Genus Neotachardiella Kondo, Peronti & Pacheco da Silva , gen. nov.

Type species: Tachardiella ourinhensis Hempel, 1937: 8‒9 .

Generic diagnosis. Dorsum. Dorsal setae generally absent. Dorsal macroducts absent. Microducts and spermatoid ducts present. Brachial tube (brachium) short or long. Brachial plate sclerotized, with a shallow crater. Brachial pores numerous, quinquelocular, with loculi very hard to detect. Anterior spiracles present dorsally, large, similar in size to brachial plates or slightly smaller. Anal tubercle well developed. Anal fringe composed of short, spinose ligulate lobes (never as long as anal ring setae), those on mid-areas mostly with bifurcate apices, with those on the sides spiniform. Dorsal spine well developed but short relative to body size; pedicel short or long. Anal ring divided into 4 plates, with a total of 10 setae. Eyespots absent. Venter. Antennae small, with segmentation indistinct, 3- or 4-segmented, with 5–8 setae on apex of apical segment. Mouthparts well developed; labium 1 segmented. Legs present, very small and hard to detect, reduced to small sclerotic peg-like claws; anterior pair greatly reduced, usually represented by a small sclerotic point or claw; posterior leg remnants usually largest. Canellae present. Ventral setae present, very small. Posterior spiracles ventral, much smaller than anterior spiracles. Spiracular pores present, mostly quinquelocular. Marginal duct clusters sclerotized, forming subcircular to oval plates (composed of macroducts, spermatoid ducts, and sometimes incorporating setae that may be inside, touching or near the cluster), numbering 12 (6 on each side), with 4 clusters present submarginally on head between canellae (2 each side) and 4 clusters submarginally on each side between each canella and body apex. Spermatoid ducts present, similar in size and shape to those on dorsum. Ventral duct clusters numbering 8 (4 pairs), posterior pair sometimes subdivided or with a constriction. Microducts present. Perivulvar pores and perivulvar pore clusters absent.

Etymology. The name of the new genus, Neotachardiella (gender feminine), is formed by the combination of the Greek word “ neo ” meaning new and Tachardiella , indicating the close relationship of the two genera.
