Genus Goblinia Lin & Li gen. nov.

Type species.

Goblinia tiane sp. nov. from Guangxi, China.

Diagnosis.

Goblinia gen. nov. can be distinguished from Iberina Simon, 1881 by the spineless male palpal femur (Fig. 6A, B ) [vs femur with 3-5 spines (see Růžička 2022: fig. 2O)], embolus shorter than perimeter of bulb (Figs 3A , 4A ) [vs almost 2 × longer (see Růžička 2022: fig. 4A-E)] and epigyne with one pair of spermathecae (Fig. 5B ) [vs two pairs of spermathecae, except for I. difficilis (Harm, 1966) and I. microphthalma (Snazell & Duffey, 1980) (see Růžička 2022: fig. 5A-E)].

Description.

Male. Total length 1.87-2.40 (n = 5). Carapace pale yellow, covered with few black setae. PER longer than AER, AER and PER procurved. AME separated by less than their diameter, closer to ALE; PME separated by almost their diameter, approximately as far from ALE; Distance between AME and PME longer than that between ALE and PLE; ALE and PLE almost touching. Clypeus pale yellow, covered with few setae. Chelicerae pale yellow, with three promarginal and three retromarginal teeth, with granular stridulatory files retrolaterally (Fig. 2A ). Endites, labium pale yellow, covered with few black setae. Sternum coloured as endites, covered with brown setae. Legs pale yellow. Opisthosoma oval, white. Spinnerets white, M-shaped in posterior view. Tracheal spiracle long and transverse, distance of spiracle to epigastric furrow as long as to spinnerets.

Palpal femur almost 4 × longer than patella, spineless. Patella shorter than tibia. Retrolateral tibial apophysis almost as long as tibia, curved to almost 100° angle. Cymbium egg-shaped, cymbial furrow almost as long as bulb. Bulb discoid round, without conductor. Sperm duct with curved course. Embolus whip-shaped, starting at ca 4:30 o’clock position.

Female. Total length 1.96-2.55 (n = 5). Somatic characters as in male but chelicerae with two promarginal and three retromarginal teeth, stridulatory files absent.

Epigynal plate wider than long. Copulatory openings located anteriorly, round, touching each other. Copulatory ducts long and intertwined, beginning laminar. Glandular appendages round, touching each other. Spermathecae oval, located posteriorly, separated by less than radius.

Etymology.

The new generic name is a combination of goblin (a legendary creature that lives underground) and Hahnia. The gender is feminine.
