Pityokteines sparsus
Wood & Bright, 1992
Pityokteines sparsus is a of bark beetle in the Curculionidae, described by Wood & Bright in 1992. The species is known from scattered records across northern North America including the Canadian provinces of Alberta, Manitoba, New Brunswick, and Labrador. As a member of the Pityokteines, it is associated with coniferous , though specific biological details for this species remain poorly documented. The limited number of observations suggests it may be uncommon or underrecorded.

Identification
Members of Pityokteines are small bark beetles (2-3 mm) with a compact, cylindrical body form typical of the tribe Ipini. The can be distinguished from related bark beetles by features of the declivity and elytral ornamentation, though -level identification requires examination of genitalic structures and detailed comparison with . P. sparsus specifically differs from other Pityokteines in subtle characters of punctation and body proportions as described in the original species .
Habitat
Associated with coniferous forests; specific microhabitat requirements unknown but inferred from to involve breeding in bark of fir (Abies) and spruce (Picea) .
Distribution
Recorded from Alberta, Manitoba, New Brunswick, and Labrador in Canada. The disjunct distribution pattern suggests either genuine rarity, undercollection, or possible misidentification issues in historical records.
