Leonard, M. Leonard, C. Richart, R. M. Pyle, and K. Novoselić. Diagnosis: See under preceding species. Etymology: The species name honors Robert Michael Pyle, a notable lepidopterist, author, conservation advocate, and as is this species, denizen of the Willapa Hills. Description: Male: Length, 5.0 mm. Fourteen ocelli in oval-triangular group. Metazonital shoulders poorly developed; segmental setae curved, acute. Legpairs one, two reduced, pairs three, four encrassate, pairs five to seven near same size as postgonopodal legs; femora three, four with basal femoral knobs acute, posteriorly directed.Anterior gonopods (ag, Figs. 244, 245) with large anterior sternum, widely separated, curving lateral to posterior gonopod coxites, apically decurved but without any apical expansion, small lateral branch tightly appressed to gonopod (free in Fig. 245 due to compression on microscope slide). Posterior gonopod telopodites reduced but relatively larger than in L. evergreen; posterior gonopod coxites (pgc, Figs. 244, 245) short, broad, anteriorly cupped, with broad, lamellate process mesally, basal pseudoflagellum originating posteriorly, two processes distolaterally, more lateral process composed of filaments (seen as separate in Fig. 246 due to compression on microscope slide), mesal process curved, apically fimbriate.

Diagnosis. This species differs from the sympatric M. colombizona by about 10% mean divergence in the barcode (Fig. 1), as well as the wing shape (Fig. 24). The most similar barcode is that of M. winnizona, from which it differs by 6.8% minimum p-distance (Fig. 1, Table 1). This species is in the BOLD as BOLD:ADV9367. Distribution. Colombia. Etymology. Named for Paul Hebert, who has kindly helped the senior author with barcoding issues.Published as part of Brown, Brian V., Hartop, Emily A. & Wong, Maria A., 2022, Sixteen in One: White-Belted Megaselia Rondani (Diptera: Phoridae) From the New World Challenge Species Concepts, pp. 1-17 in Insect Systematics and Diversity 6 (3) on page 11, DOI: 10.1093/isd/ixac00
One-Parameter Semigroups Generated by Strongly M-Elliptic Pseudo-Differential Operators on Euclidean Spaces
No full textWe begin with a recall of the definitions and basic properties of the standard Hörmander classes of pseudo-differential operators on Rn. Then we introduce a new class of pseudo-differential operators that can be traced back to Taylor, generalized by Garello and Morando and further developed by M. W. Wong. A related class of pseudo-differential operators depending on a complex parameter on an open subset of the complex plane is constructed. We tease out from this related class the strongly M – elliptic pseudo-differential operators and prove that they are infinitesimal generators of holomorphic and hence strongly continuous one-parameter semigroups of bounded linear operators on Lp(Rn), 1<p<ꚙ. The proof is based on careful refinements of the Agmon – Douglis – Nirenberg estimates for the pseudo-differential operators in the book by M. W. Wong. In the case when p=2, we give another proof that strongly (ρ,Λ) – elliptic pseudo-differential operators, which include strongly M – elliptic ones, are infinitesimal generators of strongly continuous one-parameter semigroups of bounded linear operators on L2(Rn) by first proving Gårding’s Inequality for strongly (ρ,Λ) – elliptic pseudo-differential operators on Rn
