UNDESCRIBED SPECIES OF JAPANESE TIPULIDAE(DIPTERA). PART II *By Charles P. Alexander
U. S.A.
Amherst.Massachusetts'
The initial part under this general title was published in the Transactionsof
the shikoku Entomological Society, vol. 6, Pars 1, september 1958. At this time
I am discussing further materials that were taken in Honshu by Dr. Kintaro Baba,
with fewer speciesfrom Honshucollectedby Toshio Mishima and others from Shikoku
and Kyushu by Syuti Issiki and Syusiro Ito in 1950,1951 and t952. I expressmy
sincere thanks to all of the above for these interesting speciesof crane flies.

Marcb. 1969and stout, ipex obtuse; inner style rougbly semiovalin outline, both the beak andlower beak very short, blackened,outer margin with a low darkenedglabrousflange,
the anterior end of which is producedinto a short black spine; at base of styleon outer margin with a collarlike flange providedwith numerouscoarsesetae. Phallosome,p, dilated at base,bent strongly dorsad and finally caudad,terminating ina slenderstraight blackenedspine.

6 9. July 8-13,1954.
This interesting species is named for Dr. Kintaro Baba to whom I am indebted
for many JapaneseTipulidae and who has greatly increased our knowledge of t.hecraneflies of Honshu. The fly is quite distinct from the three other regional membersof
the genus, being most similar to Macgregoromyia itoi Alercrnder and M. shihohuana
Alexander, differing evidently in the distinctive structure of the male hypopygium.
Tipula(Pterelaehisus)

seticellula glabricellula

subsp. nov.

O .- Length about 16.5-17mm; wing 16.5-18.5mm; antenna about 4.4-4.7mm.
Generally similar to typical seticellula Alev,ander,differing most evidently in thegreat reduction to total loss of macrotrichia in the wing cells. In the holotype thesetrichia are lacking. Correlated characters in the male hypopygium are found in the
inner dististyle, particularly the outer basal lobe which appearsas a broadly flattened
blade that forms a scooplike structure, its apex slightly produced. In typical seticellula
this lobe is a simple flattened blade, elongate-oval in outline, tip narrowly obtuse,
the surface with scattered trichia.

A specimen from Mount Tsurugi, Awa, Shikoku, taken June 5, 1950by Issiki and
Ito has a few tricbia in the outer wing cells, almost all in ceU Rs.
Antocha \Antoeha) subdentifera sp. nov.
Close to dentifera (wing of male 4 mm or less) ; generalcoloration gtaY,praescutum with three broad dark brown stripes; rostrum yellow; antennaeshort; malehypopygium with tergite narrowly transverse,setae relatively sparse,including those of
the central third; gonapophysisslender, the apical point longextended, tip acute.
6 .- Length about 3.2-3.5mm; wing 3.5-4mm; antennaabout 0.5-0.6mm.
Rostrum yellow, palpi brown. Antennae dark brown througbout, short; flagellar
segmentsoval, the terminal one slightly longer than the penultimate. Head brownish
gray.
Praescutum chiefly dark brown, lateral borders gtay, disk with three dark brown
stripes that are confluent or virtually so, posterior sclerites chiefly dark brown.
Pleura dark brown. Halteres with stem pale, the large knob dark brown. Legs withcoxae and trochanters. testaceous, fore coxae more darkened; remainder of legs pale
brown, outer tarsal segmentsslightly darker; claw of male with a single long subbasd

spine. IVings (Fig. 3) grayish subhyaline,prearcularfield whitened; veins pale brown.
Macrotrichia of outer veins sparseand scattered,including a series on outer half ofeach of Rr+oand Mr*r. Venation: R2 very faint to virtually atrophied; m-cu before
fork of M, in cases to about one'third its length.
Abdomen brown, subterminal segments darker brown to form a broad ring. IMale
hypopygium (Fig. 4) much as in dentifera in the conspicuousspineof the outer dis'tistyle, differing in various details. Ninth tergite, f, narrowly transverse,posteriorborder generally truncate but membranousand the outline difficult to determine;
cephalic margin less convex than in dentifera; setae of disk relatively sparse andscattered,including the central area. Outer dististyle, d, with the lateral spine shortly
beyond midlength. Gonapophysis,g, slender, apical points longextended,tips acute.
ln dentifera (Fig.5) cephalic border of ninth tergite, f, more convex; setae of
disk morenumerous,especiallya concentratedgroup on central third. Outer dististyle,d, with spine at or just before midlength. Gonapophysis,g, with extreme tip pale,less produced.
Holotype, '6, Kurokawa,Echigo, Honshu, September20, 1954 (Baba). Paratopotype,6,August 18, 1954.
This very small member of the genus undoubtedly is close to the larger Antocha(Antocha) dentifera Alexander, differing especially in the size and in details of hypopygical structure, particularly the tergite and gonapopbyses.

Orimarga(Orimarga) setilobofa sp. nov.

Size medium (wing of male about 6.5mm) ; generalcoloration of headand thorax
gray; rostrum, palpi and antennaeblack; halterespale yellow; legs brown; wings

mesally on proximal half and here with brushesof denseblack setae. Outer dististyle,d, long and slender,narrowed gradually to the acute tip; inner style fused at basewith outer, nearly as long and much stouter, distal half with conspicuousblack setae,

fewer on proximal part. Armature of phallosome,y', including three pairs or sets of
blades or spines,about as figured.
Holotype,6. Kurokawa,Echigo,Honshu,June 28, 1954 (Baba). Paratopotype,6.
Although it is similar in its general appearanceto other regional members of
the genus the present fly is well distinguished by the basal position of m-cu andespecially in the very distinct male hypopygium, particularly the vestiture of thebasistyle and inner dististyle. The most similar such species include Orimarga(Orimarga) pruinosa Alexander and O. (O.) yakushimana Alexander.

Holotype, '6, Yoshigahira,near Mount Sumon,Echigo,Honshu,600meters.June 25, L954
(Baba). Paratopotype,6.
Orimarga (Orirnarga) stenotesis most readily told from other regional species,
including O. (O.) firuinosa Alexander, O. (O.) setilobato sp. nov., and O. (O.) yakushimana Alexander, by the shape and venation of the wings, especially tbe very shortbasal section of Rr*o.
