This species is diagnosed by the following morphological characters:
♂
frons somewhat flat and impressed, fringed with dense white pubescence, roughened with longitudinal granules and small median tubercules above the epistomal margin; epistomal margin substraight with a fringe of long pale setae; vertex distinctly convex with minute granules; antennal scape curved, funicle with seven segments and club with 8 or 9 distinct pseudo-sutures marked by rows of setae; pronotum wider, one and a half times as wide as long, widest at the base, converging anteriorly with weak convex lateral margins; anterior margin somewhat straight with some minute granules, median line distinct but not forming any ridge; dorsal surface minutely granulate punctuate, covered with dense scale-like setae, some scattered erect hairs on entire base of pronotum; posterior margin with distinct ridge forming somewhat V-shaped divergence, laterally; elytra somewhat globose slightly longer than broad and almost double the pronotum; basal margin of each elytron outcurved with 13 or 14 crenulations; lateral margins strongly outcurved, gradually narrowing posteriorly and terminating into a angularly rounded apex; striae distinctly depressed marked with shallow punctures and reaching almost up to the elytral apex except striae 5 and 6; interstriae much wider, flat except basal one-fifth becoming somewhat convex with distinct regular asperities; discal interstriae with three to four rows of granules and covered with scale like minute setae throughout; declivity commencing on the posterior third, gradually slopping posteriorly with convex face; declivital interstriae with somewhat distinct minute tubercules becoming somewhat prominent towards apex; body length:
3.46 mm
, 1.58× as long as wide.

Distribution:

Hosts:
Quercus floribunda

Q. semecarpifolia
(
Fagaceae
)
Phylogenetic assessment:
The Himalayan
Sphaerotrypes montanus
, along with other closely related species of the genus (
S. hagedorni
Eggers, 1920
) and other genera (
Hylesinus
, and
Dryocoetes
), were subjected to a phylogenetic study utilizing the COX-1 gene. Due to a lack of COX-1 sequences of
Sphaerotrypes
(except
S. hagedorni
) in GenBank, it was compared with species from other closely related genera. The phylogenetic tree, however, (
Fig. 17
), revealed that
Sphaerotrypes montanus
constituted a distinct group/clade from the others and had a nucleotide divergence of 19.43% from
S. hagedorni
.
The populations of the other genera were monophyletic individually in the current study.
