We are asked to decide whether a defendant’s prior California conviction for unlawful sexual intercourse with a minor qualifies as a “crime of violence” under the federal Sentencing Guidelines.
I
On March 1, 2005, a U.S. Border Patrol agent found Alejandro Gomez-Mendez near the San Ysidro, California, Port of Entry. Gomez-Mendez was arrested after admitting that he was a citizen and national of Mexico and present in the United States without any documents permitting him to enter the United States legally. A grand jury returned a one-count indictment charging Gomez-Mendez with being a deported alien found in the United States in violation of 8 U.S.C. § 1326. Gomez-Mendez pled guilty to the charge without the benefit of a plea agreement.
The probation officer filed a presentence report, which indicated that the maximum term of imprisonment was twenty years and recommended a sentence of ninety-four months. The presentence report computed the base offense level as eight *601 and concluded that a sixteen-level sentencing enhancement pursuant to U.S.S.G. § 2L1.2(b)(1)(A)(ii) was appropriate because of Gomez-Mendez’s 2002 conviction for felony unlawful sexual intercourse with a minor under age sixteen by a person twenty-one years of age or older, in violation of CaLPenal Code § 261.5(d). The presentence report further recommended a two-level downward adjustment for acceptance of responsibility pursuant to U.S.S.G. § 3El.l(a), but recommended against the extra one-level reduction for acceptance of responsibility pursuant to U.S.S.G. § 3El.l(b) because the government failed to file the required motion.
Gomez-Mendez objected to the report’s recommended sentence, arguing that the maximum statutory penalty was only two years imprisonment and one year of supervised release, because the California conviction was neither alleged in the indictment nor admitted at the plea colloquy. He also argued that a sixteen-level enhancement was inappropriate because his prior California conviction did not categorically qualify as a “crime of violence.” Finally, Gomez-Mendez claimed that a three-level downward adjustment for acceptance of responsibility was appropriate because the government had no good faith basis for not filing the motion required for the additional one-level adjustment under U.S.S.G. § 3El.l(b).
The district court refused to decide whether the government improperly declined to file the motion required for the extra one-level downward adjustment for acceptance of responsibility. 1 The district court sentenced Gomez-Mendez to eighty-four months in custody, three years of supervised release, and a $100 penalty. The sentence included a sixteen-level enhancement under U.S.S.G. § 2L1.2(b)(l)(A)(ii) for the prior felony conviction under Cal.Penal Code § 261.5(d). The sentence also reflected a two-level downward adjustment for acceptance of responsibility pursuant to U.S.S.G. § 3El.l(a).
Gomez-Mendez appeals.
II
We consider as a matter of first impression Gomez-Mendez’s argument that the district court erred in holding that his prior conviction under CaLPenal Code § 261.5(d) was a “crime of violence.”
A
Section 2L1.2(b)(1)(A)(ii) of the U.S. Sentencing Guidelines provides for a sixteen-level sentencing enhancement upon conviction under 8 U.S.C. § 1326, where an alien illegally reentered the United States after having been previously deported subsequent to a conviction for a felony “crime of violence.” 2 The Sentenc *602 ing Guidelines fail to define a “crime of violence” for such purposes. The Commission’s commentary, however, defines a “crime of violence” to mean any of the following: “murder, manslaughter, kidnapping, aggravated assault, forcible sex offenses, statutory rape, sexual abuse of a minor, robbery, arson, extortion, extortionate extension of credit, burglary of a dwelling, or any offense under federal, state, or local law that has as an element the use, attempted use, or threatened used of physical force against the person of another.” U.S.S.G. § 2L1.2 cmt. n. l(B)(iii) (emphasis added). 3

To determine whether a conviction constitutes “statutory rape” and therefore a “crime of violence,” we employ the familiar categorical approach the Supreme Court crafted in
Taylor v. United States,
Section 261.5(d) of the California Penal Code, the offense at issue in this case, provides:
Any person 21 years of age or older who engages in an act of unlawful sexual intercourse with a minor who is under 16 years of age is guilty of either a misdemeanor or a felony, and shall be *603 punished by imprisonment in a county jail not exceeding one year, or by imprisonment in the state prison for two, three, or four years.
Cal.Penal Code § 261.5(d). This section is considered California’s statutory rape law.
See Michael M. v. Superior Court,
The term “statutory rape” is ordinarily, contemporarily, and commonly understood to mean the unlawful sexual intercourse with a minor under the age of consent specified by state statute.
