Platystomatidae

This is a speciouse family in the Oriental region, including Taiwan. LIN & CHEN (1999) listed 28 species from Taiwan, but Rivellia basilaris (WIEDEMANN) was erroneously left out from their list.

Our Platystomatidae material is numerous from Taiwan indeed, but I am not a specialist for this family. So below I give only a list of the species (altogether 19) represented in the HNHM. I mention only the number of the type specimens, number of the specimens identified by KÁLMÁN KERTÉSZ, and that of the recently collected material (we captured 29 specimens in 2000, and three specimens in 2003, i.e. the latter material is not significant.) .

Much to my regret, I have to note that there are labels written in Hungarian with the Rivellia specimens (with all species), which were on loan to a Japanese dipterist, saying “Az anyagot összetörve küldte vissza Hara” [The material was sent back by HARA broken into pieces]. That was not a result of shipping or postal disaster, but that of a particular way of handling museum specimens. First he broke down the head, legs, wings and abdomen of the specimens (indeed, we can find only the thorax on the pin), then he prepared the parts, and finally he put everything into a plastic microvial with a special glue, which has already been petrified by now. In cases when any parts were left out of vial by chance, he simply glued them to the outer surface of the microvial.
