Phortica ( Ashima ) saltiaristula : Chen & Máca, 2012: 507 . Diagnosis. Arista with 1 or 2 minute, dorsal branches basally (ch.5-1) and apical, leaf-like expansion roundish and irregularly serrated on apical margin; setulae just before prescutellar acrostichal setae somewhat longer than other acrostichal setulae (ch.15-1); pregonite slightly concave on dorsosubapical margin of apical knob (ch.48-1), strongly curved ventrad distally (“ Fig. 3D ” in Chen et al . 2005a ); anterior, sclerotized postgonite on right lateral lobe of aedeagal sheath not bifurcated (“ Fig. 3C ” in Chen et al . 2005a ); posterior postgonites both strongly sclerotized and apically pointed (“ Fig. 3C ” in Chen et al . 2005a ). Supplementary description (not repeating characters common to P . foliisetoides ). Supracervical setae 8–9. Dorsomedial, tentorial apodeme 1/2 as long as basal, parallel portion of dorsolateral, tentorial apodeme. Cibarial, medial sensilla 7–8 per side; posterior sensilla approximately 5 per side. Anterior postgonite on left lateral lobe of aedeagal sheath broadest, located subapically. Specimens examined.

This species is closely related to P . foliisetoides and P . sagittaristula ( Cao et al . 2011 ; An et al . 2015 ), but can be distinguished from them by the diagnostic characters.
