Morphological phylogeny and review of the generic classification of Colletinae (Hymenoptera: Colletidae) Author Ferrari, Rafael R Author Packer, Laurence text Zoological Journal of the Linnean Society 2021 2021-09-01 193 1 199 216 https://academic.oup.com/zoolinnean/article/193/1/199/5999476 journal article 10.1093/zoolinnean/zlaa128 0024-4082 10114860 HEMICOTELLES TORO & CABEZAS, 1977 ( FIG. 1A, B ) Type species: Lonchopria ruizii Herbst, 1923 . Diagnosis: Females of Hemicotelles can be easily differentiated from those of the other genera of Colletinae by T6 with a posteromedial longitudinal ridge (this study; Supporting Information, Fig. S11B) [T6 with a posteromedial protrusion that can be either weak and rounded (Supporting Information, Fig. S11C) or strong and subtriangular (Supporting Information, Fig. S11D) in Xanthocotelles , and T6 with no modification (Supporting Information, Fig. S9A–C) in Colletes and Mourecotelles ]. Males of Hemicotelles are diagnosed through the following combination of characteristics: apical mandibular tooth much longer than preapical tooth (this study; Supporting Information, Fig. S15A), legs dark-brown to black (modified from: Toro & Cabezas, 1978 ; see also Fig. 1A, B ) and horizontal surface of T1 much shorter than T2 (modified from: Michener, 1989 ; see also Supporting Information, Fig. S12C) [apical tooth only slightly longer than preapical one (Supporting Information, Fig. S15B) in Mourecotelles , legs pale-yellow to darkorange ( Fig. 1E, F ) in Xanthocotelles and horizontal surface of T1 subequal in length to T2 (Supporting Information, Fig. S12D) in Colletes ]. Hemicotelles can be further distinguished from Colletes by forewing with a straight second recurrent vein in both sexes (modified from: Toro & Cabezas, 1977 ; see also Fig. 3B ) [forewing with second recurrent vein either sigmoidal ( Fig. 3D ) or slightly arcuate outwardly ( Fig. 3C ) in Colletes ]; and from both Mourecotelles and Xanthocotelles by subhorizontal and vertical surfaces of the metapostnotum separated from each other by a transverse carina, albeit broadly interrupted medially in both sexes (modified from: Michener, 1989 ; see also Fig. 4D ) [metapostnotum without transverse carina ( Fig. 4C ) in Mourecotelles and Xanthocotelles ]. Additional species: Hemicotelles magallanes Toro & Cabezas, 1977 . Comments: Hemicotelles is the least diverse genus of Colletinae with only two described species – H. magallanes (southern Chile and Argentina ) and H. ruizii (central Chile ).
