E-mail: lpapp@zoo.zoo.nhmus.hu Abstract - The first records of the family Lygistorrhinidae (Sciaroidea) are given from Taiwan. A new genus Matileola, with its type species M. yangi sp. n. and Lygistorrhina chaoi sp. n. are described. With three figures. Key words - Lygistorrhinidae, Matileola, new taxa, Taiwan, Oriental region. Lygistorrhinidae is a small family of the Sciaroidea (Mycetophiloidea). Their family status had been debated for a period of time (e.g. TUOMIKOSKI 1966 and others) but most modern workers (e.g. THOMPSON 1975 to BECHEV 2000) accept Lygistorrhinidae as family. In the course of our collection trip to Taiwan in 2000, we found two lygistorrhinid specimens in light trap materials. Actually they were selected under a stereomicroscope from large quantity of noctuids and other moths and they were minuten-pinned on the site. One of the specimens represents a new species of Lygistorrhina SKUSE. The other specimen is a most peculiar one. It must belong to an undescribed genus. Otherwise these are the first records for the family Lygistorrhinidae from Taiwan. The type specimens are preserved in the collection of the Hungarian Natural History Museum (HNHM), Budapest. Matileola gen. n. (Fig. 1) Type species - Matileola yangi sp. n. Gender - Feminine. Description - Head much higher than long. Proboscis medium-long, twice as long as fore coxa. Antennae comparatively short, 14 flagellomeres are counted on our specimen. Mesonotum just slightly humped, scutellum rather small, mediotergite humped and bare. Pleural sclerites of thorax bare.
