Diagnosis.

Eadya spitzer sp. n. can be distinguished from all other members of Eadya by the following combination of characters: Clypeus flanged at ventral margin, with two medial tubercles projecting outward (Fig. 14A ); frons with inter-antennal and lateral carina flanged (Fig. 14B ); occipital carina simple (Fig. 14B ); occiput simple; notaulus impressed towards anterior margin of mesoscutum, foveate at apex (Fig. 14C ); scutellar sulcus divided into many deep pits by ridge like longitudinal carinae (Fig. 14C ); sternaulus crenulate (Fig. 14D ); propodeum rounded in appearance from lateral angle (Fig. 13A ), without transverse carinae (Fig. 14E ), and not creating a distinct posterior face when viewed laterally; propodeal spiracle circular; head orange except for antenna, apex of mandible, and ocellar triangle black, median of clypeus brown (Figs 14A, B ); prothorax orange (Figs 12A , 13A , 14B ); hindwing infuscate with dark brown veins except for anal, basal, subbasal, and anterior half of discal cells hyaline (Fig. 13C ); legs black except for fore coxa and trochanter orange (Fig. 13A ); amino acid sequence (112-118) IRNFIGM (Fig. 15 ).

Description.

Female. Body length without abdomen 3.30mm. Abdomen 2.86mm. Ovipositor 1.17mm.

Color. Head orange except for antenna, apex of mandible, and ocellar triangle black (Figs 12A, B ; 13A, B ; 14A, B ), median of clypeus brown; prothorax orange (Figs 12A, B ; 13A, B ; 14A, B, C ); mesoscutum orange (Figs 12A, B ; 13A, B ; 14A, B ); mesopleuron black except for anterior dorsal margin orange (Figs 13A ; 14D ); metathorax black (Figs 12B ; 13A, B ; 14D, E ); forewing infuscate with dark brown veins except for anal, basal, and subbasal cells hyaline (Fig. 13C ); hindwing infuscate with dark brown veins except for anal, basal, subbasal, and anterior half of discal cells hyaline (Fig. 13C ); legs black except for fore coxa and trochanter orange (Figs 12A ; 13A, B ); abdomen black except for ovipositor orange (Figs 12C ; 13A ).

Head. Clypeus simple, smooth with scattered setae, flanged as ventral margin, with two medial tubercles projecting outward (Fig. 14A ); mandibles overlapping, dorsal tooth longer than ventral (Fig. 14A ); face finely punctate with associated setae (Fig. 14A ); frons rugose, inter-antennal and lateral carina flanged, starting at the toruli and reaching the ocellar triangle (Fig. 14A, B ); vertex smooth with scattered setae (Fig. 14B ); occipital carina simple (Fig. 14B ), reaching the hypostomal carina; hypostomal carina strongly flanged, reaching the mandible and bending around to the mandibular condyle; occiput smooth, normal (Fig. 14B ).

Mesosoma. Pronotum exposed in dorsal view (Fig. 14B, C ); pronope absent, subpronope absent, smooth except for a faint crenulate line extending laterally and rugulose sculpturing along the lateral posterior margin (Fig. 14B ); mesoscutum with median mesonotal lobe smooth (Fig. 14C ); notaulus impressed towards anterior margin of mesoscutum, foveate at apex (Fig. 14C ); scutellar sulcus divided into many deep pits by ridge like longitudinal carinae (Fig. 14C ); sternaulus crenulate (Fig. 14D ); propo deum rugose and pubescent, rounded in appearance from lateral angle, without transverse carinae and not creating a distinct posterior face when viewed laterally (Figs 13A ; 14E ); propodeal spiracle circular; coxa, trochanter, trochantellus, and femur covered in setae, tibia and tarsus pubescent; tarsal claws simple (Figs 12A ; 13A, B ).

Forewing. r-m curved slightly towards stigma before reaching the junction of 3RSa and 3RSb (Fig. 13C ).

Hindwing. R1a with three hamuli.

Metasoma. Metasomal tergite 1 petiolate, spiracle protruding as a tubercle at about the middle of the segment, dorsal and lateral surface punctate with associated setae (Fig. 14E ); ovipositor straight (Figs 12C ; 13A ).

Male. Unknown.

Host.

Paropsis charybdis , Paropsis aegrota elliotti Selman, 1983.

Variations.

Paratype with clypeus orange (Fig. 14A ). This variation may be the result of the DNA extraction process of the Holotype.

Distribution.

Tasmania.

Etymology.

This species is named in honor of Edwin Spitzer, the first author’s (RDR) late grandfather. This is a noun in apposition to the generic name in order to retain integrity of the surname Spitzer.

Remarks.

The paratype is for this series is badly damaged, missing both antennae, all six legs, and the abdomen excluding metasomal tergite 1. However, the specimen was photographed before destruction and can be seen in Figures 13A-C and 14A-E . This species is referred to as Eadya sp.2 in Peixoto et al. (2018).
