( Figures 2c, d, j, 5, 6, 9b)

L. hispaniola Huber 2000, p 77 –79, Figures 300, 301 (female not conspecific, see below).


Male holotype from Parque Nacional Bermudez Cienaga, La Vega Prov., Dominican Republic; tropical evergreen forest at 1100 m a.s.l., 19 July to 2 August 1995 (S. and J. Peck), in AMNH .


Distinguished from known Caribbean congeners by the shapes of the apophyses on the male genital bulb ( Figures 5a, 6a–c, 9b), by the shape of the procursus ( Figure 5b), by the short male palpal trochanter apophysis ( Figure 5b), and by the internal sclerotized structures in the female genitalia ( Figures 2j, 5c, d). From L. toma and L. baoruco also distinguished by the shorter abdomen tip ( Figure 2d).

Male (type locality)

For a detailed description of the male holotype see Huber (2000). All males from the type locality have distinct black spots in the area of the AME, lenses are either absent or not visible in the dissecting microscope; other eyes as usual: distance PME–PME 300 Mm; diameter PME 80 Mm; distance PME–ALE 20 Mm. Habitus as in Figure 2c, d; prosoma very pale ochre-grey, with darker band between eye triads extending over dorsal half of clypeus; sternum whitish, legs pale ochre, patellae and tibia–metatarsus joints dark (almost black), abdomen ochre-grey with black spots dorsally ( Figure 2c). Chelicerae not visibly different from those of L. baoruco (cf. Figure 3c), with indistinguishable distal apophyses ( Figure 6i). Palps as in Figure 5a, b; coxa unmodified, trochanter with small retrolateral and relatively short ventral apophyses, the latter with distal modified hair ( Figure 6h); femur with three small apophyses retrolaterally; procursus strongly bent dorsally, with distinctive distal structures ( Figure 6d); genital bulb with distinctive uncus and appendix and slightly sclerotized embolus ( Figures 5a, 6a–c, 9b); palpal tarsal organ capsulate ( Figure 6g). Prolateral trichobothrium absent on tibia 1, present on other tibiae. Gonopore with four epiandrous spigots ( Figure 6e). Spinnerets as in L. baoruco (see above, and Figure 6f). Serrated hairs on tarsi 4 as in L. toma (cf. Figure 8g).


All males (and females) from the Cordillera Central (La Cienaga; near Jima) have distinct AME spots (sometimes apparently even lenses), while males (and females) from all other localities lack these spots as well as any trace of AME lenses. The genitalia (male and female) in all these specimens are indistinguishable. Tibia 1 in 36 males: 6.3–8.3 (mean: 7.2).


The single female specimen available at the time of the original description was from Haiti, Damiens ( Huber 2000). The newly collected material clearly shows that this female specimen is not conspecific with the type specimen of L. hispaniola , but probably represents an undescribed species. Females of L. hispaniola have relatively short abdominal tips (similar to males), and the distinctive internal sclerotized structures in the genitalia differ markedly from those of the Haitian specimen (compare Figure 5d with Figure 308 in Huber 2000). Tibia 1 in 56 females: 4.7–6.6 (mean: 5.4). Epigynum as in Figures 5c, 6j; internal genitalia with oval pore plates ( Figures 5d, 6m). Palpal tarsus with short distal cone-shaped claw, pair of strong hairs, and capsulate tarsal organ ( Figure 6l). Figure 6k shows a female from La Cienaga with distinct AME pigment but without any trace of AME lenses. Serrated hairs on tarsi 4 as in male.
