Holotype : ♂ , BMNH, by original designation. Type locality: Malaysia : Gunong Tahan. Curran, 1928: 199 , 206, 1931a: 313. Citrogramma pendleburyi of Knutson et al ., 1975: 311 ; Wyatt, 1991: 155 , 157. Geographical distribution: Malay Peninsula ( Pahang ). Differential diagnosis: Species very similar to C. marissa , with black facial vitta and costal cell bare. Citrogramma pendleburyi differs in having wing much more microtrichose basally (only cell CuP bare on anterior margin) ( Fig. 131 ; see Fig. 132 ) and a slightly broader eye angle (about 110°). Citrogramma marissa is only known from southern India and it is smaller than C. pendleburyi . Other morphological differences are the shape of yellow maculae on tergum 2 and the size of dark scutellar macula, much broader and more rounded in C. marissa (see Figs 119, 121 ). Remarks: Species only known from the holotype male ( Fig. 121 ). Holotype male deposited in The Natural History Museum, formerly British Museum (Natural History) (London, UK ) and labelled: ‘MALAY PENIN:/Pahang, F.M.S./ Gunong Tahan / Seat Point 5460′ / Dec: 21 st 192 2 / H.M.
