Revision of Bryobiella Tuttle & Baker (Acari, Tetranychidae), with ontogenetic development and redescription of B. desertorum. Zootaxa. 4540(1):93-131. Interpretive Summary: Spider mites are important agricultural pest on crops, ornamentals and fruit trees. Their damage cost many millions of dollars annually world wide. This article redescribe a not well known species of a spider mite and discuss its biology. This study will be important to plant protection officers, extension workers, Agriculture scientists, entomologists and plant growers. Technical Abstract: The genus Bryobiella Tuttle & Baker is redescribed and diagnosed. The type species B. desertorum is redescribed based on larvae, protonymphs, deutonymphs and adults including the paratype male. The ontogenetic developments of leg chaetotaxy is also discussed. The unique pattern of leg chaetotaxy of Bryobiella males among Tetranychidae is the addition of solenidia on femur and genu of leg I, femur, genu and tibia of leg II. Female variations of length of dorsal setae, pattern of striae between h2, number of setae tarsi I and II are discussed.The number of setae of trochanter III, relative length of palptibial claw to palptarsus in both females and males from different host plants are examined. A key to species of Bryobiella based on females is given. |
