Diagnosis

Glyptapanteles lambkinae sp. nov. is in the G. arcanus species group and can be separated from the other members of the species group, other than from G erucadesolator sp. nov., by having the propodeum with very coarse and strong rugose sculpting and T1 with strong sculpturing. Glyptapanteles arcanus sp. nov., G. vergrandiacus sp. nov. and G. goodwinnoakes sp. nov. also have coarse sculpturing on the propodeum (although to a lesser degree), but T1 is either smooth or with clear punctures (but not rugose sculpturing). It is noted, however, that all these species are morphologically very similar and identifications should be made with DNA barcodes. There was not a morphological character found to easily differentiate G. lambkinae sp. nov. from G. erucadesolator sp. nov., which are sister lineages in the current phylogeny ( Fig. 2 ); however, as the species differ by 2 bp in the wingless sequence and the COI barcodes are>6% divergent, we feel confident that these are different species.

Etymology

Named for Dr Christine Lambkin, who collected the type material and EPF-J and ARD thank her for all her support and help over the years.

Description

Female

COLOURATION. Gena without a pale spot; labrum reddish-brown; scape colour in ventral half uniformly paler than flagellomeres; flagellomeres all black/dark brown; tegula pale; wing veins uniformly reddish-brown; anteromesoscutum all dark 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 orange to light brown; fore tibia pale yellow; mid tibia pale yellow; hind tibia darkening posteriorly; hind basitarsus dark reddish-brown; T1 dark; T2 sclerotised area dark reddish-brown; T2 lateral area dark extends past indentation, but then pale; T3 mostly pale with darker patch in centre or mostly dark with paler lateral areas; T4+ reddish-brown.

HOLOTYPE BODY MEASUREMENTS. Body length 2.7 mm; fore wing length 2.5 mm; antennal length similar to body length.

HEAD. Antennal flagellomere 14 length/width 1.12–1.62; antennal flagellomere 2 length/width 3.00– 3.85; OOD/POD 1.43–1.71; IOD/POD 1.33–1.71.

MESOSOMA. Anteromesoscutum sculpturing with deep punctures, space between punctures a mixture of smaller than diameter of punctures, and of similar size; scutellar disk sculpturing with deep, sparse, irregularly spaced punctures, more common on anterior lateral edges; 10–11 pits in scutellar sulcus; propodeum with median carina absent, strongly rugose, sometimes with punctures in centre.

WINGS. Pterostigma length 0.62 mm; pterostigma width 0.21 mm; r 0.19 mm; 2RS 0.17 mm; 2m 0.11 mm; (RS+M)b 0.12 mm.

METASOMA. T1 lateral edges parallel for anterior ¾ of length, then narrowing posteriorly; T1 coarsely sculptured; T1 length 0.46 mm; T1 width at posterior edge 0.09 mm; T2 an isosceles trapezoid, lateral edges straight; T2 smooth and shiny; T2 length 0.16 mm; T2 width at posterior edge 0.27 mm; ovipositor slightly protruding from end of metasoma.

Male

Unknown.

Remarks

Glyptapanteles lambkinae sp. nov. constitutes BIN BOLD:ADL3041 and is 6.09% (p-dist.) divergent from the closet BIN in the database (BOLD:ADL3293; Glyptapanteles wrightae sp. nov.).

Using the BOLD Batch ID engine, the COI sequence of the holotype is 6.1% different from the most similar COI sequence from an Australian specimen (AUGLY141-21; an undescribed lineage, with a single specimen). All four five specimens were sequenced for the wingless gene, which is identical within the species and differs by a minimum of 2 bp from all other species with available sequence data.

Distribution

This species is known only from Lamington National Park in southern QLD.
