( Fig. 1 , 2 & 3 )

Type Material. Holotype : M. PHILIPPINES, Mindanao Island, Compostela Valley, New Albay (7.343191, 126.112796). November 2016. Native collector. Paratype: F. PHILIPPINES, Mindanao, Lanao del Sur, Wao (7.657839, 124.709070) . April 2018. Native collector.

Description. General colouration from olive green to yellowish green [when dry], slightly shiny, with concolorous coarse punctuation (distance between punctures exceeding puncture diameter).

Head robust, rugose at base. Eyes greyish, pedunculate at base, globose, protruding beyond head profile, in contact with pronotum. Ocelli concolorous at base of eye peduncle. Labium reaching metasternum; bucculae low, surpassing antennifer tubercles.

Pronotum coarsely punctured, medial carina on anterior half of disc, one semi-circular depression on each side of the anteromedial carina. Marginal carina present, nearly reaching tip of humeral angle. Humeral angle produced. Scutellum coarsely punctured. Wing membrane concolour, semi-transparent, venation not clearly visible. Peritreme concolorous, slightly shiny. Evaporatorium mate, blackish near coxae, lighter coloured laterally, reduced to narrow strips anterior and posterior to rugae and peritreme ( Fig. 2a ). Legs concolorous with general colouration.

Abdomen with disc of connexivum slightly visible from above, finely punctured, concolourous. Spiracles rounded, concolorous. Abdomen base, next to spine, with blackish depressions behind metacoxae. Spine short, not reaching metacoxae. Connexival margins very slightly calloused. Male setose glandular patches near the centre, very small, restricted and in a clear depression of the abdomen ( Fig. 2b ).

Male genitalia ( Figure 1 c–i). Pygophore as in figures 1c–f, setose, cup-like. Posterolateral angles short, angulated, situated slightly above humps of ventroposterior rim. Dorsoposterior rim elevated, semi-circular. Genital plates enlarged, somewhat rhomboid-quadrangular, with smooth edges, exterior lateral side slightly concave. Ventroposterior rim concave at centre, with two humps, one on each side. Aedeagus (fig. 1i) simple, with one pair of apical, reduced, globular conjunctival, their apices not bifurcate. Median penial plates strongly sclerotized, united at base, U-shaped, pointy at apex and slightly widened in the middle. Vesica reaching about half of the medial penial plates, thinner at the base than in the apex, clubbed. Paramere (fig. 1h) robust and spatulate. Apex much wider than base and bearing an inwardly directed lobe.

Female genitalia ( Fig. 3 ). Vagina intima membranous, inconspicuous. Ductus receptaculi short. Vesicular area large, globose, with internal rod long and robust.Anterior annular flange small, strongly sclerotized and directed laterally. Pars intermedialis very slightly sclerotized. Capsula seminalis globular with posterior annular flange reduced but projected towards the capsula seminalis ( Fig. 3a ). Female genital plates as in figure 3b.

Measurements (in mm): total body length: 8.92/10.12, abdominal width: 5.29/5.56, length of head: 1.24/1.28, maximum width of head: 2.07/2.16, interocular distance: 1.09/1.18, interocellar distance: 0.76/0.73, pronotal length: 2.67/2.69, maximum pronotal width: 5.53/5.61, scutellar length: 4.05/4.19 (Prefrenal: 1.83/1.98) scutellar width at base: 3.5/3.51, legs (pro-, meso-, and meta- femora, tibiae, metatarsal segments I-II-III): 2.91/3.12, 2.58/2.83, 0.92/0.71-0.24/0.36-0.5/0.49; 3.26/3.17, 2.41/2.79, 0.87/0.74-0.22/0.34-0.52/0.42; 4.27/4.14, 3.66/3.98, 0.91/0.89-0.29/0.26-0.62/0.63. Antennomeres I: 0.47/0.48, II: 1.11/1.19, III: 1.25/1.38, IV: 1.64/-, V: 1.9/-, Rostromer I: 0.96/0.98, II: 1.25/1.44, III: 0.73/0.73, IV: 0.63/0.69.

Etymology. The specific epithet tagala refers to the Philippine language Tagalog [Pronounced as Tagalo].
