A new species of Erythrogonia Melichar, 1926 (Insecta: Hemiptera: Cicadellidae: Cicadellini) from the Mantiqueira mountain range, southeastern Brazil, associated with olive orchards

A new species of the diverse Neotropical sharpshooter genus Erythrogonia Melichar, 1926 is described and illustrated from the Mantiqueira mountain range, municipality of Maria da Fé, state of Minas Gerais, southeastern Brazil. The new taxon is associated with olive orchards and has been implicated as a vector of the bacterium Xylella fastidiosa Wells et al., 1987, which causes a disease known in Brazil as olive leaf scorch syndrome. Erythrogonia sinvali sp. nov. can be distinguished from the other 90 known species of the genus by the following combination of features: (1) crown black without conspicuous contrasting spots; (2) frons with large yellow median spot; (3) pronotum black with large yellow area covering most of disk; (4) forewing dark red, without contrasting spots or stripes, costal margin narrowly black, apical portion dark brown; (5) aedeagus elongate, curved dorsally, with pair of spiniform apical processes; (6) paraphyses greatly reduced; (7) basal portion of male anal tube with pair of spiniform curved processes; (8) posterior margin of female abdominal sternite VII broadly emarginate and with broad central lobe; (9) female sternite VIII with sclerotized areas, including a transverse bar located at bases of ovipositor valvulae I, followed by a pair of elongate sclerites and a posterior bilobed sclerite. Both males and females of the new species are described in detail. A putative group of five species within Erythrogonia is preliminarily proposed, including the new taxon, E. separata Melichar, 1926, E. dorsalis (Signoret, 1853), E. calva (Taschenberg, 1884), and E. melichari Schmidt, 1928. Among these species, the male terminalia of E. sinvali sp. nov. are more similar to those of E. separata.

A new species of Sternitta Fibiger, 2011 (Lepidoptera, Erebidae, Hypenodinae, Micronoctuini) from Cambodia

Fibiger (2011) established the genus Sternitta in the Micronoctuidae, with Sternitta gregerseni Fibiger, 2011 from Nepal as the type species. The Micronoctuidae are currently treated as a tribe (Micronoctuini) within the Hypenodinae, and include over 400 described species. To date, the genus Sternitta (Micronoctuini: Micronoctuina) consists of seven species: S. goateri Fibiger, 2011 in Afghanistan; S. hackeri Fibiger, 2011 and S. gabori Fibiger, 2011 in Pakistan; S. parasuffuscalis Fibiger, 2011, S. suffuscalis (Swinhoe, 1886), S. gabori Fibiger, 2011 and S. magna Fibiger, 2011 in India; S. suffuscalis (Swinhoe, 1886) in Sri Lanka and S. gregerseni Fibiger, 2011 only in Nepal (Swinhoe 1886; Fibiger 2011). The genus Sternitta was considered by Fibiger to be among the more primitive micronoctuine genera, and it can be recognized by the sclerotized 8th abdominal sternite with prominent dorsal and ventral processes and, in the male genitalia of most species, by the divided ampulla into dorsal and ventral plates and by the dorsal spinelike processes on the anellus. In the present paper, the new species Sternitta mondulkiriensis sp. n. is described from Cambodia with habitus and male genitalia illustrated and compared with those of S. suffuscalis (Swinhoe, 1886). An updated checklist and a key to all the species are included.

Two new species of Megarthrus (Coleoptera, Staphylinidae, Proteininae) from Mexican Cloud Forests

Two new species of Megarthrus are described from cloud forests of the Mexican state of Veracruz: M. cavianae Rodríguez, Navarrete-Heredia & Arriaga-Varela sp. nov., and Chiapas: M. chiapas Cuccodoro sp. nov. They differ from the two hitherto known Mexican species M. altivagans Bernhauer, 1929, and M. alatorreorum Rodríguez & Navarrete-Heredia, 2015, both from temperate forests of the Transmexican Volcanic Belt, by having synapomorphic features of the M. inaequalis-supergroup of species. This lineage includes all the Central and South American members of the genus, with the inclusion of these species, the distribution of the group is extend by more than 5 degree of latitude to the North. Within this lineage, the two new species share a very peculiar morphology of the male abdominal sternite VIII found elsewhere in the genus only in M. flavosignatus Bierig, 1940, and M. zunilensis Sharp, 1887, with which they form the M. zunilensis-group of species defined here.

New species and new distributional records of Elanela Rolston, 1980 (Heteroptera: Pentatomidae)

Two new species are described, Elanela colombiana sp. nov. from Colombia, with disk of scutellum callused, ivory and abdominal sternite VIII immaculate medially, and Elanela ecuatoriana sp. nov., from Ecuador, distinguished by legs with black spots and the dorsal rim and ventral rim of pygophore with a medial process. Illustrations of habitus and genitalia of each species are provided and the distributional map was updated to include the new species and a new record of E. jordi. Additionally, the identification key to the species of Elanela is updated to include the new species.

