1962 by the length and shape of the notogastral and the ventral setae. Also, E. pallida aegyptica ssp.n. stands nearest to E. pallida pacifiea Aoki, 1965, but it can be easily separated by the slope of the epimeral ridges I and the absence of the connecting horizontal ridge, the form of sensillus (in E^ pal lida pacifi ea the thickened part of sensillus is shorter than its shaft), the shape of the outer margin of the posterior coxisternal plate (in E. pallida pacifiea it is smooth and straight), and the length and the relative distances between the epimeral hairs. Key for the known members of Epilohmannids 1 (4) Strong aggenital neotrichy present, with 8-16 pairs of aggenital setae 2 (3) Outer margin of epimere II serrate. Only 8-12 pairs of aggenital setae. ­Fiji mul tiset osa Hammer, 1971 3 (2) Outer margin of epimere II smooth. 16 pairs of aggenital setae. - Japan ovata Aoki, 1960 4 (1) Only 3-5 pairs of aggenital setae present. 5 (18) Distal half of sensillus spindle-shaped or fusiform. 6 (11) Seta ft" on tarsus IV thick, short and thorn-like. 7 (6) Notogastral setae cx and C2 either arising on same horizontal level, or se­ta C2 arising slightly anterior to seta c^ . Distance Ci~c 2 approximately equ­als that of ci-c^ . No square outline obtained by joining points of insertions between setae ci - C£ - C3 - d 1f respectively (Fig. 1 ). Seta ps^ almost one and half times as long as seta oj. - Ghana pallida pallid a Wallwork, 1962 8 (7) Notogastral seta C2 always arising posterior to seta c^. Square outline ob­tainable by joining points of insertions of setae ci -'. C2 - 03 - di , respec­tively (Fig. 17 ). Seta psi almost one and half times as long as seta ej. 9 (10) Outer margin of coxisternal plate between legs III and IV smooth, or slightly of a uniform concavity. Epimeral setae, especially those on epimera 3 and 4, short excepting long seta 3c. A strong horizontal chitinous ridge connec­ting two epimeral ridges I. Distace c^ - C2 nearly equal to thatbetweenC2~ Cg. - Hawaii and Laysan islands pall id a pacifiea Aoki, 1965 10 (9) Outer margin of coxisternal plate between legs HI and IV strongly articulate and sinuous. Epimeral setae long, seta 3b much longer than 3c. No horizon­tal ridge connecting epimeral ridges I. Distance C2 - c 3 distinctly shorter than ci - C2- - Egypt pallid a aegyptica ssp.n. 11 (6) Seta ft" on tarsus of leg IV thin, long, barbed and setiform. 12 (13) Tarsus of leg TV without any thorn-like hairs though distal halves of setae a" and pv" expanded, spatulate in form. - Japan spathulata Aoki, 1970
