Diagnostic Notes
Hollis (1968). Differs from nominate subspecies (below) in the following ways: fastigium with forward angle more acute; fastigial foveolae narrowing more strongly anteriorly, frontal ridge flat and continually narrowing upwards; or weakly sulcate and with weak lateral carinulae, and junction with fastigium more angular; pronotum with "shoulders" of prozona more parallel in prozona and sometimes even with very weak lateral carinae in prozona; posterior margin of pronotum more rounded. Phallic complex with basal valves of penis less expanded laterally and not recurved.

General colouration differs from nominate subspecies in that ochraceous or green stripe along costal area of tegmen is usually complete; external area of hind femur without oblique fasciae; hind tibia with red colouration in apical 1/3rd only or not at all, and broadly separated from median black band by broad bluish grey band.

Description Aiolopus thalassinus thalassinus

Moderately rugulose. Antenna as long as combined lengths of head and pronotum, with 22-24 segments. Fastigium pentagonal, forward angle rounded, or subangular in specimens from Ethiopian and Oriental regions, moderately concave with well defined margins; fastigial foveolae trapezoid, normally slightly narrowing forward, about twice as long as maximum width; frontal ridge flat or slightly convex, sparsely pitted, lateral margins parallel except at apex where they converge slightly. Eye oval, about 1.5 times as high as maximum width and almost twice as high as length of subocular groove. Pronotum slightly saddle-shaped; metazona almost 1 2/3rds as long as prozona; latter constricted medially and with weak lateral "shoulders"; posterior margin of metazona obtuseangular; lateral plate of pronotum slightly higher than wide; mesosternal interspace almost square. Tegmen long, well exceeding tip of hind femur. Hind femur narrow, about 4 times as long as maximum width; hind tibia as long as or only very slightly shorter than hind femur, with 10 outer and 11 inner spines, inner apical spurs about 1.5 times as long as outer spurs; arolium half length of claw. Supra-anal plate, cercus and subgenital plate normal. Phallic complex with epiphallus having moderately developed outer lophal lobe; zygoma of cingulum with longer apodemes and poorly developed dorsal processes; basal valves of penis with lateral expansions strongly developed and recurved.

General colouration green or brown with ochraceous and black markings. Pronotum with or without median longitudinal ochraceous stripe and with or without ochraceous criss-cross pattern on dorsum, if without then dorsum unicolorously green or ochraceous and with blackish bordering colouration below "shoulders"; costal area of tegmen with interrupted ochraceous stripe, generally mottled and without clearly defined transverse bands; hind wing hyaline, sometimes weakly yellowish green basally and often with darkened apex; hind femur on upper outer area with 2 triangular black spots which continue onto outer area as incomplete oblique fasciae and on inner area as complete fasciae, apex of hind femur blackish with preceding complete or incomplete ochraceous ring ; hind tibia narrowly black basally, followed by broader ochraceous ring, apical 2/3rds normally reddish, red colouration separated from ochraceous ring by greyish ring.
