Simlops cachorro Ruiz View in CoL , new species Figures 3 View Figs , 9 View Figs , 177–198 View Figs View Figs View Figs , 285 View Figs , 310, 311 View Figs , 327 View Figs

TYPES: Male holotype and female paratype from Quebradón El Ayo , La Pedrera, Amazonas, Colombia (1 ° 019210 N 69 ° 359130W), Feb. 01, 2002, J. Pinzon, ( ICN PBI_OON 40569; ICN PBI_OON 40576) .

ETYMOLOGY: The specific name is a reference to the Cabeça do Cachorro (‘‘dog’s head’’) region, in extreme northwestern Brazil, along the Colombia border, from where the records of this species come from. (The region is so named because a drawing of the borders of Brazil and neighbor countries resembles a dog’s head.)

DIAGNOSIS: Males of Simlops cachorro differ from those of S. jamesbondi and S. platnicki by the complex, loosely attached conductor (figs. 310, 311); females can be recognized by the thin anteromedian rod, without apical enlargement (fig. 327).

MALE (PBI_OON 40569, figs. 3, 9, 177– 190, 285, 310, 311): Total length 1.79. Carapace dark red-brown, sternum and mouthparts orange-brown; legs orange-brown, without color pattern; abdomen soft portions pale white; abdominal scuta orange-brown. Sternal microsculpture medially and in furrows. Endites retrolateral projection stout, distally bulging, sculptured, with sharply pointed triangular process directed prolaterally; prolateral and median processes geminated (as seen in collapsed pieces for SEM, figs. 185, 186), prolateral process flat, blunt, curved retrolaterally (fig. 285). Postepigastric scutum almost semicircular, covering about 3/4 of abdominal length. Leg spination, tibiae: I p1-1-0; r1-1-0. Palp: embolus bent prolaterally, stout, about half as long as cymbium, with widened, sculptured subtriangular tip; conductor complex, loosely attached to base of embolus, but otherwise heavily sclerotized, with a distal, narrow branch and a proximal, flattened branch (figs. 182–184, 187–190, 310, 311).

FEMALE (PBI_OON 40570, figs. 191– 198, 327): Total length 2.06. Dorsal scutum absent. Leg spination, tibiae: I p1-1-0; r1-1-0. Epigastric furrow medially straight, medially sclerotized, without median notch, connected laterally to anterior spiracles; postepigastric scutum with anterior margin sclerotized, not extending beyond groove connecting posteri- or spiracles, not enlarged laterally around posterior spiracles, without discrete lateral sclerotizations. Genitalia with thin posteromedian rod, anterior end pointed, without enlargement; transverse bar thick, straight,

with large rectangular plate close to epigastric furrow and short, thick, parallel lateral apodemes (figs. 198, 327).

ETYMOLOGY: The specific name is a patronym in honor of Norman I. Platnick (AMNH), the first one to recognize this species as a ‘‘highly autapomorphic Niarchos - like species.’’

DIAGNOSIS: Males of Simlops platnicki differ from those of S. jamesbondi and S. cachorro by the extremely long retroapical process at the endites (fig. 286) and by the pointed conductor, inserted at the middle of the embolus (figs. 312, 313). Females can be readily recognized by the short, robust, bushshaped anteromedian rod, with wide triangular apex and by the thick transverse bar (fig. 328).

MALE (PBI_OON_0040500, figs. 4, 10– 12, 199–216, 286, 312, 313): Total length 1.63. Carapace and sternum pale orange, mouthparts orange-brown, legs pale orange, without color pattern; abdomen soft portions yellow, abdominal scuta pale orange. Sternal microsculpture only in furrows. Endites with retrolateral process extremely developed, tubular, with blunt, sculptured apices and apical projection directed prolaterally; prolateral process thin, gently curved retrolaterally; prolateral and median processes geminated; median process protruded (figs. 207–210, 286). Postepigastric scutum almost rectangular, covering about 2/3 of abdominal length. Leg spination, tibiae: IV p0-0-1. Palp: embolus gently curved medially, with small retromedian expansion and rounded, retroapical lamellar prong; conductor heavily sclerotized, hook shaped, originating at the embolar body (figs. 204–206, 213–216, 312, 313).

FEMALE (PBI_OON 40501, figs. 5, 6, 27, 28, 217–228, 328): Total length 1.84. Dorsal scutum absent. Leg spination, tibiae: I v2-2-1r; II v2-2-0; III p0-1-0; IV p1-1-0; metatarsi: I v2-2-0. Epigastric furrow medially straight, medially sclerotized, without median notch, not connected laterally to anterior spiracles; postepigastric scutum with anterior margin sclerotized, not extending beyond groove connecting posterior spiracles, not enlarged laterally around posterior spiracles, without discrete lateral sclerotizations. Genitalia with short, robust posteromedian rod, anterior end large, triangular; transverse bar thick, straight, with large rectangular plate, bearing anterior porous area of circular pits, and long, thick, parallel lateral apodemes (figs. 224, 225–228, 328).

Triaeris bodanus Chickering, 1968: 353 View in CoL , figs. 1–5 (male holotype from Simla [currently William Beebe Tropical Research Station, 10 ° 41910 N 61 ° 169590W], Arima Valley, Saint George, Trinidad and Tobago, Apr. 25, 1964, A.M. Chickering col., in MCZ 20549 PBI_OON 5393, examined).

DIAGNOSIS: Males of Simlops bodanus resembles those of S. guyanensis and S.

guatopo by the filiform distal third of embolus but can be recognized by the combined presence of longer embolus, with a basal constriction, and a massive hyaline conductor, without basal sclerotizations (figs. 314, 315). Females are unique in the genus in presenting a small, round, anteriorly positioned dorsal abdominal scutum (fig. 248); they are also remarkable for the wide, tubularshaped anteromedian rod (fig. 329).

MALE (PBI_OON 5393, figs. 7, 21–24, 229–242, 287, 314, 315): Total length 1.80. Carapace dark red-brown, sternum and mouthparts orange-brown, legs pale orange, without color pattern; abdomen soft portions pale white; abdominal scuta orange-brown. Sternal microsculpture covering almost entire surface, absent in front of coxae. Endites with retrolateral and median processes inconspicuous; prolateral projection long and slender, folded retrolaterally, with a distal, posteriorly projected small triangular process (figs. 237, 238, 287). Postepigastric scutum almost semicircular, covering about 3/4 of abdominal length. Palp: embolus long, slen- der, tip curved dorsally, conductor as long as embolus, semitranslucent with dorsal sclerotized strip, distally with short, filiform processes, originating at the bulbus, adjacent to embolar insertion (figs. 234–236, 239–242, 314, 315).

FEMALE (PBI_OON 37039, figs. 243– 250, 329): Total length 2.40. Dorsal scutum present, oval, small, restricted to front of abdomen. Epigastric furrow medially slightly recurved, not medially sclerotized, without median notch, not connected laterally to anterior spiracles; postepigastric scutum with anterior margin not sclerotized, extending well beyond groove connecting posterior spiracles, enlarged laterally around posterior spiracles, without discrete lateral sclerotizations. Genitalia with strong, tubular posteromedian rod, anteri- or end blunt, with spinelike processes; transverse bar thin, procurved, without rectangular plate; posterior receptaculum conspicuous, rounded, with unsclerotized borders, enclosed by long, parallel lateral apodemes (figs. 250, 329).
