Neoterpnosia
n. gen.
TYPE
SPECIES
. —
Terpnosia oberthuri
Distant, 1912
, by present designation.
ETYMOLOGY. — The generic name means “new
Terpnosia
”, having the prefix of
neo-
.
DIAGNOSIS. — This genus is distinguished from any other genera in
Euterpnosiina
by the following characters: fore wing basal portion of RA2 (or basal vein of apical cell 1) very short, about one third or less than one third as long as longitudinal portion of RA2 (or longitudinal vein of apical cell 1); fore wing basal portion of RA2 forming an angle of about 135 degrees to longitudinal portion of RA2; male abdominal tergites 2-5 or 2-6 with sublateral or lateral patches with a lighter color (which is almost same as the color of abdominal sternites); male abdominal segments 3, 4, and 5 each moderately inflated laterally; male abdominal sternites without tubercle-like projections. This genus appears to be closely related to
Calcagninus
Distant, 1892
considering the similarity in RA2 vein of the fore wing, but
Calcagninus
is distinguished by the following characters: head and thorax more slender; male abdominal sternites III and IV with tubercle-like projections; male abdominal segments 3, 4, and 5 not inflated laterally.
DESCRIPTION
Body small (
18.9-21.7 mm
long in males). Head about as wide as or narrower than base of mesonotum, depending on species. Lateral pronotal collar not dentate. Wings hyaline with marginal areas extremely narrow. Fore wing basal portion of RA2 about one third or less than one third as long as longitudinal portion of RA2.Fore wing basal portion of RA2 forming an angle of about 135 degrees to longitudinal portion of RA2. Male opercula very small, scale-like, not extending beyond posterior margin of sternite II; widely separated from each other.Timbal with five ribs. Male abdomen distinctly longer than head and thorax together. Posterior margin of male abdominal tergite 3 distinctly wider than anterior margin of mesonotum.Timbal cover minute, rudimentary, much wider than long. Fourth segment of male abdomen without molarlike projections laterally. Male abdominal sternites without tubercle-like projections. Male pygofer narrowly elliptical in ventral view, with posterolateral margins parallel-sided. Uncus not bifurcate, with incised apex. Basal lobe of pygofer well developed. Aedeagus thin. Ovipositor moderately protruding beyond abdominal segment 9.
SPECIES INCLUDED. — Besides the
type
species
Neoterpnosia oberthuri
(
Distant, 1912
)
n. comb.
and the two new species described below, this genus also includes
Terpnosia versicolor
Distant, 1912
. This species is morphologically very similar to
Neoterpnosia oberthuri
n. comb.
and is morphologically compatible with the above description of
Neoterpnosia
n. gen.
Here,
Terpnosia versicolor
is transferred from
Terpnosia
Distant, 1892
to
Neoterpnosia
n. gen.
to become
Neoterpnosia versicolor
(
Distant, 1912
)
n. comb.
Neoterpnosia
n. gen.
has been found from
China
(western part),
Vietnam
,
Myanmar
, northeastern
India
(
Arunachal Pradesh
),
Bhutan
, and
Nepal
.
