Bagnalliella Karny Bagnalliella Karny (1920:41). Type- species by original designation.— Cephalothrips yuccae Hinds. Head moderate in size and some- what broadened anteriorly, often with depressed lines or wrinkles behind eyes especially in brachypterous forms. Eyes normal. Ocelli present in all forms. Postocular setae usually pointed. Antennae eight segmented, each segment fairly small, none en- larged. Maxillary stylets retracted far into the head, placed fairly close to- gether. Maxillary bridge present, short. Mouth cone broadly rounded. Prothorax with only anterolateral, epimeral, and lateral posterior margin- al setae well developed, these setae usually blunt at their tips. Praepectus present. Epimeral sutures complete. Macropterous or brachypterous. Ma- cropterous forms with fore wing slight- ly narrowed at the middle or entire apical half narrowed, accessory fringe cilia present. Fore tarsi armed in both sexes. Pelta triangular (Fig. 214). Wing- holding setae slightly curved or slight- ly sigmoidal. Tube moderate-sized. Accessory setae on abdominal ster- nites minute. Males apparently with- out sternal glandular areas, and with lateral posterior setae on abdominal tergite IX Fig. 214.—Bagnalliella yuccae, pelta. This genus is similar to Haplotkrips. From Haplotkrips, Bagnalliella may be distinguished by the combination of the characteristics a) wrinkles be- hind eyes in the brachypterous form, b) reduction of both t
