Perdita subgenus Heteroperdita Timberlake, a distinctive subgenus of 22 species from the southwestern United States and adjacent Mexico, all specialists on Tiquilia (Boraginaceae), is revised. Nine new species are described: Perdita (Heteroperdita) desdemona Portman, sp. n., P. (H.) exusta Portman & Griswold, sp. n., P. (H.) hippolyta Portman & Griswold, sp. n. (male previously incorrectly described as P. pilonotata Timberlake), P. (H.) hooki Portman & Neff, sp. n., P. (H.) nuttalliae Portman, sp. n., P. (H.) prodigiosa Portman & Griswold, sp. n., P. (H.) sycorax Portman, sp. n., P. (H.) titania Portman & Griswold, sp. n., and P. (H.) yanegai Portman, sp. n. The following sexes are associated and described for the first time: the male of P. (H.) frontalis Timberlake, 1968, the female of P. (H.) optiva Timberlake, 1954, and the true male of P. (H.) pilonotata Timberlake, 1980. Perdita (H.) fasciatella Timberlake, 1980 is proposed as a junior synonym of P. (H.) sexfasciata Timberlake, 1954. A neotype is designated for P. (H.) pilonotata Timberlake, 1980. Two species in particular, P. prodigiosa and P. pilonotata, are sexually dimorphic with distinctive ant-like males. Information is presented on floral relationships, phenology, and geographic distribution. Identification keys for males and females are provided.

The ant genus Prionopelta Mayr, 1866 is revised for the Neotropics. Morphological traits combined with geographical data led to the recognition of eight species, four of them described here as new: Prionopelta dubia sp. n., Prionopelta menininha sp. n., Prionopelta minuta sp. n., and Prionopelta tapatia sp. n. Prionopelta marthae Forel, 1909 is proposed as a new junior synonym of Prionopelta antillana Forel, 1909. External morphological descriptions of the worker caste for all species are provided, as well as for some of the males and queens, mostly described here for the first time. Identification keys for all known castes, distribution maps and high-resolution illustrations are supplied for all species.

A New Species

A new species of apoid wasps, Pseudoplisus willcoxi sp. nov., is described from Arizona, New Mexico, and Colorado. It is compared with all other species currently assigned to the genus. It has a remarkable overall color pattern, unique in Pseudoplisus, and a restricted collecting record: only a single specimen was collected outside of the Willcox area in Arizona (defined here as including the Animas area, New Mexico). Additionally, of the 34 remaining specimens, one was collected in 1974 and all other after 2001. In the present paper, the new species is diagnosed, described, and the relevant characters are illustrated. The geographic distribution and its heterogeneous collecting record are briefly discussed.

Within the scorpion genus Vaejovis C.L. Koch, the “mexicanus” group is composed of species distributed in the mountains of México. This group presents taxonomic problems, because its characterization and the species included in the group have varied through the years. In the present work, we redefine this group based on several morphological characters, and we differentiate it from the other two species groups within the genus: “vorhiesi” and “nit dulus+nigrescens”. Additionally, five new species are described: Vaejovis ceboruco sp. nov., Vaejovis nanchititla sp. nov., Vaejovis santibagnezi sp. nov., Vaejovis talpa sp. nov. and Vaejovis tapalpa sp. nov; the males of three species are described for the first time (V. dugesi, V. nigrofemoratus and V. tesselatus); and the updated diagnosis for all species is included. Keys for the identification of males and females of the 30 species included in this group are given. Lastly, notes on the natural history and distribution of some species are provided, with maps of known distribution for all the species.

