DESERT RECORDS. Map 10. Los
Angeles Co.: 2.5 mi SSW Valyermo, 4800', various dates, 8 July
- 9 Aug (N. McFarland; LACM). Riverside Co.: Juniper Flat, JTNP,
5 Aug. 1959 (E. L. Sleeper; LACM); Upper Covington Flat, JTNP, 5
Aug. 1959 (M. Knox & E. L. Sleeper; LACM); Lower Covington Flat,
JTNP, 22 July 1960 (M. Y. & R. D. Knox; LACM); Smithwater Wash,
JTNP, 23 July 1960 (E. L. Sleeper; LACM).
San Bernardino Co.: NW fork, Long Canyon, 2 July 1963 (E. L.
Sleeper; LACM).
DISCUSSION. This species is
marginal in our area. The worker and female are unknown, but possibly
are N. leonardi which has a similar distribution. It is easily
recognized by its small size, sickle-shaped mandible and the ocellar
prominence. It is most like N. mojave but that species lacks
the ocellar prominence.

RANGE: Western Mojave Desert south to Lower California.
DESERT RECORDS. Map 11. "Mojave Desert: [M. Smith, 1943a].
San Bernardino Co.: 1 _, 4 mi NW Adelanto, 2900', 18 Sept 1978
(RRS & CDG; LACM), found dead on ground.
DISCUSSION. This species has been previously known only from
the type specimens from an unknown locality in the Mojave Desert.
It is evidently nearest to N. minor and superficially looks much
like that ant. However, the ocelli are much smaller and are not
placed on a prominently raised area.
The recently described N. nyensis Watkins of Nevada may be
the worker form of this species.
