039DE71C8D5DFFA15EAAFD28FBEDFD0E.taxon	discussion	Taxonomic Placement. Flaviellus consentaneus is a rarely collected species that is widespread in northcentral USA and the adjacent Canadian prairie provinces. It has characteristics that make taxonomic placement difficult. Gordon and Skelley (2007) remarked on this difficulty, compared it with Flaviellus subtruncatus (LeConte, 1878), and tentatively placed it in Melinopterus because it lacked some characteristics of more typical Flaviellus species. With questions regarding generic placement of the new species, we re-evaluated generic characters and placement of F. consentaneus. Table 1 provides the key characters used to classify F. consentaneus and the new species.	en	Smith, Andrew B. T., Skelley, Paul E.

039DE71C8D5DFFA15EAAFD28FBEDFD0E.taxon	distribution	Distribution. Gordon and Skelley (2007) cited this species from various localities in southern areas of the Canadian provinces of Alberta, Saskatchewan, and Manitoba and from North Dakota, South Dakota, and Minnesota in the USA. They also cited “ Northwest Territories: Abernethy ” as a locality but Abernethy is in southern Saskatchewan — this record may have been based on specimens collected prior to 1905, when Saskatchewan was still considered to be part of the Northwest Territories. The records of this species from the states of Kansas, Missouri, and New Mexico in the USA are dubious and should be disregarded (see commentary in Gordon and Skelley 2007). The type locality for this species is the shores of Lake Superior, and the lectotype was either collected by J. L. LeConte during his 1848 expedition or acquired by LeConte from other collectors (LeConte (1850) stated that specimens from multiple sources originating from around Lake Superior were used for his descriptions).	en	Smith, Andrew B.

039DE71C8D5DFFA65CB0FD63FD1DFB44.taxon	discussion	Taxonomic Placement. In addition to the characters in Table 1, this species is placed in the genus Flaviellus based on the following combination of character states. Head evenly convex, without tubercles; clypeus glabrous, weakly emarginate medially (Fig. 4). Pronotum widest from middle to base, evenly convex, with weak lateral fringe of setae in dorsal view, dark brown with lighter markings in apical corners (Figs. 1 – 2). Scutellum triangular, approximately one-eighth the length of elytra (Fig. 1). Elytral surface smooth, evenly convex, glabrous, light brown with darker markings basally (Figs. 1 – 2). Dorsal surface of protibia smooth, impunctate (Fig. 5). Male protibial spur modified (thick and bent downward 90 °) (Fig. 5). Male inferior mesotibial spur unmodified. Meso- and metatibial apices fringed with long and short spinules. Metatarsomere 1 shorter than superior tibial spur, longer than metatarsomeres 2 – 3 combined. Gordon and Skelley (2007) stated that the male metasternum (= metaventrite) is not deeply excavated and is without a patch of dense setae in Flaviellus. However, we observed that many (but not all) male specimens in all species in this genus have weak lateral rows of setae bordering a medially concave metaventrite. This character can be used as an aid in identifying the sex of all species in the genus.	en	Smith, Andrew B. T., Skelley, Paul E.

039DE71C8D5DFFA65CB0FD63FD1DFB44.taxon	diagnosis	Diagnosis. Flaviellus kluanensis is distinguished from the other species in the genus by the following combination of character states. Head and pronotum dark brown with light markings in the apical corners of the pronotum. Lateral pronotal margins evenly convex with the rest of the surface (not explanate). Lateral elytral margin fringed with setae shorter than scutellum near base. Protibia with basal half of outer edge serrate. This new species will key out imperfectly to Flaviellus subtruncatus (LeConte) in couplet 1 of Gordon and Skelley’ s (2007) key to Flaviellus species, based on the dark brown head and pronotum. Flaviellus kluanensis is distinguished from F. subtruncatus by the paler apical corners of the pronotum (entire lateral edge paler in F. subtruncatus), the sparse setation on the inner margin of the meso- and metatibiae (brush of long setae in F. subtruncatus), the male protibial spur bent downward in apical half (bent near apex in F. subtruncatus), and the apex of the male parameres thin and bend downwards 90 ° around a membranous (unsclerotized) fold (Figs. 6 – 7) (apex very slightly curved downward and entirely sclerotized in F. subtruncatus; see Gordon and Skelley 2007: fig. 656).	en	Smith, Andrew B.

039DE71C8D5DFFA65CB0FD63FD1DFB44.taxon	description	Holotype Description. Length 4.5 mm, width 2.0 mm. Color dark brown; head and pronotum with light brown markings in apical corners of pronotum (Figs. 1 – 2); elytra light brown with slightly different shaded markings, elytral base dark brown. Dorsal surfaces shiny, smooth, completely glabrous, evenly convex without any indication of tubercles or depressions. Head: Densely punctate near apex (separated by less than 1 puncture diameter), moderately punctate on disc (separated by 1 – 4 puncture diameters), and sparsely punctate along base. Frontoclypeal suture almost imperceptible (Fig. 4). Pronotum: With a sparse mixture of smaller and larger punctures, larger punctures increasing in density laterally. Pronotal lateral margins fringed with short setae in apical half. Elytra: Each with 9 distinct, punctate striae; interstrial surfaces impunctate to sparsely punctate with weak microsculpture. Lateral margin of elytron fringed with short setae near base. Elytral disc and declivity lacking setae. Legs: Protibia with 3 large teeth along outer edge, basal half of outer edge serrate; inner edge curved outward before insertion of apical spur (Fig. 4). Protibial spur thick and bent downward 90 ° on apical half (Fig. 5), lacking inner apical tooth. Meso- and metatibiae with short, sparse setae along inner margin. Mesotarsomere 1 and metatarsomere 1 longer than associated superior spur and longer than associated tarsomeres 2 – 3 combined. Venter: Prosternal peg (directly behind procoxae) erect perpendicularly with tuft of long setae. Metaventrite smooth, sparsely punctate, concave medially (Fig. 3). Abdominal sternites and pygidium evenly setose. Genitalia: Paramere apex thin, bend downwards 90 ° around a membranous (unsclerotized) fold (Figs. 6 – 7). Variation. Paratypes range 4.0 – 5.0 mm in length. Dorsal coloration is sometimes darker with almost black head and pronotum and dark brown elytra. Some males have a row of setae on either side of the medial metaventral concavity. It is difficult to characterize the lateral fringe of setae on the pronotum and elytra and the finer detail of the legs because all specimens examined were abraded to some degree. No female specimens were observed.	en	Smith, Andrew B. T., Skelley, Paul E. (2020): A New Species of Flaviellus Gordon and Skelley, 2007 (Coleoptera: Scarabaeidae: Aphodiinae) from the Yukon, Canada.

039DE71C8D5DFFA65CB0FD63FD1DFB44.taxon	biology_ecology	Natural History. Gordon and Skelley (2007) report that most species of Flaviellus are primarily psammophilous detritivores. However, recent collections of F. subtruncatus in New Mexico (P. Lago, personal communication) were in a wide variety of animal dung in high elevation meadows.	en	Smith, Andrew B.
