 Dipoena appalachia Levi, 1953 



(Figs. 30-31) 



Material Examined. Canada: Quebec: Pare National de la Yamaska [45.42°N, 72.62°W]

 mixed forest, A. Mochon (CPAD); lo 27.vi.-04.vii.2006, pitfall, mixed forest, A. Mochon 

 (CPAD). 



Diagnosis. Dipoena appalachia closely resembles Dipoena nigra (Emerton, 1882) but 

 differs by the evenly yellow-brown legs lacking the much darker femur and patella I present 

 in D. nigra. The male palp is characterized by the sperm duct (SD) acutely curved (Fig. 3 1 ), 

 the pointed distal part of the radix (R) and the conductor (C) form (Fig. 31). 



Distribution. Southeastern United States to Maryland (Levi 1953); Canada: Quebec. 



Remarks. Dipoena appalachia displays variability in the palp configuration (see Levi 

 1953, Figs. 24, 25, 27). However, the specimens collected in the Pare National de la 

 Yamaska showed no variation. These first Canadian records represent an unexpected range 

 extension for the species. The female of D. appalachia is unknown.

Diagnosis. Keijia alabamensis is distinguished by the combination of the following 

 characters: male palp with thick embolus (E) (Fig. 32), long and pointed median apophysis 

 (MA) (Fig. 32). Females are characterized by their dark abdomen with a distinct apical 

 white mark (Fig. 33), epigynum with large, oval atrium (A) (Fig. 34), copulatory ducts (CD) 

 large, touching medially and narrowing down into one loop (Figs. 35, 36). The genitalic 

 configuration of the species is quite unique, especially the rounded shape of the atrium and 

 the male embolus, which allows an easy distinction from its congeneric members. 



Distribution. Eastern North America, north to Quebec and New Brunswick, with a few 

 records from California (Levi 1957). 



Remarks. Keijia alabamensis has been transferred from Theridion by Yoshida (2001), 

 with three other North American species (Platnick 2007). The species was included on the 

 list of probable records for Quebec of Hutchinson and Belanger (1994).
