Filed August 9, 2017

Madina Buhendwa, Pro Se

Jonathan Saadeh, Regional Transportation District, Denver, CO, for Defendant-Appellee

Before LUCERO, BALDOCK, and MORITZ, Circuit Judges.

*665ORDER AND JUDGMENT *

Nancy L. Moritz, Circuit Judge

Madina Buhendwa, proceeding pro se,1 appeals the district court’s order dismissing her complaint as duplicative of a previous action. We affirm.

For many years, and in multiple lawsuits, Buhendwa has unsuccessfully sought to recover against the Regional Transportation District (RTD) for injuries she allegedly sustained during bus accidents. *See Buhendwa v. Reg’l Transp. Dist.,*553 Fed. Appx. 768, 769-70 (10th Cir. 2014) (unpublished). In 2014, we affirmed the dismissal of Buhendwa’s first federal action because she failed to state a claim on which relief could be granted. *See id.*at 771. Two months later, Buhendwa brought a new action against RTD that presented claims identical to those in her first action.

The district court dismissed that second action, concluding that res judicata barred Buhendwa from litigating her previously dismissed claims. Buhendwa moved for post-judgment relief in the. form of an independent action, or, alternatively, under Federal Rule of Civil Procedure 60. Bu-hendwa asserted that RTD (or its counsel) had defrauded the court in order to obtain dismissal. But before the district court ruled on that motion, Buhendwa filed her complaint in the present action.2' The complaint is essentially identical to her motion for post-judgment relief in the second action.

The district court dismissed the present action, concluding that Buhendwa failed to explain “why the current case is not dupli-cative of her previous case.” R. 95. Bu-hendwa appeals that dismissal,3 and we review for abuse of discretion. *See Hartsel Springs Ranch of Colo., Inc. v. Bluegreen Corp.,*296 F.3d 982, 985 (10th Cir. 2002).

We’ve previously held that a district court may dismiss a suit “for reasons of wise judicial administration ... whenever it is duplicative of a parallel action already-pending in another federal court.” *Id.*(alteration in original) (quoting *Serlin v. Arthur Andersen & Co.,*3 F.3d 221, 223 (7th Cir. 1993)). But here, the district court didn’t expressly analyze whether Buhend-wa’s second action was ./‘pending,” as our precedent seems to require. *Id.*

Nevertheless, Buhendwa doesn’t argue that the district court erred in dismissing her action as duplicative of a non-pending parallel action. Indeed, Buhendwa fails to raise *any*articulable challenge to the district court’s reasoning. *See United States v. Apperson,*441 F.3d 1162, 1195 (10th Cir. 2006) (explaining that appellant “fail[ed] to *666offer any detailed explanation of how the district court erred” and thus “failed to sufficiently place [its] rulings at issue”); *Garrett,*425 F.3d at 841 (noting that even pro se appellant’s brief “must contain ... more than a generalized assertion of error, with citations to supporting authority” (alteration in original) (quoting *Anderson v. Hardman,*241 F.3d. 544, 545 (7th Cir. 2001))). We therefore affirm.

As a final matter, we deny Buhendwa’s motion to proceed on appeal in forma pau-peris.

*

 After examining the briefs and appellate record, this panel has determined unanimously that oral argument wouldn't materially assist in the determination of this appeal. *See*Fed. R. App. P. 34(a)(2); 10th Cir. R. 34.1(G). The case is therefore ordered submitted without oral argument. This order and judgment isn’t binding precedent, except under the doctrines of law of the case, res judicata, and collateral estoppel. But it may be cited for its persuasive value. *See*Fed. R. App. P. 32.1; 10th Cir. R. 32.1.

. We liberally construe pro se pleadings. But we don’t act as an advocate for pro se litigants. *Garrett v. Selby Connor Maddux & Janer,*425 F.3d 836, 840 (10th Cir. 2005).

2

. While Buhendwa’s motion for post-judgment relief was pending, she also sought a writ of mandamus from this court. We denied her petition, noting that a direct appeal would be the appropriate vehicle for seeking our review.

3

. We reject RTD’s assertion that Buhendwa’s appeal is untimely. RTD wrongly bases its calculation on the district court’s initial dismissal order, rather than on the district court’s subsequent denial of Buhendwa’s motion under Federal Rule of Civil Procedure 59. *See*Fed. R. App. P. 4(a)(4)(A)(iv) (noting that time to file notice of appeal runs from disposition of timely Rule 59 motion).
