Lucasioides Kwon, 1993

Protracheoniscus (Lucasioides) Arcangeli, 1952: 298 , nomen nudum.

Lucasioides Vandel, 1969: 159 , nomen nudum.

Lucasioides Kwon, 1993: 142 . Type species: Porcellio (Lucasius) gigliotosi Arcangeli, 1927 .

Diagnosis (from Kwon 1993). Flat body granulated dorsally, gland pores absent. Cephalon with frontal line separated by groove, bearing well-developed median and lateral lobes. Epimeron of pereonite 1 bent outwards. Noduli laterales on pereonites 2̄4 farther from lateral margin than ones on pereonites 1 and 5̄7. Male pereopods 1̄4 merus and carpus with brush of long setae on sternal margins. Pleopodal exopods 1̄5 with Protracheoniscus - type pseudotrachea.

Remarks. Lucasioides is close to Protracheoniscus Verhoeff, 1917 and Mongoloniscus Verhoeff, 1930 . It can be distinguished from Protracheoniscus by the granulated dorsum and triangular median lobe of cephalon; in Protracheoniscus , the dorsal surface of body is smooth, and the median lobe of cephalon is less-developed. It differs from Mongoloniscus by the noduli laterales on pereonites 2̄4 farther from lateral margin than ones on pereonites 1 and 5¯7, and the epimeron of pereonite 1 bent outwards; in Mongoloniscus , the noduli laterales generally at the same distance from lateral margin, and the evenly convex pereonite 1 is not bent outwards.

Distribution. China, Japan and Korea.
