“…La terminología general para los caracteres morfológicos siguió a Eickwort (1969a), excepto que lúnula es usado para referirse a la parte semicircular de la base dorsal del propodeo, denominada en algunos casos como área basal del propodeo o metapostnoto (Celis, Cure, & Aguilar-Benavides, 2014), plica para referirse a la marcación de la lúnula con fuertes surcos ( Fig. 4; P, Ver anexo digital), orla para la membrana traslúcida sobresaliendo del grá-dulo en TI y TII ( Fig.…”

Phylogeny and taxonomic classification to subgeneric level of Augochloropsis (Hymenoptera: Halictidae). Augochloropsis Cockerell, 1897b is a highly diverse group in the Neotropics and commonly collected in wildlife surveys. These bees remain mostly unidentified in collections because of the lack of taxonomic keys and the incomplete original descriptions, which prevent sorting specimens even at the subgeneric level. The aim of this study was to perform the phylogeny and the taxonomic revision of the genus Augochloropsis to subgeneric level, based on a detailed examination of 56 morphological characters of 2 433 specimens. Four subgenera are recognized and described in detail: (Augochloropsis s.str. (Cockerell, 1897b) (Paraugochloropsis Schrottky, 1906 ((Glyptochlora Moure, 1958) (Glyptobasia (Moure, 1941)))). Photographs of external morphological characters, illustrations of the male genital capsule and the metasomal sterna SIII-SVIII are provided, as well as a taxonomic key to subgenera and distribution maps.

“…Therefore, the cells size of C. alexandrei seems to be an intermediate range between these two species. The differences in the cells' measurements may be due to C. alexandrei is comparatively smaller (♀: 7.8-8.4 mm) (Celis et al, 2014) than A. virescens (♀: 11 mm) (Abrams & Eickwort, 1980), but Pap. Avulsos Zool., 2023;v.63: e202363002 11/16 larger than C. eberhardorum (♀: 4.5-5.5 mm) (Michener, 1979).…”

“…Some species build their nests with lateral burrows each leading to a single horizontal cell, while other species organize the nests into a cluster of more or less horizontal cells in a cavity, similar to the nests of some Augochlorini (Claude-Joseph, 1926;Michener, 2007). Although we know some aspects of the natural history of Caenohalictus, few studies (Nates-Parra et al, 2006;Michener et al, 1978) have focused on studying more details of the nesting behavior, social structure, and nest architecture of the Andean species belonging to this genus, as is the case of Caenohalictus alexandrei that was recently described by Celis et al (2014) from the Savanna of Bogota Plateau in the Eastern Andes of Colombia.…”

Behavior and nest architecture of the bee Caenohalictus alexandrei (Hymenoptera, Halictinae)

In Colombia, few studies have focused on nest architecture, behavior or sociality of wild bees. This study provides basic information on the nests of Caenohalictus alexandrei and presents behavioral observations outside the nests, derived from direct field observation of 40 nests and 39 male sleeping cavities in two localities of the Savanna of Bogota, Colombia. We recognized four different behavioral activities carried out by adult females: foraging, guarding, opening and closing of the entrance of the nest, with foraging being the most frequent of them. The observed activities were carried out more frequently from 9:00 h to 13:00 h. Males were observed performing two behavioral activities in the sleeping cavities: staying at the cavity entrance and cavity departure. A third male activity, corporal grooming, was carried out outside the sleeping cavity. Our field observations indicate that more than one adult female was active simultaneously performing the different tasks within a single nest. The nests presented different levels of complexity in their architecture, depending on the age of the nest and number of adult females in them. Descriptions of the nesting sites and behavioral activities as well as illustrations of the nest architecture are provided.

A new species of the paracolletine genus Lonchopria Vachal, Lonchopria (Biglossa) comforti Gonzalez & Engel, new species, from high elevations in the Central Andes of Colombia is described and figured. A preliminary key to the species of the Lonchopria subgenus Biglossa Friese is presented. Recent records of bees occurring at elevations above 2500 m in Colombia and other Andean countries are also summarized.
