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 : 96

Allocladius neobilobulatus (Paggi)

( Fig. 33 A–C )

Pseudosmittia neobilobulata Paggi, 1993: 172 .

Allocladius neobilobulatus (Paggi) ; Andersen et al. (2010: 14).

Material examined: ARGENTINA: Buenos Aires, Laguna de Lobos , 2 males paratypes, 15.vi.1989, A. Paggi ( ILLP). Other material as in Andersen et al. (2010: 14) .

Diagnostic characters: The two broad, large and lobe-like pars ventralis ( Fig. 33 A–C ) will separate the male imago from all other Pseudosmittia . The acrostichals also are stronger than normal and the accessory lobe of the inferior volsella is barely indicated. The pupa is very similar to that of the Holarctic P. nanseni (Kieffer) , but is distinguishable by having a papilla on the genital sac which is nearly twice as long as wide and more numerous spinules on the posterior sternal conjunctives.

The male and associated pupa is described in detail in Andersen et al. (2010: 14).

Distribution

The species is known from Argentina and Chile (Andersen et al. 2010).
