INTRODUCTION described. Subsequently, we already indicated that Late Cretaceous , and especially true bugs, there were no sufficient reasons to place the latter fam or heteropterans, remain poorly knows: the number of ily in Tingoidea, and suggested that it is one of the both described species and studied localities remains coleopteroid forms of the cimicoid family Microphys many times smaller than that of Early Cretaceous idae (Golub and Popov, 2008). From the same Creta ones. The Turonian locality KzylDzhar in the north ceous amber of France, another member of Cantaca ern part of the Kara Tau Range (Southwestern Kaza derinae was described: Ambarcader eugenei (Perrichot khstan), where a small number of true bugs have been et al., 2006). From the lower layers of the Upper Cre found, is no exception. In addition to the peculiar taceous of the United States (Turonian amber of New member of pleoid water heteropterans of the Creta Jersey), two monotypic genera of tingoid Vianaididae ceous family Mesotrephidae (Mesotrephes striata were described: Vianagramma goldmani Golub et Popov) described earlier (Popov, 1971), early terres Popov, 2000 and Vianathauma pericarti Golub et trial true bugs of the families (three genera Popov, 2003 (Golub and Popov, 2003). However, the including three species), s.l. (two genera placement of the latter species in Vianaididae was not including two species), ?Idiostolidae, ?Velocipedidae, accepted subsequently by the authors who were the and , have been found at this locality, as well as first to study a fully winged form of a recent member of the member of Tingidae described in this study. It this family (Schuh, Cassis, and Guilbert, 2006), and should be noted that this Cretaceous locality, formed therefore we consider this question open. after the midCretaceous shift in faunas (Roh dendorf and Zherikhin, 1974), which coincided with The new species of Tingidae described here is char the last of the major floristic shifts, the Mesophytic– acterized by the following features: small cell structure Cenophytic transition (Albian–Cenomanian), has a of hemelytra; corium divided by protruding longitudi pecular faunistic composition of heteropterans. nal veins into costal, subcostal, discoidal, and sutural To date, three species of Tingidae have been known fields; posterior margin of pronotum straight, not reliably from the Early Cretaceous: Golmonia pater overlaying scutellum, thus entirely visible in dorsal Popov, 1989, Sinaldocader drakei Popov, 1989, and view; and presence of protruding crossveins crossing S. ponomarenkoi Golub et Popov, 2008. In addition, in subcostal field. These features allow placing the new the superfamily Tingoidea, the peculiar monotypic species in the tribe Phatnomatini (Tingidae, Cantaca family Ignotingidae from extreme Early Cretaceous derinae). The division of the discoidal field with (?Berriasian; Zhang et al., 2005) and the family oblique veins into three large cells (basal, medial, and Ebboidae from the Cretaceous amber of France radial) shows that the new species belongs to the genus (Albian–Cenomanian; Perrichot et al, 2006) were Sinaldocader Popov.
