Andinopanurgus, Gonzalez & Engel, 2011

Packer, Laurence, 2021, Two new species of Andinopanurgus (Hymenoptera: Andrenidae: Panurginae), with a description of the female of A. amyae, Journal of Melittology 2021 (101), pp. 1-19 : 13-15

Modifications for Identification Keys for Andinopanurgus

Insertion of the following couplets at the beginning of Gonzalez et al.’s (2019) key for Andinopanurgus males will enable the newly described species to be identified:

A. S4 with highly modified branched setae, some of which are rake or trident-like ( Figs. 4–5 , 13–14 ) ........................................................................................................ B

—. S4 without highly modified setae, S5 sometimes with unusually structured setae ............................................... couplet 1 (page 215) of Gonzalez et al. (2019)

B(A). Clypeus black, lacking apical transverse cream-colored band; S4 setae with from two to four branches ( Figs. 4–5 ) [ Argentina] ........... A. chirosimpson , n. sp.

—. Clypeus with apical transverse cream-colored band; S4 setae with from two to five branches ( Figs. 11–12 ) [ Peru] ............................................. A. lynnae , n. sp.

Insertion of the following couplet at the beginning of Gonzalez et al.’s (2019) key for Andinopanurgus females will enable identification of the female of A. amyae :

A. Hypostomal carina strongly sinuate, concave anteriorly, strongly convex posteriorly ( Fig. 18 ) ........................................................... A. amyae (Gonzalez & Engel)

—. Hypostomal carina linear ( Fig. 23 ) ............ couplet 1 of Gonzalez et al. (2019: 216).

For identification of the female of A. lynnae , the following modifications are required to Gonzalez et al.’s (2019) key:

4. Metatibial scopal hairs whitish ( Fig. 13 ) .............................................................. 4A

—. Metatibial scopal hairs brown-black ( Fig. 16 ) ........................................................... ....................................................................... couplet 5 in Gonzalez et al. (2019: 216)

4A. Metasomal terga with apical impressed areas translucent, area immediately anterior to apical impressed areas somewhat orange clearly differing from dark brown of discs of terga ( Gonzalez et al., 2019: figs. 1b-d); facial fovea ≈3.7× longer than wide; mesotibial spur ≈0.8× length of mesobasitarsus .............................. ........................................................................... A. vargasllosai Gonzalez & Alvarado

—. Metasomal terga with apical impressed areas red-brown, areas immediately anterior to apical impressed areas almost concolorous to discs of terga ( Fig. 13 ); facial fovea ≈5× longer than maximum width; mesotibial spur ≈0.95× as long as mesobasitarsus ( Fig. 15 ) .................................................................... A. lynnae , n. sp.
