Xylographella speciosa Lopes-Andrade sp. nov.

Diagnosis

The genus Xylographella was redescribed by Kawanabe & Miyatake (1996) in the work delimiting the tribe Xylographellini , and it is not necessary to provide another redescription here. The genus is closely related to Scolytocis , but differs mainly by the combination of the following features: (i) antennal funicle with five antennomeres; (ii) lateral margins of pronotum finely crenulated; (iii) pronotum and elytra with very coarse and dense punctation, the punctures being separated by a distance of one puncture width or less.

Comments

Since its description, the genus was formally known as monospecific and restricted to Japan. A new species is described here, based on specimens from the Philippines. Some species of Scolytocis may be confused with Xylographella due to their coarse pronotal and elytral punctation. However, they are easily distinguished by the diagnostic characters of the genera.

Figures

FIGURES 5–8. Prementum (pm) with labial palpi (l.p). Note that the apical labial palpomeres are enlarged (small arrows), and that the apex of prementum is acute in Xylographella and Scolytocis, and rounded in Syncosmetus and Tropicis (see big arrows). 5. Xyl. punctata Miyatake, lateral view. 6. Scol. paschoali sp. nov. 7. Sync. reticulatus Miyatake. 8. Trop. sexcarinatus (Waterhouse).

FIGURES 9–12. Female terminalia, showing the gonostyli (gs), gonocoxites (gc), baculi of basal gonocoxites (small arrows), paraprocts (pp), baculi of paraprocts (b.pp), proctiger (pt), and spiculum ventrale (sv). The baculi of proctiger are barely sclerotized, so they are not indicated. 9. Xylographella punctata Miyatake. 10. Scolytocis furieriae sp. nov. 11. Syncosmetus japonicus Sharp. 12.
