Conle, Goldbachweg 24, 87538 Bolsterlang, Germany; e-mail: [email protected]; Website: www.Phasmatodea.com Introduction The Phasmid fauna of the Neotropical Region is apparently rich but still just fractionally studied. Frequently, new genera and species are discovered in all subregions. The present paper is the second part of an extensive ongoing study of the Neotropical Phasmatodea and describes a new genus and two new species from the subfamily Cladomorphinae. The genus presently includes three known species which are recorded from French Guiana, Bolivia and eastern Peru, but is believed to be distributed all over the Amazon basin. The two new species were discovered whilst working in the collections of the Museum d’Histoire naturelle Paris and the Munich State Zoological Collections (Germany) and were kindly given to the authors on loan for examination and description. Type-material of the third taxon was briefl y examined during visits in the corresponding institutions and from detailed photographs. Type material of the two newly described species is deposited in ZSMC and MNHN.

HT Holotype PT Paratype 2 Cladomorphinae Bradley & Galil, 1977 Günther (1953: 557) established the subfamily Phibalosominae and included four tribes, namely Cladomorphini, Hesperophasmatini, Cranidiini and Cladoxerini. Bradley & Galil (1977: 186) changed the subfamilar name to Cladomorphinae, consequently re-named Günther’s Phibalosomini and Haplopodini into Cladomorphini and Hesperophasmatini, and generally took over this authors arrangement of the tribes. Both treated Cladomorphinae (= Phibalosominae) as a subfamily of Phasmatidae. The tribe Cladomorphini includes most of the subfamily’s continental members and differs from the three other tribes of Cladomorphinae by the medioventral carina of the profemora strongly approaching the anteroventral carina instead of being midways on the ventral surface. Furthermore, it is characteristic for the specializations of the male poculum. Presently the following genera are included in Cladomorphini: Cladomorphus Gray, 1835 (= Phibalosoma Gray, 1835), Jeremiodes, gen. nov., Hirtuleius Stål, 1875, Jeremia Redtenbacher, 1908, Otocrania Redtenbacher, 1908, Otocraniella Zompro, 2004 and Xylodus Saussure, 1859. The here newly described genus is apparently closely related to Jeremia Redtenbacher (see differentiation and table 1 below). Jeremiodes, gen. nov. Type-species: Jeremiodes guianensis, spec. nov., by present designation. Bacteria Redtenbacher, 1908: 415. (in part). – Giglio-Tos, 1910: 42. (in part); Brock, 1998: 48; Otte & Brock, 2003: 74 ff. (in part); 2005: 61. (in part). Description Small to medium sized (body lengths: WW 104.0147.7 mm incl. subgenital plate, MM 60.0-79.4 mm), moderately elongate and slender Cladomorphini. Ocelli lacking in WW, reduced but visible in MM. Body of WW slightly oval in cross-section, cylindrical in MM. WW apterous, MM with fully developed alae (24.239.4 mm) and scale-like tegmina. Complete surface of thorax densely granulose in WW; more minutely and sparingly granulose in MM. Abdomen smooth or very sparingly granulose. Head longer than pronotum, longer than wide, oval; vertex either fl at or very gently rounded, unarmed. Antennae of WW longer than head, proand mesonotum combined, of MM longer than combined length of head and complete thorax. Scapus rectangular, about 1.5 × longer than wide and dorsoventrally compressed. Mesothorax elongate, at least 2 × longer than head and pronotum combined. Meso-, metasternum and sternites II-VII of MM with a more or less distinct, longitudinal median carina; simple in WW. Median segment slightly longer (WW), or about 3 × longer than metanotum in MM. Tegmina of MM oval, slightly convex and indistinctly longer than metanotum. Alae at least covering tergites II-IV; anal region transparent. Abdomen longer than head and complete thorax combined. Abdominal segments II-VII of both sexes distinctly longer than wide and parallel-sided. Sternite VII of WW lacking a praeopercular organ. Tergite IX of MM strongly elongated, of bonelike appearance and at least 2 × longer than anal segment. Anal segment of WW with a fi ne median carina; of MM strongly broadened towards the posterior, transverse. Cerci of WW very small, slender and distinctly tapered towards the apex. Cerci of MM prominent, dorsoventrally fl attened, and broadened towards the apex which is obtuse and angled inward. Vomer elongate, roughly triangular and distinctly pointed apically. Poculum of MM prominent and strongly convex, posterior margin bi-dentate. Gonapophyses of WW fi liform and projecting considerably over the anal segment. Subgenital plate of WW very elongate, lanceolate, pointed apically and projecting over the anal segment by at least the combined length of tergites VIII-X. Legs very slender, elongate and completely destitute of spines or teeth in MM. In WW rather short and stout, with all carinae of the femora and tibiae distinct and more or less elevated or undulate. All carinae unarmed (at best minutely granulose) and 1 or 2 sub-apical teeth on the anteroand posterventral carinae of the mesoand metafemora. Profemora triangular in cross-section; medioventral carina very prominent, ledge-like and strongly approaching anteroventral carina. Mesoand metafemora and tibiae trapezoidal in cross-section, medioventral carina distinct. Basitarsi as long as following three tarsomeres (WW), or distinctly longer than remaining tarsomeres (MM) combined, simple. Dorsal carina of probasitarsus very slightly raised in WW. Eggs unknown. Differentiatial diagnosis. Characterized amongst Cladomorphini by the densely granulose thorax of WW, and prominent, distinctly hook-like and dorsoventrally fl attened cerci of MM. Related to Jeremia Redtenbacher, 1908 (Type-species: Jeremia grossedentata Redtenbacher, 1908), but distinguished by: the more slender body; more elongate and less globose head; densely granulose thorax; lack of distinct spines on the mesoand metapleurae and sterna; lack of dorsal lobes on tergite VII; considerably longer, lanceolate subgenital plate and lack of distinct spines on the me- 3 dioventral carinae of the mesoand metafemora and tibiae. From Hirtuleius Stål, 1875 (Type-species: Hirtuleius laeviceps Stål, 1875) Jeremiodes gen. nov. differs by: the fl at and elongate head; lack of tubercles on the mesoand metanotum; lack of lateral lobes on tergites VI and VII and apically pointed subgenital plate. For a more detailed differentiation between Jeremiodes gen. nov., Jeremia and Hirtuleius see table 1 below. As the males of both Jeremia and Hirtuleius are not known, the distinguishing characters defi ne to females only. Etymology. The generic name “Jeremiodes” mirrors the relation to Jeremia Redtenbacher, 1908. Distribution. So far recorded from French Guiana and the tropical lowland regions of eastern Peru and Bolivia, east of the Andes. Most certainly this genus is distributed in the complete Amazon basin.

