Type material. Holotype male ( JBB 011): Philippines, Luzon, Ilocos Norte, Adams, Mt. Pau, secondary forest, (18.45, 120.866), day, rainy, col. J. B. Baroga, S. A. Yap, V. Yngente & W. Bulalacao, 30.xi–2.xii-2013, molecular sample N18PaPau1 (UPLBMNH ORT-01097).

Type locality. Philippines, Luzon, Ilocos Norte, Adams, Mt. Pau.

Distribution. Philippines, northern Luzon, Adams, Ilocos Norte.

Etymology. The name of the species comes from the Latin word “septentrionarius” which means “northern”, referring to the fact that the species is the first Paranisitra found in the northern part of Luzon.

Diagnosis. Paranisitra septentria is close to P. longipes Chopard, 1925 and P. leytensis Robillard, 2015 , from which it differs by not having a transverse yellow band on face. P. s ep t e n t r i a is characterized by its face and mouthparts entirely dark brown, with yellow maxillary palpi. Male genitalia with membranous lophi, ectophallic fold with strong leaf-like lateral sclerites (rounded in P. leytensis ).

Description. Species size typical of the genus ( Figs. 5 , 6 ). Coloration yellow brown mottled with dark markings except fore and median legs, with less or no markings. Vertex homogeneously black ( Fig. 6 ). Region of head posterior to eyes and vertex yellow. Fastigium yellow, narrow with a slight median furrow and four long apical setae; ocelli protruding, each one covered with dark markings. Scape light brown. Antennae light brown basally, then dark brown, with white rings widely spaced out. Face and mouthparts (except maxillary palpi) entirely dark brown, without a transverse yellow band; area between and below antennae yellow with dark brown patterns. Mouthparts dark brown, maxillary palpi white. Head lateral side brownish, area below eyes yellow. Pronotum yellow brown, mottled with dark patterns; lateral lobes light yellow, covered with white setae and with dark markings, with a whitish line separating lateral lobe from dorsal disk. Fore and median legs orange brown, covered with thin dark brown setae. Hind femora yellow mottled with dark brown, with a wide longitudinal band on external face; with a whitish ring before knees, black; hind tibiae dark brown except for a whitish area below knee. Tarsomeres 1–3 of each leg yellow basally, then dark brown. Tarsomere III-1 without spine on dorso-external edges. Abdomen whitish, mottled with dark brown and black patterns. Cerci light brown, short and conical. Subgenital plate brown, clog-shaped.

Male. Male genitalia ( Fig. 7 ): Pseudepiphallus conical, anterior margin flat and slightly indented (close to P. longipes ); lophi conical, membranous except their lateral edges, with dark brown apical setae. Rami thin and long, slightly converging apically. Pseudepiphallic parameres narrow and short, fused to pseudepiphallus dorsally. Ectophallic arc complete, wide and straight. Ectophallic fold narrow, with strong leaf-like lateral sclerites; apex narrow and sclerotized dorsally. Ectophallic apodemes very long and thin, slightly diverging. Endophallic sclerite sclerotized and large, its posterior apex with lateral arms diverging and with a short median expansion. Endophallic apodeme with both narrow lateral lamella and longer than wide dorsal crest. Membrane of endophallic cavity smooth.

Female. Unknown.

Habitat and life history traits. The holotype was collected during daytime, resting on top of a moist leaf at low elevation, in a little-disturbed tropical montane forest, which floor is composed of ferns, vines, saplings, seedlings, pandanus, palms and herbs ( Fig. 9 ).
