Description: A species with a distinctive coloration and a broad, bluntly angled vertex that is about 1/4 wider between the eyes than the median length. The margin of the vertex usually lacks dark or white bands and is typically without dark markings; occasionally there is a black line on the margin. The vertex is only marked by a pair of broad longitudinal orange stripes, with two faint dark spots near the vertex tip inside the orange bands; these orange bands extends onto the pronotum, with a couple more smaller orange bands on either side. The female pregenital sternite is truncated/emarginate with a narrow incision in the middle that extends 2/3 of the way to the anterior margin. The male genital plates have broad bluntly rounded apexes that are divergent from one another. Adults are around 5.0 mm long. (DeLong 1941)

Comment: NOTE: Arundanus is a genus that consists of a number of species that look like one another. It is therefore important to get a clear, detailed picture of the underside to determine species identification; however, rubralineus has a somewhat distinctive color pattern.

HOWEVER, there is some variation among individuals in this species. Some females have V-shaped notches in the pregenital sternite; this notch is quite broad and deep, with the excavation extending halfway to the base. There is a black spot at the apex of the excavation. DeLong denoted these individuals as A. rubralineus var. excavatus and noted "it is not possible to determine [at the time] whether the female character is variable or if this may be a distinct species" (DeLong 1941). Collecting females of this species, especially those with this variation in the pergenital sternite, can help determine if there is a cryptic species present.

Status: Native
Global and State Rank: [GNR] [S2S4]
