Fig. 3 in Gallancyra gen. nov. (Phthiraptera: Ischnocera), with an overview of the geographical distribution of chewing lice parasitizing chicken

Fig. 3. Geographical distribution of four species of menoponid chewing lice parasitizing wild and domestic chicken (Gallus spp.). Each circle is divided into four sectors, representing the four louse species: upper left = Menacanthus cornutus (Schömmer, 1913); upper right = Menacanthus stramineus (Nitzsch, 1818); lower left = Menacanthus pallidulus (Neumann, 1912); lower right = Menopon gallinae (Linnaeus, 1758). Black sectors indicate that this louse species is known from this country, whereas hollow sectors indicate that we have found no published records of this species in this country. The presence of the four species of chewing lice in a country is based on the reports summarized in Table 1. Note that the menoponid species Amyrsidea powelli (Bedford, 1920) appears to be established on chicken in Nigeria (Fabiyi 1986, 1996), and that Menacanthus longiscleritus Naz & Rizvi, 2016, has been described from chicken in Pakistan. These are not shown on the map.
