Diplopoda — taxonomic overview

Tamaño Corporal y Segmentación del MilpiésEurhinocricus fissus1

“…Será recomendable revisar otros machos de BCS para ver si el holotipo era un macho excepcionalmente largo. Pero, en general, el intervalo de largo del cuerpo para E. fissus, comparado con el registrado para los representantes de la familia Rhinocricidae que oscila entre 18-200 mm (Enghoff et al 2015), corresponde a una especie que puede considerarse de talla pequeña a mediana.…”

Cryptic diversity in Andrognathus corticarius Cope, 1869 and description of a new Andrognathus species from New Mexico (Diplopoda, Platydesmida, Andrognathidae)

“…The order Platydesmida is differentiated from other Colobognatha by having chewing mouthparts, the trunk ring pleurites fused with the tergites, and a gnathochilarium composed of a plesiomorphic five sclerites (Enghoff et al 2015). Members of the order possess chemical defenses containing heterocyclic nitrogen-containing alkaloids and some members display paternal care (Gardner 1975; Shear 2015).…”

“…Andrognathuscorticarius has not been found in these formations. The families Andrognathidae and Platydesmidae are differentiated solely by the morphological trait of narrow sternites that make the coxae appear to be nearly contiguous in andrognathids (Cook and Loomis 1928; Enghoff et al 2015). However, proximity of coxae may be a homoplasy, and based on a recent phylogenomic analysis of the Diplopoda, the genera Platydesmus and Brachycybe are more closely related to one another than either is to Andrognathus thereby indicating non-monophyly of the family Andrognathidae (Rodriguez et al 2018).…”

The millipede genus Stemmiulus Gervais, 1844 in Cameroon, with descriptions of three new species (Diplopoda, Stemmiulida, Stemmiulidae)

“…According to the latest classification (Enghoff et al 2015), apart from two monobasic genera, one each in the Caribbean and Vietnam, the family is largely represented by the likewise pantropical genus Stemmiulus Gervais, 1844. Its 150+ species in comparable shares range from Central (one species introduced to Florida, USA) to northern South America (south to the Brazilian states of Amazônas and Bahia, as well as northern Peru), on the one hand, and Central Africa, on the other.…”
