Packard (1873) described Menopon picicola as a new species, based on ten lice taken from two species of woodpeckers of the genus Picoides-P. arcticus (Swainson, 1832) and P. dorsalis Baird, 1858-collected in Wyoming, U.S.A. in August 1872. Considering that (1) Packard (1873) neither designated a holotype nor a single type host, (2) his type material is most likely lost, and (3) no additional lice from either of those two species of Picoides have been reported in the literature, the taxonomic status of Menopon picicola has not been confirmed.Nothobranchius elucens, new species, from a seasonal habitat in the Aringa system of the Achwa River in the upper Nile drainage in northern Uganda, is described. It belongs to the N. rubroreticulatus species group, whose members are characterised by male coloration of anal and caudal fins with slender light blue subdistal band and slender dark distal band. read more Nothobranchius elucens is distinguished from all other members of the genus by the following characters in males body colouration golden-grey with brown scale margins creating irregular vertical stripes on trunk; anal fin yellow with brown spots proximally, with slender brown median band, followed by a slender light blue subdistal band and a slender black distal band; caudal fin brown proximally and medially, followed by a slender light blue subdistal band and a slender black distal band; dorsal fin golden with irregular brown stripes and narrow light blue subdistal band and with narrow black distal band. Furthermore, it differs from the closest known relative, N. taiti, also by the morphometric characters of having a smaller head length of 29.5-33.1 % SL; smaller prepectoral length of 31.2-33.9 % SL; greater head depth of 81-87 % HL; greater interorbital width of 43-49 % HL; and greater caudal peduncle length of 145-152 in % of its depth.A new species of Mauroniscus Bourgeois, 1911, Mauroniscus chilensis n. sp., from central Chile is described using external characters of the adult male and female including terminal segments of the abdomen and genitalia. The morphological differences of Mauroniscus chilensis n. sp. with M. maculatum Pic, 1927 are discussed.Two new species of the currently monotypic thiratoscirtine genera Ajaraneola Wesołowska Russell-Smith, 2011 and Nimbarus Rollard Wesołowska, 2002 are described from Uganda and Cameroon Ajaraneola pajakwandy sp. nov. (male) and Nimbarus nimbus sp. nov. (male), respectively. With the new species, previous diagnoses of the genera are re-evaluated and refined. The range of each genus is extended considerably Ajaraneola is reported from Uganda and Nimbarus from Cameroon for the first time.Calisto disjunctus hersheyi ssp. n. is described from western Cuba. Additionally, a dichotomous key including all described Cuban taxa of the herophile species group of Calisto is given together with illustrations of live specimens of most taxa.The specimens studied were collected with sweep net and pitfall in the forests, agro-forests, herbaceous fallows, and crop fields of 14 localities in the southern part of Cameroon, from August 2015 to February 2018. The results show that Heteracris hannai sp. nov. and Heteracris lecoqi sp. nov. differ from previously known species of the same genus by the pattern of coloration and the details or shape of the phallic complex. H. lecoqi sp. nov. is characterized by light brownish body; male cercus with flattened, downcurved and obtuse apex; lophus strongly curved; interlophal space with V shape; apodeme of cingulum bow, convergent, with V-shape; valve of cingulum in lateral view longer than apical valve of penis; ramus in ventral view joined. H. hannai sp. nov. is distinct to other species by brown to grey body; male cercus with apex rounded, curved inside; lophus curved; interlophal space with U-shape; apodeme of cingulum thick, slightly parallel, with U shape; valve of cingulum in lateral view hardly longer than apical valve of penis; ramus in ventral
