov. ( Fig. 49–52 ) differs from that of C. trichocera ( Fig. 37–39 ) by the pubescence and erect setae shorter ( Fig. 52 ) (longer in C. trichocera ( Fig. 39 )), and pronotum with T-shaped dark brown area anteriorly (with transverse dark brown macula in C. trichocera ). The female of Callanga ashaninka sp. nov. differs from that of C. tenebrosa ( Fig. 34–36 ) by the pubescence and erect setae shorter (longer in C. tenebrosa ( Fig. 36 )), pronotum with T-shaped dark brown anterior area (entirely dark on wide central area in C. tenebrosa ), and sides of prothorax entirely yellowish-brown ( Fig. 51 ) (brown with large, transverse yellowish-brown macula in C. tenebrosa ( Fig. 35 )).

The three species of Callanga were described from Peru ( C. trichocera also occurs in Bolivia).

Type material. Holotype female from COLOMBIA, BOYACÁ: Otanche , 05.V.2018, local collector ( TAMU, formerly DHCO).

Etymology. The epithet “ lazulina ” refers to lapis lazuli, a deep-blue mineral, alluding to the predominant blackish-blue color of the holotype.

Remarks. Galileo and Santos-Silva (2016) discussed the differences between Fredlanea Martins and Galileo, 1996 and Eulachnesia Bates, 1872 . Even so, the differences between these genera are still very problematic and, depending on the feature considered, Fredlanea may in the future prove to be a synonym of Eulachnesia . This is particularly true if the humeral carina was considered because both the type-species of Eulachnesia ( Amphionycha sapphira Bates, 1866 = Saperda humeralis Fabricius, 1801 ) and Fredlanea ( Eulachnesia velutina Lane, 1966 ) have very distinct humeral carina. On the other hand, there are species in both genera lacking humeral carina. The new species is allocated in Fredlanea because it has no squamiform setae on the elytra.

Fredlanea lazulina sp. nov. differs from F. aequatoria (Bates, 1881) , F. consobrina ( Lane, 1970) , F. flavipennis (Lane, 1966) and F. hiekei (Fuchs, 1970) by the setae on the antennomeres much denser (distinctly sparser in both sexes of these species).

As the separation between Fredlanea and Eulachnesia is still problematic, we think better to compare the new species with some species of the latter. The general appearance of the new species resembles that of Eulachnesia boteroi Monné and Monné, 2015 , but the presence of a distinct humeral carina allows the separation of them (absent in E. boteroi ). Fredlanea lazulina differs from E. cobaltina Bates, 1881 by the humeral carina well-marked (slightly marked in E. cobaltina ) and erect setae dense ventrally on antennomeres (sparser in E. cobaltina ). It differs from E. humilis by the punctures on pronotum finer (coarser in E. cobaltina ) and absence of longitudinal pubescent band in center of pronotum (present in E. cobaltina , but often absent centrally).
