Akamboja monteirorum sp. nov. Roza, Quintino, Mermudes & Silveira

( Figs 27–30 View FIGURES 23 – 30 and 43 View FIGURES 41 – 43 )

Etymology. The name is in honor to the Monteiro family, especially our dear friends, Drs. Ricardo and Margarete. Their enthusiasm and contributions to Neotropical insect ecology are noteworthy. They also helped the last author to collect specimens of three species. Genitive, plural.

Diagnosis. Male.

Eyes occupying two thirds of head width, in lateral view ( Fig. 29 View FIGURES 23 – 30 ). Apical maxillary palpomere 3.5x longer than subapical ( Fig. 29 View FIGURES 23 – 30 ). Vertex occupying? of head in dorsal view ( Fig. 30 View FIGURES 23 – 30 ). Elytron reaching the posterior margin of the fourth abdominal segment ( Fig. 27 View FIGURES 23 – 30 ).

Description, male.

Measurements (n=5): Total length: 4.1–4.5 mm (aver. 4.3 mm). Head length: 0.5–0.7 mm (aver. 0.6 mm). Head width: 0.6–0.7 mm (aver. 0.6 mm). Pronotum length: 0.5–0.6 mm (aver. 0.55 mm). Pronotum maximum length: 0.5–0.6 mm (aver. 0.55 mm). Elytron length: 1.5–1.6 mm (aver. 1.55 mm). Elytron maximum width: 0.4 mm (aver. 0.4 mm). Elytral spot length: 0.2–0.3 mm (aver. 0.25 mm).

Morphology: Eyes occupying two thirds of head width, in lateral view ( Fig. 29 View FIGURES 23 – 30 ). Vertex occupying? of head in dorsal view ( Fig. 30 View FIGURES 23 – 30 ). Apical maxillary palpomere 3.5x longer than subapical ( Fig. 30 View FIGURES 23 – 30 ). Head as wide as long ( Fig. 30 View FIGURES 23 – 30 ). Elytron 3.5x longer than wide ( Fig. 27 View FIGURES 23 – 30 ), reaching the posterior margin of the fourth abdominal segment, elytron apical spot occupying a fifth of the elytron ( Fig. 27 View FIGURES 23 – 30 ).

Color. Body overall light brown. Pronotum dark to light brown. Elytron almost black to light brown, apex pale yellow, sometimes light brown. Wing venation black to light brown.

Immature and females. Unknown

Biology and distribution. Akamboja monteirorum sp. nov. seems to occur only during spring and summer. It inhabits high altitudinal areas of Itatiaia, on the Itatiaia massif, in the Serra da Mantiqueira mountain range, from 1280 to 1442 m. It is found on the montane forest.

Remarks. This species resembles Akamboja minimum sp. nov., but can be distinguished by its bigger size, elytron (the elytron of Akamboja minimum sp. nov. reaches the anterior margin of the second abdominal segment, while in Akamboja monteirorum sp. nov. it reaches the posterior margin of the third), smaller vertex (bigger in Akamboja minimum sp. nov.) and its high altitude occurrence (low altitude occurrence in Akamboja minimun sp. nov.). Akamboja monteirorum sp. nov. occurs only in montane forest (from 830 m to 1442 m), while Akamboja minimum sp. nov. occurs in lower montane forest (below 800 m) and partially in the montane forest (beginning in 600 m).
