Philetus kitsi sp. nov. (Figs 1–5) urn:lsid:zoobank.org:act: 2E951D56-6D9E-4FF2-89B5-E3B88BC411EE Type material. HOLOTYPE, ♂ labelled: “ CANADA: YT: Richardson/ Mtns., 67°46ʹ43.22ʺN / 136°41ʹ55.86ʺW, 850m,/ 29.vii.2019, Malaise trap,/ shrub tundra, JK19-075,/ J.H. Kits, CNC1614247 ”; “HOLOTYPE/ Philetus kitsi / Cumming & Brooks [red label]” [dissected terminalia in microvial]. Type deposited in the Canadian National Collection of Insects, Ottawa, Canada (CNC). Diagnosis. Philetus kitsi sp. nov. is characterized by male terminalia with elongate simple cercus connected to lengthened ventral subepandrial lobe with digitiform apex (Fig. 3) and thumb-like preapical medially-directed process (Fig. 5), large epandrial lobe with posteriorly hooked dorsal process, and hypandrium with dorsally prolonged narrow median apical process (Figs 3, 4). In addition, the longer more narrowly produced apex of the antennal postpedicel (similar to P. memorandus) separates this species from most specimens of P. schizophorus. Description. Male. Body length 3.5 mm, dark brownish grey, covered with silvery grey tomentum (Fig. 1). Antenna dark brown to black; postpedicel pyriform with apex narrowly produced towards stylus. Legs brown to greyish brown. Wing hyaline with brownish veins. Halter brownish white. Terminalia: hypandrium with long hook-shaped apical rods arising above base of long, dorsally directed, narrow median apical process (Fig. 3); postgonite projected dorsally as wide rounded lobe; phallus tubular, apex partially desclerotized and slightly expanded in dorsal view (Fig. 4); anterodorsal margin of hypandrium partially fused with anteroventral margin of epandrium; epandrial lobe large with series of short setae on outer and inner margins and posteriorly hooked dorsal process; ventral subepandrial lobe lengthened, shiny, with digitiform apex (Fig. 3) and thumb-like preapical medially-directed process (Fig. 5); ventral subepandrial lobe connected basally to cercus; medial subepandrial lobe absent; cercus elongate, simple, ...
