The flower fly genus Citrogramma Vockeroth (Diptera: Syrphidae): illustrated revision with descriptions of new species Author Mengual, Ximo text Zoological Journal of the Linnean Society 2012 2012-01-17 164 1 99 172 http://dx.doi.org/10.1111/j.1096-3642.2011.00750.x journal article 10.1111/j.1096-3642.2011.00750.x 0024-4082 5406153 CITROGRAMMA CITRINOIDES WYATT, 1991 Citrogramma citrinoides Wyatt, 1991: 158 . Holotype : ♂ , BMNH, by original designation. Type locality: Malaysia : Mt Jasar. Wyatt, 1991: 158 , figs 6 and 14. Syrphus variscutatus of Curran, 1928 (in part). Geographical distribution: Malay Peninsula ( Pahang ), Hainan . Differential diagnosis: Distinct species only known from male specimens. Face yellow, lunule yellow, scutellum yellow, metafemur black and pro- and mesofemur yellow. Very similar to C. flavigenum but C. flavigenum with lunule black, brown macula on facial tubercle, and pro- and mesofemur black basally; both species yellow pilose on notopleuron and on supra-alar area, but C. citrinoides has little black hairs. Citrogramma flavigenum is only known from southern India . Remarks: Little variation was found in the type series and nontype material. The most evident is tergum 3 usually with a yellow fascia with parallel margins, but some specimens have this fascia slightly emarginate posteromedially ( Fig. 90 ). After the study of the type material, I realised that some individuals have pro- and mesofemur with a posterobasal brownish area, but entirely yellow anterobasally. This only posterior diffuse macula is very distinct from the other character state used in couplet 40 of the key: pro- and mesofemur black basally. A male was found labelled as paratype and not noted in the original description ( Malaysia , Pahang , Cameron Highlands , 5000–5500 ft , 12.vi.1935 , H.M. Pendlebury , BMNH ). The paratype male collected on 22.ix.1938 has a head glued on of a different syrphid genus, Allograpta Osten Sacken, 1875 . As mentioned by Wyatt (1991) , there are some individuals that were identified as paratype or paralectotype of C. variscutatum ( Curran, 1928 ) . They are placed in the nontype material.
