Hoplophthiracarus kumboensis sp. nov.

( Fig. 4A–H )

Measurements of holotype. Prodorsum: length 303, width 212, height 106; prodorsal setae: sensillus 111, interlamellar (in) 109, lamellar (le) 38, rostral (ro) 51; notogaster: length 535, width 394, height 364; notogastral setae: c 1, h 1 and ps 1 111; genitoaggenital plate 152×121, anoadanal plate 139×86.

Description. Colour light brown. Body surface covered with deep, regular, rounded foveoles.

Prodorsum with narrow fields, lateral longer than median; lateral carinae reach the sinus; posterior furrows absent; sensilli long, filiform, flexible, ciliated in distal half; interlamellar setae rather long, rigid, semi-erect, rather pointed distally, covered with small spines in distal end, similar in shape to notogastral setae, lamellar setae very short, spiniform, rostral setae longer, also spiniform, rough, exobothridial setae vestigial.

Notogaster with rigid setae, of medium size (c 1 /c 1 -d 1=0.9), rather pointed distally, covered with small spines in distal half, setae of row c remote from anterior notogastral border, setae c 2 and c 3 more than setae c 1; vestigial setae f 1 anterior of setae h 1; two pairs of lyrifissures, ia and im, present.

Ventral region. Setae h of mentum minute; formula of genital setae: 6 (4+2): 3; anoadanal plates with setae dagger shaped, only adanal setae ad 3 minute, spiniform, situated near paraxial border, anal setae shorter than adanal setae ad 1 and ad 2, adanal setae ad 2 remote from paraxial border.

Legs. Leg setation complete type, setae d of femora I bifurcated distally and situated at distal end of article.

Material examined. Holotype and three paratypes are deposited at DATE from the locus typicus: North–West Province, Mt. Oku, about 12 km W of Kumbo, 4–5. V. 2006, latitude 06°13'17.64" N, longitude 10°30'13.26" E, altitude 2800 m, montane foggy forest, litter and soil sifting sample, leg V. Grebennikov, two paratypes are deposited at ISB and one paratype is deposited at NHMG all from the same locality.

Etymology. The specific epithet kumboensis refers to the locality of this species.

Comparison. The new species is easy distinguishable from congeners by the shape and length of sensilli, long and narrow fields of prodorsum, minute setae h of subcapitular mentum, and bifurcated setae d of femora I.
