Eutetranychus papayensis Iqbal & Ali, 2008 

Eutetranychus papayensis  Iqbal & Ali, 2008: 125−130.

Host and Distribution.

Female, from Carica papaya  L. ( Caricaceae  ), Abbottabad, Pakistan.

Eutetranychus papayensis  was described with coxae I−IV 2−2−2−2 (whereas they illustrate 2−2−1−1 setae) and three pairs of anal setae. Also, the empodium of this species were neither described nor illustrated. So, based on these characters together, E. papayensis  can neither be placed in Eutetranychus  nor even in other genera of the family Tetranychidae  .The first author has informed us that type specimens of this species have been lost. Therefore, E. papayensis  is considered as a species inquirenda.

After excluding those seven species which we suggest as synonyms and one species inquirenda, the genus Eutetranychus  includes 28 species (including the new species described herein) and is divided into two species groups based on the number of setae (one or two) on coxae II: the species group orientalis  has one seta on coxa II (12 species) and the species group banksi  has two setae on coxa II (16 species). The number of setae on coxae II has been considered as a solid morphometric character founded to be strongly constant in all specimens of each Eutetranychus  species ( Pritchard and Baker 1955, Baker and Pritchard 1960, Chaudhri et al. 1974, Meyer 1974, 1987, Khanjani et al. 2017).
