De Vos, 14 Sep. 1985.</p> <p>Redescription</p> <p>Based on 87 specimens including lectotype and three paralectotypes. Morphometrics and meristics are given in Table 5. Small to medium-sized species [maximum size, 163 mm SL (Greenwood 1959)] with moderately compressed body; dorsal head profile fairy steeply sloping, straight or decurved, becoming concave in large individuals. Mouth horizontal or slightly oblique. Jaws equal anteriorly or lower somewhat projecting; posterior tip of maxilla reaching, or almost reaching, vertical to anterior orbital margin. Gill rakers short and stout; generally 8 or 9 [7(f1), 8 (f30), 9 (f49), 10 (f7)] on the lower limb of the first gill-arch. Flank scales around lateral line ctenoid, elsewhere cycloid; generally 29-32 longitudinal line scales, excluding the small scales on caudal fin base [26 (f1), 27(f2), 28 (f5), 29 (f8), 30 (20), 31 (f29), 32 (f14)]; cheek with 3 (f24), 4 (f57) or 5 (f5) series of scales; scales between pectoral and pelvic fins 4 (f35), 5 (f40) or 6 (f8) [rarely 3 (f1)]. Dorsal fin spines 17-19 [rarely 16 (f2) or 20 (f2)], soft rays 7 (f29) or 8 (f51) [occasionally 6 (f2) or 9 (f5)]. Anal fin spines 4-7 [(4 (f7), 5 (f63), 6 (f17) and 7 (f2)], rays 6 (f9), 7 (f56) or 8 (f20) [rarely 9 (f2)]. Pectoral fin rays 13 (f32) or 14 (f54) [rarely 15 (f1)]. Caudal fin rounded. Posteriormost teeth in outer row of upper jaw unicuspid. In small specimens, outer row teeth unequally bicuspid and relatively stout (occasionally only stout unicuspid teeth in small specimens) becoming a mixture of weakly bicuspid and unicuspid in large specimens. 28-48 outer row teeth in upper jaw and 20-42 outer row teeth in lower jaw with numbers increasing with size, 1 or 2 (occasionally 3) inner rows of small tricuspid or occasionally unicuspid teeth in both lower and upper jaws. LPJ triangular, longer than, or almost as long as, wide (LPJ width 78.1-108.5% of LPJ length); lateral teeth in the posterior rows slender and cuspidate, the central two to four (occasionally six) rows with a mixture of molariform (anterior part of the dentigerous area) and enlarged but cuspidate teeth. The specimens from Lake Victoria have a more massive LPJ and a greater proportion of molariform teeth compared to the similarly sized specimens from other lakes and rivers in the Victoria basin.</p> <p>Colour pattern of live specimens</p> <p>See Fig. 5 for general appearance. Anteriorly and dorsally grey yellowish, posterior-ventrally grey greenish to bluish. A dark band, continuous with lachrymal stripe, runs obliquely backwards through, or a little behind, the eye to near the gill opening. Lower jaw faint grey bluish. Fins grey yellowish, dorsal fin somewhat darker and with blackish spots on soft part; caudal fin with similar spots, pelvic blackish distally; anal fin of specimens (males and females) larger than 80 mm SL with 2-3 horizontal rows of bright orange-yellow ocelli. In specimens less than 80 mm SL, anal ocelli may be absent or hardly visible. According to Greenwood (1959), sexual dimorphism is less marked in this species than in other haplochromine cichlids and the colour pattern of breeding males resembles that of females except that the soft dorsal fin is more densely spotted, the spinous dorsal and entire caudal fin are suffused with maroon, and the cephalic marking are more intense than in females.</p> <p>Colour pattern of preserved specimens</p> <p>General appearance greyish-brown to brown, lighter ventrally; five or six dark transverse bars often interrupted ventrally on the flanks (lacking in some specimens). No mid-lateral band present. A vertical, or posteriorly directed, blackish bar below the eye, runs to posterior corner of mouth, occasionally extending onto lower jaw. Blackish dots arranged in interrupted horizontal rows on soft dorsal fin and in interrupted vertical rows on caudal fin; these are strongly marked in large males. Edge of fins dark to blackish, anal ocelli in males, when present dark grey.