Diagnosis

This species is characterized as follows: dorsal setae reaching setae immediately behind, seta d on femur I positioned in front of l’, femur II with three setae (d, v’ and v”), femur III with two setae (d and v’), setae d on genua I–IV slightly less than half as long as tibiae I–IV respectively, dorsal seta d1 less than half as long as width of body; dorsal setae c1 as long as setae d1, setae v” on femora I–II positioned distinctly in front of v’.

Etymology

The specific name makes reference to the municipality Tepoztlán, where the type locality is situated. The name of the municipality derives from two words in the náhuatl language, “Tepoztecatl” (a nahua divinity) and “tlan” (beside), so its meaning is “in the company of Tepoztécatl”.

Remarks

Neophyllobius tepoztlanensis sp. nov. resembles N. marginatus De Leon, 1958 collected from an undetermined composite plant and Quercus sp. in Nayarit, Mexico. In both species, the dorsal setae on genua I–IV are short, less than half as long as tibiae I–IV; the setae on femur I are short (about a quarter of the length of the podomere). These species can be differentiated by the following characters: in N. tepoztlanensis sp. nov., dorsal setae c1 as long as setae d1, and setae v” on femora I–II positioned distinctly in front of v’. In N. marginatus , dorsal setae c1 about half as long as seta d1, and setae v’ and v” on femora I–II are positioned horizontally on nearly the same level.

Ecology

Neophyllobius tepoztlanensis sp. nov. is deemed to be an inhabitant of the tree canopy and was found on Tillandsia schiedeana and T. hubertiana at 2.7 m (± 0.4) on Sapium macrocarpum .

Distribution

This species is only known from San Andrés de la Cal, Morelos, Mexico. The type locality of N. tepoztlanensis sp. nov. is about 600 km from Ixtlán del Río, Nayarit, Mexico and 660 km from Tepic, Nayarit, the two known localities of N. marginatus .
