Ceranisus russelli ( Crawford, 1911) View in CoL
Thripoctenus russelli Crawford, 1911: 233 View in CoL . (Type locality: Compton , California, USA)
Ceranisus russelli (Crawford) View in CoL : Peck 1963: 117; Loomans & van Lenteren 1995: 119–123, 196; Triapitsyn & Headrick 1995: 232, 233 (designation of the lectotype and paralectotypes, redescription), figs 7, 8 (p. 243) and 18, 19 (p. 247); Triapitsyn & Morse 2005: 71.
Diagnosis: Female. See Triapitsyn and Headrick (1995). Female clava usually 3-segmented (at least on one of the antennae), but sometimes subdivision of the distal claval segment is difficult to see even in slide-mounted specimens.
Male. Unknown.
Type material examined: Lectotype female and 28 paralectotype females in USNM, listed by Triapitsyn & Headrick (1995), as well as 19 additional paralectotype females listed by Triapitsyn & Morse (2005).
Other material examined: 4 females on a slide (mounting media completely black), labelled:1. “ Thripoctenus russelli Crawf. bred fr. Heliothrips fasciatus Compton, Cal. U.S.A., IX /1911 R. S. BAGNALL “ [ BMNH]. These specimens apparently came from the same source as the type series of C. russelli (all collected during 1911 in Compton, California, USA, by H.M. Russell or/and J.E. Graf) but are not designated as paralectotypes because they lack an indication that they were sent to USNM under the number 618°, as the cotypes of this species had been ( Crawford 1911) .
Distribution: Canada (Triapitsyn & Morse 2005) and USA.
Hosts: See Loomans and van Lenteren (1995).
Comments: Initial placement of this species in Ceranisus was tentative ( Triapitsyn & Headrick 1995) because its female has the following features characteristic of Thripobius : one pair of setae on the mesoscutal midlobe in the majority of specimens (two pairs in one of the paralectotypes), a 3-segmented clava (although only 2 segments are clearly visible in some specimens), and very long setae on the funicle segments (this is not a good generic character, however, even though it was used by Boucek (1976) in his key to separate Thripobius from Ceranisus ). All other important morphological features, including a straight malar sulcus, suggest that this species rather belongs in Ceranisus .
