PORTERIA FIURA SP.NOV. FIGS 27–30 Zoobank registration: urn: lsid: zoobank. org:act: D7676422-0EB3-461E-B74D-9CB5A7C44B99. Types: Female holotype from Chile, X Región de los Lagos: Chiloé Province, Chiloé Island, Chiloé National Park, Sendero Tepual, 2.3 km NNE Cucao, S42º37.039’, W74º06.129’, elev. 1 m, January 16, 2013, C. Griswold, E. Morrill and D. Faber, ‘general collecting in bog forest dominated by Tepualia ’ deposited in MHNS (CASENT9055645). Male paratype from Chiloé Island, no specific locality, December 15–18, 1985, L.E. Peña, AMNH (CASENT9044672). Etymology: Named after La Fiura, an ugly, villainous woman who lives in the forest and clothes herself in moss; according to Chilote mythology, she seduces men and then drives them insane. Chiloé Island is the type locality, whose culture is rich in mythology. Sheet webs of P. fiura are often built on mossy substrates. Diagnosis: Males can be distinguished from others in the Albopunctata Grade by the round, stubby RTA (Figs 28B, 29B, C) and the small tooth-like DTA (Fig. 29D). The embolus base is wider (Fig. 29B) than that of P. albopunctata and the embolus tip more hook shaped (Fig. 29A); embolus tip much shorter than in P. eddardstarki. Females most closely resemble P. albopunctata but can be distinguished by the sclerotized median area being dilated anteriorly in P. fiura as well as the presence of a prominent scape (Figs 28E, 30A, B). Internally, the spermatheca stalks are situated much farther apart in P. fiura than P. albopunctata; Bennett’s gland pores large and conspicuous in dorsal view (Figs 28F, 30B). Description: Male: based on paratype CASENT9044672. Markings as in Figure 27 A-C, dorsum of abdomen with yellow anterolateral lines followed by two posterior spots and two pairs of median spots; sternum with pale centre surrounded by dark grey border.

Palp as in Figures 28 and 29, with four tibial apophyses: VTA triangular, flattened plate in ventral view, outline finger like in retrolateral view; RTA short and apex round, curved, directed ventrally; LRTA projected straight out of tibia, parallel to frontal plane. DTA small and tooth like; DTA and LRTA appear connected at fleshy base (Fig. 28D), like that of albopunctata. Tegulum without median concavity, outlined by dark sperm duct. Conductor originating on the midline of bulb, short and simple projection. Embolus base elongated, nearly the length of the bulb; embolus tip short, spiniform, curved like a hook to meet conductor. Paracymbium absent. Leg measurements (right): leg I 13.50 (3.75, 4.50, 3.25, 2.00); leg II 11.15 (3.15, 3.50, 2.85, 1.65); leg III 10.55 (2.85, 3.25, 3.00, 1.45); leg IV 13.80 (3.75, 4.30, 4.20, 1.55); palp 4.85 (1.80, 1.10, –, 1.95).

Base 2 joining the anterior margin of Base 1, somewhat crescent shaped; copulatory duct resting on anterior surface of Base 2. In total, the two receptacles look like one large, ovoid receptacle; scanning electron micrograph shows the division of the two bases in more detail (Fig. 30B). Leg measurements: leg I 12.17 (3.32, 4.20, 2.85, 1.80); leg II 10.25 (2.95, 3.40, 2.45, 1.45); leg III 9.70 (2.80, 3.00, 2.55, 1.35); leg IV 12.65 (3.45, 4.00, 3.55, 1.65); palp 3.92 (1.32, 1.32, –, 1.28). Variation: (N = 3). Total length 3.9–5.76. Carapace length 1.27–1.37 times width. Clypeus height 1.67–2.2 times AME diameter. ALE diameter 1.67–2.2 times AME diameter. Chelicera length 5–6.18 times clypeus height. Sternum length 1–1.04 times width. Femur I 1.08–1.26 times carapace length. Cheliceral promargin with four teeth and one denticle left, five teeth right. Distribution: Only known from Chiloé Island and on the mainland in Palena, 70 km south of Chaitén (Fig. 76C). Other material examined: X Región de los Lagos: Chiloé Province, same locality as holotype, nine females, CAS (CASENT9055645); Palena Province, 70 km S of Chaitén, elev. 500 m, January 16, 1986, N.I. Platnick, P.A. Goloboff, R.T. Schuh, ‘wet streambank’, one female, AMNH (CASENT9044706). Notes: Webs were found near ground level on fallen logs and low branches with retreats leading into the hollows of the trees, which were wet. Porteria was the predominant web along with austrochilids, orb weavers and linyphiids. Only females were collected on the 2013 expedition and were found in forest near the southern shore of Lago Huillinco; they were not found on the northern shore. In the southern sector of Chiloé National Park, they were found in high density along the Tepual Trail, and it is likely that males would have been found if we had been able to night collect. Male and female were tentatively matched by locality information. The only other species that has been found on Chiloé Island is P. bunnyana. Because this species has been collected with other males outside of the island, and never together with females of P. fiura, the unique male from Chiloé is hypothesized to be the same species as the female holotype. It is also noteworthy that one female specimen of P. fiura was found on the mainland, across the bay, south of El Chaitén; a lack of sampling in the area between Alerce Andino National Park and Torres del Paine could be obscuring the true range of this species, making it seem nearly endemic to Chiloé when this could merely be a sampling bias. This inadequate sampling applies to P. albopunctata as well, and possibly more undescribed species are awaiting discovery in southern Chile.

