Í mm

Type locality: Australia?

Material examined: ZUTC ann. 2039, 2230, 2234.

Measurements (n = 9): Length 17.55–24.18 (21.19), width 4.3–8.19 (6.6).

Remarks: According to Wehe (2006), there are microtubercles on the elytra of Thormora jukesii , usually confined to the lateral part of the surface of the body. They are numerous from the second pair of elytra onwards. Additionally, small globular papillae are found scattered along the margin of the body. However, on specimens of T. jukesii found in Hengam Island, the microtubercles decreased from the second pair of the elytra onward, and globular papillae along the margin of specimens were missing ( Fig. 6c, f ).

Distribution: Th is is a new record for the Gulf of Oman.
