Taxonomic revision of the endemic Bornean genera Anexodus Pascoe and Pantilema Aurivillius (Coleoptera, Cerambycidae, Lamiinae)

Abstract

The genera Anexodus Pascoe, 1866 and Pantilema Aurivillius, 1911 (Cerambycidae: Lamiinae: Morimopsini), both endemic to Borneo, are revised. Four species of Anexodus are recognized: A. aquilus Pascoe, 1886 (Malaysia: Sabah), A. sarawakensis Sudre, 1997 (Malaysia: Sarawak), A. syptakovae sp. n. (Malaysia: Sarawak), and A. tufi sp. n. (Brunei). Pantilema is a monotypic genus containing P. angustum Aurivillius, 1911 (Malaysia: Sarawak) which is known only from the holotype. For the first time, genital structures are studied in these genera. An identification key for the species of Anexodus is provided and their intraspecific morphological variability and distributions are discussed.

Leptomorphus sevciki sp. nov., a remarkable new wasp-mimicking fungus gnat from Brunei (Diptera: Mycetophilidae)

“…The insect fauna of Brunei is becoming increasingly more studied and new species are discovered regularly (see e.g. GABRIŠ et al 2017;GNEZDILOV 2015;JEŽEK et al 2015;KU-ŘAVOVÁ et al 2017a,b). However, the fungus gnat fauna (Diptera: Sciaroidea) still remains mostly unknown, with only several species of Diadocidiidae, Keroplatidae and Mycetophilidae described or recorded (see HIPPA & ŠEVČÍK 2010;PAPP & ŠEVČÍK 2005, 2011ŠEVČÍK & HIPPA 2010;ŠEVČÍK 2012;ŠEVČÍK & PAPP 2009;ŠEVČÍK et al 2014a;HIPPA et al 2016).…”
