Chileanoscopus serrulatus Xue, McKamey & Zhang , sp. nov.

( Figs. 1 , 3 )

Description. Length (including wings): male 4.3–4.4 mm.

Crown yellowish, with brownish markings. Face stramineous, with brownish and black markings; lateral and base margin of anteclypeus black, apical region brown; base of antenna black ( Fig. 1 C). Female color similar to male, except face without more black markings ( Fig. 1 D).

Male abdomen with tergal apodemes broad, longer than one segment long ( Fig. 3 D).

Male genital. Style lateral lobe rounded, without hook or pointed ( Fig. 3 G). Aedeagal shaft slightly broad, obviously curved dorsally, nearly beyond dorsal apodeme, surface with irregularly serrate ( Figs. 3 E–F).

Material examined. Holotype: ♂, Chile, San Sebastian, nr. Cartagena, 1961. v.19, coll. N.L.H. Krauss ( USNM) . Paratypes: 15♂♂ 31♀♀, same data as holotype ( USNM) .

Etymology. The specific epithet refers to the serrate margins of the aedeagal shaft.

Remarks. This new species is similar to C. hichinsi ( Heller, 1969) in body color, but can be distinguished by the serrate aedeagal shaft that is obviously curved dorsally, and the male tergal apodemes slightly longer than the length of one segment.
