Physodera eburata Heller, 1923

Fig. 17 .

Heller 1923: 304 (Original: Physodera ; type locality: Los Banos (Luzon); lectotype deposited in SNSD); Csiki 1932: 1347 (catalogue); Jedlička 1963: 301; Shi et al. 2013: 41.

Material examined. Lectotype of Physodera eburata Heller , designated herein (SNSD), a female, "Los Banos / P.I. Baker"; " eburata / Typus" [red label]; "1920 / 3" [yellow label]; "Staatl. Museum für / Tierkunde, Dresden". ( Figs. 5 , 17 ); 1 female ( SNSD), " Samar Borongan, coll. W.Schultze "; " Coll. W. Schultze, Ankauf 1942"; " Staatl. Museum für Tierkunde, Dresden ".

Diagnosis. Body length 10.1–11.5 mm. Dorsal side black with metallic purple hue; pronotum unicolor ; elytra with a pair of ivory callosities on disc, callosity about 1/4 as elytron in length, placed in the middle of elytron, round in shape, strongly notched posteriorly. Tergum and sternum VII without distinct pattern. Antennameres 5–11 distinctly widened and flattened. Elytral third interval with two setigerous pores, the fifth with only one pore near base; apical margin truncated.

Together with P. bifenestrata and P. sciakyi sp. n., P. eburata can be readily distinguished from other species of Physodera by the presence of ivory callosities on elytra. These three species have differences in the shape of elytra callosities (round with a notch in P. eburata , and without a notch in P. bifenestrata and P. sciakyi sp. n.) and different distributions.

Male genitalia. Unknown.

Female genitalia. Not studied.

Distribution. Only known from the Philippines (Luzon, Samar). ( Fig. 65 )

Remarks. In the original literature, Heller (1923) indicated that this species has elytra dull in apical part, and shining in P. bifenestrata . However, after examined a "normal" specimen in the collection of SNSD, we found that the dull elytra of the lectotype is caused by deformation when emergence, and not a taxonomical character.
