Three new species from Southeast Asia of Euidothrips Ananthakrishnan (Thysanoptera, Thripidae, Panchaetothripinae) Author Masumoto, Masami Author Okajima, Shûji text Zootaxa 2010 2728 61 68 journal article 46905 10.5281/zenodo.200097 a85affc1-6ef5-4d85-bac7-8888d7276a16 1175-5326 200097 Genus Euidothrips Ananthakrishnan Euidothrips Ananthakrishnan, 1967 : 118 ; Wilson, 1975 : 115 . Type species: E. apsarus Ananthakrishnan , by original designation and monotypy. Diagnosis. Head ( Fig. 2 A) strongly reticulate, with raised reticulation between compound eyes, cheeks slightly rounded, constricted just behind compound eyes and at base; mouth-cone slightly pointed at apex, with 2- segmented maxillary palpi. Antennae ( Fig. 2 B, C) 8-segmented, segments III to VI weakly annulated but without microtrichia, III flared at base and narrowed near base, and more or less asymmetric, III and IV each with a Ushaped sensorium much elongate beneath the next segment. Pronotum ( Fig. 2 A) reticulate, without major setae. Mesonotum ( Fig. 4 D) with median longitudinal division incomplete. Metascutum ( Fig. 4 D) with median raised large triangular area reticulate; median pair of setae behind middle. Fore wing narrowed in distal two-thirds, veinal setae minute, microtrichia scattered and rough. Tarsi 1- or 2-segmented. Abdominal tergites ( Fig. 2 E, D) at least lateral to median setae with posteromarginal craspedum, median pair of setae closer to each other than their length; distinctly reticulate except submedian area on tergites I to V (or VII); tergite IX with pair of fimbriate S1 setae, each arising from a tubercle; tergite X with median longitudinal slit complete; sternites ( Fig. 2 F) reticulate, sternites II to VII with two to four (or five) pairs of posteromarginal setae, with or without discal setae. Ovipositor developed. Comments. Mound et al. (2001) indicated relationships among 31 genera of the Panchaetothripinae based on cladistic analysis using morphological characters, although the relationships were weakly supported. This analysis indicated that Euidothrips was sister to Moundothrips + Phibalothrips and this small clade was sister-group to Parthenothrips + Arachisothrips within a large clade including Heliothrips , Retithrips , Australothrips and Rhipipholothrips . Euidothrips is most similar to Phibalothrips , but in the latter genus the body is more slender and antennal segments III and IV have simple sensoria, also the fore wing has no anteromarginal fringes.
