Extracted from: Gonzales, V.H. et al. 2013 Species status and new distribution records for Lithurgus huberi Ducke (Hymenoptera,
Megachilidae, Lithurginae). JHR 30: 13–18 (2013)
Females of L. huberi primarily differ from those of L. atratus by the facial prominence.
In L. huberi it is more strongly punctate and more depressed along the epistomal sulcus
than in L. atratus (cf. Figs 1, 3 vs. 2, 4). Likewise, males of L. huberi differ from those
of L. atratus in the inner glabrous surface of the metabasitarsus, which is broader and
more projected (cf. Figs 5 vs. 6). Although subtle, such morphological differences appear
to be consistent across the specimens examined. However, we have had access to
a limited number of individuals from a restricted set of localities and cannot rule out
that such differences represent mere geographic variations.
