Etymology This species was named by a group of Aboriginal Summer School for Excellence in Technology and Science (ASSETS) high school students who participated in an entomology workshop in 2019 with the first author. The students chose to use an acronym for the group’s members (Tiah, Jayda, Pete, Erinn, Kaitlyn, Katelen, Izzy) with the ‘a’ for ‘ASSETS’ to form the species name. The sound ‘tj’ is commonly used in the Pitjantjatjara language, which is spoken in the north-west of South Australia where the species has been collected. It is pronounced like the ‘j’ in the English word ‘jar’. The species name is a noun in apposition.

MESOSOMA.Anteromesoscutum punctate reticulate, tending towards reticulate rugose on posterior lateral areas, punctures less dense in anterior centre; number of pits in scutoscutellar sulcus 9; scutellar disc with shallow but distinct punctures; maximum height of mesoscutellum lunules/maximum height of lateral face of mesoscutellum 0.6. WINGS. Fore wing length 2.7 mm ; length of veins r/2RS 1.2; length of veins 2RS/2M 1.2; length of veins 2M/(RS+M)b 1.0; pterostigma length/width 2.2. LEGS. Hind tibia inner spur length/metabasitarsus length 0.6. PROPODEUM. Medial carina indistinct in holotype , but clearly visible in male paratypes suggesting that female specimens may also have variable carina, holotype propodeum strongly rugose with some areas leaning towards reticulate rugose, but sculpturing less strong in some male paratypes . METASOMA. T1 length / T1 width at posterior margin 1.3; mostly parallel sided, slightly bulging at posterior curved corners, reticulate rugose to rugose in posterior half, sculpturing ‘messy’ and not easily categorise; T2 width at posterior margin /T2 length 2.5, trapezoid with curved lateral sides, messy rugose sculpturing, crenulate border on lateral sides and with T3 although less distinct in some male paratypes ; T2 length /T3 length 0.7; T3 sculpture smooth and shiny; ovipositor sheaths length/hind tibial length 0.1. Male As female but with slight variations in measurements, including antennal flagellomere 2 length/width 2.9; antennal flagellomere 14 length/width 3.0. Distribution Currently, this species is only recorded from arid South Australia , in the Lake Torrens and Great Victoria Desert regions. Host Unknown. Remarks This species constitutes the BIN BOLD:ADL5542, which has a maximum intraspecific distance of 1.28%, and a 2.41% distance to the nearest neighbour.
