Alaeho linoi new species

( Fig. 97 a-d)

Description:

Male: Total length 4.00 mm. Cephalothorax 1.75 mm long, 1.40 mm wide, 0.90 mm high. Abdomen 2.25 mm long, 1.28 mm wide, 1.00 mm high. Cephalothorax reddish brown, moderately attenuated anteriorly, serrated laterally except the posterior end. Eight eyes in two transverse rows, all clear except the slightly whitish PME. AE shorter than the straight PE, slightly recurved dorsally to slightly procurved when viewed frontally, ALE moderately elliptical like PME and very close to AME. Eye diameter (mm): PME = 0.13, ALE = 0.12, AME = 0.1 1, PLE = 0.10. Eye separation: AME-AME 0.4 times eye diameter, AME-ALE one eleventh of one AME diameter, PME-PME one third AME diameter, PME-PLE one half AME diameter, ALE-PLE 0.7 times AME diameter. Median ocular quadrangle narrower in front than behind, length as long as posterior width. Clypeus height small, 0.7 times AME diameter. Sternum same color as cephalothorax, punctate with lateral margins between coxae extended to the venter of carapace, midanterior margin with a wide concavity for the base of labium, posterior end broadly blunt between coxae IV. Labium as long as wide, broadest basally, and distal end with a median cleft. Maxillae same color as labium and sternum, longer than wide, outer lateral margin not excavated for the pedipalp, distal end almost entirely occupied by the scopulae. Chelicerae reddish to reddish brown, midhalf swollen dorsally/frontally and constricted basally. Promargin bears no teeth except scopulae. Retromargin with three teeth. Legs relatively long and slender, light reddish brown becoming brownyellowish in the metatarsi and tarsi. Spination in femora I = 0-0-1-0, II = 0-0-0 0, III = 1-1-0-0, IV = 1-0-0-0, tibiae I = II = 0-0-0-0, III = 0-0/2-1-0, IV = 0-0/2-0-0; metatarsi I = II = 0-0-0-0, III = 0-0/1-1-0, IV = 0-0/1-0-0. Metatarsus I/tarsus I = 1.26. Tarsi twoclawed, each claw with zero to four teeth, claw tuft clubbed. Leg formula 4123. Pedipalp longer than combined length of femora II and patella II, retrolateral tibial apophysis porrect and sharp with its length as long as tibial diameter, tibial promargin with two long setae and a dorsal one. Membranous conductor short, similar to the median apophysis.

Length ofleg and pedipalp segments (mm):

Leg	Femur Patella Tibia Metatarsus Tarsus Total
1	1.50	0.75	1.30	1.20	0.95	5.70
2	1.25	0.60	1.05	0.93	0.78	4.61
3	1.10	0.45	0.80	0.90	0.73	3.98
4	1.80	0.70	1.45	1.65	0.95	6.55
Pedipalp 0.60		0.35	0.39	-	0.60	1.94

Abdomen flattened, dorsal and ventral with shieldlike plates (scutum) separated laterally by a membranous layer extended circularly around the spinnerets. Epigastric growth and book lung opening very prominent. Posterior spinnerets more robust than the anterior pair, separated basally by one third its diameter. Median spinnerets visible ventrally. Anterior spinnerets far apart, the distance in between as long as one anterior spinneret.

Etymology: Dedicated to the collector Mr Lino Calces, one of our former collaborators, in slash-and-bum upland rice in Siniloan, Laguna.

Natural history: Handpicked from fallen decaying bark of a log stump in the middle of an Azucena ricefield in August.

Material examined: PHILIPPINES: Luzon Is., Laguna Prov., Siniloan, Magsaysay Vill ., holotype male, 22 August 1984, Lino Calces .

Distribution: Philippines.
