14) Phortica (Ashima) pavriarista Cheng & Chen, 2008

Phortica (Phortica) pavriarista Cheng & Chen in Cheng et al., 2008: 620 .

Phortica speculum ( Maca & Lin, 1993) : Chen et al., 2005b: 420 (part, misidentification).

Phortica (Ashima) pavriarista: Chen & Máca, 2012: 507 .

Diagnosis. Arista only very slightly expanded apically (“Fig. 14” in Cheng et al. 2008); all postgonites strongly sclerotized, apically more or less pointed; posterior postgonite on only one lateral lobe of aedeagal sheath; lateral lobes submedially separated from each other; one lateral lobe of aedeagal sheath with 2 relatively close anterior postgonites (“Fig. 17” in Cheng et al. 2008).

Supplementary description (not repeating characters common to P. foliiseta ). Supracervical setae 12–14. Dorsomedial, tentorial apodeme 1/2 as long as basal, parallel portion of dorsolateral, tentorial apodeme. Longest, dorsal branch of arista shorter than longest seta on pedicel. Cibarial, medial sensilla 9–10 per side; posterior sensilla 4–6 per side. All tarsi with gray tarsomere V.

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. 17” in Cheng et al. 2008); but in B-type, vice versa.

Specimen examined. Thailand: 1♂ (B-type), above Sangwal, Doi Suthep , Chiang Mai, 1,250 m a.s.l., 6.i.2008, H. Bänziger leg. ( SEHU) .

Distribution. China (Yunnan), Thailand *.

Remarks. This species resembles P. andreagigoni in having the less expanded apex of arista, but can be distinguished from it by the diagnostic characters.
