Genus Ischnostrangalis Ganglbauer, 1889

Type species: Leptura (Ischnostrangalis) semenowi Ganglbauer, 1889 .

DIAGNOSIS. The genus is closely related to the genus Parastrangalis Ganglbauer, 1889 described initially also as a subgenus of Leptura in the same text

(Ganglbauer, 1889). However, the current definition of Ischnostrangalis is quite strict, especially when compared to a rather broadly defined genus Parastrangalis –

all species of Ischnostrangalis have relatively long body with pronotum strongly constricted well behind the apical margin and elytral apices with outer spines. For more details, see, for example, Ohbayashi & Lin (2013) or Tichý & Viktora (2017).

The genus consists of three groups. The species described below as a new belongs to I. semenowi group, which can be characterized by body covered by golden pubescence and brownish-yellow elytra with black markings laterally. The second group was reviewed by Ohbayashi & Lin (2013) and is characterized by black body and elytra with transverse yellowish fasciae ( I. manipurensis Gahan, 1906 and three related species). The last group currently consists of I. rhododendri Holzschuh, 2011

only, a species resembling the first group, except of not so constricted pronotum,

smaller size, narrower body and longer antennae and thus, approaching to some species of Parastrangalis .
