Adult females of pupillarial species of armored scales(Hemiptera: Coccoidea: Diaspididae) do not produce a typical waxy cover for protection. Instead they remain completely or partially enclosed in the shed skin of the enlarged, second instar nymph. Worldwide, there are 62 genera of armored scales that have pupillarial species. They occur in several diaspid tribes; all species in the tribes Fioriniini and Leucaspidini, and the subtribes Xerophilaspidina of the Diaspidini, Gymnaspidina of the Parlatorini, and Aonidiina of the Aspidiotini (Howell and Tippins, 1990). The first record of a pupillarial form of armored scale insect in Korea is that of the Japanese maple scale, Lopholeucaspis japonica (Cockerell) which Paik (1978) accredited to Machida and Aoyama (1930) firstly documented. Until now, additional species of pupillarial genera of armored scale insects have not been reported in Korea, although surveys have been conducted in Korea.
Two pupillarial forms collected during the survey of armored scale insects occurring on coniferous trees that was conducted in Jeollanamdo (Southern area of Korea) from 2006 through 2010 were identified as Cryptoparlatorea leucaspis Lindinger and Fiorinia japonica Kuwana. These represent the first records of the occurrence of these species in Korea.
Currently, the genus Cryptoparlatorea contains only two species C. pini Takahashi that occurs on pines in India and C.leucaspis Lindinger, found during this survey, which was previously known only from Japan on several evergreen species. The other genus Fiorinia contains 67 species worldwide and among them, the coniferous fiorinia scale, Fiorinia japonica Kuwana newly added to the catalogue of Korean scale insects has been already known from neighboring countries, China and Japan (Kuwana, 1925a; Tao, 1999).
When it comes to the economic importance of pupillarial forms, F. japonica is considered to be a serious pest of pine trees in Beijing, China and an occasional pest in USA (Tang, 1984; Miller and Davidson, 1990), however, during the recent survey, I did not observe this scale to be causing serious damage to the Korean pine trees. According to literatures (Kuwana, 1926; Kawai, 1980), C. leucaspis is not a major pest in Japan and it did not seem to be causing damage to Japanese cedars (Cryptomeria japonica) growing in Korea.
A key, brief account and photographs of the pupillarial species of armored scales in Korea including two species newly documented in this paper, are provided to assist in their identification. Terminology for morphological structures used in this paper is that of Miller and Davidson (2005). An asterisk(*) is used to indicate a new distribution record. Photographs were taken using AxioCam MRc camera through ZEISS Axio Imager M2 Microscope and a LEICA M165C microscope with Delta pix camera. All specimens for accurate identification were mounted on slide and are deposited in the Collection of Yeongnam Regional Office, Animal, Plant and Fisheries Quarantine and Inspection Agency (QIA) in Busan, Korea.
Genus Cryptoparlatorea Lindinger, 1905 검은점깍지 벌레속(신칭)
Cryptoparlatorea Lindinger, 1905. Type species: Cryptoparlatorea leucaspis Lindinger.
Characters
Characters. This genus is placed between Leucaspis and Parlatoria and the general characters of the female scale and pygidium of female body are similar to those of the former, while the shape of the marginal gland orifices is similar to those of the latter. Female scale oval to elliptical with slightly lateral constriction on each side, convex, black. The adult female enclosed in the second larval shed skin. Pygidial lobes small and conical projections. Pygidial plates fimbriate and exceeding the lobes. The male scale elongate, white, not carinated (Kuwana, 1926; Takagi, 1960).

Field Characters
Field Characters. Female scale shiny black with reddish margin, oval to elliptical in shape, composed of the first and second larval shed skin as well as wax mass. First exuviae present margin. 1-1.5 mm long and 0.4-0.5 mm wide. Male scale elongate, white, not carinated, about 1 mm long (Kuwana, 1926).
Slide-mounted Characters
Slide-mounted Characters. Body shape of adult female oval and unsclerotized except for pygidium and medial area. Pygidium of adult female with 3 pairs of well-developed lobes, all similar in shape, small, conical; median lobes parallel, widely separated; 2nd lobes, about same size as median lobes; 3rdd lobes, smaller than median lobes. Plates fimbriate; two between median lobes; two between median and 2nd lobes; three between 2nd and 3rd lobes; three laterad of 3rd lobes. Macroducts short and large; 1 marginal macroduct each between median lobes, median and 2nd lobes, 2nd and 3rd lobes; 1-2 macroducts laterad of 3rd lobes. Perivulvar pores in 4 groups, about 20 pores on each side of body. Cephalothorax and prepygidial area of abdomen with intermittent row of tubercular gland spines along the lateral margin. Anterior spiracles each with 2-3 pores, posterior spiracles without pores. Antennae set apart, each with 1 seta.
