Polydictya chantrainei View in CoL – CONSTANT, 2009: 294 [key], 296 [distribution, compared with P. duffelsi Constant, 2009 View in CoL , intraspecific variation], figs 1 [distribution map], 9 [habitus, from Myanmar]. — CONSTANT & PHAM, 2017: 279 [listed], 280 [compared with P. drumonti Constant & Pham, 2017 View in CoL ], 285 [compared with P. grootaerti Constant & Pham, 2017 View in CoL ], 289 [keyed].

DIAGNOSIS. The species can be separated from all other Polydictya species by the following combination of characters: (1) tegmina with paler and darker areas forming cloudy effect ( Fig. 1 A View Fig ); (2) posterior wings with bright orange basal area extending to half-length and remaining part translucent brown with very narrow opaque band along sutural margin ( Fig. 1 A View Fig ); (3) frons with dorsal margin slightly projecting anterodorsally ( Fig. 1 B, D View Fig ), yellow-brown ( Fig. 1 D View Fig ); (4) protibiae slightly laminate, brown basally and black distally with pale yellowish ring in middle ( Fig. 1 A, C View Fig ); (5) abdomen red dorsally ( Fig. 1 A View Fig ); (6) genital segments orange.

The closest species are P. grootaerti Constant & Pham, 2017 from Vietnam ( CONSTANT & PHAM, 2017: fig. 3), P. khmera sp. nov. from Cambodia ( Fig. 6 View Fig ) and P. kuntzi Nagai & Porion, 2004 from Borneo ( Fig. 18 View Fig ), from which P. chantrainei can be separated by character (2): the three other species show the brown coloured part of the posterior wings entirely opaque.

TYPE MATERIAL EXAMINED. THAILAND: Holotype ♂: [Chiang Mai, Thailand , VI.2002] ( MHNL).

MALAYSIA: Paratype ♂: [Coll. P. Bleuzen, Cameroon Highlands, Malaisie, XI 1993] ( MHNL) .

NOTES.

On the label of the paratype, “ Cameroon Highlands ” is a misspelling of “ Cameron Highlands ” .

From the type series, only the paratype from Malaysia was examined in CONSTANT (2009). The present study allowed the examination of the male genitalia of a specimen from the type locality, Chiang Mai and revealed that the specimen from Laos attributed to P. chantrainei by CONSTANT (2009) actually belongs to a separate species, P. laotiana sp. nov. For this reason, the distribution map only shows the type location and the identity of the specimens from Malaysia and Myanmar as listed in CONSTANT (2009) require verification based on male genitalia.

ADDITIONAL MATERIAL. THAILAND: 1 ♂ ( Fig. 1 View Fig – dissected): Thailand , Chiang Mai, Sept. 2000 ( MNHN) .

SUPPLEMENTARY DESCRIPTION.

Measurements and ratios: LT: ♂ (n = 1): 21.6 mm; LTg/BTg = 3.0; BV/LV = 4.1; LF/BF = 0.87.

9 Male genitalia: ( Figs 2–3 View Fig View Fig ) pygofer, anal tube and gonostyli orange; pygofer higher than long, with posterior margin slightly curved in lateral view and with blunt dorsolateral process directed posterodorsally and laterally. Anal tube elongate, 1.42 times longer than broad in dorsal view, broader near apex; dorsal margin nearly straight in lateral view and abruptly curved ventrally near apex; apicoventral angle rounded in lateral view; lateral margins strongly sinuate in dorsal view, subparallel on distal half; apical margin excavate in dorsal view, apicolateral angles blunt in dorsal view; in posterior view, dorsal and lateral margins strongly rounded, ventral margin bisinuate and lateral lamina visible on a distance. Gonostyli elongate, subrectangular with posterior half wider and dorsal margin excavate on basal half in lateral view; strong lateral bifid tooth directed antero-ventrally at about half length; apical margin nearly straight medially. Aedeagus with endosomal process rather straight in dorsal view, curved ventrally on distal portion in lateral view; in dorsal view, widening from base towards apex and abruptly narrowing after mediodorsal small hook, laterodorsal margin

10 laminate on distal portion and with 5–6 irregular teeth directed laterally; in lateral view, laterodorsal lamina incurved and apex rounded; inflated phallus rather complex, symmetrical, with 3 pairs of membranous processes; dorsal pair projecting dorsally, large, broad and furcate on distal portion; median pair projecting posteriorly, with weakly sclerotized shaft more or less following endosomal process, hemi crescent-shaped and basally inflated ventrally; ventral pair with spiralate external structure and with internal weakly sclerotized shaft, inflated in median portion in lateral view.

DISTRIBUTION. Thailand (Chiang Mai Province) ( Fig. 4 View Fig ).
