E-mail:[email protected] Abstract A synopsis of the subfamily Haplogleniinae Newman, 1853 (Neuroptera: Ascalaphidae) is presented. One new synonyms is proposed. Protidricerus palliventralis Yang, 1999 syn.n. is a junior synonym of Protidricerus elwesii (McLachlan, 1891). Two genera and eight species are redescribed and illustrated, and keys to the genera and species are presented. Key words: Owlfly, Idricerus, Protidricerus, new synonym Introduction The subfamily Haplogleniinae Newman, 1853 (Neuroptera: Ascalaphidae) has as its diagnostic character: eyes entire, without a transverse furrow. Nearly 100 species in 27 genera of the subfamily Haplogleniinae have been reported in the world, and are distributed mainly in South Asia, sub-Saharan Africa, Madagascar and the Americas (Tjeder 1992). To date, only a few species of Haplogleniinae have been recorded from northern hemisphere. No species of Haplogleniinae have been found in Australia. So far three genera are reported in Asia: Protidricerus, Idricerus and Ptyngidricerus. Before our study 5 species of Idricerus and 5 species of Protidricerus were reported in China. We found a synonym relationship among them. As a result, five species of Idricerus and four species of Protidricerus were recognized in China. Material and methods Terminology of wing venation follows Wang et al. (2003), while genitalia terminology follows Tjeder (1977). Photographs of morphological characteristics were taken with a Canon EOS 500D digital camera connected to an Olympus U-CTR30-2 microscope, using UV-C (Application Suite) applied software by United Vision Ltd. Photographs of habitus were taken by a Nikon COOLPIX4500 digital camera. All figures were processed in Adobe Photoshop CS5. All specimens examined are deposited in the Insect Collections of China Agricultural University (ICCAU), Beijing, China. Haplogleniinae Newman, 1853 Haplogleniidae Newman, 1853: 199.
