Summary Pnyxiopalpus gen.n. (type‐species P . raptor sp.n.), Oriental in distribution, includes the following species: P . acanthipes sp.n. (Malay Peninsula), P . aculeatus sp.n. (Borneo), P . adebratti sp.n. (Borneo), P . aphrodite sp.n. (Sumatra), P . dentaneus sp.n. (Sulawesi), P . fossor sp.n. (Borneo), P . fuscinellus sp.n. (Borneo), P . hamatus sp.n. (Borneo), P . latifalx sp.n. (Borneo), P . macrocellus sp.n. (Malay Peninsula), P . microdon sp.n. (Sumatra), P . nepenthophilus sp.n. (Malay Peninsula), P . noona sp.n. (Palawan), P . raptor sp.n. (Borneo), P . reticulatus sp.n. (Malay Peninsula) and P . simplex sp.n. (Borneo). Males and females are keyed and described. Pnyxiopalpus has a number of characters previously unknown in Sciaridae. In contrast to other Sciaridae, interspecific morphological variation is greater for the females compared to the males. Based on a parsimony analysis of sixty‐four morphological characters, Pnyxiopalpus is monophyletic, and its sister group appears to be Spathobdella Frey + {[ Peyerimhoffia Kieffer + ( Faratsiho Paulian + Pnyxia Johannsen)] + [ Hyperlasion Schmitz + ( Hermapterosciara Mohrig & Mamaev + Parapnyxia Mohrig & Mamaev)]}. According to the most parsimonious solution, the monophyly of Hyperlasion , Lycoriella Frey and Plastosciara Berg in their current sense is questioned. Aptery and one‐segmented maxillary palp, usually regarded as important in sciarid classification, show a lot of homoplasy.
