Zoobank registration: urn: lsid: zoobank. org:act: 5DD3AC90-782C-4455-91F0-8CF232C0951F

Etymology: The generic name is based on the genus Symphylurinus Silvestri, 1909 , with the Greek suffix - opsis (meaning, ‘sight, appearance’; thus ‘looking like’). The gender of the name is masculine.

Type species: Symphylurinopsis punctatus sp. nov. by monotypy.

Diagnosis: Male. The new genus is readily distinguished from all other genera in the family Projapygidae by the following combination of characters: cuticle dorsally and ventrally with distinct setigerous punctures; antenna short, 0.3× length of body, with 23 antennomeres, dolioform; antennomere II with secondary sexual characters, lacking secondary sexual characters on antennomere III and pyriform sensillum on antennomere VII; labial and maxillary palpi uniarticulate and elongate, the maxillary palpus longer than the labial palpus; legs short, slightly increasing in length from first to third pair; tibiae without comb of spatuliform setae and with calcars; claws subequal; cercus elongate, 0.3× length of body, with 15 segments plus the infundibuliform complex, basal segments I–V fused, without secondary sexual characters.