7
This meaning of “statutory rape” covers the full range of conduct proscribed by Cal.Penal Code § 261.5(d). Moreover, we have recognized that the commentary to U.S.S.G. § 2L1.2 “lists statutory rape as per se a crime of violence.”
Valencia v. Gonzales,
2
Gomez^-Mendez nevertheless argues that a conviction under CaLPenal Code § 261.5(d) is overbroad under the categorical approach because, according to Gomez-Mendez, unlike “a large number of states” and the Model Penal Code, the reasonable belief that the victim was over the age of sixteen is no defense to statutory rape in California.
8
Under California case law, a reasonable belief that the victim was eighteen or older, the age of consent established by Cal.Penal Code § 261.5(a),
is
a defense,
see People v. Hernandez,
This difference is of no consequence.
Taylor
stands for the proposition that a state crime must include all of the
elements
of the generic federal crime.
See Asberry,
3
Gomez-Mendez further contends that CaLPenal Code § 261.5(d) is overbroad under the categorical approach because “promiscuity” or “unchaste character” provides no defense to statutory rape in California. Gomez-Mendez’s only authority for this assertion is Model Penal Code § 213.6(3), which continues in spite of sharp criticism to promote a promiscuity defense. He cites no jurisdiction, and we are aware of none, that retains a promiscuity defense to a charge of statutory rape.
4
Gomez-Mendez also argues that Cal.Pe-nal Code § 261.5(d) is overbroad according to our decision in
Corona-Sanchez,
Like all other states and the federal government, California has expressly abrogated the common law distinction among principals, “aiders and abettors present at the scene of the crime” (i.e., second-degree principals), and “aiders and abettors who helped the principal before the basic criminal event took place” (i.e., accessories
before
the fact).
Gonzales v. Duenas-Alva
rez,-U.S.-,-,
Gomez-Mendez’s reliance on
Coronar-Sanchez,
however, is misplaced because
*605
that case was decided under Sentencing Guidelines that have since been amended. Unlike the 1997 version of U.S.S.G. § 2L1.2 we construed in
Carona-Sanehez,
the amended version of the application notes accompanying that section now expressly provide that “[p]rior convictions of offenses counted under Subsection (b)(1) include the offenses of aiding and abetting, conspiring, and attempting, to commit such offenses.” U.S.S.G. § 2L1.2 cmt. n. 5;
see also Guerrero-Velasquez,
Finally, a conviction for statutory rape under § 261.5(d) does not run afoul of our decision in
United States v. Innie,
HI
There is one other related sentencing issue to be resolved. Gomez-Mendez claims that the district court erred by increasing his sentence based on a prior conviction that was not alleged in the indictment, proven beyond a reasonable doubt to a jury, or admitted at the time of the guilty plea. Aliens who return to the United States after removal and without permission.are subject to two years incarceration pursuant to 8 U.S.C. § 1326(a). Under 8 U.S.C. § 1326(b)(2), a prison term of up to twenty years may be imposed for aliens “whose [prior] removal was subsequent to a conviction for commission of an aggravated felony.” In
Almendarez-Torres v. United States,
Gomez-Mendez asserts that according to principles of statutory construction, a prior conviction is an element of the offense under the current version of 8 U.S.C. § 1326(b)(2), rather than a sentencing factor, because a 1996 amendment changed the structure of that section and added a title to subsection (b). But 8 U.S.C. § 1326(b)(2), the provision considered in
Almendarez-Torres
and at issue in this
*606
case, remains virtually unchanged after the 1996 amendment.
9
We do not believe that the 1996 amendment transformed subsection (b)(2) from a sentencing factor, as the Supreme Court held in
Almenda-rez-Torres,
to a new criminal offense, as Gomez-Mendez claims, simply because that amendment modified the title of subsection (b) and added subsections (b)(3) and (b)(4). In the pith of his claim, Gomez-Mendez essentially argues that we are no longer bound by the Supreme Court’s holding in
Almendarez-Torres,
because it interpreted a prior version of 8 U.S.C. § 1326. We have repeatedly rejected the argument that
Almendarez-Torres
is no longer good law and have held that the current version of 8 U.S.C. § 1326(b)(2) constitutes a sentencing factor under
Almendarez-Torres. See, e.g., United States v. Ochoa-Gaytan,
IV
Finally, we consider Gomez-Mendez’s argument that the district court erred in failing to apply an additional one level reduction for timely acceptance of responsibility under U.S.S.G. § 3El.l(b)
11
*607
because the government improperly refused to file a motion under that provision. The district court expressly refused to make a finding whether the government improperly declined to file the motion. We have recently held that the government cannot refuse to file a motion under this provision “on the basis of an unconstitutional motive (e.g., racial discrimination), or arbitrarily (i.e., for reasons not rationally related to any legitimate governmental interest).”
