Dark-brown oblique stripe from front of eye to upper lip, another dark-brown oblique stripe from below eye to jaw. Preoperculum and opercle with various-sized brown spots. Pectoral-fin base with a dark dorsal spot. D1 with a horizontal band, darker and broader posteriorly. D2 with three oblique rows of small brown spots. Caudal fin with six vertical dark bands. In live specimens, dark pigmentation may be less pronounced than in preserved forms. In preservative (Figs 5, 7, 8A–E): Head and body dark brown; head darker, body paler ventrally. Five to eight dark-brown midlateral blotches along body, usually 6–7, forming narrow chevrons or X-shaped structures; rearmost midlateral blotch on caudal-fin base darkest and double, both blotches rounded, with posterior one larger. Upper body with greyish to dark brown motling and irregular blotches. Dark blotch in front of D1 more or less distinct. Interorbital area and snout usually dark brown. Dark-brown oblique stripe from front of eye to upper lip. Dark-brown oblique stripe from below eye to jaw. Preoperculum and opercle greyish to dark brown with irregular blotches of varying sizes. Pectoral-fin base with distinct brown spot dorsally, extending onto base of pectoral-fin rays. Pectoral-fin rays usually brownish. Mental frenum usually pigmented dark brown. Ventral surface of head and breast variably pigmented, sometimes dark brown to base of pelvic disc. D1 with distinct brown horizontal band on proximal part; outer part with diffuse tiny brown spots on interspinous membranes. D2 with three oblique rows of small brown spots. Caudal fin with 6–11 vertical brown to black bands. Pelvic disc and anal-fin rays and membranes darkly pigmented or grey.</p><p>Distribution and habitat: Glossogobius callidus s.s. is abundant in marine habitats, coastal lakes, estuaries, and lower reaches of numerous rivers along the south and east coasts of South Africa, from Pletenberg Bay in Eastern Cape north to Kosi Lake near the South Africa / Mozambique border in KwaZulu-Natal (Figs 2, 11). Te distribution range of this species overlapping with the southern range of G. hanisii sp. nov. sublineage I. Te materials examined in this study confirm their sympatric occurrence in the Zotsha and Keiskamma rivers.</p><p>Seoual dimorphism: Males have a conical urogenital papilla with a pointed posterior edge; females have a wider, trapezoid papilla with a villose posterior edge. Males grow larger (up to 104.1 mm TL) compared to females (max 86.8 mm TL). Morphometric and meristic characteristics overlap.</p><p>Etymology: Smith (1937) did not elucidate the origin or rationale behind the specific name.</p></div>	https://treatment.plazi.org/id/03BC6F321C23FFCE5FC5FB71B9FDB9A9	Public Domain	No known copyright restrictions apply.

Te small Glossogobius specimen (17.0 mm SL; see Greenwood 1994) found in the buccopharynx of a cichlid in March 1994 at Marico Oog, a major source of the Limpopo River system located 1500 km from the river’s mouth, also pertains to this species. Tis suggests that the species inhabits the upper reaches of the Limpopo system; however, further sampling and examination of material from this area are needed for confirmation. Te species has also been documented in south-eastern and eastern Madagascar, extending from Ambinanibe Lagoon north to Mangoro River system. Sublineage I of G. hanisii is found from Coega River in South Africa north to the middle reaches of Limpopo at the South Africa / Zimbabwe border, whereas records of this species in the Buzi and Zambezi systems in Mozambique, Malawi (Lower Zambezi), and Madagascar belong to sublineage II. Te presence of sublineage I in southern Mozambique, specifically in the Limpopo and Incomati river systems, is also anticipated. Te overall distribution range of G. callidus overlaps with the southern range of G. hanisii sublineage I, and their sympatric occurrence has been documented in the Zotsha and Keiskamma rivers.</p><p>Seoual dimorphism: Males possess a conical urogenital papilla with a pointed posterior edge, while females have a wider, trapezoid papilla with a fringed posterior edge. Males reach a larger size (up to 122.2 mm TL) compared to females (max 94.3 mm TL). Morphometric and meristic traits are similar between sexes.</p><p>Etymology: The species is named in honour of Mr Vuyani Hanisi in recognition of his long-standing and exceptional contributions to the NRF-SAIAB National Fish Collection. For over 17 years, Vuyani has played an important role in caring for the collection through day-to-day hands-on activities associated with the general curation. This honour is unique as, traditionally, this has mainly been given to scientists or collectors of specimens, but hands-on caring for one of the largest fish collections in the southern hemisphere is a substantial contribution.</p><p>Similarity with Glossogobius minutus Geevarghese and John, 1983 fom India: Glossogobius minutus, described from a set of 10 specimens from the Kerala coast of India, shows significant morphological similarities with G. hanisii sp. nov .. Key aspects include the squamation of the predorsal area (naked or minimally scaled), the structure of papillae Line 5 (double anteriorly), the number of pectoral-fin rays (18–19 vs. 18–20), and the colour patern (5–6 X-shaped midlateral blotches). However, G. minutus differs from G. hanisii sp. nov. in having deep reddish orange spots when fresh over the antero-dorsal region, especially over the nape and snout, the dorsal half of body, and the caudal fin and peduncle (vs. absence of reddish orange spots over the head and body), and lacking of a distinct predorsal blotch (vs. present) [morphological data for G. minutus is sourced from Geevarghese and John (1983)].</p><p>Comparison with other Glossogobius species from Africa and Madagascar</p><p>Glossogobius callidus and G. hanisii sp. nov. differ from G. ankaranensis, a blind cave-adapted species endemic to a subterranean river in the Ankarana massif of northern Madagascar, in the following characters.

(iii) Sensory papillae patern (Figs 10, 15, 17): Line 5 double (vs. single row); suborbital longitudinal lines (i.e. Lines 7–11), and lines underside of head (i.e. Lines 12, 13) all in single rows (vs. Lines 9, 10, and 13 double or triple); Line 1a on snout in single row (vs. double); Line 2a patchy (vs. single row); a short longitudinal line between Lines 14 and 15 present (vs. absent); chin partly covered with two clusters of papillae (vs. fully covered with proliferated papillae). (iv) Colour patern: distinct predorsal blotch present (vs. absent) (Fig. 9); body with 5–8 midlateral blotches comprising narrow chevrons or X-shaped structures, with rearmost blotch on caudal-fin base double, both rounded and the posterior one slightly larger (vs. five large grey brown saddles on back, alternating with five diffuse oval grey-brown midlateral blotches, with rearmost blotch on caudal-fin base triangular; colour patern is less pronounced in preserved specimens; Figs 16A, B, 18); proximal part of first dorsal-fin spine and membrane without a distinct dark brown spot (vs. a distinct dark brown spot present). (v) Horizontal eye diameter 19.9%–30.4% head length (vs. 14.7%–17.2% head length). (vi) Postorbital length 42.4%–50.4% head length (vs. 51.1%– 56.9% head length).</p><p>Glossogobius callidus and G. hanisii sp. nov. differ from G. tenuiformis (Fig. 16C, D) in the following characters.
