Sphingius vivax View in CoL (Thorell, 1 8 9 7) ( figs 840-842 View Figs 837 , map 41 View Map 41 )

Thamphilus vivax Thorell, 1897: 233 , no figure, ♀, Burma, Moulmein.

Alaeho linoi Barrion and Litsinger, 1995 , fig 98a-f ♂, Luzon, Laguna Province; syn. n.

Note. — In the figure of the male palp of Alaeho linoi , the bulb is twisted relative to the cymbium over 180°.

Type material studied. — 1 ♂, 1 ♀. Burma, Moulmein ( MCSNG ).

Other material studied. — Malaysia, Gombak, Research station, 1 ♂, 1 ♀, lawn surrounded by secondary forest, in pitfall traps, l- 7.vii.1992, C.L. Deeleman ; PHILIPPINES, NEGROS, Paninbonan, Pandalikan cave , 1 ♀, 24.xii.1989, Theo van Es ; VIETNAM, Lang Son Province, 1 ♂ on the road Hanoi-Lang Son, 103 km from Hanoi , 21.iii. 1989, P. Beron ( AMNH) .

Diagnosis. — Dark brown, large-eyed species with distinctive epigyne. The carapace is rugose, with angular granulations along the margin. The posterior eye row is straight, the posterior median eyes are slightly angular, close together, nearly juxtaposed. The clypeus is rebordered, straight, the chilum has a rounded knob. Genital organs: the male palpal tibial apophysis is short and straight, pointed and parallel to the main axis, the tip of the cymbium is blunt obtuse, the embolus is almost straight and the median apophysis roundish in outline, with one small pointed protrusion. The anterior depression of the epigyne is wide, anteriorly rounded, slightly longer than wide, the spermathecae are large.

Description. — MALE (Gombak). Total length 4.00 mm. Carapace length 1.75 mm, width 1.30 mm, head width 0.80 mm; abdomen 2.00 mm long, 1.20 mm wide. Leg lengths: leg I 5.00 mm (1.30-1.80-1.00-0.90), leg II 4.20 mm (1.20-1.45-0.80-0.75), leg III 3.65 mm (1.00-1.20-0.80-0.65), leg IV 6.00 mm (1.60-1.90-1.55-0.95), palp 0.60-0.28- 0.28-0.60 mm. Carapace, mouthparts, sternum and abdomen deep chestnut brown, femora I-IV and tibia I brown, patellae yellow with distal dark ring, remaining leg segments orange. Carapace with small granulations ranged in radiating lines, margin with angular granules. Thoracic groove obsolete. Anterior eye row occupying 3/5 of head width, eyes close together, ALE a little larger than AME, PME a little larger than PLE, slightly angular and almost juxtaposed, 'A - 'A d from PLE. Clypeus smaller than 1 d AME. Chilum triangular with rounded knob when viewed from above. Sternum with small pits. Leg spination: femora I- III with 1-0d, femur IV with 1-1d, anterior tibiae and metatarsi spineless, tibia III with 1- 1v, tibia IV with 2-lv and 1-1rl; metatarsus III with 2-0v and 1-0pl, metatarsus IV with 1- lpv and 1-1rl. Tarsal claws on anterior legs with 5-6 teeth, posterior legs 2-3 teeth. Abdomen with short grooved collar and with almost entire dorsal and ventral scutum. Palp figs 840-841 View Figs 837 and diagnosis.

FEMALE (Gombak). Total length 5.60 mm. Carapace length 2.40 mm, width 1.80 mm, head width 1.08 mm; abdomen 3.40 mm long, 2.00 mm wide, epigyne 0.40 mm wide, 0.55 mm long. Leg lengths: leg I 6.90 mm (2.00-2.45-1.33-1.12), leg II 5.90 mm (1.70-2.00- 1.20-1.00). leg III 5.00 mm (1.40-1.60-1.15-0.85), leg IV 8.00 mm (2.10-2.70-2.00-1.20), palp 0.80-0.38-0.40- 0.72 mm. Carapace, eyes, mouthparts and leg colour as in male, femora almost as pale as the other segments, abdomen dorsally almost black, and white pre-anal spot lacking, ventrally mouse grey. Leg spination: femora as the male, tibia III with 2-2v, 0-1 pl, tibia IV with 2-2v and 0-1 rl; metatarsus III with 2-0v, metatarsus IV with 2-1v and 1-0pl and 1-1rl. Tarsal claws with less teeth than in the male. PMS with a double row of 4-5 cylindrical gland spigots. Anterior depression of epigyne rounded anteriorly, with parallel sides, a little longer than wide; spermathecae large and round, connivent. Vulva fig. 842 View Figs 837 .

Remark. — The specimens examined have larger eyes than the type specimen according to the original description (Thorell, 1897: 234) and in the description of Alaeho linoi . Other specimens of this widespread species may not have the contrasting leg colour as described for the Gombak male.

Habitat.— On open ground near the forest border. Has been seen running on open flat surfaces, even on water pools; has also been found in a cave entrance. Probably synanthropic, in gardens.

Distribution.— Myanmar (Burma), Malay Peninsula, Viet Nam, Philippines.
