description: 4) Phortica (Ashima) efragmentata Toda, sp. nov.
(Figs 2, 3 D–G)
Diagnosis. Posterior piece of aedeagal median rod widely bifurcated (Fig. 3F); aedeagal free sclerite absent (ch.59- 0; Fig. 3F).
Description. Supracervical setae 18–19. Dorsomedial, tentorial apodeme 3/4 as long as basal, parallel portion of dorsolateral, tentorial apodeme.Arista with arb = 8/4 (Fig. 2A). Palpus with hollow-shaped sense organ (Fig. 2B). Cibarial, medial sensilla 12–17 per side; posterior sensilla 6–7 per side (Fig. 2C). All tarsi entirely yellow (Fig. 2G); fore tarsomere I as long as 3 succeeding tarsomeres together; mid one slightly longer than rest tarsomeres together; hind one as long as rest together. Aedeagal sheath ventro-apically with a pair of strongly sclerotized postgonites much smaller than bifurcated pieces of aedeagal median rod (Fig. 3F).
Measurements (holotype, in mm): BL (straight distance from anterior edge of pedicel to tip of abdomen) = 3.65, ThL (distance from anterior notal margin to apex of scutellum) = 1.56, WL (distance from humeral cross vein to wing apex) = 2.46, WW (maximum wing width) = 1.08.
Indices (holotype, in ratio): FW/HW (frontal width/head width) = 0.44, ch/o (maximum width of gena/maximum diameter of eye) = 0.08, prorb (proclinate orbital seta length/posterior reclinate orbital seta length) = 1.78, rcorb (anterior reclinate orbital seta length /posterior reclinate orbital seta length) = 0.91, vb (subvibrissal seta length /vibrissa length) = 0.30, dcl (anterior dorsocentral seta length/posterior dorsocentral seta length) = (n/a), presctl (prescutellar seta length /posterior dorsocentral seta length) = 0.52, sctl (basal scutellar seta length /apical scutellar seta length) = (n/a), sterno (anterior katepisternal seta length/posterior katepisternal seta length) = (n/a), orbito (distance between proclinate and posterior reclinate orbital setae/distance between inner vertical and posterior reclinate orbital setae) = 2.08, dcp (distance between ipsilateral dorsocentral setae/distance between anterior dorsocentral setae) = 0.24, sctlp (distance between ipsilateral scutellar setae/distance between apical scutellar setae) = 1.20, C (2nd costal section between subcostal break and R 2+3 /3rd costal section between R 2+3 and R 4+5) = 2.35, 4c (3rd costal section between R 2+3 and R 4+5 /M 1 between r-m and dm-cu) = 1.50, 4v (M 1 between dm-cu and wing margin/M 1 between r-m and dm-cu) = 3.03, 5x (CuA 1 between dm-cu and wing margin/dm-cu between M 1 and CuA 1) = 1.00, ac (3rd costal section between R 2+3 and R 4+5 /distance between distal ends of R 4+5 and M 1) = 3.88, M (CuA 1 between dm-cu and wing margin/M 1 between r-m and dm-cu) = 0.66, C3F [length of heavy setation in 3rd costal section/(length of heavy setation in 3rd costal section+length of light setation in 3rd costal section)] = 0.71.
Holotype. ♂ (SEHU), “ Ulu Gombak, Selangor, Malaysia, 8.xii.2013, M.J. Toda ”.
Distribution. Peninsular Malaysia.
Remarks. This species resembles P. afoliolata in having the small postgonites (Fig. 3 F–H), but can be distinguished from it by the diagnostic characters.
Etymology. Referring to the lack of free sclerite within aedeagal outer membrane.
