49712475FFEBFF8752B3FA81FDA9F862.taxon	description	Female. Differs from male in having protibiae with elongate spur; clypeus without horn; pronotum narrower, feebly depressed on disc and without umbones and medial tubercle. Variability. Body length of examined specimens varies from 6.5 – 9.0 mm. Clypeal horn of males varies from very short (wider than long) to 3 times longer than wide. Medial tubercle on pronotum and especially umbones are less developed in some specimens.	en	Frolov, Andrey V.

49712475FFEBFF8752B3FA81FDA9F862.taxon	distribution	Distribution. The species was described from “ Nyassa-Land ” without more precise locality. The two exact localities known (Uzungwa Scarp Forest Reserve near Chita and Mafinga) are situated in Uzungwa — the southernmost and largest bloc of Eastern Arc Mountains (Burgess et al. 2007). The other locality, Upangwa, refers to the part of Livingstone Mountains south of Uzungwa. Available data suggest that O. planicollis inhabits mid-altitude afromontane forests and is apparently a litter dweller.	en	Frolov, Andrey V.

49712475FFEAFF8452B3F97BFEBAFF12.taxon	description	Description. Holotype, male. Body elongate, convex, shiny (Fig. 2), length 8.5 mm. Color uniformly dark brown, legs and elytra lighter brown. Head: Clypeus wide, with feebly convex anterior margin, rounded laterally, finely bordered. Genae small, not protruding past eyes. Eyes relatively large (width about equal to distance between eye and gula in ventral view). Frontal suture feebly distinct laterally, broadly interrupted in the middle. Clypeus with short, depressed tubercle slightly sinuate apically. Dorsal surface of clypeus and frons almost impunctate. Labrum deeply sinuate in the middle, relatively feebly protruding past clypeus. Pronotum: trapezoidal, with angulate sides, about 1.7 times wider than long, with impressed disc and 2 feebly marked longitudinal umbones aside of the disc, with a conical tubercle in the middle near base. Anterior angles acute; posterior angles obtuse, more or less distinct in dorsal view. Pronotum distinctly bordered on anterior margin and base. Base of pronotum punctate with a row of relatively small rounded punctures (Fig. 4, arrowed). Sides and disc with rounded punctures separated by about 2 – 3 puncture diameters. Lateral margins with long, sparse, brown setae. Scutellum: shape subtriangular, narrowly rounded apically, small (about 1 / 20 the length of elytra). Elytra: Surface convex, 1.1 times longer than wide, with humeral umbones. Elytra widest in the middle. Sutural striae feebly distinct, other striae indistinct. Elytra with sparse double punctation, larger punctures separated by 5 – 10 times their diameter. Wings: fully developed. Legs: Protibiae with shape typical to Orphnus species, with 3 outer teeth. Lateral margin basad of outer teeth not crenulate. Apical spur of protibia absent. Protarsi well developed, about 4 / 5 length of protibiae. Claws 1 / 3 length of apical tarsomere. Apical protarsomere slightly longer than tarsomere 3 and 4 combined. Mesolegs and metalegs are similar in shape; metafemora and metatibiae about 1 / 8 longer than the mesofemora and mesotibiae. Tibiae somewhat triangular with 2 apical spurs, inner margin almost straight, with 1 transverse keel. Upper spur of tibiae as long as two basal tarsomeres. Claws 1 / 3 length of apical tarsomere. Femora almost impunctate. Abdomen: Abdominal sternites irregularly punctate, pubescent, with sparse, long setae. Sternite 6 medially shorter than sternites 2 – 5 combined. Pygidium: Surface transverse, irregularly punctate with transverse punctures, pubescent with sparse setae. Aedeagus: with relatively long parameres, tapering apically (Fig. 10). Internal sac without spinules, with a large, curved sclerite (Figs. 7 – 8). Female. Unknown. Paratype. The single male paratype differs from the holotype in slightly larger size of the body (length 9.0 mm).	en	Frolov, Andrey V. (2013): New and little known species of the genus Orphnus MacLeay (Coleoptera: Scarabaeidae: Orphninae) from the East African Rift. Zootaxa 3710 (3): 297-300, DOI: 10.11646/zootaxa.3710.3.8
49712475FFEAFF8452B3F97BFEBAFF12.taxon	diagnosis	Diagnosis. Orphnus planicollis and O. demeyeri should be considered as a distinct species group characterized by the shape of the pronotum (with depressed disc and conical tubercle medially near basal margin), relatively long mandibles, and internal sac without spinules but with a large curved sclerite. O. demeyeri differs from O. planicollis in having sparse punctation of pronotum disc (Fig. 1), base of pronotum with relatively small rounded punctures (Fig. 4) as opposed to a row of elongate longitudinal punctures in O. planicollis (Fig. 3), shape of internal sac sclerite (Figs. 5 – 8), and aedeagus with more curved (in lateral view) and less twisted (in dorsal view) parameres (Figs. 9 – 10).	en	Frolov, Andrey V.

49712475FFEAFF8452B3F97BFEBAFF12.taxon	distribution	Distribution. The new species is so far known from one locality in the Upemba National Park. The area is a part of Mitumba Mountain range and adjacent to the Albertine Rift afromontane forest zone. Lusinga is situated on the plateau with overage altitudes exceeding 1700 m. Vegetation is mostly a grassland but east of Lusinga there are patches of ravine forest where the specimens of O. demeyeri probably originated.	en	Frolov, Andrey V.
