Genu I 2­2/1­2/1­2, genu II 2­2/0­2/0­1, genu III 1­2/1­2/1­0, genu IV A 1­2/1­2/1­0.</p> <p>Etymology</p> <p>This species is named after the late Dr Wilbur R. Enns in recognition of his roles as teacher and advisor in the Department of Entomology, University Missouri­Columbia.</p> <p>Remarks</p> <p>This species closely resembles Euseius quetzali McMurtry et al., 1985, a species described from Guatemala and also reported from Mexico and California (Demite et al., 2019). Congdon</p> <p>&amp; McMurtry (1986) compared the morphology of populations from California and Guatemala identified as E. quetzali. They were very similar, except for the larger ratios j 1/ j 3 and z 4/ z 2,</p> <p>and shorter peritreme in the Californian population; these characteristics of the Californian population are comparable with those of the specimens collected in this study. Results of crossing experiments conducted by Congdon &amp; McMurtry (1986) led them to conclude that the</p> <p>Californian population belonged to the same species as populations they collected in Mexico and Guatemala. In the first part of that study, no offspring were obtained when crossing</p> <p>Californian E. quetzali and Mexican Euseius hibisci (Chant), indicating that they belonged to different species. However, the results obtained when crossing Californian populations of those species were not considerably different from the results obtained when crossing Californian and Guatemalan populations of E. quetzali. In both cases, females were never produced in the crossings. In the first case, males and females were produced only by E. hibisci females, while in the second case, males and females were produced by females from both areas. Hence, we consider that their decision about the identity of the species was based on the lack of sufficient evidence that they belonged to different species rather on the availability of evidence showing that they belonged to the same species. Phytoseiids are known to reproduce mainly by a process designated as pseudoarrhenotoky (Hoy, 2011), in which offspring are only produced after mating and fertilization of the eggs.</p> <p>According to our examination of paratypes of E. quetzali, from data provided in the original description of the species (McMurtry et al., 1985) and in the redescription by Congdon &amp;</p> <p>McMurtry (1986), this new species differs from E. quetzali by the ornamentation of the dorsal shield (smooth in the central area of the podonotal region of the dorsal shield E. in quetzali), and by the much shorter j 4– j 6, J 2, z 5, Z 1 and Z 4, which appear to be the shortest dorsal shield setae of the new species but also shorter than that of E. quetzali. In our examination of the paratype females, the peritreme extends only up to z 2, instead of up to j 3 as shown in the illustration of the original description.</p> <p>Euseius ennsi n. sp. is also similar to E. obispoensis Aponte &amp; McMurtry, 1997 especially for the strong reticulation of the dorsal shield. The latter differs for: having r 3 always and R 1</p> <p>occasionally on dorsal shield; most dorsal shield setae as long as to up to 20% longer except z 4</p> <p>and s 4, about 20% shorter; and ventrianal shield strongly reticulate in preanal region and light reticulation in anal region. The new species also resembles E. citri van der Merwe &amp; Ryke,</p> <p>1964 and E. citrifolius Denmark &amp; Muma, 1970 ; however, E. citri has calyx of spermatheca slightly bulged near atrium and flaring near vesicle, whereas E. citrifolius has dorsal shield only lightly reticulate and macroseta of basitarsus IV distinctly bent. As the latter species, E. relictus</p> <p>Chaudhri, Akbar &amp; Rasool differs from the new species by having macroseta of basitarsus IV</p> <p>(as well as macrosetae of genu and tibia IV) distally bent. Euseius vulgaris Liang &amp; Ke, 1983</p> <p>differs from the new species for having peritreme longer (reaching midway between insertions of j 3 and z 2, and ventrianal shield almost twice as wide at anus level than at level of Zv 2.</p> <p>This new species is also very closely related to E. vivax (Chant &amp; Baker) and E. fructicolus</p> <p>(Gonzalez &amp; Schuster) but differs from both in that the dorsal shield is completely reticulated and not smooth as in E. fructicolus and lightly reticulated as in E. vivax. They also differ from the new species in the shape of the tubelike calyx of the spermatheca, which is almost straight in the former two but bent or coiled in the new species. The macrosetae on leg IV of</p> <p>E. fructicolus are blunt distally but acute in the new species. Setae Z5 are serrated in the new species but smooth in both E. vivax and E. fructicolus. In the new species setae Z5 is about six times as long as j6 and J2 but about five times or less in E. vivax and E. fructicolus, respectively</p> <p>(Lopes et al., 2015).</p></div> 	https://treatment.plazi.org/id/9C5EF41FC84DFFC26E86C2B774E15C17	Public Domain	No known copyright restrictions apply.
