Diagnosis

Glyptapanteles baylessi sp.nov. is closely related to the G. niveus species group, but can be differentiated by the deep punctures on the anteromesoscutum being denser (much less smooth space between punctures). Glyptapanteles baylessi sp. nov. has strong orange markings on the posterior anteromesoscutum that are significantly larger than in any of the other described species of Glyptapanteles in Australia.

Etymology

This species is named for Dr Keith Bayless, who collected the type series and also contributed a significant amount of critical additional material used in this study. We thank him for his continual willingness to share Malaise trap samples and his collegiate and open approach to taxonomic science.

Description

Female

COLOURATION. Gena without a pale spot; labrum pale; scape colour in ventral half uniformly paler than flagellomeres; flagellomeres all black/dark brown; 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 or white; mid coxa pale yellow or white; hind coxa dark or dark lightening distally; fore femur pale yellow; mid femur pale yellow; hind femur pale yellow or orange to light brown; fore tibia pale yellow; mid tibia pale yellow; hind tibia darkening posteriorly; hind basitarsus light brown, dark reddish-brown or dark; T1 dark; T2 sclerotised area dark; T2 lateral area same colour as sclerotised area, or only slightly paler or dark extends past indentation, but then pale; T3 uniformly brown; T4+ dark or reddish-brown.

HOLOTYPE BODY MEASUREMENTS. Body length 2.4 mm; fore wing length 2.4 mm; antennal length slightly longer than body length.

HEAD. Face densely sculptured, punctate reticulate; antennal flagellomere 14 length/width 1.63–2.25; antennal flagellomere 2 length/width 3.5–3.62; OOD/POD 1.13–1.71; IOD/POD 1.29–1.45.

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; 6–8 pits in scutellar sulcus; propodeum with median carina difficult to discern amongst sculpturing, propodeum strongly rugose, median carina absent and propodeum strongly rugose, or median carina very faintly indicated at posterior and anterior edges, propodeum strongly rugose.

WINGS. Pterostigma length 0.64 mm; pterostigma width 0.18 mm; r 0.13 mm; 2RS 0.11 mm; 2m 0.11 mm; (RS+M)b 0.08 mm.

METASOMA. T1 lateral edges parallel for anterior ¹/4 of length, then gently narrowing posteriorly, lateral edges often with slight curve; T1 smooth in anterior half, punctate reticulate in posterior half or smooth in anterior half, punctate reticulate to rugose in posterior half; T1 length 0.4 mm; T1 width at posterior edge 0.19 mm; T2 width greater than length, rectangular with rounded anterior corners; T2 with some shallow indistinct sculpturing or rugose; T2 length 0.13 mm; T2 width at posterior edge 0.36 mm; ovipositor slightly protruding from end of metasoma.

Male

As female, 6–9 pits in scutellar sulcus.

Remarks

Glyptapanteles baylessi sp. nov. constitutes BIN BOLD:ADL4626 and is 7.98% (p-dist.) divergent from the closet BIN in the database (BOLD:ADD5918, a BIN consisting of one specimen from Papua New Guinea).

Using the BOLD Batch ID engine, the COI barcode of the holotype is 8.3% different from the most similar COI sequence from an Australian specimen (AUGLY096-21; Glyptapanteles niveus sp. nov.). Sixteen specimens of the type series were sequenced for the wingless gene, which is identical across all specimens and differs by a minimum of 6 bp from all other species with available sequence data.

Distribution

This species is currently known from national parks south of Sydney, NSW.
