RESUMO
The genus Pterinoxylus Serville, 1838 is redescribed and revised at the species level. It is distributed throughout most of Central America, the northern half of South America and also has one species on the Lesser Antilles. Detailed descriptions, notes on intraspecific variability and illustrations are provided for all six known species. Keys are presented to distinguish males, females and eggs. Two new species are described from Costa Rica: P. cocoense n. sp. from both sexes and the eggs and P. speciosus n. sp. from both sexes. The female of P. perarmatus (Redtenbacher, 1908) is described and illustrated for the first time, as are the eggs of the type-species P. eucnemis Serville, 1838 and P. perarmatus (Redtenbacher, 1908). The external morphology of all species shows considerable intraspecific variability, which is discussed and illustrated. While P. cocoense n. sp. is an endemic and the only stick insects that has so far become known from Cocos Island a small island some 550 km off the Costa Rican Pacific coast, all other species appear to have fairly wide distributional ranges. Maps show the distributions of all six known species. Type-specimens of the two newly described species are deposited in the collections of MNCR-A (Costa Rica) and Zoologisches Museum und Universität, Hamburg, Germany (ZMUH).

The new genus Andeocalynda n. gen. is described and the supposed relationships are discussed. The genus is restricted to the mountainous Andean regions of Ecuador and Colombia. Nine new species are described and illustrated: A. aspericollis n. sp., A. banosense n. sp., A. brevicercata n. sp. and A. lojaense n. sp. from Ecuador based on the males only, A. decorata n. sp., A. mutica n. sp., A. densegranuloa n. sp. and A. tuberculata n. sp. from Ecuador as well as A. putumayoense n. sp. from Colombia based on the male and female. The eggs of the two new Ecuadorian species A. decorata n. sp. and A. tenuis n. sp. are described and illustrated. Two species, previously attributed to other genera are transferred to Andeocalynda n. gen., this is: A. carrikeri (Hebard, 1919) from the genus Bacteria Berthold, 1827 (n. comb.) and A. comis (Bates, 1865) from the genus Clonistria Stål, 1875 (n. comb.). As a result, Andeocalynda n. gen. currently includes eleven known species.

The neotropical genus of stick insects, Phantasca Redtenbacher, 1906, was recently revised by Hennemann et al. (2018). However, the females and eggs of several species remain unknown, including all five species recorded from Brazil. The female and egg of Phantasca phantasma (Westwood, 1859) are here described for the first time, based on material available at the Museu de Zoologia da Universidade de São Paulo, Brazil (MZSP). A set of measurements of males is also given, in addition to the measurements of the holotype presented in Hennemann et al. (2018). This complement to the description of P. phantasma is particularly important because it is the type species of the genus (designated by Zompro, 2001), therefore providing additional grounds for future taxonomic decisions involving Phantasca.

The anareolate New World subfamily Cladomorphinae Bradley & Galil, 1977 is reviewed and keys to the six tribes currently included are presented; these are: Cladomorphini Bradley & Galil, 1977, Cladoxerini Karny, 1923, Cranidiini Günther, 1953, Pterinoxylini n. trib., Hesperophasmatini Bradley & Galil, 1977 and Haplopodini Günther, 1953 rev. stat.. New diagnoses are presented for all these tribes and possible relationships within Cladomorphinae are discusssed. Morphology of the genitalia and egg-structures indicate Cladomorphinae as presently treated to be polyphyletic. Two subordinate groups are recognized within present Cladomorphinae, which differ considerably in numerous morphological characters of the insects and eggs. The first group and here regarded as Cladomorphinae sensu stricto is formed by the mostly South American Cladomorphini + Cranidiini + Cladoxerini, while the second group is formed by the predominantly Caribbean Hesperophasmatini + Pterinoxylini n. trib. + Haplopodini. Members of the first group (= Cladomorphini sensu stricto) share the dorsally carinate basitarsus in which the two dorsal carinae are melted with another, increasingly elongated gonapophyses VIII of females which are noticeably