FBname: Obama’s Teleogramma
Comments: Known only from a few rock outcrops located along a 40 km stretch of the middle Congo River, just upstream of Pool Malebo, in the Democratic Republic of Congo.  In August 2011, when water levels in the main channel of the middle Congo River reached an historic low (July-September 2011), a series of rocky outcrops, which in previous (and subsequent) years had been completely submerged, became partially exposed and accessible for sampling; and it was only on these that specimens of <i>Teleogramma obamaorum</i> were collected.  Since only very few rocky outcrops were located, and most of the shoreline was comprised of sandy or reed-fringed banks, this suggests that the short stretch where all <i>T. obamaorum</i> specimens were collected may represent the entire distributional range of the species. The stomach and full length of gut of all collected specimens contained small, intact shells of two species of rissooidean gastropods (superfamily Rissooidea) but in most cases, no other food items were present; a few individuals with  some disarticulated remains of ephemeropteran nymphs.  The male and female of this species are monomorphic and distinguished externally only by examination of the genital papilla.  A female individual, although collected while reproductively active, also appeared to lack the pronounced red flush of color on the belly (reported to be observed with females of other <i>Teleogramma</i> species and most chromidotilapiines).  Fecundity appears to be low, the largest female examined (6.38 cm SL) contained only 19 ovoid eggs measuring approximately 0.02 cm in height and 0.18 cm at widest girth and the smallest female (5.19 cm SL) contained 15 eggs of a similar size (Ref. 104438).
