Diagnosis. Body mostly yellow with slightly darker markings dorsally; no carinae between antennae, only broad rounded elevation; notauli present anteriorly but devoid of any sculpturing; faint vestige of admedial lines on dorso-anterior medial surface; suture line between metapleuron and propodeum not delineated by scrobiculate groove.

Description (female). Body length 5.1 mm; ovipositor 3.7 mm; body mostly uniformly yellow, with dorsal metasoma and distal sternites marginally darker colour, approaching dark brown colour of ovipositor sheaths.

Head width 1.2 mm, length 0.6 mm, height 0.9 mm; eye width 0.3 mm, length 0.4 mm, height 0.6 mm; interorbital distance 0.65 mm; median ocellus diameter 0.1 mm; distance between lateral ocelli and medial ocellus 0.1 mm; distance between lateral ocelli 0.2 mm; broad rounded elevation between antennae; ante-ocular pit not defined; antenna with 35 flagellomeres; clypeal width 0.3 mm, clypeal height 0.15 mm; malar space height 0.22 mm; distance from ventral eye margin to latero-ventral mouth margin 0.4 mm; labial palpomere 3 length 0.2x labial palpomere 4 length (lengths 0.02 and 0.1, respectively); labial palpomere 2 length 0.1 mm; posterior margin of head, when viewed dorsally, excavated (incursion 0.2 mm); posterior genal margin distinctly carinate, with no expansion ventro-posteriorly.

Mesosomal width 0.9 mm, length 1.9 mm; height 1.3 mm; pilosity short dorsally (0.04 mm), longer laterally (0.06mm), and sparse overall; subpronope distinct, carina on lateral margin only, not extending to anterior margin of pronotum, absent medially; notauli present anteriorly and smooth, absent posteriorly; faint vestige of admedial lines on dorso-anterior medial surface; scutellar sulcus obliterated by pin; propodeal surface smooth except for punctation associated with setae; suture line between metapleuron and propodeum not delineated by scrobiculate groove; propodeal spiracle round; difficult to see but hind coxal cavities appear closed to metasomal foramen; sternalus distinct scrobiculate curved groove; metapleuron smooth except weak punctation associated with setae; setal field absent.

Legs with all claws with large quadrate basal lobe; mid tibia with 2 apical spines and 4 preapical spines; preapical spines spaced along anterior surface in distal half of tibia; hind tibia with 2 apical and 2 preapical spines; preapical spines situated just basal to apical spines.

Both fore and hind wings slightly infuscate; fore wing maximum width 1.8 mm, length 5.2 mm; cell 1-Rs distinctly petiolate and triangular, width equal to length; petiole 0.1 mm in length; M+Cu entirely pigmented; hind wing maximum width 0.9 mm, length 4.1 mm.

Metasomal length 2.6 mm, maximum width 0.6 mm; dorsal surface smooth; T1 median area length 0.9 mm, anterior width 0.2 mm, posterior width (maximum) 0.5 mm; lateral margins of T1 sinuate in dorsal view; T2–3 with 1 complete transverse groove at T2–T3 boundary, slight lateral impressions present where T2 medial groove would occur.

Male. Unknown.

Holotype: ‘N. Queensland, Kuranda, 1,100ft., May 3–June 20, 1913, R.E.Turner. 1913–438’ (BMNH).

Comments. Therophilus martialis is easily recognised by being mostly yellow, having faint presence of admedial lines, and smooth notauli. The species is only known from the type locality in northern Queensland (Fig. 18A). The holotype is in relatively good condition except left flagellomeres are missing.
