Arrhopalites habei Yosii, 1966: 521­523 , fig. 53.

Material examined: Lectotype ♀ in alcohol, 1 paralectotype ♀ in alcohol. Several paralectotypes mounted in four slides, JAPAN, Kyoto, Iwakura , 10­vii­1968, R. Yosii leg. Yamagushi, Akiyoshi, Okahuji leg. Okinawa, Ommadake, 13­x­1960, Nishihira leg. Kyoto, Daimonji, 8­ix­1968, Sawada leg., MHN.

Principalis­group ( Fig. 4 , A­K). Body setae figure D. Antennae of lectotype ~ 2X as long as the cephalic diagonal. Ant. IV with seven subsegments (Fig. A), apex with a capitate sense rod (Fig. B). Ant. III without basal swelling; sense organ (Fig. C) with 2 parallel sense rods in separate pits; seta Aai club­shaped and acuminate; Api and Ape short and acuminate; Ae, Ap and Ai normal elongate setae. 1+1 eyes, sparse light brown pigment over the body (in alcoholic specimens). No cephalic spines, seta M5 absent (Fig. J). Metatrochanteral organ (seta D2) elongate (Fig. G). All ungues with a clear inner tooth and no tunica (figs. K, a­c). All unguiculi with a clear corner tooth, and apical filament exceeding unguis tip. Corpus tenaculum with two setae (Fig. H). Dens with 7 dorsal E setae, E1 and E3 strongly spinelike; 3 spinelike L setae present; D1­2 and Id1­4 present (Fig. E); 4 ventral setae rows (3,2,1,1) (Fig. E). Mucro narrow, gutter­like, both edges serrate (Fig. F). Anal valve without cuticular spines; setae C1 forked C2­9 swollen basally, chaetotaxy (Fig. I). Female subanal appendage rod­like, slightly flattened and distal two thirds barbed (Fig. I).

Biogeographic zone 3a, 18.

Remarks:This species can be recognized by the presence of the seta E9 at the anal valve and the shape of the female subanal appendage.
