12 E. Kondorosy work, the study of Geocorinae specimens from the Oriental region made the following changes necessary. SYSTEMATIC PART Geocoris rutiloides DISTANT, 1918 is proposed as a junior subjective synonym of Geocoris jucundus (FIEBER, 1861) (described as Ophthalmicus jucunclus). The holotype of Geocoris rutiloides is identical with specimens identified as Geocoris jucundus. Holotype of the latter has probably been lost. Geocoris vestitus DISTANT, 1901 is proposed as a junior subjective synonym of Geocoris jucundus (FIEBER, 1861) (described as Ophthalmicus jucundus). The holotype of Geocoris vestitus shows great similarity to G. jucundus, although the yellow spot on the head is larger (head is yellow along inner margin of eyes, too). This is, however, not a species-level difference, therefore both species should be regarded conspecific. Geocoris puri DISTANT, 1910 also resembles Geocoris jucundus (FIEBER, 1861), but the fore margin of pronotum is dark, and posterior half of scutellum is yellow. This difference probably does not exceed specific level, but pubescence is absent, too. Therefore, the synonymy is suspected, but further investigation is needed. Geocoris walked LETHIERRY et SEVERIN, 1894 is proposed as a junior subjective synonym of Geocoris ornatus (FIEBER, 1861) (described as Ophthalmicus ornatus); the only difference between their holotypes is that the head and dark spot of pronotum of Geocoris ornatus are darker brown. DISTANT (1904) treated Geocoris walkeri as identical with Geocoris ornatus (without formal synonymization), but neither SLATER (1964) nor SLATER & O'DONNELL (1995) reported it. Geocoris elegantulus DISTANT, 1904 (and some other Australian species) are closely related with Geocoris ornatus, but they are probably not identical. Geocoris rufipennis DISTANT, 1918 is proposed as a junior subjective synonym of Geocoris ochropterus (FIEBER, 1844) (described as Ophthalmicus ochropterus). The holotype is very similar in shape to G. ochropterus, but it is bright red in colour, while light parts of the latter are yellowish or ochraceous (sometimes head of Geocoris ochropterus is reddish). Geocoris varipes DISTANT, 1918 (page 190) is proposed as a junior subjective synonym of Geocoris erebus DISTANT, 1918 (page 189). The author can not find any significant difference between the two species. Geocoris kalighatus DISTANT, 1910 is proposed as a junior subjective synonym of Geocoris hirsutus MONTANDON, 1907. There are only little differences
