FIGURES 29–32 in Metaperipatus inae sp. nov. (Onychophora: Peripatopsidae) from Chile with a novel ovarian type and dermal insemination
FIGURES 29–32. Spermatophores from body surface of different females in Metaperipatus inae sp. nov.. 29, Light micrograph of a spermatophore (arrow) attached to the ventral body surface. 30, SEM micrograph of a spermatophore (sp) from the dorsal body surface. 31–32, TEM micrographs of a sectioned spermatophore containing sperm (sz). 31, Overview. Note the close association of the spermatophore with the female's body surface. The arrow points to the region where the envelope is lacking and the lumen of the spermatophore directly borders the female's cuticle. 32, Detail of spermatophore envelope (en) closely associated with the female's cuticle (cu). Within the envelope, irregularly-shaped inclusions (in) are found. Br = sensory bristle, cu = cuticle, dp = dermal papilla, en = envelope of spermatophore, ep = epidermis, ex = exterior, in = irregular inclusions, le = walking legs (numbered), lu = lumen of spermatophore, nu = nuclei of epidermal cells, sp = spermatophore, sz = sperm cells, vm = ventral midline, vp = ventral pits (usually termed "ventral organs").
FIGURES 25–28 in Metaperipatus inae sp. nov. (Onychophora: Peripatopsidae) from Chile with a novel ovarian type and dermal insemination
FIGURES 25–28. Characteristics of ovary and associated structures in Metaperipatus blainvillei. Arrowheads indicate sperm cells. 25–26, 28, Azan-stained histological sections. 27, Nuclear staining of ovarian surface with DNA-selective dye (Hoechst, H33258); fluorescent micrograph. 25, Cross-section of ovary with a distinct sub-division into a sterile (st) and a germinal (ge) portion; dorsal is up. 26, Horizontal section of ovary with sperm cells associated with its surface. 27, Fluorescent micrograph showing nuclei of muscular cells (nu) from the ovarian surface interspersed with numerous filiform sperm heads (arrowheads). 28, Horizontal section of proximal portion of oviduct showing lumen of seminal receptacle (re) empty of sperm. Bl = basal lamina, ct = connective tissue, ge = germinal ovarian cell mass, he = hemocoel, lu = ovarian lumen, mu = musculature, nu = nuclei of muscular cells, oc = maturating oocytes, od = lumen of oviduct, re = lumen of seminal receptacle, st = sterile ovarian portion.
FIGURES 13–16 in Metaperipatus inae sp. nov. (Onychophora: Peripatopsidae) from Chile with a novel ovarian type and dermal insemination
FIGURES 13–16. Characteristics of legs in representatives of Metaperipatus (SEM micrographs). 13, 15, Metaperipatus inae sp. nov. 14, 16, M. blainvillei. 13–14, Ventral surface of fourth walking leg. In both species, there are four spinous footpads (numbered). The fourth pad is narrow, fragmented (and hardly recognized by light microscopy). The nephridial tubercle (ne) is placed in the middle of the third footpad. 15–16, Feet of adult specimens showing paired claws (cl) and distal foot papillae (arrows) that are duplicated in most cases. Circular insets represent feet in one day (M. inae sp. nov.), and two days old juveniles (M. blainvillei), respectively. Note that in juveniles, there are 3–4 distal papillae that are not duplicated or triplicated yet. Cl = claws, ft = foot, ne = nephridial tubercle.
FIGURE 1-2. 1 in Metaperipatus inae sp. nov. (Onychophora: Peripatopsidae) from Chile with a novel ovarian type and dermal insemination
FIGURE 1-2. 1. Map of Chilean provinces showing the type locality of Metaperipatus inae sp. nov. (black square) and the collecting site of specimens of M. blainvillei investigated in this study (black triangle). VIII = Region del Biobio, IX = Region de la Araucania, X = Region de los Lagos. 2. Comparison of body size in male and female specimens of Metaperipatus inae sp. nov. and M. blainvillei (drawn to scale after photographs of walking specimens in dorsal view).
FIGURES 20–24 in Metaperipatus inae sp. nov. (Onychophora: Peripatopsidae) from Chile with a novel ovarian type and dermal insemination
FIGURES 20–24. Characteristics of female genital tract in Metaperipatus inae sp. nov. (20, 24, SEM micrographs; 20: inset, TEM micrograph; 21–23, semi-thin sections). 20, Overview of ovary (ov) with associated structures. Distribution of accessory cell groups (ac) associated with oviducts is indicated by white brackets. Inset shows sperm cells (sz) from the ovarian tissue. 21, Cross-section of proximal ovarian portion with separate, crescent-shaped lumens (lu) on each side; dorsal is up. 22, Cross-section through the mid-ovarian portion with a narrow lumen separating the sterile (st) and germinal (ge) ovarian portions; dorsal is up. 23, Cross-section of oviduct with accessory cell groups (ac). Ac = accessory cell groups, ct = connective tissue, ge = germinal ovarian portion, lu = ovarian lumen, mc = muscular cells, oc = mature oocytes, od = oviduct, oe = inner epithelium of oviduct, ov = ovary, re = seminal receptacles (spermathecae), st = sterile ovarian cell layer, sz = sperm cells.
FIGURES 17–18 in Metaperipatus inae sp. nov. (Onychophora: Peripatopsidae) from Chile with a novel ovarian type and dermal insemination
FIGURES 17–18. Male and female genital tracts and associated structures in Metaperipatus inae sp. nov. (ink-drawings, anterior is up). 17, Male genital tract and associated glands in dorsal view. 18, Female genital tract and associated structures in ventral view. Note the seminal receptacles (arrowheads) near the proximal ovarian end. Ed = efferent duct, od = oviduct, ov = ovary, pg = male posterior accessory gland, te = testis, ug = female uterine gland, ut = paired uteri, vd = vas deferens, vs = seminal vesicle. FIGURE 19. Embryo of Metaperipatus inae sp. nov. with a large trophic vesicle (tv) in its neck-region (stage with 20–22 leg-bearing segments formed, camera lucida drawing). An = antenna, lb = anlagen of limbs, tv = trophic vesicle.
