Description

Genus

YunohamellaYoshida, 2007

Type species.

Theridion yunohamense Bösenberg & Strand, 1906 (= Yunohamella yunohamensis) from Japan.

Diagnosis.

Species of Yunohamella are similar to those of Takayus (compare Figs 2 A – D, 4 A – D, 5 C – E, 6 C, D, 7 D – F, 8 A, B, 9 D – F; Gao and Li 2014: figs 107–109; Marusik and Logunov 2017: figs 37–39; Lee and Kim 2021: figs 3 E – G, 4 A, B with Zhu 1998: figs 80 B – E, 83 B – E, 93 B – E, 94 B – E, 108 B – E, 114 B – F, 115 B – E, 116 B – E, 117 B – E, 118 B – E, 119 B – E, 120 B – D, 125 B, C) in having a large tegulum and a small median apophysis, a conductor conjugating with tegulum. However, Yunohamella can be distinguished from Takayus by the following: embolus thin; tegular apophysis distinct; and epigyne without a pointed scapus or with a blunt scapus (vs embolus broad, tegular apophysis invisible before expanded, epigyne with a pointed scapus in Takayus).

Species of Yunohamella can be distinguished from Theridion (compare Figs 2 A – D, 4 A – D, 5 C – E, 6 C, D, 7 D – F, 8 A, B, 9 D – F; Gao and Li 2014: figs 107–109; Marusik and Logunov 2017: figs 37–39; Lee and Kim 2021: figs 3 E – G, 4 A, B with Zhu 1998: figs 73 B – E, 76 B – E, 85 B – E, 88 B – E, 89 B – D, 90 B – E, 91 B, C, 97 B – E, 98 B – E, 106 B – E, 109 B – E, 110 B – D 123 B – E, 124 B – E) by the following: embolus short and straight; tegulum large; conductor conjugating with tegulum; epigyne without depression (vs embolus long and circular; tegulum not large; conductor separated; epigyne with a distinct depression in Takayus) (Yoshida 2007).

Species of Yunohamella can be distinguished from Cryptachaea (compare Figs 2 D, 4 D, 8 A, B; Levi 1957: fig. 323 with Levi 1955: fig. 82) in having a median apophysis separated from the embolus and the present tegular apophysis (vs median apophysis attached to the embolus and tegular apophysis absent in Cryptachaea).

Distribution.

Asia, Europe, North America.
