64 Masami HayashiMale genitalia (Figs. 124-127).Similar to those of takasagona at a glance; pygoferbarrel-shaped, ca 1.9 X as long as wide, not so narrowed even at the apical and basalparts, with the ventral margin expanded near the middle; a pair of pygoforal ventral lobesthin, widely apart from each other; uncus lobe gently curved, nearly straight anddorsovevtrally thickened in the apical part; innermost base of membranous lining underuncus lobe centrally sclerotized, forming a central inner support of the lobe; theca verythin, curved at the apical 1/4, with rather large basal plates, and with a pair of smallspines on underside of the apex; apical membranous part oftheca suffused to middle oftheupper surface; vesica very long, cylindrical, somewhat compressed near the base,protruding upwards and almost perpendicular to thecal apex, without saccate process atthe tip (cf. Hayashi 1978).Body length: f 42-46 mm, 4 36-42 mm. Total length: 59-68 mm.Expanse of forewings: 117-129 mm.Exuviae (Fig. 128). I formerly described the exuviae ofthis species on the basis ofthesame material (Hayashi 1978); here, some additional descriptions are given. Frontoclypeus roundly swollen, with 11 transverse rows of hairs;antenna 8-segmented, about 10:7.5: 7.5: 7.5: 8: 6: 3: 3 in the ratio of each segmental length, according to the presentmeasurement, and the 8th segment constricted at the apical 3/5; fore femoral anteriorcomb composed of 5-6 teeth; caudal margin of f 9th abdominal sternum bigibbous;anterior angle of 10th segment conically raised at the middle. Body length: 33.4-34.2mm, head width: 12.0-12.3 mm. Exuviae examined: 2ff, Tombol Bridge~Darapani~Fig. 128. Exuviae of C. intermedia. A, Frontoclypeus and clypeus in lateral view; B, rightantenna; C, left fore leg; D, apical partof abdominal venter(f). Scales, 1mm.
