Loristes Josifov & Kerzhner, 1972 View in CoL View at ENA

Loristes Josifov & Kerzhner, 1972: 162 View in CoL (gen. nov.). Type species: Adelphocoris decoratus Reuter, 1908 , original designation.

Loristes: YASUNAGA (1991) View in CoL : 2 (diagnosis); SCHUH (1995): 790 (catalog); KERZHNER & JOSIFOV (1999): 109 (catalog); YASUNAGA (2001): 234 (diagnosis); ZHENG et al. (2004): 304 (diagnosis).

Diagnosis. Recognized by the large, parallel-sided body (7.5-9 mm in length), unique color pattern (dark, shiny body with the three pairs of characteristic, pale, semitransparent spots on the hemelytra, Figs. 1-2, 4-5 View Figs ), shiny dorsum, small eyes, weak transverse basal carina on the vertex, short antenna, incrassate antennal segment II that is subequal in length to the basal pronotal width, short labium that does not exceed the apex of the mesocoxa, impunctate pronotum with dense, pale, semierect setae, thick collar that is about as broad as the diameter of antennal segment II, tumid scutellum, scutellum and hemelytron with uniformly distributed, wooly, reclining setae, and the male and female genitalic structures described below.

Male genitalia ( Figs. 9-16 View Figs ). Male genital segment simple, lacking notable additional structures dorsal to paramere insertions. Parameres with basic shape typical of tribe Mirini ; left paramere long, semi-circularly curved; right paramere short and straight. Vesica with several spiculi and/or lobe-sclerites that are fundamentally homologous within congeners ( Figs. 12, 16 View Figs ); seminal duct slightly expanded apically; phallotheca smooth.

Female genitalia ( Figs. 17-24 View Figs ). Sclerotized ring narrow-rimmed, ovoid; dorsal structure membranous, more or less spinulate; interramal lobe wide, covered with minute spines, not heavily sclerotized.

Distribution. Loristes now comprises two species which inhabit the deciduous forests in the temperate and cold temperate zones of eastern Asia – northeastern China, continental Russian Far East, Japan and Korean Peninsula ( KERZHNER & JOSIFOV 1999, YASUNAGA 2001, ZHENG et al. 2004).

Discussion. Currently, no sister group hypotheses are proposed for Loristes . At first glance this genus appears to be allied to the large Holarctic genus Adelphocoris Reuter, 1896 . However, based on the structures of the antenna, scutellum and male genitalia, this similarity is considered superficial. Loristes is probably most similar in overall appearance to the east Asian Philostephanus Distant, 1904 , but the former genus has no synapomorphy shared by all members of the latter. Philostephanus species have distinctive structures particularly in the female genitalia as documented by YASUNAGA & SCHWARTZ (2007), not known from Loristes . Based on the general shape of the male and female genitalic structures, Loristes is assumed to have some relationship with Polymerias Yasunaga, 1997 (see YASUNAGA 1997).

In a wider geographical scale, Loristes is more or less similar to some genera of Calocoris Fieber, 1858 complex mostly known from the western Palaearctic Region. Higher classification of such superficially similar mirine plant bug genera is still in great need of investigation. Further world level supra-generic revision is required to correctly ascertain these complex groups in the tribe Mirini .
