(Text-figs 100-109; PI- 9< figs 210-221; Map 10) Pradatta bimaculata Moore, 1888 : 411. M. bimaculata is a variable species, in size, extent of pattern differentiation and colour. A combination of two characters, (1) the presence of a brown discocellular spot, occasionally faint but rarely indistinguishable against the surrounding colour, and (2) the modified form of the papilla analis devoid of terminal spines, separates M. bimaculata from other species in Masalia
. Bulletin of the British Museum (Natural History) Entomology. REVISION OF GENUS MASALIA 85 Masalia bimaculata (Moore) comb. n. (Text-figs 100-109; PI- 9< figs 210-221; Map 10) Pradatta bimaculata Moore, 1888 : 411. M. bimaculata is a variable species, in size, extent of pattern differentiation and colour. A combination of two characters, (1) the presence of a brown discocellular spot, occasionally faint but rarely indistinguishable against the surrounding colour, and (2) the modified form of the papilla analis devoid of terminal spines, separates M. bimaculata from other species in Masalia. Four subspecies are recognized, the structural differences being as follows: Areole present absent present or absent absent Though variation in colour and marking occurs between the four, pattern differ- ences are not marked and are further obscured by variation within, and slight overlap between, them. M. b. nigrifasciata, linking with M. b. bimaculata and M. b. cornia on presence and absence, respectively, of an areole is, on colour and mark- ing, the most readily distinguished. These differences are set out below. M. b. nigrifasciata. Costal and anal regions typically dull red, central region yellow- ish white to light yellow; dark brown lower central longitudinal streak well developed. M. b. bimaculata M. b. cornia M. b. nigrifasciata M. b. pluritelifora Cornutus Distribution present Indian present African present African absent African. Fig. 99.
