Figs 40–45
Material examined. Holotype: male (NSYSUB), Taiwan, Pingtung County, Chunri Township, Mt Dahan, 22°24'25" N, 120°45'21" E, 1200 m a.s.l., 15 December 2009, leg. M.H. Hsu; Paratypes: 11 males, 25 females, 1 fragment (NSYSUB), 2 males, 2 females (IBSS), 2 males, 2 females (ZMUM), 1 male, 1 female (NMNS, 6702 – 011), 1 male, 1 female (HNHM), same locality, together with holotype, 15 December 2009, leg. M.H. Hsu.
Diagnosis. Differs from congeners mainly by the shape of the gonopod opisthomere, in which the anterolateral lamella is broadened distally into a lobiform plate with a curved apical outgrowth, as well as by the presence of minute setules at the caudal margin of metazona.
Description. Male. Length 23 – 28 mm, vertical diameter 1.0 mm with 64(– 4), 64(– 5), 69(– 5), 69(– 3) segments, excluding telson. Coloration dark brown with three narrow, longitudinal, dark brown stripes, one mid-dorsal and two lateral ones level to ozopores, so that dorsum showing two vague, somewhat lighter, broad, ribbon-shaped, longitudinal stripes. Collum with two transversely-oval, large, yellowish spots. Clypeolabral part of head lighter. Anal valves lighter, as usual. Antennae and legs brown, eye patches black.
Eye patches subtriangular, composed of at least 29 ocelli. Labral setae as in A. immensus sp. nov. Genae with a small low knob on cardo. Gnathochilarium as in A. oligosegmentatus sp. nov. Length ratios of antennomeres 2–7 as 5.4:5.0:4.0:5.0:2.8:1, width ratios as 1.1:1.1:1.2:1.7:1.6:1, respectively. Antennomeres 5 and 6 each with an incomplete distodorsal corolla of a few sensory bacilli, these being especially few on 6th antennomere.
Body subcylindrical, slender. Ozopores lying behind stricture without touching it. Metazona with striations extending behind to caudal margin; 12–13 striae on metazonital surface between dorsal midline and ozopore, or 7– 8 striae per square lying between ozopore and axial line. Caudal margins of metazona with minute, very sparse, barely visible setules. Caudal parts of prozona lying below ozopore level, finely striolate longitudinally and slightly obliquely. Caudal projection of epiproct as in A. oligosegmentatus sp. nov., but a tiny claw-shaped process curved dorsally.
Legs as in A. oligosegmentatus sp. nov. Claw at base with a long filament ventrally. Legs 1 with strong setae ventrally and a ventral papillate knob on telopoditomere 2, apex with traces of papillae (Fig. 40). Penes of medium length, deeply bifid (Fig. 41).
Gonopods. Promere somewhat intermediate in shape between a quadrangle and a triangle, mesal margin somewhat curved rectangularly caudad; flagellum relatively long; rudimentary telopodites well-visible (Fig. 42).
Opisthomere (Figs 43, 44) as in A. oligosegmentatus sp. nov., but distal part of al extended into a curved apical outgrowth (p) while opisthomere apex with an elongate, thin, mesal lobe (ml).
Female. Length 20–30 mm, vertical diameter 1.0 – 1.8 mm, with 53(– 4), 55(–4), 57(–4), 58(– 4), 61(–3), 70(–3) segments, excluding telson. Broad, ribbon-shaped, light, longitudinal stripes on dorsum rather distinct. Claws with long ventral filaments only, these often broken off, leaving short stumps instead. Vulvae as in Fig. 45. Operculum longer than bursa, with two rows of setae on anterior face (at least four setae in each row in the vulvae examined). Apical margin of operculum with two low prominences. Bursa setose, with four setae on lateral and with three setae on mesal sclerites, five setae on each side of median plate of posterior sclerite.
Name. The specific epithet refers to the minute setules present at the caudal edge of metazona.
