Dionymus carmichaeli Chopard, 1928: 30 .

Xenogryllus carmichaeli — Chopard 1968: 350; Yin & Liu 1995; Cigliano et al. 2018 ( Orthoptera Species File Online). Madasumma carmichaeli — Chopard 1969: 311.

Nomen dubium— this study.

Taxonomic discussion. According to the description of Chopard (1928), the female of X. carmichaeli is similar to X. marmoratus in terms of shape, size and coloration. However, the male specimen described by Chopard possesses five oblique veins, which is not consistent with any other existing species of Xenogryllus, as noted by Chopard himself. It is probable that the type series was heterogeneous, the male belonging to another subfamily than Eneopterinae . The male type may belong to the genus Madasumma, according the subsequent identification of the species by Chopard (1969), while the female could belong to X. marmoratus . The type locality, “ India, Darjeeling District, alt. 100–300 ft, West Bengal ”, could fit with X. marmoratus, but also with X. transversus or X. maichauensis . Given these problems and the fact that the type series is missing in ZSI, Kolkata (RJ, pers. obs.), we consider this species as nomen dubium.
