( Fig. 6H )

Phortica longipenis Chen & Gao in Chen et al., 2005a: 3957 .

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

Diagnosis. Apical, leaf-like expansion of arista much narrower than long, apically with 1 long, medial and 2 minute, lateral, awn-like projections (“ Fig. 4A ” in Chen et al. 2005a); strongly sclerotized arch on anterior margin of aedeagal sheath recurved at anterior ends as postgonites, posteriorly with one large and one small postgonites (projections); one anterior postgonite curved inward, longer, strongly sclerotized, apically with small claw, but the other curved dorsad, shorter, less sclerotized, without claw ( Fig. 6H ).

Supplementary description (not repeating characters common to P. semiannulata ). Supracervical setae approximately 16. Arista with arb = 1–3/0. Cibarial, posterior sensilla 6–7 per side. Pregonite without sensilla on submedial portion (ch.52-0).

The antisymmetry is observed in the postgonites: in A-type, the large, posterior postgonite and strongly sclerotized, inward curved, anterior postgonite is present on the right side ( Fig. 6H ), while the small, posterior one and less sclerotized, dorsad curved, anterior one on the left side; but in B-type, vice versa.

Specimens examined. China: 4♂ (A-type) 6♂ (B-type) paratypes, Mt. Jizu, Binchuan , Yunnan, 1,840 m a.s.l., 17.viii.2000, H.-W. Chen leg. ( SEHU) . Thailand: 1♂ (A-type), above Sangwal, Doi Suthep , Chiang Mai, 1,250 m a.s.l., 25.vii.2008, H. Bänziger leg. ( SEHU) .

Distribution. China (Yunnan), Thailand *.
