Abstract
Fivenew species of the genus Triotemnus from Morocco and Yemen are described. Triotemnus is a new genus of Scolytinae for the Yemen region. External morphology of the new species and all morphologically related species of the genus were studied. While the new species from Morocco are morphologically similar to the known species from the corresponding region, all three newly described species from Yemen, mainly two of them living in Socotra, are morphologically very different from all other known species of the genus. Geographical distribution and the probability of endemicity are discussed.
Highlights
The genus Triotemnus Wollaston, 1864, comprises 11 species distributed in the Palaearctic, Afrotropical and Oriental regions (Wood and Bright 1992, Bright and Skidmore 1997, 2002; Gatti and Pennacchio 2004)
Only two species, T. subretusus Wollaston, 1864 and T. ulianai Gatti & Pennacchio, 2004, occur in Europe, and five species are known from North Africa – T. antoinei Peyerimhoff, 1949, T. lepineyi Balachowsky, 1949 and T. longicollis Peyerimhoff, 1925 from Morocco, T. grangeri Peyerimhoff, 1919 from Algeria and T. subretusus Wollaston, 1864 from the Canary Islands
One species is known from Palaearctic part of India – T. scrofa Schedl,1975, from Uttar Pradesh
Summary
The genus Triotemnus Wollaston, 1864, comprises 11 species distributed in the Palaearctic, Afrotropical and Oriental regions (Wood and Bright 1992, Bright and Skidmore 1997, 2002; Gatti and Pennacchio 2004).
