, 2 nymphs, 18 Mar 1987; site 304A, 1, 1, 29 Nov 1986.

Description of female. Coloration (after ca 5 years in alcohol). Ground colour of head pale brown, with brown markings as follows: dorsal to eyes, across back of vertex and each side of median epicranial suture; broad patch centrally on frons; postclypeal striae converging towards midline. Antenna, labrum and two apical segments of maxillary palp dark brown. Ocelli pale, with black centripetal margins. Eyes black. Fore wing (fig. 66) with pattern of hyaline and brown areas. Hind wing (fig. 67) with brown tinge. Thorax and legs dark brown. Abdomen cream with terminal segments brown.

Morphology. IO:D = 2.7. Median epistomal suture distinct. Labrum: stylets spiculate; distal margin with 5 sensilla; internal sclerotisation present. Lacinia broad, flat, expanded preapically on one side, with apical denticles. Setae on flagellar segments short, uniform. Distribution of placoid sensilla: 2 small at base of f 1, 1 at apices f 4, f 6 and f 10, short filament on latter two placoids. Apex of distal segment narrowing, bluntly rounded. Head and thorax glossy. Mesothoracic precoxal suture absent. Setae on fore wing (fig. 66) in single rank, short and slanting distally; vein cu 2 setose. Abdomen with two ventral eversible vesicles. Epiproct (fig. 68) semicircular, setose. Paraproct (fig. 68) with round field of 16 trichobothria. Subgenital plate (fig. 69) uniformly setose, with pair of anteriorly diverging pigmented arms. Gonapophyses (fig. 70). Glandular area of spermathecal duct long (fig. 71), sac moderately large and sclerotised.
