1945-97.”/ “Perileptus imaicus Jeannel, lectotype, Deuve & Kavanaugh des. 2016”. Type locality: India,
Uttar Pradesh, Kumoan, west Almora. Paralectotypes (a total of 8), labeled same as lectotype, in BMNH
and MNHN.
DIAGNOSIS.— Adults of this species (Fig. 5a) can be distinguished from those of all other
species in the region by the following combination of character states: size small (BL = 2.6 to 2.8
mm), fully-winged; body color reddish with apical part of elytra darker; microsculpture of elytra
effaced; dorsal pubescence sparse and long; pronotum slightly transverse (ratio Pw/PL = 1.32),
distinctly convex, with lateral margins markedly rounded in anterior half, straightened just anterior
to basal angles, the latter acute and sharp and laterally projected, median basal area coarsely
punctate; elytra shiny, moderately flattened, with striae coarsely punctate.
COMMENTS.— Perileptus denticollis Jeannel (1923), known from the Dali region of Yunnan
Province, is probably conspecific with P.imaicus because there appear to be no morphological features
to distinguish members of these two nominal species. Members of Perileptus davidsoni
Deuve (1989), described from the Kathmandu area in Nepal, also are externally similar in form and
structure to those of P. imaicus, but the apex of the median lobe of the aedeagus of males of
P.davidsoni is more broadly rounded (more narrowly rounded in P.imaicus males (Fig. 5b)).
HABITAT DISTRIBUTION.— Members of this species have been found in daytime on sandy flats,
in gravel and under stones along the open, unshaded banks of small to large streams running
through agricultural areas and other disturbed areas at elevations ranging from 680 to 2030 m (Fig.
35a). Most specimens were driven from their hiding places by splashing the banks with water from
the stream. At the collecting site in Longyang County (see below), members of this species were
found syntopic with members of Perileptus pusilloides sp. nov.
