            <p> Subfamily  MACROXENINAE Condé, 2008</p>
            <p>REMARKS</p>
            <p> Silvestri (1948) characterized three genera of  Polyxenidae bearing pseudoarticulated gnathochilarial sensilla:  Chilexenus ,  Macroxenodes and  Macroxenus . He distinguished  Chilexenus as provided with “3 sensillis bacilliformibus” on antennal article VI, as opposed to more than three in  Macroxenodes and  Macroxenus . Silvestri’s distinction between  Macroxenodes and  Macroxenus was based on the length and structure of the hooked trichomes of the caudal penicillus – characters that are no longer valid. Because of this and the addition of a fourth genus,  Afraustraloxenodes , bearing pseudoarticulated gnathochilarial sensilla, a new identification key is necessary. Recently these four genera have been combined in a subfamily  Macroxeninae Condé, 2008 (Condé &amp; Nguyen Duy-Jacquemin 2008). </p>
            <p>Other differences between the four genera</p>
            <p> Only in  Macroxenus are all the trichomes of the tergites oriented towards the telson (Fig.11B). In  Macroxenus , the ratio length/diameter of tergal trichomes is larger than in  Macroxenodes and  Afraustraloxenodes . In the only examined syntype of  Chilexenus , the length of trichomes seems similar to that of  Macroxenus . </p>
            <p> KEY TO THE GENERA OF THE SUBFAMILY  MACROXENINAE CONDÉ, 2008</p>

            <p> Genus  Chilexenus Silvestri, 1948</p>
            <p>REMARKS</p>
            <p> Silvestri (1903) described  Polyxenus rosendinus from specimens collected under bark of trees at San Rosendo, Chile, and later (Silvestri 1905: 722, 723, pl. 36 figs 38-41) added drawings of antennal articles VI to VIII, telotarsus, one external barbate and one internal hooked caudal trichome. In 1948 he created the genus  Chilexenus for this species. </p>

            <p>(Figs 2; 3)</p>
            <p> Polyxenus rosendinus Silvestri, 1903: 16 , 17. </p>
            <p> MATERIAL EXAMINED. — Chile. S. Rosendo, adult ♀ syntype, mounted on slide in Canada balsam (Museo civico di Storia Naturale di Genova). The label reads “  Polyxenus rosendinus Silv. Cotypus !!, S. Rosendo”. The thick microscope preparation does not allow a detailed observation of the ventral face. </p>
            <p>REVISED DESCRIPTION</p>
            <p>Coloration:Body and some trichomes pale yellowish; other trichomes varying from clear greyish to dark brown; pigmentation only present around ocelli.</p>
            <p>Measurements:Body length (without caudal penicillus) 2.70 mm; caudal penicillus length 0.90 mm. Length of tarsus II of 13th leg: 160 µm.</p>
            <p>Head: Eight ocelli on each side. Vertex with one pair of posterior tufts consisting of two rows: anterior row with 18 (right) and 19 (left), posterior row with 10 trichomes. The small distance between each tuft and the length of the trichomes as shown in Figure 3F.</p>
            <p>Length of antenna 0.50 mm; proportions of antennal articles as shown in Figure 3A; length of article VI twice its diameter. Antennal article VI with three, thick, dorsal sensilla basiconica: posterior sensillum slightly longer than the subequal anterior and median ones (Fig. 3C, E); one posterior sensillum coeloconicum. Antennal article VII with two dorsal sensilla basiconica: posterior one slightly shorter than anterior on left article (Fig. 3D); on right article, anterior sensillum is broken (Fig. 3B); one posterior sensillum coeloconicum. Three trichobothria of equal size, with cylindrical funiculi.</p>
            <p>Clypeo-labrum with12 setae along posterior margin and 12 lamellar teeth on anterior margin. External structure of labrum not visible. Lateral expansion of gnathochilarial palp with 18 pseudoarticulated sensilla on the right and 14 visible on the left; middle palpus with 20 (21? on left) visible (Fig. 3G).</p>
            <p>Trunk: Tergal trichomes arranged in two, long, oval tufts separated by a short space – sometimes occupied by two or more trichomes directed towards the telson (Figs 3H; 11A) – and one, uninterrupted, sinuous posterior row of trichomes directed towards the telson, running along posterior margin of tergite (Fig. 11A); about 146 trichomes on tergite VIII.</p>
            <p>Legs: (Fig. 3I). Trochanter and prefemur bearing one seta, coxa with one to three setae with slightly oval base. It is not possible to observe the small setae on femur and tibia. Second tarsus with a spine longer than the claw. Posterior lamellar process longer than claw; other process of telotarsus not visible.</p>
            <p>Telson: Type II (Condé 1970) characteristic of the subfamily: two latero-dorsal penicilli of hooked trichomes joined side by side; dorsal face of telson with a row of ten and 11 barbate trichomes a on each side of median plate (Fig. 3K); two subcircular groups composed of 10 barbate trichomes c, and one barbate antero-internal trichome b (Fig. 3K); on ventral face the usual subrectilinear row of barbate trichomes located at edge of penicillus of hooked trichomes is not visible. A large part of caudal penicillus is lacking; the left hooked trichomes have two hooks (Fig. 3J).</p>
            <p>REMARKS</p>
            <p> Tarsi II of  Chilexenus rosendinus each bear one spine (as in  Macroxenus ), hence  Chilexenus differs from  Macroxenodes and  Afraustraloxenodes , both of which have a seta rather than a spine on tarsus II.  Chilexenus differs from  Macroxenus in the different arrangement of the tergal trichomes: long oval lateral tufts separated by a short space and reduced anterior and posterior rows in  Chilexenus (Fig. 11A), long space between lateral tufts connected by an anterior row and a posterior row in  Macroxenus (Fig. 11B). </p>