Description of a new species of the Lissochlora albociliaria species group (Lepidoptera: Geometridae, Geometrinae)

The genus Lissochlora was described by Warren (1900) and revised by Pitkin (1993) with respect to the fauna of Costa Rica. Lissochlora has a small spur or kink to its aedeagus and is distinguished from related genera by the absence of basal costal process of the valva in the male genitalia, which is present in Nemoria Hübner, Rhodochlora Warren and Paromphacodes Warren (Pitkin 1993, 1996). Paromphacodes, Lissochlora and Nemoria cluster together, sharing a bilobed eighth sternite and the presence of a costal sclerite or ornamentation on the valva (Viidalepp 2017). Usually species of Lissochlora have a shorter uncus in the male genitalia than that of related genera, and the last abdominal sternite of the male is usually shorter than the corresponding tergite (Viidalepp 2017).

Sinopyrophorinae, a new subfamily of Elateridae (Coleoptera, Elateroidea) with the first record of a luminous click beetle in Asia and evidence for multiple origins of bioluminescence in Elateridae

The new subfamily Sinopyrophorinae within Elateridae is proposed to accommodate a bioluminescent species, Sinopyrophorusschimmeli Bi & Li, gen. et sp. nov., recently discovered in Yunnan, China. This lineage is morphologically distinguished from other click-beetle subfamilies by the strongly protruding frontoclypeal region, which is longitudinally carinate medially, the pretarsal claws without basal setae, the hind wing venation with a well-defined wedge cell, the abdomen with seven (male) or six (female) ventrites, the large luminous organ on the abdominal sternite II, and the male genitalia with median lobe much shorter than parameres, and parameres arcuate, with the inner margin near its apical third dentate. Molecular phylogeny based on the combined 14 mitochondrial and two nuclear genes supports the placement of this taxon far from other luminescent click-beetle groups, which provides additional evidence for the multiple origin of bioluminescence in Elateridae. Illustrations of habitus and main diagnostic features of S.schimmeli Bi & Li, gen. et sp. nov. are provided, as well as the brief description of its luminescent behavior.

A taxonomic study on Themus (Telephorops) davidis species-group (Coleoptera, Cantharidae), with description of a new species from China

Themus (Telephorops) davidis species-group is redefined and we present a catalogue, identification key and distribution map for this group. Some previously known species are redescribed and we provide new illustrations of female internal genitalia, abdominal sternite VIII and/or aedeagus. Further, we report new distribution data. A new species, Themus (Telephorops) hainanus sp. nov. from China (Hainan) is described, and Themus (Telephorops) birmanicus Wittmer, 1983 is recorded from China for the first time.

Discovery of the genus Pseudepione Inoue, 1943 in Taiwan, with description of a new species (Lepidoptera: Geometridae: Ennominae)

The genus Pseudepione Inoue, 1943 is a small geometrid taxon comprising only two species, the typo species P. magnaria (Wileman, 1911) and P. shiraii Inoue, 1943. They are known to distribute in Japan (Honshu, Kyushu and Shikoku), south and central Korea (Choi 2012; Choi & An 2010; Jung & Oh 2012), the former species was also reported in Jiangxi of China (Fang 2003). The genus seems to be univoltine since adults can only be found in the autumn season (Wileman 1911; Inoue 1943, 1982; Parsons et al. 1999; Kim & Beljaev 2001; Sato 2011; Choi 2012). The combination of the absence of forewing fovea, tuft of scales of third abdominal sternite, gnathos, socii and cormata is quite unique in Ennominae. So far, the phylogenetic affinity of Pseudepione is unclear since the closely related genus has never been proposed and still no morphological or molecular phylogenetic studies, i.e. Beljaev (2006a; 2006b; 2016), Sihvonen (2011), Yamamoto & Sota (2007), Jiang et al. (2017), considering the palaearctic subfamily or tribal levels sampled this genus. The dense fundamental surveys conducted in recent 7 years in the cloud forests of Taiwan acquire the opportunity to collect this genus new to Taiwan. After comparing the Taiwanese specimens with the known two species in both sexes, it’s clear the Taiwanese specimens are a distinct species needed to be described in the present study.

A contribution to the knowledge of Themus (Haplothemus) Wittmer from China (Coleoptera: Cantharidae)

The Chinese fauna of Themus Motschulsky, 1858 is studied. Two new species are described: Themus (Haplothemus) quadratiformis sp. nov. (China: Shaanxi) and T. (H.) longideverticulum sp. nov. (China: Yunnan). Themus (Haplothemus) mishmiensis Wittmer, 1973 stat. nov. is elevated to the full-species rank from the subspecies of T. (H.) elongatior Pic, 1955, both species are redescribed. The male of T. (H.) quadratus Wittmer, 1983 and the female of T. (H.) weishanensis Kopetz, 2016 are described for the first time. The species are illustrated with aedeagus and habitus of male, abdominal sternite VIII and internal genitalia of female.

New species and new records of Calycomyza Hendel (Diptera: Agromyzidae) in Brazil

Two new species and a new record of Calycomyza Hendel are described for the Brazilian Amazon: Calycomyza rolandrae sp. nov. and Calycomyza dryas sp. nov. This is the first time we recorded Calycomyza hyptisicola Spencer and Calycomyza richardsi (Spencer) in Brazil. These species can be distinguished by the structure of the male terminalia, but the female terminalia can be an important taxonomic character, especially the ninth abdominal sternite, ninth abdominal tergite and the marginal seta.
