DIAGNOSIS. Confront to general characteristics of AELURILLINES which have the whole bulbus covered by opaque sclerotized tegulum and a coil of embolus hidden behind anterior part of tegulum, from where only its tip protrudes. Bulbus usually ends posteriorly by sharp pointed triangle, sometimes with narrow "tail". There is often also a small, conical protuberance ("bump") on tegulum. Tibial apophysis is short and robust, sometimes sclerotized and hook like, often accompanied dorsally by fleshy protuberance. Female epigyne, usually in a form of sclerotized flat plate, with indistinct, small copulatory openings, but often with sclerotized "wings" or edges, sclerotized chambers of spermathecae in a form of a pair of compact bodies with convoluted internal chambers, or a chain of irregular chambers. Copulatory ducts are sclerotized, or short and indistinct, even invisible.
Phlegra departs from the above l-arger group's definition by shape of epigyne and spermatheca, and also by tibial apophyses. Epigyne is plate-like, with two large, oval, or distorted oval-like depressions. Copulatory openings are hidden under anterior rim of depression, ducts run ahead, often funnel-like, next passing into sclerotized spermathecae, which are bent sausage shaped, with numerous internal chambers. The ducts and spermathecae are comparable in several genera, but length of spermathecae different: in Asianellus (spermathecae short), Phlegra (spermathecae of middle length) and Langona (spermathecae very long), the number of internal chamber being proportional to the length of spermatheca. In males tibial apophysis consist of two rami separated by a narrow gap, in species in which both rami are pointed the dividing gap is narrow, "V" shaped and, incidentally, their embolus is longer and stretches outside tegulum along groove on tip of cymbium. In species in which dorsal ramus is blunt, the gap is broader, "U" shaped, its walls are parallel, tip of embolus is flattened plate-like, shorter and broader. In species with black cymbium the observation of shape of black, sclerotized tibial apophysis may be difficult and require separation of cymbium from tibia. Body color pattern includes either prominent white stripe along abdomen and two stripes along thorax, or is gray with two lines of darker spots along abdomen. The clypeus is striking by having contrasting white setae.

Judging from published drawings palp resembles Aelurillus, but differs by broader embolus. Epigyne resembles externally Aelurillus, with two sclerotized semiarches anteriorly, but its internal structures are different: copulatory ducts are thickwalled and run marginally along the whole length of epigyne, spermathecae small, located posteriorly, their internal structure is not clear. Species seem to differ by facial pattern of dark and light areas, eyes anterior lateral are relatively large and located just above level of anterior median ones (see figs 5-12 in the original descriptions - reproduced below). Diagnostic drawings below are integral part of definition.
