REMARKS. This species was described from a single male originating from southern Vietnam [ Pic, 1933] that I have examined only from the photographs. The male from northern Vietnam I have studied through the courtesy of Mr. Luboš Dembický (Brno, Czech Republic), is extremely similar to the holotype and is identified here as X. interrupta .

At the same time, one male from Borneo (from my collection), externally similar to X. interrupta , is actually a new species described below.

In the original description, Pic [1933: 10] noted that “ Lajoyeia n. gen. … Ce nouveau genre, établi pour l´espèce suivante, par la structure de ses antennes, se rappoche de Sebasmia Pasc. , mais le prothorax n´est pas rétréci en avant, les élytres sont moins allongés, enfin la forme des tibias intermédiaires est très particulière. Lajoyeia interrupta n. sp. …”. Without any doubt, this author was holding a specimen, initially devoid of the posterior legs, since he drew attention to the peculiar structure of only the mesotibiae. Gressitt and Rondon [1970] downgraded Lajoyeia to the rank of subgenus of the genus Xoanodera . However, the differences between Xoanodera s.str. and Lajoyeia , as well as their species composition must be reconsidered. If Lajoyeia nevertheless to accept as a subgenus, then it must include only X. interrupta and a similar new species described here and be characterized by the unique structure of the meso- and metatibiae of the male and some other features of these taxa. But this can be properly done only within the framework of a detailed revision of the morphologically very diverse genus Xoanodera and its division into various subgenera.

MORPHOLOGICAL NOTES. Body length 13.7–15.6 mm, humeral width 3.6–4.1 mm, thereby the holotype is the smallest .

The female is still unknown to me, but, unlike the male, it must have all tibiae without modifications.

Genitalia as in Figs 10, 12, 18, 21.

DISTRIBUTION. Indochina: Vietnam, Thailand; the records in Borneo and probably in Sumatra [ Makihara, 1999; Holzschuh, 1999; Heffern, 2013] are to be attributed to the next new species.
