Algumas especies novas de Mallophaga (Trichodectidae)

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

“…Similarly to other lice, Tricholipeurus species are host-specific; however, some Tricholipeurus species have been found on other host species of the same or different host genera (14). T. longiceps (Rudow, 1866) is found on the Arabian gazelle (G. arabica), T. cornutus (Gervais, 1844) on the dorcas gazelle (G. dorcas), T. spinifer (Hopkins, 1943) on Grant's gazelle (G. granti), and T. parkeri Hopkins, 1941 on Thompson's gazelle (G. thompsonii) (14), while no Tricholipeurus lice were recorded from slender-horned gazelle, while T. balanicus was described only from the blackbuck (Antilope cervicapra) (10). T. balanicus was found on the blackbuck in Texas, USA (16).…”

“…T. balanicus was found on the blackbuck in Texas, USA (16). There are only few studies on the morphological characteristics of these species (10,12). In our study, 16 males and 14 female and 7 nymphs were measured, and their total lengths were 1.90 mm, 1.84 mm, and 1.71 mm, respectively.…”

“…Louse specimens were collected from the back and hind legs of the gazelles. They were preserved in alcohol and cleared in 10% KOH for 24 h. There after, they were rinsed in distilled water for 24 h and kept first in 70% alcohol and then in 99% alcohol 24 h. They were mounted on slides, examined under a binocular microscope (Leica DM 750), and identified as T. balanicus (Werneck 1938) (Figure 1-8) using relevant literature (10,12).…”

“…Lice were mainly found on the back and hind legs of the gazelles. The lice were collected by a forceps, preserved in 70% alcohol, and cleared in 10% KOH for 24 h. Thereafter, they were rinsed in distilled water, transferred to 70% and 99% alcohol, mounted on slides in Canada balsam, examined under a binocular microscope, and identified as Tricholipeurus balanicus (Werneck, 1938 …”

“…Today, the genus Tricholipeurus Bedford, 1929 is represented by more than 20 species (5)(6)(7)(8)(9)(10)(11)(12)(13)(14). Ledger (15) reported 16 Tricholipeurus species from animals living in the south of Sahara.…”
