Sphagniana monticola (Kim
and Kim 2001)
몸길이는 약 16-17.7 ㎜로 작은 편이며 흑갈색이다. 겹눈 아래에서 뺨, 입틀 주변으로 이어지는 특징적인 흑색 띠무늬가 있다. 앞날개는 갈색이며 복부 끝에 도달하지 않으나 넓적하게 배를 덮는다. 한국의 고산지대 풀밭에서 드물게 발견된다.

Male: Body
small sized for the genus. Head relatively short with eyes large
prominent. Fastigium of vertex round smoothly, as broad as two times
of antennal scape dorsally. Notch closed between fastigia of vertex
and frons. Antenna as long as about 1.5 times of body length. Pronotum
with disc narrowed anteriorly. Median carina distinct in metazona,
lateral carina mostly indicated. V-shaped sulcus very clear, separated.
Lateral lobe of pronotum round at anterior angle. Posterior margin
oblique, slightly sinuate. Mesopterous. tegmina almost covering
abdomen very broadly, but not surpassing beyond abdominal end. Tegminal
apex truncate widely with very weak concave or not. Left stridulatory
files of CuP vein with about 75 teeth. Right speculum of tegmen
large subquadrate. Prosternum unarmed. Fore coxal process small
but clear. Fore tibia with 3 dorso-external spines and 6 pairs of
ventral spines. Middle tibia with 2 external, 4 internal spines
in dorsum and 6 pairs of ventral spines. Hind tibia with 25 external,
22 internal spines in dorsum and 8-9 pairs of ventral spines and
4 apical spurs distally. All femora without any spines or spinules.
Plantular of hind tarsus well developed, as long as 0.5 times of
basitarsus. Last abdominal tergite forming a pair of small triangular
lobes with a small V-shaped incision in median. Cercus very short
and thick, flattened dorso-ventrally, not projecting beyond subgenital
plate. Base almost covered by last abdominal plate. Internal tooth
of cercus located at base, very short and slender relatively to
apical part. Apex hook-like incurved. Subgenital plate extending
beyond cerci, caudal margin with V-shaped median incision. Median
and lateral carinae well developed. Style simple, as long as 4 times
of basal width. Titillators large developed comparatively to body
size, almost straight apical portion with median elevation dorsally.
Each sides of apical portion with denticles, apex sharply pointed.
Basal portion shorter than apical one.
Coloration:
General coloration dark brown. Antenna blackish brown. Around eyes
and gena with specific patterns of black band linked. Around of
mouthparts black. Lateral lobe of pronotum with marginal pale part
posteriorly or not. Tegmina brown with black veins.
Female:
Similar to male but slightly larger than male in profile. Tegmina
a little shorter than male, reside abdominal mid. Ovipositor black
moderately curved upward, basal part bright. Subgenital plate covering
base of ovipositor, forming a pair of lobes with apices sharply
tapering.
Measurements (unit: ㎜): Length of body
male 16.5, female 20.0; pronotum male 4.5, female 5.1; tegmen male
