Description. Adult
(
Figs 158–161
). Colouration. Male: [specimens in ethanol] Light yellow brown: vertex with small brown marking in vicinity of fovea; eyes pale reddish brown; antennal segments 8–10 progressively dark brown; mesopraescutum with a pair of orange brown anterior submedial markings; mesoscutum with a narrow medial and two pairs of orange brown submedial markings; fore and hind wings clear; fore wing veins equally pigmented brown; legs pale yellow-brown; abdominal tergites 1–5 dark brown; sternites brown to dark brown; proctiger, subgenital plate and parameres yellow-brown; anterior face of proctiger with brown infuscation; subgenital plate with a brown marking anteriolaterally; apices of parameres dark brown to black. Female: [specimens point-mounted] as for male except slightly darker; proctiger pale yellow-brown, with lateral brown infuscation and apex dark brown to black; subgenital plate pale yellow-brown, dark brown infuscation anteriorly and apex dark reddish brown.
Structure. Measurements as in
Tables 4–8
. Body short, compact (
Figs 158–161
). Head (
Figs 162–163
); vertex with weak medial suture, moderately sunk in vicinity of fovea; genal processes short, 0.37–0.43 times as long as vertex; antenna very short, 0.62–0.71 times width of head, with a single subapical rhinarium on each of segments 4, 6, 8 and 9; segment 10 with a bluntly rounded and a very short bluntly rounded seta. Fore wing (
Figs 164–165
) 3.40–4.01 times as long as head width, 2.53–2.96 times as long as wide, short, broad with rounded apex; vein Rs straight, slightly upturned distally, terminating short of wing apex, little shorter than vein M, RsM: 0.84–0.96; medial cell short, a little shorter than cubital cell; veins M1+2 and M3+4 short, broadly diverging with corresponding low m1 cell value: 1.27–1.50; veins Cu1a short, arched and Cu1b short, each narrowly divergent with corresponding high cu1 cell value: 0.74–1.00; metatibia 0.56–0.63 times as long as width of head, longer than metafemur, without sclerotised apical spurs. Male terminalia (
Figs 178–179
); proctiger conoid, with expanded lateral lobes; subgenital plate broadly rounded; parameres (
Fig. 179
) short, narrow, blade-like, evenly tapering to incurved sclerotised apices; distal portion of aedeagus moderate in length, with asymmetrical apical expansion (
Fig. 178
). Female terminalia (
Fig. 184
): proctiger high, triangular, posterior margin flat from lateral aspect and with blunt apex; subgenital plate, triangular with tapering, sharply pointed apex; distal portion of proctiger with a field of weakly hooked pale setae subapically and dense long pale setae dorsally; subgenital plate with sparse long setae.
Comments.
Myotrioza pantonii
sp. nov.
can be distinguished by the following unique combination of characters: habitus as in
Figs 158–161
, antenna with normal arrangement of rhinaria, fore wing broad with rounded apex, Rs little shorter than vein M (
Figs 164–165
), female proctiger with sparse field of weakly hooked setae, flat profile with elongate terminal upward inflection, valvula ventralis curved, ventral profile of female subgenital plate flat (
Fig. 184
), male proctiger conoid with medial lobe, aedeagus thin, elongate, paramere triangular with sharply pointed apex (
Figs 178–179
). For diagnosis from closely related species, see Comments for
M. darwinensis
