Amegilla teneriffensis (Cockerell, 1930) Kratochwil & Paxton & Aguiar & Husemann, 2025

Amegilla teneriffensis versus A. quadrifasciata

Amegilla teneriffensis is markedly larger in the following variables from A. quadrifasciata in females: body length (BL; p <0.0001), wing length (WL; p <0.0001), tegulae-scutum width (TSCW; p <0.0001), scutum-scutellum length (SCL; p <0.0001), metasoma width (MTW; p <0.0001), and metasoma length (MTL; p = 0.00082). In males, A. teneriffensis is markedly larger in metasoma width (MTW; p = 0.00039), and tegulae-scutum width (TSCW; p = 0.00097), and slightly larger in metasoma length (MTL; p = 0.026) and wing length (WL; p = 0.042), but not different in body length (BL) and scutum-scutellum length (SCL).

The scatterplots between the first shape PC and the isosize axis are separated in females and males ( Figure 4 View FIGURE 4 ). The PCA ratio spectrum separating the two species is characterised in females by the ratio of eye length/interocular upper distance to head length/ocelloocular distance (EL/IDU: HL/OOD), and in males by the ratio of wing length/ metasoma length to eye length/tegulae-scutum width (WL/MTL: EL/TSCW). The variables submarginal cell 2, length a (CU2a) and length of flagellomere 2 (FL2) are responsible for the differentiation of shape PC 1 in females of the two species, and the variables length of flagellomere 2 (FL2) and metasoma length (MTL) in males.
