( Fig. 62B )

Euryrhynchina puteola De Grave, Piscart, Tuekam Kayo & Anker, 2017: 121 , figs. 1–3.

Type locality. Small well in Mbanga city, Littoral province ( Cameroon).

Distribution. Currently known only from the type locality ( Fig. 62B , orange circle).

Description. De Grave et al. (2017: 121, figs. 1–3).

Remarks. The morphological differences between E. puteola and E. edingtonae include the development of the podobranch on second maxilliped, the number of cuspidate setae on the uropodal diaeresis and the characters listed in the key above. Although De Grave et al. (2017) considered the podobranch on the second maxilliped of Euryrhynchina puteola to be absent, based on the drawings in their fig. 2F it is possible that the podobranch is actually present, but very poorly developed compared to that of E. edingtonae . It is also worth noting that the number of cuspidate setae on the uropodal diaeresis, another character used by De Grave et al. (2017) to separate the two species, overlaps in the maximum value for E. puteola (1–2 setae) and minimum value for E. edingtonae (2–3 setae). Since E. puteola is currently known only from male specimens, the distribution of appendices internae (an important character in the Euryrhynchidae ) is still unknown for the female pleopods.
