Diversity and abundance of Lepidoptera populations in the Theniet El Had National Park (Algeria).

An inventory of Lepidoptera in the Theniet El Had National Park (PNTEH), Algeria, revealed 86 taxa, both butterflies and moths. The specimens were collected in 68 localities distributed over ten cantons within the park in the period 2015-2017. A preliminary faunistic list is compiled as a base-line contribution to the study of adult Lepidoptera in this park.

Slender-horned gazelle (Gazella leptoceros), a new host for Tricholipeurus balanicus (Phthiraptera: Ischnocera: Trichodectidae).

This study was performed to provide information on Tricholipeurus balanicus (Werneck 1938) detected on slender-horned gazelles (Gazella leptoceros) (Cuvier 1842). Four slender-horned gazelles kept in the El Hamma Zoological Garden in Algeria were examined for lice in April 2015. Three of the four gazelles were infested with lice; of 37 lice collected from the infested animals, 14 were females, 16 were males, and 7 were nymphs.
