Liara (Unalianus) brevipennis (Redtenbacher, 1891) , stat. resurr.

MATERIAL. Indonesia: Western Java, 20–25 km SE of Bogor City, Pangrango Mt,

environs of Cemande Vill., ~ 1000 m, 27.XI–7.XII 1999, 2 ♂, 6 ♀, A. Gorochov ( ZIN) .

NOTE. This species was originally described as a species from the Western Java. Later,

it was included in “ Oxystethus intermedius ” as its subspecies (Ingrisch, 1998). The specimens here examined are in accordance to the subspecies redescription by this author, i.e. they are somewhat larger than in L. (U.) intermedia . However, my specimens of L. (U.) brevipennis are additionally distinguished from those of L. (U.) intermedia by the tegmina slightly longer and having wider anterolateral corner of male mirror as well as narrower part of male dorsal field behind stridulatory areas (in L. brevipennis , this mirror is 1.3–1.4 times as wide as the latter field part; but in L. intermedia , this ratio is about 1.1), and by small differences in the male genitalia: distal portions of the genital sclerites are longer than proximal ones (in L.

intermedia, they are not longer than proximal portions) and more curved than in L. intermedia ;

small denticles on anterolateral surfaces of these distal portions are more distinct than in the latter species. Thus, these two taxa are closely related but different, and L. brevipennis is restored here in its original species rank.
