Two new species, Stericta jaeshini Kim & Bae, sp. nov. and S. atroaurantiaca Kim & Bae, sp. nov. are described from Laos and Cambodia. About 50 species of the genus Stericta have been recorded from Southeast Asia, but it has not been recorded to occur in Laos and Cambodia previously. We record the presence of this genus in these two countries for the first time in this study. Illustrations of adults and genitalia of examined species are provided.

캄보디아와 라오스에는 지금까지 가루깍지벌레과 25종 및 18종이 각각 보고되어 있다. 2015년 이들 지역에서 가루깍지벌레과14종이 채집 되었으며, 그 중 캄보디아에서 2종[Antonina graminis (Maskell, 1897), Coccidohystrix insolita (Green, 1908)], 라오스에서 5종[Nipaecoccus viridis (Newstead, 1894), Paracoccus marginatus Williams & Granara de Willink, 1992, Phenacoccus solani (Ferris, 1918), Rastrococcus iceryoides (Green, 1908)]을 처음으로 보고한다.

Coccoidea (scale insects and mealybugs) are some of the most potentially detrimental pests for agriculture and ornamental plant industries in worldwide and the same in Cambodia and Laos. Scale insects were collected on branches, leaves, peduncles, petioles and fruits of hosts in January to July, 2015 and February, 2016. Previously, Coccoidea fauna of Cambodia and Laos comprise 41 and 35 species respectively. Recently we collected 25 species belong to 3 families of Coccoidea. Among these, nine species are first found in these countries; [Coccidae] Ceroplastes ceriferus (Fabricius, 1798) in Laos, Ceroplastes stellifer (Westwood 1871) in Cambodia, Milviscutulus mangiferae (Green, 1904) in Laos and Cambodia, [Pseudococcidae] Kiritshenkella sacchari (Green, 1900), Phenacoccus parvus (Morrison, 1924 ) in Laos, Palmicultor lumpurensis (Takahashi, 1951) in Cambodia, Rastrococcus invadens (Williams,1986) in Cambodia and Laos, [Diaspididae] Aulacaspis tubercularis (Newstead, 1906) in Cambodia, Aonidiella aurantii (Maskell, 1879) in Laos and Cambodia.

Previously study of mealybug faunas of Cambodia and Laos were known to comprise 25 species and 18 species, respectively. Recently, we have collected fourteen mealybug species in Cambodia and Laos from June to July, 2015. Among them, six species are first found in these countries: Coccidohystrix insolita (Green) in Cambodia; and Antonina graminis (Maskell) in both countries; Nipaecoccus viridis (Newstead), Paracoccus marginatus (Williams & Granara de Willink) Phenacoccus solani (Firris) and Rastrococcus iceryoides (Green) in Laos.

가루깍지벌레는 열대지역에서 일반적인 해충으로 관상식물과 과수류의 큰 문제를 일으키는 해충이다. 캄보디아와 라오스에는 현재 가루깍지벌레과 22종 및 12종이 각각 보고되어 있다. 최근 이들 지역에서 가루깍지벌레과 연구를 수행하여 13종이 채집되었으며, 그 중 캄보디아에서 3종인 Dysmicoccus neobrevipes (Beardsley, 1959), Phenacoccus solani (Ferris, 1918), Rastrococcus iceryoides (Green, 1908) 와 라오스에서 6종인 Dysmicoccus neobrevipes (Beardsley, 1959), Paracoccus invectus (Williams, 2004), Phenacoccus solenopsis (Tinsley, 1898), Planococcus litchi (Cox, 1989), Planococcus minor (Maskell, 1897), Pseudococcus jackbeardsleyi (Gimpel & Miller, 1996)가 이들 국가로부터 처음 보고된다.

The family Pseudococcidae or mealybugs (Hemiptera) are common pests in tropical region of the world and also considered as important pests on ornamental plants and fruit trees. The mealybug faunas in Cambodia and Laos were known to nineteen species and eight species, respectively (ScaleNet, 2014; CABI, 2015; FAO-IPM, 2014). Recently, we have collected thirteen mealybug species in Cambodia and Laos. Among them, seven species of mealybug are found for the first time: Phenacoccus solani (Ferris, 1918) and Rastrococcus iceryoides (Green, 1908) in Cambodia; Dysmicoccus neobrevipes (Beardsley, 1959) and Phenacoccus solenopsis (Tinsley, 1898) in both counties; Paracoccus invectus (Williams, 2004), Planococcus minor (Maskell, 1897) and Pseudococcus jackbeardsleyi (Gimpel & Miller, 1996) in Laos.

The stingless bees are restricted to the tropical regions of the world and are considered as important pollinators of various wild and cultivated plants. In the recent investigation, fourteen species of stingless bees are recognized in the dry season from Cambodia and Laos, which are congeners to the species from adjoining country Thailand. In this study, four species in each country Cambodia and Laos are found for the first time: Lisotrigona cacciae (Nurse, 1907), Pariotrigona pendleburyi (Schwarz, 1939), Tetragonula sirindhornae (Michener and Boongird, 2004) and Tetrigona melanoleuca (Cockerell, 1929) from Cambodia, and Homotrigona anamitica (Friese, 1909), Lepidotrigona flavibasis (Cockerell, 1929), Lisotrigona furva Engel, 2000 and Tetragonula fuscobalteata (Cameron, 1908) from Laos. Morphological images, identifying key to genus and species, discussion on the various types of nest and biology for each species are provided.