</p> <p>Distribution</p> <p>Known from lakes Edward, Victoria, Kyoga, George, Nakavali and Kachira, and the rivers and streams associated with these lakes, including the Semliki (Greenwood 1959). The species has been introduced into many areas of East Africa for biological mollusc control (Greenwood 1965b; Welcomme 1988) and now has a widespread distribution within the Victoria basin (Kenya, Uganda &amp; Tanzania including the Upper Akagera basin in the Bugesera depression (Burundi &amp; Rwanda)). Slootweg (1989) discussed the possibility of the introduction of A. alluaudi into northern Cameroon (Benue River basin), which indeed took place (Vreven et al. 2007). There are no reports that the introduction of this species in the Congo Republic, the Democratic Republic of Congo, the Republic of Central Africa and Zambia (Welcomme 1988) has succeeded.</p> <p>Ecology</p> <p>According to Greenwood (1959), A. alluaudi is not confined to a particular type of substrate and is ubiquitous in all areas where the water is less than 20 m deep. It also occurs in papyrus swamps and feeds mainly on molluscs. Ntakimazi (1985) confirmed the occurrence of the species in papyrus swamps in Lake Rweru, Bugesera depression (Burundi &amp; Rwanda). However, he did not find any shell fragments of snails in the gut contents of 80 specimens, but instead found a large amount of organic debris, algae, fish remains and benthic invertebrates. He concluded that A. alluaudi might be an omnivorous species that switches to the most abundant food source in its environment. He noticed, however, that the molariform teeth of the lower pharyngeal jaw are well developed, and suspected they are instrumental in crushing the exoskeletons of aquatic invertebrates and vegetal debris.</p> <p>Reproduction</p> <p>The species is a mouth-brooder. Most of the females caught in December 2012 in Lake Rweru in Burundi had fry in their mouth. Though its breeding period is not well documented, the species may reproduce at the end of the short rain season from November to December. Whether this is the only reproductive season cannot be determined from our data.</p></div> 	http://treatment.plazi.org/id/03888791BC2DE802FDFCB2999EA9FAF9	Public Domain	No known copyright restrictions apply.

Lockley, 11 Apr. 1953; BMNH 1953.11.4 (18 specimens), paratypes, 59.2- 79.8 mm SL, same data as holotype.</p> <p>Description</p> <p>Based on the holotype and 85 specimens. Morphometrics and meristics are given in Table 5. Small to medium sized species (max 111.3 mm SL) with moderately compressed body. Snout pointed or slightly concave. Eye diameter as long as, or shorter than, interorbital width. Caudal peduncle variable, ranging from somewhat longer than deep to just slightly deeper than long. Gill rakers on lower part of the anterior arch thick and stout, 8-10 [8 (f33), 9 (f41), 10 (f11)], last three or four reduced to small nubs. Upper and lower jaws with 1-3 inner rows of tricuspid teeth. Outer series in both jaws composed of unequally bicuspid and sometimes compressed teeth, only slightly cuspidate or conical in the posteriormost part of both jaws. Tooth number of outer rows increases with size: 32-56 in upper jaw and 23-44 in lower jaw. Flank scales around lateral line ctenoid, elsewhere cycloid; generally 29-32 longitudinal line scales, excluding the small scales on caudal fin base [28 (f3), 29 (f10), 30 (29), 31 (f26), 32 (f14), 33 (f2)]; cheek with 3 (f49) or 4 (f35) [rarely 5 (f1)] scale rows; scales between pectoral and pelvic fins 4(f51) or 5 (f30) [rarely 3 (f1) or 6 (f2)]. Dorsal fin spines 16-18 [exceptionally 19 (f1)], soft rays 8-10 [8 (f8), 9 (f52), 10 (26)]. Anal fin spines 3-4 (usually 3), rays 8 (f19), 9 (63) or 10 (f4). Pectoral fin rays 13 (f47) or 14 (f26) [rarely 11 (f1) or 12 (f2)]. Caudal fin rounded. LPJ triangular, longer than, or almost as long as, wide (LPJ width 83.3-102.8 % of LPJ length); its teeth in the lateral external rows slender and cuspidate, the central two to four rows with a mixture of molariform (anterior part of the dentigerous area) and enlarged but cuspidate teeth.