Luteostriata abundans is a species of Brazilianland planarian in the subfamily Geoplaninae. It is a common species in human-disturbed areas in Brazil's southernmost state, Rio Grande do Sul.[1]
Description
Luteostriata abundans is a small to medium-sized land planarian with an elongate body and parallel margins. The largest specimens have a length of about 60 millimeters or more. The dorsum has a yellow tinge, varying from cream to dark yellow or light brown and is marked by seven longitudinal dark brown to black stripes. The ventral side is cream.[1] The presence of seven stripes distinguishes it from other members of Luteostriata.[2]
The numerous eyes are very small and hardly visible to the naked eye. They are distributed marginally on the first millimeters of the body and posteriorly become dorsal, covering the two most external stripes on each side. The eyes that cover the stripes are surrounded by halos, zones without pigmentation, which may be perceived as small clear dots.[1]
Its prostatic vesicle is elongated and non-bifurcated.[2]
Distribution
Luteostriata abundans is found in human-disturbed areas and borders of semi-deciduous and deciduous seasonal forests in the region surrounding the Porto Alegre Metropolitan Area, state of Rio Grande do Sul, Brazil.[1][3]
Diet
In the laboratory, the diet of L. abundans includes exclusively woodlice, which seem to constitute the main or only prey of most species in the genus Luteostriata.[2]
ワラジムシは、素早い筋肉の動きと粘着性の分泌物を用いて獲物を捕らえます。プラナリアは獲物に触れるとすぐに巻き付き、粘液を分泌し始めます。その後、獲物の上を滑るように移動して口の高さまで持ち上げ、咽頭を反転させてワラジムシの体節間を突き刺し、内容物を摂取し始めます。[ 4 ]
