Madates

Type Species:
Cimex limbata Fabricius, 1803, by original designation.
Included Species:
limbata
(Fabricius, 1803)

Comments:
The genus Madates is
currently monotypic with the only known species reportedly occurring from
southern India eastward through southern China, southeast Asia to Indonesia.
Examination of numerous specimens, however, has revealed that those
specimens from
southern India are distinct from specimens from southeast Asia and
Indonesia. After borrowing more specimens from several institutions,
two more species have been discovered from isolated areas in China.
This will bring the total number of species in the genus to four. |
Key to males of the genus Madates
1
Black spot on base of each juga continuing cephalad along lateral margin
of juga distinctly beyond apex of adjacent antennifer; transverse pale
band on apical third of each hemelytron broad mesially near apex of
scutellum, becoming narrower laterally; transverse sulcus on
posteroventral surface of pygophore interrupted medially by low tumescence |
new species no. 1 |
-
Black spot on base of each juga usually not extending cephalad beyond apex
of adjacent antennifer, in some specimens, this black spot does extend
forward, but only submarginally, the extreme lateral edge of each juga is
still pale; transverse pale band on apical third of each hemelytron of
nearly uniform width throughout; transverse sulcus on posteroventral
surface of pygophore not interrupted medially |
2 |
|
|
2(1)
Inner lobe of each paramere relatively robust short, not surpassing
lateral concave lobe, with four longitudinal ridges, apex obtuse; superior
ridge of pygophore not or only slightly produced caudad medially,
production if present very broad |
new species no. 2 |
-
Inner lobe of each paramere narrower, more elongate, usually surpassing
apex of lateral concave lobe, with three longitudinal ridges, apex usually
distinctly spinose; superior ridge of pygophore medially, production
narrow, obtusely triangular |
3 |
|

3(2)
Inner lobe of each paramere greatly elongate, nearly parallel sided, apex
obtusely spinose; anterior half of proctiger only slightly wider than
posterior half; transverse sulcus on posteroventral surface of pygophore
interrupted laterally by diagonal narrow ridge beginning near medial
excavation in inferior ridge and running ventrolaterad |
new species no. 3 |
-
Inner lobe of each paramere not as elongate, sides not parallel, but
rather tapering to sharply spinose apex; anterior half of proctiger
distinctly wider than posterior half; transverse sulcus on posteroventral
surface of pygophore uninterrupted laterally |
limbata (Fabricius) |
