            <p>Male: Idiosoma length 430–470, width 260–330. Similar to female in most features except for those in the genital area and the plumose parambulacral setae on tarsus IV.</p>

Five pairs of sgs on genital sclerites, grouped 2:3. Spermatophorotype extending 17–24 μm beyond genital opening (Fig. 1 G).</p>
            <p>Deutonymph: Idiosoma length 320–425. Integument of posterior dorsal portion of idiosoma striated instead of maze-like, as found in adults. Two pairs of pgs on striated cuticle near genital plate. A pair of shorter setae on plate close to primordial GO. Underneath the genital plate, two pairs of genital acetabula found (Fig. 2 B). Leg chaetotaxy: Leg I, 1, 2, 8 (2S),8 (2S), 11 (4S), 5 (2S); leg II, 1, 4, 6, 8 (1S), 10 (2S, 1B),7; leg III, 2, 2, 5, 6, 8, 6; leg IV, 1, 2, 3, 4, 7–8, 5.

            <p> Etymology. The specific name refers to Omulu, an African god that is a member of the Candomble and the Umbanda pantheons, who is syncretically taken in Umbanda as Saint Lazarus. Hence, the name refers indirectly to the type locality, Lázaro Beach. It refers also to the fact that both Saint Lazarus and Omulu are depicted with skin pustules in their representations, and  Halacarus species have well-developed gland pores. </p>
            <p> Remarks.  Halacarus omului sp. nov. belongs to the  actenos species group, defined by the lacking of PD in both sexes, reduction or absence of OC, long apodemes on AE and PE, GA with rather uniform cerotegumental cover and two pairs of pgs adjacent to GO in the female, one pair (rarely two pairs) of pgs anterior to GA, one or two bipectinate setae on tibia II, claw shaft without tines, lateral claws often with pectinate accessory process (Bartsch, 2011). </p>
            <p> Currently, this group consists of 21 species:  H. actenos Trouessart, 1889 ,  H. griseus Bartsch, 1987 ,  H. longiunguis Police, 1909 ,  H. prolongatus Bartsch, 1996 , and  H. leptopus Bartsch, 2002 from the North Atlantic and the Mediterranean;  H. spongiphilus Kishida, 1927 ,  H. magniporus Krantz,1973 , and  H. mollis Sokolov, 1952 from the North Pacific;  H. higginsi Newell, 1984 , and  H. perditus Newell, 1984 from the Southeastern Pacific;  H. nitidus Bartsch, 1979 , and  H. socius Bartsch, 1992 from the Tropical Southern Pacific;  H. discophorus, Bartsch, 1993 ,  H. flavellus Bartsch, 1993 ,  H. fuscatus Bartsch, 1993 , and  H. multispinus Bartsch, 1981 from the Indian Ocean;  H. echinatus Newell, 1984 ,  H. falklandensis Newell, 1984 ,  H. hemispinosus Newell, 1984 ,  H. robustus Lohmann, 1907 , and  H. werthi Lohmann, 1907 from the Antarctic, Subantarctic and the adjacent sea (Bartsch, 2002, 2011). </p>
            <p> Among these species, only  H. actenos ,  H. leptopus ,  H. griseus ,  H. magniporus ,  H. prolongatus ,  H. longiunguis and  H. discophorus share the presence of ds-5 and gp-4, and adanal setae and gp-5, adjacent on the same sclerites with  H. omului sp. nov. (Bartsch, 2011). </p>

