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 : 37

Antillocladius skartveiti Andersen et Contreras-Ramos

Antillocladius skartveiti Andersen and Contreras-Ramos, 1999: 150 , Figs 1–6 ; Mendes et al. (2004: 49).

Material examined: Type material as in Andersen and Contreras-Ramos (1999).

Diagnostic characters: The male can be separated from all other members of the genus by having several apical setae on the wing membrane; setose squama; costa moderately extended; acrostichals scalpellate, in the middle of scutum; no virga; anal point long, tapering, with strong lateral setae; and inferior volsella strongly set off, rectangular to rounded.

Distribution: The species is known from Ecuador.

Figures

FIGURES 1–2. Parsimony analysis of some Orthocladiinae genera and species with Brillia Kieffer, Diplocladius Kieffer and Propsilocerus Kieffer fixed as outgroup. Characters and character states as in text, matrix of characters as in Appendix 1. 1—strict consensus of shortest tree; 2—strict consensus of shortest tree after reweighting according to rescaled consistency index.

FIGURES 3–4. Parsimony analysis of some Orthocladiinae genera and species with Brillia Kieffer, Diplocladius Kieffer and Propsilocerus Kieffer fixed as outgroup. Characters and character states as in text, matrix of characters as in Appendix 1. 3—preferred tree based on strict consensus (Fig. 2) which is one step shorter than the tree after reweighting according to rescaled consistency index; 4—area cladogram based on the preferred tree.

FIGURES 5–6. Brooks Parsimony Analysis (BPA) of the species belonging to: 5—Antillocladius Saether; 6—Gravatamberus gen. n., Gynocladius Mendes, Saether et Andrade-Morraye, and Genus H sensu Epler.
