Diagnosis

Japanese species of Loricula are recognised principally by the following characters: moderate to large size for microphysids (1.7–3.0 mm in total length, but micropterous female around 1.5 mm); basic colouration brownish, partly or largely reddish; male adult always macropterous, with rather long, delicate fore wings; female rounded, pot-shaped, either coleopteroid (fore wing roundly covering abdomen as in ladybirds of the Coccinellidae ; Figures 1 View Figure 1 (c) and 2(c,e)) or micropterous in wing form ( Figure 2 View Figure 2 (d)) or staphylinoid; antennal segment II usually longer than IV; female pronotum trapezoid or campanulate, with more or less projected posterior angle (except for micropterous form with truncate pronotum, modified mesoscutum and scutellum, and widely separated, ear-like hemelytral pads Figures 3 View Figure 3 (a), 6(d)); posterior margin of pronotum concaved in both sexes; scent gland with narrow but recognisable evaporative area ( Figure 4 View Figure 4 (i)); male fore wing membrane with a single, thick-veined cell and its posterior angle with a stub, or processus corial ( Figures 2 View Figure 2 (b), 3(f)); and male parameres more or less asymmetrical.

Distribution

Found extensively in the Palearctic Region.
