Patelloceto secutor

description: Patelloceto secutor sp. n.   Figs 118, 119, 123–137  
 Etymology: From Latin secutor (a class of gladiator). The sharp dorsally pointed tibial apophysis that appears sword­like and is shielded by the palpal cymbium, is reminiscent of a gladiator armed with a sword and a shield.   
Diagnosis: The male can easily be recognised by the dorsal palpal tibial apophysis that is more than half the dorsal cymbium length, and the presence of a small finger-like retrolateral palpal tibial apophysis (Fig. 134). The female can be recognised by the two widely separated copulatory openings that are shielded by two oblique epigynal hoods that are bent and extended medially along their anterior margin (Fig. 136).  
Description:  
 Male.

Legs I to IV uniform orange to brown, femora dark brown; tibiae, metatarsi and tarsi with relatively dense scopulae ventrally; remaining segments covered in less dense setae; ventral cusps absent. Leg spination: femora: I pl 1; patellae and tibiae spineless; metatarsi: III vt 1. Palpal spination: tibiae pl 1. Epigyne with broad membranous median septum separating laterally placed spermathecae (Fig. 131); copulatory openings situated laterally, in same plane as ST II, flanked laterally by oblique epigynal hoods, anteriorly extending transversely to level of median margin of spermathecae (Fig. 136); copulatory ducts directed anteriomedially, bending sharply before running posteriorly to small bilobed ST II, connected by narrow duct to small oval ST I, not reaching epigastric fold (Fig. 137).
