Arthroleptis poecilonotus Peters, 1863  

( Fig. 3A, B View FIG )

COLLECTION MATERIAL. — Burkina Faso   10 subadults ( SVL 12.1- 20.1 mm); Bobo-Dioulasso , near Nasso; 11.18803°N, – 4.29741°W; 420 m a.s.l.; VII.1970; M. Lamotte leg.; MNHN-RA-2008.1055, 2008.1056, 2008.1057, 2008.1058, 2008.1059, 2008.1060, 2008.1061, 2008.1062, 2008.1063, 2008.1064 GoogleMaps   .

FIELD MATERIAL. — Burkina Faso   2 ♀ ( SVL 27.6-28.1 mm), 5 ♂ ( SVL 24.4-26.5 mm), 3 subadults ( SVL 16.6-18.3 mm); Nasso , Kou Forest; 11.18888°N, – 4.43935°W; 320 m a.s.l.; 7-9.VIII. 2018; H. J. Ayoro & A. Ohler leg.; gallery forest; hand capture GoogleMaps   .

DESCRIPTION. — 20 specimens examined. Small frogs with a blunt snout, short head and a concave tympanum; slender limbs, the inner metatarsal tubercle long and prominent. Adult males and females with protruding palmar and supernumerary tubercles on fingers. Tubercles absent on toes. Dorsum feebly granulated. In life, dorsum grey, brown or reddish-brown coloured. Sometimes an hourglass pattern present on back ( Fig. 3A, B View FIG ). Venter with whitish or brownish, smooth skin. As other Arthroleptis   species (e.g. Blackburn 2009; Blackburn et al. 2010), presence of an elongated third finger, and transparent spines on second and third fingers in adult males.

HABITAT. — The historical specimens and the recent samples of A. poecilonotus   were from Kou Forest ( Fig. 2E View FIG ). At this site, males were seen at night on leaves of shrub and grass at heights varying from 0.2- 1 m. Females and subadults were seen hiding in leaflitter. The species may occur in other gallery forests along the major rivers (Mouhoun, Comoé and Pendjari rivers) in the western and southern part of Burkina Faso as well ( Lamotte 1967b). It was found in a forest close to a waterfall near Pendjari National Park in Benin ( Nago et al. 2006), in Togo ( Segniagbeto et al. 2007), in Ivory Coast ( Lamotte & Perret 1963; Lamotte 1967b; Barbault & Trefaut-Rodrigues 1979; Rödel 2000; Rödel 2003; Rödel & Ernst 2003) and in Nigeria ( SchiØtz 1964, 1967; Leaché et al. 2006; Onadeko 2016).

TAXONOMIC REMARK. — As stated in Rödel & Bangoura (2004) and Blackburn (2010), it is currently not possible to assign these West African Arthroleptis   taxa with certainty to one of the various available names, as intra-specific variability equals or surpasses interspecific differences. As actually understood, A. poecilonotus   has an extended distribution range, including West, Central and parts of East Africa ( Frost 2019) and probably recovers a group of species. Type locality is in West Africa, in south-eastern Ghana. Further studies, in particular including topotypical material, are needed for taxonomic decisions.
