Remarks. Yasunaga et al. (2018) retained the original generic placement of this taxon in Prolygus ( type species: Lygus papuanus Poppius, 1914 , Fig. 32L–O ). However, the following morphological characters support its proper placement in Paralygocoris , new genus : clavus lacking rows of lines along claval vein ( Fig. 32A, B ); vesica with a single spicule that is coiled subapically and similar in basic colour pattern to P. meridionalis (see Carvalho, 1987 , p. 140, figs. 5–8); female genital chamber narrow ( Fig. 32D ); and posterior wall with small interramal lobe and triangular, mesally continuous lateral lobe ( Fig. 32E, F ). Prolygus congeners share the different character status, such as clavus at least basally with two or three rows of keeled lines parallel to claval vein ( Fig. 32L ); vesica with 2–4 spicule or lobal sclerites ( Fig. 32J, M ); wider genital chamber ( Fig. 32N ); and posterior wall with developed, wide interramal lobe and paired lateral lobes ( Fig. 32K, O ). Based on these evidences, Prolygus alboscutellatus is herein transferred to Paralygocoris , new genus . Both Paralygocoris alboscutellatus and P. meridionalis are considered Sundaland species. However, they appear to be allopatric with each other (the former in Oriental-Wallacea and the latter in continental Eurasia).
