(COI: OP956139 View Materials ), Beijing , 15.VIII.2017, No. 45505-1-1, on Apiaceae , coll. H. Long.

Diagnosis.

Pronotum and abdominal tergites I-IV each with large and circular marginal tubercles, larger than spiracles (Fig. 29D, F View Figure 29 ); setae of legs very long, pointed, dense, and curved apexes (Fig. 29G, H View Figure 29 ), the setae on femora 0.57-0.78 × of widest width, the setae on tibiae 0.97-1.39 × of mid-width; cauda tongue-shaped, with 9-16 long and pointed setae (Fig. 29M View Figure 29 ) ( Takahashi 1961).

Comment.

After researching the holotype of Cavariella largispiracula Zhang, Chen, Zhong & Li, 1999, we found the species is in fact without large circular spiracles, which are in fact marginal tubercles and with normal reniform spiracles (Fig. 31A, C View Figure 31 ). In C. largispiracula , thoracic nota and abdominal tergites I-IV each with one pair of large marginal tubercles (Fig. 31C View Figure 31 ); abdominal tergites VIII with a slightly swollen supra-caudal process (Fig. 31D View Figure 31 ); cauda tongue-shaped (Fig. 31F View Figure 31 ); setae of legs very long and pointed ( Zhang et al. 1999). Therefore, Cavariella largispiracula Zhang, Chen, Zhong & Li, 1999 is considered as a junior synonym of Cavariella sapporoensis Takahashi, 1961.

The species resembles Cavariella heraclei Takahashi, 1961, but differs from it as follows: setae of legs long, pointed, dense, and curved apexes ( C. heraclei : setae of legs short, blunt, sparse); cephalic setae long and pointed, 1.31-2.74 × Ant. IIIBD ( C. heraclei : cephalic setae short and blunt, 0.50 × Ant. IIIBD); setae of Ant. III long and pointed, 0.86-1.24 × Ant. IIIBD ( C. heraclei : setae of Ant. III short, 0.50 × Ant. IIIBD) ( Takahashi 1961).

Biology.

The species is usually collected from Apiaceae and feeds on the undersides of leaves with ant attendance (Fig. 37B-D View Figure 37 ). In China, the apterous oviparous female of the species was found feeding on the leaves of Salix in October. So, the species may alternate host between Salix and Apiaceae .

Distribution.

China (Beijing, Gansu, Jilin), Japan.
