Differential diagnosis

Morphology

Porricondyla pilosoides sp. nov. differs from P. pilosa , a broadly similar species, as follows. The gonostylus of P. pilosoides is broadly rounded apically, with the entire curve occupied by a tooth consisting of countless, irregularly arranged spines (↓ 1, Fig. 26A ), whereas in P. pilosa the gonostylar apex is pointed and equipped with a comparatively small brush of spines ( Jaschhof & Jaschhof 2013: fig. 102a). Also, the gonocoxal processes of P. pilosoides are slightly bent outwards (↓ 2, Fig. 26A ), while those of P. pilosa are slightly bent inwards ( Fig. 26C ). Apart from these distinctions in terminalia structures, the flagellomeral necks of P. pilosoides are shorter compared to those of P. pilosa ; in the fourth flagellomere, the neck is 1.5‒1.6 × the length of the node in P. pilosoides ( Fig. 26B ) versus twice the nodal length in P. pilosa . Larvae and females of the new species are unknown.

DNA barcode

CO1 sequences (652bp) of the type specimens are available in BIN BOLD:AEO7195. Search on BOLD’s BIN Database retrieved no further result for this BIN (accessed 27 Aug. 2023).

Etymology

The specific epithet means ‘ pilosa -like’, an allusion to the close resemblance of the new species to P. pilosa .