            <p> Macroxenodes navassaensis n. sp.</p>
            <p>(Fig. 7)</p>
            <p>TYPE MATERIAL. — Greater Antilles. Navassa Island, Clench coll., I.1930., holotype ad. ♀ and paratype ad. ♀ very near to moulting, both mounted on slides (MNHN).</p>
            <p>ETYMOLOGY. — The name refers to the island where the type specimens were collected.</p>
            <p>DESCRIPTION OF FEMALE ADULTS</p>
            <p>Measurements: body length (without caudal penicillus): 3.10 mm (holotype) and 3.50 mm (paratype). Tarsus II length of 13th leg: 143 µm (holotype) and 146 µm (paratype).</p>
            <p>Head: Eight ocelli on each side. Vertex with one pair of posterior tufts, consisting of two rows: anterior row with 13-18, posterior row with 8 or 9 trichomes, the last in front of internal trichobothrium (Fig. 7E); the insertions of two last trichomes of posterior row are oriented perpendicularly to others (Fig. 7E). The distance between tufts is small.</p>
            <p>Proportions of antennal articles as shown in Figure 7A; length of article VI about twice its diameter. Antennal article VI with two groups of dorsal and postero-ventral sensilla: dorsal group composed of three thick sensilla basiconica: anterior a, intermediate i and posterior p (i being shorter than a and p), one posterior sensillum coeloconicum c and one trifid setiform sensillum s between a and i (Fig. 7C, D); postero-ventral group composed of two similar, thick sensilla basiconica, shorter than a and p. Antennal article VII with two subequal, thick, dorsal sensilla basiconica, one posterior sensillum coeloconicum and one trifid setiform sensillum between the two sensilla basiconica (Fig. 7B). Three trichobothria of equal size, with cylindrical funiculi (Fig. 7E).</p>
            <p>Labrum clothed with numerous small cuspidate papillae in addition to three rows (four towards lateral side) of spherical papillae (Fig. 7F). 6+6 (holotype) and 8+8 (Fig. 7F) lamellar teeth on anterior margin. Clypeo-labrum with 13 and 14 setae along posterior margin. In holotype, lateral expansions of gnathochilarium with 14 and 15 sensilla pseudoarticulated at apex (Fig. 7G) and middle palpus with 21 sensilla, comprising 12 long, pseudoarticulated sensilla and 9 short sensilla not articulated at apex; gnathochilarial sensilla cannot be counted in paratype.</p>
            <p>Trunk: trichomes are lacking; however, their orientation can be estimed thanks to their insertion. Except on collum and tergites IX and X, trichomes arranged in two lateral tufts with 16-33 trichomes connected by three trichomic rows: anterior row with 19-40 trichomes directed towards head; middle row with 7-21 trichomes and a sinuous posterior row with 42-74 trichomes directed towards telson; anterior and posterior rows uninterrupted. On some tergites the anterior and middle rows are slightly sinuous. Total number of tergal trichomes as follows: I (collum), 103 (holotype) or 123; II to VIII, 109 or 178; IX and X, 85 or 76. Lateral protuberance of tergite I with 5 (holotype) or 6 trichomes in a row.</p>
            <p>Legs: all articles of legs bearing sensory setae, first tarsus excepted. Setae on coxa, trochanter and prefemur with an oval base, provided with an apical process (Fig. 7J). Chaetotaxy as follows: coxae II to XII with 2 setae (1 seta in six cases, 3 setae in one case); trochanters with 1 seta; prefemora leg I to XIII with 1 seta and 1 or 2 small, trifid setae (Fig. 7H, I); almost all femora and tibiae with same small seta as prefemur. Second tarsus with a small seta as shown in Figure 7K. Telotarsus bearing an anterior process with a spinous projection longer than claw, two subequal latero-anterior and posterior spiniform processes; posterior lamellar process thickened and basally pleated (Fig. 7L).</p>
            <p>Four setae above the anal valve in paratype.</p>
            <p>Telson: dorsal face of telson with 13-16 barbate trichomes a; one trichome b inner to group of 19 trichomes c observed in paratype. Ventral face with a subrectilinear row of 14+14 barbate trichomes v in holotype and 13+ 15 in paratype (Fig. 6E), located on the edge of the insertions of fallen hooked trichomes.</p>
            <p>AFFINITIES</p>
            <p> This species is close to  Macroxenodes amazonicus Ishii, Nguyen Duy-Jacquemin &amp; Condé, 1999 . However, there are significant differences between them. The postero-ventral group of antennal sensilla of article VI has only two sensilla, as opposed to 4-7 in  M. amazonicus . Th ere are three anterior rows of spherical papillae on the labrum, whereas in  M. amazonicus there are only two. The new species has 15 sensilla at most on the lateral palp expansion, compared to 21-23 in  M. amazonicus . The median interruption of the anterior trichomic row of the tergites of  M. amazonicus is not present in the new species. </p>

