Ordo: Araneae
Familia: Selenopidae
Genus: Selenops
Name
Selenops pensilis Muma, 1953 – Wikispecies link – Pensoft Profile
- Selenops pensilis Muma 1953[1]: 42, Fig. 73 (♀, examined).
- Selenops pensilis:Alayón-García 1992[2]: 2, Fig. 2 (♀).
Type material
Holotype female: Grand'Anse, Haiti, Uhler (MCZ, examined).
Other material examined
DOMINICAN REPUBLIC: La Altagracia: along 4–5 km S caseta Gran Chorra, near Palmilla, 5.V.1992, 1♀ (MNHNSD); Punta Cana, Punta Cana Resort, 5-8 July 2006, sea level, S. Crews, under rock on egg sac, 1♀ (EME sel_528).
Diagnosis
Though very similar to Selenops enriquillo sp. n., the genital openings and median field are more posterior on the epigynal plate. Internally, the ducts and posterodorsal fold are shaped differently (Figs 155–156). Males unknown.
Remarks
This species is closely related to Selenops enriquillo sp. n. It differs in genitalic details and molecular genetic makeup. As the specimens from Alayón-García (1992)[2] were unable to be examined, it is unclear if he was referring to Selenops pensilis or Selenops enriquillo sp. n.
