Integument mostly dark reddish brown; parts of ventral mouthparts and apex of palpomeres yellowish brown; base of pedicel and carinae on antennomeres III–VI dark brown; antennomeres VI–XI orangish brown, gradually lighter toward XI. Elytra with two yellow maculae dorsally, one longitudinal from about basal ninth to middle, another oblique, subtriangular, placed slightly after middle; area between yellow maculae slightly darker than laterally, especially on central region, and apical fourth of elytra gradually lighter. Posterocentral area of mesoventrite and mesoventral process light reddish brown, except narrow dark brown margins close to mesocoxae. Tibiae light orangish brown from middle.

Antennal tubercles smooth and glabrous, except for a few fine punctures, with short, sparse whitish setae centrally; elevated and abruptly inclined posteriorly. Central area between antennal tubercles smooth and glabrous. Region between posterior margin of eyes and prothorax smooth, glabrous about middle; sides of this region finely, somewhat abundantly punctate; with sparse whitish pubescence, and a few long, erect yellowish-brown setae close to eyes; area close to prothorax slightly rugose-punctate, glabrous. Area behind upper eye lobes finely, somewhat abundantly punctate, with abundant whitish pubescence not obscuring integument, except finely rugose-punctate, glabrous narrow area close to prothorax.

Scape slightly widened toward apex, not sulcate dorsally; finely sparsely punctate, except smooth dorsal apex; with sparse, decumbent whitish setae and a few long, erect yellowish-brown setae, except glabrous smooth area. Pedicel finely, abundantly punctate; with short, decumbent, sparse whitish setae and a few long erect yellowish-brown setae.

Thorax. Prothorax cylindrical, distinctly longer than wide; sides slightly narrowed close to posterior sixth, slightly widened from middle to posterior constriction. Pronotum not tuberculate; finely, sparsely punctate; central region almost smooth, except slightly transversely striate area close to anterior margin; with short, decumbent, very sparse whitish setae and a few long, erect yellowish-brown setae, except posterior seventh with abundant yellowishbrown pubescence, almost absent centrally and gradually yellower toward sides. Sides of prothorax finely, sparsely punctate; with wide, longitudinal yellowish-white pubescent band near prosternum, following the pubescent apical band on pronotum, and not reaching anterior margin; remaining surface with short, decumbent, very sparse whitish setae. Prosternum finely, very sparsely punctate on posterior half, slightly transversely striate on anterior half; with a few short, decumbent whitish setae, distinctly more abundant, yellowish-white close to procoxal cavities.

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.
