Cissidium adustipenne (Motschulsky, 1869)

Fig. 8

Not included in the following because the fragmentary nature of the material prevented description. A single specimen bearing what appears to be a Matthews label inscribed in ink “ Camptodium adustipenne ”, and with two printed labels “ Nagasaki, 13.ii–21.iv.81 ” and “ Japan, G. Lewis. 1910-320 ” exists in the BMNH acquired from the collector ( Fig. 8A ). The specimen was found in very poor condition missing head, elytra, pronotum and antennae ( Fig. 8B ) and has been reassembled and photographs taken ( Fig. 8 C–D). It is assumed that this specimen is the one described and figured by Matthews (1883), 1900) as “ found in Japan by Mr Lewis nr the Suwa Temple, 14 April 1881 …Mr Lewis has been fortunate enough to recover one of Col. Motschulsky’s lost genera. The insect taken by Mr Lewis agrees entirely with the characters given in his short and very unsatisfactory description, and also with his figure ”. A second specimen in BMNH labelled “ Camptodium Japan 1883 , 3005, Matthews coll. 1904-120 ”, being a slide of two legs and an antenna, may be related to this specimen. This slide was obtained by the Museum from the Mason collection and is mounted on one of Matthews’ distinctive hexagonal cards. (For more information about the Mason collection see Darby (1986 –on going).

A third specimen bearing a manuscript label “ Gombak. Sel ”, referring to Gombak, Selangor, Kuala Lumpur, Malaysia, and a pencil label “ adustipenne ” by Johnson is in MMUE. This has been dissected and the ventral characters are very different from those in the Japanese specimen above. This specimen has been given the name Cissidium visendum sp. nov. and is described below.
