Defendant-Appellant Luis Alberto Villa-Delgado appeals the 46-month sentence imposed following his guilty-plea conviction for attempting to reenter the United States illegally after having been removed. He contends that the district court erred in ruling that his prior Idaho rape conviction constituted the enumerated offense of statutory rape, triggering the 16-level enhancement contained in U.S.S.G. § 2L1.2(b)(l)(A)(ii). He also contends that *252 his sentence exceeds the statutory maximum under 8 U.S.C. § 1326(a).

As Villa preserved his Guidelines argument in the district court, we review that court’s interpretation of the Guidelines de novo. United States v. Carbajal-Diaz, 508 F.3d 804, 807 (5th Cir. 2007). The Idaho statute of conviction criminalizes sexual intercourse with a female younger than 18 years of age. The charging document, to which Villa pleaded guilty, stated that the female victim was 13 years of age. Thus, Villa’s crime may be narrowly defined as unlawful sexual intercourse with a 13-year old female. See id. at 807-10. This crime is encompassed within the generic, contemporary meaning of statutory rape. Accordingly, application of the 16-level enhancement was proper. See id.

Relying on Apprendi v. New Jersey, 530 U.S. 466, 120 S.Ct. 2348, 147 L.Ed.2d 435 (2000), Villa challenges the constitutionality of § 1326(b)’s treatment of prior felony and aggravated felony convictions as sentencing factors rather than elements of the offense that must be found by a jury. This challenge is foreclosed by Almendarez-Torres v. United States, 523 U.S. 224, 235, 118 S.Ct. 1219, 140 L.Ed.2d 350 (1998). United States v. Pineda-Arrellano, 492 F.3d 624, 625 (5th Cir. 2007), cert. denied, — U.S.-, 128 S.Ct. 872, 169 L.Ed.2d 737 (2008).

AFFIRMED.
