Duchailluia

Duchailluia
A new member of the subfamily Blattinae and related to Blattina Hebard, Blatta
Hebard, Blatta Linnaeus, Dorylaea Stal, and Neostylopyga Shelford, but 
more nearly related to the latter than to any of the others. From the genotype 
of Neostylopyga, i.e., N.rhombifolia (Stoll), the present asemblage can be 
seperated by the less decided development of the arolia between the tarsal claws,
the even simpler, completely corneous and non-veined lateral lobiform tegmina 
in both sex, the nono-divided distal tergite (supra-analplate) of the male and 
the unusual bifurcate styles of the distal sternite ( subgenital plate) of the 
same sex. The new genus agrees with Neostylopyga in its general form, similarly 
reduced tegmina in bothe sexes, non-specialized median segment of the male and 
robust limbs.
== General Description ==
Form elongate ovate, depressed. Head cordiform, interspace between eyes very board
in both sex, in profile elongate subtrigonal. Pronotum trigono-trapezoidal in 
outline. Tegmina lateral, abbreviate, lobiform, completely corneous, without 
venation. Wings absent. Dorsal surface of abdomen and median segment simple and 
unspecialized in both sexs. Distal tergite ( supra-anal plate) of male undivided,
of female emarginate at apex. Distal sternite (subgenital plate) of male with 
interstylar margin emarginate; styles nearly straight, distad acute, with a 
distinct brief median bifurcation on internal side. Cephalic femora with ventro-cephalic
margin having two distal spines longer and more strikingly developed than remainder
of series. Ventral margins of median and caudal fermora regularly and strongly
spined. Caudal tarsi with metatarsus at least equal in length to reminder of tarsus,
Ppulvilli apical; tarsi with articles one (cephalic) to three (caudal) biseriately
spinulose ventrad. Tarsal claws long, equal in length, margins unspecialized, arolia
present but very small.
