Arixyleborus malayensis, is a species of weevil found in India, Sri Lanka, China, Japan, Malaysia, Vietnam and Indonesia. [1] This is the only species of Arixyleborus found in Japan and China. [2]
Body is about 2.1 mm long. Body stout and cylindrical. Head, pronotum and elytra are blackish brown. Legs and antennae are yellowish brown. Head globose with weakly convex frons. There are few scattered granules above the epistomal margin. Eyes are elongate and deeply emarginate. Antenna with 5-segmented funicle, a short scape and an obliquely truncate club. Pronotum sub rectangular. Basal margin is weakly bisinuate. Scutellum subrounded and distinctly shiny. Male is similar to female but with pale frons and a weak median depression above epistornal margin. In males, elytra is slightly shorter than pronotum. [3]
The protibia posterior face is inflated and granulate. Antennal club broader than tall. The posterolateral carina is costate. Pronotum lateral margin is distinctly costate where the anterior margin is elevated with a row of serrations. Elytral interstrial ridges are setose, with recumbent, hair-like setae. These interstrial ridges are denticulate. Elytral striae is strongly impressed whereas the elytral declivity is weakly shagreened. [4]
A polyphagous species, it has been recorded from several host plants. [5] Adults have been found in very small, cut trees of about 3 cm diameter. [6]
The host plants include: Albizzia lebbeck , Canarium indicum [7] [lower-alpha 1] , Dryobalanops oblongifolia , Eugenia , Myristica fragrans , Swietenia mahagoni and Vatica lanceifolia . [10]
Xyleborini are a tribe of ambrosia beetles, highly specialized weevils of the subfamily Scolytinae. Much of the ambrosia beetle fauna in Eurasia and the Americas consists of Xyleborini species. Some Xyleborini are notorious invasive species.
Xyleborus affinis, the sugarcane shot-hole borer, is a species of ambrosia beetle in the family Curculionidae. It is found on all continents with woodlands and is one of the most widespread ambrosia beetles internationally, primarily in areas with humid tropical climates like Florida. Like other ambrosia beetles, Xyleborus affinis is attracted to dead fallen logs in early stages of decay. Due to the presence of X. affinis on moist timber, this species is mistakenly believed to be the cause of tree death. However, there is insufficient evidence to support their presence as a causal factor. Rather, these beetles are believed to target and accelerate the decay process of trees that are already deteriorated and weak.
