암컷
(Female)
Original description: Tetrix minor Ichikawa 1993
Small in size. Head smaller and fastigium
of vertex narrower than those of another Japanese species. Pronotum
in frontal view narrow, hardly tectate, usually extending to the
tip of ovipositor, and median and lateral carinae well marked (especially
in macropterous form). Anterior margin of pronotum truncate, not
produced forwards, and never curved upwards. Middle femora slightly
wider than the visible part of tegmina, the other characters of
legs as in T. japonica.
Wings usually hemimacropterous to macropterous and surpassing the
hindmost point of pronotum. Ovipositor very narrow.

Type series: Holotype ♀, Yodo River
(riverbed), Kanmaki, Takatsuki, Osaka Pref., 14. VI. 1984, A. Ichikawa
leg. Paratypes: 1♀2♂, same data as for the holotype; 6♂, Yodo
River, Oyodo-ku, Osaka Pref., 27. IX. 1986, A. Ichikawa leg.; 1♀2♂,
Yodo River, Fukushima-ku, Osaka Pref., 27. IX. 1986, A. Ichikawa

Biology. The species lives in low wet place,
and prefers reclaimed lands. The species is probably multivoltine
and hibernates at middle stage of nymph or occasionally at adult
stage.
Distribution. Japan (Honshu).
Remarks.
The species is closely allied to T. macilenta
n. sp., but can be separated from the latter in the smaller body
and usually macropterous form.