            <p>Species female male size size in relation to shape of posterior position gp-1 on</p>
            <p>length of AD AD AD</p>
            <p> Some taxonomic characters listed by Bartsch (2011) are scored for  Halacarus omului sp. nov. and the seven species mentioned above in Table 1.  Halacarus actenos differs from the present new species in having two setae on trochanter IV instead of one, by the absence of outlying setae on GA in the male, and by the gp-1 placed on the lateral edge of AD (Bartsch, 1980).  Halacarus leptopus is distinguishable form  H. omului by the absence of ventromedial bipectinate setae on genu II as well as a single such seta on tibiae II (Bartsch, 2002).  Halacarus discophorus differs from  H. omului by having a pair of sclerites among gp-4 and gp- 5 in the male, the triangular outline of posterior margin of AD, oval OC with the cornea, and four pairs of outlying pgs on GA in the male instead of a single pair of such setae (Bartsch, 1993).  Halacarus longiunguis differs from  H. omului in the lack of corneae, the presence of the accessory process on the lateral claws of tarsi III-IV, and only three ventral setae on tarsi IV (Bartsch, 2007).  Halacarus magniporus is discriminated from  H. omului by the protruded posterior margin of AD and the strong boat-shaped spine on P3 (Krantz, 1973).  Halacarus prolongatus differs from the present new species in the convex posterior margin of AD and the absence of OC and corneae in the ocular area (Bartsch, 1996). </p>
            <p> Newell (1947) assigned  H. actenos to Florida, USA, based on the study of a male, a female and three deutonymphs. Except for the deutonymph, all of the specimens had lost their distal leg segments before Newell’s examination.  Halacaridae species are known to be shared by Caribbean Sea and Brazilian coastline (e.g.  Copidognathus floridensis (Newell, 1947) ,  C. modestus Bartsch, 1984 and  C. longispinus Bartsch &amp; Iliffe, 1985 – Pepato &amp; Tiago, 2005). Nevertheless, similar to other  H. actenos specimens, Newell’s material has the trochanter chaetotaxy of 1, 1, 2, 2 (Bartsch, 2011), whereas the species described here has a 1, 1, 2, 1 trochanter formula. </p>

            <p>Gnathosoma length 130, width 77. Rostrum length 66, equal to 0.51 of gnathosoma length. Trito- and basirostral setae on rostrum (Fig. 3 C).</p>
            <p>Legs with striated cuticle (Fig. 4 A). Leg chaetotaxy as follows: Leg I, 1, 2, 8 (2S), 11 (2S), 13 (4S), 5 (2S); leg II, 1, 4, 6, 8 (1S), 10 (2S, 1B), 5; leg III, 2, 2, 4, 5, 8, 3; leg IV, 1, 2, 4, 5, 8, 3.

Length of telofemora, genua and tibiae of leg I, 122 μm, 111 μm, and 93 μm, respectively.</p>

            <p>Etymology. The name is dedicated to Dr. Antonio Todaro, who gave one of the individuals to the first author, and for his relevant contributions to the knowledge of meiofauna.</p>
            <p> Remarks.  Halacarus todaroi sp. nov. can be distinguished from congeners by the following set of characteristics: Absence of conspicuous sexual dimorphism concerning the extension of PD, which does not bear gp- 4 in either sex; corneae and gp-3 lacking on OC, although this plate is present and bears a pore canaliculus at its posterior corner; absence of a platelet posterior to OC or on PD, no pgs anterior to GA in neither female nor male; leg epicuticle striated. Some of the characteristics listed above are unclear from the original description of  Halacarus validus by Gimbel (1919) and the re-description by Newell (1984). However,  H. validus clearly differs from the species described here in the narrow AD posterior to gp-1, and ds-1 and gp-1 aligned. In  H. todaroi sp. nov. , AD is broader on its posterior portion, and ds-1 is posterior to gp-1. Other species that share some features with this new species are  Halacarus bisulcus Viets, 1927 and  Halacarus propiquus (Viets, 1940) .  Halacarus propiquus , however, is discernible from the new species by the presence of ventral setae on tarsi III and IV, and epicuticle on femora most likely punctuate instead of striated (Newell, 1984);  Halacarus bisulcus is also distinct from  H. todaroi sp. nov. in the presence of combs on lateral claws of tarsi II and III, and pgs ordered in a single ring around GO and three to four pairs of outlying setae in the male (Green &amp; Macquitty, 1987; Bartsch, 1980; Monniot, 1962), totaling 43 pgs according to Bartsch (1980, fig.19) instead of two pairs of outlying setae and 58 pgs ordered in two rings in  H. todaroi sp. nov.</p>
