Anacroneuria tucuman View in CoL sp. nov.

( Figs. 5-9 View Figs )

Material examined. Holotype ♂ and 1♂ paratype from Argentina, Tucuman Province, Horco Molle , 700 m, 15 January 1980, L. Stange ( FSCA) .

Adult habitus. General color pale yellow brown. Head with brown lappets and a diffuse spot forward of ocelli and a pair of small diffuse spots between lappets. Pronotum mostly brown but with pale lateral margins, a pale median band on the anterior half of the disk and a pale area incorporated within dark region in center of disk ( Fig. 5 View Figs ). Legs pale brown except for narrow dark brown band on distal end of femora. Wings pale, transparent; veins pale amber except for C and R veins which are very pale.

Male. Forewing length 12-14 mm. Hammer a low, almost transparent bubble-like structure ( Fig. 6 View Figs ). Aedeagal apex simple, but slightly offset from shoulders by a subtle notch ( Figs. 7-9 View Figs ); a pair of small membranous lobes occur on the posterior margins of the apical area and an inverted Y-shaped keel with long stalk occurs on the dorsum. In lateral aspect the sclerotized area bulges slightly and is offset from the pale keel. Hooks slender ( Figs. 7, 9 View Figs ).

Female. Unknown.

Larva. Unknown.

Etymology. The species name, used as a noun in apposition, is based on the Argentine province in which the type specimens were collected.

Diagnosis. Only three Anacroneuria species are currently known from the neighboring province of Salta [ A. arrazayalensis Orce ( Orce 2003) ; A. marshalli Stark ( Stark 2007) ; A. saltensis Froehlich ( Froehlich 2002) ] and only A. reedi (Navás) ( Navás 1919) , a species whose identity is in question ( Illies 1966), has been reported from Tucuman Province. The aedeagus of the new species is generally similar to that of A. saltensis but the keel in that species consists of a pair of parallel lines, the apex is not offset from the shoulders and the hammer is thimble shaped.

Several other Andean species, such as A. pachacuti Stark & Sivec, 1998 have similar aedeagal shape and features but none have the combination of a slightly offset apex, a Y-shaped keel and the low bubble-like hammer found in A. tucuman .
