Zwei neue Stabschrecken von den Philippinen (Phasmatodea).
Abstract
Two new species of Phasmatodea (Manduria halconensis n. sp. and Baculolonga philippinica n. gen., n. sp.) from the Philippine Island of Mindoro are described and figured including a description and illustration of the egg of Manduria halconensis n. sp. Manduria halconensis differs from the only known member of the genus M. systropedon (Westwood, 1859) by the body being stouter, the legs shorter with the mesofemora bearing leaf-like lobes and the different structure of the body granulation.
The new genus Baculolonga n. gen. is erected with Cladoxerus serratipes Gray, 1835 as type species. The genus is easily distinguished from Pharnacia Stål, 1877 and Phobaeticus Brunner v. W. by the morphology of the eggs. Additionally, it differs from Pharnacia by being more slender in both sexes and the slightly longer median segment of the females and from Phobaeticus by the winged males (except philippinica n. sp.) and the much longer median segment. The egg of B. serratipes (Gray) is illustrated. Baculolonga philippinica n. sp. is similar to the three other members of the new genus, B. serratipes (Gray, 1835), B. kirbyi (Brunner v. W., 1907) and B. redtenbacheri (Dohrn, 1910), but can be easily distinguished from these by the males being completely wingless. The egg of the new species is still unknown, while the eggs of the other three species have previously been described by other authors.
... et sp. n., Mount Halcon on the eastern half of Mindoro island, represents the third highest mountain in the Philippines, but so far is known to harbour only few other phasmatodean taxa, specifically: four members of Lonchodinae: [11,[20][21][22]. Most of these species appear to be Mindoro endemic, and future studies on this locality will certainly raise the number of taxa represented. ...
Based on characters of both sexes, a new genus and species of the basal euphasmatodean lineage Aschiphasmatidae is described and figured from the Philippines. Dallaiphasma eximius gen. et sp. n. displays interesting features for the group, including: a cone-shaped vertex, which is notably raised above the pronotum; the tibial area apicalis represented by a depressed membranous posterior lateral region, and a strongly sclerotized central apical region; the euplantulae consisting of smooth-type attachment pads; the pretarsal claws pectination reduced to minute denticulations; and the well-differentiated boundary between the metanotum and the first abdominal tergum. The phylogenetic information content of the new findings is discussed. Furthermore, as a result of this study, the Aschiphasmatidae are newly recorded from Mindoro island, and now include five genera and six species of the Philippines.
The subfamily Lonchodinae is a large but still rather poorly studied group of Old World Phasmatodea. The collections of the authors include numerous species of Lonchodinae from the Philippine Islands of Samar, Mindoro, Panay, Babuyan and Luzon, some of which are here studied in detail. Two new genera and eleven new species are described. Keys to the genera and a checklist of Philiippine Lonchodinae are presented which lists 28 described species in nine distinct genera.
The genus Mithrenes Stål, 1877 is re-described and distinguished from related genera. Two new species are described based on both sexes and the eggs: Mithrenes mindorensis sp. n. from Mindoro and Mithrenes panayensis sp. n. from Panay. A lectotype is designated for Mithrenes asperulus Stål, 1877. The paralectotype of Lonchodes systropedon Westwood, 1859 is conspecific with Mithrenes whiteheadi (Kirby, 1896) and Lonchodes nodulosus Brunner v. Wattenwyl, 1907 is the opposite sex and a junior synonym as is Dixippus bilobatus Brunner v. Wattenwyl, 1907 (syn. n.). A lectotype is designated for Dixippus bilobatus Brunner v. Wattenwyl, 1907 and descriptions are provided for both sexes. Keys are presented to distinguish between the four described species in the genus.
The new species Lonchodes philippinicus sp. n. from Panay is described and illustrated based on bothsexes and the eggs. As currently treated the genus Lonchodes Gray, 1835 is shown to be polyphyletic. A critical discussion of the genus is presented, which briefly summarizes the generic units or specific groups recognized within the genus. Species subsequently attributed to Lonchodes Gray are here transferred to the genera Lonchodiodes gen. n., Mnesilochus Stål, 1877 and Hermagoras Stål, 1875. A list of species which belong in Lonchodes (sensu stricto) is provided.
