Phyllophaga (Cnemarachis) perfidia Smith and Paulsen , new species

( Figs. 39–42 )

Type Series. Holotype, allotype, 25 paratypes. 22 males (10 CMNC [including holotype], 1 MNHC, 8 UNSM. 3 USNM), 3 females (1 allotype CMNC, 1 UNSM, 1 USNM) labeled: “ CUBA: Cienfuegos Prov. / Res. Ecológica Pico San Juan / 21.97083°N, 80.11859°W / 856 m; MV lights; forest edge / 18-V- 2013; A.B.T.Smith ”. 2 females (1 CMNC, 1 UNSM) labeled: “ CUBA: Cienfuegos Prov. / east of Cuatro Vientos / 21.94596°N, 80.05318°W / 780 m; MV light; 19-V-2013 / A.B.T.Smith, F.Cala-Riquelme ”.

Diagnosis. Elytra pruinose ( Figs. 39–40 ); clypeus strongly sinuate; antennal club much shorter than funicle and scape; pronotal lateral margin entire; prosternum with two spines basal to procoxae; metasternum glabrous; abdominal sternite 5 opaque/ pruinose laterally, glabrous medially; pygidium disc glabrous; male genitalia distinct as in Fig. 41 .

Holotype Description. Length 11 mm, width 6 mm. Dorsal surface shiny, dark brown with purplish gray, pruinose reflections on elytra (small patch on apical umbone of elytra without pruinosity) ( Fig. 39 ). Head and pronotum without pruinosity. Head: Surface moderately punctate with deep, welldefined punctures; glabrous. Clypeus with apex reflexed, sinuate with middle distinctly shorter than sides. Frontoclypeal suture well-defined by line and punctures, clypeus and frons in same plane. Antennae with 9 antennomeres; club slightly less than half length of funicle and scape; club, funicle, scape shiny. Pronotum: Surface moderately punctate with deep, well-defined punctures; glabrous. Apical angles moderately acute; lateral margins entire (not crenulate), widest medially. Elytra: Surface moderately punctate with deep, welldefined punctures; largely glabrous but with some scattered setae, especially near apex. Striae poorly defined, obscure. Legs: Protibia with 3 teeth, 2 nd tooth distinctly closer to apical tooth. Meso- and metatibia without medial carinae, with spines on lateral margin. Metatibial spurs unmodified, shorter spur more than 3/4 length of longer spur. Claws symmetrical with medial triangular tooth, apex unmodified. Venter: Prosternum with 2 spines behind procoxae. Metasternum glabrous (except for a few scattered setae adjacent to midline), medially shiny and laterally with opaque/pruinose coating. Abdominal sternites medially shiny and laterally with opaque/pruinose coating. Pygidium: Surface moderately punctate with large, welldefined punctures; glabrous; shiny except with opaque/pruinose coating along margin of base. Male genitalia: As in Fig. 41 .

Variation. Male length 11–12 mm, width 6 mm; female length 11 mm, width 6 mm. Males with small, slit-like patch of shiny non-pruinosity near apex of elytra ( Fig. 39 ); females with a much larger patch extending 1/4–1/3 length of elytra ( Fig. 40 ). Terminal abdominal segment longer and more inflated in females than in males. One male specimen light brown dorsally with a round, reduced labium exposing much of the mandibles; labium on all other specimens thickened, inverted U-shaped.

Etymology. This species is named for its deceptive external appearance - perfidia meaning “treachery” in Latin. This species externally looks like several other Cuban species. This name is a noun in apposition.

Distribution ( Fig. 42 ). CUBA: Cienfuegos: Reserva Ecológica Pico San Juan, 21.97083°N, 80.11859°W (25); east of Cuatro Vientos 21.94596°N, 80.05318°W (2).

Temporal Data. May (27).

Remarks. This species keys to couplet 23 in Chapin (1932) but does not match the description or genitalic illustrations of P. cardini or P. speculifera .
