Characters. The original description of C. kazukoae refers to colouration of immature individuals of both sexes ( Asahina 1984).

Immature males ( Fig. 1a View FIGURE 1 ) have the dark elements of the colouration brown rather than black, while the pale elements are at first creamy- and later bluish-white. The dark dorsal part of the synthorax has a very peculiar stripy appearance. Its ground colour is pale brown. There is a darker brown stripe going over the middorsal suture, which in turn is bordered by a pair of pale stripes with a diffuse lower margin. A distinct pale streak, of the same colour as the lower part of the synthorax, goes along the mesepisternum, accompanied by a blackish streak at its dorsal side and a darker brown diffuse border at its ventral side. A next pale streak covers the mesopleural suture; it is narrow and diffuse, but its posterior end is expanded and distinct and is bordered by a blackish stroke at its dorsal side . The ventral border of the synthorax dark part at the mesepimeron, except for its anterior part, is bordered by another blackish streak. The upper part of the head is light brown with irregular blackish stripes, one in front of antennae, the second between the antennae and the central ocellus, broadest behind the lateral ocelli, and there is a pair of lateral darker areas along the compound eyes and a pair of distinct light-bluish occipital stripes.

Submature males ( Fig. 3 View FIGURE 3 ): The diffuse pale stripes over the middorsal and mesopleural sutures darken and fade, while the pair of distinct mesepisternal streaks and the distinct posterior part of the mesepimeral streak become contrasted bright-bluish ( Fig. 5f View FIGURE 5 ). The blackish elements on the top of the head merge with each other, leaving irregular and interrupted brownish stripes between the lateral ocelli and compound eyes and spots around the central ocellus ( Fig. 5h View FIGURE 5 ).

Fully mature males ( Figs 1b View FIGURE 1 , 2 View FIGURE 2 , 5g View FIGURE 5 , i–j) correspond to the original description of C. megumii ( Asahina 1984) . The synthorax has become distinctly bicolored, bright azure blue and saturated black, its dorsal side black with only a pair of distinct blue mesepisternal streaks ( Fig. 5g View FIGURE 5 ). The pair of dorsal brownish spots on the prothorax disappears but the anterior lobe remains largely brownish ( Fig. 5j View FIGURE 5 ). The top of the head has become black with only a pair of narrow brownish streaks between the lateral ocelli and compound eyes and some vestigial spots at the central ocellus, while the occipital streaks are bright blue ( Fig. 5g View FIGURE 5 ).

Females exhibit a similar change of colouration while ageing, but the colouration of immature individuals is usually of a more yellow hue, while the darkening of the dark pattern elements in mature females is not as complete as in males. Therefore, the diffuse brownish stripes can still be seen on the dorsal side of the synthorax along with the pair of distinct blue streaks ( Fig. 2 View FIGURE 2 ).

Occurrence and seasonality. Immature stages are encountered more frequently than completely mature individuals. It is still unclear if the species has some regular seasonality. Hämäläinen & Pinratana (1999) summarised the occurrence of C. kazukoae ( thus of immature specimens) as September–January and that of C. megumii (mature specimens of C. kazukoae ) as May –October. In Cambodia O.K. observed mature individuals in December and August and immature individuals in March and April. In Phú Quốc immature specimens of the species were recorded by T.K. in January and April.

Distribution. The Sankamphaeng Mountains in eastern Thailand and the entire Cardamonean region, which includes the Cardamom Mountains, extending from the eastern Thailand to south-western Cambodia, and the adjacent islands including Phú Quốc ( Fig. 6 View FIGURE 6 ). The species is known from Nakhon Nayok, Nakhon Ratchasima, Sra Kaeu, Chanthaburi, and Trat Provinces of Thailand, from Koh Kong and Preah Sihanouk Provinces of Cambodia, and from the islands of Koh Rong ( Cambodia) and Phú Quốc ( Vietnam).

The species has not been recorded from Pursat and Kampot Provinces of Cambodia and the islands of Ko Chang, Ko Kut ( Thailand) , Koh Kong and Koh Rong Samloem ( Cambodia) but , as can be inferred from the known distribution and biogeographical considerations, is expected to occur there as well .

Habitat. Coliccia kazukoae inhabits lowland evergreen tropical forests, where it occurs at small rivers and brooks (including those disappearing in the dry season) which flow in shady, often rocky valleys and ravines (see Kosterin 2010: Fig. 21; Kosterin 2011: Fig. 32), or at seepages in the major river valleys (see Kosterin 2010: Fig. 10 View FIGURE 10 ). In Phu Quoc the species was observed in the forest away from stream valleys (dried up in the dry season), perching on twigs and herbs.
