Colouration. Male: [specimen in ethanol] Dark brown to black: vertex dark brown; eyes red; antennal segments 8–10 progressively dark brown to black; pronotum, mesopraescutum and mesoscutum dark brown to black; fore and hind wings clear; fore wing veins R+M+Cu, R and R1 pigmented slightly darker brown than other wing veins; legs pale yellow-brown with dark brown to black dorsal infuscation; abdominal tergites 1–5 dark brown; sternites dark brown each with a transverse yellow-brown suffusion; proctiger, subgenital plate and parameres dark brown. Female: [specimens in ethanol] greenish yellow with brown markings; vertex pale yellow-brown with brown medial marking in vicinity of fovea; pronotum with pale medial marking; mesopraescutum with a pair of brown longitudinal markings; mesoscutum with 2 pairs brown longitudinal markings; mesoscutellum pale yellow; abdominal tergites brown each with a transverse pale greenish-yellow suffusion; sternites brown each with a transverse pale greenish-yellow suffusion; proctiger yellow-brown with brown apex; hooked setae tipped black; subgenital plate pale yellow-brown with apex dark brown. Structure. Measurements as in Tables 4–8 . Body large, compact ( Figs 91–94 ). Head ( Figs 95–96 ); vertex with weak medial suture, moderately sunk in vicinity of fovea; genal processes moderate in length, 0.36–0.45 times as long as vertex; antenna short, 0.82–0.88 times width of head, with 4–7 subapical rhinarium on segment 3, 3–5 on segment 4, 1–2 on segment 6 and a single subapical rhinarium on each of segments 8 and 9; segment 10 with a long bluntly rounded and a short bluntly rounded seta. Fore wing ( Figs 97–98 ) 4.26–5.44 times as long as head width, 2.51–2.76 times as long as wide, short, broad with slightly pointed apex; vein Rs evenly curved to costa, terminating well short of wing apex, considerably shorter than vein M, RsM: 0.78–0.84; medial cell short, smaller than cubital cell; veins M1+2 and M3+4 short, broadly diverging with corresponding low m1 cell value: 1.15–1.27; veins Cu1a and Cu1b short, each widely divergent with corresponding low cu1 cell value: 1.31–1.62; metatibia 0.89– 0.93 times as long as width of head, longer than metafemur, with 2 inner and 1 outer sclerotised apical spurs. Male terminalia ( Figs 125–126 ); proctiger very short, conoid, without expanded lateral lobes; subgenital plate broadly rounded; parameres ( Fig. 126 ) very short, broad with incurved sclerotised apices; distal portion of aedeagus moderate in length, with asymmetrical apical expansion ( Fig. 125 ). Female terminalia ( Fig. 133 ): proctiger short, triangular, posterior margin flat from lateral aspect and with weakly sclerotised apex; subgenital plate, triangular with tapering, weakly sclerotised apex; distal portion of proctiger with long pale setae and dense brush of hooked setae; subgenital plate with sparse long setae.

Scale = 1.0 mm. Comments. Myotrioza interioris sp. nov. can be distinguished by the following unique combination of characters: habitus as in Figs 91–94 , antenna with supernumerary rhinaria (4–7 rhinaria on segment 3, 3–5 on segment 4 and 1–2 on segment 6), fore wing short, broad with slightly pointed apex, fore wing veins R+M+Cu, R and R1 pigmented little darker than other wing veins, Rs considerably shorter than vein M ( Figs 97–98 ), female proctiger short, high with subapical dense field of hooked setae, valvula ventralis little curved, ventral profile of female subgenital plate flat ( Fig. 133 ), male proctiger conoid, with lateral lobes expanded distally, aedeagus long, paramere broad, blade-like with rounded apex ( Figs 125–126 ), host Eremophila , with eremean distribution. For diagnosis from closely related species, see Comments for M. desertorum sp. nov. Etymology. Named after interior , referring to the eremean distribution of the species. Host-plant association and distribution . ( Tables 2–3 ). Myotrioza interioris sp. nov. is recorded from an undetermined species of Eremophila at Credo Station Reserve and from Eremophila pantonii from Charles Darwin Reserve, Western Australia . It is one of 11 species of Myotrioza gen. nov. and 17 species of Triozidae recorded for Western Australia and is considered endemic to that state. It is one of 3 species of Myotrioza gen. nov. , namely M. darwinensis sp. nov. , M. interioris sp. nov. and M. pantonii sp. nov. from E. pantonii .
