Material examined.

Holotype female, dry pinned, deposited in BMNH (Hym Type 5.4813, barcode NHMUK010198566). Label data: "SULAWESI UTARA: Dumoga-Bone Nat. Pk, edge of rainforest, 0°34'N, 123°54'E. A.D. Austin June 1985, M.T."

Paratype female, dry pinned, deposited in CNC. Label data: "INDONESIA. Sulawesi Utara, Dumoga Bone Nat. Pk, Toraut IV.1985, JS Noyes, forest edge, MT."

Diagnosis.

Females of Paranastatus bellus are differentiated by the following combination of features: vertex rugose (Fig. 10); antenna mostly white except base of scape and club brown (Fig. 20); mandible tridentate; mesoscutum purple-brown medially, straw-yellow laterally and reticulate.

Description.

Female. Length: 2 mm.

Colour. Head with vertex dull black-brown (Fig. 10); temple brownish-green dorsally, blue-green laterally (Fig. 10); gena and face metallic blue-green (Fig. 20); frontovertex dull black-brown. Antenna mostly white, except base of scape and club brown (Fig. 20). Pronotum light brown; mesoscutum purple-brown medially, straw-yellow laterally; scutellar-axillar complex dark orange-brown; mesopleuron light brown to white anteriorly (Fig. 21). Legs white with mesofemur darkened along posterior apical edge and metafemur darkening to brown apically. Fore wing hyaline behind distal half of submarginal vein, but deeply infuscate basally, lightly infuscate patch behind base of marginal vein, and infuscate from behind postmarginal vein to wing apex; hind wing hyaline. Gastral tergites 1 and 2 white, remaining tergites dark brown; gastral sternites 1-4 white, remainder brown. Colour of setae on various body regions discussed in appropriate sections below.

Head. Vertex rugose (Fig. 10); temple coriaceous (Fig. 10); gena coriaceous except reticulate along malar sulcus (Fig. 20); face reticulate; frontovertex with blunt teeth projecting posteriorly towards vertex. Mandible tridentate. Vertex, temple and gena with sparse, very light brown setae; face with sparse white setae except scrobes bare; eyes with dense, short white setae.

Mesosoma. Pronotum coriaceous; mesoscutum reticulate, distinctly concave posteromedially; scutellar-axillar complex reticulate; mesopleuron coriaceous. Pronotum with white setae, setae longer along posterior edge; mesoscutum with many white setae; scutellar-axillar complex with few white setae along edges; mesopleuron with white setae anteriorly, remainder bare. Fore wing with dense, short brown setae; hind wing with relatively fewer short, light brown setae.

Metasoma. Entirely coriaceous with white setae ventrally, the setae very sparse dorsally and long at apex of gaster.

Male. Unknown.

Etymology.

From the Latin bellus, meaning handsome, in memory of Melanie Scallion’s dog Beau (French: handsome). This is an adjective in the nominative singular.

Distribution.

Sulawesi Island, Indonesia.

Biology.

Unknown.

Remarks.

Holotype deposited in the BMNH at the request of Dr. Andrew Austin, University of Adelaide, Australia. Both specimens are in poor condition. The head of the holotype is glued to the point, and the paratype is contorted with the body curled up on itself.
