A new species of Antillorena from Colombia ( Araneae : Zodariidae : Lachesaninae )

The genus Antillorena Jocqué, 1991 is reported in Colombia for the first time and A. sanjacintensis sp. nov. is described for the north of the country. This new species is diagnosed with the type species Antillorena polli (Simon, 1887). A taxonomic key and a map with the distribution of all species of the genus are included.

Antillorena Jocqué 1991 is a genus with Neotropical distribution, which currently includes three valid species from the Lesser Antilles and Brazil (World Spider Catalog, 2018).According to Gertsch (1961) the species of this genus have cursorial habits and are characterized by building burrows lined with silk and closed with a wafer-type trapdoor.The first species of the genus was described for the Lesser Antilles under the name Storena pollii (Simon) (sic) in Hasselt (1887) (current spelling Storena polli; see World Spider Catalog, 2018).However, later Jocqué (1991) considered that this species was misplaced, proposing Antillorena Jocqué to include S. polli.Recently, Brescovit & Ruiz (2011) described two new species of the genus, A. gaia and A. patapata, expanding distribution to South America.Antillorena is distinguished from other members of the family by the long and coiled embolus and conspicuous proximal tegular apophysis in the male palp, as well as, the very long copulatory ducts, with more than three turns surrounding the elongated spermathecae in the female epigynum (Jocqué 1991;Brescovit & Ruiz 2011).
The aim of this study is to describe a new species from Bolivar and Atlántico Departments, northern Colombia, which represents the first record of the Antillorena in the country.In addition, an identification key and a distribution map of all currently known species in the genus are provide, along with supplementary documentation of A. polli.

MATERIAL AND METHODS
Specimens were preserved in 96% ethanol.Male palps were detached from the body and illustrated in ventral and retrolateral views.Female epigynum was dissected and immersed in KOH 10%, in order to clarify soft tissue, to study internal structures.Measurements are expressed in millimeters and were preferentially taken in the left side of specimens.The photos were taken with a Leica MC170 HD camera attached to a Leica M125 stereoscope.Terminology and format of descriptions follow Jocqué (1991).Spine notation follows Petrunkevitch (1925).

Etymology.The specific name refer to toponym San Jacinto, one of the municipality where the type specimens were collected.
Diagnosis.Males of A. sanjacintensis sp.nov.are similar to those of A. polli (see Figs 12,13;Jocqué, 1991:35, figs 48-51, 94) by the simple ventral tibial apophysis, the origin and shape of the cymbium basal projection and by the size, direction and shape of the median apophysis.However, can be distinguished by having the retrolateral tibial apophysis with the distal area shorter and acuminate at the tip, narrower and longer proximal tegular apophysis and by the shorter and bent conductor than in A. polli 8,9;(14)(15)(16)(17).The females resemble those of the A. polli by the long folding of the ducts with more than seven turns, but differs by the pore of the atrium at the posterior border of the median septum (Figs 6, 10) and by presenting eight turns of the ducts (Figs 7,11).
