Diagnosis

Glyptapanteles austrinus sp. nov. is in the G. albigena species group and can be separated from most of the other members of the species group by the pale spot on the gena being small but clearly visible, T2 dark, the media carina completely absent, and the hind femur light brown to pale.

With the limited specimens available, there was not a morphological character found that easily differentiates G. austrinus sp. nov. from G. kittelae sp. nov. or G. aspersus sp. nov. The COI divergence between G. austrinus sp. nov. and G. kittelae sp. nov. is> 6%, whilst the divergence between G. austrinus sp. nov. and G. aspersus sp. nov. is> 8%, both of which are considerably large divergences at the species level for this subfamily of wasps. There are no available wingless sequences for G. austrinus sp. nov.

Etymology

The Latin adjective ‘ austrinus ’ means ‘southern’ and refers to the collection of this species near the southern tip of Australia, in Hobart, TAS.

Material examined

Holotype AUSTRALIA • ♀; Tasmania, Hobart, Kingston Beach ; -42.986, 147.317; 25–30 Apr. 2010; B. Ward leg.; BIOUG00995-H02, BOLD: HYAT371-11; TMAG F121367 .

Description

Female

COLOURATION. Gena with a pale spot; labrum pale; scape colour in ventral half the same colour or darker than flagellomeres; flagellomeres all black/dark brown; tegula pale; wing veins uniformly black or brown, or with small lighter area proximally; anteromesoscutum all dark; scutellar disk and metanotum dark; propodeum dark; fore coxa pale yellow or dark; mid coxa pale yellow or 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 reddish-brown; T2 sclerotised area dark reddish-brown; T2 lateral area same colour as sclerotised area, or only slightly paler or dark portion extends past indentation, but then pale; T3 uniformly brown; T4+ reddish-brown.

HOLOTYPE BODY MEASUREMENTS. Body length 2.3 mm; fore wing length 2.4 mm; antennal length slightly shorter than body length.

HEAD. Antennal flagellomere 14 length/width 1.22–1.50; antennal flagellomere 2 length/width 3.00– 4.00; OOD/POD 2.00–2.17; IOD/POD 1.83.

MESOSOMA. Anteromesoscutum sculpturing with only very shallow punctures, reasonably smooth; scutellar disk sculpturing with only very shallow punctures, smooth and shiny; 8–11 pits in scutellar sulcus; propodeum with median carina absent, only very shallow punctures associated with setae.

WINGS. Pterostigma length 0.57 mm; pterostigma width 0.27 mm; r 0.17 mm; 2RS 0.11 mm; 2m 0.12 mm; (RS+M)b 0.07 mm.

METASOMA. T1 wedge-shaped, narrowing posteriorly for entirety of length, lateral edges straight (but not parallel); T1 mostly smooth, some punctures in posterior half or smooth and shiny; T1 length 0.34 mm; T1 width at posterior edge 0.07 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 0.14 mm; T2 width at posterior edge 0.26 mm; ovipositor slightly protruding from end of metasoma.

Male

Unknown.

Remarks

Glyptapanteles austrinus sp. nov. constitutes BIN BOLD:ABA6213 and is 4.17% (p-dist.) divergent from the closet BIN in the database (BOLD:ADL4089; Glyptapanteles ferrugineus sp. nov.).

Using the BOLD Batch ID engine, the COI barcode of the holotype is 4.1% different from the most similar COI sequence from an Australian specimen (AUMIC042-18; Glyptapanteles ferrugineus sp. nov.). The holotype was able to be sequenced for the wingless gene, which differs by a minimum of 5 bp from all other species with available sequence data.

Distribution

This species is known only from Hobart in southern TAS.
