Diagnosis. This species differs from other congeners by the long antennae and antennal segment III being as long as IV.

Description. Macropterous; general habitus and morphology as of other species of this genus; color stramineous with darker brown patches on deltg II–VII and anterior part of scutellar disk; scutellum with a pale patch of inverted V-shape ( Fig. 1 View FIGURES 1–10 ).

Head. Distinctly longer than wide (29:22); clypeus medially elevated, genae anterolaterally dilated and laminate; antennae 1.35 times as long as width of head, antennal segment III as long as IV, length of antennal segments I: II:III:IV = 5:6:9:9; vertex with a double longitudinal row of tubercles at middle and a transverse row on posterior margin.

Pronotum. Wider than long (46:26), posterior lobe roundly elevated, lateral margins converging anteriorly with three larger tubercles on anterior lobe and few smaller ones on posterior lobe, disk with two pairs of distinct carinae.

Scutellum. Basal triangular elevation with two pairs of large tubercles overlapping pronotum and two smaller ones at middle; lateral margins tuberculate along excision for exposed lateral margin of corium reaching deltg V, granulate posteriorly, median carina with one row of tubercles, surface of disk with flat punctures.

Abdomen. Lateral margins of deltg II–VII with a double row of round tubercles, the posterior one yellowish, both anterior ones dark brown; tergite VIII with exposed transverse sclerite; spiracles II–VI ventral, VII–VIII lateral.

Genitalia. Paramere blade as in Fig. 26 View FIGURES 26–29 .

Female. Basically as male but of larger size; exposed transverse sclerite of tergite VIII present.

Measurements. ♂♂ (n = 5): body length 2.85–3.10 mm, width of abdomen 1.20–1.35 mm; ♀♀ (n = 5): body length 3.25–3.45 mm, width of abdomen 1.40–1.60 mm.

Etymology. Named after our friend Tadashi Ishikawa, an excellent student of Heteroptera and collector of two new species described in this paper, in appreciation of his support and generous donation of specimens.

Ecology. Several specimens were collected on Quercus spp. ( Fagaceae ) ( Fig. 33A–C View FIGURE 33 ).

Distribution. Nipponocalisius ishikawanus sp. nov. is the only calisiine so far known from the main islands of Japan (Honshu, Shikoku, Kyushu) and its outlying islands (Hachijo Island of the Izu Islands, Tsushima Island, Goto Islands) ( Fig.34 View FIGURE 34 ).

Remarks. Calisius sp. illustrated by Tawara (1977: Fig. 30a View FIGURES 30–32 ) and Tomokuni & Ishikawa (2002: Fig. 31a View FIGURES 30–32 ) pertains to this new species; their voucher specimens were examined ( Figs. 30b, 31b View FIGURES 30–32 ). The unavailable name Nipponocalisius ... ishikawanus , mentioned by Heiss, pertains to this new species.
