We revise the Neotropical snail-feeding Charadrella and add two new species to it, one from Bolivia and one from Brazil. Additionally, we perform a cladistic analysis of the genus, based on morphological characters. Parsimony analyses were carried out under equal and implied weights. Our matrix included 25 species from nine Neotropical and three Afrotropical genera, including the snail-feeding Cariocamyia Snyder (Neotropical), Aethiopomyia Malloch, Alluaudinella Giglio-Tos and Ochromusca Bigot (Afrotropical). The following relationships between the species of Charadrella were recovered: (C. albuquerquei (C. macrosoma (C. malacophaga (C. boliviana, sp. nov., C. nambikwara, sp. nov.)))). In our chosen topology, the clade that includes Charadrella has the following topology (Dichaetomyia (Alluaudinella (Ochromusca (Itatingamyia (Cariocamyia, Charadrella))))), supporting the placement of the genus in the Dichaetomyiinae.

Phylogenetic Revision

The tribe Dacini comprising four genera, namely Bactrocera Macquart, Dacus Fabricius, Monacrostichus Bezzi and Zeugodacus Hendel, is a derived lineage in Tephritidae. It is one of the most economically important tribes in Tephritidae harbouring several species of quarantine concern across the world. We describe two new species of Bactrocera Macquart, B. (Parazeugodacus) conica David & Ramani, sp. n. & B. (B.) prabhui David, sp. n. from India. Postabdominal structures of males and/or females of 23 species of Bactrocera, 16 species of Zeugodacus and 8 species of Dacus from India are illustrated and described for the first time, which revealed similarities between Dacus and Zeugodacus with respect to epandrial shape and praeputium patterning. Bactrocera is unique in possessing oval shaped epandrium and an unpatterned praeputium. An analysis of phylogenetic relationships between three genera of the tribe Dacini from India based on morphological characters has been attempted for the first time. Cladistic analysis employing 51 characters of 62 species in Dacini, with seven species as outgroups revealed the monophyly of Dacini, Bactrocera and Dacus with supporting nonhomplasious synapomorphies. Ichneumonopsis Hardy, often included in the Gastrozonini, does not possess any synapomorphies of Dacini, eventhough it appeared at the base of the Dacini clade. Zeugodacus was retrieved as a monophyletic sister-group to Dacus based solely on a single homoplasious host plant character, with weak statistcal support.

Two New Species

In this paper, the monophyly of the genus Thoreyella Spinola was tested, and a hypothesis of relationships among its species is proposed. Four known species of Thoreyella and two new species, as well as species of three other genera of Procleticini (Neoderoploa Pennington, Lobepomis Berg, and Procleticus Berg), were treated as the ingroup. The new species of Thoreyella will be published elsewhere. Two species of Dendrocoris were used for outgroup comparison. A cladistic analysis of 38 morphological characters supported a hypothesis of common ancestry for Thoreyella and the three genera of Procleticini included in the ingroup. The results also showed Thoreyella as a monophyletic taxon, and its sister group relationship with the monophyletic group including Neoderoploa, Lobepomis, and Procleticus. The geographical distribution of these taxa is discussed.

High Degree

A cladistic analysis of the species of Calloserica Brenske, 1894, was executed using 49 morphological characters of adults. The generated phylogenetic tree supports the monophyly of the genus and the sister-group relationship between Pachyserica and (Gastroserica, Neoserica). Allopatric speciation is discussed as an important mechanism for explaining present tree topology and distribution patterns. Emergence of adults (and mating) during the monsoon season is considered to be a major factor for stimulating the diversification of this group, resulting in its highly restricted distribution and a high degree of endemism. Two new species are described from Nepal: Calloserica capillata, sp. nov. and C. manangensis, sp. nov.

Two new species of Biguembia Szumik (B. mirador n. sp. and B. troncol n. sp.) and one new species of Gibocercus Szumik (G. podamita n. sp.) from Brazil are described and illustrated. The female of Gibocercus chaco Szumik is described for the first time. Female terminalia of both genera are redefined and redescribed for B. copo, G. chaco and G. beni. Additionally, a cladistic analysis using almost 100 morphological characters was developed. Both genera appear monophyletic and well supported by several synapomorphies. The results also indicate that some species are unjustified and therefore they are synonymized: Gibocercus magnus Ross, 2001 = Gibocercus beni Szumik, 1997; Gibocercus flavipes Ross, 2001 = Gibocercus nanai Szumik, 1997; Gibocercus napoa Ross, 2001 = Gibocercus sandrae Ross, 2001, all new synonymies. The relationships of the new species are discussed as well as the potentiality of female traits.

