Description. Face, vertex and scutellum (Figs 7, 8) pale yellow testaceous, sometimes with darker brown mottling. Pronotum (Fig. 8) pale testaceous with brown mottling. Tegmen (Fig. 7) whitish with scattered brown fine mottling and larger diffuse brown markings at base and apex of clavus and on anterior margin at apex of costal cell, otherwise indistinct pale ocellations on remainder of tegmen.

Genitalia. Male: Subgenital plates ( Fig. 24BView FIGURE 24) narrow triangular tapering into apical process which is not well defined. Paramere ( Fig. 24FView FIGURE 24) with poorly developed preapical lobe; apical lobe curving gradually laterally, acute apically. Connective ( Fig. 24DView FIGURE 24) long with stem much longer than arms. Aedeagus, in posterior view ( Fig. 24CView FIGURE 24) with shafts diverging from base with posterior basal process fused to shaft on each side to about half shaft length, then extending dorsally as acutely pointed process; in lateral view ( Fig. 24EView FIGURE 24), shafts curved anteriorly with gonopore on anterior face and free portion of basal process extending about halfway to apex of shaft. Basal apodeme ( Fig. 24EView FIGURE 24), short directed at right angles to shaft. Female: unknown.

Etymology. The species name is derived from a combination of litus (Latin = coast) and ora (Latin = rim) reflecting the possible connective with coastal mangroves.

Comments. This species differs from all other species in the genus in the arrangement of the basal processes of the aedeagus and the relatively short connective arms compared with the length of the connective stem. The species is reasonably common along the eastern coastline of Queensland from North Queensland to Brisbane with two records from the Sydney region in NSW. The species has been collected in mangroves on four separate occasions and may be associated with this vegetation type.
