Paraclius parenti , sp. nov.

( Figs. 3–4 , 15–16 )

Diagnosis. First flagellomere almost rectangular, not pointed at apex; basal article of stylus about half the length of distal article. Two short black setae dorsally on proepisternum and scattered white setulae. Phallus without ornamentation except serrate ventral surface of apex; hypandrium harpoon-shaped in lateral view.

Material examined. Holotype 3, BRAZIL, Pernambuco, Recife, Parque dos Dois Irmãos, 1 3, track 3, Malaise trap, 17–20.vii.2002, S. T. P. Amarante e eq. cols. Paratypes: 1 3, same data as holotype, except track 5; same, but 1 3, track 3; same, but 2 3, track 1.

Description. Very similar to P. amphiatheratus except by the features listed in the diagnosis and the following details. Male. Body length, 2.9–3.1. Wing ( Fig. 16 ), 2.5–2.7 long, 0.9–1.0 wide. Male antennae as in Fig. 15 . Leg measures: I: 0.9, 0.9, 0.4, 0.1, 0.1, 0.1, 0.1. II: 1.2, 1.2, 0.5, 0.3, 0.2, 0.2, 0.1. III: 1.2, 1.3, 0.4, 0.5, 0.3, 0.2, 0.1. Hypopygium as in Figs. 3–4 . Sperm pump slightly enlarged and weakly folded back over itself

Etymology. This species is named after the French abbot and dipterist Octave Parent (1882–1942), who extensively contributed to the development of the taxonomy of Dolichopodidae .

Comments. This species resembles Paraclius dicrophallus , sp. nov. in the rectangular male first flagellomere, but can be easily separated from it by the shape of the phallus (simple, not furcated in P. parenti , sp. nov., Figs. 3–4 , and divided mesally at apex into a pair of stems in P. dicrophallus , sp. nov., Figs. 7–8 ) and of the hypandrium (harpoon-shaped in P. parenti , sp. nov., Fig. 3 , and laterally forked into two stems in P. dicrophallus , sp. nov., Figs. 7–8 ).
