Phortica brachychaeta Chen & Toda in Chen et al ., 2005b: 422 (part, misidentification). Phortica ( Ashima ) nudiarista : Chen & Máca, 2012: 507 . Diagnosis. Arista apically with distinct, leaf-like expansion narrower than long and apically tapering and pointed but neither dorsal nor ventral branches (“ Fig. 8 ” in Cheng et al . 2008 ); one lateral lobe of aedeagal sheath with 2 anterior postgonites widely separated; the other lateral lobe with 1 posterior and 1 anterior postgonites (“Fig. 11” in Cheng et al . 2008 ). Supplementary description (not repeating characters common to P . pavriarista ). Supracervical setae 9–11. Cibarial, medial sensilla approximately 9 per side; posterior sensilla approximately 5 per side. The antisymmetry is observed in the postgonites: in A-type, the left lateral lobe bears 2 anterior postgonites, and the right lobe 1 posterior and 1 anterior postgonites (“Fig. 11” in Cheng et al . 2008 ); but in B-type, vice versa .

Distribution. China ( Yunnan ), Thailand *, Peninsular Malaysia *, India ( Uttarakhand )*. Remarks. This species resembles P . pavriarista in the morphology of the aedeagal sheath and postgonites, but can be distinguished from it by the diagnostic characters.
