Dissoloncha Falconer, 1923  

Macrocheles (Dissoloncha) Falconer, 1923: 151   . Type species: Macrocheles superbus Hull, 1918   , by original designation and monotypy.

Geholaspini with a distally bifid, elongate, triangular epistome ( Fig. 1 View FIGURES 1 – 7. 1 – 3 ); ventri-anal shield with three pairs of pre-anal setae; inguinal pores on anterior lateral angles of ventri-anal shield ( Fig. 2 View FIGURES 1 – 7. 1 – 3 ); with two pairs of postepigynal platelets, these sometimes more or less fused to ventri-anal shield; sacculus large, spherical, strongly convoluted ( Fig. 3 View FIGURES 1 – 7. 1 – 3 ). Males with separate sternogynal and ventri-anal shields; chelicera with short, dorsally directed spermatodactyl; legs II with small spurs on femora and genua, legs IV with spurs on trochanters and femora.

Notes. Dissoloncha   was redescribed by Hyatt & Emberson (1988) and associated with Geholaspis   rather than Macrocheles   . The unique spherical sacculus was illustrated by Takaku (1997). The genus needs no further description. It includes a single species distributed in coastal areas throughout the cool temperate regions of the Holarctic ( Krantz, 1972; Hyatt & Emberson, 1988; Takaku, 1997).

Included species: D. superbus ( Hull, 1918)
