Abstract. The giant water bug, Lethocerus indicus (Lepeletier & Serville, 1825), is an aquatic true bug that has been included in the Vietnam Red Data Book since 1992 (“ca-cuong” in Vietnamese, “maeng-da” in Laos and Thailand). This insect also has been listed as an endangered species in Japan, Laos, and South Korea. This study aimed to (1) perform a genetic analysis to determine the species status of various populations of L. indicus in Southeast Asia, and (2) initially survey their distribution in Vietnam and Laos. Four populations were collected: two from the Vientiane Capital and Savannakhet Province areas of Laos, and two from the Vinh Phuc and Long An areas of Vietnam, respectively. Cytochrome oxidase subunit I (COI) fragments longer than 600 bps were amplified by polymerase chain reaction (PCR). Twelve nucleotide polymorphisms were found among these four populations. A maximum likelihood tree based on COI showed that the genetic distances among populations were very small, ranging from 0.2% to 1.1%, and were substantially distant from other populations of Lethocerus. Therefore, they are all considered to be conspecific and to represent L. indicus.

Cuerna yuccae Oman & Beamer, 1944 (Hemiptera: Cicadellidae) is a leafhopper found primarily on Joshua trees, Yucca brevifolia Engelmann (Asparagaceae), but also reported on other species of Yucca (Oman & Beamer 1944, Nielson 1965). Cuerna includes 25 species distributed across North and Central America with most species in the western United States (Krishnankutty et al. 2015). The genus is in the tribe Proconiini in the subfamily Cicadellinae, or sharpshooters, medium to large leafhoppers known for their active and evasive behavior. Female C. yuccae are 7.2–8.0 mm in length, and both sexes are gray or black with yellow spots on the head, pronotum, and scutellum and reddish forewings (Fig. 1, Nielson 1965, Krishnankutty et al. 2015). Yucca brevifolia is an arborescent monocot that can reach 12 m in height and is found at elevations of 600–1500 m in southern Nevada and adjacent southern California, western Arizona, and southwestern Utah (Webber 1953, Benson & Darrow 1981). The plants’ thick, branching stems terminate in rosettes of narrow, 15–35 cm long stiff and pointed leaves (Fig. 1). Adult C. yuccae have been collected across the range of Y. brevifolia from April to October (Nielson 1965), and I have also found adults in southern Nevada during December, February, and March. The life cycle of C. yuccae has not been described. All North American leafhoppers develop through the stages of egg, five nymphal instars, and adult (Oman 1949). Nielson & May (1975) reported the life stages and development times of Cuerna arida

Abstract. Cafius chilensis sp. nov. is described from the Chilean coast. Adults of the new species were collected under seaweed and are similar to those of C. algophilus Broun, 1894 and C. maritimus (Broun, 1880) from the New Zealand coast. Morphological comparison for these three species is presented. A description, SEM and habitus photographs, and illustrations of diagnostic characters of the new species are provided to facilitate identification.

Euxesta sororcula (Wiedemann, 1830), previously known from South and Central America as a pest of sweet corn, is here reported for the first time in the United States, in the state of Texas. Illustrations of and a key to the species of the E. sororcula species group are provided.

Abstract. The bow-legged bug genus Hyalymenus Amyot & Serville, 1843 (Hemiptera: Heteroptera: Coreoidea: Alydidae) includes 20 New World species. Of these, nymphs of only one species, H. tarsatus (Fabricius, 1803), have been described, and the description was restricted to the fifth instar. Nine specimens of H. subinermis Van Duzee, 1923, representing the first through the fifth instars, were collected on two Schinus terebinthifolia Raddi (Anacardiaceae) shrubs from a residential neighborhood (approximately 177,828 m2 surveyed) in Long Beach, California, U.S.A. in June 2021. Several other locations within the city were surveyed (i.e., parks, residential areas, and riparian habitats; approximately 109,177 m2 surveyed, collectively), but this species was not observed on other S. terebinthifolia plants or other plant species in these areas. Here, we give the first California record for H. subinermis, describe the five nymphal instars, provide habitus images of each instar, and discuss the distribution of the species in California, known host plants, and putative ant models that nymphs may mimic.
摘要弓腿虫属Hyalymenus Amyot&Serville，1843（半翅目：异翅目：总科：蚁科）包括20个新世界物种。其中，只有一个物种的若虫，H.tarsatus（Fabricius，1803），已经被描述过，并且描述仅限于五龄。2021年6月，在美国加利福尼亚州长滩的一个住宅区（调查面积约177828平方米）的两个Schinus terebinthifolia Raddi（Anacardiaceae）灌木上采集了9个H.subinermis Van Duzee标本，1923年，代表了第一龄至第五龄。对城市内的其他几个地点进行了调查（即公园、住宅区和河岸栖息地；总共调查了约109177平方米），但在这些地区的其他terebinthifolia植物或其他植物物种上没有观察到该物种。在这里，我们给出了加州首次记录的H.subinermis，描述了五个若虫龄，提供了每个若虫龄的习性图像，并讨论了该物种在加州的分布、已知的寄主植物以及若虫可能模仿的假定蚂蚁模型。
