Diagnosis

Glyptapanteles dowtoni sp. nov. is in the G. mouldsi species group and can be separated from G. mouldsi sp. nov. by having S5+ dark and T4–6 with at least some dark areas, or completely dark. Glyptapanteles mouldsi sp. nov. has the metasomal sternites all pale yellow other than the hypopygium, which is dark and T4–5 all pale/yellow. With the limited specimens available, there was not a morphological character found that easily differentiates G. dowtoni sp. nov. from G. rixi sp. nov. The wingless sequences of the three species differ by at least 6 bp and the COI differs by at least 4.3%.

Etymology

This species is named for Professor Mark Dowton, who collected one of the paratypes, along with many other specimens, whilst kindly running a Malaise trap for this and other microgastrine projects at Mt Keira, NSW.

Description

Female

COLOURATION. Gena without a pale spot; labrum reddish-brown; scape colour in ventral half uniformly paler than flagellomeres; flagellomeres darkening distally; tegula dark or pale; 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 pale yellow; hind femur pale yellow; fore tibia pale yellow; mid tibia pale yellow; hind tibia darkening posteriorly; hind basitarsus light brown; T1 dark; T2 sclerotised area dark reddish-brown, pale or orange to light brown; T2 lateral area same colour as sclerotised area, or only slightly paler or dark extends past indentation, but then pale; T3 mostly pale with darker patch in centre, uniformly brown or pale; T4+ reddish-brown, or T4 pale or pale with dark patch in centre; T5–7 darkening posteriorly.

HOLOTYPE BODY MEASUREMENTS. Body length 2.3 mm; fore wing length 2.3 mm; antennal length slightly longer than body length.

HEAD. Antennal flagellomere 14 length/width 2.00–2.16; antennal flagellomere 2 length/width 2.55– 3.83; OOD/POD 1.33–2.17; IOD/POD 1.11–1.67.

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 deep, sparse, irregularly spaced punctures, more common on anterior lateral edges, or with sparse punctures scattered over most of area; 9–12 pits in scutellar sulcus; propodeum with median carina absent, propodeum strongly sculptured, punctate reticulate to rugose, sometimes with smooth shining areas in posterior third.

WINGS. Pterostigma length 0.55 mm; pterostigma width 0.17 mm; r 0.18 mm; 2RS 0.15 mm; 2m 0.07 mm; (RS+M)b 0.11 mm.

METASOMA. T1 lateral edges parallel for anterior ½ to ⅔ of length, then narrowing posteriorly or with lateral edges parallel for anterior ¾ of length, then narrowing posteriorly; T1 smooth with shallow sculpturing along lateral edges or smooth and shiny, some shallow scattered punctures on lateral edges and posterior half; T1 length 0.38 mm; T1 width at posterior edge 0.11 mm; T2 an isosceles trapezoid, lateral edges straight or with curved lateral and anterior edges, becoming arch- or semicircle-shaped; T2 smooth, sometimes shiny, some indistinct sculpturing on postero-lateral corners; T2 length 0.14 mm; T2 width at posterior edge 0.19 mm; ovipositor slightly protruding from end of metasoma.

Male

As female.

Remarks

Glyptapanteles dowtoni sp. nov. constitutes BIN: BOLD:ADL2613 and is 1.61% (p-dist.) divergent from the closest BIN in the database (BOLD:AAH1085). BOLD:AAH1085 has two sequences within it (one of which is public: ASPNI556-09 from Papua New Guinea). This sequence was not included in the original analysis as it is not identified to genus level in BOLD. With the low p-dist. between these two BINs, we consider it possible that they may be the same species, which would mean that G. dowtoni sp. nov. is also present in Papua New Guinea. Morphological examination should be completed and a second gene should be sequenced to confirm.

Using the BOLD Batch ID engine, the COI barcode of the holotype is 2.8% different from the most similar COI sequence from an Australian specimen (AUGLY141-21; an undescribed lineage, with a single specimen). Fourteen specimens were able to be sequenced for the wingless gene and share a unique barcode that differs by a minimum of 3 bp from all other species with available sequence data.

Distribution

This species is currently known from southern QLD and eastern NSW.