            <p> This species is near to  Macroxenodes bartschi (Chamberlin, 1922) , as redescribed by Nguyen Duy-Jacquemin &amp; Condé (1984). The antennal sensilla of article VI are more numerous in the new species, always including two shorter and thicker sensilla basiconica on anterior part of the distal row; these two sensilla are not always present in  M. bartschi , sometimes there is only one shorter (Fig. 9I). The lateral palp expansion of the gnathochilarium is longer in  M. jahynyi n. sp. , with a maximum 28 sensilla, as opposed to 13 in  bartschi . There are only 3 anterior rows of spherical papillae on the labrum, whereas  M. bartschi has 4 or 5 rows. </p>
            <p> The two new species  M. navassaensis n. sp. and  M. jahynyi n. sp. are the fifth and sixth species included in genus  Macroxenodes . The others are  meinerti , the type species, from Venezuela (Caracas);  M. bartschi from the Florida Keys;  M. poecilus (Chamberlin, 1923) , redescribed by Condé &amp; Nguyen Duy-Jacquemin (1987), from Santa Inez Island, Gulf of California; and  M. amazonicus (Ishii et al. 1999) from Brazil, Amazonas, Ilha de Marchantaria and environs of Manaus. </p>

            <p> Monographis caingangensis Schubart, 1944: 331 , 332, figs 4, 5. </p>
            <p> TYPE MATERIAL. — Brazil. Oriental part of plateau de São Paulo, Mun. Pirassununga, Mogi-guassú, Sta. Rita, Pôrto Ferreira, syntypes (number of syntypes not mentionned in the original description) (  Musée de Zoologie de São Paulo; after Condé 1971). </p>
            <p>This species has been redescribed by Condé &amp; Massoud (1974) based on the following material: Brazil. Rio de Janeiro Prov., Restinga de Jacarapagua, 2 ad. ♂, 5 ad. ♀♀, 1 juvenile with 10 pairs of legs.</p>
            <p> The species  M. rubromarginatus , from North Africa, and  M. caingangensis , from South America, are very similar. The following material was examined to determine the morphological characters allowing their separation. </p>
            <p> MATERIAL EXAMINED. —  Macroxenus rubromarginatus : Maroc, Ifrane (alt. 1650 m), 2 ad. ♂♂ (MNHN) (Condé 1954). New material: Malte. Gozo, Kantura, 15.II.1992, leg. D. Mifsud, 1 ad. ♂ (ZMUC). — Portugal, Praia de Lourenço, Val de Parra, west of Albufeira, Algarve, coastal cliffs, 29.V.2004, A. P. Fowles coll., D. Kime leg., 1 ad. ♀ (MNHN). </p>
            <p> Macroxenus caingangensi s: Brazil. Rio Janeiro Province, Restinga de Jacarapagua, 13.V.1959, 1 ad. ♀, 1 ad. ♂ (MNHN). </p>

            <p>REMARKS</p>
            <p> Macroxenus rubromarginatus and  M. caingangensis are very similar. Nevertheless, they differ in the shape of the antennal basiconica sensilla (Fig. 10): these sensilla are thicker in  M. rubromarginatus (Fig. 10 A-E) than in  M. caingangensis (Fig. 10 F-H), i.e. the ratio length/diameter is higher in  M. caingangensis . </p>
