The soapberry bug, Jadera haematoloma (Insecta, Hemiptera, Rhopalidae): First Asian record, with a review of bionomics.

Abstract The soapberry bug, Jadera haematoloma (Herrich-Schäffer, 1847) (Insecta: Hemiptera: Heteroptera: Rhopalidae: Serinethinae), a species native in tropical and subtropical regions of the New World and accidentally introduced to Hawaii, is reported for the first time from Asia (Taiwan). This record represents the first occurrence of the species in Asia. Stable populations composed of hundreds of specimens were found in seven localities of Kaohsiung City and one locality in Tainan City, and a single specimen was observed in Chiayi County. Aggregating adults and larvae fed in large numbers on the sapindacean plants Cardiospermum halicacabum L. and Koelreuteria elegans (Seem.) A. C. Smith ssp. formosana (Hayata) F. G. Meyer. Diagnostic characters of adults and larvae of Jadera haematoloma are discussed. A review of its bionomics and a bibliography are provided. Initial observations on the populations in southern Taiwan are presented. The species is potentially invasive, and further extension of its range is anticipated in Southeast Asia.

Case 3724 — Metochus abbreviatus Scott, 1874 (Insecta, Heteroptera): proposed precedence over Rhyparochromus erosus Walker, 1872 (currently Metochus erosus)

Abstract. The purpose of this application, under Article 23.9.3 of the Code, is to conserve the widely used specific name Metochus abbreviatus Scott, 1874, for a species of rhyparochromid bugs from East Asia. The name is threatened by the senior subjective synonym Rhyparochromus erosus Walker, 1872, which has seldom been used since its first publication. Therefore, precedence of the name Metochus abbreviatus Scott, 1874 over Rhyparochromus erosus Walker, 1872 is proposed.

A revision of Lamprocoris (Hemiptera: Heteroptera: Scutelleridae)

Abstract The genus Lamprocoris Stål, 1865 (Hemiptera: Heteroptera: Scutelleridae: Scutellerinae) is revised. Three species are recognized, treated, and keyed. Lectotypes are designated for Callidea (currently Lamprocoris) roylii Westwood, 1837 and Callidea scripta Walker, 1867. The following new subjective synonyms are proposed: Lamprocoris lateralis (Guérin-Méneville, 1838)  =  L. smaragdus Breddin, 1903, syn. nov.; L. roylii  =  Callidea distinguenda Walker, 1868, syn. nov. Lamprocoris roylii (Westwood, 1837) is recorded for the first time from Burma, Laos, Vietnam and Malaysia, L. spiniger (Dallas, 1849) from Bangladesh and Thailand. A phylogenetic analysis of the included species is provided.

Case 3684. Elasmostethus dorsalis Jakovlev, 1876 (currently Elasmucha dorsalis; Insecta, Heteroptera): proposed precedence over Acanthosoma vicinum Uhler, 1861 (currently Elasmucha vicina).

Abstract. The purpose of this application, under Article 23.9.3 of the Code, is to conserve the widely used specific name Elasmucha dorsalis (Jakovlev, 1876) for a species of subsocial acanthosomatid bug from East Asia. The name is threatened by the senior subjective synonym Elasmucha vicina (Uhler, 1861), which has seldom been used since its first publication. Therefore, precedence of the name Elasmucha dorsalis (Jakovlev, 1876) is proposed.

Case 3523 Callidea lateralis Guérin-Méneville, 1838 (currently Lamprocoris lateralis; Insecta, Heteroptera): proposed conservation of the specific name

Abstract. The purpose of this application, under Article 23.9.3 of the Code, is to conserve the widely used specific name Lamprocoris lateralis (Guérin-Méneville, 1838) for a species of jewel bug from Java by suppressing its objective senior synonym Lamprocoris obtusus (Westwood, 1837). The senior name L. obtusus has never been positively treated as different from L. lateralis but has been neglected in the literature, thereby justifying conservation of Lamprocoris lateralis.
