Phortica (Ashima) dianmianensis Gong, Zhu & Chen, 2018: 439 .

Diagnosis. Apical, leaf-like expansion of arista roundish apically; surstylus without expansion at caudoventral corner (ch.35-0); anterior postgonites with 5 and 3 acutely pointed, narrowly triangular, flap-like projections on left and right lateral lobes of aedeagal sheath, respectively (“Fig. 20” in Gong et al. 2018).

Supplementary description (not repeating characters common to P. foliisetoides ). Supracervical setae 12–14. Cibarial, medial sensilla approximately 7 per side; posterior sensilla approximately 5 per side. Setulae just before prescutellar acrostichal setae as short as other acrostichal setulae (ch.15-0).

Specimen examined. Thailand: 1♂, Chaiprakan , Chiang Mai, 18.x.2009, H. Bänziger leg. ( SEHU) ; 1♂, Ton- luong Temple, Chiang Dao , Chiang Mai, 6.xi.2008, H. Bänziger leg. ( SEHU) .

Distribution. China (Yunnan), Thailand *.

Remarks. This species resembles P. sagittaristula in having the setulae just before prescutellar acrostichal setae as short as other acrostichal setulae and both posterior postgonites apically roundish, but can be distinguished from it by the diagnostic characters.
