( Figs 36–40 View FIGURES 31 – 40 and 45 View FIGURES 44 – 45 )

Etymology. The name is in reference to the Serra do Caparaó, location of occurrence of the species. Name in apposition.

Diagnosis. Pronotum dark brown. Eyes occupying half of head width, in lateral view ( Fig. 38 View FIGURES 31 – 40 ). Vertex occupying ½ of head in dorsal view ( Fig. 40 View FIGURES 31 – 40 ). Apical maxillary palpomere 3.5x longer than subapical ( Fig. 38 View FIGURES 31 – 40 ). Elytron reaching the anterior margin of the third abdominal segment ( Fig. 36 View FIGURES 31 – 40 ).

Description, male.

Measurements (n=1): Total length: 4.7 mm. Head length: 0.65 mm. Head width: 0.61 mm. Pronotum length: 0.63 mm. Pronotum maximum width: 0.6 mm. Elytron length: 1.7 mm. Elytron maximum width: 0.4 mm. Elytral spot length: 0.3 mm.

Morphology: Eyes occupying half of head width, in lateral view ( Fig. 38 View FIGURES 31 – 40 ). Lateral region of the head sparsely setose posterior to eyes ( Fig. 39 View FIGURES 31 – 40 ).

Elytron 4x longer than wide ( Fig. 36 View FIGURES 31 – 40 ), Elytron reaching the anterior margin of the third abdominal segment ( Fig. 36 View FIGURES 31 – 40 ), apical spot occupying a fifth of the elytron ( Fig. 36 View FIGURES 31 – 40 ).

Coloration. Body overall dark brown. Pronotum dark brown. Elytron dark brown, apex pale yellow. Wing venation black.

Biology and distribution. Akamboja caparaoensis   sp. nov. seems to occur only on summer, although this can be an artifact due to the low number of specimens. It inhabits high altitudinal areas of Dores do Rio Preto, on the Serra do Caparaó, in the Serra da Mantiqueira mountain range, around 1500 m. It is found on dense ombrophilous high montane forest.

Remarks. This species resembles Akamboja tenebrae   sp. nov., but can be distinguished mainly due to its bigger size and elytron (the elytron of Akamboja tenebrae   sp. nov. reaches the anterior margin of the second abdominal segment, while in Akamboja caparaoensis   sp. nov. it reaches the anterior margin of the third), head more densely setose behind the eyes (sparsely setose in Akamboja caparaoensis   sp. nov.), smaller vertex (bigger in Akamboja caparaoensis   sp. nov.) and its higher altitude occurrence (lower altitude occurrence in Akamboja tenebrae   sp. nov.).

Type material. Holotype (male): BRAZIL. Espírito Santo: Dores do Rio Preto. Parque Nacional do Caparaó, afluente do Rio Preto ( Laje ), 20°29’26,2’’S, 41°49’17,1’’W, 1567m, Malaise, 1 male, 11–15.I.2015, J. L. Nessimian, A. L. H. Oliveira, S. P. Gomes and C. P. Souza col ( DZRJ). GoogleMaps
