Female (figs. 1--2): Podosoma plate with 10 setal pairs, V absent, and unusuallyhaving a pair of circular incrassation (about 12μ in diameter) near posterior margin.Opisthosomal plate narrow and long, bearing 7 setal pairs, S_8 minute, S_6 and M_(10-11)verysmall, M_11 smaller than M_(10). About 45 pairs of setae on the unarmed dorsum. Sternal plate with strongly sclerotized band on posterior margin, St_(1-3) and MStsubequal in length. Epigynial plate without median protrusion of anterior margin.Anal plate elongate pyriform. About 50 setal pairs on the unarmed venter. All thesetae needle-like, stronger on dorsum, setae on the posterior margin stout and long,sword-like. Peritreme reaching the anterior margin of coxa Ⅱ. Male (figs.3--4): Dorsal Plate entire, with 10 setal pairs, having a pair of circularincrassation in the midddle of plate. Unarmed dorsum bearing 16--17 pairs of setae. Ventral armature undivided, 3 pairs of sternal setae subequal in length, ventralportionton about 10--12 setae, may arranged asymmetrically. About 20--22 pairs of setaeon the unarmed venter. Peritreme ending in anterior margin of coxa Ⅱ. Holotype (?), allotrpe (?), paratrpes (1 ?, 2 ?, 8 protonymphs) collected off3 Taphozous melanopogon Temminck, 1841 Guangxi Autonomous Region. Specimensare deposited in the Department of Parasitology, Guiyang Medical College. In most Steatonyssus species there are 11 or more pairs of setae on the podosomalplate. The new species has only 10 pairs of these setae. Other species bearing the samenumber of setae are benoiti Till et Evans, evansi Delfinado, hubli Hirgaudar et Bal,and sudanensis (Hirst). However, the number of setal pairs on their opisthosomalplate is 5 in benoiti and sudunesis 6 in evansi 18 in hubli, and 7 in the new species.Moreover, the dorsal plate of megaporus, sp. nov. is ornamented uniquely with a pairof circular incrassation and its protonymph bears a pair of very large stigma.Read More
