Diagnosis. The new species is closely related to Premnophilus pedrosai and P. sarahsmithiae but can be distinguished by the absence of large granules on interstria 1 and the less abundant vestiture on the elytral disc.

Female. Total length: 1.45–1.72 mm, maximum width: 0.50–0.67, length of elytra: 0.81–1.05 mm, total length / width: 2.56–2.86, elytra length / total length: 1.36–1.69, pronotal length / width: 1.1–1.3, (n=3). Color reddish brown to dark brown.

Frons reticulate, with large, shallow punctures, epistomal margin granulate. A weakly elevated, longitudinal carina runs from well above the eyes to central part of frons. Vestiture of short sparse pale hairs, longer and abundant in epistomal margin above mandibles. Gena glabrous. Eyes shallowly emarginate, 2.2 as long as wide. Antenna brown. First segment of anterior face of antennal club corneus, middle portion reaching about middle length of club.

Pronotum reddish brown to dark brown in anterior part. Base and anterior margins of pronotum rounded, lateral margins subparallel in 1/2 of pronotal length. Asperities on its leading edge small, same size those on the rest of the anterior slope. Summit anterior to the middle of disc. Pronotal disc dull, faintly reticulate; punctures shallow, small, widely spaced. Sparse erect short pale setae on disc, more abundant long erect setae on anterior slope and lateral margins of pronotal base. Scutellum small, rounded, glabrous, dark brown.

Elytral disc weakly shining, smooth. Sides subparallel from base to declivity; disc occupying basal 62–69 % of elytral length. Striae not impressed, punctures shallow, with short erect setae. Interstriae wider than striae with mostly uniseriate short erect setae, their length less than interstrial width. All interstriae becoming granulate at the base of the declivity. Declivity occupying 31–38% of declivital length in lateral view; weakly sulcate near the base. Interstria 1 raised along suture with a uniseriate row of small granules from the base to the apex. Granules on interstria 1 equal to granules on all surface of declivital disc. Entire declivital disc covered by abundant long adjacent yellow setae. Anterior margin and lateral areas of declivity with erect setae. Elytral anterior margin bilobed.

Metasternum and metepisternum reddish brown with long pale setae. Abdomen dark brown, ventrites with rows of long pale setae. Legs brown, unicolored, covered by short yellow hairs.

Male. Unknown.

Type Material. Holotype, female, Peru: Loreto region, left river bank of Amazon, 60km SW Iquitos, Rio Itaya , 0415′28.1′′S 7327′59.3′′W, h~ 130 m, 1-II-2006, window trap, A.V. Petrov leg. ( ZMM) . Paratypes, females: as holotype ( APP, 2) ; Junin region, 15 km NW Satipo, near Rio Venado village , 1111′35.2′′S 7446′07.0′′W, h~ 1300 m, 1-3-X-2015, window trap ( APP, 1) .

Distribution. Known from tropical rain forest of Amazonas (bosque de colina baja) and subtropical forest of (Bosque montano de Yunga) ( Fig. 12F ).

Etymology. This species is named in honor of the taxonomist Dr. Bjarte H. Jordal (Bergen, Norway) for his notable contributions to the systematics of the Scolytinae .
