Diagnosis

Glyptapanteles eburneus sp. nov. is in the G. eburneus species group and can be separated from G. foraminous sp. nov. by having T2 pale, the same colour as T1 ( G. foraminous sp. nov. has T2 dark). Additionally, the wingless sequences of the two holotype specimens are distinct and differ by 5 bp.

Etymology

The species epithet ‘ eburneus ’ is a Latin adjective for ‘ivory’ and refers to the pale colouration of T1–2.

Material examined

Holotype AUSTRALIA • ♀; New South Wales, Royal National Park. south end, Lady Carrington Drive Rainforest ; -34.1482, 151.031; 24 Nov. 1996; A.D. Austin leg.; Extraction 439, BOLD: AUMIC274-18; AM K.517935 .

Description

Female

COLOURATION. Gena without a pale spot; labrum pale; scape colour in ventral half uniformly paler than flagellomeres; flagellomeres darkening distally; tegula pale; wing veins uniformly black or brown, or with small lighter area proximally; anteromesoscutum dark with significant orange patches on posterolateral corners; scutellar disk and metanotum dark; propodeum dark; fore coxa pale yellow; mid coxa pale yellow; hind coxa pale yellow; fore femur pale yellow; mid femur pale yellow; hind femur pale yellow; fore tibia pale yellow; mid tibia pale yellow; hind tibia darkening posteriorly; hind basitarsus light brown; T1 pale; T2 sclerotised area pale; T2 lateral area same colour as sclerotised area, or only slightly paler; T3 pale; T4 pale with dark patch in centre, then darkening posteriorly on T5–7.

HOLOTYPE BODY MEASUREMENTS. Body length 2.7 mm; fore wing length 2.7 mm; antennal length slightly longer than body length.

HEAD. Face densely sculptured, punctate reticulate; antennal flagellomere 14 length/width 2.16; antennal flagellomere 2 length/width 3.62; OOD/POD 1.75; IOD/POD 1.75.

MESOSOMA. Anteromesoscutum sculpturing with deep punctures, space between punctures a mixture of smaller than diameter of punctures and of similar size; scutellar disk sculpturing with deep irregularly spaced punctures; nine pits in scutellar sulcus; propodeum with median carina present and complete, rest of propodeum mostly smooth.

WINGS. Pterostigma length 0.62 mm; pterostigma width 0.23 mm; r 0.18 mm; 2RS 0.16 mm; 2m 0.10 mm; (RS+M)b 0.10 mm.

METASOMA. T1 wedge-shaped, narrowing posteriorly for entirety of length, lateral edges straight (but not parallel); T1 mostly smooth, some punctures in posterior half; T1 length 0.4 mm; T1 width at posterior edge 0.12 mm; T2 with curved lateral and anterior edges, becoming arch- or semicircle-shaped; T2 smooth and shiny; T2 length 0.17 mm; T2 width at posterior edge 0.3 mm; ovipositor slightly protruding from end of metasoma.

Male

Unknown.

Remarks

Glyptapanteles eburneus sp. nov. constitutes BIN: BOLD:ADL5650 and is 2.4% (p-dist.) divergent from the closet BIN in the database (BOLD:ADL3303; Glyptapanteles foraminous sp. nov.).

Using the BOLD Batch ID engine, the COI barcode of the holotype is 2.3% different from the most similar COI sequence from an Australian specimen (AUMIC069-18; Glyptapanteles foraminous sp. nov.). The type specimen was able to be sequenced for the wingless gene, which differs by a minimum of 5 bp from all other species with available sequence data.

Distribution

This species is currently represented by a single specimen from Royal National Park, just south of Sydney.
