The number of scale insect species (Hemiptera: Coccoidea) known from Hungary has increased in the last 10 years by 39 (16.6 %), to a total of 274 species belonging to 112 genera in10 families. The family Pseudococcidae is the most species rich, with 101 species in 34 genera; Diaspididae contains 59 species in 27 genera; Coccidae contains 54 species in 27 genera; and the Eriococcidae contains 33 species in 8 genera. The other 6 coccoid families each contain only a few species: Asterolecaniidae (7 species in 3 genera); Ortheziidae (7 species in 4 genera); Margarodidae sensu lato (5 species in 5 genera); Cryptococcidae (3 species in 2 genera); Kermesidae (4 species in 1genus); and Cerococcidae (1 species). Of the species in the check list, 224 were found in outdoor conditions, while 50 species occurred only in indoor conditions. This paper contains 22 species recorded for the first time in the Hungarian fauna.

Surveys of the scale insect (Hemiptera: Coccomorpha) fauna of Greece were carried out in 2013 and 2014. Altogether 93 scale insect species were collected, belonging to 11 families. Thirty-eight species (41%) proved to be new to the Greek fauna, including two species new to science (Anophococcus hellenicus Kaydan & Szita sp. n. (Acanthococcidae) and Iberococcus attikus Szita & Fetykó sp. n. (Pseudococcidae)), and two introduced invasive species (Phenacoccus graminicola Leonardi and Pseudococcus comstocki (Kuwana), both Pseudococcidae). The rest of the species seem to be native to the Greek fauna. The total number of scale insect species recorded from Greece is increased to 253.

The Neotropical scale insect genus Ripersiella Tinsley (Hemiptera: Coccomorpha: Rhizoecidae) was investigated, based on soil samples deposited at the Hungarian Natural History Museum. Description and illustration of a new species, Ripersiella incarum Kaydan & Szita sp. n., and an identification key and new additional locality records for the currently known Ripersiella species in the Neotropical region, are provided and discussed.

Six new species of Newsteadia are described from the Nearctic and Neotropic Regions. A key is presented for the identification of 10 species currently included in the genus from these regions. The number of species in the genus worldwide is 37. A modified concept of the genus is presented and some new characters are given as diagnostic of the genus. The zoogeography of the genus is discussed.

Neotropical species of the scale insect genus Rhizoecus Künckel d’Herculais (Hemiptera: Coccomorpha: Rhizoecidae) found in soil sample material of the Hungarian Natural History Museum were studied. Two new Rhizoecus species, Rhizoecus kontschani Kaydan and Konczné Benedicty sp. n., and Rhizoecus granaradewillinkae Kaydan and Szita sp. n., are described and illustrated based on the adult females. Also, the adult females of Rhizoecus keysensis Hambleton and Rhizoecus pseudocacticans Hambleton are illustrated. An identification key and new additional locality records for the currently known Rhizoecus species are provided.

A study has been conducted to monitor geographical spread of the white peach scale Pseudaulacaspis pentagona (Targioni Tozzetti) (Hemiptera: Diaspididae) (WPS) and its parasitoid populations in 32 stops of the Hungarian highways (M0. M1, M3, M5 and M7) using pheromone traps during 2009 and 2010. In addition to the data collected in the current study, previous data were used to investigate the population trend of this pest from 2007 to 2010. The number of males recorded in traps placed on highways was much lower than in the sites close to urban areas (M0). Our data support results of previous studies which suggest the spreading of white peach scale by vehicles (“transport vector”). The significant decrease in the WPS male catches from 2007 to 2010 might indicate the lowering of the population levels of this pest in the area of the study. Eight hymenopterous parasitoid species were captured in pheromone traps. Coccophagus sp. was the predominate species in pheromone traps of WPS in M7, how-ever they may be associated with another coccid species. The identity of scale males and some parasitoids was proved by molecular markers.

A new genus, Hoyicoccus Williams & Kozár gen. n., and two new species, Hoyicoccus hendersonae Kozár & Williams and Eriococcus szentivanyi Kozár & Williams are described from Sabah, Malaysia. In addition, the genus Sangicoccus Reyne is discussed: Sangicoccus truncatispinus (Reyne) is redescribed and two new species, namely Sangicoccus morrisoni Kozár & Konczné Benedicty and Sangicoccus reynei Kozár & Konczné Benedicty, are described. Sangicoccus is now known off palms from Irian Jaya and Sulawesi in Indonesia, and from the Philippines and Papua New Guinea. A key is provided for the separation of the known species of Sangicoccus.
