Type material.

Holotype: ♂, indonesia, West Java, Gunung Halimun N.P., Tea Plantation, Citalahab, 850 m, 6.77607N, 106.85401E, 20.VIII.2004, P. Hartmann (ZSM), Fig. 75 . Paratype: 1 ♂, the same label as for holotype (ZMS). Additional material (thisspecimen was determined as belonging the new species by photos and descriptive notes): 1 ♂, NE Sulawesi, 47 km WSW Kotamobagu, Dumoga-Bone N.P., Toraut (forest edge), 211 m, V.1985, G.R. Else, NHMUK 013380345 [ aff. insularis Astafurova det. 2019].

Diagnosis.

The new species most closely resembles Sphecodes insularis Smith, 1858, from which it differs by having an areolate punctate mesoscutum (with interspaces between punctures up to a puncture diameter in S. insularis ).

Description.

Wings with weak yellow-brownish darkening, veins and stigma brown; hind wing with the angle between basal (M) and cubital (Cu) veins ca. 70°, costal margin with seven or eight hamuli. Lateral preoccipital carina well developed. Male. (holotype, Fig. 75 ). Total body length 8.5-9.0 mm, fore wing 5.6-5.7 mm. Head black (Fig. 76 ); weakly transverse, ca. 1.15 times as wide as long; vertex elevated, distance from top of head to upper margin of a lateral ocellus ca. one and a half of lateral ocellar diameter as seen in frontal view and ca. two as seen in dorsal view; antenna short (Fig. 77 ), reaching posterior half of mesoscutum; F1 strongly transverse, 0.4 times as long as wide; remaining flagellomeres 1.2-1.3 times as long as wide; tyloids semi-oval across at most basal 1/2 of last flagellomeres; supraclypeal area weakly bulging; clypeus shining, densely punctate with the punctures (20-30 μm) separated by at most a half puncture diameter. Supraclypeal and paraocular areas dull, finely areolate-punctate (15-25 μm), but frons and vertex close to reticulate-rugose; gena shining, rugose with sparse short setae; paraocular and supraclypeal areas with dense plumose adpressed pubescence. Mesosoma black (Fig. 78 ); mesoscutum coarsely areolate-punctate (50-75 μm), medially closer to reticulate-rugose; mesoscutellum densely and coarsely punctate, medially with the punctures separated by at most a puncture diameter; hypoepimeral area reticulate rugose; mesepisternum and propodeal triangle (metapostnotum) roughly reticulate-rugose; mesepisternum with sparse and thin short setae; lateral parts of propodeum shining, close to striate. Metasoma (Fig. 80 ) distinctly punctate, T1 with minute (5-15 μm) numerous punctures; remaining terga coarsely punctate (15-25 μm / 0.5-2); marginal areas impunctate except on T1 which has fine and sparse punctures basally; sterna tessellate with shallow setae pores; gonocoxite dorsally without impression; gonostylus with triangular apical process (Fig. 79 ); T1-T3 and S1-S3 variable in coloration, partially red, remaining terga and sterna brownish.

Female unknown.

Etymology.

The species is named after the author’s daughter Darya Gayday and her husband Ilya Gayday, who recently married. It is to be treated as a noun.

Distribution.

Indonesia.
