Lepidonella Yosii, 1960

Paronellinae with 8+8 eye; antennae shorter than the body; first antennal segment shorter than head; Ant. 4 not subdivided or annulated; apically rounded or truncate scales present on head, body and ventral face of furcula; Abd. 2-4 with 2, 3, 2 bothriotricha; dorsal chaetotaxy complete or almost complete, with few dorsal macrosetae; metafemoral organ absent; manubrial spines absent; dens with 1-2 rows of spines; distal lobe of dens absent; mucro variable, with 3-5 teeth.

REMARKS

As defined above, Lepidonella differs from Bromacanthus only in the absence of the femoral organ. Mucro morphology in Lepidonella is unusually variable, even for a paronellid, and several Lepidonella species share the compact mucro present in Bromacanthus . The combination of mucro shape and geographic distribution suggest Lepidonella may not be monophyletic. The analysis presented below identifies several putative chaetotaxy apomorphies (e.g., presence of head seta Pm2, metathoracic seta a6 inserted posterior to seta m5, etc.) supporting the monophyly of Lepidonella . However, most named species are poorly described and head and metathorax chaetotaxy is known only for the species described here.
