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.

A New Species

A checklist of the genus Platycerus Geoffroy is updated. A method for the observation of endophallus is introduced and used for the study of four species of Platycerus from China. The morphology of Chinese species of Platycerus is reviewed, and all the useful morphological characters are clarified. A character matrix is made to accumulate all the current information on morphology of Chinese species. Platycerus yingqii sp. nov. is described from the northern slope of Mount Taibaishan, southern Shaanxi, China. This new species is similar to Platycerus rugosus, but can be distinguished by male with a browner dorsal surface, remarkably shorter tarsi, lighter and redder ventrites, shorter gap between incisor teeth and mola, male genitalia with different endophallus, female with shorter metatarsi, and female genitalia with the inner apex of hemisternite not protruding beyond the outer apex. The morphological characters of the other three species from China are also studied. A key to the geographical species groups of Platycerus is presented. Keys to the Chinese species are provided for both males and females. Finally some natural history notes are given for some species of Platycerus from China.

A New Species

We describe a new species of Selvasaura from the montane forests of the eastern slopes of the Andes in northern Peru, based on external and hemipenial morphological characters and previous phylogenetic analyses. The new species can be differentiated from the other two Selvasaura species in having keeled dorsal scales usually flanked by longitudinal striations, in adults and juveniles; adult males with a yellow vertebral stripe bordered by broad dark brown stripes on each side and a unilobed hemipenis surrounded by the branches of the sulcus spermaticus. The description of the new species contributes information about new states of diagnostic characters of Selvasaura and natural history.

Details of egg, larval, and pupal morphology are described and illustrated for Calycopis bellera (Hewitson) and C. janeirica (Felder), with a special emphasis on larval chaetotaxy. Wild-caught Calycopis females laid eggs on dead leaves in the laboratory, and the caterpillars successfully completed development on an artificial agar diet to which no leaves were added. Males and females of the sexually dimorphic C. bellera had been previously placed in different genera or different species groups. Calycopis janeirica had been chronically misidentified (and misspelled C. jeneirica). Males and females of this species appear to be correctly associated for the first time. Whereas C. bellera has five larval instars—as reported previously for C. caulonia—C. janeirica has four. Morphological characters of the immatures of C. bellera and C. janeirica are summarized in a table and compared with those of other reared Calycopis species.

Abstract The Chinese Panorpa species without anal horn are normally assigned to the Panorpa davidi group. Here, we taxonomically revise the P. davidi group, which currently includes 17 known species and four new species: P. gaokaii sp. nov., P. huayuani sp. nov., P. uncinata sp. nov. and P. yaoluopingensis sp. nov. Panorpa shanyangensis Chou & Wang, 1981 and P. sexspinosa zhongnanensis Chou & Ran, 1981 are treated as junior synonyms of P. sexspinosa Cheng, 1949. We describe for the first time the male of P. stigmosa Zhou, 2006, and the females of P. curva Carpenter, 1938, P. davidi Navás, 1908, P. difficilis Carpenter, 1938, P. fructa Cheng, 1949, and P. jinchuana Hua, Sun & Li, 2001. A key to species of the group is provided. Phylogenetic analyses of maximum parsimony and maximum likelihood based on 79 morphological characters show that the newly defined P. davidi group is a well-supported monophyletic group and is sister to the genus Cerapanorpa Gao, Ma & Hua, 2016.

We describe eight new species of the genus Pholcus, and document their microhabitats. Four species are assigned to the previously described Pholcus ethagala group: P. tanahrata Huber sp. nov., P. uludong Huber sp. nov., and P. bukittimah Huber sp. nov. from the Malay Peninsula, and P. barisan Huber sp. nov. from Sumatra. These species are all litter-dwellers that build domed sheet webs on the undersides of large dead leaves on the ground. The other four species are assigned to newly created species groups: the P. tambunan group with two species from northern Borneo: P. tambunan Huber sp. nov. and P. bario Huber sp. nov.; and the P. domingo group with two species from the Philippines, Mindanao: P. domingo Huber sp. nov. and P. matutum Huber sp. nov. These latter four species are leaf-dwellers that build barely visible silk platforms tightly attached to the undersides of live leaves. The main rationale for this paper is to provide part of the taxonomic and natural history background for upcoming phylogenetic and evolutionary (microhabitat shifts) analyses.