longer than gonapophyses IX and lamellate as well as strongly displaced medioventral carina of the profemora. Cranidiini + Cladomorphini share the strongly elongated and filiform gonapophyses VIII and presence of gonoplacs in the females, specialized poculum of males and presence of a median line in the eggs. Cranidiini differs from all other tribes of Cladomorphinae by the entirely unarmed legs of both sexes, distinctly broadened and leaf-like body and prominent longitudinal keel of the mesosternum of females, prominently enlarged poculum and spinulose phallus of males as well as the conspicuous narrowing of the posteromedian gap of the internal micropylar plate of the eggs and noticeably separated median line. Cladomorphini is characteristic for the specialized vomer and poculum of males and distinct opercular structures of the eggs. Certain representatives of Cladomorphini indicate relationships to the "Phanocles-group" of Diapheromerinae: Diapheromerini, hence Cladomorphini as presently treated may be paraphyletic. The exclusively South American Cladoxerini (= Baculini n. syn.) differs from the other two tribes of Cladomorphinae sensu stricto by the distinctly serrate profemora of both sexes and conspicuously shortened antennae of females, which consist of less than 30 segments and are much shorter than the profemora in females. Genital morphology, such as the elongated gonapophyses VIII and presence of gonoplacs in females, as well as the lamellate medioventral carina of the profemora indicate close relation to Cladomorphini. Cranidiini appears to be the sister-taxon of Cladomorphini + Cladoxerini. The tribe Baculini Günther, 1953 is synonymised with Cladoxerini (n. syn.), on the basis that the type-genera of both tribes are congeneric, with Baculum Saussure, 1861 being a junior synonym of Cladoxerus St. Fargeau & Audinet-Serville, 1827 (n. syn.). The genus Tersomia Kirby, 1904 is removed from Hesperophasmatini and transferred to Cladoxerini. Wattenwylia Toledo Piza, 1938 is removed from Pachymorphinae: Gratidiini and transferred to Cladoxerini. A detailed new diagnosis is presented for Cranidiini along with a detailed differentiation and the tribe is shown to be monotypical, only containing its type-genus Cranidium Westwood, 1843. All Caribbean genera subsequently added to Cranidiini are removed and transferred to Haplopodini rev. stat.. The three tribes Hesperophasmatini + Pterinoxylini n. trib. + Haplopodini rev. stat. are closely related and might form a monophyletic clade within Cladomorphinae sensu lato. They differ from Cladomorphinae sensu stricto by the short gonapophyses VIII and reduced gonoplacs of females, unspecialized poculum of males and lack of a micropylar line in the eggs. Haplopodini Günther, 1953 is re-established (rev. stat.) and comprises almost exclusively Caribbean genera previously placed in Hesperophasmatini by Bradley & Galil (1977) or Cranidiini by Zompro, (2004). Aploploides Rehn & Hebard, 1938, Diapherodes Gray, 1835, Haplopus Burmeister, 1838 and Paracranidium Brock, 1998 were misplaced in Cranidiini and are transferred to Haplopodini. On the basis of numerous morphological characters of the insects and eggs Hesperophasmatini is removed from Pseudophasmatidae: Xerosomatinae and re-transferred to its previous position in the subfamily Cladomorphinae sensu lato. A detailed newdiagnosis of Hesperophasmatini is presented, but is only provisional since the true diversity is as yet only fractionally known. The lack of a gula distinguishes Hesperophasmatini from all other tribes. The genus Laciphorus Redtenbacher, 1908 is removed from Hesperophasmatini and transferred to Diapheromeridae: Diapheromerinae: Diapheromerini. The new tribe Pterinoxylini n. trib. is established to contain only the type-genus Pterinoxylus Audinet-Serville, 1838. It is closely related and perhaps the sister taxon of Hesperophasmatini, with which it shares the presence of rough sensory areas on the probasisternum and profurcasternum. It differs from Hesperophasmatini and Haplopodini by the presence of a tympanal region (= stridulatory organ) in the alae of females and the alveolar eggs, which possess peripheral opercular and polar structures. Haplopodini is likely to be the sister group of Pterinoxylini n. trib. + Hesperophasmatini. The tribe Haplopodini rev. stat. is