Ferrington Jr, Leonard C. & Saether, Ole A., 2011, A revision of the genera Pseudosmittia Edwards, 1932, Allocladius Kieffer, 1913, and Hydrosmittia gen. n. (Diptera: Chironomidae, Orthocladiinae) 2849, Zootaxa 2849 (1), pp. 1-314 : 246-248

Pseudosmittia carita sp. n.

( Fig. 92 )

Type material: Holotype male, SPAIN: El Rocio , 12.vii.1975, R. Kühbandner ( ZSM).

Diagnostic characters: The absence of a postcubital fork, combined with only 2 sensilla clavata, a tongueshaped inferior volsella and the long anal point without setae characterize the male imago.

Etymology: From the Latin caritus, lacking, devoid of, referring to the lack of numerous sensilla clavata or apical spine on the third palpomere and the lack of the postcubital fork.
