DIALEUROLONGA Dozier

Dialeurodes (Dialeurolonga) Dozier, 1928: 1001 . Type species Dialeurodes (Dialeurolonga) elongata , by original designation and monotypy.

Dialeurolonga Dozier ; as full genus, Takahashi, 1951: 354.

DIAGNOSIS AND COMMENTS. As interpreted here, Dialeurolonga comprises species with the following combination of characters: with internally toothed tracheal pores (sometimes indented so shallowly as to resemble tiny invaginated combs) at tracheal openings at margin; vasiform orifice cordate, usually rather elongate, operculum not fully occupying orifice; lingula head usually distinctly lobulate, at least partially exposed but included within vasiform orifice; sometimes with submarginal tubercles (which are lacking in the similar genus, Dialeurodes ); ventrally, thoracic and/or caudal fold stippled, often characteristically marked by transverse lines of tiny tubercles or spinules. Dialeurolonga was originally proposed as a subgenus of Dialeurodes . Although it was raised to full generic status by Takahashi (1951), it remains a genus somewhat unsatisfactorily defined, with the characters above being a synopsis of the author’s current understanding. However Jensen’s (1999, 2001) cladistic studies of Dialeurodes sensu lato indicate the complexity of the whole Dialeurodes group.

Most of the 48 described Dialeurolonga species are from the Ethiopian, Malagasian and Oriental Regions, but species from South East Asia, Australia and the Pacific Region

have also been assigned to the genus, with varying degrees of doubt. A single species from Belize is here described and is considered to be morphologically close to several species from the Old World tropics. There is also material from Costa Rica and Panamá (BMNH) tentatively placed in Dialeurolonga .
