Diagnosis

Glyptapanteles rixi sp. nov. can be separated from G. mouldsi sp. nov. by having S5+ dark and T4–6 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. Glyptapanteles rixi sp. nov. can be separated from G. dowtoni sp. nov. by T4 being solidly dark (mostly pale in G. dowtoni sp. nov.) and T1 being orange to light brown (dark in G. dowtoni 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 Dr Mike Rix, who collected the type series, along with many other specimens, whilst kindly running a Malaise trap for this and other microgastrine projects at Toohey State Forest in Brisbane.

Description

Female

COLOURATION. Gena without a pale spot; labrum mostly dark or reddish-brown; scape colour in ventral half uniformly paler than flagellomeres; flagellomeres darkening distally; tegula pale or light brown; wing veins uniformly black or brown, or with small lighter area proximally; anteromesoscutum all dark; 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 orange to light brown; fore tibia pale yellow; mid tibia pale yellow; hind tibia darkening posteriorly; hind basitarsus light brown; T1 orange to light brown; 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 much paler; T3 mostly pale with darker patch in centre, mostly dark with paler lateral areas or uniformly brown; T4+ reddish-brown.

HOLOTYPE BODY MEASUREMENTS. Body length 2.0 mm; fore wing length 2.0 mm; antennal length similar to body length.

HEAD. Antennal flagellomere 14 length/width 1.75; antennal flagellomere 2 length/width 2.89–4.00; OOD/POD 1.63–1.86; IOD/POD 1.38–2.00.

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 shallow punctures scattered over most of area; 8–9 pits in scutellar sulcus; propodeum with median carina absent, shallow rugose sculpturing with some punctures in anterior corners or median carina absent, smooth in centre and postero-lateral corners, rugose elsewhere.

WINGS. Pterostigma length 0.52 mm; pterostigma width 0.19 mm; r 0.18 mm; 2RS 0.13 mm; 2m 0.11 mm; (RS+M)b 0.12 mm.

METASOMA. T1 lateral edges parallel for anterior ½ to ⅔ of length, then narrowing posteriorly; T1 mostly smooth, some punctures in posterior half; T1 length 0.32 mm; T1 width at posterior edge 0.08 mm; T2 an isosceles trapezoid, lateral edges straight or with curved lateral and anterior edges, becoming arch- or semicircle-shaped; T2 smooth and shiny; T2 length 0.15 mm; T2 width at posterior edge 0.32 mm; ovipositor slightly protruding from end of metasoma.

Male

As female.

Remarks

Glyptapanteles rixi sp. nov. constitutes BIN: BOLD:ADL2963 and is 3.69% (p-dist.) divergent from the closet BIN in the database (BOLD:AEI5416, an undescribed lineage from Australia, with two specimens).

Using the BOLD Batch ID engine, the COI barcode of the holotype is 3.5% different from the most similar COI sequence from an Australian specimen (AUGLY139-21; an undescribed lineage). All five of the type specimens were able to be sequenced for the wingless gene and share a unique barcode, which differs by a minimum of 5 bp from all other species with available sequence data.

Distribution

This species is currently known from Toohey State Forest in Brisbane, QLD.
