This specific name pinkhami is derived from the name of the type locality, Pinkham Notch in the White Mountains of north-central New Hampshire, United States. The notch was formed by extensive erosion due to movement of the Laurentide Ice Sheet during the Wisconsinan Glaciation Event. Diagnosis. Distinguishable by the subparallel body, slightly transverse and angular pronotum, elytra at suture about as long as pronotum along midline, integument dark brown with slightly paler elytra (Fig. 7a); apical part of tubus of median lobe of aedeagus narrow, strongly produced ventrad and with small apical hook (Fig. 7b). Description. Body length 3.5–4.0 mm, moderately convex, slightly glossy, narrowly subparallel, head, pronotum, elytra and base of abdomen about the same width; integument dark brown with paler (dark reddish) elytra and legs (Fig. 7a); forebody moderately densely pubescent, pubescence of pronotum directed laterad from midline and on elytra latero-posteriad, punctation fine, microsculpture not apparent at low magnification; head round posteriad, eyes as long as posterior region of head, not expanded outside contour of head; antennomeres elongate, progressively less so toward apex of antennae; pronotum slightly transverse and angular; elytra with shallow postero-lateral emargination; abdomen slightly widening to mid-length, sides broadly arcuate. Male . Tergite VIII transverse, apical margin arcuate (Fig. 7c); sternite VIII strongly elongate, parabolic apically, antecostal suture distal to base of sternite (Fig. 7d); median lobe of aedeagus in lateral view with broadly elongate bulbus and lunar-shaped crista apicalis in ventro-posterior part of bulbus; tubus narrowly triangular, ...
