Discussion. Bothaella is a polythetic genus diagnosed as follows ( Reinert 1973). Females by the combination of head with only broad, decumbent scales on vertex; erect forked scales restricted to occiput; antennal pedicel with large patch of broad, silvery scales on dorsal, mesal and ventral surfaces; acrostichal setae absent; anterior and posterior dorsocentral setae well developed; upper proepisternum with 2–4 setae, lower proepisternum bare; mesokatepisternum with 1,2 upper and 1,2 lower posterior setae; and mesepimeron with 3–8 upper and 1 lower setae. Fourthinstar larvae by the combination of setae 5,6C long, stout and single; 4C moderately long, with 4–14 branches, inserted mesal and slightly anterior to 6C; 5C inserted posterior to 6C; antenna short, seta 1A short, with 2,3 branches; 13P well developed, with 4–21 branches; 6IVI long, aciculate, 6IVVI with 2 branches; 1VII long, stout, with 3–5 branches; 3VII short; 13VII far anterior to 10VII; 1X long, stout, with 2–4 aciculate branches, inserted near caudal margin of saddle; saddle incomplete ventrally; ventral brush with 8,9 single to 3branched setae; siphon with 12–17 evenly spaced, pecten spines; and seta 1S with 2–5 aciculate branches, inserted distal to pecten. The female and fourthinstar larva of alongi exhibit these diagnostic character combinations; thus, the species clearly belongs in genus Bothaella.
The female of Bo. alongi is similar in habitus to other species of the genus, cf. descriptions of Bo. eldridgei (Reinert) , Bo. helenae (Reinert) , and Bo. kleini (Reinert) in Reinert (1973) and Bo. brownscutuma (Dong, Zhou & Dong) in Dong et al. (1999) (we have not seen specimens of the latter species). The females of Bo. brownscutuma and Bo. kleini are unknown, but the female of Bo. alongi most likely can be separated from these two species by the white markings on the mid and hindtarsi. The female of Bo. alongi differs from those of Bo. eldridgei and Bo. helenae by the darkscaled postgena of the head and by the presence of generally fewer setae on the lateral thoracic areas. The fourthinstar larva of Bo. alongi can be distinguished from the other species by the branching of setae 4 C, 6I,II, 7I, 1VIII and number of pecten spines.