This paper provides a taxonomic revision of the Neotropical ant genus Hylomyrma Forel (1912) (Myrmicinae: Pogonomyrmecini). Morphological traits combined with geographical data and natural history information led to the recognition of 30 species, fourteen of them described here as new: Hylomyrma adelae sp. n., Hylomyrma dandarae sp. n., Hylomyrma jeronimae sp. n., Hylomyrma lispectorae sp. n., Hylomyrma lopesi sp. n., Hylomyrma macielae sp. n., Hylomyrma margaridae sp. n., Hylomyrma mariae sp. n., Hylomyrma marielleae sp. n., Hylomyrma mitiae sp. n., Hylomyrma peetersi sp. n., Hylomyrma primavesi sp. n., Hylomyrma virginiae sp. n. and Hylomyrma wachiperi sp. n. Lectotypes for H. speciosa (junior synonym of H. balzani) and H. reitteri are here designated from syntypes to improve nomenclatural stability. Except for the three species most recently described (H. montana, H. plumosa, and H. villemantae), the external morphology of workers is described or redescribed, as well as for the known males and queens, most described here for the first time. Of the 30 recognized species herein, 11 present intercastes; at least three of them present female specimens with queen-like traits that may be understood as ergatoids. An updated identification key for Hylomyrma workers is provided, as well as high resolution photographs of all known sexes and castes, species distribution maps, and a summary of what is known from the biology of all species.

The tarantula genus Lyrognathus Pocock 1895 is revised with three new species described: L. achilles sp. nov. from Gunung Nibung, Borneo; L. fuscus sp. nov. from Simpang Kubur, Borneo and L. lessunda sp. nov. from Lombok Island, Indonesia. The male of L. robustus Smith 1988 is described for the first time, the female is redescribed. L. crotalus Pocock 1895 is considered a senior synonym of L. pugnax Pocock 1900. Several new characters are discussed, with Lyrognathus keyed to species. The diagnosis of the Selenocosmiinae is amended. Zoogeographic distribution, natural history and subfamilial relationships with proposed sister genera Selenocosmia Ausserer 1871 and Coremiocnemis Simon 1892 are discussed. Lyrognathus saltator is redescribed. Selenocosmia lyra Strand 1913 is considered a nomen dubium.

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.

Simulium (Hearlea) Vargas, Mart nez Palacios, & D az N jera 1957 is comprised of 20 known species that are largely confined to the area between M xico and Guatemala. Herein, all currently recognized species within this subgenus are described, illustrated, keyed (except males), and subjected to phylogenetic analysis. Geographic distributions for each species are also updated. Simulium deleoni Vargas, 1945, is synonymized with S. capricorne De Le n, 1944. Simulium paracarolinae new species, from Guatemala, is described from the larva. A cladistic analysis of all Hearlea species and representatives from three outgroups was conducted using 39 morphological characters. Although different character weighting methods yielded different topologies, all trees agreed that Hearlea is monophyletic is comprised of two species groups, based mainly upon characters of the larva and pupa: the Simulium juarezi group S. ayrozai Vargas, S. burchi Dalmat, S. canadense Hearle, S. capricorne De Le n, S. chiriquiense Field, S. contrerense D az N jera & Vulcano, S. dalmati Vargas & D az N jera, S. delatorrei Dalmat, S. estevezi Vargas, S. ethelae Dalmat, S. juarezi Vargas & D az N jera, S. microbranchium Dalmat, and S. nigricorne Dalmat and the S. carolinae group Simulium (Hearlea) carolinae De Le n, S. gorirossiae Vargas & D az N jera, S. johnsoni Vargas & D az N jera, S. larvispinosum De Le n, S. menchacai Vargas & D az N jera, S. paracarolinae n. sp., and S. temascalense D az N jera & Vulcano.
