Okumura, Ken-ichi, 2013, Seven New Species of Spiders of the Subfamily Coelotinae (Araneae: Agelenidae) from Kyushu, Japan, Species Diversity 18, pp. 87-97 : 93-95

Draconarius verrucifer sp. nov.

[Japanese name: Higo-yachigumo] ( Fig. 5E–H )

Material examined. Holotype. NSMT-Ar 9865, female, Minami-aso village, Aso county , Kumamoto Prefecture (coordinates unknown), 18 February 1990, Yoh Ihara leg.

Paratype. NSMT-Ar 9866, same as holotype, 1 female, 17 February 1990, Yoh Ihara leg .

Non-type specimens. Kikuchi-keikoku, Kikuchi city, Kumamoto Prefecture, 1 female, 16 February 1990, Yoh Ihara leg .; Izumimachi, Yatsushiro county , Kumamoto Prefecture, 2 females, 28 March 2001, Yoh Ihara leg .; northern area of Mt. Sobo, Oita Prefecture, 1 female, 27 August 2007, Shingo Hatsushiba leg .

Diagnosis. The new species belongs to the Draconarius venustus group, as is shown by the structure of the copulatory ducts close to each other, complexly convoluted several times, and externally looking like gill slits of sharks; spermathecae situated in posterolateral parts of endogynum.

Coloration: carapace yellowish brown, with indistinct radial flecks; dorsum of abdomen yellowish gray with indistinct chevrons; sternum yellowish brown; chelicerae brown; maxillae and labium yellowish brown; legs yellowish brown without ring flecks.

Distribution. Kumamoto and Oita Prefectures ( Fig. 6 ).

Etymology. The specific name is a Latin adjective (- fer, - fera, - ferum), derived from verruca, “a wart”, and the suffix - fer, “bearing, carrying”, referring to the small protrusion of the epigynum in the new species.

Remark. The new species is characterized by having a single protrusion located in the central region of the posteri- or margin of the epigynum. Although the male is unknown, this new species can be easily distinguished from the other coelotine spiders by its unique female characteristics as mentioned above.
