Sejanus brevinger Yasunaga

Sejanus brevinger Yasunaga, 2001: 124 , figs. 6, 11 (n. sp., descr., disc., DV, MG).

DIAGNOSIS: Recognized by small size, completely dark brown hemelytron lacking any white pigmentation on anterior margin of cuneus, completely dark metafemur, and rounded apex of endosoma.

DESCRIPTION: See Yasunaga (2001).

HOSTS: Mallotus sp. (Euphorbiaceae) .

DISTRIBUTION: Japan (Shikoku, Kyushu, Ryukyus: Okinawa Is.).

DISCUSSION: The small size, short metafemur, dark hemelytron and body, and the Cshaped endosoma as illustrated and documented in the original description clearly indicate this species firmly belongs to Sejanus , even though we were unable to examine specimens of this species directly. The almost completely dark brown coloration of is species is unique, whereas most Sejanus species have at least part of the cuneal margin white and the apical half of the tibiae golden.

HOLOTYPE: JAPAN: Ryukyus: Okinawa Is., Mt. Nishimedake, Kunigami Village ., 25.v.1993, T. Yasunaga. 18 ( HUES) [not examined].
