Diagnosis

Despite the large molecular divergence in both the COI and wingless genes (see remarks section), the only morphological character found to differentiate G. guzikae sp. nov. from G. kingae sp. nov. and G. austini sp. nov. is the femur being pale with a dark area posteriorly, rather than the femur being all dark as in G. kingae sp. nov. and G. austini sp. nov. However, we note that this subtle colour character may not be robust when further specimens are added to the dataset.

Etymology

Named for Dr Michelle Guzik, who has provided many years of mentorship and advice to EPF-J.

Material examined

Holotype AUSTRALIA • ♀; South Australia, Kangaroo Island ; -35.7533, 137.321; 17–24 Mar. 2011; G. Taylor, E. Kinnaird and R. Kittel leg.; Malaise trap MT3; Extraction97, BOLD: AUMIC524-18; SAMA 32- 46153 .

Description

Female

COLOURATION. Gena without a pale spot; labrum mostly dark; 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; mid coxa pale yellow; hind coxa dark; mid femur orange to light brown; hind femur orange to light brown; mid tibia orange to light brown; hind tibia darkening posteriorly; hind basitarsus light brown; T1 dark; T2 sclerotised area dark; T2 lateral area same colour as sclerotised area, or only slightly paler; T3 mostly pale with darker patch in centre; T4+ reddish-brown.

HOLOTYPE BODY MEASUREMENTS. Body length 2.1 mm; fore wing length 2.3 mm; antennal length slightly longer than body length.

HEAD. Antennal flagellomere 14 length/width 2.00; antennal flagellomere 2 length/width 2.57; OOD/ POD 2.17; IOD/POD 1.83.

MESOSOMA. Anteromesoscutum sculpturing with shallow to deep punctures, space between punctures a mixture of smaller than diameter of punctures and of similar size, smoother in posterior centre; scutellar disk sculpturing with only very shallow punctures, smooth and shiny; nine pits in scutellar sulcus; propodeum with median carina absent, very smooth and shiny, only very shallow punctures associated with setae.

WINGS. Pterostigma length 0.51 mm; pterostigma width 0.19 mm; r 0.13 mm; 2RS 0.14 mm; 2m 0.07 mm; (RS+M)b 0.08 mm.

METASOMA. T1 lateral edges parallel for entirety of length, posterior corners sometimes rounded at boundary with T2; T1 mostly smooth, some punctures in posterior half or smooth in anterior half, indistinct sculpturing in posterior half; T1 length 0.34 mm; T1 width at posterior edge 0.08 mm; T2

an isosceles trapezoid, lateral edges straight; T2 smooth and shiny; T2 length 0.12 mm; T2 width at posterior edge 0.14 mm; ovipositor slightly protruding from end of metasoma.

Male

Unknown.

Remarks

Glyptapanteles guzikae sp. nov. constitutes BIN BOLD:ADL2952 and is 6.86% (p-dist.) divergent from the closet BIN in the database (BOLD:ACL9923; an undescribed lineage, from New Zealand.

Using the BOLD Batch ID engine, the COI barcode of the holotype is 7.7% different from the most similar COI sequence from an Australian specimen (AUMIC291-18; Glyptapanteles austini sp. nov.). The type specimen was sequenced for the wingless gene and has a unique wingless barcode which differs by a minimum of 15 bp from all other species with available sequence data.

Distribution

This species is known from Kangaroo Island, off the coast of SA.
