Khamisia banisad Saaristo and van Harten, 2006: 136 View in CoL , figs. 18–21 (female holotype from Khamis Bani Sa‘ad, Yemen, in MZT; examined).
DIAGNOSIS: Females resemble those of K. hayer but have a longer median genitalic process (fig. 100).
MALE: Unknown.
FEMALE (PBI_OON 9870, figs. 97–100): Total length 1.53. Anterior genitalic process long, distally widened, lateral processes with recurved, rounded tips that may serve as spermathecae.
MATERIAL EXAMINED: YEMEN: Al Mahwit: Khamis Bani Sa‘ad , June 23, 1999, leaf litter in and around banana plantation (A. van Harten, MZT 3066, PBI _ OON 9870 ), 1♀ (holotype) .

Khamisia atlit , new species
Figures 101–124 View FIGURES 101–115 View FIGURES 116–128. 116–124
TYPES: Male holotype and male paratype from Atlit, Haifa, Israel (Sept. 18–23, 2005; M. Vonshak), deposited in TAU ( PBI _OON 51500) .
ETYMOLOGY: The specific name is a noun in apposition taken from the type locality.
DIAGNOSIS: Males resemble those of K. hayer but have a longer embolus with a smooth median portion (fig. 111); females differ from those of K. hayer and K. banisad in having narrow lateral genitalic processes without rounded tips (fig. 123).

Khamisia holmi , new species
Figures 125–143 View FIGURES 116–128. 116–124 View FIGURES 129–143

ETYMOLOGY: The specific name is a patronym in honor of the collector of the holotype, the late Swedish arachnologist, Åke Holm.

Khamisina , new genus
TYPE SPECIES: Khamisina kivu , new species.
