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); ventri-anal shield with three pairs of pre-anal setae; inguinal pores on anterior lateral angles of ventri-anal shield (Fig. 2); with two pairs of postepigynal platelets, these sometimes more or less fused to ventri-anal shield; sacculus large, spherical, strongly convoluted (Fig. 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)
