Description.
Body length
3.6–3.9 mm
. Integument matt, blackish. Head long, length from cervical constriction to clypeus 1.4x as maximal width between genae, slightly rounded from cervical constriction to eyes, genae slightly surpassing eyes and with shallow impression, anterior margin of clypeus straight, symmetrical, frons without medial keel or impression, surface with dense confluent punctures, each puncture with a longer light decumbent, scale-like seta. Eyes not prominent, completely in conture of head. Antennae 11-segmented, shape of antennomeres as in
Fig. 6
, antennomere 2 1.0x as wide as long, antennomere 3 1.0x as wide as long. Pronotum long, narrow, 1.4x as long as wide, widest at anterior corners, sides straight convergent to base, posterior corners rectangular, anterior corners slightly protruding, disc without impression, without keel, rough punctures and scale-like setation as on head; prothoracic hypomera with similar punctures as on disc, without setation. Elytra elongate-oval, widest in middle, 2.4x as long as wide, humeral corners distinctly protruding forward, punctures in elytral rows large, dense as on pronotum, intervals flat but becoming convex laterally and apically, not keel-like, scale-like decumbent setation similar as on head and pronotum, lateral margin of elytra visible from dorsal near humeral angles and apically; scutellar strioles indistinct, short, impressed, each consisting of 2 punctures; epipleura with a row of large punctures along entire length. Ventrites with distinctly finer, sparser punctures than on pronotum, punctures with very short decumbent setation. Legs also with scale-like setation as on dorsal surface, without further peculiarities. Aedeagus as in
Fig. 12
, apicale somewhat bent to lateral side and so slightly asymmetric.
Diagnosis.
Stenosis mandalayca
sp. nov.
can be recognised by the unusual small size of body – below
4 mm
in combination by head with slightly rounded sides from cervical constiction to eyes, by long pronotum widest at anterior corners, by pronotum with slightly protruding anterior corners, by dense confluent punctures on head and pronotum, by lacking a medial impression on pronotum, by longer dorsal scale-like setation, and by the shape of the aedeagus. In the key of Oriental species of
Stenosis
by
Kaszab (1981)
, only
S. madrasensis
Kaszab, 1979
from south-eastern
India
is of similar small body size, but most other characters differ according to the given characters in the key. The aedeagi of nearly all Oriental
Stenosis
species
are unknown.
Etymology.
Named after the city
Mandalay
, in whose vicinity the
type
series was collected.
