PLATE 5. Markia espinachi Cadena-Castañeda n. sp. Male habitus (A); head and pronotum in lateral view (B); male abdominal apex in ventral view (C); head and pronotum in dorsal view (D). Scale bars 5 mm. Photos: C. Hernandez.

Description

Head: Fastigium straight and 0.8 times the length of prozonal spine. Ventral margin of the fastigium curved backward, dorsal margin undulated from the proximal to the mesal region. Scapus 3 times longer than the pedicellus. Thorax. Pronotum: pronotal disc with two elongated and flattened spines. Prozonal spine 1.3 times as long as the fastigium and curved forward, metazonal spine slightly longer and in lateral view almost three times as broad as the prozonal spine. Legs: fore femur cylindrical, ventral margin with a median spinule and in distal region with two external spines. Fore tibia with square cross-section and armed with two spines on the dorsal margin above the tympanum, ventral margin with four spinules. Middle femur with three ventro-lateral spines, spines of middle tibia organized as follows: two on the dorso-internal margin and two on the dorso-external margin of the proximal region. Hind femur slender and laterally flattened, armed ventrally with seven spines on external margin, increasing in size from proximal to distal end, internal margin with five spines arranged similiarly as the previous ones. Tegmina apex obliquely truncated. Abdomen: tenth tergite without modification. Male cerci pubescent, external branch 0.7 times longer than the internal branch, with sharp apex; internal branch with expanded base, apex with ventral edge denticulate and external edge branch strongly sclerotized. Subgenital plate with broad base, tapering toward the apex, with shallow u-shaped emargination, styli cylindrical.

Female: Unknown.

Measurements: Total length: 50–52, Pronotum: 8–8.8, Tegmina: 42–43.2, Fore femur: 8–9, Fore tibia: 9.2–9.8, Middle femur: 11–12, Middle tibia: 12–12.7, Hind femur: 27–28, Hind tibia: 35–36, Subgenital plate: 3–3.2, Cerci: 2.5–2.8.

Etymology: Dedicated to Carlos Espinach Phillips, for his contributions and efforts in respect of INBio in Costa Rica, thereby contributing to the conservation of fauna in this country. According to the original Spanish pronunciation it is suggested to pronounce the last syllable of the species name as the last syllable in “mariachi”.