revised at the species level and comprises eight almost exclusively Caribbean genera, four of which are newly described. All eight genera now contained in Haplopodini are described in detail, differentiated from their closest relatives and their relationships and systematic position within Haplopodini are discussed. Keys and maps showing their distributions are presented along with a discussion of the distributional patterns. Detailed descriptions, differential diagnoses, synonymic listings, illustrations, material listings and measurements are given of all 26 currently known species and subspecies of Haplopodini. Four new genera are described within Haplopodini. The monotypical Apteroplopus n. gen. (type-species: Dyme grosse-tuberculata Brunner v. Wattenwyl, 1907) from Honduras is the only taxon of the tribe represented in Central America. It is only known from the male which differs from all other genera by being entirely apterous. Cephaloplopus n. gen. (type-species: Cephaloplopus pulchellus n. sp.) and Parhaplopus n. gen. (type-species: Haplopus cubensis Saussure, 1868) occur only on Hispaniola and Cuba. Both are closely related to Haplopus Burmeister, 1838 but in addition to having noticeably different eggs, both genera differ from Haplopus in several morphological characters. The monotypical Venupherodes n. gen. (type-species: Platycrana venustula Audinet-Serville, 1838) is endemic to Cuba, and in females being apterous resembles the second exclusively Cuban genus Aploploides Rehn & Hebard, 1938. It however differs from all other members of Haplopodini by the laterally expanded mesonotum of females, which overlaps the mesopleurae, as well as the morphology of the eggs. Two species-groups are recognized within Diapherodes Gray, 1835. The gigantea species-group comprises the species from the Lesser Antilles, which are: D. angulata (Fabricius, 1793), Diapherodes dominicae (Rehn & Hebard, 1938), D. gigantea gigantea (Gmélin, 1789), D. gigantea saintluciae n. ssp. and Diapherodes martinicensis Lelong & Langlois, 2005. The three species of the jamaicensis species-group, which are D. achalus (Rehn, 1904), D. jamaicensis (Drury, 1773) and D. laevicollis Redtenbacher, 1906, are restricted to the two Greater Antillean islands Jamaica and Puerto Rico. Haplopus Burmeister, 1838 is the most widely distributed genus being represented on all islands of the Greater Antilles except Jamaica, and also in the Virgin Islands, Bahamas, Florida Keys, Dry Tortugas and as far southwest as the Cayman Islands and Swan Islands. Nine new species and one new subspecies are described: Cephaloplopus alope n. sp. and Haplopus sobrinus n. sp. from Cuba, Cephaloplopus euchlorus n. sp., Cephaloplopus laetus n. sp., Cephaloplopus pulchellus n. sp., Haplopus brachypterus n. sp., Haplopus intermedius n. sp. and Parhaplopus navarroi n. sp. from Hispaniola, Haplopus woodruffi n. sp. from Cayman Brac (Cayman Islands) and Diapherodes gigantea saintluciae n. ssp. from Saint Lucia. Seven of these are described from both sexes but Cephaloplopus alope n. sp. and Haplopus sobrinus n. sp. are only known from the females and Cephaloplopus laetus n. sp. only from the males. The previously unknown males of Diapherodes angulata (Fabricius, 1793), Diapherodes laevicollis Redtenbacher, 1908, Haplopus bicuspidatus de Haan, 1842 and Parhaplopus cubensis (Saussure, 1868) as well as the previously unknown female of Parhaplopus evadne (Westwood, 1859) n. comb. are described and illustrated for the first time. Descriptions and illustrations of the eggs of eleven species are presented: Cephaloplopus euchlorus n. sp., Cephaloplopus pulchellus n. sp., Diapherodes achalus (Rehn, 1904), Diapherodes dominicae (Rehn & Hebard, 1938), Diapherodes gigantea gigantea (Gmélin, 1789), Diapherodes martinicensis Lelong & Langlois, 2005, Diapherodes jamaicensis (Drury, 1773), Haplopus bicuspidatus de Haan, 1842, Haplopus micropterus St. Fargeau & Audinet-Serville, 1825, Parhaplopus navarroi n. sp. and Venupherodes venustula (Audinet-Seville, 1838) n. comb.. Type specimens of the newly described taxa are deposited in the collections of ANSP, NHMUK, IIBZ, FSCA, MCZC, MNHN and USNM. Six species are transferred to other genera (n. comb.): Bacteria grossetuberculata (Brunner v. Wattenwyl, 1907) to Apteroplopus n. gen. (ABSTRACT TRUNCATED)
