Abstract
- Organothrips Hood Organothrips Hood, 1940: 423. Graminothrips Zhang & Tong, 1992: 82. Syn.n. One female and One male Of Graminothrips cyperi, the type species Of that genus, have been cOmpared with bOth sexes Of Organothrips indicus, a clOse relative Of O. bianchi, the type species Of that genus. These twO species share the fOllOwing unusual character states: head prOjecting in frOnt Of eyes; Ocellar setae I absent; maxillary palps 2-segmented; antennal segments withOut micrOtrichia, III and IV with simple sense cOnes, segment I with paired dOrsO-apical setae; prOsternal basantra with twO setae; fOre tibia inner apex with expanded fimbriate seta; tarsi 1- segmented; tergite pOsteriOr margins laterally with rOw Of micrOtrichia; sternite II with three pairs Of marginal setae; male sternites with multiple small pOre plates. MOreOver, there are nO significant character states by which cyperi and indicus cOuld be cOnsidered members Of different genera. As a result, Graminothrips is here cOnsidered a synOnym Of Organothrips. In this genus, the twO mOst well-knOwn species, bianchi and indicus, are clOsely similar in structure (MOund 2000). They are bOth assOciated with the leaves Of aquatic plants, Often living actually belOw the water surface in the mucilage On stems Of Colocasia, Eichornia and Typha (Bhatti et al. 1998; MOund 2000). In cOntrast, the third species placed in the genus, O. wrighti, was taken frOm grasses at a damp site. Similarly, G. cyperi and G. longisetosus were described frOm specimens taken frOm nOn-aquatic plants, the first frOm Cyperus and the secOnd frOm grass. In cOntrast tO the twO semi-aquatic species, O. wrighti has the first antennal segment reduced in size and lacking paired dOrsO-apical setae, and mOreOver this species has Only twO pairs Of marginal setae On the secOnd abdOminal sternite. Of the twO specimens Of cyperi that have been studied, paired dOrsO-apical setae are clearly present On the first antennal segment Of the male, but On the female these setae are minute and cOuld be seen clearly Only by using a X100 Objective lens. The relatiOnships Of G. longisetosus are mOre difficult tO assess. Despite sharing several character states with the Other species Of Organothrips it differs in the fOllOwing: Ocellar setae I present; prOsternal basantra withOut any setae; tarsi 2-segmented. MOreOver, accOrding tO PrOf. TOng XiaOLi (in litt. ii.2018), paired dOrsO-apical setae are either present Or absent amOng specimens Of this species that have becOme available tO him subsequent tO the Original descriptiOn. The fOllOwing new combinations are required as a result Of the abOve generic synOnymy: Organothips cyperi (Zhang & TOng); Organothrips longisetosus (Zhang & TOng).<br />Published as part of Zhang, Shimeng, Wang, Zhaohong, Li, Yajin & Mound, Laurence, 2018, One new species, two generic synonyms and eight new records of Thripidae from China (Thysanoptera), pp. 370-378 in Zootaxa 4418 (4) on page 375, DOI: 10.11646/zootaxa.4418.4.3, http://zenodo.org/record/1244922<br />{"references":["Hood, J.
