03860F09FF8DFFEFFF68D0D1DD3FFD6C.taxon	diagnosis	Diagnosis Body shield with only pedigerous somite 2 free. Urosome cylindrical and 3 - segmented. Antennule of female 16 - segmented with aesthetasc on 15 th segment. Antenna with 1 - segmented exopod and 3 - segmented endopod. Oral cone elongated. Mandible consisting of stylet and 1 - segmented palp bearing two distal setae. Maxilla without ornamentations. Maxillule bilobed. Maxilliped 4 - segmented. Legs 1 - 3 biramous, both rami 3 - segmented. Third endopodal segment of leg 2 with armature formula 1,2,2; third exopodal and endopodal segments of leg 3 with armature formula III, 1 + I, 3 and 1,2,3 respectively. Leg 4 totally absent. Free segment of leg 5 with 3 setae. Remarks: Parmulopsyllus gen. nov. shows the characteristics of the subfamily Parmulodinae. A single thoracic free somite between cephalothorax and abdominal pleural plate. Mandible not greatly lengthened and retaining a recognizable blade. Basal segment of maxillule small, with long inner lobe, and outer lobe about 1 / 3 total length of the inner one. Leg 4 absent; leg 5 present as in Entomolepinae, but considerably shorter (McKinnon 1988), or totally absent as Paralepeopsyllus Ummerkutty, 1961. Considering the swimming legs of the genera included in Parmulodinae, Parmulella has leg 4 similar to a knob or a monomerous rudiment and its leg 5 is leafshaped or clavate (Stock 1992). In Parmulodes, leg 4 is reduced to a minute distal seta and leg 5 is 1 - segmented and slightly elongated (Wilson 1944, Canário et al. 2019). Parmulopsyllus gen. nov. has leg 4 totally absent and leg 5 slightly longer than in Parmulodes but not as long as in Parmulella. Parmulopsyllus gen. nov. also differs from the other genera in its subfamily by having a 16 - segmented antennule instead of a 17 or a 18 - segmented antennule as in Parmulodes and Parmulella, respectively (Stock 1992, Wilson 1944); a 4 - segmented maxilliped instead of a 5 - segmented as both other genera, and a distinctive armature formulae on the third endopodal segment of leg 2 with formula 1,2,2 instead of 1,2,3 as Parmulodes and Parmulella (Stock 1992, Wilson 1944, Canário et al. 2019), on the third endopodal segment of leg 3 with formula 1,2,3 instead of 1,1,3 as in both other genera (Stock 1992, Canário et al. 2019). Etymology: ‘ Parmula ’ from the Latin little shield, added suffix ‘ odes’ (masculine) and ‘ psyllus’ from the greek meaning flea. Gender masculine.

03860F09FF8AFFE6FF68D611DACEFD77.taxon	etymology	Etymology. The specific name ‘ intermedius’ means intermediate in Latin, referring to the existence of 16 segments of antennule in the new species. This number of segments is intermediary when compared with the 17 - segmented S. adventicius Johnsson, 2000 and the 15 - segmented S. redactus Canário et al. 2012.	en	Borges, Camila, Farias, Amilcar, Mácola, Rosa, Neves, Elizabeth G., Son, Rodrigo Johns- (2021): A new Entomolepididae genus and a new species of Spongiopsyllus Johnsson, 2000 (Copepoda, Siphonostomatoida) and their association with Aplysina Nardo, 1834 (Porifera, Demospongiae) in Todos-os-Santos Bay, Bahia, Brazil.

03860F09FF8AFFE6FF68D611DACEFD77.taxon	discussion	Remarks Spongiopsyllus intermedius sp. nov. has all the characters of the genus Spongiopsyllus such as a body shield covering the urosome, except for the tip of the caudal rami, three postgenital somites, and reduction in the female leg setation (Johnsson 2000). The new species has a 16 - segmented antennule, differing from S. adventicius, S. redactus and S. atypicus which have 17, 15 and 14 segments, respectively (Canário et al. 2012, 2019, Johnsson 2000). Consequently, the segmental homologies are different in the three species: Spongiopsyllus intermedius sp. nov. has the ancestral segments XXII free and, XXIII-XXVIII fused, S. redactus has XXII-XXVIII fused, S. atypicus has XXII-XXIII and XXIV-XXVIII fused, and S. adventicius has XXII and XXIII free, XXIV-XXVIII fused. Also, the new species shows the homologies of the basal segments of the antennule as II-III, IV-VI, VII, IX-XIII as in S. redactus, which is different from S. adventicius that has II, III-V, VI, VII- VIII, IX-XII and S. atypicus that has II, III-VIII, IX-XIII. (Canário et al. 2012, 2019, Johnsson 2000). Antennule segmentation patterns are built based on model proposed by Huys & Boxshall (1994). The number of setae and key segments such as the one with the aesthetasc provide the cues to trace the homologies and becomes strong characters used in diagnosis of genera and families, not only in Entomolepididae (Kim 2004, McKinnon 1988) but also in other families such as Asterocheridae (Conradi & Bandera 2011, Kim 2013) and Artotrogidae (Eiselt 1965, Kim 2016). S. intermedius sp. nov. has the endopod of the antenna 2 - segmented, as in S. redactus and S. atypicus however differing from S. adventicius, that is 3 - segmented (Canário et al. 2012, 2019; Johnsson 2000). Nevertheless, in the new species the distal endopodal segment shows 2 setae and row of setules along the outer margin while S. adventicius and S. redactus have 3 setae and a naked outer margin, and S atypicus has 4 setae and a margin ornamented with long setules (Canário et al. 2012, 2019; Johnsson 2000). The exopod of the antenna has 2 unequal apical setae in S. intermedius sp. nov. as in S. redactus, unlike S. adventicius that has 2 equal apical setae and S. atypicus that has a smooth distal seta and seven setules laterally (Canário et al. 2012, 2019; Johnsson 2000). The stylet in the new species tapers distally, similarly to S. adventicius but different from S. redactus that has subapical denticulated margin (Canário et al. 2012, Johnsson 2000). The inner lobe of the maxillule of S. intermeNEW dius sp. nov. is armed with 2 setae, instead of 3 as in S. adventicius and S. redactus, and 4 in S. atypicus (Canário et al. 2012, 2019; Johnsson 2000). The new species has the endopod of the maxilliped with armature formula 1,1,1, different from S. adventicius, S. atypicus and S. redactus that have 0,2,1; 2,0,1; and 2,1,1, respectively (Canário et al. 2012, 2019; Johnsson 2000). Spongiopsyllus intermedius sp. nov. also shows differences in the armature formula of the swimming legs. Coxa of leg 1 has no seta as in S. atypicus and unlike its other congeners that have an inner seta (Canário et al. 2012, 2019; Johnsson 2000). Basis of legs 3 and 4 with 1 - 0, while its congeners have no seta, except S. atypicus that has 1 - 0 on the basis of leg 4 (Canário et al. 2012, 2019; Johnsson 2000). Third endopodal segment of leg 1 with 6 setae altogether as in S. redactus, unlike S. adventicius and S. atypicus that has 5 setae (Canário et al. 2012, 2019; Johnsson 2000).	en	Borges, Camila, Farias, Amilcar, Mácola, Rosa, Neves, Elizabeth G., Son, Rodrigo Johns- (2021): A new Entomolepididae genus and a new species of Spongiopsyllus Johnsson, 2000 (Copepoda, Siphonostomatoida) and their association with Aplysina Nardo, 1834 (Porifera, Demospongiae) in Todos-os-Santos Bay, Bahia, Brazil.
