Diagnosis

Glyptapanteles goodwinnoakes sp. nov. can be separated from the other members of the G. arcanus species group by having the propodeum with generally coarser sculpturing than most species other than G. erucadesolator sp. nov., G. lambkinae sp. nov., G. arcanus sp. nov. and G. vergrandiacus sp. nov. a nd with T1 smooth (in all four of the previously mentioned species, T1 is either rugose or at least clearly punctured in the posterior half). It is noted, however, that all these species are morphologically very similar; limited specimens were available for examination and identifications should be made or corroborated with DNA barcodes.

Etymology

This species is named for Alison Goodwin and Roger Noakes, who ran a Malaise trap on their property near Bendemeer, NSW, from which a paratype of the species originates. It is a noun in apposition.

Description

Female

COLOURATION. Gena without a pale spot; labrum mostly dark; scape colour in ventral half uniformly paler than flagellomeres; flagellomeres all black/dark brown; tegula light brown; wing veins uniformly black or brown, or with small lighter area proximally; anteromesoscutum all dark, or dark with very slight orange patches on posterolateral corners; scutellar disk and metanotum dark; propodeum dark; fore coxa dark; mid coxa dark; hind coxa dark; fore femur pale yellow; mid femur orange to light brown; hind femur dark reddish-brown or orange to light brown; fore tibia pale yellow; mid tibia orange to light brown; hind tibia darkening posteriorly; hind basitarsus dark reddish-brown; 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 dark; T4+ dark.

HOLOTYPE BODY MEASUREMENTS. Body length 2.2 mm; fore wing length 2.1 mm; antennal length similar to body length.

HEAD. Antennal flagellomere 14 length/width 1.50–1.66; antennal flagellomere 2 length/width 2.62– 3.50; OOD/POD 1.71–2.00; IOD/POD 1.43–1.67.

MESOSOMA. Anteromesoscutum sculpturing with shallow to deep punctures, space between punctures a mixture of smaller than diameter of punctures and of similar size. Often smoother in posterior centre; scutellar disk sculpturing with shallow punctures scattered over most of area; 8–10 pits in scutellar sulcus; propodeum with median carina absent and propodeum strongly rugose, coarse sculpturing over most of propodeum, sometimes sculpturing clearly deeper in a ‘v’ shape with smooth anterior centre area.

WINGS. Pterostigma length 0.46 mm; pterostigma width 0.15 mm; r 0.17 mm; 2RS 0.12 mm; 2m 0.07 mm; (RS+M)b 0.08 mm.

METASOMA. T1 lateral edges parallel for anterior ½ to ⅔ of length, then narrowing posteriorly; T1 smooth and shiny, a few scattered punctures; T1 length 0.34 mm; T1 width at posterior edge 0.11 mm; T2 an isosceles trapezoid, lateral edges straight; T2 smooth and shiny; T2 length 0.17 mm; T2 width at posterior edge 0.12 mm; ovipositor slightly protruding from end of metasoma.

Male

Unknown.

Remarks

The wingless barcode for this species is shared with G. doreyi sp. nov. and G. arcanus sp. nov. and differs by 1 bp from the barcodes of G. vergrandiacus sp. nov., G. doreyi sp. nov. (second haplotype) and G. lessardi sp. nov. This group of species is very closely related and would benefit from future, more detailed taxonomic work to ensure that they are not simply divergent populations of the same species. For this species hypothesis, we have made the decision to split them into different species based on the COI barcode sequences being>3% divergent; however, we note that this is a hypothesis and is open to change with future work.

Glyptapanteles goodwinnoakes sp. nov. constitutes BIN BOLD:ADL3801 and is 3.69% (p-dist.) divergent from the closet BIN in the database (BOLD:AEI4383; an undescribed lineage, from Australia).

Using the BOLD Batch ID engine, the COI sequence of the holotype is 6.1% different from the most similar COI sequence from an Australian specimen (AUGLY141-21; an undescribed lineage, with a single specimen).

Distribution

This species has a very disjunct distribution, found in northern QLD and in central NSW. This likely reflects poor sampling rather than the true species distribution.
