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.
