Jin, Xingbao, Liu, Xianwei & Wang, Hanqiang, 2020, New taxa of the tribe Meconematini from South-Pacific and Indo-Malayan Regions (Orthoptera, Tettigoniidae, Meconematinae), Zootaxa 4772 (1), pp. 1-53 : 13-14

20) Leptoteratura (Rhinoteratura) chaseni ( Karny, 1926, Xiphidiopsis ) comb. n.

1♂ (head and abdomen broken, attached on card): MALAYA (W)/ Selangor Ulu / Langat , 300–/ 390m, VI.14.1958; T. C. Maa / Collector

Note. This male specimen with fastigium of vertex and head distinctly flat, more or less truncate apex. Pronotum with flat disc. Hind tibia with pairs of apical spurs. Male cerci thickened lobe with a bifurcated basal projection and a sharp bristle inwardly ( Fig. 6a, b ), just like Xiphidiopsis chaseni Karny (1926: 131 , fig. 34, f.), the fastigium of vertex and head quite flat ( Cigliano et al., 2019), plus the locality of this specimen is same as one female of Karny’s species’— Selangor. It is here to transfer this species from Xiphidiopsis to Leptoteratura (Rhinoteratura) , though it was mistakenly suggested that it may belong to Xizicus (Axizicus) by Jiao et al. (2013).

Carefully compare with Leptoteratura (Rhinoteratura) borneoensis Jin, 1995 , which is no significant differenced from Leptoteratura (Rhinoteratura) chaseni ( Karny, 1926, Xiphidiopsis ) and here to be synonymized with it.
