6) Phortica (Ashima) phyllochaeta ( Tsacas & Okada, 1983)

Amiota (Phortica) phyllochaeta Tsacas & Okada, 1983: 231 .

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

Diagnosis. Aedeagal sheath with two sclerotized, marginally serrated postgonites on anterior portion of left lateral lobe (“ Fig. 9 ” in Tsacas & Okada 1983).

Supplementary description (not repeating characters common to P. biclavata ). Supracervical setae 12–14. Dorsomedial, tentorial apodeme 2/5 as long as basal, parallel portion of dorsolateral, tentorial apodeme. Cibarial, medial sensilla 9–11 per side; posterior sensilla approximately 6 per side.

Specimen examined. Papua New Guinea: 1♂ paratype, Wau , Morobe district, 1,200 m a.s.l., 18.iii.1977, T. Okada leg. ( NSMT) .

Distribution. Papua New Guinea.

Remarks. This species closely resembles the foregoing species, P. biclavata , in having the aedeagal sheath with two marginally serrated postgonites on left lateral lobe and one anterior, large, marginally serrated postgonite and posterior, small, not serrated one on right lobe. However, these two species can be distinguished from each other by their diagnoses.
