Parischnogaster giglii Selis 2015: 131 , 137, fig. 14–18, ♂ —“ Filippine, Mindanao, Mt. Apo” (holotype male MSVI).

Material examined. PHILIPPINES: MINDANAO : Agusan, Esperanza , X.2014, 1 ♂ (MSVI); Agusan, Esperanza , XI.2014, 8 ♂ (6♂ MSVI, 2♂ MSNVE) ; Davao, Governor Generoso , II.2018, 1 ♂ ( MSVI) ; Davao, Kapatagan , VI.2016, 1 ♀ ( MSVI) .

Description of female. Body length 12.9 mm; fore wing length 10.3 mm.

Head 1.3× as wide as long in frontal view ( Fig. 46 ). Clypeus 1.1× as long as wide, strongly pointed apically,

weakly convex basally and very weakly concave apically in lateral view. Distance between ocelli shorter than ocellar diameter. Antenna clavate, expanding apically, antennal scape 2.8× as long as its apical width, F1 2.1× as long as its apical width, F2–F6 longer than wide, F7–F9 transverse, F10 bullet shaped, 1.3× as long as its basal width. Temples very short in dorsal view. Shallow longitudinal depression from ocellar area to occipital carina.

Mesoscutum as long as width between tegulae, strongly convex in lateral view, notaulices present as long distinct furrow, parapsidal sulci ill-defined. Scutellum strongly convex. Metanotum weakly convex, almost entirely vertical. Propodeum very weakly convex from base to apex in lateral view, longitudinal median furrow complete and deep from anterior to posterior margin, slightly expanded medially ( Fig. 47 ). Lateral faces of mesosoma slightly depressed posteriorly.

T1 7.3× as long as its maximum width, in lateral view almost regularly convex from base to apex, weakly depressed before apical bulge, in dorsal view with an apical strong bulge. T 2 in profile linear from base to apex, flattened.

Clypeus finely and densely punctate basally, with some scattered larger punctures. Frons and vertex weakly reticulate. Genae smooth and without punctures. Dorso-lateral portion of pronotum weakly and irregularly punctate, striate on ventral corners up to humeral tubercle. Mesoscutum regularly and finely striate, with a circular pattern. Scutellum and metanotum smooth, with some scattered shallow punctures. Propodeum striate on posterior face and lateral corners, lateral faces weakly and finely punctate. Mesepisternum dorsally densely and finely striate, smooth with some fine punctures ventrally.

Color. Head black; mesosoma and metasoma dark-brown, darker dorsally; following parts yellow: broad lateral bands on clypeus, inferior face of scape, whole dorsal face of pronotum, pronotal collar, spots at anterior corners of scutellum, anterior band on metanotum tightly incised medially, ventral half of posterior face of propodeum, triangular spot below base of wing on mesepisternum, lunate mark below transverse furrow, dorsal rounded spot on metaepisternum, spiracular spots on T2, antero-lateral spots on T3 and T5, longitudinal lateral lines on S2, four spots on S3, lateral ones larger, external face of fore legs from coxae to tibiae, external face of mid and hind coxae, apical spot on mid femora, external face of mid tibia; following parts reddish: apical third of clypeus, mandible, antenna, legs, ventral half of lateral faces of mesosoma, sides of T1–T2, sterna, sides of mesoscutum outside of notauli.

Distribution. Philippine Islands: Mindanao ( Selis 2015).
