Type material. Holotype male at BMNH labeled: a) “ Peru, Loretto // near Iquitos // Itaya River, 5.ii.2006 // leg A. Petrov // BMNH (E) 2006-123” (Printed, rectangular label with a green printed line 1/3 rd from top)/ b) my handwritten type label.

Type locality. Peru, Loreto, Iquitos, Itaya River.

Description. Holotype male. Length 10.0 mm; width 5.5 mm. Color: Head, pronotum and elytra piceous. Venter and legs piceous to reddish brown. Head: Frons convex, impunctate. Frontoclypeal suture effaced. Clypeus rugopunctate, punctures small. Anterior margin of clypeus with slightly reflexed, attenuate, erect horn, without bead or carina. Pronotum: Surface punctate, a few sparse to moderately dense, large punctures on sides. Basal margin with the occasional puncture. Disc with subtriangular fovea; fovea bordered on each edge by an erect, large, subtriangular, obliquely compressed tumosity. Anterior margin of pronotum with median, subtriangular tubercle. Elytra: Punctures of striae elongate or vermiform, occasionally U- or V-shaped. Striae 1-3 obsolete up to half distance between base and humeral umbone. Lateral margin adjacent to humerus with 11 (right) or 12 (left) setose crenulations. Legs: Protibia with apical denticle. Genitalia: Fig. 61-62 View Figures 50- 64 .

Diagnosis. This species is best identified using the male genitalia ( Fig. 61-62 View Figures 50- 64 ) which are similar in form to the genitalia of A. teamscaraborum ( Fig. 63-64 View Figures 50- 64 ). The lateral and median lobes of the parameres of A. petrovi are subequal in length, but in A. teamscaraborum , the median lobes are longer than the lateral lobes. Females are not known for this species.

Etymology. This species is named in honor of Dr. Alexander Valentinovich Petrov, a specialist on Scolytidae at the Moscow State Forest University in Russia, who collected the holotype.