Differentiatial diagnosis. The very small size and elongate head clearly distinguish this from the two other species in the genus. MM are very similar to J. bolivianus, spec. nov. but differ by: the much smaller size; plain brownish green mesothorax; more elongate and less globose head and relatively longer alae, which reach as far as to the posterior margin of tergite IV.

MM are distinguished by: the distinctly smaller body and more elongate head of both sexes; relatively longer mesothorax; yellowish brown instead of brown abdomen and reddish brown instead of green tibiae which exhibit some irregular, transverse dark bands. WW differ from J. guianensis, spec. nov. by: the granulose head; slightly more slender mesoand metathorax; fl at, not distinctly raised posterior margin of the mesonotum and lack of a distinct sub-apical spine on the anteroand posteroventral carinae of the mesoand metafemora. Description The following descriptions of the W and M are based on the type-specimens in MCSN and NHMW. The M HT of B. pachycerca is complete except for the terminal four abdominal segments; both metatarsi and apical segments of the left antenna. The W HT B. pichisina lacks the right mid and hind leg, right metatarsus as well as the apices of the antennae and has the gonapophyses broken. WW. Small (body length 104.0 mm excluding subgenital plate) rather slender and apterous, with a very long and lanceolate subgenital plate (23.0 mm). General colouration of body and legs yellowish mid brown, the subgenital plate green. Certainly the specimen is discoloured due to a former preservation in ethanol and is believed to have been greenish when alive. Abdominal segments VI and VII darker brown (caused by preservation). Eyes dark reddish brown, antennae dark brown and becoming black towards apex. Head. Ovoid, elongate, 1.6 × longer than wide, broadest at the eyes and gently narrowing towards the posterior. Vertex very slightly rounded and covered with several acute granules. Eyes of moderate size, circular and strongly convex. Between the eyes with a slightly raised area. Antennae at least as long as head, proand mesonotum combined (apices broken in the HT), antennomeres very short and distinctly decreasing in length towards apices of antennae. Scapus dorsoventrally fl attened, about 1.5 × longer than wide and slightly narrowed towards the base. Pedicellus cylindrical, broader than following antennomeres and about 2 / 3 the length of scapus. Thorax. Pronotum distinctly shorter and slightly narrower than head, about 1.3 × longer than wide, roughly rectangular densely granulose. Longitudinal median line and transverse median depression distinct, the latter slightly curved and almost reaching to lateral margins of segment. Prosternum slightly trapezoidal and densely granulose. Mesothorax elongate, slightly more than 2 × longer than head and pronotum combined, slightly constricted
