  • Female genital morphology of Cryptocercus Kyebangensis is described, focusing on the structural features of ovipositors at each developmental stage. Ovipositor valves were the first genital structures to appear in female nymphs. The caudal margin of the 9th sternum was nearly straight in the 1st instars of both sexes, with a slight median notch, but was deeply concave in the female nymphs of the End instar. The 1st valve of ovipositor budded off from membranous fold between the 8th 8nd 9th sternum and a pair of the 2nd valve came from the 9th sternum. Separation of styli occurred in the female nymphs of the 8th or 9th instar. Some parts of the female genitalia were sclerotized after the final molt. Spermathecae were the fork type and leaned a little to the right in the middle line of the genital chamber from ventro-posterior view. The trace sealed with sclerite materials existed on the spermathecal opening. The genital segments (segments Ⅷ, IX, and X) were concealed completely by the 7th tergum and sternum posteriorly expanded. Terminal lobes which exist in the Blattidae were not observed in C. Kyebangensis. Instead, the apicolateral emargination existed on the terminal abdominal segment of C. Kyebangensis females.

  • A sterrhine species, Perixera punctata (Warren) is reported for the first time from Korea. One male and one female were collected from Jeju Island, South Korea. Perixera punctata can be distinguished by the long bipectinate male antennae, the blackish discal dot and a large dark grayish dot on the subcosta of the forewings and a large dark brownish discal dot and blackish undulating postmedial line on the hindwings. In the male genitalia, a long slender valva with two arm-shaped costal processes is a distinguishing character. In the female genitalia, long and medially twisted ductus bursae with a colliculum, and large, ovate corpus bursae with minute dots are distinguishing characters. Diagnosis and description of the species are given with figures of the male and female genitalia.

  • The anatomical variations of the external genitalia including the hymen were observed prospectively in 1,500 female infants born between March, 1992 and July, 1992 at the Taegu Fatima Hospital. Careful inspection of the external genitalia was done within 24 hours after birth, and abnormal findings photographed. Almost all hymenal tissue appeared to be redundant. The hymen was annulus in 89.1 % of patients. Ninteen point nine percent had a central orifice and the remainder a ventral orifice. External ridges, intravaginal ridges, and clefts were present in 71.5 %, 50.7 % and 40.5 %, respectively. Congenital anomalies of the external genitalia were found in 20 patients(1.4 %). There were sixteen cases of hymenal cysts, two hymenal polyps, one imperforate hymen, and one Skene's duct cyst. Seven of the 16 hymenal cysts with stalks were excised and those without stalk were aspirated. Hymenal polyps were excised. Imperforate hymen was incised and drained, and Skene's duct cyst was aspirated successfully. The surgical procedure were done without anesthesia, and the results have been good. In conclusion, routine physical examination of the female newborn infant detects frequent developmental anomalies. The significance of those anomalies will be clarified after longitudinal long-term followup studies.

  • This paper reports four species of Erebidae from the southern part of Korea: two Boletobiinae, Honeyania ragusana (Freyer, 1845), Enispa masuii Sugi, 1982, one Hermininae, Adrapsa ablualis Walker, 1859, and one Arctiinae, Stictane rectilinea (Snellen, 1879). Honeyania ragusana can be distinguished by the following: a blackish dot on the apex of the forewing with strongly curved medial lines, a long slender uncus and a strongly distally bifurcated valva with a large distally expanded costa and a thumb-shaped process of sacculus on the male genitalia as well as a sclerotized antrum, strongly tapered ductus bursae, and large corpus bursae on the female genitalia. Enispa masuii, a lichen feeder, can be distinguished by the whitish medial lines of the grayish fore- and hindwings, and a pair of rounded ball-shaped lamella antevaginalis, long, sclerotized ductus bursae, and pear-shaped corpus bursae without signum of the female genitalia. Adrapsa ablualis can be distinguished by the whitish medial lines of the fore- and hindwings and large medial process of the costa and dentate distal margin of the valva of the male genitalia. Stictane rectilinea can be distinguished by the broad dark grayish medial band of the forewing and the long knife-shaped valva with a strongly hooked process on the distal part of the sacculus of the male genitalia.

  • Herein, we report a new record of Arna bipunctapex (Hampson) and a new species, Euproctis fulvatus sp. nov. in Korea; both are Lymantriine moths. Arna bipunctapex is distinguished by a relatively large wingspan with two black dots and a small dot between these black dots in the apical region of a yellowish forewing. The male genitalia of A. bipunctapex can be distinguished by the lack of a process on the sacculus of valva while the female genitalia can be distinguished by an antrum that is basally flat with two lateral digitate arms. Euproctis fulvatus is distinguished by yellowish wings with a medially curved central fascia of the forewing. The male genitalia can be distinguished by the bifid, digitate uncus and the simple, square-shaped valva with a distal strong invaginated margin. The female genitalia can be distinguished by the long, medially twisted, ductus dursae with simple antrum posteriorly strongly sclerotized and ovate corpus bursae without signum. Larvae of E. fulvatus are distinguished by a black head with a pair of long, black, lateral tufts, dorsum with 10-11 white intersegmental dots and bright red setal warts on T2-A8, and bright red glands on A6 and A7.

  • Two species of Phycitinae, Rabiria rufimaculella (Yamanaka, 1993) and Copamyntis martimella Kirpichnikova & Yamanaka, 2002, are reported for the first time from Korea. Rabiria rufimaculella can be recognized by having two reddish-yellow and short bands near the postmedial and antemedial line, and by the bifurcate gnathos and the cornutus which is formed by numerous thorn-shaped sclerites in male genitalia. Copamyntis martimella can be distinguished with the congeners by the uniformly distributed setae on the sacculus and the curved aedeagus in male genitalia and the peanut-shaped signum near the middle of the corpus bursae in female genitalia. The adults and genitalia of the species are redescribed and illustrated.

  • Male pseudohermaphrodites is one of abnormalities of phenotypic sex and have an XY chromosome constitution and testes, but the internal or external genitalia are to some degree those of a female. We surveyed one case which were referred in Veterinary Medical Teaching Hospital of Seoul National University. When patient was purchased, its phenotype was entirely female that have female external genitalia. However, from the age of 6 months, clitoris was gradually increased to Os clitoris, and patients showed male behavior. Critical clinical sign was trauma of protruded Os clitoris. In radiographic and ultrasonographic examination, he had normal vagina and urinary bladder. In chromosome examination, he had an XY chromosome constitution. This case was performed removal of Os clitoris and ovariohysterectomy.

  • In Korea, 104 species of Notodontidae have been recorded. The genus Odontosia H$\ddot{u}$bner is characterized by the elongate and serrate margin of its forewing and the prominent harpe of valva and many spinular cornuti on the vesica of the male genitalia and the robust ductus bursae and large, ovate and sclerotized corpus bursae of the female genitalia. Only one species of Odontosia, O. patricia Stichel, 1918, has been reported from Korea. In this paper, Odontosia sieversii ($M\acute{e}n\acute{e}tri\grave{e}s$, 1856) is newly added to the Korean fauna based on three male specimens collected at Mt. Bangtaesan, Gangwon-do, Korea. Diagnosis for the species and photographs of adult and genitalia of the genus Odontosia are provided.
