Streothrips Bhatti

Streothrips Bhatti, 1971: 89 . Type species Streothrips arorai Bhatti

Although Bhatti erected this genus for a single species from central India, two further species have subsequently been described; alaris from Philippines ( Reyes 1994) and moundi from Malaysia ( Ng & Eow 2012). These species are similar to other Aeolothripidae in having 9-segmented antennae with linear sensoria on segments III and IV. They are also similar to Aeolothrips species in having the distal maxillary palp segment not subdivided, and in lacking discal setae on the sternites. Whereas Aeolothrips species have the metascutum more or less reticulate, Streothrips species have the meso- and metanotum bearing close striations. Members of this Oriental genus share this character state with species in the Neotropical genus Ambaeolothrips , but they have the pronotum smooth ( Mound et al. 2016) in contrast to the striate pronotum of Streothrips species. Perhaps more closely related is Aduncothrips from India, but the species in that genus have the sensoria on antennal segments III–IV unusually long and with internal markings, and the abdominal sternites have discal setae ( Ananthakrishnan 1963). One female of an unidentified species of Aduncothrips from Thailand has been studied, and sternites III–VII have between one and four pairs of discal setae placed anterolaterally close to the antecostal ridge.
