Description. General habitus of the genus. Specimens collected in Java of brown color. Male cerci not very stout at base, narrow apical area moderately curved with internal apical tooth larger and stouter than pre-apical tooth. Subgenital plate with moderately long styli (longer than in “P. Ratu green“ = M. himalaya ). Morphologically the new species differs from M. himalaya -group that occurs in Palabuan Ratu (South coast of Java ) in the same locality by structure of the mirror and song, by the apical teeth of the male cerci arising from the end of the internal margin of the cercus. These teeth are moderately spaced and the apical tooth is stouter and larger than the pre-apical tooth, while in M. himalaya -group from Java arises nearly fully from the apical margin, the apical tooth is slightly less stout (than in M. himalaya ), both teeth are closer together, and by the styli of the male subgenital plate that are although short longer than in M. himalaya -group ( Fig. 2 ) and by the brown instead of mostly green color. Song. The calling song consisted of long (from a few seconds to more than one and a half minute documented) sequences of echemes ( Fig. 8 , 9 ; parameters Tab. 4 ) Measurements. 4 males , Java: Body w/wings: male 66–70 (67.3±1.9); body w/o wings: male 36–38 (37.3±1); pronotum: male 8.9–9.0 (9.0±0.1); tegmen: male 55–58 (56.6±1.6); hind femur: male 42–46 (43.4±1.9); anterior femur: male 10; tegmen width: male 13.0–15.2 (13.9±.9) mm. Male CH 7725, Sri Lanka : pronotum 8.5; tegmen length ca. 50 (slightly damaged); tegmen width 12; hind femur 39 mm . Literature data on song: Korsunoskaya 2008 ( CAMBODIA ) Specimens with this song type have been found in two widely separated areas, in South East Asia (in several Indonesian islands and in Cambodia and Thailand ; see below) as well as in Sri Lanka without obvious differences in morphology. Chromosomes ( CH 7725): 2n = 23, FN = 46; pairs 1 and 4–11 metacentric, 2 and 3 subacrocentric, X chromosome metacentric ( Fig. 15 ) Based on chromosome number (see Discussion), a female from Thailand ( Luanpirom et al. 1999 ) may also belong to this species. Uvarov (1927) mentions Mecopoda elongata from Sri Lanka (Museum Colombo); these specimens may either belong to M. javana or to M. mahindai sp. nov. (see below).
diagnosis · Plazi
Diagnosis. The calling song of the species has a distinctly lower number of syllables per echeme than the other species of the group except mahindai (see below) and a higher echeme repetition rate than most other species of the group ( Tab. 2 ). M. javana (specimen from Sri Lanka ) has also a chromosome number (2n = 23) lower than known from any other species of the genus.
