19) Phortica (Ashima) mediarista Chen, 2012

Phortica (Ashima) mediarista Chen in Chen & Máca, 2012: 496 .

Diagnosis. Arista with arb = 8/7–8 (ch.5,6-0); longest, dorsal branch longer than longest seta on pedicel; apical, leaf-like expansion narrower than long, apically tapering and with long, awn-like projection.

Supplementary description. Supracervical setae approximately 16. Dorsomedial, tentorial apodeme slightly longer than 1/2 basal, parallel portion of dorsolateral, tentorial apodeme. Cibarial, medial sensilla 6–7 per side; posterior sensilla 6–7 per side. All tarsi with gray tarsomeres IV and V. Setulae on medial surface of abdominal sternites IV and V not so dense (ch.27,28-0). Setae on and/or near ventral margin of epandrium longer than others (ch.33-1). Surstylus with peg-like teeth (ch.37-0). Aedeagal, median rod less sclerotized (ch.58-2), looking like looped submedially [the corresponding portion labeled ‘aed a’ (aedeagal apodeme) in “ Fig. 10 ” of Chen & Máca 2012].

Specimens examined. Malaysia: holotype ♂, Mahua, Crocker Range, Sabah, 16.x.1999, M.J. Toda leg. (SEHU); 6♂, same data as the holotype, except 5.viii.2003 (SEHU) .

Distribution. Borneo (Sabah).

Remarks. This species first branched off in the tanabei subgroup (Fig. 1). The remaining three species form a cluster (BP = 82%) with two synapomorphies (Fig. 1): dorsomedial, tentorial apodeme ≥ 2/3 basal, parallel por- tion of dorsolateral, tentorial apodeme (ch.1-0; Fig. 7A); and setae on and/or near ventral margin of epandrium not longer than others (ch.33-0; Figs 6D, 7E).
