A New Genus of Odontopygid Millipeds from Tanzania (Diplopoda: Spirostreptida: Odontopygidae)
Article
  • Sep 2012
The new generic taxon Calyptomastix is proposed to accommodate the type species Odontopyge kakandae Kraus, 1958, and, tentatively, Odontopyge dorsalis Carl, 1909, Haplothysanus leviceps Attems, 1909, and Spirostreptus pardalis Gerstäcker, 1873, all from Tanzania. This genus is defined by the broad basal separation of the male genitalia, the elongat...
On the identity of the generic name Iulidesmus Silvestri, 1895 (Polydesmida: Paradoxosomatidae)
Article
  • Feb 2012
One of the most enigmatic of the early generic names impacting negatively on the taxonomy and nomenclature of Neotropical diplopods is Iulidesmus, proposed by Filippo Silvestri in 1895. The type species Iulidesmus typicus was based upon a female holotype, so that the structure of the male genitalia was (and remains) unknown for the species and genu...

New genera for two poorly-known millipeds from Bahia (Polydesmida: Chelodesmidae)
Article
Full-text available
  • Dec 2011
Two chelodesmid millipeds described by Brölemann (1903) from the interior of Bahia have not been reported for over 100 years despite their large size and bright coloration. Originally described as Leptodesmus gounellei and Leptodesmus carminatus, neither species is referable to Leptodesmus as currently defined nor any other established genus. Both...

The curious genitalic structures of Tancitares michoacanus (Polydesmida, Rhachodesmidae)
Article
Full-text available
  • Oct 2011
The unusual male and female structures in Tancitares michoacanus Chamberlin, l942, inadequately docu-mented in the original description, are redescribed and illustrated from type material. The species is re-ported from a locality in Colima, Mexico, the second known for this species. Pararhachistes Pocock, 1909, is suggested as a possible closely re...
A new Colombian species in the milliped genus Psammodesmus, symbiotic host for bryophytes (Polydesmida: Platyrhacidae)
Article
Full-text available
  • Sep 2011
The name Psammodesmus bryophorus is proposed for an ornate platyrhacid milliped discovered in a transitional Andean- Pacific montane rainforest in Narińo Department, Colombia. This species is remarkable for being the first milliped known to be host of ectocommensal mosses (10 species belonging to 5 families including especially Pilotrichaceae and L...
A new genus for a colorful spirostreptid milliped from East Africa (Diplopoda: Spirostreptida: Spirostreptidae)
Article
  • Jun 2011
The new generic taxon Sagmatostreptus is proposed for the type species Spirostreptus strongylopygus Attems, 1950, endemic to a limited area in northeastern Tanzania and adjacent Kenya.
Cyclocephala Nigricolus Burmeister (Coleoptera: Scarabaeidae: Dynastinae: Cyclocephalini). What is It? And Where is It?
Article
  • Jun 2011
"Cyclocephala nigricollis" Burmeister is a relatively common species in some parts of the southern United States, with disjunct populations in Virginia and the Carolinas in the eastern United States. After examination of specimens and the literature, we conclude that nigricollis is a nomen dubium and that its neotype was invalidly proposed. Accordi...
First North American Record of the Old World Cylapine Fulvius subnitens Poppius (Hemiptera: Heteroptera: Miridae) from Virginia, with Descriptions and a Key to the U.S. Species of Fulvius
Article
  • Jun 2011
The first North American record for Fulvius subnitens Poppius is reported based on one specimen collected in southcentral Virginia. Fulvius anthocoroides (Reuter), Fulvius imbecilis (Say), Fulvius slateri Wheeler, and Fulvius subnitens are diagnosed and described, and color images of adults, updated distributions, a review of feeding habits, and an...
Rondostreptus, a new spirostreptid genus from southeastern Tanzania (Diplopoda: Spirostreptidae)
Article
  • Feb 2011
The name Rondostreptus kiellandi is proposed for an undescribed genus and species of Spirostreptidae apparently endemic to the Rondo Plateau in southeastern Tanzania. It appears to have no close relatives among the known spirostreptid fauna of East Africa.
A review of the milliped genus Haplogonopus with commentary on the so-called "Charactopygus-Bildung" modification of spirostreptid paraprocts (Diplopoda: Spirostreptidae)
Article
  • Jan 2011
The status of the monotypic taxon Haplogonopus (Verhoeff, 1941), proposed for a disjunct Tanzanian spirostreptoid, is reviewed in light of two additional species, which despite different peripheral appearances, are referable to this genus on the basis of genitalic features. Haplogonopus inflatannulus Verhoeff is redescribed from topotypic material,...

... Indian millipedes are inadequately studied with only about 270 described species in 90 genera, 25 families and 11 orders from the whole country (Golovatch & Wesener 2016). In comparison, 473 millipede species have been described from Italy (Foddai et al. 1995) and 296 species from Tanzania (Enghoff et al. 2016) -both countries with a much smaller land mass than India. More than 90% of Indian millipedes were described by Western scientists during the colonial period, based on specimens housed in European museums or specimens sent from India (Pocock 1892(Pocock , 1898Silvestri 1916Silvestri , 1917Silvestri , 1923. ...

According to Hoffman (2012), the morphology of the female genitalia has some important characters and may be decisive for developing a more solid classification.
