453789956CE75BCFAD274D9457C2D939.taxon	description	Description. Baena (type) population: Adult. Slender (a = 40 – 49) nematodes of small to medium size, 0.82 – 1.04 mm long. Body cylindrical, tapering towards both extremities. Upon fixation, habitus regularly curved ventrad, often adopting an open C shape. Cuticle dorylaimid, two-layered, thin, ca 1 µm thick throughout the entire body, outer layer bearing very fine transverse striation, better observable with SEM. Lateral chord 6.0 – 6.5 µm wide, occupying less than one-third (26 – 31 %) of mid-body diameter, bearing abundant granular gland bodies. Body pores abundant, appearing as (SEM observations, Fig. 4 J) short longitudinal slits. Lip region cap-like, offset by constriction, 1.7 – 2.0 times as wide as high and up to one-third (28 – 33 %) of body diameter at neck base, with a well-differentiated, refractive perioral disc; SEM observations: lips amalgamated, their inner region visibly offset and somewhat expanded, forming a small sucker-like perioral disc 4.0 – 4.5 µm wide and divided into six triangular sectors by the existence of six radial, interlabial incisures running from the oral aperture to the margin of the disc, labial and cephalic papillae low, but comparatively large and distinct, button-like, with a coarse pore at their center. Amphid fovea cup-like, its opening 6.0 – 6.5 µm wide, occupying the entire diameter of lip region. Cheilostom 6.0 – 6.5 µm long, almost cylindrical, thin-walled, with circumoral sclerotized pieces at its anterior end. Odontostyle typical dorylaimid but small, almost equal (0.9 – 1.0 times) to lip region diameter long, occupying 0.56 – 0.66 % of body length, ca 5.0 times as long as wide, with short aperture ca one-fifth of its length. Guiding ring simple, often inconspicuous. Odontophore visibly flanged, 1.8 – 2.0 times the odontostyle. Pharynx consisting of a slender and weakly muscular anterior region suddenly enlarging into the basal expansion 10 – 16 times as long as wide, 5.3 – 8.1 times longer than body diameter at neck base, occupying more than half (53 – 59 %) of the total neck length, and surrounded by a distinct spiral muscular sheath, its gland nuclei and outlets obscure in the specimens examined, some specimens bearing a few refractive globules at its anterior end. Cardia small and rounded, 9 – 11 µm long. Female. Genital system diovarian, with both branches equally and variably developed, the anterior 74 – 122 µm or 8 – 12 % of the total body length, the posterior 87 – 108 µm or 9 – 11 %. Ovaries comparatively small, often not reaching the oviduct-uterus junction, 31 – 61 µm the anterior and 36 – 48 µm the posterior, with oocytes first arranged in two or more rows and then in one single one. Oviduct 42 – 65 µm or 2.1 – 3.3 body diameters long, consisting of a long and slender distal region made of prismatic cells and a developed proximal pars dilatata with visible lumen. A distinct sphincter present between oviduct and uterus. Uterus a simple tube-like structure 27 – 38 µm or 1.4 – 1.9 body diameters long. Vagina extending inwards 8.0 – 9.5 µm, to less than one-half (38 – 45 %) of body diameter: pars proximalis 5.0 – 6.0 × 6.0 – 6.5, with almost straight to somewhat convergent walls that are encircled by weak musculature, pars distalis 3.0 µm long. Vulva a longitudinal slit ca 2 µm long. Prerectum 6.2 – 6.6, rectum 1.2 – 1.3 anal body diameters long. Tail convex conoid to slightly subcylindrical. Male. Genital system diorchic, with opposite testes. In addition to the adcloacal pair, situated at 4 – 5 µm from the cloacal aperture, there invariably are four very simple (non-mammiform but a low pore-like structure, Fig. 4 I) ventromedian supplements arranged in a more posterior pair located at 38 – 41 µm from the ad-cloacal pair and two more anterior and spaced ones at 23 – 25 µm from the posterior pair. Spicules dorylaimid, strongly curved ventrad, 3.7 – 4.1 times as long as wide and 1.4 – 1.7 times longer than body diameter: head 3.0 – 3.5 µm long, up to one-sixth (13 – 15 %) of spicule length, and almost as long as wide; median piece occupying less than one-third (15 – 31 %) of maximum width; ventral hump and hollow very prominent, the former located at 7.5 – 9.0 µm from the anterior end; curvature 127 – 128 °. Lateral guiding piece simple, 6 µm long. Tail somewhat less convex conoid than that of female.	en	García-Ruiz, Miriam, Abolafia, Joaquín, Peña-Santiago, Reyes (2025): Retrieval of the genus Capitellus Siddiqi, 1983, with description of C. caramborum sp. nov.
