INTRODUCTION
Since the publication of the small paper by HAMALAINEN & MULLER
(1989), describing Teinobasisannamaijae from Mindanaoand Dinagat, I have
collectedorreceived plenty of new Teinobasis specimens from differentislands
ofthe Philippines; at present my collection ofPhilippine dragonflies contains
over 500 Teinohasis specimens belonging to atleast 9 differentspecies.
Adistinctnewspecies recently foundfromSierraMadremountainsinnorthern
Luzon is describedhere. Since it seems to be relatedto T. samaritisRis, 1915,
thepresentbriefdescription mainly pointsoutthedifferencesofthesetwospecies.
The new species is dedicated to my friend and collaborator of many years, Dr Matti
Hamalainen (DepartmentofAppliedZoology,University ofHelsinki, Helsinki, Finland).

MALE: Head. — Colouring as in T. samaritis, but margins oflabrummore
broadly ochreous.
Thorax. — Similarly colouredas inT. samaritis; dullolive greenacquiring
a whitish blue pruinescence lower on the sides. Ventral surface pale greenish
yellow with whitishblue pruinescence.
Wings. — Stemoftheveins R4+5and IR3completely fusedforthelength
ofone cell and theveins arising slightly distally to the subnodus exactly as in
T. samaritis. Ac situated much nearer to Ax1 and Ax2.
Abdomen. — The colourpattern on segments 1-7 resembles that of T.
samaritis. However, the dorsal darkcolouring is moreintense, itextends some-
what more downwards onthe sides, and the contrast with the lateral greenish
blue on the sides of segments 1-2 is more profound. Segments 8-10 blue on
sides. Dorsum ofsegment 8 with apeculiarly shaped black stripe, whichgives
animage ofa candlebeing placed upside down in a candleholder.Apical ring
on segment9broadening alittlebasalwards on dorsum. Dorsum ofsegment 10
broadly black.
Anal appendages shaped as in Figures 1-2. Upper branch of the superior
appendages triangularly pointed in dorsal view and in lateral view resembling
anear lobe.
Measurements (mm). — Hind wing24-25, abdomen39-40.
female. — Amuchstouterinsectthanthemale,whichitresemblesincolouring.
Notable differencesare the almost wholly ochreous labrum and the different
colour pattem of segments 8-10, which are broadly black dorsally and pale
coloured on the sides similarly to the more basal segments. The apical three
segments are clearly stouter than inT. samaritis female.
Measurements (mm). — Hind wing26,abdomen40.

DISCUSSION
The differentshape ofthe upperbranchofthesuperior analappendages enables
aneasy separation ofthe maleofT. hamalainenisp. n. fromT. samaritis, which
is themost widespread species ofthegenus inthe Philippines. Maleappendages
of T. samaritis have been illustrated by RIS (1915), NEEDHAM & GYGER
(1939)and in the most detailed form by LIEFT1NCK (1974).
A complete revision ofall Philippine species ofthe genus is necessary, espe-
cially to provide means to identify solitarily collected females correctly. So far
13 Teinobasis species have been described from the Philippines. T. combusta
(Selys, 1877)was erroneously listedas a Philippine species by HAMALAINEN
& MULLER(1989).However,according toLIEFTINCK(1935),thetypelocality
ofcombusta given inSELYS LONGCHAMPS (1877) as ”Sulu” should infact
beSoela (Sula)Island.LIEFTINCK (1935)also puts comhusta in synonymyof
T. lorquini (Selys, 1877), a fact not taken intoconsideration inthe recent world
lists ofOdonata.
