Aegyptobia Sayed 1950

Aegyptobia Sayed, 1950 Type species: Aegyptobia trägårdhi Sayed, 1950: 1019. Diagnosis (modified from Seeman & Beard 2011, Beard et al. 2012). Adult female. Body usually rounded, ovate to obovate, often no more than 1.5 times longer than wide (measured as v2–h1 and sc2–sc2), rarely ca. 2 times longer than wide, exceptionally rarely much more than 2 times longer than wide (e.g. A. prolixa Meyer); prodorsal and opisthonotal shields often well-developed and ornamented with patterns of striae or reticulation. Palps 5-segmented; palp tarsus usually with 3 terminal phaneres (all well-developed). Anterior margin of prodorsum smoothly rounded or with short median notched projection; dorsal opisthosoma with full complement of dorsal setae (n.b. A. ericae Meyer & Van Dis was incorrectly recorded with setae f2 absent (Beard et al. 2012)); dorsal setae variable but typically homogenous in form and none flagellate. Ventral plate weakly developed or absent; genital plate weakly developed and with g1 and g2 inserted on posterior margin; anal plates usually well-developed, with three pairs of ps setae in a longitudinal line along medial margin or in a weak triangle (e.g. A. prolixa Meyer, A. gahnia sp. nov.); metapodal plates often developed; supernumerary coxal setae absent. Leg chaetotaxy variable, but tibiae I–IV stable 4-4-3-3 (seta lʹʹ lacking on tibiae I–II); usually with trochanters 1- 1-1-1 or 1-1-2-1; femora I-II 4-4 or 3-3 (seta l’ sometimes absent); femora III–IV usually 2-1; genua I–IV usually 3-3-1-0, with several exceptions (e.g. 2-2-0-0 in A. pennatulae Baker & Tuttle, A. pomaderrisae Collyer, A. vannus Pritchard & Baker; 2-2-1-0 in A. nina (Pritchard & Baker); 1-1-1-0 in A. nummulus Chaudhri); tarsi usually 9(1)- 9(1)-5-5, rarely with tcʹʹ absent on tarsi I–IV (e.g. A. pennatulae, A. vannus). Femora I–II with d inserted dorsally, typically similar form to dorsal idiosomal setae. Tarsal claws either pad-like (macswaini species group) or claw-like (trägårdhi species group). Adult male. Lacking additional solenidion on tarsi I–IV.
