Diagnosis

Glyptapanteles albigena sp. nov. is in the G. albigena species group and can be separated from other members of the group by the gena having a very large pale spot, covering at least a third of the gena height.

Etymology

The species epithet ‘ albigena ’ is from the Latin adjective ‘album’ (meaning ‘white’) and refers to the pale spot on the gena that is characteristic of this species and the broader species group.

Description

Female

COLOURATION. Gena with a pale spot; labrum pale; scape colour in ventral half paler than flagellomeres at proximal end; flagellomeres all black/dark brown; tegula pale; wing veins uniformly black or brown, or with small lighter area proximally; anteromesoscutum all dark, dark with significant orange patches on posterolateral corners or dark with very slight orange patches on posterolateral corners; scutellar disk and metanotum dark; propodeum dark; fore coxa pale yellow; mid coxa pale yellow; 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 or dark reddishbrown; T2 sclerotised area dark or dark reddish-brown; T2 lateral area dark, extends past indentation, but then pale; T3 dark, mostly pale with darker patch in centre or mostly dark with paler lateral areas; T4+ dark or reddish-brown.

HOLOTYPE BODY MEASUREMENTS. Body length 2.3 mm; fore wing length 2.4 mm; antennal length similar to body length.

HEAD. Antennal flagellomere 14 length/width 1.71–2.16; antennal flagellomere 2 length/width 3.00– 3.71; OOD/POD 1.67–1.71; IOD/POD 1.33–1.57.

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 or shallow punctures, space between punctures generally smaller than diameter of punctures; scutellar disk sculpturing with shallow or very shallow punctures scattered over most of area; 6–8 pits in the scutellar sulcus; propodeum with median carina faintly indicated for all of length or sometimes only in posterior half; rest of propodeum either smooth with some punctures in anterior half, or smooth with some shallow rugosity, or smooth with both punctures and some shallow rugosity.

WINGS. Pterostigma length 0.57 mm; pterostigma width 0.23 mm; r 0.16 mm; 2RS 0.15 mm; 2m 0.14 mm; (RS+M)b 0.09 mm.

METASOMA. T1 wedge-shaped, narrowing posteriorly for entirety of length, lateral edges straight (but not parallel); T1 smooth and shiny, some shallow scattered punctures on lateral edges or smooth and shiny, some shallow scattered punctures on lateral edges and posterior half; T1 length 0.36 mm; T1 width at posterior edge 0.07 mm; T2 an isosceles trapezoid, lateral edges straight; T2 smooth and shiny; T2 length 0.15 mm; T2 width at posterior edge 0.26 mm; ovipositor slightly protruding from end of metasoma.

Male

As female, but antenna slightly longer than body.

Remarks

Glyptapanteles albigena sp. nov. constitutes BIN: BOLD:ADL3908 and is 5.48% (p-dist.) divergent from the closet BIN in the database (BOLD:ABA6208; Glyptapanteles sanniopolus sp. nov.).

Using the BOLD Batch ID engine, the COI barcode of the holotype is 6.3% different from the most similar COI sequence of an Australian specimen (HYAT425-11 and HYAT424-11; Glyptapanteles sanniopolus sp. nov.). All specimens able to be sequenced for the wingless gene share a unique barcode that differs by a minimum of 1 bp from all other species with available sequence data.

Distribution

This species is known from the ACT and NSW and from southern QLD.
