ANIC ( Rentz et al. 2006 , Su, per email) The specimens at hand are morphologically quite similar to that described in detail by Helfert & Sänger (2007) as Eumecopoda cyrtoscelis cyrtoscelis . However, they differ in song from the two populations studied there. Therefore we consider our specimens as belonging to a distinct island subspecies. The stridulatory files do not seem to differ. The closely related species E. superba Bolivar, 1898 occurs also in NW Papua. The type locality „Hassam“, given by Bolivar (1898) and not traceable in any gazetter, is obviously an error, since on the label of a (syn-?) type (see Paris 1994) in NMPC the word „Hattam” is given ( Machackova & Fikacek 2014 ). Hatam or Hattam is the name of a language/tribe in NW Papua living on the mainland of New Guinea (https://en.wikipedia.org/wiki/Hatam_language) near (to the island of) Mansinam where the species was listed by Griffini (1908) . The specimens of E. superba are clearly larger than ours and that from Helfert & Sänger (2007) (see Tab. 6 ). The distribution of E. cyrtoscelis , E. s uperba, E. spinosa Gorochov, 2020 and E. moluccarum ( Griffini, 1908 ) around Northwestern New Guinea is given in Fig. 21 . Diagnosis. In the calling song of the species, trills with durations from several seconds to more than a minute were observed, clearly different from the much shorter segments of a „broken trill“ (called „continuous (short) caller“ by Römer in Helfert & Sänger 2007 ) observed in Eumecopoda c. cyrtoscelis by Helfert & Sänger (2007 ; fig. 32). In morphology, possibly some body relations like tegmen to femur in the female differ between subspecies (or populations) but there are too few data for safe conclusions. Derivatio nominis. Named in honour of Prof. Dr. R. D. Zhantiev, Moscow State University, the pioneer of bioacoustics of insects (author of a book with same title in 1981 and of many papers before and after this date) in the USSR and Russia . FIGURE 19.

*mean Measurements: see Tab. 6 . Song. The calling song of the species consists of trills with durations from several seconds to more than a minute ( Fig. 10 ; Tab. 7 ). It should be noted that the stridulatory file of a male from Sideia Island (extreme SE New Guinea ), identified as E. cyrtoscelis ( Rentz et al. 2006 ) , differs distinctly from our specimen and from that of Helfert & Sänger (2007 ; see Fig. 12 ). Coloration. Dark brown.
