Diagnosis

Glyptapanteles niveus sp. nov. is in the G.niveus species group and can be differentiated from G.bradfordae sp. nov. by the presence of white distal flagellomeres (at least flagellomeres 10–11), a dark labrum and sparse punctures on the hind coxa ( G. bradfordae sp. nov. has the flagellomeres 10–11 dark, the labrum pale in colour and denser punctures on the hind coxa). Glyptapanteles niveus sp. nov. can be separated from G. cooperi sp. nov. by having a dark labrum ( G. cooperi sp. nov. has the labrum pale in colour).

Etymology

The species epithet ‘ niveus ’ is a Latin adjective meaning ‘snowy’ and refers to the white flagellomeres and white fore coxa, mid coxa, hind- trochanter and anterior metasomal sternites.

Material examined

Holotype AUSTRALIA • ♀; Queensland, Kuranda ; -16.8135, 145.6430586; 317 m a.s.l.; 12 Feb.–6 Apr. 2020; M.S. Moulds leg.; Malaise Trap EFJ2020MT36; Extraction1527, BOLD: AUGLY096-21; QM T250980 .

Description

Female

COLOURATION. Gena without a pale spot; labrum mostly dark; scape colour in ventral half the same colour or darker than flagellomeres; proximal nine flagellomere segments dark, at least some distal segments (flagellomeres 10–11) white (final five segments missing from type so colour unknown); tegula dark; wing veins uniformly black or brown, or with small lighter area proximally; anteromesoscutum dark with significant orange patches on posterolateral corners; scutellar disk and metanotum dark; propodeum dark; fore coxa white; mid coxa white; hind coxa dark; mid femur pale yellow; hind femur pale yellow; fore tibia pale yellow; mid tibia pale yellow; hind tibia light brown; hind basitarsus light brown; T1 dark; T2 sclerotised area dark reddish-brown; T2 lateral area dark extends past indentation, but then pale; T3 uniformly brown; T4+ reddish-brown.

HOLOTYPE BODY MEASUREMENTS. Body length 2.1 mm; fore wing length 1.8 mm; antennal length slightly shorter than body length.

HEAD. Antennal flagellomere 2 length/width 4.33; antennal flagellomere 14 missing; OOD/POD 1.57– 1.83; IOD/POD 1.17.

MESOSOMA. Anteromesoscutum sculpturing with very sparse, deep punctures; scutellar disk sculpturing with only very shallow punctures, smooth and shiny; seven pits in scutellar sulcus; propodeum with median carina present, in some parts difficult to differentiate from surrounding course rugosity.

WINGS. Pterostigma length 0.52 mm; pterostigma width 0.14 mm; r 0.1 mm; 2RS 0.11 mm; 2m 0.09 mm; (RS+M)b 0.07 mm.

METASOMA. T1 lateral edges parallel for entirety of length, posterior corners rounded at boundary with T2; T1 mostly smooth, some punctures in posterior half; T1 length 0.32 mm; T1 width at posterior edge 0.15 mm; T2 an isosceles trapezoid, lateral edges straight; T2 smooth, with some very shallow punctures in posterior half; T2 length 0.11 mm; T2 width at posterior edge 0.28 mm; ovipositor slightly protruding from end of metasoma.

Male

Unknown.

Remarks

Glyptapanteles niveus sp. nov. constitutes BIN BOLD:AEI1197 and is 3.55% (p-dist.) divergent from the closet BIN in the database (BOLD:ADD5918, a BIN containing one specimen (GMNGU216-16) from Papua New Guinea).

Using the BOLD Batch ID engine, the COI barcode of the holotype is 5.8% different from the most similar COI sequence from an Australian specimen (GMAQJ131-17; an undescribed lineage, with two specimens). The type specimen was sequenced for the wingless gene and the sequence differs by a minimum of 3 bp from all other species with available sequence data.

Distribution

This species is only known from Kuranda in northern QLD.
