Abstract

Aleuropleurocelus hyptisemoryi Gill sp.n. (Hemiptera: Aleyrodidae) and its parasitoid, Encarsia heratyi Polaszek sp.n.

(Hymenoptera: Aphelinidae) are described. Both species are known so far only from desert lavender (Hyptis emoryi) in

California, but are likely to be more widely distributed. Encarsia heratyi, a member of the Encarsia parvella-group, is

separated from apparently closely-related species in that group.

Introduction

During surveys of vegetation in the Philip L. Boyd Deep Canyon Desert Research Center in California (http://deep-

canyon.ucnrs.org/) in March 2009, populations of a whitefly with dark-bodied puparia (Hemiptera: Aleyrodidae)

were found to be abundant on desert lavender, Hyptis emoryi (Lamiaceae). Up to a month after collection and stor-

age in dry, sealed containers, several parasitoid wasps emerged from some of the whitefly puparia. J.H. Martin

(Natural History Museum, London) identified the whiteflies as an undescribed species of Aleuropleurocelus Drews

& Sampson. This material was forwarded to the second author for comparison with conspecific material from pre-

vious collections, and with related species. The parasitoids were identified as an undescribed species of Encarsia

(Hymenoptera: Aphelinidae) belonging to the parvella-group. Both species are described below.

Hemiptera: Aleyrodidae

Aleuropleurocelus Drews and Sampson 

Martin & Mound (2007) listed 12 described species in the genus, mostly endemic to California and the American

southwestern deserts but also known from Mexico, Florida and Brazil. Dooley (2010) recently described another

species, Aleuropleurocelus nevadiensis from the U.S. Several undescribed species are known from California and

Nevada in the U.S.A., and Martin (2005) listed 10 undescribed species from Belize. Eight of the thirteen described

species, from California and Mexico, were described in works by Sampson (1945), Drews & Sampson (1956,

1958) and Sampson & Drews (1941). Four of the twelve species were originally assigned to the European genus

Tetralicia, but these have been placed now in Aleuropleurocelus. The similarities between these two genera are

based primarily on the position of the true margin of the puparia (4

th

 instar), which is rolled down and inwards, and



is not visible in dorsal view. Martin (2005) discussed current ideas on the relationship between Aleuropleurocelus

and  Tetralicia. The new species described here was found in southern California at several desert localities, all
