Konothrips Bhatti View in CoL

Konothrips Bhatti 1990: 196 View in CoL . Type species: Chirothrips tuttlei View in CoL zur Strassen by original designation.

Antennal segment I enlarged, more than 2.5 times as wide as base of segment II; segment II prolonged laterally, resembles inverted shoe, a well defined gland protrudes apically over sense cone on apex of the sclerotized part of process. Head with 40 plus short, stout setae anterior of fore ocellus. Pronotum subtrapezoidal, with numerous, short conical setae; without posteroangular setae or two pairs slightly larger than discal setae. Femur truncate apically, distal 1/3 sculptured with longitudinal, ridged lines or reticles ( Fig. 46 View FIGURES 43 – 51 ). Mesonotum ( Fig 48 View FIGURES 43 – 51 ) with 4–6 conical or spine-like, discal setae in median area far anterior to posterior margin, median pair of posterior setae absent, setae larger than those on pronotum; mesosternal furca invaginations separated by less than 2/5 to about width of metathoracic coxae. Metanotum ( Fig. 49 View FIGURES 43 – 51 ) with median pair of conical setae. Fore wings with 1 to few costal setae. Abdominal tergites with submarginal sculpture oriented longitudinally or diagonally ( Figs. 42 View FIGURES 31 – 42 , 50 View FIGURES 43 – 51 ), medially reticulated or transversely striate; 5 pairs of dorsal conical or spine-like setae, those on posterior tergites more elongate; posteromarginal flange narrow, about as wide as length of dorsal setae. Abdominal sternite with submarginal sculpture oriented longitudinally or diagonally; sternal discal setae absent; ovipositor short, 110–136 µm long. Male brachypterous. Smaller than female. Abdominal tergite IX with short B1–B2 setae; sternites III–VII each with glandular areas.

Comments. According to Bhatti (1990) Konothrips is distinguished by the sculpture on abdominal terga and sterna oriented longitudinally ( Fig. 42 View FIGURES 31 – 42 ); costa of fore wing without series of setae, having only a single seta; and ovipositor smooth, lacking teeth. Konothrips colei , new species, is intermediate in these structures between tuttlei , the type species of genus, and members of Arorathrips . In K. colei the abdominal tergal sculpturing is diagonally oriented on submargin and transverse or reticulated medially ( Fig. 50 View FIGURES 43 – 51 ), and the submarginal, sternal sculpturing is more longitudinally oriented ( Fig. 51 View FIGURES 43 – 51 ), the ovipositor is reduced but with sparse teeth, and the fore wing has sparse costal setae. The differences between Konothrips and Arorathrips are discussed in the comments for Arorathrips . The concept of Konothrips is revised here to accomodate K. colei .

Prosternum ( Fig. 47 View FIGURES 43 – 51 ) with basantra partially weakly sclerotized in posteromedial part, without setae, with finely granulose sculpture; prospinasternum a narrow unsclerotized band, spina inserted into mesosternum. Mesonotum ( Fig. 48 View FIGURES 43 – 51 ): Reticulated; anteromedian campaniform sensilla far apart; median posterior setae positioned near submedian setae, both setae far anterior of posterior margin, conical, larger than other setae on notum and pronotum; often with another pair of smaller, spine-like discal setae. Mesofurca with invaginations separated by 20–24 µm, 3/10 to 2/5 width of mesothoracic coxae ( Fig. 47 View FIGURES 43 – 51 ).

Etymology. Named after Charles L. Cole, retired thysanopterist formerly with the Texas Extension Service, Bryan, who provided the type material.

Comments. The specimens are mounted in Hoyer's medium and are rather flattened and distended. Thus the body and head measurements may not agree with those of properly mounted specimens. Also, the description of the coloration may differ from differently treated specimens.
