Rhorus takagii ( Uchida, 1931) View in CoL

( Figs 9–17 View FIGURES 9 – 17 )

Monoblastus takagii Uchida, 1931 [in Takagi, 1931]: 24, 50; “ ♂ ” = ♀, Holotype: ♀, Korea, Ham-Kyong-Duk-Do (=Kankiyohokudo) (Mus. Sapporo). Takagi, 1931: 56, 57 (biol., hosts). Kim, 1955: 491 ( Korea: Ham-Kyong-Duk-Do). Townes et al., 1965: 244 ( Rhorus View in CoL , = nigrianalis Uchida, 1931, bibl.). Kasparyan, Khalaim, 2007 ( Korea, ex Pristiphora glauca Benson ). Kasparyan, 2012: 420,(“ ♂ ”= ♀, key, Russian). Kasparyan, 2012: 683 (key, English).

Monoblastus takagii var nigrianalis Uchida, 1931 [in Takagi, 1931]: 25, 51, ♂; Type: ♂, Korea, Ham-Kyong-Duk-Do (=Kankiyo-hokudo) (Mus. Sapporo, lost).

Differential diagnosis. The species is readily distinguished from other species in this genus with tergites 2–4 rugose or granulate by combination of black head and body, red legs (except for coxae) with yellow clypeus.

Material examined. ♀, holotype

Hosts. Pristiphora glauca Benson, 1954 (= Pachynematus laricivous Takagii, 1931 ), Pachynematus nigricorpus Takagi, 1931 .

Remarks. Rhorus takagii is closely related to Euro-Siberian Rh. substitutor (Thunberg, 1824) and quite possibly is junior synonym of this species. However there are some weak features that differentiate Rh. takagii : clypeus yellow in female (in Rh. substitutor clypeus of female blackish with reddish lower 0.3; in male of Rh. substitutor clypeus and face entirely yellow); metapleuron completely rugose (in Rh. substitutor metapleuron smooth and punctate in upper 0.4); fore coxa predominantly reddish yellow, mid coxa completely yellow ventrally (in Rh. substitutor coxae predominantly blackish); recorded hosts of Rh. takagii are Nematinae (Tenthredinidae) (for Rh. substitutor reliable hosts are Diprionidae ). The eastern point of distribution of Rh. substitutor is Krasnoyarsk on the Yenisei river (boundary between West and Central/East Siberia).
