LITERATURE: Friese (1910: 649) : comparative note ( C . araucariae Friese, 1910 ); Friese (1912: 367) : key (female); Toro (1986: 123) : distribution (southern Chile ); Toro (1999: 26 , 30): key (female), note on type specimen (depository), distribution (Region XI, Chile ); Moure & Urban (2002: 15) : lectotype designation (as C . neuqueenensis ); Montalva & Ruz (2010: 22) : distribution (Regions IV–IX, Chile and Mendoza and Neuquén , Argentina ) (as C . neuqueenensis ); Ascher & Pickering (2018) : distribution (Region XI, Chile and Neuquén , Argentina ); Ferrari (2017: 126) : key (female). Figures 1–4. Female lectotype of Colletes neoqueenensis Friese. 1. Habitus, dorsal view. 2. Face, frontal view. 3. Habitus, lateral view. 4. Labels. Scale bars = 2mm. DIAGNOSIS: The female of C . neoqueenensis (the male remains unknown) can be diagnosed through the combination of the following features: clypeal mid-longitudinal area flat and not depressed; mesoscutum with pale-yellow and fuscous hairs intermixed; mesepisternum with imbricate interspaces; and metasomal terga black, covered with pale-yellow, dense tomentum. Colletes neoqueenensis is most similar to C . longiceps Friese, 1910 , but the clypeal mid-longitudinal area is densely punctate (I=0.5–1D) in the former [sparsely punctate (I=1.5–2D) in the later]. In addition, the paraocular area is covered with mixed pale-yellow black hairs in C . neoqueenensis (paraocular area with only pale-yellow hairs in C . longiceps ). Colletes neoqueenensis is also very similar to C . toroi Ferrari, 2017 , but they can be differentiated by mesoscutum with pale-yellow and fuscous hairs intermixed in the former (mesoscutum with only pale-yellow hairs in the later); and by mesepisternum with imbricate interspaces in C . neoqueenensis (interspaces smooth in C . toroi ).

T 1– T 4 covered with dense, appressed hairs; T 1 with erect, long (L=2.5–3× MOD ) hairs among appressed hairs; T 2– T 5 also with erect setae laterally, shortest (L=1–1.5× MOD ) on T 2, longest (L=2–2.5× MOD ) on T 4– T 5. Disc of T 5 with suberect, short (1–1.5× MOD ) setae; discal setae thick on T 6. S1 with erect, plumose, moderately long (L=1.5–2× MOD ) hairs.

Lectotype ( Figs. 1–4 ) designated by Moure & Urban (2002: 649) and deposited at the ZMB . RANGE : Argentina ( Mendoza, Neuquén ). Also listed for Chile ( Regions IV and XI ) , but see “Discussion”, below. COMMENTS: Colletes neoqueenensis is an uncommon species only known to me by its female lectotype , which is in very good condition. In the original description, Friese compared C . neoqueenensis with C . araucariae Friese, 1910 (= C . sulcatus Vachal, 1909 ), however, the former species is most similar to C . longiceps and C . toroi (see “Diagnosis”, above). From C . sulcatus , C . neoqueenensis can be easily differentiated by mesepisternum with imbricate interspaces (interspaces smooth in C . sulcatus ), and posterior hind tibial spur pectinate (spur ciliate in C . sulcatus ).
