Rucentra smetanai is a species of beetle in the family Cerambycidae (longhorn beetles). It was described by German entomologist K.-E. Hüdepohl, in collaboration with Aleš Smetana, in 1992.[1] It is known from Borneo.[2]

Taxonomy

Rucentra smetanai belongs to the genus Rucentra, which is placed in the tribe Apomecynini within the subfamily Lamiinae of the family Cerambycidae.[2] The genus Rucentra contains approximately 10 species distributed across Asia, making it one of the 121 genera of Apomecynini known from the Asian region.[3]

The species epithet smetanai honours Czech–Canadian entomologist Aleš Smetana, who was co-author of the original 1992 description and is widely recognised for contributions to Coleoptera taxonomy, including his co-editorship of the Catalogue of Palaearctic Coleoptera.[1]

Description

As a member of Cerambycidae, R. smetanai is a longhorn beetle, a group characterised by antennae that are typically as long as or longer than the body.[4] Longhorn beetles have antennal sockets located on low tubercles on the face, a defining feature of the family that distinguishes them from other beetles with elongated antennae.[4] Adult body lengths across the family range from 2 to 152 mm.[4]

As a member of tribe Apomecynini within the subfamily Lamiinae, R. smetanai belongs to a group characterised by small to moderate body size, divergent tarsal claws, and middle tibiae with a dorsal furrow.[5]

Distribution and habitat

Rucentra smetanai is known from Borneo, the third-largest island in the world, shared between Malaysia, Indonesia, and Brunei. Borneo is one of the major biodiversity hotspots in the world,[6] with over 1,300 longhorn beetle species catalogued from the island and more than 2,000 estimated to occur there.[7] The mountain ranges of north-eastern Borneo in particular host numerous endemic organisms,[6] reflecting the island's long history as a refugium for tropical forest biodiversity.

Ecology

Like other members of Cerambycidae, R. smetanai is expected to be a wood-boring insect in its larval stage. Cerambycid larvae typically develop within woody plant tissue, feeding and maturing inside the host before emerging as adults.[4] Adults of many cerambycid species feed on sap, pollen, or nectar.[8] The tropical rainforests of Borneo support extraordinarily high cerambycid diversity owing to tree species richness and the complexity of the forest structure.[9]
