Diagnosis

Glyptapanteles doreyi sp. nov. is in the G. arcanus species group and can be separated from the other members of the species group as follows:

Glyptapanteles doreyi sp. nov. can be separated from G. rodriguezae sp. nov. and G. ruhri sp. nov. by T1 being smooth and shiny, not having punctures that cover at least a third of the area of the posterior half of the tergite.

Glyptapanteles doreyi sp. nov. can be separated from G. goodwinnoakes sp. nov., G. erucadesolator sp. nov., G. lambkinae sp. nov., G. arcanus sp. nov. and G. vergrandiacus sp. nov. by the propodeum being less coarsely and less consistently, rugose sculptured across the anterior half of the propodeum. Glyptapanteles doreyi sp. nov. has the propodeum with shallow or strong punctures in the anterior half, the posterior half smooth or with shallow or strong rugose sculpturing and sometimes with a smooth area in the centre.

Glyptapanteles doreyi sp. nov. can be separated from G. wrightae sp. nov. and G. lessardi sp. nov. by the tegula being dark in colouration, the same colour or only slightly lighter than the mesosoma (the tegula in G. wrightae sp. nov. and G. lessardi sp. nov. is pale) the hind femur mostly dark (pale or light brown in G. wrightae sp. nov. and G. lessardi sp. nov.) and the indentation in the centre of the mesopleuron being strongly canaliculate. The indentation on the mesopleuron of G. wrightae sp. nov. and G. lessardi sp. nov. is smoother, not strongly canaliculate.

Etymology

Named for James Dorey, who collected the holotype specimen. EPF-J would like to acknowledge James’ collegiate sharing of specimens and his contribution to a successful field trip in northern QLD in 2019 that led to the collection of many important microgastrine specimens.

Remarks

Glyptapanteles doreyi sp. nov. has two wingless haplotypes (differing by a single base pair); however, as the COI divergence between specimens with the two different haplotypes is not consistent (i.e., one specimen has a COI sequence that is more closely related to specimens with the alternative wingless haplotype than to others) and the COI divergence among all specimens is not above 2%, we consider all specimens to be one species. One of the wingless haplotypes is shared with the species G. arcanus sp. nov. and G. goodwinnoakes sp. nov. and both barcodes only differ by 1 bp from the species G. vergrandiacus sp. nov. and G. lessardi sp. nov. This group of species is very closely related and would benefit from future, more detailed taxonomic work to ensure that they are not simply divergent populations of the same species. For this species hypothesis, we have made the decision to split this large clade into different species based on the COI barcode sequences being>3% divergent; however, we note that this is a hypothesis and is open to change with future work.

In the IQ-TREE analysis of the concatenated COI and wingless alignment, there are two clades within G. doreyi sp. nov. that differ, in their COI sequences, between 2.0% and 2.5%. The first clade (‘clade A’) contains seven sequences (AUMIC416-18, AUMIC409-18, AUMIC080-18, AUGLY044-21, AUMIC412-18, AUMIC390-18, AUMIC389-18). Specimen AUGLY044-21 has the same wingless haplotype as the specimens in the second clade within G. doreyi sp. nov. (‘clade B’) whilst the other six specimens share a wingless haplotype that differs by one base pair from that of AUGLY044-21. We have made the conservative decision to combine these two clades into a single species due to the COI divergence being borderline of what is often used in Microgastrinae , lack of clear morphological differences and the wingless haplotype of AUGLY044-21 being identical to that of the alternate clade; however, we provide images of a representative of both clades and note that future evidence (particularly host data) may end up splitting this species further.

Glyptapanteles doreyi sp. nov. constitutes BIN BOLD:ABY0421 (clade B) and BOLD:AEC8663 (clade A). Using the BOLD Batch ID engine, the COI sequence of the holotype is 2.6% different from the most similar COI sequence from an Australian specimen (MCCAA7675-20; an undescribed lineage).

Distribution

This species is currently known from eastern NSW and from the ACT.
