Marusik, Yuri M. & Omelko, Mikhail M., 2018, New data on Synaphosus (Araneae: Gnaphosidae) from Southeast Asia, Zootaxa 4374 (2), pp. 235-248 : 246

Synaphosus lehtineni sp. n.

Figs 28‒31 , 35‒41 , 50, 52‒53 , 54

Types: Holotype ♂ (ZMUT) and paratypes 1♂ 1♀ (ZMUT), INDONESIA, Sulawesi Tengah, Donggala d., Salena, bamboo-cocoanut forest, 25.10.1979 (P.T. Lehtinen). The specimens are in poor physical condition, only the holotype male’s prosoma and abdomen are still connected, in other specimens the abdomen are separated from the rest of the sample, the sample contains many specimens including juveniles, and it is impossible to recognize which carapace belongs to the paratype female.

Diagnosis. Males of Synaphosus lehtineni sp. n. are easily differentiated from congeners by the long and bent tibial apophyses not known in other species. Female of the new species is easily differentiated from congeners by having 2 pairs of receptacles: large egg-shaped anterior receptacles and round heavily sclerotized primary receptacles (with fertilization ducts). Other species of Synaphosus have only one pair of or either globular or tubeshaped receptacles.

Description. Holotype male: total length 3.95; carapace: 1.95 long and 1.38 wide. All legs lost. Palp as in Figs 28‒31 , 35‒38 ; femur and patella not modified; tibia with a long and bent retrolateral apophysis (Ta) 1.5 times longer than tibia, apophysis slightly widened at the tip; cymbium elongate, 2 times longer than wide; conductor (Cd) large, as long as cymbium, not covering entire tegulum (Te), with 2 retrolateral arms anterior (Aa) and posterior (Pa), both arms pointed; tegulum and subtegulum (St) well distinct; embolus relatively short, originating from 6 o'clock position, makes about 250° loop, broad at the base, basal outgrowth absent.

Female. Carapace missing. Epigyne as in Figs 39‒41 , 50, 52‒53 ; epigynal plate 1.5 longer than wide, without fovea, with small anterior pocket (Ap), copulatory opening located in centre of plate, divided by small septum (Se), ducts transverse, 2 pairs of receptacles, anterior receptacle (Ar) large egg-shaped, primary receptacle (Re) round heavily sclerotized.

Distribution. The species is only known from the type locality.
