Head: eyes small, convex, without a distinct internal canthus; male usually with elongated or laterally enlarged mandibles; clypeal area not sharply delimited, or if so, transversely triangular with obtuse upper angle and widely splayed raised margins for holding antennae in repose; antennae not serrate, longer than head width, antennomeres 7–11 elongate and expanded, each with dense basiconic sensilla in apical circular pit.

We have revised the description here, based on a larger sample of species. Schöller also included + +Nyetra +Baly 1877 + +as a junior synonym of + +Scaphodius + +, with which we concur. + +Nyetra + +was described for a large species, with dorsal pubescence and extreme sexual dimorphism, in contrast to the +type +species of + +Scaphodius + +, small, dorsally glabrous and with slight sexual dimorphism, but there are intermediates in size and structure between these extremes, as noted by Schöller. + + +Schöller listed 12 species in + +Scaphodius + +but this figure excludes species wrongly placed in the Australo-Papuan genus + +Ditropidus +Erichson, 1842 +( +Schöller 2009 +) + +. Schöller treated the five species of + +Ditropidus + +described by +Fauvel (1907) +as either belonging to that genus ( + +D. opacicollis + +only) or +nomina nuda +, because they lacked detailed descriptions. However, these latter names were partially described by +Fauvel (1907) +as part of a key written to differentiate the species, which therefore makes them available (ICZN 1999, Art 12.1), although the species are unidentifiable from the key. Fauvel seems to have placed his species in + +Ditropidus + +based on size and colour, neither of which is valid, and faulty biogeography, influenced by +Chapuis (1875a +, b). Chapuis had listed + +D. punctulum +Chapuis, 1875a + +, from Sydney, Adelaide and +Fiji +, and + +D. tibialis +Chapuis, 1875a + +, from Sydney, Clarence River, Brisbane and +Fiji +. Chapuis also described + +Cryptocephalus fraterculus +Chapuis, 1875b + +, from +Fiji +. All three of these species are Australian, absent from +Fiji +( +Bryant & Gressitt 1957 +; +types +examined by CAMR) and the specimens from +Fiji +examined by Chapuis must have been wrongly labelled. Note that + +D. punctulatus + +of +Bryant & Gressitt (1957) +is a misidentification. Fauvel was therefore misled in believing that + +Ditropidus + +occurred in “Polynesia” ( +Fauvel 1907: 152 +). + + +We have examined the male +holotype +of + +D. opacicollis + +. This is a small but otherwise typical species of + +Scaphodius + +, with ovate eyes, laterally expanded mandibles, strongly divergent facial antennal grooves and strigose pronotum (= + +S. opacicollis +(Fauvel) + +, + +comb. nov +. + +). We have not seen any + +Ditropidus + +species in abundant material of +Cryptocephalinae +from +New Caledonia +. Fauvel’s generic diagnoses are clearly incorrect. We therefore feel justified in placing all of the other Fauvel names in + +Scaphodius + +: + +S. aeneus +( +Fauvel, 1907 +) + +, + +comb. nov +. + +, + +S. nitidus +( +Fauvel, 1907 +) + + +comb. nov +. + +, + +S. striolatus +( +Fauvel, 1907 +) + + +comb. nov +. + +, + +S. sulcatus +( +Fauvel, 1907 +) + + +comb. nov +. + + + +The only species of + +Scaphodius + +supposedly from outside +New Caledonia +, + +S. compactus +Sharp, 1881 + +, was described from +New Zealand +. This is an Australian species of + +Ditropidus + +, either mislabelled from +New Zealand +or adventitive but no longer extant in that country ( +Leschen & Reid 2004 +; +Schöller 2009 +). + + +The net result of these changes is that + +Scaphodius + +is endemic to +New Caledonia +and + +Ditropidus + +is confined to +Australia +and New +Guinea +. + + +Two new species in the material available to us show particularly bizarre sexual dimorphism and are described below.

The statement that Medvedev “erroneously dated it as 1861” ( +Konstantinov & Prathapan 2008: 391 +) is therefore incorrect. Furthermore, the genus was originally credited with two species, both new, one described by Westwood and one by Baly. A +type +species was not clearly designated and the genus was not monotypic, therefore the statement by +Wilcox (1973: 656) +, that + +C. latifrons +Westwood + +is the +type +species by monotypy, was erroneous. Ironically, Wilcox's statement constitutes a +type +species designation in itself (International Code of Zoological Nomenclature 1999, Art. 69.1.1), which is + +C. latifrons +Westwood + +, by subsequent designation of Wilcox. This was overlooked by +Konstantinov & Prathapan (2008) +, who uneccessarily made the same designation. + + +Konstantinov & Prathapan (2008) +synonymised + +Priostomus +Jacoby, 1884 + +, with + +Chaloenus + +. The genus + +Chaloenus + +has recently been revised ( +Takizawa 2012 +) with these two concepts, + +Chaloenus + +and + +Priostomus + +, retained as subgenera, separated primarily by antennal proportions. + + + +Chaloenus + +is one of many genera of the leaf beetle subfamily +Galerucinae +with greatest diversity on the Sunda Shelf of south-east Asia. There are 42 described species ( +Takizawa 2012 +), 36 of which are recorded from Borneo. The new species described below is also Bornean and belongs to the nominate subgenus. + + + + \ No newline at end of file diff --git a/data/03/A0/87/03A087CCD55FFFBA1F89F966FBD1FADA.xml b/data/03/A0/87/03A087CCD55FFFBA1F89F966FBD1FADA.xml new file mode 100644 index 00000000000..8357577429c --- /dev/null +++ b/data/03/A0/87/03A087CCD55FFFBA1F89F966FBD1FADA.xml @@ -0,0 +1,275 @@ + + + +Chrysomelid males with enlarged mandibles: three new species and a review of occurrence in the family (Coleoptera: Chrysomelidae) + + + +Author + +Reid, C.

Etymology: +named for the fierce (Latin: +ferox +) appearance of the male. + + + +Sensory organs on the head are sexually dimorphic in size, as compared against body length, measured from anterior margin of pronotum to apex of elytra: greatest diameter of eye 16% (male) or 14–15% (female) body length; antennal length 76% (male) or 45–46% (female). + + + +This is one of many species of + +Scaphodius + +with greatly modified mandibles and extended clypeal or genal lobes ( +Schöller 2009 +; +pers. obs +. CAMR). Six of the 41 species with males available to us have a spine on the inner edge of the male mandible. However, + +S. ferox + +is the only species we are aware of with a smooth glabrous dorsum and an elongate dorsally directed tooth at the base of each mandible. There are several shining black undescribed species, but with relatively unmodified male mandibles and at least slightly punctate or strigose pronotum.
