( Figs. 23–29 ) Diagnosis. The male can be recognized by the following combination of characters: T2 briefly petiolate and with tergal organ reduced to a flattened area without conspicuous dense pilosity, notauli present as distinct furrows, segment 2–3 of mid tarsus lobed, antennal flagellum with setae between basal segments. Material examined. HOLOTYPE , ♂ labeled “ Philippines , Mindanao , Compostela Valley / II.2014 / Leg. local collector // Parischnogaster / albofasciata sp. nov. HOLOTYPUS ♂ / det.

Parischnogaster albofasciata Selis , sp. nov. , ♂. 23, Habitus in dorsal view. 24, Habitus in lateral view. 25, Head in frontal view. 26, Antenna in lateral view. 27, Apical half of fore wing. 28, Propodeum in posterodorsal view. 29, T2 in dorsal view. Description. Male. Body length 10mm ; fore wing length 8mm . Head 1.4× as wide as long in frontal view ( Fig. 25 ). Clypeus 1.2× as long as wide, weakly pointed apically, flattened basally and very weakly concave apically in lateral view. Distance between ocelli shorter than ocellar diameter. Mandible tridentate, inner tooth very short. Antenna clavated, expanding apically, antennal scape 2.7× as long as its apical width, F1 1.8× as long as its apical width, F2–F5 slightly wider than long, F6–F10 transverse, F11 bullet shaped, 1.2× as long as its basal width, F2–F6 distinctly flattened below ( Fig. 26 ). 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 clearly marked and long, adjoining lateral margins of mesoscutum. Scutellum strongly convex. Metanotum weakly convex, almost entirely vertical. Propodeum convex in lateral view, longitudinal median furrow complete from anterior to posterior margin, thin but clearly marked ( Fig. 28 ). Lateral faces of mesosoma depressed posteriorly, forming deep hairy depressions. T1 7.2× as long as its maximum width, in lateral view almost linear from base to apex, in dorsal view very weakly expanded apically. T 2 in profile almost linear from base to apex, tergal organ very rudimentary and reduced to a flat area ( Fig. 29 ). T7 broad and rounded apically. S7 strongly depressed on entire surface. Anterior lobe of segment 2 of middle tarsus expanded and pointed apically, segment 3 heart shaped. Hind femora strongly curved basally, then flattened for entire length. Hind tibiae weakly curved and flattened basally. Third submarginal cell of fore wing 1.5× as high as wide ( Fig. 27 ). Clypeus very densely and finely punctured. Frons densely covered in shallow small punctures. Genae smooth and without punctures. Pronotum smooth, striate only on ventral corners up to humeral tubercle. Mesoscutum regularly and finely striate. Scutellum and metanotum smooth, with some scattered shallow punctures. Propodeum striate on posterior face, lateral faces weakly and finely punctate. Mesepisternum dorsally densely punctate, very fine punctures forming irregular striae, impunctate ventrally. Color. Head black; mesosoma and metasoma brown, darker dorsally; following parts light yellow: circular marking encircling central dark spot on clypeus, ventral face of scape, pronotal collar, whole dorsal face of pronotum, extremely small spots between notauli, large lateral spots on scutellum, slightly incised anterior band on metanotum, triangular spot just below wings on mesepisternum, lunate mark below transverse furrow, dorsal rounded spot on metaepisternum, basal corners and apical half of posterior face of propodeum, anterior face of fore coxae, dorsal face of median and hind coxae, outer face of fore legs and median femora; following parts white: base of T4–T7, lateral spots on S2–S3. Female. Unknown. Distribution. Philippine Islands : Mindanao. Etymology. The specific name refers to the broad white bands on the metasoma.
