Synthetic description

Literna View in CoL is an African genus, described long ago in a very brief manner by Stål (1866), making it impossible to currently determine the species with his original publication. Most of its species are present in Madagascar. Lallemand proposed a refined description of this genus in 1912 based on the general body shape and wing venation ( Lallemand 1912). He updated his description in 1949 by adding genitalia characters for males and females, but they remained too general to qualify them as characteristic for this genus ( Lallemand 1949). The male genitalia have been described for only three species: L. altipeta Lallemand & Synave, 1952 View in CoL ; L. muscophila Lallemand & Synave, 1952 View in CoL and L. pauliani Lallemand & Synave, 1952 View in CoL ( Lallemand & Synave 1952). Hence, the description of the male genitalia for this genus is not presented in this publication. Moreover, some species, such as L. callosipenis ( Signoret, 1860) , seem to show morphological characters similar to the species now assigned to the new genus Soulierana Bucher & Bouteille gen. nov. Nevertheless, types-specimen(s) were not consulted during this study and as a result, no taxonomic revisions have been made for these taxa. However, the lack of information for the genitalia characters highlights the need for further taxonomic studies. A synthesis based on the older descriptions for the Malagasy species is presented below:

HEAD. In dorsal view ( Fig. 5A View Fig ), head as wide as long. Ocelli closer to each other than to compound eyes and generally separated by carina, barely visible or even absent in some species ( Fig. 5A, C View Fig ); a carina can be observed on frons. Postclypeus with large furrow which can extend over its entire length, but not necessarily; lateral edges of furrow usually diffused ( Fig. 5C View Fig ). In some species, such as L. callosipennis ( Signoret 1860) View in CoL , L. hovana Lallemand, 1949 View in CoL , L. madegassa Lallemand, 1949 View in CoL and L. signata Jacobi, 1917 View in CoL , lateral part of postclypeus marked with two carina and deep furrow. Postclypeus striated laterally.

THORAX. Anterior margin of pronotum strongly declining; presence of a few dimples on anterior part. Scutellum longer than wide. Hindlegs with one spine on metatibiae.

TEGMINA. Tegmina longer than wide ( Fig. 5A View Fig ) in tapered shape, except for L. ochracea Jacobi, 1917 View in CoL , which possesses oval tegmina strongly rounded on posterior part. One or few bumps on anterior part of tegmina.

MALE GENITALIA. Male genitalia with sterno-lateral plates.
