Genus Coddingtonia Miller et al., 2009

Coddingtonia Miller, Griswold & Yin, 2009: 30.

Luangnam Wunderlich, 2011: 431.

Coddingtonia : Labarque and Griswold 2014: 419 (synonymized with Luangnam ).

Type species.

Coddingtonia euryopoides Miller et al., 2009 by original designation.

Diagnosis.

The male of Coddingtonia may be distinguished from other theridiosomatids by the mesal bristle of the embolic apophysis ( Fig. 3A, B, D ; Wunderlich 2011: figs 3, 5). The female of Coddingtonia can be distinguished from other theridiosomatids by the following combination of characters: spermathecae separated by about one diameter ( Figs 1E, F , 2F, G , 4E, F , 5D, E ) vs. juxtaposed and partially fused together (Coddington, 1986), long and coiled copulatory ducts surrounding the spermathecae, but lacking that in other theridiosomatids ( Figs 1E, F , 2F, G , 4E, F , 5D, E ).

Composition.

Coddingtonia anaktakun Labarque & Griswold, 2014 (Malaysia), C. erhuan sp. nov. (China), C. discobulbus (Wunderlich, 2011) (Laos), C. euryopoides Miller et al. 2009 (China), C. huifengi sp. nov. (Indonesia), and C. lizu sp. nov. (China).

Distribution.

Southern China (Yunnan, Hainan), Laos, Thailand, Malaysia, and Indonesia ( Fig. 6 ).
