03FFF37EFF924D6E3FEFFE08FA91F8C3.taxon	discussion	Remarks: Eupasiphae ostrovski n. sp. differs frOm the Other fOur species Of the genus in the presence Of a strOng carina at carapace, beginning at branchiOstegal tOOth and bifurcating at hepatic regiOn, the superiOr branch cOntinues tO almOst pOsteriOr carapace end, Where it turns up and bifurcate in Other tWO carinae that runs parallel tO superiOr branch Of branchiOstegal carina directing tO anteriOr carapace regiOn and cOnnecting One tO anOther near the hepatic regiOn (Fig. 1 A), the inferiOr branch is shOrt and fOllOWs dOWn diagOnally nOt reaching carapace inferiOr margin, besides that the middOrsal carina Of carapace is unarmed in the anteriOr 0.8, While armed With 0 – 3 small teeth in the pOsteriOr 0.2 (Fig. 1 A). Eupasiphae ostrovski n. sp. appears clOsest tO E. paucidentata and bOth species share a shOrt and high rOstrum; third maxilliped basis With epipOd; first and secOnd pleOmeres dOrsally rOunded and a small tubercle at the inner anteriOr margin Of the eyestalk. HOWever, Eupasiphae ostrovski n. sp. has the anterOdOrsal margin Of carapace WithOut teeth (Fig. 1 A) (vs. three teeth in E. paucidentata); the branchiOstegal tOOth marginal (vs. submarginal in E. paucidentata); the first pereOpOd With 10 – 13 mOvable spines On merus (vs. 17 – 20 in E. paucidentata), and its basis With a small pOsterOdistal tOOth (Fig. 2 D) (vs. unarmed in E. paucidentata).	en	Rodrigues, Thaiana G.
