Diagnosis

Sexual dimorphism absent, except for terminalia. Vertex slightly exposed. Ocellar spots present. subcampaniform, posterior margin slightly produced mesally. Micropterous: tegmina reduced to pads wing absent. Forefemur type A 2 (stout proximal spines followed by terminating in apical spines).

hind femur strongly armed. Tibia dorsoventrally flattened. Hind metatarsus longer than succeeding

HISTORY of metanotum unspecialised. First abdominal tergite simple, without setose gland. Sixth and abdominal tergites covered with minute setae. Seventh abdominal tergite medially produced, much of the supra-anal plate. Supra-anal plate symmetrical. Cerci apically pointed. Subgenital plate trical, interstylar margin weakly transverse. Style short, similarly sized, apically minutely pointed genitalia: L1 divided, distal part densely covered with scutes; L3 scythe-like, with distinct sub-apical L4C broad, with row of spines on inner margin; L4D broad; L4G basally rounded, with posterior apically rounded; R1H with apical spine; R2 anteriorly with deep-mesal invagination. R3 triangular, rounded.

Females similar to males except for terminalia. Spermatheca (sp) branched, the leading duct very the branching duct relatively long, apically rod-shaped. Laterosternal shelf (l.s.) broad, rectangular, nous except margins; Posterolateral extension membranous, triangular. Subgenital plate symmetrical

Calcistylopyga differs from Dorylaea in terms of being micropterous (tegmina and wings developed Dorylaea ) and the posterior magin of seventh tergite medially produced covering the succeeding (posterior margin of seventh tergite not produced in Dorylaea ).

Calcistylopyga is superficially similar to Austrostylopyga but differs in terms of sclerotised L1 sclerotised in Austrostylopyga ), R2 anteriorly with deep-mesal invagination (R2 broad without anterior invagination in Austrostylopyga , referred as R 3 in Mackerras 1968), and spermatheca with leading short, the branching duct relatively long, apically rod-shaped (leading duct relatively elongated and bulbous, while branching duct elongate and apically pointed in Austrostylopyga ); from Miostylopyga in tegmina reduced to pads (tegmina absent in Miostylopyga ), and the presence of arolium, and tarsomeres 1–4 and arolium (arolium absent, and pulvilli only on tarsi 3–4 on Miostylopyga ).

Etymology

Feminine. A combination of ‘ Calci ’, referring to the karst landscape where they were usually found ‘ stylopyga ’ in reference to the micropterous/apterous blattids.
