Mendes, Humberto Fonseca & Andersen, Trond, 2008, A review of Antillocladius Saether and Litocladius Mendes, Andersen et Saether, with the description of two new Neotropical genera (Diptera, Chironomidae, Orthocladiinae), Zootaxa 1887 (1), pp. 1-75 : 61

Litocladius mateusi Mendes, Andersen et Saether

Litocladius mateusi Mendes, Andersen and Saether, 2004: 74 , Figs 21–23 .

Material examined: Type material as in Mendes et al. (2004).

Diagnostic characters: The species can be separated from the two other members of the genus by absence of spines on third palpomere, wing veins and membrane bare, inferior volsella with rounded oral projection, and by having a distinct crista dorsalis.

Remarks: This species was originally described with two types of acrostichals. Reexamination of the holotype reveals that the anteriormost acrostichals had fallen off, but the size of the seta bases indicate that the acrostichals most probably can be subdivided into three groups: anterior strong decumbent, middle simple weak, and posterior scalpellate, as in the other two species included in the genus.

Biology and distribution: This species was collected among mosses on tree trunks and is described as male, female and pupa. The larvae could not be found, but is certainly terrestrial. The species is only known from the type locality in São Paulo State, Brazil .
