Haplothrips kermanensis zur Strassen

Haplothrips kermanensis zur Strassen, 1975, p. 138.

Currently known only from Iran, this species is unique among Iranian Haplothripini in the presence of extra setae on the anterior half of the metanotum ( Figure 17 ), nonpedicellate antennal segment VII ( Figure 24 ), and the fore tarsal tooth developed even in females ( Figure 2 ). It appears to be host-specific to Haloxylon .

Diagnosis

Blackish brown; all tarsi, fore tibiae (except the base), distal apex of mid and hind tibiae and antennal segments III–VI yellow; major body setae as well as sub-basal wing setae pale; base of anal setae brown. Head with maxillary stylets about onethird of head width apart, retracted to postocular setae ( Figures 2–3 ); postocular setae blunt or weakly blunt, extending beyond posterior margin of eyes; antennal segment III with two sensoria ( Figure 27 ); segment VII not pedicellate ( Figure 24 ). Fore tarsal tooth present ( Figures 2–3 ), rarely small in female. Pronotum with five pairs of major setae, blunt except for pointed anteromarginals; midlaterals variable, sometimes as long as anteromarginals or smaller; mesopresternum divided into two lateral triangles (cf. Figure 13 ); metanotum with one pair of minor setae on anterior half ( Figure 17 ). Forewing sub-basal setae S1, S2 blunt, S3 weakly pointed. Pelta usually triangular (cf. Figure 16 ); tergite VII with two campaniform sensilla not close to each other, VII and VIII each with two to four micro-setae (cf. Figure 34 ). Tergite IX setae S1, S2 and S3 pointed, rarely weakly blunt; S1 on other tergites variable, blunt, finely pointed or pointed. Tube short (cf. Figure 31 ), at most twice as long as basal width.

Material examined

Haplothrips kurdjumovi Karny

Haplothrips kurdjumovi Karny, 1913, p. 8 .

This species was reported from Iran, Khorasan Province, by Alavi and Kamali (2003) on the basis of three females from Populus leaves. It is widespread from central Europe to central Asia ( Priesner 1964), and is also known from North America and New Zealand ( Mound and Walker 1986), as well as Japan ( Okajima 2006). In structure, it is very similar to the western European species H. subtilissimus , and both are known to be predatory on mites and Lepidoptera eggs. They were distinguished by Nakahara (1985), and according to the few specimens examined in this study they differ as follows:

(1) Sub-basal wing setae shaded in H. subtilissimus , but pale in H. kurdjumovi .

(2) Pronotal anteromarginal setae about as long as anteroangular setae in H. subtilissimus , but smaller than anteroangulars and only as long as discal setae in H. kurdjumovi .

(3) Pronotal anteromarginal setae of female blunt in H. subtilissimus , but finely acute in H. kurdjumovi .

(4) Females with a minute, subapical tooth on inner side of fore tarsus in H. kurdjumovi but this is absent in H. subtilissimus .

Diagnosis

Body brown; tarsi, apical half of fore tibiae, antennal segments III–V and basal half of VI yellow; all setae on head and pronotum, also setae on abdominal tergite IX, brown; sub-basal wing setae pale; forewings pale, dark at extreme base; fringe cilia dark. Head about as wide as long; postocular setae blunt; maxillary stylets retracted to postocular setae (cf. Figures 2–4, 7 ), about 0.3–0.5 of head width apart; antennal segment III with one sensorium (cf. Figure 28 ). Pronotum with five pairs of major setae, anteromarginal setae small, as long as discal setae or shorter than anteroangulars, finely acute; remaining setae broadly blunt; mesopresternum boat shaped (cf. Figures 11–12 ). Female with very small fore tarsal tooth. Forewing subbasal setae S1 and S2 blunt, S3 pointed. Tergite IX setae S1, S2 and S3 pointed; tube short (cf. Figure 31 ).

Material examined

New Zealand: Earnscleugh , 1 ♀ from apricot leaves, 14.x.1981, 1 ♀ from apricot fruits 25–31.x.1978; Alexandra, 1 ♀ from Apple leaves; the same place, 1 ♀ from lupin .
