Notes on types.

Taicona aurata Bates. Bates (1873) didn’t state the number of specimens in the type series. We found a total of four specimens bearing Bates’ determination labels in the collection of MNHN and NHML. Two specimens from different collections were both determined and labeled as “type”. We herein designate the male in the collection of MNHN as lectotype ( Fig. 51 View Figures 49–54 ) for taxonomic purpose of fixing the name to unique name-bearing type.

Taicona perroti Jedlička. As indicated in the original description, the holotype of Taicona perroti Jedlička should be in MNHN. But we didn’t find it in MNHN or NMPC where the collection of Jedlička is deposited. We suspect that the holotype is probably still in MNHN, but has been misplaced.

Diagnosis.

Elytra metallic green or cupreous-green, disc with more or less distinct reddish patch in some specimens; metasternum and abdomen not darker than prosternum; front angles of pronotum with setae very fine and short (as in Fig. 151 View Figures 138–157 ); elytral 7th interval without setigerous pores; internal sac of aedeagus with setose area divided into two parts, apex of secondary flagellum simple.

This species is very close to Allocota viridipennis Motschulsky. We didn’t find significant difference between their male genitalia. These two species can be distinguished by different color on elytra and ventral side, and also by different distribution ( Map 6 View Map 6 ).

Description.

Body length 6.4-8.2 mm; head and pronotum reddish yellow to dark brown; mouthparts yellowish brown, apices of terminal palpomeres paler; 1st antennomere usually slightly paler than the remaining antennomeres; elytra metallic green to cupreous green, sometimes disc with a more or less distinct reddish patch, elytral suture and lateral margins yellowish or metallic; legs reddish yellow to dark brown, usually the same color as pronotum, sometimes slightly darker on apex of femora; ventral side the same color as pronotum; metasternum and abdomen not darker than prosternum. Head glabrous, without punctures, microsculpture indistinct; males with terminal labial palpomeres fusiform, slightly expanded in middle. Pronotum glabrous,cordiform, widest at apical one-third; ratio PW/PL 1.20 to 1.35; pronotal base briefly but distinctly lobed; disc moderately convex, microsculpture indistinct, slightly transverse, without punctures; front angles with a few very fine short setae (distinctly shorter than in Allocota cyanipennis ); lateral margins rounded, slightly expanded in middle, strongly sinuate before hind angles; lateral explanate areas moderately wide, without punctures; hind angles usually acute and sharp; basal foveae very shallow, without punctures; median line very fine, usually indistinct. Elytra with striae slightly distinct, finely punctate; intervals slightly convex, without accessory setae, with a row of very fine punctures; usually with very faint isodiametric microsculpture; 3rd and 5th intervals with four to ten setigerous pores, their positions variable; 7th interval without setigerous pores; setae on lateral margins very fine and short, hardly visible. Legs. Proti biae with cleaning spur absent ( Fig. 140 View Figures 138–157 ); males with adhesive hairs well developed (two whole rows) on first two mesotarsomeres, rudimentary (two rows, weakly present near apex) on 3rd mesotarsomere. Male genitalia with median lobe of aedeagus stout, slightly bent to right side near apex in dorsal view, right margin slightly curved before apical lamella; apical lamella placed on right side, narrow, slightly elongate; internal sac with setose area divided into two parts; apex of secondary flagellum simple, not expanded; trumpet-form expansion with ventral margin more or less expanded ( Figs 82 View Figure 82 , 83 View Figure 83 ). Female genitalia. Spermatheca straight, tubiform, moderately long; apical part not distinct widened, with very faint ring-sculpture; spermathecal gland inserted near middle of spermatheca, not branched, slightly thickened at base, not longer than spermatheca ( Fig. 133 View Figures 132–137 ). Apical segment of ovipositor very short, slightly longer than width; outer margin straight; inner margin curved, with fine setae on apical half; membranous extension short and wide ( Fig. 118 View Figures 111–125 ).

Distribution

( Map 6 View Map 6 ). Japan, China (Shaanxi, Guangdong, Hainan, Yunnan), Vietnam (Tonkin), Laos, Nepal.

Notes on synonym.

Jedlička (1963) described Taicona perroti based mainly on the distinct reddish patch on elytral disc and bluish metallic color being different from Allocota aurata . These characters are always present in specimens from Tonkin or Hainan. But we didn’t find any difference between this “form” and the typical " Allocota aurata " from Japan in male genitalia or external characters except color. The other characters mentioned by Jedlička (1963), such as differences in pronotal shape and punctures on striae, vary among individuals, so we herein synonymize Taicona perroti Jedlička with Taicona aurata Bates.

Geographical variation.

A total of four different color forms was found in this species from different localities: (1) typical " Allocota aurata " comes from Japan, and was also found in Shaanxi and Guangdong of China; the head and pronotum are reddish brown; elytra metallic green, disc slightly reddish, not forming distinct patch ( Figs 18 View Figures 13-18 , 51 View Figures 49–54 ); (2) specimens from Tonkin, Hainan, Laos and Nepal, namely " Allocota perroti ", with head and pronotum vivider compared to specimens from Japan, elytra metallic green, slightly bluish, disc with large reddish patch reaching 5th or 6th interval, the patch much more distinct than in the "typical Allocota aurata " ( Fig. 19 View Figures 19–24 ); (3) specimens from the southern part of Yunnan (Xishuangbanna) with head, pronotum and legs dark brown; elytra metallic green, disc not reddish ( Fig. 21 View Figures 19–24 ); (4) specimens from the western part of Yunnan (Fugong, Tengchong, Ruili) with head and pronotum slightly darker than in the "typical form", elytra distinctly cupreous, disc not reddish ( Fig. 20 View Figures 19–24 ). These forms were only different in color, but other characters including male genitalia are the same. So we consider them as geographical variation rather than distinct species or subspecies.

Remarks.

This species has male genitalia very similar with Allocota viridipennis Motschulsky implying they could be synonyms. However, their constant differences on elytral and ventral color, as well as the distribution gap make us quite doubtful to synonymize them at present. Therefore, we keep them as distinct species before more specimens are available, especially those from Indo-China.

The shape of right paramere apex is quite different among specimens of this species. ( Figs 103, 104 View Figures 95–110 ) According to examined materials of some other species in Physoderina , we speculate that in this subtribe the shape of right paramere is an intraspecifically variable character, but less variable between different genera ( Figs 95-110 View Figures 95–110 ). Therefore, this character has no taxonomic importance at both species and genus levels.
