Genus Tonkinomeris , new genus

Type species. Tonkinomeris napoensis , new species by original designation.

Diagnosis. The new genus is similar to Peplomeris Silvestri, 1917 from Vietnam by having elongated telopods with femoral and tibial processes. The genus is differentiated from other genera by the leg-pair 18 being very stout, with

a short, stout, sparsely setose tubercle on podomere 3. In contrast, Peplomeris possesses a normally reduced leg-pair 18 and lacks the tubercle. Telopods elongate, without femoral trichosteles, but with a short, stout tuberculiform trichostele on the telepodal prefemur. Telopod femur straight. Distal outgrowth of telepodal tibia a large lamelliform processabsent in Peplomeris . Telepodal syncoxial lobe rounded trapeziform—not emarginated medially as in Peplomeris .

The new genus is tentatively assigned to the subfamily Haploglomerinae Mauriès, 1971 based on the simple, elongate telopods and lack of a femoral trichostele. See discussion of the current glomerid classification below.
