Immature stages and new host plant records for eight euptychiine butterflies in southeastern Peru (Lepidoptera: Nymphalidae: Satyrinae: Satyrini)

Tue, 13 Jan 2026 00:00:00 +1300

We here report the immature stages and novel host plant records for six species in the nymphalid subtribe Euptychiina, which are documented based on populations found in the Madre de Dios department, Peru: Caeruleuptychia urania (Butler, 1867), Harjesia blanda (Möschler, 1876), Deltaya ocypete (Butler, 1867), Yphthimoides renata (Stoll, 1780), Cisandina philippa (Butler, 1867), Cisandina castanya Lamas & Nakahara, 2022. We also report new host plant records for two euptychiine species: Magneuptychia libye (Linnaeus, 1767) and Modestia harpyia (C. Felder & R. Felder, 1867). A total of eight euptychiine species are discussed in the present study and the majority of new host plant records for them belong to the family Poaceae except for M. harpyia which was found feeding on seedlings of Euterpe precatoria (Arecaceae). We provide photos of documented immature stages and host plants for species discussed herein, as well as DNA barcode data for selected taxa.

**New or rare Madagascar tiger beetles—27. Pogonostoma (Pogonostoma) andasibense sp. nov., and a revised key to the Pogonostoma (P.) elegans species-group (Coleoptera: Cicindelidae)**

JIŘÍ MORAVEC, JÜRGEN WIESNER — Tue, 13 Jan 2026 00:00:00 +1300

A new species of the genus Pogonostoma Klug, 1835, P. (Pogonostoma) andasibense sp. nov. is described from Analamazaotra (= Andasibe-Mantadia) National Park in eastern Madagascar. This new species is placed here into the Pogonostoma (s. str.) elegans species-group, established by Rivalier (1970) as modified by Moravec (2007) and here. A revised key to species of the species-group is presented in order to supplement the key by Moravec (2007) and Moravec & Vybíral (2020). The new species is compared to other similar taxa with references to the illustrations of their type and other specimens in the monograph by Moravec (2007). Habitus and diagnostic characters of the new species are illustrated in colour photographs. The history of the protected area of the type locality is discussed according to the recent status of the Analamazaotra National Park. A map of distribution of the new species and a map showing protected areas of Madagascar are also presented.

**First records of the genus Macrobathra Meyrick, 1883 (Lepidoptera: Cosmopterigidae) from Taiwan, with description of a new species and two newly recorded species**

YI-YANG LU, JIA-YUAN LIANG, YU-FENG HSU — Tue, 13 Jan 2026 00:00:00 +1300

Macrobathra Meyrick, 1883 is a cosmopterigid genus, comprising over 130 species. The present study documents the genus in Taiwan for the first time with two newly recorded species, M. flavidus Qian & Liu, 1997 and M. latipterophora Li & Wang, 2004, and a new species, M. basilutea Lu, Liang & Hsu, sp. nov., is described herein. Images of adults and genitalia of both sexes are provided for the new species, along with a key to the Macrobathra species from Taiwan. DNA barcodes of the three species are provided. A host plant of M. latipterophora, Quercus pachyloma, is also recorded for the first time. Sexual dimorphism is described in M. basilutea sp. nov..

Gypona nigronervosa Stål (Hemiptera: Cicadellidae: Gyponini): redescription of male, first description of female, new synonymy, color polymorphism, and new records

ALEXANDRE CRUZ DOMAHOVSKI, ANDRESSA PALADINI — Tue, 13 Jan 2026 00:00:00 +1300

Based on the study of the holotypes of Gypona nigronervosa Stål, 1854 and Gypona validana DeLong, 1980, along with 80 additional specimens from Brazil, it is proposed that G. validana is a junior synonym of G. nigronervosa. A detailed redescription and illustrations of the male are provided, as well as the first description of the female and new distribution records. Additionally, a discussion on sexual color dimorphism and male color polymorphism in Gyponini is presented.

**A new species of the subterranean genus Troglocyphoniscus Strouhal, 1939 (Isopoda: Oniscidea: Trichoniscidae) from the Tara Mountain, Serbia**

IVO KARAMAN, MLADEN HORVATOVIĆ — Tue, 13 Jan 2026 00:00:00 +1300

Troglocyphoniscus tarae sp. nov. was described from the Medveđa jama cave on Tara Mountain in Serbia as the fourth species in this subterranean genus. The diagnostic characteristics and affinity of the new species and genus are discussed. The distribution of the closely related troglobite genera Troglocyphoniscus and Graeconiscus is presented and discussed in the light of Mediterranean geotectonic events.

JOHN SKARTVEIT — Tue, 13 Jan 2026 00:00:00 +1300

The genus Cascoplecia Poinar, 2010 from mid-Cretaceous Myanmar amber is revised, and two new species described. Cascoplecia tridens sp. nov. is described from a female specimen, whereas C. gracilis sp. nov. is described from a male specimen, the first male Cascoplecia known.

**Description of Protosticta hopkinsi sp. nov. from the Bidoup Nui Ba National Park, the Central Highlands of Vietnam (Odonata: Zygoptera: Platystictidae)**

QUOC TOAN PHAN, NGUYEN THI PHUONG MAI, LE VAN SON — Tue, 13 Jan 2026 00:00:00 +1300

Protosticta hopkinsi sp. nov. is described from the Central Highlands of Vietnam (Holotype ♂: Vietnam, Lam Dong Province, Lac Duong District, Thien Thai waterfall, 12.14472°N, 108.52944°E, alt. 1,559 m a.s.l., 29 April 2025, Zoological Collection of Duy Tan University). The new species can be easily distinguished from all other species in the Protosticta trilobata group by the combination of the yellow stripe on dorsal synthorax of male and female, and the shape of the apical part of the paraprocts.

**First description of the male Megalogomphus flavicolor (Fraser, 1923) from the fringe of Raimona National Park, Assam, India (Odonata: Gomphidae)**

Tue, 13 Jan 2026 00:00:00 +1300

Megalogomphus flavicolor (Fraser, 1923) was described based on a female specimen from Bihar. To date, no formal description has been available for the male. The present communication deals with the first description of the previously unknown male of M. flavicolor, along with the supplementary notes on the morphology of female, based on a male and a female specimen collected from the fringe area of Raimona National Park in Assam, Northeast India. The present record also designates the first record of M. flavicolor for the northeast Indian state Assam, representing easternmost distributional range of the species.

Neohyalinocerus Zhang gen. nov., is described to accommodate Amritodus flavoscutatus Cai & Shen, 1998, resulting in the new combination Neohyalinocerus flavoscutatus (Cai & Shen). The genus is characterized by the presence of some transverse rugae on the head and pronotum, and presence of a ventral process on the male pygofer.