The new genus Lonchodiodes gen. n. (type-species: Lonchodiodes samarensis sp. n.) and five new species are described and illustrated. Four species are known from both sexes and the eggs: Lonchodiodes atrovirens sp. n. and Lonchodiodes grandis sp. n. from Panay, Lonchodiodes samarensis sp. n. from Samar and Lonchodiodes babuyanensis sp. n. from the Babuyan Islands. Lonchodiodes eurycanthoides sp. n. from Mindoro is described from the male and female alone. Three species are transferred from Lonchodes Gray, 1835 to Lonchodiodes gen. n.: Lonchodes putingmantsa Zompro, 2003 comb. n., Lonchodes tagalicus Stål, 1877 comb. n. and Lonchodes trollius Westwood, 1859 comb. n.. The female and egg of L. trollius (Westwood, 1859) are described and illustrated for the first time and a re-description is provided of the male. Keys are presented to distinguish between the eight known species in the genus.
A list of species is presented for Periphetes Stål, 1877. One new species, Periphetes quezonicus sp. n., is described from Luzon based on the female and male. A detailed description and illustrations of the egg of Periphetes forcipatus (Bates, 1865) from Sulawesi are provided. Dixippus furcatus Brunner v. Wattenwyl, 1907 and Periphetes duivenbodei elongatus Günther, 1938 from Sulawesi and Periphetes sangirensis Dohrn, 1910 from Sangihe Island shown to be junior synonyms of P. forcipatus (Bates) (syn. n.). Lectotypes are designated for Lonchodes analis Brunner v. Wattenwyl, 1907 and Lonchodes forcipatus Bates, 1865.
The new genus Matutumetes gen. n. is described for two new species from Mindanao, both of which are known from the male and female: M. amoenus sp. n. and M. mindanaensis sp. n.. This new genus is well characterized by the strikingly prominent praeopercular organ of females. The eggs of Matutumetes gen. n. remain unknown.
Mnesilochus Stål, 1877 is re-established (stat. rev.), re-described and distinguished from related genera. A list is presented of the 13 species currently included, 11 of which are here transferred from either Lonchodes Gray, 1835 (sensu lato) or Phenacephorus Brunner v. Wattenwyl, 1907 (new combinations). The female and egg of Mnesilochus headulus Stål, 1877 are described and illustrated for the first time and a re-description is provided of the male. Prisomera tuberculatum Brunner v. Wattenwyl, 1907 is synonymised with Mnesilochus mindanaense (Brunner v. Wattenwyl, 1907) syn. n.. Prisomera modestissimum Brunner v. Wattenwyl, 1907 was synonymised with Mnesilochus modestus (Brunner v. Wattenwyl, 1907) in error and is shown to be a synonym of Paraprisomera coronata (Brunner v. Wattenwyl, 1907) n. syn.. The type-locality “S.O. Borneo” is shown to be wrong, the specimens most certainly originating from Sri Lanka.
A review is presented of the genus Manduria Stål, 1877, along with a re-description and brief notes on its systematic position. A key is provided to distinguish the females. The female paralectotype of Lonchodes systropedon Westwood, 1859 in BMNH is shown to be a specimen of M. bilobatus (Brunner v. Wattenwyl, 1907).
Holotypes of most new taxa are deposited in the State Zoological Collection Munich, Germany (ZSMC), paratypes in various public and private collections.
Eggs of Phasmida are characterized by the presence of a micropylar plate system. The nature of this plate is discussed and the relevance of differences in plate structure to the taxonomy of the order is considered. A survey is made of the range of plate structure throughout the order, covering the external plate structure of 384 species and the internal plate structure of 179 species in forty of the forty-four subgroups of the order.
