Euseius vivax (Chant & Baker) View in CoL

( Figs 24–28 View FIGURES 24 – 28 )

Amblyseius vivax Chant & Baker, 1965: 23 .

Euseius vivax View in CoL .—McMurtry et al., 1985: 113; Moraes et al., 2004: 69, Demite et al., 2015.

Specimens examined. 20 specimens from the type locality: Estación Experimental Agrícola Fabio Baudrit Moreno, Universidad de Costa Rica on Ricinus View in CoL communis in November, 2012.

The characteristics of the females collected in this study are similar to those observed in the holotype, except for their longer Z5 and the shorter s4. A comparison of the characteristics of the holotypes of this species and of E. fructicolus View in CoL , as well as of specimens collected in this study in the respective type localities, led to a different conclusion from that of Denmark et al. (1999); thus, E. fructicolus View in CoL and E. vivax View in CoL should not be considered synonyms. The main differences between them seem to refer to the pattern of ornamentation of the dorsal shield (smooth in E. fructicolus View in CoL and lightly reticulated in the opisthonotal region in E. vivax View in CoL ) and the shape of the tips of leg IV macrosetae (blunt in E. fructicolus View in CoL and sharp in E. vivax View in CoL ). In the original description of E. vivax View in CoL , the authors mentioned that while the holotype (from Costa Rica) had sharply pointed macrosetae, most specimens from Nicaragua had either swollen tips or were intermediate. All 25 specimens collected in this study in Costa Rica as well as all specimens of a colony maintained in our laboratory had the sharply pointed leg IV macrosetae. Apparently, the specimens with swollen tipped macrosetae reported by Chant & Baker (1965) referred to another species.
