Epigyne/vulva. As in diagnosis with EF slightly wider than long ( Fig. 5a View FIGURE 5 ) or as long as wide ( Figs 6a, d View FIGURE 6 ); longitudinal sclerotized strip on MS present ( Fig. 6b View FIGURE 6 ) or absent ( Fig. 5b View FIGURE 5 ); CD short, vulva robust and compact ( Figs 5c View FIGURE 5 , 6c View FIGURE 6 ) compared to other walckenaeri group members.

Colouration (Live). Yellowish brown with distinct dark pattern on prosoma, dorsal opisthosoma with a long cardiac mark, legs clearly banded ( Fig. 47b View FIGURE 47 ) to paler bands ( Fig. 47c View FIGURE 47 ); specimen in ethanol reddish brown with pale body ( Fig. 47a View FIGURE 47 ).

Remarks. Simon (1897c) described only the female of E. laevatus comb. nov. but he listed two different field numbers corresponding to specimens collected from the type locality, Shebelle River ( Simon 1897c: 389). My investigation in the collection of NHM revealed that the second number (1.9.94) refers to a male sympatrically collected from the type locality and definitely examined by Simon (1897c). According to Article 72.4.1 of the Code ( ICZN 1999), the male belongs to the type series, and is, as the female, a syntype. The type specimens were collected by the American investigator, A.D. Smith during “The first expedition from Somaliland to Lake Lamu ” in 1893–94. The female is redescribed but the male, even though it is a syntype, is described for the first time.

Known geographical distribution and habitat. East Africa from southern Ethiopia to the horn of Africa in Somalia and Djibouti (new country record), and the Arabian Peninsula in Yemen (new country record), Saudi Arabia (new country record) and Oman (new country record) ( Fig. 70a View FIGURE 70 ).
