Description. Black, scape dark­brown or black, elytra bronze, pubescence silvery grey. Body length: 10.3–10.5 mm.

Head with sparse, short pubescence and with some long, erect hairs. Frons coarsely punctate between eyes; furrow between antennal tubercles visible. Cheeks slightly extended, covered with fine pubescence. Antennae longer than apex of elytra, bicolor: antennomeres 1–6 dark, with fine, silvery grey pubescence, ventral surface sparsely setose, antennomere 7–8 yellow, antennomeres 9–11 darkened. Labrum transverse, narrow, frontal margin with row of yellow brown setae.

Pronotum slightly elongate, subcylindric, with fine basal and apical marginal lines; sides slightly constricted after second third and behind apical margin: opaque, densely and coarsely punctate, with silver­grey pubescence. Pronotal disc without a longitudinal middle line.

Scutellum small, semicircular, with pubescence like that on pronotum. Smooth portion of pars stridens with very fine transverse microsculpture.

Elytra subparallel, narrowed in apical quarter, truncate apically, with acute small sutural and largeapical denticles; finely and irregularly punctate along suture and in apical quarter, with coarse punctation in basal portion, less coarsely, irregularly in preapical portion; each puncture with fine silver­grey seta, with semierect hairs in apical quarter. Elytra with five bands of silvery tomentum. Basal band transverse band behind shoulders; middle part of elytra with triangularly transverse band; apex with transverse band. Dorsal surface between transverse bands rather smooth, shiny, with very fine, relatively sparse pubescence.

Ventral surface of body with dense pubescence, with sparse, short, erect pilosity. Legs dark­brown, with very fine, silvery white pubescence and some erect hairs. Basal part of hind femura yellow. Tarsomeres dark.

Differential diagnosis. For determination of this species, see the key below.

Etymology. This species is named after my friend and colleague, staphylinidologist Dr. Alexey Shavrin (Daugavpils University, Latvia) in appreciation of friendship, excellent cooperation, and in gratitude for his contribution to the studies of Staphylinidae of the Philippines.
