Konothrips Bhatti 

Konothrips Bhatti 1990: 196  . Type species: Chirothrips tuttlei  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. 46View FIGURES 43 – 51). Mesonotum ( Fig 48View 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. 49View 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. 42View FIGURES 31 – 42, 50View 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 B 1 –B 2 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. 42View 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. 50View FIGURES 43 – 51), and the submarginal, sternal sculpturing is more longitudinally oriented ( Fig. 51View 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  .

Body brown, head darker brown than thorax or abdomen pale brown with anterior part and terminal segments darker brown; tarsi yellow, tibiae and femora brown with apical or proximal parts yellow, or fore tibiae mostly yellowish brown, femora and mid- and hind tibiae brown dorsally, yellow ventrally.

Prosternum ( Fig. 47View 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. 48View 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. 47View FIGURES 43 – 51). Metanotum ( Fig. 49View FIGURES 43 – 51): Sculpture lines longitudinally oriented except medially in arched pattern; median setae conical, as large as submedian setae on mesonotum, in anterior 1 / 4 of notum, lateral setae bristle-like; pair of companiform sensilla present.

Type material. Holotype female ( USNM); Texas, Coma 1 Co., Guadalupe River State Park, sweeping, 24 -IX- 88, G. Zolnerowich. Paratype females: 1, Texas, Lubbock Co., Slaton, onion field, 21 -VII- 86, R. Sites; 3, Texas, Bandara Co., Lost Mapels [sic, = Maples] State Park, 21 -VII- 88, G. Zolnerowich. Paratypes deposited in TESB and USNM.

Distribution. United States (Texas).

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.
