First record of the subfamily Coelotinae in Laos, with review of Coelotinae embolus morphology and description of seven new species from Laos and Vietnam (Araneae, Amaurobiidae)

摘要

First records of Coelotinae are reported from Laos. Five new species of the genus Draconarius are described from the northern Luang Nam Tha Province: Draconarius bounnami sp. nov. (male), D. latidens sp. nov. (female), D. postremus sp. nov. (male, female), D. songi sp. nov. (male) and D. tabularis sp. nov. (female). In addition, two new Coelotinae species are described from Vietnam: D. hanoiensis sp. nov. (female) and D. huongsonensis sp. nov. (female). Of the 429 currently valid Coelotinae species, 154 of them have only females described (36%). The embolus characteristics of those with males described (275 species, 64%) are reviewed. Two characters have been found that might be informative for the estimation of phylogeny, and their congruence with the current Coelotinae classification system is discussed. One character is the point from which the embolus arises and another is the embolus shape.
