Remarks. P. rothneyi is easily confused with the closely allied species P. olivaceus, P. jokahamae and P. tenuispunctia. It is a polytypic species with a very interesting variable colour pattern. Van der Vecht (1968) treated them as 16 subspecies and two uncertain? subspecies A and B. Das & Gupta (1989) added one. Even though, these more than 17 colour forms still could not cover all the variation. Among them, seven “subspecies”, i.e. koreanus, tibetanus, gressitti, hainanensis, grahami,? subspecies A and B, are recorded from China. P. yayeyamae is possibly also distributed in Taiwan. The colour differences between grahami, hainanensis and gressitti, are very small and mainly related to the colour of the pronotum and the first metasomal tergite. The colour forms grahami and hainanensis overlap in Hainan and it is better to unite these colour forms. Even within f. grahami there are two colour patterns (mesoscutum with four stripes or two stripes) and are sympatric in China. The colour pattern of some specimens collected in Yunnan intergrades f. rothneyi and f. tibetanus having four reddish brown stripes on the mesoscutum but the first tergite mostly black (Fig. 19). However, one specimen collected in Yunnan (no. 20046541) has the head reddish yellow and the bands and stripes yellow with reddish brown tinge, what fits f. sikkimensis well. In addition, the two uncertain A and B forms show a more or less continuous variation series. Similar situation occurs between the specimens from northeastern China, f. iwatai (area on basal band and waved line on the second metasomal tergite often somewhat reddish) and f. koreanus (the first metasomal tergite black with a narrow apical band). It is interesting that the colour pattern of f. iwatai is very similar to that of f. grahami so that the latter can be considered transitional. Van der Vecht (1968) mentioned that the colour of the body ranges from paler or dark yellow through various shades of brownish red to black. He roughly divided the specimens into three groups i.e. yellow and black, brownish-red and more or less transitional forms. Our observations showed that the Chinese colour forms of P. rothneyi can be defined only by colour patterns that intergrade in some degree. This leads us to synonymize all (as far seen from China) as colour forms of P. rothneyi. Since it is difficult and tedious to describe the colour patterns in words, we prefer to show its variation in a series photographs (Figs 19–21). Referring to van der Vecht (1968), we divide the examined Chinese specimens into three colour groups i.e. Southwest Plateau group (brownish-red to black, distributed in southeastern China, Yunnan and Tibet), Common yellow-black group (widely distributed in the mainland of China spreading southward to Hainan and Taiwan, including f. grahami, f. hainanensis, f. gressitti and f. yayeyamae) and Northeast group (colour pattern between f. iwatai and f. koreanus, generally with reddish brown blotches, the first metasomal tergite black, at most with a narrow apical band; distributed in Northeast China, Shandong (Weihai), Liaoning, Jilin). For convenience we use the available names as colour forms for arranging the specimens into different colour groups. We did not find a colour gap between the Common black yellow group (Fig. 21) and the Northeast group (Fig. 22).
