Description (holotype). Shell of medium size for the genus (SL 39.0 mm), elongate oval, slender. Protoconch low dome shaped, smooth, creamy coloured. About one whorl with distinct shallow suture, further suture overlaid by callus. Protoconch borders indistinct, rendering whorl count impossible. Spire moderately high, conical; with weakly convex sides. Primary callus rather thin, covering all remaining whorls; surface of callus weakly glossy, strongly microshagreened. Spiral striation visible through primary callus on apertural side of shell. Secondary callus moderately thick, forming tongue-shaped pad extending to right-ventral side of last whorl and continuing up as pad reaching suture of antepenultimate whorl. Surface of secondary callus strongly microshagreened and similar to that of primary callus. Body whorl cloak glossy, covered by distinct very narrow, wavy, and closely spaced spiral striation; distinct but very narrow lighter band in lower part adjoining anterior band. Olivoid groove not pronounced. Rear edge of anterior band distinct in a shape of sharp step, obscured in ending part of last whorl adjacent to aperture lip. Anterior band with darker narrow brown band in lower part of upper anterior band followed by a lighter band adjacent to border between upper and lower parts of anterior band. Lower anterior band separated by distinct elevated ridge, darker orange-brown with irregularly spaced still darker transverse lines. Upper anterior band nearly flat, very weakly concave medially, lower anterior band nearly flat. Lower anterior band narrower, separated from plication plate by deep and broad groove. Plication plate with 7 equally developed ridges. Columella with few weak spiral cords in lower part, crossed by two distinct brown spiral bands, the upper narrower and corresponding to darker spiral band of the upper anterior band, the lower broader band corresponding to abapical part of lower anterior band, adjacent to plication plate. Aperture narrow oval, acute posteriorly, widest medially; outer lip sharp, nearly orthocline. Siphonal notch moderately deep, asymmetrical. Body whorl cloak orange-brownish, with bluish tint on dorsal side and irregularly spaced axial darker brown lines of varying width, especially distinct on dorsal side. Primary and secondary calluses of more intense orange, plication plate creamy.

Radula ( Fig. 9B–C View FIGURE 9 ) studied in one specimen (MNHN-IM-2023-449 – SL 31.8 mm), typical for the genus, of about 75 transverse rows of teeth, 5 nascent. Radula about 1.92 mm in length (10.1% of AL), membrane about 175 µm in width (0.92% of AL).

Diagnostic cox-1 sites. 'G' in the site 4, 'A' in the site 175.

Remarks. The species is moderately variable in shell slenderness and colouration. At least one specimen is very light ( Fig. 11I–K View FIGURE 11 ) with light yellowish primary and secondary calluses and light-creamy body whorl cloak.

Generally, the new species strongly resembles T. glans , differing, in several characters. First, protoconch is retained in all examined specimens of T. heraldei , even dead-collected ones, while it is always missing and upper whorls are strongly eroded in T. glans . Secondly, most of the specimens of T. heraldei sp. nov. have the two distinct and narrow spiral brown bands crossing the columella ( Fig. 12C–D View FIGURE 12 ), while only one distinctly does it in T. glans ( Fig. 12A–B View FIGURE 12 ). It should be mentioned, that the second, upper band is fading in dead collected shells and can be absent in some lightly-coloured live specimens (e. g.: Fig. 11I–K View FIGURE 11 ). Finally, T. glans can attain a larger size, being up to 48 mm in SL vs 39 in T. heraldei sp. nov.

One specimen was found attached to the shell of Xenophora pallidula (Reeve, 1842) , collected in the Philippines ( Fig. 13 View FIGURE 13 ).

Etymology. The species is named after Prof. Francisco M. Heralde III, from the University of Philippines, Manila with whom (at that time a PhD student) we processed the specimens of the new species during the PANGLAO 2005 expedition, in recognition of his participation in the “bar-code team” of MNHN expeditions to the Philippines.
