Strongylophthalmyia palpalis Papp in Papp et al. 2006: 168 . Iwasa & Evenhuis 2014: 103.

Diagnosis. This species is similar to S. sumatrana , n. sp. based on the yellowish to reddish brown thorax and modified male palpus, but S. palpalis can be differentiated by the spheroid male palpus ( Fig. 2 ) in (the palpus is flared apically and rounded but not spherical in S. sumatrana ), and the fore femur ( Fig. 72 ) dorsally has 2 long thorn-like spicules subbasally and 10–12 slightly shorter black spicules medially (2 long spicules basally and 5 short spicules apically in S. sumatrana ). The description in Papp et al. (2006: 168) gives excellent characters to identify this species. Photos of the antenna ( Fig. 32 ) and wing ( Fig. 50 ) are added here to further aid in its identification.

Remarks: Specimens of this species were unavailable for study. For a full description of this species, see Papp in Papp et al. (2006: 168).

Distribution: Thailand.
