Etymology. The specific name is a noun in apposition taken from the type locality of one of the female paratypes.

Diagnosis. Decaphora kohunlich spec. nov. resembles D. pestai (Reimoser) by mRTA with many distal spines and dRTA very long and slender in the male palp ( Figs 23−24 vs. 30–31) and by lateral lobes of the female epigyne with posterior triangular projections ( Figs 26 vs. 34). The males are distinguished by vRTA with short, rounded projection at base, slightly pear-shaped TBC and distally rounded TBE ( Fig. 23 ). The females are distinguished by the atrium at least three times wider than long, anteriorly indented and by the lateral lobes with a posterior excavation ( Fig. 26 ).

Description. Male (MCZ 79977): Prosoma orange brown with faint brown margins and faint brown lines along thoracic striae. Chelicerae, legs and pedipalps orange brown. Sternum pale orange with slightly darker margins. Endites orange, distally cream colored. Labium orange brown, distally orange. Opisthosoma cream colored, dorsally with irregular brown markings on anterior half and laterally and brown pattern of five median, inverted V-shaped marks on posterior half, ventrally with scattered brown spots ( Fig. 3 ). Total length 8.3. Prosoma: 4.2 long, 3.7 wide. Opisthosoma: 4.0 long, 2.5 wide. Eyes: diameters: 0.32, 0.23, 0.18, 0.23; interdistances: 0.20, 0.06, 0.41, 0.32, 0.15, 0.07. Legs (1-2-4-3): I: 15.7 (4.5, 2.2, 4.3, 3.9, 0.8); II: 15.6 (4.6, 2.1, 4.1, 3.9, 0.9); III: 12.5 (3.8, 1.9, 2.8, 3.1, 0.9); IV: 14.7 (4.4, 1.7, 3.4, 4.2, 1.0). Leg and palp spination follow the generic pattern. Palp: tibia short with one prolateral spine; PTP long and cylindrical ( Fig. 23 ); embolus with subdistal, slightly serrated keel ( Fig. 25 ).

Female (MCZ 30718): Coloration pattern as in male. Opisthosoma with denser dorsal pattern ( Fig. 4 ). Total length 11.1. Prosoma: 3.8 long, 3.5 wide. Opisthosoma: 6.6 long, 3.6 wide. Eyes: diameters: 0.26, 0.22, 0.14, 0.20, interdistances: 0.20, 0.16 0.40, 0.40, 0.18, 0.10. Legs (1-2-4-3): I: 12.4 (3.6, 2.0, 3.1, 2.8, 0.9); II: 12.3 (3.6, 2.0, 3.0, 2.8, 0.9); III: 9.3 (3.0, 1.1, 2.1, 2.3, 0.8); IV: 12.1 (3.5, 1.6, 2.6, 3.3, 1.1). Leg and palp spination follow the generic pattern except: femora I −IV: p2; tibiae I −II: v2-2 -2-2-2-2; tibia III: v2-2 -1p; tibia IV: d0; metatarsi I −II: p1- 1-0; r1-1-0; metatarsus III: p0. Epigyne: Touching part of lateral lobes two times longer than median septum height ( Fig. 26 ). Vulva: blind-ended projection inconspicuous, closer to antero-posterior loop than to copulation openings; fertilization ducts curved anteriorly and pointing away from each other ( Figs. 27−28 ).

Variation. Males (n = 2): total length 8.2−8.3; prosoma length 3.8−4.2; femur I 3.8−4.5. Females (n = 3): total length 8.3−11.1; prosoma length 3.6−4.4; femur I length 3.0−3.8.

Distribution. Known from Mexico and Guatemala ( Fig. 46 ).
