Ecpatia sciachroa Hampson, 1926

Barcode Index Number: BOLD:ACB3991

( Figs. 3 View FIGURES 1–5 a–b, 10a–b and 11)

This species was described from Sri Lanka and has been recorded from the Philippines Hampson, 1926. Thai specimens fit with E. sciachroa , though the concept of this one will however have to be revised because of the fairly wide geographic distribution currently shown by the taxon (from Sri Lanka to the Philippines) (A. Zilli NHM, personal comment).

Specimens found in Thailand: 1 male, Lampang, Muban Phichai, 30.v. 2009, 240 m, 18°18’15’’N, 99°31’06’’E, M. J. Pellinen leg., genitalia slide MJP111. 8 females, Lampang, Muban Phichai, 21.viii. 2007, 240 m, 18°18’15’’N, 99°31’06’’E, idem., 29.viii.2007, Lampang, Mon Kao Kaew, 04.ii. 2008, 300 m, 20°24’00’’N, 99°32’44’’E, Lampang, Muban Phichai, 03.v. 2009, 240m, 18°18’15’’N, 99°31’06’’E, idem., 12.v.2009, idem., 09.vi.2009, Lampang, Phraya Chae, 27.ix. 2009, 350 m, 18°17’75’’N, 99°56’02’’E, genitalia slide MJP112, Lampang, Phraya Chae, 23.xi. 2016, 350 m, 18°17’75’’N, 99°56’02’’E, genitalia slide MJP1156.All specimens collected by first author.

Morphological diagnosis. This species is slightly larger than most other Ecpatia species, with somewhat narrower forewings. Externally it differs from other Ecpatia species in its more hazy brown color and reniform stigma which is positioned diagonally from middle part of the costa to tornus. White area in hindwing is triangular, reaching almost the base. Male genitalia of E. sciachroa ( Fig. 8 View FIGURES 6–9 .) differ from E. longinquua by the broader saccus and juxta ( Fig. 13 View FIGURES 10–13 .). (Gen. slide from Teruko Fukuda)

Genetic characterization. The species with the barcode sequence most similar to that of E. sciachroa is E. spiculivalva (6.9%). The sequence of E. longinquua shows no difference from that of E. sciachroa in the barcode region, but we cannot verify the identity of the available specimen of E. longinquua in BOLD (mined from GenBank) as it is not associated with a specimen image.

Description. External characters. Wingspan of both sexes 25–26 mm. Frons smooth, lower half whitish with narrow scales and upper half dull red with wide scales. Labial palps upturned, medium size, covered with light grey and dark scales, third segment about bone third of the second segment. Antennae of males fasciculate, cilia quite short, only same length than flagellomere and filiform in females. Thorax, patagia and tegulae dark grey with wide scales. Legs dark grey, with reddish and grey tips on segments. Forewing variegated brown-grey with yellowish brown patches between postmedial and submarginal lines. Orbicular stigma small, reniform, diagonally stretched toward dorsum, yellowish brown. Postmedial line wavy, almost zigzag-like and partly double, cilia grey brown. Submarginal line unclear white, marginal line black and fragmentary. Hindwings dark-grey, with clear round white area. Underside dark grey, with narrow white sections in the middle parts. Hindwing venation same as in preceding species. Abdomen same color as wings, with tuft of scales on tergites 4–7, underside color grey mixed with white scales. Male genitalia. ( Figs. 9 View FIGURES 6–9 a–b). Uncus not especially narrow, bent, apically sharp, penicular process in tegumen large quadrangular, juxta unclear triangular, valvae with arrow-shape plate basally on costal margin, sacculus terminating in strong bifid harpe, cucullus small axe-shape, with setae and stronger spines, separated distally with narrow constriction from sacculus. Saccus obtuse-angled triangle. Vesica of aedeagus corrugated with small broad based cornutus and spatulate sclerite. Female genitalia. ( Figs. 10 View FIGURES 10–13 ) Papillae anales round, apophyses posteriores slightly longer than apophyses anteriores, narrow. Ostium bursae round, posteriorly v-shaped, broader than medium-long ductus bursae. Corpus bursae only slightly corrugated, pyriform with unclear posterior appendix.

The species was collected in Northern Thailand from various biotopes between 240– 350 m. in May–June and August–November.

Biology. Preimaginal stages of the new species are unknown.

Remark. Figures of this species are illustrated in the Moths of Thailand Vol. 3, part two ( Kononenko & Pinratana 2013) as unidentified sp. Plate 42, no 53–54.
