Zootaxa 's level of self-citation is also significantly different from most journals except for the TTJ Cretaceous Research , Journal of Palaeontology , and Systematic and Applied Acarology , and the Zoology journal Nematology ( p -value < 0.001). Influence of self-citations on JIF comparing all 123 journals is almost insignificant to boost this metric because most journals from the three categories (Entomology, Zoology and TTJ) have similar means of the ratio between JIF without self-citations and JIF for 2010–2018, except Shilap-Revista de Lepidopterologia , a journal devoted to butterflies and moths, Insects , published by Multidisciplinary Digital Publishing Institute (MDPI), and Zootaxa ( figure 6 ).