Epigyne as in Figures 41A and 42A, C, simple with two copulatory openings and median septum. Scape reduced to tiny nub visible in lateral and posterior views; difficult to see in ventral view except with SEM (Figs 41A, 42A). Vulva with long, coiled copulatory ducts leading into stalk of spermatheca adjacent to differentiated head of spermatheca. Pores present on head and stalk of spermatheca, pores of stalk obscured by copulatory ducts in dorsal view but visible in lateral view, see Figure 42D; Bennett’s gland pore not present in strict dorsal view, can be seen laterally on Base 1 just posterior to Base 2 (Fig. 41C).

PN Alerce Costero, Sendero Los Melíes, Sector Chaihuín, S39.95181°, W73.55325° (GPS ± 200 m), elev. 40 m, January 7, 2020, ‘Valdivian forest’, M.J. Ramírez, E. Soto, J. Wilson, D. Poy (MJR-loc-340), one female with embolus broken inserted in copulatory duct (MACN-Ar 41016, vchMJR-2454, photos 170056-170329). Notes: Porteria ajimayo densely populates the area outside of Concepción and are abundant in Nahuelbuta, though sympatric with P. contulmo and P. bunnyana. Two specimens from Valdivia suggest that the species has a wider distribution; this includes one female with a characteristically elongated male embolus stuck in the epigyne. Males and females are associated with high confidence based on collecting males and females on the same web as well as the highly elongated embolus and the equally long copulatory ducts, much longer than in any other species. A few webs of this species in MN Contulmo contained from one to three individuals of Sofanapis antillanca Platnick & Forster, 1989, but those kleptoparasite spiders were much more abundant in webs of Austrochilus forsteri Grismado, Lopardo & Platnick, 2003 (see Ramírez & Platnick, 1999).

PORTERIA EDDARDSTARKI SP.NOV. FIGS 1 A-D, 2E, 4B-D, 18–22, 31–36 Zoobank registration: urn: lsid: zoobank. org:act: 9FF1E8A2-602F-437A-9311-A57214E92821. Types: Holotype male and paratype female from Chile, V Región de Valparaíso, Zapallar, S32° 32.872’, W71° 27.171’, elev. 108 m, February 2, 2013, E. Morrill and C. Griswold, ‘general collecting in mixed native trees and plantation along arroyo’, CASENT9055699, deposited in MHNS. Paratype female from Quebrada el Tigre, 2.5 km E of Zapallar, S32° 33.086’, W71° 25.967’, elev. 357 m, February 12, 2011, M. Ramírez, E. Soto, J. Pizzaro, ‘bosque de boldo, belloto en quebrada’, one female (ex MACN-Ar27062), deposited in MHNS, and two females (MACN-Ar27062) deposited in MACN. Etymology: A patronym honouring the character Eddard Stark of the Game of Thrones series by George R.R. Martin. Eddard Stark was Lord Paramount of the North and, as this species is found only in the northern end of the geographical range of Porteria, we found it an appropriate way to recognize one of the few truly decent and respectable characters in the series. Diagnosis: Males can be distinguished from all species in the Albopunctata Grade except P. ajimayo by the lack of a DTA (Figs 32E, 34B); it can be distinguished from P. ajimayo by the much shorter embolus tip (Fig. 32D), and the shape and orientation of the embolus base and conductor (Figs 32D, 33A, B, 34A, D). Females can be distinguished by their heavily sclerotized and darkened epigyne with two conspicuous posterior lobes (Fig. 35 A-C) and relatively large median scape (Fig. 36A, D). Internally the copulatory ducts are much longer than other species of the Albopunctata Grade, each duct forming one anterior loop (Figs 35D, 36B). Only known from Region V and the north. Description: Male: based on CASENT9055699, from Zapallar. Markings as in Figure 31 A-C, anterolateral lines on dorsum of abdomen reduced or absent; median markings in pairs and series of chevrons posteriorly; sternum uniform in colour. Total length 5.28. Carapace length 1.43 times width. Clypeus height 1.80 times AME diameter. ALE diameter 1.40 times AME diameter. Chelicera length 11 times clypeus height.

