Chrysaperda mimica sp. nov. ( Fig. 1 )

Male. Head with integument black and shining in occiput and superior half of frons between upper lobes of eyes; genae and inferior half of frons clear yellow with scarce short erect hairs. Antennae with integument of scape pale yellow, antennomeres II, III black; IV to VI whitish, VII to XI blackish. Thorax and elytra reddish-brown, abdomen and legs pale yellow.

Frons concave between eyes; upper lobe connected to lower lobe by 2–3 rows of facets at narrowest point; lower lobe much larger than upper lobe, as high as yellow part of genae below. Antennae slender, extending beyond elytral apices by one antennomere. Scape slightly recurved and dilated to apex; antennomere III two times length of IV; antennomeres VII to XI greatly reduced in length. Antennomeres with short and sparse pubescence on ventral side.

Prothorax cylindrical, distinctly narrower than elytral base, with slight lateral protuberance at middle. Pronotum with a median callus, very slightly projected; 1–2 rows of punctures along anterior and posterior margins. Prosternal process narrow, less than one third width of procoxae. Mesosternal process approximately 2/3 width of a mesocoxa.

Elytron with humerus strongly projecting posterolaterally, lateral carinae clearly delimitated from humerus to apex. Apex subrounded, with a minute spicule in marginal side. Punctures minute and dense at anterior half, becoming shallower and sparse at distal third. Yellowish sparse pubescence more dense in distal third. Legs with femora and tibiae sublinear; metafemora extending to third urosternite. Apex of urotergite and urosternite transversely truncate. Etymology. The specific epithet is a Latin adjective, feminine gender, meaning imitator, and refers to the appearance of an insect of the Chrysomelidae subfamily Galerucinae .

Measurements (mm), male. Total length, 9.0–10.5; prothorax length, 1.3–2.2; prothorax width, 1.8–2.5; elytral length, 6.4–7.8; humeral width, 2.8–3.5.

Type material. Holotype male, ECUADOR, Morona-Santiago: Macas, 1300m, 11.VIII.1990, M. Cooper leg. ( BMNH). Paratypes: male, same locality and collector, 14.VIII.1990 ( BMNH); male, 28.VII.1993 ( MNRJ).

Remarks. Martins & Galileo (2014b) lists four species of Chrysaperda , two of them known from Ecuador, one from Ecuador and Peru and one from Brazil (Amazonas). C. mimica sp. nov. can be distinguished from the four species by the unicolorous, reddish-brown elytra. In all the other species of Chrysaperda , the elytra are black or metallic blue, with a transverse yellow fascia at the apex.