Espinozar-Cano,
V
Thus, we affirm the district court’s determination that Gomez-Mendez’s prior conviction for unlawful sexual intercourse by a person at least twenty-one years old with a minor under sixteen years old under CaLPenal Code § 261.5(d) qualifies as a “crime of violence” under U.S.S.G. § 2L1.2(b)(l)(A)(ii). We further conclude that the district court did not err in increasing Gomez-Mendez’s sentence under 8 U.S.C. § 1326(b)(2). We remand this case to the district court for further proceedings to determine whether the government improperly refused to file a motion under U.S.S.G. § 3El.l(b).
AFFIRMED IN PART AND REMANDED IN PART.
Notes
. The district court and the parties framed the inquiry as whether the government violated an "abuse of discretion” standard. As discussed below, we have recently held that the proper inquiry is whether the government acted “on the basis of an unconstitutional motive (e.g., racial discrimination), or arbitrarily (i.e., for reasons not rationally related to any legitimate governmental interest).”
United States v. Espinoza-Cano,
. While the Sentencing Guidelines are now advisory,
see United States v. Booker,
. "Commentary to the Guidelines binds us in interpreting their provisions unless it violates the Constitution or federal statute, or is inconsistent with the Guidelines.”
United States v. Asberry,
. Although we have suggested that statutory rape is an extension of the common law crime of forcible rape and that the offense is old enough to be considered part of the common law in the United States despite its statutory heritage,
see United States v. Brooks,
.If the offense fails to qualify as a "crime of violence” under the categorical approach, we may "go beyond the mere fact of conviction” and consider "documentation of judicially noticeable facts that clearly establish the conviction is a predicate conviction for enhancement purposes.”
United States v. Rivera-Sanchez,
. Although Cal.Penal Code § 261.5 is titled "Unlawful Sexual Intercourse,” "[w]e look solely to the statutory definition of the crime, not to any name given to the offense.”
United States v. Baron-Medina,
.
See
Black’s Law Dictionary 1288 (8th ed.2004) (defining “statutory rape” as "[u]n-lawful sexual intercourse with a person under the age of consent (as defined by statute), regardless of whether it is against that person's will”);
see also
Susan M. Kole, Annotation,
Statute Protecting Minors in a Specified Age Range from Rape or Other Sexual Activity as Applicable to Defendant Minor Within Protected Age Group,
. A mistake-of-age defense to statutory rape is the minority rule in the United States.
See
Colin Campbell, Annotation,
Mistake or Lack of Information as to Victim's Age as Defense to Statutory Rape,
. The 1996 amendment to subsection (b)(2) simply replaced the term "deportation” with "removal” to reflect new terminology introduced by Illegal Immigration Reform and Immigrant Responsibility Act, Pub.L. No. 104-208, § 309(d)(2), 110 Stat. 3009, 3009-627 (1996). We have held that "any distinction between deportation and removal is legally insignificant for purposes of § 1326.”
United States v. Lopez-Gonzalez,
. Gomez-Mendez filed a letter of supplemental authorities under Fed. R.App. 28(j) contending that the district court committed
Apprendi
error by enhancing his sentence based on his prior removal, a fact which was never admitted nor proven to a juty beyond a reasonable doubt.
See United States v. Covian-Sandoval,
Moreover, an issue raised for the first time in a letter of supplemental authorities under Fed. R.App. 28(j) is ordinarily deemed waived.
See, e.g., Pawlyk v. Wood,
.U.S.S.G. § 3El.l(a) requires a sentencing court to reduce by two levels the offense level of a defendant who "clearly demonstrates acceptance of responsibility for his offense.” Under U.S.S.G. § 3El.l(b), a defendant whose offense level is 16 or greater prior to the adjustment authorized by U.S.S.G. § 3El.l(a) could receive an additional one-level reduction "upon motion of the government stating that the defendant has assisted *607 authorities ... by timely notifying authorities of his intention to enter a plea of guilty, thereby permitting the government to avoid preparing for trial and permitting the government and the court to allocate their resources efficiently.”