Notes: Two different habitat types are occupied by the inland and coastal populations. The inland spiders live in desert hills and construct expansive sheet webs in low lying shrubs and on sandy banks where the funnelled retreat runs into the sand. The coastal populations were found in forested gulches with much higher moisture levels and also build large sheets in leaf litter, and in some cases, on the sides of rock outcrops with funnels disappearing into crevices. Due to the allopatric distribution and distinctive large size of this species, as well as collections of male and females together, male and female association is with high confidence and is supported in the molecular analysis. These data also indicate that inland and coastal populations form two distinct clades, but no morphological characters have discovered to differentiate the two populations., Published as part of Morrill, Elizabeth, Crews, Sarah, Esposito, Lauren, Ramírez, Martín J. & Griswold, Charles, 2023, A revision of the genus Porteria and the phylogeny and biogeography of Porteriinae (Araneae: Desidae), pp. 368-461 in Zoological Journal of the Linnean Society 198 (2) on pages 406-413, DOI: 10.1093/zoolinnean/zlac093, http://zenodo.org/record/8007404

Notes: Females of this species are difficult if not impossible to differentiate from those of P. contulmo, and there could be more cryptic species within this group. Males and females in Pucón have been collected together and have been more frequently collected together than P. bunnyana females and males of other species. When P. bunnyana females have been collected with P. correcaminos, a sympatric species, it has often been by flight intercepts or other long term, broadscale collecting methods, which may blur differences in temporal occurrence., Published as part of Morrill, Elizabeth, Crews, Sarah, Esposito, Lauren, Ramírez, Martín J. & Griswold, Charles, 2023, A revision of the genus Porteria and the phylogeny and biogeography of Porteriinae (Araneae: Desidae), pp. 368-461 in Zoological Journal of the Linnean Society 198 (2) on pages 421-426, DOI: 10.1093/zoolinnean/zlac093, http://zenodo.org/record/8007404

PORTERIA CORRECAMINOS SP.NOV. FIGS 7, 16A, B, D, F, 17 A-C, 60–64 Zoobank registration: urn: lsid: zoobank. org:act: 2F980E92-45F0-4E0E-8BB8-6FBC9B55F24E. Types: Holotype male, 13 paratype males and 12 paratype females from Chile, X Región de los Lagos, Llanquihue Province, Vicente Pérez Rosales National Park, January 2–28, 1997, (FMHD97-8), deposited in FMHD. Etymology: Correcaminos is Spanish for road runner, this species is so named because it is lightning fast on their webs and can be frustrating to collect. A noun in apposition. Diagnosis: Males of this species can be identified by the anvil-shaped DTA (in lateral view, Figs 61A, D, 62C, 63C) and swollen RTA with a large tooth-like projection (Figs 61E, 62C, D, 63D). This species can be distinguished from P. contulmo by the length of the DTA’s pointed apex (Figs 62D, 63D), longer and more attenuate in P. contulmo (Figs 67D, 68F); RTA appears closer to 90° from tibia in P. correcaminos (Figs 61B, E, 62C). Female with large epigyne (Figs 61F, 64A, C), atrium with an ‘M’-shaped margin like P. bunnyana (Fig. 48A) but with large, fleshy bulge protruded from atrium just posterior to scape (Fig. 64C); scape much smaller than in P. bunnyana and finger like (Fig. 64C). Large, fleshy posterior shelf extended into the atrium and out laterally, forming two elongated lobes that curve to meet the lateral margins of the atrium, forming a deep groove (Figs 61F, 64D, F); this deep fold is absent in P. bunnyana (Fig. 48B) and P. ariasbohartae (Fig. 71G, H).

