Leptopholcus delicatulus Franganillo, 1930: 59 View in CoL .

Huber and Pérez González, 1998: 251 256, figs. 1 5, 11 21.

Leptopholcus conicus Franganillo, 1931: 286 . id. 1934: 153. id. 1936a: 46. id. 1936b: 78 (first synonymized by Franganillo 1936b, erroneous preference of junior synonym).

Micromerys dalei: Bryant, 1940: 296 297 (erroneous synonymization of delicatulus View in CoL with dalei ).

NEW RECORDS: CUBA: Oriente: S. Vicente, Caney, Nov. 1956 (no collector given), 23 in AMNH. Cuabitas, Santiago de Cuba, Dec. 18, 1955 (collector not given), 1♀ in AMNH.

NOTE: Bryant s (1940) material was recently thought to be lost (Huber, 1997a, Hub- er and Pérez González, 1998), but it has resurfaced at the AMNH, and will be returned to the MCZ.

Leptopholcus hispaniola , new species Figures 300 301, 308

TYPE: Male holotype from Parque Nacional Bermudez Cienaga, La Vega Prov., Dominican Republic ; 1100 m elev., tropical ev- 301. Palpal trochanter. 302 305. L. dalei (Petrunkevitch) . 302. Left procursus, retrolateral view. 303. Bulbal projections (left bulb). 304. Bulbal appendix. 305. Palpal trochanter. Arrows point to emboli ; arrow with shaft points to distinctive apophysis on L. jamaica appendix; asterisks mark unci. Scale line for all drawings: 0.2 mm.

ergreen forest, malaise, July 19 Aug. 2, 1995 (S. & J. Peck), in AMNH.

ETYMOLOGY: Named for the Island of Hispaniola. The specific name is a noun in apposition.

DIAGNOSIS: Close relative of L. delicatulus , distinguished by the shorter palpal trochanter apophysis (compare figs. 294, 301), the thicker palpal tibia (0.37 mm diameter in two L. hispaniola males versus 0.28 0.33 mm in five L. delicatulus males), and the broader bulbal appendix (compare figs. 293, 300).

MALE (holotype): Total length 3.8, carapace width 0.74; leg 1: 30.4 (6.9+0.3 +7.5+14.0+1.7), tibia 2: 5.0, tibia 3: 3.1, tibia 4: 4.5; tibia 1 l/d: 102. Habitus exactly as in other Caribbean Leptopholcus (cf. figs. 22a b in Huber, 1997a). Carapace ochre-yellow, ocular area with brown band between eye triads; AME represented by black spots, but apparently without lenses; distance PME- ALE about 15% of PME diameter. Clypeus brown, sternum whitish; chelicerae ochreyellow, with apophyses as in L. dalei and L. delicatulus (cf. fig. 24 in Huber, 1997a; fig. 11 in Huber and Pérez González, 1998). Palps ochre-yellow, trochanter apophysis very short: 0.12 0.13 mm in two males; procursus brown ventrally and distally, apparently identical to that of L. delicatulus (cf. fig. 291); bulb whitish with black apophyses, with distinctive appendix. Legs light ochreyellow, with dark patellae and tibia-metatarsus joints; apparently without spines, without curved and vertical hairs (many hairs missing); retrolateral trichobothrium of tibia 1 at 4%; tarsus 1 with ~ 35 pseudosegments. Opisthosoma grayish, without spots (bleached?).

VARIATION: Tibia 1 in other male studied: 6.9; in this male there is absolutely no trace left of the AME, but the genitalia are indistinguishable from those of the type specimen.

FEMALE ( Haiti): Total length 3.6, carapace width 0.65; leg 1 missing. Opisthosoma even more elongated above spinnerets than in male, with dark spots dorsally; AME more clearly present, apparently with lenses; internal genitalia as in fig. 308. An egg sac accompanies the female, and is remarkable for being relatively tightly woven, in contrast to the few threads of Metagonia egg sacs.

DISTRIBUTION: Known from one locality in

Haiti, and two localities in the Dominican Republic.

MATERIAL EXAMINED: DOMINICAN RE- PUBLIC: La Vega: type above; forest between Hato Mayor and Sabana de la Mar, July 20, 1935 (W. G. Hassler), 13 in AMNH. HAITI: Port-au-Prince : Damiens, Nov. 10, 1959 (A. M. Nadler), 1♀ in AMNH .

Leptopholcus jamaica , new species Figures 294 299, 307

TYPE: Male holotype from Askenish , Trail to Dolphin Head, Hanover Prov., Jamaica ; June 24, 1954 (A. M. Chickering), in MCZ .

ETYMOLOGY: Named for the Island of Jamaica. The specific name is a noun in apposition.

DIAGNOSIS: Easily distinguished from the other Caribbean species by the long apophysis originating from the bulbal appendix (arrow with shaft in fig. 297); also by the tip of the appendix projecting over the spine (fig. 298), and the very long, almost straight palpal trochanter apophysis (fig. 299).

MALE (holotype): Total length 4.8, carapace width 0.84; leg 1: (8.5+0.4+8.1+16.1, tarsus missing), tibia 2: 5.6, tibia 3: 3.3, tibia 4: 5.5; tibia 1 l/d: 102. Habitus exactly as in other Caribbean Leptopholcus (cf. figs. 22a b in Huber, 1997a). Carapace ochre-yellow, ocular area with large brown, about triangular mark; AME as in L. delicatulus (small, but with lenses); distance PME-ALE about 15% of PME diameter. Sternum whitish; chelicerae ochre-yellow, with apophyses as in L. dalei and L. delicatulus (cf. fig. 24 in Huber, 1997a; fig. 11 in Huber and Pérez González, 1998). Palps ochre-yellow, trochanter apophysis very long: 0.36 0.37 mm in three males; procursus brown ventrally and distally, with distinct distal apophyses and laminae (figs. 295 296); bulb whitish with black apophyses, with distinctive apophysis originating from basis of appendix (arrow with shaft in fig. 297). Legs light ochre-yellow, with light brown patellae and tibia-metatarsus joints; apparently without spines, without curved and vertical hairs; retrolateral trichobothrium of tibia 1 at 4.5%. Opisthosoma ochre-yellow, with some very faint darker spots dorsally.

VARIATION: Tibia 1 in two other males: 7.0, 8.0.

FEMALE (Heremitage Reservoir): Tibia 1: 5.9. In general very similar to male, but without brown mark on ocular area. Internal genitalia as in fig. 307.

DISTRIBUTION: Known only from Jamaica.

MATERIAL EXAMINED: JAMAICA: Hanover: type above, with 1 juvenile ; St. Andrew: Heremitage Reservoir , Feb. 5, 1957 (A. M. Chickering), 13 1♀ in MCZ ; Grove Place , July 15, 1960 (Vauries), 13 in AMNH .
