Remarks.
The 18 specimens recorded above (Fig. 1 C, D View Figure 1 ) matched well with the descriptions and illustrations of Acalypta carinata ( Péricart 1978, 1983) in terms of their morphological characteristics, particularly the structures of the pronotum and hemelytron (Figs 3 E – G View Figure 3 , 7 E – G View Figure 7 , and Fig. 13 C, D View Figure 13 ). Therefore, the specimens examined were identified as A. carinata .
Acalypta carinata is most similar to A. platycheila in general appearance, but the former can be distinguished from the latter based on the following characters (Figs 3 E – G View Figure 3 , 7 E – G View Figure 7 , 13 C, D View Figure 13 ) (cf. Péricart 1978, 1983): posterior part of pronotal hood usually triangular (usually semicircular in A. platycheila ); lateral carinae slightly close to each other toward anterior ends (parallel or slightly separated in A. platycheila ); calli smooth (rough in A. platycheila ); and costal area of hemelytron with usually 2 rows of areolae throughout its length, sometimes 3 rows in basal part, and sometimes a single row in middle part (with usually a single row throughout its length and sometimes 2 rows in basal part in A. platycheila ). Morphological differences between A. carinata and the nine other Japanese species are presented in the identification key below.
The teratological form of the pronotum and hemelytron was confirmed in A. carinata from Japan, and one examined specimen possessed malformations of the right paranotum and hemelytron (Figs 1 D View Figure 1 , 3 G View Figure 3 , 7 G View Figure 7 ), as reported in many lace bugs ( Štusák and Stehlík 1980, 1982).
Distribution.
Austria, Belgium, Byelorussia, Croatia, Czech Republic, Denmark, Estonia, Finland, France, Great Britain, Germany, Hungary, Ireland, Italy, Japan (Hokkaido, Rishiri Island), Latvia, Luxembourg, Moldovia, Mongolia, Netherlands, Norway, Poland, Romania, Russia, Slovakia, Slovenia, Spain, Sweden, Switzerland (Fig. 17 View Figure 17 ) ( Péricart and Golub 1996; Aukema et al. 2013; Aukema 2025). Acalypta carinata is newly recorded from Japan.
Host plant.
The Japanese population of Acalypta carinata feeds on indeterminate mosses growing in marshlands or the forest floor of deciduous broad-leaved forests in captivity. In other distribution areas, Abietinella abietina (Hedw.) M. Fleisch. ( Thuidiaceae ), and indeterminate mosses have been recorded as host plants for this species (cf. Drake and Ruhoff 1965; Péricart 1983).
Bionomics.
Acalypta carinata is found only in marshlands in Hokkaido, Japan and is dominant among Acalypta species in humid environments, such as marshlands and riparian forests in Hungary ( Rédei et al. 2004), suggesting that it mainly inhabits humid environments regardless of the region. However, this species inhabits the forest floor of deciduous broad-leaved forests exceptionally on Rishiri Island, near Hokkaido, where no other Acalypta species has been recorded.
In Japan, adults and nymphs were observed in August and September, respectively. In Europe, adults were collected between April and October, and nymphs were confirmed in almost all seasons; the overwintering stage comprised nymphs (cf. Péricart 1983; Rédei et al. 2004).
