Indopacifica tyida Pfingstl, Shimano & Hiruta, 2021 View in CoL

Larva and protonymph unknown.

Deutonymph

Length (N = 3): 250–295 (mean 276 μm).

Gastronotic region ( Figure 12 View Figure 12 (c)). Fifteen pairs of notogastral setae; c 1-3, da, dm, dp, la, lm, lp, h 1-3 and p 1-3, all short, approximately same length (6–10 µm).

Podosoma and venter. Epimeral setation 1-0-1-1. Two pairs of short genital setae (ca. 4 µm) arranged in longitudinal row. Two pairs of short adanal setae ad 1-2 (ca. 3 µm) flanking anal valves. Two pairs of vestigial anal setae.

Legs ( Figure 13 View Figure 13 ). Claws with one proximoventral tooth. Setation and solenidia are shown in Table 7.

Tritonymph

Length (N = 1): 325 μm.

Gastronotic region ( Figure 12 View Figure 12 (b)). No difference to deutonymph.

Podosoma and venter. Epimeral setation 1-0-1-1. Three pairs of short genital setae (4 µm) in longitudinal row. Two pairs of adanal setae and two pairs of short anal setae an 1-2 (4 µm).

Legs. Claws with one proximoventral tooth. Setation and solenidia are shown in Table 7.

Remarks

Juveniles of the Japanese Indopacifica species are more or less identical in terms of habitus, prodorsal, notogastral and ventral setation. The only found differences between I. taiyo and I. tyida juveniles concern the development of tibial setae, i.e. the antiaxial lateral setae on tibia I and III appear already in the deutonymphal stage in I. tyida but they appear later (possibly in tritonymph but due to lacking data not confirmed yet) in I. taiyo .
