Quindina horologium Betancourt-Caicedo , Pinto-da-Rocha, and Cabra-García

sp. n.

( Figures 1 , 3 , 4 , 10 )

Etymology

The species name reflects the dorsal pattern of emerald-green patches, which resembles an hourglass.

Type material

Holotype (MUSENUV-Ar-2229), adult male preserved in 95% ethanol: Colombia, Risaralda Department, Municipality of Santuario, Parque Municipal Planes de San Rafael (5.125°N, 76.002°W; 2107 m elevation), 12 February 2022, C. Valencia, G. Tezna, D. Corredor, J. Cabra-García leg. Paratypes: 4 ♂ and 4 ♀ (MUSENUV-Ar-2230-2237), 1 ♂ and 1 ♀ (ICN-AO-1969- 1970), 1 ♂ and 1 ♀ (MZSP-78901), same data as the holotype.

Diagnosis

Ocularium with two tubercles near each eye. Hourglass-shaped dorsal emerald-green spot pattern, beginning as two stripes next to the ocularium and continuing to the posterior margin of area III ( Figure 1 (G, J)). Lateral margins with eight tubercles, with a small light emerald-green patch near the posterior margin ( Figure 1 (G, I, J, L)). Lateral regions of free tergites with a light emerald-green patch each ( Figure 1 (G, J)). Distal metatarsus I slightly swollen in the male ( Figure 3 (D)). Penis with VP trapezoidal, with microsetae type 3 distributed on the dorsolateral field, around the macrosetae, with two pairs of MS-E on its dorsolateral margin and stylus short ( Figure 4 (D–F)).

Comparisons

Similar to Q. bella , Q. bimaculata , Q. discolor , Q. hermesi , Q. marginata , and Q. sanantonio sp. n. due to the lack of enlarged tubercles on the posterior lateral margins of dorsal scutum. It differs from the latter species by the presence of an hourglass-shaped pattern of emerald-green dorsal spots.