Notes: Males of this species were not collected with females on the 2013 trip, likely due to a lack of night collecting at the targeted localities. Females have been collected with males though other species occur in sympatry. However, DNA analysis supports this male-female association (‘ correcaminos ’ in Fig. 73).

PORTERIA SIMON, 1904 Porteria Simon, 1904: 109 (type species Porteria albopunctata Simon, 1904, by monotypy). Diagnosis: Porteria species resemble their relative porteriines Nanocambridgea, Cambridgea and Corasoides in the remarkable narrowing of the ALS piriform gland spigot field (Fig. 5), the cymbium highly elongated beyond the bulb and the lack of a median apophysis, but it differs from all of these by the presence of a thin tibial apophysis (LRTA) arising near the base of the RTA on the male palpal tibia (Fig. 68), and a line of five to six stout setae just posterior to the ALS spinning field of both sexes (Fig. 5B). Among the Chilean fauna, Porteria species are the only marronoids with the narrow tip of the cymbium extending 1.5 to 5 times the length of the copulatory bulb. The epigyne has a minute to large anterior median scape (Figs 30C, 53A), and the spermatheca is bilobed, here referred to as base 1 and base 2 of the spermatheca. All species except P. eddardstarki have distinctive dorsal abdominal markings consisting of white to yellow anterolateral lines and median spots (Fig. 13). Porteria are like Corasoides but differ from Nanocambridgea and Cambridgea by walking on the upper surface of the sheet web instead of hanging from it. Description: Small to medium sized spiders with total length 3.9–9.1. Characteristic markings as follows (Figs 13, 14): carapace pale yellow to orange-brown with darkened lateral margins with three distinct, sometimes diffuse grey lines radiating outward from thoracic furrow; grey lines outline cephalic region along cervical groove. Black pigment surrounding each eye, connecting the lateral eyes and AMEs. Sternum with dark grey margins enclosing a pale yellow median region. Paler region varies in size and shape from large oval to small sliver: this contrast is faded in older specimens. Endites, labium and chelicerae orange-brown in colour; endites and labium lighter in colour toward tips. Coxae pale yellow with grey distal margins. Legs with alternating yellow and grey rings that vary from distinct to subtle, more obvious in fresh specimens. Dorsum of abdomen dark grey with white to golden yellow, longitudinal anterolateral lines converging anteriorly; lines half the length of abdomen, becoming indistinct spots posteriorly. Fainter paired median spots sometimes present. Porteria eddardstarki with anterolateral lines reduced and dark grey dorsum mottled with golden yellow (see species descriptions). Venter yellow to grey, with median grey rectangle and two dark grey semi-circles anterior to spinnerets. Epigyne outlined with grey trapezoid with two yellow spots; trapezoid also present in males between book lungs. Spinnerets orange-brown to grey. Carapace length 1.20–1.51 times carapace width, height 0.23–0.61 times width. Thoracic fovea 0.07–0.31 times carapace length, slit like and moderately deep. Posterior eye row (PER) straight when viewed from above; anterior eye row (AER) slightly procurved from anterior view (Fig. 15B). Anterior lateral eyes (ALE) diameter 1.29– 2.00 times anterior median eyes (AME). Clypeus height 1.67–2.83 times diameter of AME. Posterior median eyes (PME) about equal to posterior lateral eyes (PLE) diameter. Secondary eyes with canoeshaped tapetum (Fig. 15B). Sternum length 0.94–1.46 times width; labium as long as wide. Chelicera length 5.20–16.5 times clypeus height. Chelicera vertical in most species, porrect in P. eddardstarki males (Fig. 31). Cheliceral fang margin with escort setae, rake setae and whisker setae (see Ramírez, 2014). Retromargin of chelicera with two teeth separated far apart; promargin typically with five teeth and one to three small denticles (Fig. 16C); see variations in species descriptions. Fangs constricted or not; constriction highly exaggerated in P. albopunctata males (Fig. 23D). Male femur I 1.23–1.63 times carapace