</p> <p>Colour pattern of live specimens</p> <p>See Fig. 6 for general appearance. Dorsally and dorso-laterally dark grey-yellowish, orange yellowish on opercle, upper part of cheek, chest and belly. Lips and lower part of cheek iridescent blue. Fins orange yellowish, dorsal with red edge, more pronounced posteriorly. Anal fin with 3-5 horizontal rows of bright orange-yellow ocelli. Females with similar but smaller ocelli. Caudal fin with black dots arranged in 6-8 more or less regular vertical rows. While general appearance remains the same, live colour pattern appears influenced by characteristics of the water in which the individuals live. Rusizi specimens caught in water with a high conductivity (more than 250 µs/cm) and muddy blackish bottom substrate in the Gatumba swamps near Lake Tanganyika during the rainy season have a darker colour pattern (Fig. 6B). Specimens caught in the pools associated with the Rusizi River more to the north and in marginal vegetation of the Malagarazi River are generally lighter coloured (Fig. 6A).</p> <p>Colour pattern of preserved specimens</p> <p>General appearance dark brown for recently preserved specimens turning lighter grey or dark grey after a couple of years of preservation. Fins dark grey, edge of anal and anterior part of dorsal and pelvic fins dark brown to blackish. No mid-lateral band present.A large blackish blotch at upper posterior end of gill cover, may be vague in some specimens. A blackish vertical bar below, or behind, the eye in all recently preserved specimens; this bar may disappear in specimens kept for some time in alcohol. Blackish dots arranged in interrupted horizontal rows in posterior portion of soft dorsal fin and in interrupted vertical rows in caudal fin. Anal ocelli always present but less visible distally, where anal fin is dark brown to blackish.</p> <p>Distribution</p> <p>Known from the Rusizi, Lukuga and Malagarazi basins and from the Luiche, a small affluent of Lake Tanganyika just north of the Malagarazi River delta. The species apparently also enters the lake as it was collected by Brichard in 1973 from the harbour of Bujumbura; in addition, De Vos et al. (2001) mentioned its presence at the harbour of Ujiji near Kigoma in Tanzania. Its presence in other affluents of Lake Tanganyika needs to be confirmed.</p> <p>Ecology</p> <p>Astatoreochromis straeleni is primarily a riverine species (Greenwood 1954; Poll 1956, 1974), prefering clear water (pers. obs. GB). In the Malagarazi basin, no specimen was found in the main channel. The most important catch was made during the rainy season when specimens were caught in swampy flooded areas. The species was also caught in marginal vegetation of the Mazimero River, a small affluent of Malagarazi, with a high water transparency. In the Rusizi basin, the species was mainly caught in the Gatumba swamps where it is more abundant than in the Malagarazi basin; here also it was found mainly in vegetated areas with clear water. It was also common in the small swampy pools associated with the Rusizi River. The species was never caught in nor reported by the local fishermen from the main course of the Rusizi River. Greenwood (1954) reported the species to feed mainly on snails, ostracods and insects in the Malagarazi basin. Examination of stomach and gut content of 12 recently collected specimens (January 2011) from the Rusizi found snails (entire and fragmented shells) together with adult insect fragments (wings) and other invertebrate remains in four specimens. Two specimens contained some adult insect remains and other invertebrate material, but no snails. The guts of three other specimens contained a large amount of debris, sand and small undigested plant fragments. Finally, three mouthbrooding females had empty guts.</p> <p>Reproduction</p> <p>The species is a mouth-brooder but nothing has been reported about its breeding period. Among the specimens captured in the Malagarazi in December 2008 and in the Rusizi in January 2011, females were found with ovarian eggs at different developmental stages in their gonads. Those caught in January appeared to be at a more advanced stage and almost mature for spawning (diameter: 1.9-2.6 mm). Conversely, amongst the specimens caught in the Rusizi basin in February 2009, no females with developed eggs in their gonads were found. So, most probably the species reproduces at the start of the short dry season from December to January. Whether this is the only reproductive season cannot be determined from our data.</p></div> 	http://treatment.plazi.org/id/03888791BC28E81FFDCAB4E19DE7FD57	Public Domain	No known copyright restrictions apply.
