Scotinella tinikitkita new species

( Fig. 102 ab)

Description: Female: Total length 3.10 mm. Cephalothorax 1.30 mm long, 1-10 mm wide, 0.80 mm high. Abdomen 1.80 mm long, 1.25 mm wide, 1.31 high. Cephalothorax red with blackish gray flecks, thin black eye margins, moderately attenuate apically except the anterior end of clypeus. Fovea black and longitudinal with three to five striae emanating from it. Eight eyes in two rows, all clear, straight AE shorter than the straight to slightly procurved PE. Eyes diameter (mm): AME = 0.09, ALE = PME = 0.08, PLE = 0.05. Eye separation: AE equidistant from each other, as long as 0.5 ALE but less than 0.5 AME diameter, ALE-PLE as long as one PLE diameter, PME-PME a little over one AME diameter, PME-PLE shorter than one AME but as long as one PME diameter. Median ocular quadrangle a little narrower in front than behind, posterior width equal to length. Clypeus height relatively large, 1.4 times AME diameter. Sternum reddish brown, longer than wide, and midanterior border with a truncated cavity for the base of labium, lateral margin between coxae extended to the venter of carapace, posterior end connected to the pedicel. Labium same color as maxillae and sternum, longer than wide, posterior end a little broader than the anterior end, with a median cleft. Maxillae longer than wide, retromarginal side constricted at midlength just above base of pedipalp, distal end with a whitish circular area bearing scopulae. Chelicerae small and robust, swollen after the constricted base a little below clypeus, promargin with three teeth in increasing size apically, and retromargin with seven small teeth. Legs relatively short, reddish becoming reddish to brown yellow in the metatarsi and tarsi, apex of tibia white. Ventral spination in tibiae I = 15 (seven pairs + one), II = ten (five pairs) and metatarsi I = ten (five pairs) and II = nine (four pairs + one). Metatarsus I/tarsus I = 2.22. Longest dorsal trichobothria in tibia III ca. one third tibial length, borne in its basal one third, in tibia IV at midlength and longer than one half of its length; in metatarsi III-IV borne above its midlength and as long as one third metatarsal length; in tarsi III at the middle, equal to one half of tarsal length, tarsus IV anterior to midhalf and about one third of tarsi. Tarsi two-clawed, each claw with two teeth. Tarsal claw tuft sparse. Leg formula 1423. Pedipalp as long as combined length of patella I and tibia I, venter of femur with four spines and dorsum of tibia with four posteriorly curved trichobothria.

Length of leg and pedipalp segments (mm):

Abdomen subglobular, reddish brown, scutum occupies more than one half abdominal dorsum, and the rest is membranous, extended laterally and ventrally, except epigynal area and around it. Spinnerets almost uniform in size, anterior pair slightly larger than the posterior. Epigynum lightly sclerotized in the middle except lateral margins, tooth-like with cleft distal end and small longitudinal slit posteriorly touching epigastric furrow.

Etymology: Named after the spine pattern in tibia and metatarsi in Tagalog: ‘tinik’ = spines and ‘kitkit’ = adheres closely to a surface.

Natural history: All three females were collected from kerosene light trap sample in April and July.