length; female femur I 1.03–1.34 times carapace le ngth. L eg formulaty pically 4123, sometimes 1423; leg I and IV about equal in total length. General spination as follows (based on P. eddardstarki, Figs 18–21; see spine map Fig. 22): Male: palp: femur d1-1-2, patella d1-1, tarsus r0-0-1, v0-0-1; leg I: femur d1-1-1(p)-1(p)-2, patella d1-1, tibia d1(r)-0-0, v0-2-2, metatarsus v2-2-3; leg II: femur d1-3-2-2, patella d1-1, tibia d1(r)-0-0, v0-0-2, metatarsus p0-1-0-1, r0-0-1, v1(r)-2-2; leg III: femur d1-3-1(r)-2, patella d1-1, tibia d1(r)-1-0, p0-1-1-0, r0-0-1-0, v0-0-2, metatarsus d1(r)-2-2, p1-0-0, v2-2-3; leg IV: femur d1-1-1(r)-1(r)-2, patella d1-1, tibia d1(r)- 1-1, p1-1-0, r0-1-1-0, v0-1(r)-2, metatarsus d1(r)-1-1, p1-1-1, r0-1-0-1, v2-2-2, tarsus r0-1.

Spinnerets of males as follows: ALS with spinning field similarly shaped to that of females, with piriform gland spigots, numerous piriform tartipores, and a single MAP gland spigot with adjacent MAP nubbin (Nu) and tartipore. PMS with aciniform gland spigots. PLS with aciniform gland spigots. Colulus (Cl) of both sexes linguiform with setae on anterior half (Fig. 5F). Tracheal system (Fig. 16D): spiracle just anteriad of colulus, less than colulus’ length away; lateral tracheae unbranched, medians branched, all tracheae limited to opisthosoma. Male palp with cymbium greatly elongated distal to bulb (Figs 25E, 28E, 32E, 38E, 45E, 50E, 55D, 58D, 61E, 66D, 71E); cymbium 2.21–5.94 times length of bulb. Prominent bulb structures include tegulum with median concavity present or absent, fleshy conductor, and a slender embolus of varying lengths; embolus base varies in shape and is diagnostic in species identification. Tibia of male palp with three to four apophyses: stout, acuminate RTA; needle-like LRTA positioned mesad to RTA; dark, flattened ventral apophysis (VTA); dorsal tibial apophysis (DTA) present or absent, shape diagnostic for some species. Knob-like paracymbium (PC) on retroapical side of alveolus present or absent. Palpal bulb (Fig. 68B, D) without median apophysis; embolus (E) with slender tip converging onto large, fleshy conductor (C). Epigyne and vulva highly variable; heavily sclerotized or fleshy, with little to no sclerotization; median scape (Sc) present in all species but varies in form and size. Epigyne usually partially obscured by a covering of long setae. Vulva with short to long copulatory ducts (CD), spermathecal head (HS) differentiated or not from rest of spermathecae; pores present on head and spermathecal stalk (SS); stalk leads to base 1 and base 2 of the spermatheca. Base 1 of spermatheca can be distinguished from base 2 by the presence of the Bennett’s gland (BG) and the attachment of the fertilization duct (FD). Females of the bunnyana species group with a central atrium, with ventral wall flexible, wrinkled (Fig. 64D, F), and a pair of invaginations on the posterior margin of the epigyne (Fig. 64A, B; uncertain where they lead). Biology: The biology that follows is mostly known from observations made in the field during a January 2013 excursion by the authors Charles Griswold, Elizabeth Morrill and colleagues Hannah Wood, David Faber and Luke Macaulay, complemented with data from several excursions by Martín Ramírez. Porteria are sheet web builders that construct webs in low lying vegetation, fallen logs and leaf litter (Fig. 2). They are abundant with many individuals residing in a small area. The spiders walk or run on top of the sheet. The web itself is made of a strong, finely woven sheet; above this is a loosely woven system of knock-down threads that probably help prevent prey from escaping, and a mess of supporting lines to secure the sheet to the substrate. At one edge of the sheet lies the funnelled retreat that leads into leaf litter, hollow logs or other crevices. Porteria were often found near austrochilids and seem to prefer a similar habitat, though austrochilid webs are generally much higher off the ground than those of Porteria. The web of Porteria can be distinguished from often sympatric linyphiid spiders by the sheen and glittering appearance of the silk in the sunlight; linyphiid webs often appear softer and duller; Porteria ’s sheet is stronger to the touch than those of linyphiids. Porteria sheets are not found on artificial or man-made substrates. The spiders often hide in the funnel retreats during the day or when their web has been disturbed. At night, the spiders stand just outside of the funnel and are much more active pursuing prey. Many spiders were successfully collected by mimicking small prey vibrations on the sheet (either by aspirating small insects or using small twigs) to draw the spider out of the retreat and then a spoon was used to cut off access back into the retreat; the spiders were fast, and if they were able to retreat into the funnel, they were often lost in the great expanse of leaf litter and other debris. It is expected that once males reach maturity, they discontinue web building and search for females. Adult males were often found in penultimate and adult female webs at night. When males did make small movements towards the female, she would often move underneath the web nearby and hang upside down. We know nothing of the eggs or maternal care of Porteria. Composition: Twelve species, including the type species P. albopunctata Simon 1904, and 11 species newly described here: P. ajimayo, P. alopobre, P. ariasbohartae, P. bunnyana, P. contulmo, P. correcaminos, P. eddardstarki, P. faberi, P. fiura, P. misbianka and P. torobayo. Distribution: Chile, ranging from IV Región de Coquimbo at the northern end of their range to Punta Arenas in Magallanes Province at the southern end of their range (Fig. 76 A-F). Phylogenetics: Like the other porteriines Nanocambridgea, Cambridgea and Corasoides, Porteria have the remarkable narrowing of the ALS piriform gland spigot field (Fig. 5), the cymbium highly elongated beyond the bulb and lack a median apophysis, but Porteria differ from all of these by the synapomorphies of the presence of a thin tibial apophysis (LRTA) arising near the base of the RTA on the male palpal tibia (Fig. 68) and a line of five to six stout setae just posterior to the ALS spinning field of both sexes (Fig. 5B)., Published as part of Morrill, Elizabeth, Crews, Sarah, Esposito, Lauren, Ramírez, Martín J. & Griswold, Charles, 2023, A revision of the genus Porteria and the phylogeny and biogeography of Porteriinae (Araneae: Desidae), pp. 368-461 in Zoological Journal of the Linnean Society 198 (2) on pages 377-395, DOI: 10.1093/zoolinnean/zlac093, http://zenodo.org/record/8007404, {"references":["Simon E. 1904.

PORTERIA MISBIANKA SP.NOV. FIG. 43 Zoobank registration: urn: lsid: zoobank. org:act: F81ABF78-1D6E-4D1C-87B6-9FCB0645118C. Types: Female holotype from modified forest under rocks in Chile, VIII Región del Bío-Bío, Concepción Province, Estero Nonguén, elev. 90 m [-36.8766 – 72.9913 º] collected Nov 16, 1981 by N. Platnick and R.T. Schuh, collected in ‘modified forest under rocks’, deposited in AMNH (CASENT9044700). Etymology: Derived from ‘Miss Bianca,’ the leading lady mouse in the Disney movie ‘The Rescuers.’ This species is so named due to the resemblance of the epigyne to the face of this mouse. A noun in apposition. Diagnosis: This species can be distinguished from other species by the simple topography of the epigyne, only two slit-like copulatory openings and small median scape (Fig. 43D, E); the ‘peak-forming’ copulatory ducts seen in ventral view through the cuticle (Fig. 43E) are also distinctive (and distinguish it from P. ajimayo). Internally, the ‘S’-shaped copulatory ducts are diagnostic (Fig. 43F). Porteria ajimayo has much longer copulatory ducts forming a complicated maze of loops (Figs 41B, 42B, D). Description: Female: based on holotype. Markings as in Figure 43 A-C, white anterolateral lines, two adjacent posterior bands and pair of median spots. Total length 6.36. Carapace length 1.40 times width. Clypeus height 2 times AME diameter. ALE diameter 1.78 times AME diameter. Chelicera length 6.67 times clypeus height. Sternum length 1.12 times width. Cheliceral promargin with five teeth and one denticle. Leg formula not assessed, because many legs are missing from specimen, both leg IVs and either a right leg II or III, no palps present. Leg spination as follows: leg I: femur