P. agallithoplotes Gustafson, Short & Miller, 2016

Source of material. The larvae studied were collected in association with adults at the following localities: Venezuela: Bolivar State: Los Pijiguaos; morichal / rock outcrop, 80 m; 06°35.617’N 66°42.238’W, 16.ix.2007, one instar II and two instar III, leg. A.E.Z. Short, M. Garcia, L. Joly; Río Aponwao, small streamlet, 1340 m; 05°.50’.49.2N’’, 61°28’.2.4’’W, 31.vii.2008, one instar II and one instar III, leg. A.E.Z. Short, M. Garcia; 2 km East Río Chucivero, rock outcrop seeps, 45 m; 07°.29’.47.3’’N, 65°51’.44.8’’W, 06.viii.2008, two instar III, leg. A.E.Z. Short, M. Garcia, L. Joly; Los Pijiguaos, stream at outcrop, 80 m; 06°.35.617’N, 66°49.238’W, 08.vii.2010, one instar I and two instar III, leg. A.E.Z. Short, Teles, Arias; Rock outcrop by morichal, 75 m; 06°.52.196’N, 66°35.405’W, 09.vii.2010, three instar III, leg. A.E.Z. Short, Teles, Arias. Larval specimens were collected in seepages on granite outcrops of Guiana Shield (see figures 20–21 in Gustafson et al. (2016)). In most cases, these seepages are seasonal and go completely dry for part of the year.

Diagnosis. Larvae of P. agallithoplotes are unique within all known Agabinae by the presence of numerous additional setae on the cephalic capsule (Figs 1–2), abdominal segment VIII (Figs 12–13) and urogomphi (Fig. 14). Among other unique characters that facilitate a readily recognition of this species within other known Platynectes described in detail (i.e., P. bakewelli, P. curtulus, P. davidorum, P. decemnotatus, and P. reticulosus) are: the presence of six lamellae clypeales (instar I) (Fig. 1), prementum subquadrate, as long as broad, not fully sclerotized ventrally (Figs 8–9), primary seta TA1 inserted medially (Fig. 11) primary setae AB8 and AB14 lanceolate (Fig. 12), presence of several hair-like setae notably on metacoxa, metatibia and metatarsus (instar II–III) (Figs 24–25).
