Tenuipalpus kermanicus sp. nov. , a dult female. Right legs: leg I (29), leg II (30), leg III (31), leg IV (32) and pretarsus (33). Remarks. This new species belOngs tO the keiensis subgrOup Of the proteae grOup. Ιn additiOn tO the six species listed in Khanjani et al. (2013), the grOup alsO cOmprises: T. bassiae MOhanasundaram, 1988 , T. clematidos Wang, 1983 , T. ilocanus COrpuz-RarOs, 1978, T. isabelae Mesa et al. , 2006 , T. salicis Al-GbOOry, 1987 and T. tauricus ( MitrOfanOv & StrunkOva, 1978 ). Tenuipalpus clematidos and T. salicis are tentatively included here, as they appear tO have setae f2 but lack setae d3 ; it is necessary tO nOte that setae d3 are sOmetimes OverlOOked, if they are small, situated marginally, and Obscured by leg ΙΙΙ. The brOad, ObOvate tO OblanceOlate dOrsal setae Of T. kermanicus sp. nov. distinguish it frOm mOst species in the proteae grOup. Ιn this regard, the new species is mOst similar tO T. berkheyae . These twO species are easily separated by numerOus features such as the three-segmented palps (twO-segmented in T. berkheyae ), the lateral hysterOsOmal ridge (absent in T. berkheyae ), dOrsal pOsitiOn Of seta d On femur Ι (lateral in T. berkheyae ) and genual setal cOunt Of 3-3-1-0 (1-1-0-0 in T. berkheyae ). Etymology. This species is named after the prOvince Of Kerman .
