Type material: Holotype (91.8mm long x 66.9mm wide x 27.2mm high) deposited at Paris National Museum of NaturalHistory, France with Registration No: MNHN-IM-2000-38115.
Other material: Paratype 1 (92.5mm); Paratype 2 (92.3mm), Paratype 3 (96.3mm), Paratype 4 (67.5mm) and Paratype 5 (82.9mm) in Dr Thach collection. All types from type locality.
Type locality: Nha Trang area, Khanh Hoa Province,
Central Vietnam.
Habitat: Rocky shores at l-5m.
Diagnosis: The new species is characterized by very large adult size, thick and inflated shell, greenish radiating stripes, very elevated principal ridges at dorsal side.
Description: Shell large, swollen with length range 67.5-96.3mm, elongate-ovate in outline and longer than high. Spire tall, sutures distinct. Shell width 73.3% and shell height 29.3% of shell length (see Table 1). Outer surface ornamented with well visible greenish or whitish radiating stripes. Sculpture at body whorl consists of about eight green, zigzag, granulose ridges directed anteriorly which are crossed at the middle of dorsal side by nine granulose ridges directed posteriorly; narrow spiral grooves crossing these ridges at terminal part of body whorl. Open holes moderately elevated and 4-6 in number. Area located between series of holes and outer edge wide, concave, ornamented with green lines and sculptured with three spiral ribs crossed by oblique axial ribs. Aperture very wide with external ridges well visible within, outer lip slightly convex and moderately thick. Columella very broad and grooved at the middle, apex visible at interior side. Color externally purple-brown and internally iridesecent with pink and blue glazes.
Etymology: The new species is named in honor of Prof. Philippe Bouchet from France for his great contribution to the world malacology.

Comparison: The new species is quite different from Haliotis ovina Gmelin, 1791 of other countries. It is distinguished mainly from Haliotis ovina of neighbouring country Thailand (Fig.l of WoRMS) in following characters: (1) much wider shape, (2) more inflated shell, (3) more elevated spire, (4) principal ridges narrower at posterior part of dorsal side and longer, broader, more undulate at anterior part, (5) radial
ridges directed anteriorly and more prominent along outer lip, (6) open holes at dorsal side larger, more elevsted and more numerous, 4-6 versus 3-5 holes after Geiger & Poppe (2000), (7) different colors, (8) outer lip more ascending, (9) wider columella, (10) apex visible at ventral side with different sizes, (11) different localities, Vietnam versus Thailand.
There are also obvious differences between the new species and Haliotis ovina Gmelin, 1791 from Philippines (Fig.2) illustrated in WoRMS at both dorsal and ventral sides.
Haliotis ovina Gmelin, 1791 illustrated in Fig.4a,4b, Plate 26 of Geiger & Poppe (2000) is distinguished mainly from the new species by (1) smaller adult size, 57.0 versus 91.8mm in length, (2) less elongate shape, (3) not swollen shell, (4) less elevated spire, (5) area between columela and series of holes much narrower, not visible at posterior end of dorsal side, (6) spiral ribs more prominent, (7) radial ridges broader and more elevated, (8) presence of many riblets at columella, (9) outer lip much thinner and less convex, (10) holes more erected, (11) outer edge visible above columella at ventral side, (12) different color, (13) different localities, Thailand versus Vietnam. These numerous differences are sufficient to distinguish them into two species.
