Capellari, Renato Soares & Amorim, Dalton De Souza, 2009, Four new species of Paraclius Loew (Diptera: Dolichopodidae) from the Brazilian Atlantic Forest, and notes on the systematic position of Cheiromyia Dyte, Zootaxa 2274, pp. 51-61 : 55-58

Paraclius dicrophallus , sp. nov.

( Figs. 7–8 )

Diagnosis. First flagellomere almost rectangular, not pointed at apex; basal article about half the length of distal article of stylus. Three short black setae dorsally on proepisternum, with few scattered white setulae. Phallus divided mesally at apex into a pair of stems; hypandrium laterally forked into two stems, darker to the apex.

Material examined. Holotype 3: BRAZIL, Pernambuco, Recife, Parque dos Dois Irmãos, track 5, Malaise trap, 17–20.vii.2002, S. T. P. Amarante e eq. cols.

Description. Male. Body length, 3.3. Wing, 2.7 long, 0.9 wide. Very similar to P. amphiatheratus , sp. nov. by the features listed in diagnosis. Leg measures: I: 1.0, 0.8, 0.4, 0.1, 0.1, 0.1, 0.1. II: 1.2, 1.4, 0.5, 0.4, 0.2, 0.2, 0.1. III: 1.3, 1.2, 0.4, 0.6, 0.4, 0.3, 0.1. Hypopygium as in Figs. 7 and 8 . Sperm pump slightly enlarged, but greatly folded back over itself.

Etymology. From the Greek, “dikros” (forked) and “phallus” (penis), referring to the bifurcated shape of the phallus in this species.

Comments. This species superficially resembles P. p a re n t i, sp. nov. by the rectangular male first flagellomere, but can be recognized by the shape of both the phallus and hypandrium, as noted above.
