Haplothrips ganglbaueri Schmutz, 1913, p. 1034 .

This species is apparently widespread across the Oriental region, from Iran to Japan. However, it is possible that more than one biological entity is involved across this range, because females identified as this species from Iran have no fore tarsal tooth ( Figure 5 ), whereas females from Japan and Timor that have been examined have a small but distinct fore tarsal tooth, although otherwise are very similar in structure. Adults have been taken in various flowers, but the species seems to be primarily associated with Poaceae . In Iran, the species has been reported from Khuzestan Province ( Cheraghian and Hojat 1998), Fars Province ( Minaei and Alichi 2001) and Tehran Province ( Pirafkan et al. 2007). The species was reported from Iran by Mortazawiha (1995), but with no Province or locality information.

Diagnosis

Body brown, fore tibiae yellow at apex, mid and hind tibiae dark brown with extreme apices pale, all tarsi yellowish; antennal segments III–IV pale yellow; major body setae including sub-basal wing setae pale, but anal setae shaded. Head with mouth cone short, broadly rounded (cf. Figures 2, 4, 7 ), maxillary bridge wide and slender, about 0.6 times as broad as head; postocular setae capitate, much shorter than eyes, antennal segment III with one sensorium (cf. Figure 28 ). Major body setae capitate; fore tarsi without ( Figure 5 ) or with very small tooth. Pronotum with five pairs of major setae; mesopresternum boat shaped (cf. Figures 11–12 ). Forewing with five to nine duplicated cilia (cf. Figure 18 ); sub-basal setae S1, S2 short, capitate, S3 blunt, at least twice as long as S1 and S2. Pelta triangular (cf. Figure 16 ); tergite IX setae S1 and S2 pointed, shorter than tube; S1 on tergites I–VI capitate, on VII and VIII variable, capitate, broadly blunt, blunt or pointed; tergites VII and VIII with campaniform sensilla and micro-setae as in H. aculeatus ( Figure 32 ). Male with pseudovirga slender, bluntly triangular at tip, and with slight constriction before apex ( Figure 42 ).

Haplothrips globiceps Bagnall

Haplothrips globiceps Bagnall, 1934, p. 496 .

Haplothrips inoptatus Priesner, 1954, p. 56 . syn. n.

Described by Bagnall from Turkey on a specimen collected from Vitis vinifera, Priesner described H. inoptatus from Iran on one female taken on the leaves of Salix at Shiraz. He distinguished his new species as follows: middle and hind tibiae abruptly blackish-brown in more than basal third (in contrast he stated: ‘‘ globiceps (Bagn.) has middle and hind tibiae dark only at extreme bases’’); antennal segment VIII pale grey ( H. globiceps with VII and VIII ‘‘darker’’) ( Priesner 1954, p. 57). However, the colour of the mid and hind tibiae is variable in the series of eight specimens of H. globiceps from Turkey listed below, with the basal third to half dark. Some specimens from blackberry leaves in Iran, Karaj, have the apical antennal segments similar to those of the Turkish specimens, but others fit Priesner’s description of H. inoptatus . A few specimens from this series were compared with the holotype by Dr R. zur Strassen who concluded that they did not show any considerable difference. In view of the variation in the colour of the available specimens, H. inoptatus is here considered a synonym of H. globiceps . H. globiceps was reported from Iran by Mortazawiha (1995), but without any locality data. Also scarcely distinguishable on current evidence is H. rabinovitchi .

Diagnosis

Blackish brown; antennal segment I and base of II dark, VII and VIII usually pale grey, VI sometimes a little grey, other segments yellow; fore tibiae yellow, brown at extreme base and margins; the colour of mid and hind tibiae variable but usually with basal 0.3 to 0.6 dark ( Figure 10 ), all tarsi pale yellow; major body setae as well as basal wing setae and anal setae dark brown; postocular setae dark, finely pointed, about half as long as eye ( Figure 4 ), with pale tip. Head with mouth cone short; maxillary stylets retracted to eyes, 0.5–0.6 of head width apart ( Figure 4 ); antennal segment III with one sensorium ( Figure 28 ). Fore tarsal tooth apparently absent ( Figure 4 ). Pronotum with four pairs of major setae, midlateral setae usually finely pointed, remainder blunt; anteromarginal setae finely pointed, usually as long as discal setae but rarely as long as anteroangulars. Forewing sub-basal setae S1 and S2 variable at apex, finely pointed, weakly blunt or blunt, S3 finely pointed. Tergites II– VIII with setae S1 finely pointed or blunt; tergite IX setae S1, S2 and S3 pointed. Tube short, as long as or less than twice basal width (cf. Figure 31 ). Male similar to female but smaller and rarely with a minute fore tarsal tooth, aedeagus apex like a pointed spoon ( Figure 36 ).
