Michael Franzen & Walter Heinz: Morphology and Natural History of Mantica horni 299 Male genitalia. Shape of aedeagus moderately elongate and evenly curved, with considerably thick- ened basal part and very tiny apical knob (Fig. 2c); it lacks any structures like concavities, lateral flanges or lobes; dorsal ostium (apical orifice) very long, forming about 40% of aedeagal length, and basally divided by narrow, sclerotized thorn (Fig. 2c). Internal sac (Fig. 2a, b) strongly elongate, with large and protuding, thumb- like basal bladder; dorsally a long sclerite which is pro- bably identical with ligula sensu ISHIKAWA (1978). Truncal tube extremely elongate, formed by basi-lateral right bladder. Sclerites and bladders on apical portions only indistinctly discernible in our specimen. The iden- tifiable stuctures include a prominent praeputial pad, ve- ry long flagellum, relatively small medial tooth, upper limitator, and shield (Fig. 2a. b).. Fig. 2: Male genitalia of Mantica horni. a) internal sac, right lateral view; b) apex of internal sac, left lateral view; c) adeagus. Sclerites: fl = flagellum, li = ligula, mt = median tooth, sh = shield, ul = upper limitator; bladders: B = basal bladder, BLR = basi-lateral right bladder, PP = praeputial pad. Scale bars: 3 mm. The aedeagus and the general internal sac proportions and structures resemble those of Manticora livingstoni almost completely. The only exception is the lack of a praeputial pad in Manticora. However, it may be that this structure has been incompletely blown in the latter. Female external genitalia. In two females ovi- positors everted with a length of 32-34 mm (oviduct + ovipositor). Sternum eight (Fig. 3a, b) apically broadly rounded, with narrow, triangular medial emargination; apex with numerous short, fine setae. Second gonocoxa with no ventral groove or n