Umbyquyra gen. nov., a new Theraphosinae genus with stridulatory bristles on the palpal trocanther of pedipalp trochanter and first leg, is proposed. The genus differs from the other genera with stridulatory bristles on the same segments, Acanthoscurria Ausserer, 1871, Cyrtopholis Simon, 1892, Longilyra Gabriel, 2014 and Nesipelma Schmidt & Kovarik, 1996, by having a palpal bulb with a very short and acuminate embolus and four short keels; separated tibial apophysis; and female spermathecae resembling those of Cyrtopholis, with two seminal receptacles with elongated ducts emerging from a common area. Cyrtopholis palmarum Schiapelli & Gerschman, 1945 and C. schmidti Rudloff, 1996 from Brazil and Acanthoscurria acuminata Schmidt & Tesmoingt in Schmidt, 2005 from Bolivia are transferred to the new genus. The female of Umbyquyra palmarum (Schiapelli & Gerschman, 1945) gen. et comb. nov. and the male of U. schmidti (Rudloff, 1996) gen. et comb. nov. are described for the first time. Cyrtopholis zorodes Mello-Leitão, 1923 is considered a junior synonym of Acanthoscurria gomesiana Mello-Leitão, 1923 and Cyrtopholis meridionalis (Keyserling, 1891) is considered a nomen dubium. Eight new species from Brazil are described: Umbyquyra paranaiba gen. et sp. nov., U. cuiaba gen. et sp. nov., U. araguaia gen. et sp. nov., U. sapezal gen. et sp. nov., U. belterra gen. et sp. nov., U. caxiuana gen. et sp. nov., U. tucurui gen. et sp. nov. and U. tapajos gen. et sp. nov. Data and maps on the geographic distribution are provided.

The Afrotropical representatives of the hover fly genus Mesembrius Rondani, 1857 (Diptera) are divided into two subgenera, namely Mesembrius s.s. and Vadonimyia Séguy, 1951 and, in this present work, the subgenus Mesembrius s.s. is revised. A total of 23 Mesembrius s.s. species are recognised for the Afrotropics. Known species are re-described and six species new to science are described: Mesembrius arcuatussp. nov., M. copelandisp. nov., M. longipilosussp. nov., M. sulcussp. nov., M. tibialissp. nov. and M. vockerothisp. nov. Mesembrius africanus (Verrall, 1898) is considered a junior synonym of M. senegalensis (Macquart, 1842), M. ctenifer Hull, 1941 a junior synonym of M. caffer (Loew, 1858), M. lagopus (Loew, 1869) a junior synonym of M. capensis (Macquart, 1842) and M. platytarsis Curran, 1929 a junior synonym of M. simplicipes Curran, 1929. The females of Mesembrius chapini Curran, 1939, M. rex Curran, 1927 and M. regulus (Hull, 1937) are described for the first time. Lectotypes are designated for Mesembrius caffer, M. capensis, M. cyanipennis (Bezzi, 1915), M. minor (Bezzi, 1915), M. senegalensis, M. strigilatus (Bezzi, 1912) and M. tarsatus (Bigot, 1883). Separate identification keys for males and females are presented. We obtained 236 DNA barcodes for 18 species. The relationships amongst the different Mesembrius species are briefly discussed, based on morphological and DNA barcode data.

The genus Teleogryllus is known from 52 species distributed worldwide, of which India is home to 11 species. We update Teleogryllus diversity by describing a new species, T. rohinae Jaiswara & Jain sp. nov., from Kerala, India. In addition, we revise the description of the two widespread Teleogryllus species, i.e., T. mitratus (Burmeister, 1838) and T. occipitalis (Serville, 1838) and describe their female genital structures for the first time. Finally, we provide updated identification keys for all Indian Teleogryllus species.

Meromacrus is a genus of conspicuous syrphids with saprophagous larvae, ranging from the southern United States to Argentina and Chile. However, this genus is in need of a taxonomic revision. Adults reared from larvae collected in Mexico and Peru, and other material available at different institutional collections were examined. Meromacrus cactorum sp. nov., from Peru, Meromacrus yucatense sp. nov., from Mexico, their puparia and breeding sites were described. A key to Meromacrus puparia is provided. The holotypes of Meromacrus canusium, Meromacrus gloriosus, Meromacrus laconicus and Meromacrus melmoth were also examined. The name Meromacrus draco is proposed as a junior synonym of M. gloriosus. Larvae of M. cactorum sp. nov. were found in decaying columnar cacti in Peru, while those of M. yucatense sp. nov. in a rot-hole of a Ceiba pentandra stump. Obtained results on both taxonomy and biology of these species serve as a first step towards a revision of the entire genus.
