Clypeus moderately bilobed, wider than long (4: 1), anterior border shallow and widely sinuated, with margins scarcely elevated, surface convex, with large, round punctures, nearly confluent, with erect, long, slender setae. Fronto­clypeal suture nearly straight and scarcely impressed. Frons wider than long (2.1: 1) convex, with large, round punctures and erect, long, slender setae. Antenna 10 segmented, with 3 segmented club; lamellae slightly longer than length of five preceeding segments combined (1.2:1), segment 4 ° nearly as long as segment 3, segment 5 ° without anterior projections, segments 6 ° and 7 ° wider than long, each one with conical or acute process directed forward. Frons 6.2 × wider than each eye dorsal diameter. Canthus curved and rounded, with 9 setae. Labrum deeply bilobed, with curved, slender setae on all surface. Mentum widely concave, polished, with lateral slender setae, anterior border deeply cleft. Pronotum wider than long (1.8:1) and 2 × wider than frons. Pronotal disk rugo­punctate, punctures separated by one diameter or less, with many erect, long, slender setae; lateral borders widely angulated, marginal bead vaguely crenulate, with long, slender setae; anterior angles slightly obtuse, rounded, scarcely prominent; posterior angles widely obtuse, not prominent. Scutellum 1.6 × wider than long, without punctures. Elytron 2.6 × longer than wide, densely rugo­punctate, with some, scattered, short setae at basal third; epipleural border narrowed, extended along the complete margin, provided with a fringe of medium size setae; humeral calla rounded, prominent; apical calla rounded. Metathoracic wings completely developed. Propygidium shiny, finely punctate with abundant short setae. Pygidium convex, shiny, moderately punctate, with erect, medium size, slender setae near center of disk and short setae toward basal border; preapical area without setae; apical margin with 20 slender setae; basal margin effaced at middle. Pterosternon with long, dense, yellowish vestiture. Visible abdominal sternites 2 ° to 4 ° with narrow and deep mesial sulcus; sternite 5 ° convex, with patch of setiferous granules and posterior border slightly excavated transversally; anal plate wide and shallowly concave, finely granulose­setose, anterior and posterior borders thickened, with scattered erect, long setae on posterior border. Protibiae slightly shorter than protarsi (0.84:1), with two large teeth and one small tooth on external border, preapical spur long, straight, acute, shorter than 2 ° protarsomerus (1.6:2). Mesotibiae with long, slender setae, and one oblique, short, setiferous, transverse carina; upper apical spur straight, narrow, nearly as long as lower spur.

Total body length: 14.1 mm. Humeral width: 6.1 mm.
Paratype Variation. Males are similar to the holotype except in total body length: 11.8–13.5 mm, humeral width: 5.1–5.8 mm. Female paratypes are similar to the allotype except as follows: body color dark reddish brown to dark yellowish brown; pygidium more or less setiferous; total body length: 13.2– 15.1 mm; humeral width: 6.0– 6.5 mm

Type Locality. Las Joyas, Biosphere Reserve Sierra de Manantlán, Autlán municipality, state of Jalisco, México (approx. 19 ° 35 ' 13 " N; 104 ° 16 ' 48 " W).
Biological Data. Specimens of P. manantleca n.sp. were collected at white fluorescent and UV lights in montane cloud forest and pine forest located at 1,900 –2,200 m altitude. They were also collected at Hg vapor lamps in oak forest located at 1,470 –1,650 m altitude, where the dominant tree species is Quercus rugosa Née. Phenology: June (33), July (43), August (276), September (34), October (35), November (9), December (2). Other species of Phyllophaga flying at the same time and place were P. (Phytalus) dugesiana n.sp., P. (Phytalus) jalisciensis n.sp., P. (s.str.) sayloriana n. sp., P. (s.str.) joyana n.sp. and P. (s.str.) chamacayoca Morón.
Remarks. Phyllophaga manantleca n. sp. belong to the species group ‘‘ blanchardi,’’ complex ‘‘ pubicauda ’’ (sensu Morón 1986). The diagnostic combination of characters for both sexes include: anterior border of clypeus widely sinuated; frons and pronotum with dense vestiture of erect, long setae; abdominal sternites 2 ° to 4 ° with deep mesial sulcus; abdominal sternite 5 ° with granulose­setiferous patch; and pygidium finely punctate and moderately setiferous. Shape of paramera is similar to P. inflativentris Moser and P. hintonella Saylor, but the proportions of each part are different.
Etymology. Derived from Sierra de Manantlán, old Aztec name ‘‘ Manauantlan ’’ meaning, ‘‘near the site where defence is developed’’ or ‘‘near defended site,’’ ‘‘near fortification’’ (Manauia = defended, ana = growth, development, tlan = near) Simeón (1988).