Two new species, Flavoperla retusata Mo, Li & Wang, sp. nov. and F. yangi Mo, Li & Murányi, sp. nov. are proposed from the Guangxi Zhuang Autonomous Region of southern China. Distinctness of the new species is based on morphological characters and DNA sequence comparisons with their closest known relative, F. galerispina Mo, Wang & Li, 2020. The taxonomic relationships of the two new species and related congeners are discussed.

The study is based on new material from the collections of the Naturalis Biodiversity Centre in Leiden (RNHM) and the Hungarian Natural History Museum (HNHM) and addresses issues in two genera: Epeus Peckham & Peckham, 1886 and Ptocasius Simon, 1885 from Thailand. Both genera are of Asian/Indomalayan origin, the latter with a diversity hotspot in the subtropical valleys of the Himalayas. Based on morphological data, we propose three new species of Epeus (Epeus daiqini sp. nov. (♂♀), Epeus pallidus sp. nov. (♀), Epeus szirakii sp. nov. (♀)) and two new species of Ptacasius (Ptocasius metzneri sp. nov. (♂♀) and Ptocasius sakaerat sp. nov. (♀)). Additionally, we redescribed E. tener (Simon, 1877) and added photographs of morphological characters. The genus Ptocasius is redefined due to the inclusion of 37 species, previously included in Yaginumaella Prószyński, 1979. Relationships and distribution of both genera are discussed in reference to molecular, morphological and distributional data, published by other authors in recent years.

Two new species of the damselfly genus Euphaea Selys, 1840 (Odonata: Euphaeidae) are described from the Western Ghats of Satara District, Maharashtra, distinguished by their distinct morphology and coloration. E. thosegharensis Sadasivan & Bhakare sp. nov. is similar to E. cardinalis (Fraser, 1924), but is distinguished by the extensor and flexor surface of all femora black while all femora bright red in E. cardinalis; apical fourth of Hw black while apical half of Hw black in E. cardinalis; genae reddish-orange, black in E. cardinalis; a tuft of sparse stub black hair on either side of tergite of S9 while both S8 and S9 with tufts of long ventral hairs in E. cardinalis.  Male genital vesicle matt black, with distal border rounded angles, while vesicle black and hexagonal in shape with rounded angles in E. cardinalis and S9 twice the length of S10, while S9 and S10 of equal length in E. cardinalis. E. pseudodispar Sadasivan & Bhakare sp. nov., is very close to E. dispar (Rambur, 1842), but is differentiated easily by the absence of yellow patch on legs as in E. dispar; only apical fifth of Hw black; genae being yellowish-white, while black in E. dispar; male genital vesicle brownish-black & rhomboid-shaped and with no transverse rugosities while black with distal border rounded and with fine transverse rugosities in E. dispar; penis with single seta on each side while E. dispar has three pairs; sternite of S9 very prominently extending ventrally like a beak in comparison with E. dispar.  We have identified additional morphological characters useful in taxonomy of Euphaea of the Western Ghats for example, tufts of ventral hairs on terminal abdominal segments genital vesicle, penile structure of males and sternite of S9 in the males, and vulvar scales of females.  A taxonomic key to all known species of genus Euphaea of the Western Ghats is also provided.

Taxonomic Changes

An integrative taxonomy approach was implemented based on analysis of genetic, phylogenetic, morphological and ecological data to identify the cryptic diversity within the Phyllodactylus lanei complex. At least six species can be identified, of which four are currently considered subspecies: Phyllodactylus lanei, Phyllodactylus rupinus, Phyllodactylus isabelae, Phyllodactylus lupitae and two corresponding to undescribed taxa, which are identified and described in this contribution. These differ from other Mexican geckos in several characters: genetic distance (DNAmt), position in molecular phylogeny (concatened data DNAmt+DNAnu), species tree, morphological characters such as snout-vent length, longitudinal scales, tubercles from head to tail, interorbital scales, scales across venter, third labial–snout scales and rows of tubercles across dorsum; there are also differences in their bioclimatic profiles (temperature and precipitation) and geographical distribution. The most recent studies on taxonomy and evolution of Mexican geckos (Phyllodactylus) show that the diversity of this group of reptiles is currently underestimated, suggesting that more research and conservation efforts are should be addressed at these lizards.

Two new species of the weevil genus Rhamphus from Italy are herein described: R. bavierai n. sp. (Sicily) and R. hampsicora n. sp. (Sardinia). Both are morphologically and from a molecular perspective close to R. oxyacanthae (Marsham, 1802) and R. monzinii Pesarini & Diotti, 2012. Aside from a diagnostic description and a synoptic key, distribution data and notes on the host plants of the four species are reported. Whereas R. monzinii can be distinguished by several morphological characters, the other three species are morphologically very similar to each other and separable only by the combination of a few subtle characters. On the contrary, a preliminary molecular study revealed substantial divergences of mtCOI from 6.2 to 14.9% between the species, confirming the importance of an integrative taxonomy.
