**New cave species of Cyphoderus Nicolet and Pararrhopalites Bonet & Tellez (Hexapoda, Collembola) from Caatinga biome, Brazil**

PAOLLA GABRYELLE CAVALCANTE DE SOUZA — 2024-06-27

In recent years, surveys have revealed a high diversity of troglophilic and troglobitic species of Brazilian Collembola, mainly represented by the Entomobryidae and Sminthuridae, which hold some representative genera in Brazilian caves such as Cyphoderus Nicolet and Pararrhopalites Bonet & Tellez. Here we describe in detail two new species of these genera sampled from caves of the semiarid region of Rio Grande do Norte state, Brazil. Cyphoderus caatinguensis sp. nov. is similar to other Neotropical species of the tridenticulati group, but it is unique by the combination of labial chaetotaxy, ungues with a filamentous apical tooth and number of feathered chaetae on the dorsal face of the dens. Pararrhopalites iataganii sp. nov. differs from other Neotropical species of the genus especially by the number of subsegments of the fourth antennomere, number of cephalic spines, manubrium chaetotaxy and ventral dens formula. Recognition of these species enhances our understanding of the subterranean fauna in the Neotropics, and their identification may support future conservation policies for caves of the Rio Grande do Norte state, Brazil.

**Morphology and molecular evidence reveal hidden diversity among snapping shrimp of the Alpheus obesomanus group (Decapoda: Alpheidae) with the description of a new species from Brazil**

PATRICIA S. SANTOS — 2024-06-27

The snapping shrimp family Alpheidae Rafinesque, 1815 includes numerous species, most of which present controversial geographical distributions. The disjunct distribution of Alpheus simus Guérin-Méneville, 1856 in the western Atlantic, from Florida to the south of the Caribbean Sea and then from Rio Grande do Norte to Bahia in Brazil, suggests that Brazilian material may belong to an undescribed species. The examination of specimens previously identified as A. simus revealed the distinct morphology of material from Brazil, resulting in the description of a new species based on morphological and molecular evidence. The specimens were collected from fragments of fire coral at the Parque Municipal Marinho do Recife de Fora, Porto Seguro, Bahia, Brazil. Alpheus coralvivo sp. nov. belongs to the A. obesomanus group and is morphologically similar to A. simus (northwestern Atlantic) and A. saxidomus Holthuis, 1980 (eastern Pacific), differing mainly in the stylocerite and scaphocerite lengths and in the large gap between the cephalothorax and pleuron of the first pleonal segment. Molecular analysis using the mitochondrial cytochrome oxidase subunit I gene support the existence of the new species.

**Five new species of the genus Phlugiolopsis (Orthoptera: Tettigoniidae: Meconematinae) from Yunnan, China**

YANGYANG PAN — 2024-06-27

In this paper we described five new species in the genus Phlugiolopsis from Yunnan Province. P. heterotrullis, P. cryphiconica sp. nov., P. puerensis sp. nov., P. platicercis sp. nov., P. minoriproceris sp. nov. One new synonym is proposed, Phlugiolopsis clavata syn. nov. with Phlugiolopsis tridigitis Pan & Bian, 2024. Other species in the genus are commented on and illustrated: Phlugiolopsis trullis Bian, Shi & Chang, 2012, P. huangi Bian, Shi & Chang, 2012.

**Review of bamboo-feeding leafhoppers of the genus Mukaria (Hemiptera: Cicadellidae: Deltocephalinae) in China, with description two new species**

YONG-TAO ZHAO — 2024-06-27

Two new species, Mukaria creagra Zhao, Luo & Chen sp. nov. and Mukaria striola Zhao, Luo & Chen sp. nov., of the bamboo-feeding leafhopper genus Mukaria Distant, 1908 are described and illustrated form Guizhou and Yunnan, China. Three species moved from Mukaria Distant, 1908 into Mukariella Viraktamath & Webb, 2019. A key for all known Chinese species of Mukaria and Mukariella is given.

**Description of the female of P. pauferrense Rodrigues, Cizauskas & Rheims, 2018 and three new species of Paracymbiomma Rodrigues, Cizauskas & Rheims, 2018 (Araneae: Prodidomidae) from Brazil**

IGOR CIZAUSKAS — 2024-06-27

In this paper, we describe three new species of Paracymbiomma Rodrigues, Cizauskas & Rheims, 2018 and the female of P. pauferrense Rodrigues, Cizauskas & Rheims, 2018. Two species are restricted to the iron caves of the Carajás Speleological Unit, in the state of Pará, Brazil: Paracymbiomma pepita sp. nov. (male, female), from Serra Leste, Curionópolis and P. otxurucu sp. nov. (male, female) from Serra Sul, Canaã dos Carajás and Parauapebas. Paracymbiomma una sp. nov. (male, female) is described from Reserva Biológica do Una, Una, Bahia, Brazil. In addition, we list additional material collected in caves and deposited in arachnological collections in Brazil, provide an identification key and updated distribution map for all known species of the genus.
