15) Phortica (Ashima) nudiarista Cheng & Chen, 2008

Phortica (Phortica) nudiarista Cheng & Chen in Cheng et al., 2008: 619 .

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.

Specimens examined. China: 1♂ (B-type), Zhengxing, Jingdong , Yunnan, 24.vii.2009 ( SEHU) . Thailand: 1♂ (B-type), above Sangwal, Doi Suthep , Chiang Mai, 1,250 m a.s.l., 24.vii.2008, H. Bänziger leg. ( SEHU) ; 1♂ (Atype), above Sangwal, Doi Suthep , Chiang Mai, 1,250 m a.s.l., 9.i.2008, H. Bänziger leg. ( SEHU) ; 1♂ (B-type), path to Pha Lad, Doi Suthep , Chiang Mai, 5.x.2008, H. Bänziger leg. ( SEHU) ; 1♂ (B-type), path to Bung La U O, Ban Thi Pho Ji, Umphang Distr. , Tak, ~ 800 m, 22.i.2008, H. Bänziger leg. ( SEHU) . Malaysia: 1♂ (B-type), Ulu Gombak , Selangor, 9.xii.2013, M.J. Toda leg. ( SEHU) . India: 1♂ (B-type), Uttarakhand, Chamoli Distr., Simli ( Narainbagar ), 5.ix.2010, P.C. Sati leg. ( SEHU) .

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.
