Cynips (nubila) lanaris, new species
Agamic form

GALL.—Central core red-brown, densely covered with short, hair-like cells most of which are swollen at tip. Long, hair-like spines forming body of gall light straw white, tinged yellow; bases of these spines almost never swollen; these spines wavy for their whole length and densely set. Galls appear as loose tangles of hairs.

HOST. — Quercus sacame [arizonica]. This is the largest tree among the evergreen white oaks of the region.

RANGE.—Tamaulipas: Miquihuana, 7 SE, 6000'. Possibly extending for some distance through a more northern end of the Eastern Mexican Sierra, east of the main divides.

LIFE HISTORY.—Adults ; December 10.

In our previously published revision of this complex (Kinsey, 1936, Ind. Univ. Sci. Ser. 4:243-258) we reported on nine species: two from southeastern Arizona, and seven from Mexico. Six of the Mexican species were from the Western Sierra and from the more southern Cordillera. Only one species, nigricula, was described from the Eastern Sierra—from the eastern part of San Luis Potosi. North of that point the Eastern and Western Sierras are widely separated, and this may explain the comparative rarity of the nubila complex in the Eastern mountains of Mexico. To the previously described list of species, however, we can now add two from this Eastern Sierra—one from northern Hidalgo, and one from southern Tamaulipas; but north of these norther- most localities there are still 400 miles of Eastern Sierra in which we have not found this group.

In the previously published key to this complex (Kinsey 1936:246- 247), the two species here described would run to sections 7 and 8; and the phylogenetic relations of the present species are clearly with incompta, nigricula, and chica, which appear in those sections of the key. This now gives us 5 species which have the parapsidal grooves continuous to the pronotum. As their geographic positions would lead one to expect, the present species are closest to nigricula and incompta.

We have lanaris from a locality near the southern end of the boundary between Tamaulipas and Coahuila. Lanaris is most closely related to the more southern species molucrum (described in the present paper). Lanaris differs chiefly in having the central core of the gall covered with hair-like cells, most of which are swollen at the tips. The galls of lanaris and nigricula are essentially the same. From incompta, lanaris is to be distinguished by the darker thoracic lines, the darker abdomen, and the vein-like form of the infuscation on the first abscissa. The galls of the two species are essentially the same.
