- Calvariomorphus sp. (Figs 1G–H, 4E–G) Examined material. Female (ZMUC): “Pulo, \ Milu \ Galatea”. Description. Body small, TL 2.1 mm, TL/EW ~ 1.7, oval, light brown, legs and antennae lighter, yellowish, covered with, yellowish, semierect setae. Head strongly transverse, punctation sparse, punctures separated by ca. 1.5–2 diameters. Pronotum transverse, anterolateral and posterolateral angles right angled, lateral carinae almost straight, punctation sparse, similar to that on head. Angle between pronotum and elytra not marked in dorsal view. Scutellar shield subtriangular, impunctate. Elytra elongate, punctation stronger than on pronotum, dense, punctures separated by ca. 0.7 diameter. Apical portions of elytra with complex excitators: each excitator consisting of small depression with oval sucker-like structure surrounded by several pores, and adsutural tubercle with large pores in posterior portion and sucker-like structure in anterior portion, adsutural tubercle covered with long setae. Remarks. The specimen was collected in 1840s during the first Danish Galathea expedition in Nicobar Islands. Due to the fact that only a single female specimen of this interesting species is known, we have decided not to formally describe the new species.
