Ceranisus loomansi S. Triapitsyn & Headrick, 1995

Ceranisus loomansi Triapitsyn & Headrick, 1995: 237 , 238, 246. (Type locality: Oak Creek Canyon near Flagstaff, Arizona, USA)

Ceranisus loomansi Triapitsyn & Headrick : Triapitsyn & Morse 2005: 76, 77, 83.

Diagnosis: Male and female: see Triapitsyn and Headrick (1995). This species is most similar to the Palaearctic species C. pacuvius and C. antalyacus and also to the Neotropical C. nigrifemora . C. loomansi can be most easily distinguished from C. pacuvius by the shape of the antennal scape in individuals of both sexes. The female scape is relatively shorter in C. pacuvius (length/width ratio 4–5:1) and longer in C. loomansi (length/width ratio about 7:1). Length/width ratio of the scape in male C. pacuvius is considerably less (1.4–1.7:1) than in C. loomansi (about 2.1:1). Female of C. loomansi also differs from that of C. nigrifemora in body colouration by being more or less uniformly black or dark brown; parts of antennae and legs as well as base of gaster are yellow to light brown in female of C. nigrifemora .

Material examined. Holotype female in USNM and paratypes in UCRC ( Triapitsyn & Headrick 1995).

Distribution: Canada (Triapitsyn & Morse 2005) and USA.

Hosts: Found in association with Scirtothrips citri (Moulton) ( Triapitsyn & Morse 1999) .

Ceranisus sp. 1

(Not included in the key)

Figs 57, 58 Diagnosis: Female. Unknown.

Male. Body dark brown to black, appendages slightly lighter. Antenna ( Fig. 57 ) with a slender scape and a rather compact flagellum. Disc of forewing hyaline. Genitalia ( Fig. 58 ) typical for the pacuvius species group but unusually large.

In habitus, this male resembles female of C. femoratus , for which no male is known, so one could only guess about their possible conspecificity. The antennal scape in this male is not swollen.

Material examined: JAPAN: Fukuoka Pref. (Kyushu Island): Mt Tachibanayama , 12.viii.1980, C.M. Yoshimoto, 1ơ [ CNCI] .

Hosts: Unknown.
