Type material. Holotype male from PANAMA, Chiriquí: vic. Chiriquicito , 17.V.1996, Wappes, Huether & Morris leg. ( FSCA, formerly ACMT).

Etymology. The specific epithet “ soniae ” is in honor to our friend, and mentor of the first author, Sonia Aparecida Casari, in recognition of her contributions to the knowledge of Coleoptera , especially on Elateridae and larvae.

Remarks. According to Martins (1965, 1970a, 2009), the upper eye lobes in Neocompsa Martins, 1965 have three rows of ommatidia. However, in N. soniae sp. nov., as well as in some other species of Neocompsa , the upper eye lobes have four rows of ommatidia in the innermost area.

Neocompsa soniae sp. nov. is similar to N. aspasia Martins, 1974 in its general appearance, but differs as follows: upper eye lobes with four rows of ommatidia; antennomeres VII–XI unicolorous; pronotum not abundantly pubescent; and posterior yellow macula on the elytra triangular-shaped. In N. aspasia , the upper eye lobes have three rows of ommatidia, antennomeres VII–XI are bicolorous, pronotum has abundant pubescence not obscuring integument, and the posterior yellow macula on the elytra is longitudinally elongated. The new species can be included in the alternative of couplet “13” from Martins (1970a) (translated, modified):

13(12). Pronotum not pubescent close to posterior margin. Costa Rica, Panama, Colombia, Ecuador, Venezuela, Peru, Bolivia (Santa Cruz), French Guiana, Brazil (Amazonas, Rondônia, Maranhão, Bahia, Espírito Santo, Rio de Janeiro, Paraná)....................................................................................... N. lineolata (Bates, 1870)

- Pronotum with pubescence close to posterior margin..................................................... 13’

13’(13). Upper eye lobes with three rows of ommatidia; antennae in males distinctly shorter than 2.0 times body length. Argentina (Jujuy, Tucumán).............................................................. N. tucumana Martins, 1965

- Upper eye lobes with four rows of ommatidia; antennae in males distinctly longer than 2.0 times body length. Panama....................................................................................... N. soniae sp. nov.

It also can be included in the alternative of couplet “8” from Martins (2009), which leads to the same species:

N. lineolata and N. tucumana .
