CITROGRAMMA SP. B

Citrogramma sp. B of Wyatt, 1991: 166. Type locality: Myanmar: Nam Tamai Valley. Wyatt,1991: 157 (ident. key), 166 (descr.).

Geographical distribution: Myanmar. Diagnosis: Species with yellow face, anepisternum and anepimeron yellow, yellow scutellum, abdomen with a yellow fascia reaching lateral margins, pro- and mesofemur yellow, and wing bare basally. Very similar to C. clarum , but it has wing with larger bare areas basally ( Fig. 134 ).

Remarks: Only one female is known with this wing microtrichia pattern ( Fig. 134 ). Wyatt (1991) included a male and a female, but only the female has wing with large bare areas basally. The male was misidentified, here named as C. amarilla . As Wyatt suggested, this female is treated as a distinct undescribed species, to be named and described when more material, especially males, are procured for study.

Material examined: MYANMAR: Nam Tamai Valley , 3000 ft, 27°42′N, 97°54′E, 26.vii.1938, R . Kaulback [1♀, BMNH] .