d1(r)-1-1(p)-1(r)-2-1(p)-2, patella d1-1, tibia d1(r), p0-1-1-0, r0-1-0-0, v2-2-2, metatarsus p0-1-1, r0-1-2, v2-2-2; unknown right leg II or III: right leg IV: femur d1-1-1(p)-1(r)-2, patella d1-1, tibia d1(r)- 0-1-0, p0-1-1-0, r0-1-1-0, v1(p)-1-2, metatarsus d2-0-0, p0-1-1, r0-1-1-2, v1(p)-1(p)-2, tarsus r0-1. Epigyne as in Figure 43D, E, a lightly sclerotized plate, tapering posterior to epigastric furrow; two sclerotized slits just anterior of epigastric furrow are the copulatory openings; between these openings is the scape which tapers posteriorly and originates just anterior to the copulatory openings (Fig. 43D); much of the anterior internal structures can be seen through the cuticle, most obvious the copulatory ducts converging to a peak with each other and connecting to a large circular receptacle (Fig. 43E). Vulva as in Figure 43F, consisting of a pair of long, ‘S’-shaped copulatory ducts running adjacent and parallel to each other initially in the middle of the vulva curving upwards and laterally to meet the ventral surface of the spermatheca stalk, adjacent to the spermatheca head. The stalk runs down the lateral side of the spermathecal bases and the head is located on the anterolateral surface of the stalk. Bases of spermatheca similar to those of P. ajimayo, but copulatory ducts much longer on P. ajimayo. Right and left Base 1 are contiguous, no gap; the connection between Base 1 and Base 2 is obscured by ducts, but Base 2 appears attached to the anterior margin of Base 1, projecting out laterally behind (ventral) the stalk. Because this is the only specimen, there was no SEM preparation of the vulva, so the Bennett’s gland pore was not explicitly seen but is likely on the lateral surface of Base 1 at the transition between Base 1 and 2 based on the morphology of other species. Pores are visible on the head of the spermatheca and can likely be found on the stalk as well, but they are not visible with a stereomicroscope. Fertilization ducts transparent, leaf like, attached to posterolateral corner of Base 1. Leg measurements: leg I NA; leg II NA; leg III 7.98 (2.35, 2.61, 1.88, 1.14); leg IV 9.65 (2.68, 3.02, 2.68, 1.27); palp NA. Distribution: Known only from the type locality at Estero Nonguén, Concepción (Fig. 76C). Other material examined: None. Notes: The type and only known specimen of this species was searched for at Parque Pedro del Rio Zañarto and in the nearby Cerro Caracol, a tree-lined hill and popular urban park, but Porteria was not found there during the 2013 trip. For future expeditions, the Reserva Nacional Nonguén seems like a promising place to look for P. misbianka, which is close to the type locality, contains one of the last remnants of deciduous forest in the area and is home to various rare and endemic species (http://www.conaf.cl/parques/reservanacional-nonguen/). THE BUNNYANA SPECIES GROUP A monophyletic group (Figs 73, 74) defined by the genitalic synapomorphies of both males and females (discussed below), easily distinguished from the second species group, the Albopunctata Grade. Model figures for the Bunnyana species group with genitalic parts labelled are Figure 64 (female genitalia of P. correcaminos) and Figure 68 (male genitalia of P. contulmo). Females have a deep median atrium in which the copulatory openings are sunken, with a wrinkled, flexible ventral wall, and two posterior invaginations of the epigynal cuticle near the epigastric fold (Figs 53A, 64A, B, 69A). Females in this species group are much more difficult to differentiate from one another, and many are sympatric, making it even more difficult to separate species. In males, the palp has a paracymbium in the form of a small, round projection on the retrolateral side of the cymbium near the distal edge of the bulb (Figs 46C, 47C, 51C, 67C). The LRTA is bent at the middle, so the apex is projecting out of the frontal plane, almost appearing as a 90° angle in lateral view (Figs 46C, 56C, 62C). The embolus base is also more shield like in the bunnyana group (Figs 46A, 56B). Included neae species: Porteria alopobre, Porteria ariasbohartae, Porteria bunnyana, Porteria contulmo, Porteria correcaminos, Porteria faberi, Porteria torobayo.
