Bioacoustics of Stictophaula multa

Remarks. Our single male specimen mostly resembles S. multa Gorochov & Voltshenkova, 2009 . Its male subgenital plate at its posterior end has lateral lobes that are elongated and slender and medial lobes that are very primitive, almost like nodules, not different from S. multa . But in our specimen, the medial lobes are situated at the middle of the posterior margin distinctly apart from lateral lobes ( Figs 12C, 12D ), unlike that illustrated in Gorochov & Voltshenkova (2009) . The median sclerite of the male genitalia is most similar to that of S. multa as suggested by the slender and elongated shape (in ventral view) and bent at nearly 90° (in lateral view) ( Figs 12E–G ). It is similar to Stictophaula aspersa Gorochov & Voltshenkova, 2009 from Mount Trus Madi and Stictophaula bruneii Tan & Wahab, 2017 from Brunei Darussalam , but slenderer and more elongated at apex (in ventral view). The stridulatory area, including the dark patterns on both tegmina, sinuous shape of the stridulatory file ( Fig. 12B ) and shape of mirror on the right tegmen, resembles S. multa more than S. aspersa and S. bruneii .
