Webbia orbiculata ( Eggers, 1923) comb. res.

Xyleboricus orbiculatus Eggers, 1923: 213 .

Arixyleborus orbiculatus (Eggers) : Schedl 1958: 145.

Webbia orbiculatus [sic] (Eggers): Browne 1963: 57.

Arixyleborus orbiculatus (Eggers) : Wood & Bright 1992: 668.

Remarks. Xyleboricus orbiculatus was described from two specimens, one deposited in the Leiden Museum (now the Naturalis Biodiversity Centre), and one in the Museo Civico di Genova (now the MSNG). One of us (SMS) has examined the latter specimen, and all authors have examined photographs of it. It agrees with Eggers description, and clearly belongs in the genus Webbia to which it was transferred by Browne (1963), and not in Arixyleborus where it was placed by Schedl (1958) and Wood & Bright (1992). Here, we return it to Webbia . In order to fix the identity of the species, we here designate the specimen in MSNG as the lectotype. It bears the following labels: Sumatra / Si-Rambé/ XII.[18]90‒III.[18]91, E. Modigliani//Typus// Xyleboricus / n.g./ orbiculatus / n. sp./ cotype/ Eggers descr.1922// Syntypus / Xyleboricus / orbiculatus // Museo Civico/ di Genova// LECTOTYPE / Xyleboricus / orbiculatus / Eggers, 1923 / Sittichaya, Smith & Beaver/ 2023.
