Abstract
Two new species of Stathmopodidae are described from Taiwan: Cuprina atayalica Shen & Hsu, sp. nov., reared from larvae on Microsorum brachylepis, and C. insolita Hsu & Shen, sp. nov., reared from larvae on Tectaria subtriphylla and T. harlandii. Diagnostic characters for both species are provided. Larval host plants and the biology of the immature stages of both new species are documented.
Highlights
The Stathmopodidae (Lepidoptera: Gelechioidea) represent a widespread group of moths which can be recognized by the characteristic rosettes of long and rigid bristles on the segments of the hind leg (Sinev 2015)
All adult moths were reared from immature stages collected from their host plants
The larval host plants of Cuprina atayalica and C. insolita belong to the families Polypodiaceae and Tectariaceae, respectively
Summary
The Stathmopodidae (Lepidoptera: Gelechioidea) represent a widespread group of moths which can be recognized by the characteristic rosettes of long and rigid bristles on the segments of the hind leg (Sinev 2015). We tried to investigate the hostplant associations of stathmopodid moths in Taiwan, using the comprehensive work for the Japanese fauna (Terada 2016) as reference. This strategy has proven effective, with a few unrecorded stathmopodid moths and new hostplant associations discovered during the investigation. Of the stathmopodid moths discovered from this survey, two species appear to conform to the diagnosis of the genus Cuprina Sinev, 1988, which is known from Far East Russia (Sinev 1988), Korea (Koo et al 2018), Japan (Terada 2016), and Sri Lanka (Meyrick 1913). The species diversity of the genus Cuprina has doubled to four species
