Draconarius songi View in CoL sp. nov.
( Figures 58–65 View Figures 58–60 View Figures 61–65 , 75, 76 View Figures 75, 76. 75 )
Type material
Holotype male from Muang Sing , Nam Ha Protected Area, Luang Nam Tha Province, Laos, 745 m, 21 ° 08.0759N 101 ° 11.9919E, secondary forest, leaf litter, bank at stream, under stones, day and night, P. Jäger & V. Vedel leg., 4 November 2004, deposited in SMF. GoogleMaps
Etymology
The specific name is in honour and memory of Daxiang Song (deceased) for his contribution to Chinese arachnological research and for his support of the first author’s research on spider systematics; noun in genitive case.
Diagnosis
Males of this new species may be recognized by the tiny patellar apophysis, the distally situated lateral tibial apophysis, and the embolus base arising retrolaterally ( Figures 58–60 View Figures 58–60 ). Both the promargin and retromargin of the chelicerae have six teeth. ( Figure 62 View Figures 61–65 ).
Description
Male holotype. Medium-sized spider, total length 6.55 mm ( Figures 63–65 View Figures 61–65 ). Dorsal shield of prosoma 3.30 long, 2.30 wide; opisthosoma 3.25 long, 2.00 wide. AME smallest, approximately half the size of other eyes (AME 0.06, ALE 0.13, PLE 0.13, PME 0.11); AME separated by its diameter; AME, ALE, PLE close together, separated by about AME radius; PME separated from each other and from AME by approximately AME diameter, from PLE by slightly less than PME diameter (AME– AME 0.06, AME–PLE 0.03, ALE–PLE 0.03, PME–PME 0.06, PME–PLE 0.09, AME–PME 0.07) ( Figure 61 View Figures 61–65 ). Chelicera with six promarginal and six retromarginal teeth ( Figure 62 View Figures 61–65 ). Palp with a tiny patellar apophysis; retrolateral tibal apophysis occupying more than half of tibial length; lateral tibial apophysis small, situated distally; cymbial furrow long, extending more than half of cymbial length; conductor short, with broad lamella; median apophysis long, spoon-shaped, with free prolateral edge; embolus long, retrolateral in origin, arising in a 4 o’clock-position, running twothirds of an oval, extending and coiling beyond distal bulb ( Figures 58–60 View Figures 58–60 ).
Female. Unknown.
Relationships
Draconarius songi sp. nov. exhibits a typical Draconarius palp in having a patellar apophysis, a lateral tibial apophysis, a long cymbial furrow, a conductor dorsal apophysis, a spoon-shaped median apophysis, and a long, filiform embolus. The presence of six cheliceral teeth on both promargin and retromargin makes a definite generic placement difficult.
Distribution
Laos (Luang Nam Tha Province: Nam Ha) ( Figures 75, 76 View Figures 75, 76. 75 ).
Draconarius tabularis sp. nov.
( Figures 66–74 View Figures 66, 67 View Figures 68, 69 View Figures 70–74 , 75, 76 View Figures 75, 76. 75 )
Type material
Holotype female from Ban Tavan , Luang Nam Tha Province, Laos, 20 ° 58.7029N 101 ° 28.686 E 581 m, 20 ° 58.8729N 101 ° 28.8759E 657 m, valley with stream, disturbed primary forest, by hand, sieving, sweepnet, P. Jäger & V. Vedel leg., 9 November 2004, deposited in SMF. GoogleMaps
Etymology
The specific name comes from the Latin word ‘‘ tabularis ’’ meaning ‘‘of plates’’, referring to the plate-shaped spermathecal tubes; adjective.
Diagnosis
This new species can be easily distinguished from other Coelotinae by the absence of epigynal teeth, the indistinct atrium, the posteriorly situated epigynal hoods, and the
unique spermathecae extending and looping anteriorly and forming plate-shaped spermathecal tubes ( Figures 66–69 View Figures 66, 67 View Figures 68, 69 ).
Description
Female paratype. Small spider, total length 4.50 mm ( Figures 72–74 View Figures 70–74 ). Dorsal shield of prosoma 2.35 long, 1.42 wide; opisthosoma 2.15 long, 1.34 wide. AME smallest, approximately half the size of other eyes [AME 0.04, ALE 0.08 (left ALE missing), PME 0.07, PLE 0.08]; AME, ALE, PLE close together, separated by about AME diameter; PME separated from each other and from AME by slightly less than PME diameter, from PLE by slightly more than PME diameter (AME–AME 0.04, AME– ALE 0.04, PME–PME 0.06, PME–PLE 0.08, AME–PME 0.05) ( Figure 71 View Figures 70–74 ). Chelicera with three promarginal and two retromarginal teeth. Epigynum without epigynal teeth; atrium small, situated posteriorly, with barely visible atrial margins; epigynal hoods distinct, situated posteriorly close to epigastric furrow; copulatory ducts indistinct; spermathecae with small bases, separated by approximately its
width; spermathecal stalks (could be the heads) extending anteriorly, then strongly looping and forming plate-shaped broad structure ( Figures 66–69 View Figures 66, 67 View Figures 68, 69 ).
Male. Unknown.
Relationships
Draconarius tabularis sp. nov. is considered congeneric with the type species of the genus Draconarius as it exhibits two retrolateral cheliceral teeth. However, the posteriorly situated epigynal hoods and the unique course and shape of the spermathecal tubes make a definite generic placement questionable. No similar species has been described so far.
Distribution
Laos (Luang Nam Tha Province: Ban Tavan) ( Figures 75, 76 View Figures 75, 76. 75 ).
