Recognized by the following combination of characters: M and Cu not fused basal of discal cell, subquadrate subbasal cell present, R+M apical of discal cell distinctly angled at branching point; eyes large; postocular region of head with weakly tumid genal area. Description. Body length 4.3mm Colour. As in Figures 10 and 11 . Body mostly reddish-brown with testaceous markings. Lobes of head reddishbrown; AI pale stramineous with three vague narrow testaceous annuli, one basal, one subbasal, one subapical, A2- A4 testaceous; labium pale stramineous with testaceous markings, basal 2/3 of LI testaceous, LII stramineous, LIII basally stramineous becoming testaceous. Pronotum excluding appendages entirely reddish-brown. Forecoxae mostly pale stramineous with vague testaceous basal annulus. Meso- and metacoxae testaceous. Basal portion of forefemora pale testaceous, remainder pale stramineous with two testaceous annulations, medial one small, subapical one large. Meso- and metafemora mostly stramineous-testaceous. Foretibia stramineous with testacous apical, medial, and subbasal annuli. Meso- and metatibia testaceous. Foretarsus mostly stramineous, pretarsus testaceous. Meso- and metatarsi testaceous. Forewings as in Figure 10 . Abdomen mostly testaceous, SI reddish-brown. FIGURE 10. Emesopsis monteithi . Forewing. FIGURE 11. Emesopsis monteithi , lateral view. Texture and Vestiture. Head dorsally covered in dense white wool-like pile interspersed with long upright setae; AI with long relaxed setae, AII-AIV with shorter appressed setae; LI with two dorsal (ventral when in repose) rows of recurved setae, LII and LIII with scattered shorter setae. Thorax covered dorsally and laterally with white wool-like pile interspersed with long setae, lateral tumid areas of anterior lobe of pronotum with tridentshaped nude areas, lateral-most lobe of trident basally isolated from remainder by narrow band of pile. Forefemora with mixture of short appressed setae and longer upright setae. Coxae, meso- and metafemora with long setae. Foretibia covered in shorter spine-like setae. Meso- and metatibia with spine-like setae basally becoming greatly reduced. Abdomen blanketed with short velutinous silken setae interspersed with much longer setae, SI with dense wool-like pile. Structure. As shown in Figures 10 and 11 . Postocular region slightly larger than anteocular region, latter elevated with depressed V-shaped area dorsally. Postocular region subglobose. Interocular groove deep, arching only slightly posteriorly. Labium strongly bent between LI and LII, LII strongly swollen, relative lengths 1:0.33:0.91. Pronotum constricted before midpoint; anterior lobe bilaterally divided by a deep pit in the disc, subglobose in dorsal view; posterior lobe almost two times longer than anterior lobe, disc with vague median longitudinal depression, posterior margin sinuate. Scutellum subtriangular. Metanotum U-shaped with short spine bent strongly posteriorly. Forecoxae elongate, cylindrical. Forefemora elongate, subclylindrical, posteroventral and anteroventral series similar in structure. Foretarsus 2-segmented, second segment 2 times larger than first. Meso- and metacoxae globose. Meso- and metafemora thin, elongate, cylindrical. Meso- and metatibia thin, elongate, cylindrical. Meso- and metatarsi 3-segmented, segments approximately equal in length. Distribution. This species is known from the northern tip of the Cape York Peninsula ( Fig. 6 ). Etymology. This species is named in honour of G. B. Monteith, who collected the type material for many of the new species described in this work.
