Escaphiella magna , new species Figures 343–384 ; map 6

TYPE: Male holotype from Tepoztlán, 18 ° 589N, 99 ° 079W, Morelos, Mexico (May 5, 1963; W. Gertsch, W. Ivie), deposited in AMNH (PBI_OON 26830) .

ETYMOLOGY: The specific name refers to the relatively large size of these diminutive spiders.

DIAGNOSIS: Both sexes can easily be recognized by their large size, dark coloration, and pitted abdominal scuta. Males have a relatively short embolus that is transverse distally (fig. 364); females have a long, sinuous anterior epigynal sclerite (fig. 367).

MALE (PBI_OON 26829): Total length 2.90 (figs. 343, 359, 360, 369). Carapace dark red-brown, surface of elevated portion of pars cephalica granulate, sides granulate; lateral margins with blunt denticles (figs. 344, 345, 370, 371). Eyes: ALE circular, PME squared; ALE touching, ALE-PLE touching, PME touching throughout most of their length, PLE-PME touching (fig. 368). Sternum dark red-brown, without radial furrows between coxae I–II, II–III, III–IV, surface rugose, microsculpture covering entire surcliff), 16 ° 579N, 96 ° 279W, Apr. 30, 1963 (W. Gertsch, W. Ivie, AMNH PBI_OON 26833), 68, 6♀; 3 mi SE Tlacolula, 16 ° 569N, 96 ° 259W, Aug. 30, 1966 (J., W. Ivie, AMNH PBI_OON 26832), 48.

DISTRIBUTION: Central and southern Mexico (map 6).

face (figs. 346, 374). Chelicerae, endites, and labium red-brown. Endites with modified setae on apex. Abdomen ovoid; book lung covers small, very narrow; pedicel tube medium, with small, dorsolateral, triangular extensions (fig. 375), scutum extending far dorsal of pedicel (fig. 361, 372), scutopedicel region with series of ridges and median, round depression (figs. 347, 373, 375); sperm pore flanked be pair of depressions (figs. 348, 349, 366); dorsal scutum dark red-brown, covering full length of abdomen, no soft tissue visible from above, middle surface punctate, sides punctate; postepigastric scutum dark red-brown, sides punctate. PMS present (stereoscope). Legs dark red-brown. Right and left palps symmetrical, proximal segments pale orange; embolus dark, short, transverse (figs. 362–365); femur normal size; cymbium and bulb pale orange.

FEMALE (PBI_OON 26829): Total length 3.10 (figs. 351–358, 377, 380–383). Abdomen with soft portions of dorsum white (figs. 376, 379); anterior part of epigastric scutum with scutal ridges (figs. 378, 384). Epigynum with long opening (figs. 350, 367).
