A new species of the genus Diplocentrus Peters, 1861, is herein described from Unión Cantinil (1704 m a.s.l.; 15\° 35\’ 46.3\’\’ N \– 91\° 45\’ 43.6\’\’ W), Huehuetenango department, Guatemala, based on a single adult male. It differs from Diplocentrus chol Francke, 2007 in the following characters: (1) tarsomere II of legs II-IV with 4/4:5/5:5/5:5/5 ventral spiniform setae (4-5/5: 5/5-6: 6/6 in D. chol); (2) pectines with 9 teeth (10-13 in D. chol); (3) pedipalp femur more granulose; (4) telson less globose (length/height ratio = 2,9 vs 2,5 in D. chol).

Three species of genus Diplocentrus are found in north-northwestern Honduras. These species represent the southern east limits of Diplocentrus\’ distribution. In recent years, a broad survey of arachnids in Honduras has yielded a collection of several specimens of an undescribed species from two islands in northern Honduras. This new species represents the second species of the genus inhabiting an island. The present contribution describes this new species, and compares it against its most similar relatives. A dichotomous key for the identification of the species of Diplocentrus in Honduras is also included

The scorpion genus Diplocentrus Peters, 1861, endemic to North and Central America, is the most diverse in family Diplocentridae Karsch, 1880. There is considerable morphological variation among the species of Diplocentrus. It is necessary to test the monophyly and phylogenetic position of Diplocentrus in order to revise its diagnosis and taxonomic limits. The present contribution provides a phylogenetic analysis of 29 species of Diplocentrus, five exemplar species representing the three putatively most closely related diplocentrid genera, and an exemplar of a more distantly related diplocentrid genus. The analysis was based on 95 morphological characters and 4202 aligned nucleotides from DNA sequences of five markers in the nuclear and mitochondrial genomes. Separate and simultaneous parsimony analyses of the morphological and DNA sequence data were conducted with equal weighting and six implied weighting regimes. The nuclear and mitochondrial DNA datasets were also analyzed separately and simultaneously with Bayesian inference. The resulting topologies recovered the monophyly of Diplocentrus, with the exception of two neobothriotaxic species from central Mexico, for which a new genus Kolotl Santibáñez-López et al., 2014, is justified. The keyserlingii group, as previously defined, was not monophyletic due to the placement of two species in the mexicanus group; the rest of its component species were monophyletic, however. A third clade was recovered that has not been previously recognized: the zacatecanus group, comprising four species from northern Mexico and the southwestern U.S.A. New insights are provided concerning relationships among Diplocentrus and the diplocentrid genera Bioculus Stahnke, 1968 and Didymocentrus Kraepelin, 1905, the phylogenetic positions of which were previously ambiguous.

The poorly known Central American scorpiofauna (excluding Mexican lands) contains 38 species belonging to 11 genera, and 5 families (Buthidae, Chactidae, Diplocentridae, Ischnuridae, and Vaejovidae). Most of them (24 species) are Central American endemics. Centruroides, with 10 species, is the most diverse and widespread genus in this territory, whereas all the seven Diplocentrus species are restricted to the area. Didymocentrus, with two species, is the only scorpion genus that apparently has a Central American center of dispersion. Panama contains the highest diversity (17 species, 8 genera, and 4 families), but shows a low endemism (17,6 \%), only higher than that of El Salvador (0 \%).

Resumen: Se describen dos especies nuevas del género Diplocentrus Peters, 1861, sobre la base de tres hembras recolectadas en los departamentos Petén e Izabal, Guatemala. Por su aspecto general, la especie de Izabal se asemeja a D. lourencoi Stock- well, 1988, del mismo sistema montañoso (Cordillera del Merendón), pero en Honduras. La especie de Petén se asemeja a D. ma- ya Francke, 1977, que se distribuye en el sur de Belice (Toledo) y el nordeste de Guatemala (Petén e Izabal). Abstract: Two new species of the genus Diplocentrus Peters, 1861 are described on the basis of three female specimens from the departments of Petén and Izabal, Guatemala. The species from Izabal resembles D. lourencoi Stockwell, 1988, from the same range (Cordillera del Merendón) but in Honduran territory. The species from Petén resembles D. maya Francke, 1977, recorded from Belize (Toledo District) and north-eastern Guatemala (departments of Petén and Izabal).
